You can manually set memory settings, yes. By default, BIOSs use an automatic timing function known as SPD (Serial Presence Detect) to configure these timings. You should be able to use "manual" settings instead and configure the numbers appropriately.

Thanks for all your input guys.

dcc, Ive got the Thunder K8WE, which as far as my product lit says, will accept the memory I purchased. Also, the pairs are matched (serial numbers are sequential A+B in CPU-Z)

I think I'll avoid resetting the SPD timings right now, given that we shelled out about 10 grand for the functional unit.

I've broken enough 'things' in the past to know better at this point.

thanks for all your input, all of you.

KRX3200AK2/1G 1GB 400MHz DDR ECC Registered CL2.5 (2.5-3-3-6-1) DIMM (Kit of 2)

Close, KRX3200AK2/2G 2GB PC3200 REgistered CL2.5 ECC (a pair of 1GB pairs)

it doesnt really matter if I can only achieve 200MHz with 4GB dual channel matched pairs per socket, its the addresses and bitwidth I want, not the bandwidth so much.

I've read that some boards wont support full bandwidth on a full-set of memory modules per socket, is this what you're thinking?

thanks

Best thing to do is to take each individual part, and price it out using a site like www.newegg.com. Total that up, and then figure you're only going to get about 60%-70% of what it's worth brand new, if that. Then, you can post it on a place like eBay.

Or, if that fails, I'll give you $20 for the whole lot. I'll even come and pick it up. :)

(joking, unless you really want to sell them to me for $20!)

I'll bid $25.00 and send my cute sister to pick it up.:cheesy:

I have followed the instructions on how to apply the thermal grease and heatsink on arctic silver's website and still doesnt get any cooler.

What volume of paste did you apply and did you clean the heatsink and processor lid well with acetone before applying the new goo?

its very important to have perfectly clean faces for the thermal paste to work right, and that you use the correct volume of goop. usually, all you need is a dab the size of a grain of rice on the middle of the lid. too much paste will actually decrease it's efficiency.

I added your quote above because you said you did these things, but applying too much paste between dirty surfaces seems to be the major cause of (non-overclocking and bent-pin) overheats.

A quick question for you guys: I just built a 64-bit workstation at work and the DDR400 memory I purchased is running at 200MHz.

Specs:
Tyan K8WE mobo
Opteron 64 270 @ 2.0GHz dual core
4 GB Kingston HyperX KRX3200 (2 pairs of 1GB matched ECC/R sticks) dual-channel 128-bit interleaved.
5 Raptor 150 GB HDD (4 in RAID1, 5th as OS disk, raid via 3Ware 9550SX SATAII card)
Windows XP Pro x64

CPU-Z shows that both cores are recognized and running, everythings cosher with the 64 bit, but the memory is stuck at 200 MHz (3-3-3-8). Now the specs from Kingston show the timings should be 2-3-2-6 @ 2.5V

Now, Ive never built such an enourmous workhorse, or at least one that I needed to tune as finely as I do this one, so I'm no pro at tweaking the settings.

Do these look like normal default settings to you guys and should I drop the hammer on the timings?

TIA,
gkd

Is it safe?

ANd if so where can I find one, no PC place around here sells ones. And the ones on sites i have looked at (directron, newegg) just have the pumps. Where I can get the whole setup.

Why dont you try a peltier cooler? they may not be nearly as 'cool looking', but unless youve got a constant temperatue water recirculator cooling the water over your chip, then youre really not cooling much. you can easily achieve sub zero temperatures on the cold side of a peltier. you might need a water cooer for the hot side though, but ive noticed that a nice big fan works well.

theyre cheap, theyre available from almost any electronics supply catalog, theyre easy to set up and if youre not an eletronics engineer yet, hardwiring it to your mainboard will make you feel like one for a while.

Hi all, its been forever since I've posted. Ive got an all-consuming hardware question.

First, let me set it up: Since Ive graduated I began to work at a biomedical research firm. We do massive amounts of data analysis, most of which is computed tomography and 3D image analysis. Currently, we are significantly limited by the (lack of) power of our machines. Our workstations are windows2000 based DELL PCs that are decked out at the factory to 2002 standards. A set of our workstations can and do process up to a Tb of data daily.

I want to build the ultimate volume-rendering, data-thinning, most powerful machine I can, where cost is not an option. I used to build my own PCs regularly but since Ive been in school (and now out) I've been into other things.

If you can think of a 64-bit platform and an image processing IDE I can use to address it, tell me.

whats my dream 'thor's hammer' workstation?

Er...um. :o

Sorry for the stupid thread. I developed a realy cool solution to my problem that reads each value from a CSV by splitting the string and then appends the file onthefly ('kind of') to a temp file, for which a new CSV line is written everytime the program goes through 10 iterations of the calculation, then at the end of the routine reads the final values (last lin) from the temp file which are written into the the app and then optionally saved into original file and stored as the resultant theoretical solution properties.

Im working on a method to compare this to lab measured values now.

thanks for all your help.

So school's out for a month and Ive been doing some hobby VB6 programming...

Im writing calculators involving up to 25 variables, many constants, etc, etc, etc..

So, instead of requiring the user to input all the vars I thought I'd allow the loading of comma- or tab-delineated textfiles with appropriate values already there for particular cases.

For instance, to calculate the concentration of an organic acid in equilibrium with X other species in solution of X unknowns at, say, standard temp and pressure; all the user would have to do is load that file and input one or two values. Additionally, I would like to allow for saiving the file if the user wanted to change the inputs for compund- or solution-specific, non-ideal conditions...

So can you all recommend a simple tutorial that will discuss the process of how to load/save the files?

TIA!:)
-gkd

I did this exact same thing - hobby programming. Actually I started writing calculator programs that applied some of the complex mathematical chemistry tools I had been computing longhand.

The solution for me was to go to my local college bookstore and buy the academic version of VisualStudio 6 for 100 bucks. VisualBasic 6 was only 60 clams.

As a teacher you should be able to get some price-break if you also use it in your curriculum.

Does anyone know of an easily programmed, web-based GIS server or applet that's small but buildable for my improvements? Ive got a few in mind, but thought I'd poll the genious pool here. Keep in mind that I am time limited by week, and only have until July 2005 to finish surveying and data collection.

If you are scratching your head - here's an overblown example of the project: http://www.geodata.org (click "online maps").

Firstly, I'll concede that there is some value in the "drag and drop" programs that will graphically put a site together for you. When i need a very complex table built, I'll go to Dreamweaver and export it, for example. They do make some things easier.

That said, I'll say this: if you are serious about building and maintining your own site, do not overlook the virtue in learning how to hand-code HTML at the very least. I learned years ago at http://www.htmlgoodies.com and have since utilized many other sites like asp101.com, four guys from rolla, etc - work up to those.

In this respect - if your using a PC - I would say that the best "free" software for building webpages comes with your PC - its Notepad!

You can make it fun and, while they wont look on-the-mark when you stat, you'll continually get more sophisticated as you learn. Also, you'll be able to update it much more precisely and with greater efficiency if you can hand code updates and other "tweaks".

HA!

yes, thank you both!

first, its a mainboard malfunction or power supply - i think. im not too familliar with the inards of laptops. the drive was working perfectly right before the power shut off. and now it wont turn back on and I can barely get the power adapter into its socket (it was HOT).

I did find the 2.5 to 3.5 inch converters online for 30 bucks and promply called the nearest parts store and had them hold one for $9.99. I'll pick it up tomorrow.

I do back up my data weekly, but this is the 5 gigs of data that i was working on this week, which takes too much time to burn a CD of before processing it (the final filesets are much smaller).

Thanks again!

My laptop up-and-died today with ~5 gigs of valuable GIS and hydrology work on it. I desperately need to recover these data. I've got the HDD in an antistatic bag next to me and I'm wondering if there isnt an adapter utility to plug the li'l SOB into a 40-pin desktop cable so I can retrieve the data?

Right now, the data are orders of magnitude more important than the machine (and cash is a limitation) so dont worry about the computer - I simply need to know how to get my LIDAR data back.

I am so seriously screwed if I can't recover this work because there is no way I can replace it in time.

anybody have any hints?

Thanks in advance

Side note (or bottom note?): I definitly see where you are coming from, and it is a valid way of looking at the issue. It's just not the road I'm taking with regards to it. Interestingly enough this is one of those things that can be looked at several different, ways with the perception being valid, without redifining or twisting terms to fit one's view. I just found that interesting.

This is interesting. I keep returning to the consideration of the idea that the knowledge of some fact r is, in and of itself, power.

I'm considering the knowledge of some 'thing' to be the simple memorization of a fact or value about that 'thing'. For example, some alphmetic equation (I'd use an arithmetic value, but that'd bee too simple to evaluate my example by) - alphametics is the study of single letters representing single unique digits which are then processed by arithmetic values to obtain letter sums - its recreational pseudo-cryptography.

If I only gave you the knowledge that j=7 and q=3, could you tell me what the following values for (x) and (p) should be?

(1) j+q=x, or
(2) q+p=j

Now, in terms of knowledge (through my definition if knowledge above) all we know is that j=7 and q=3. By using our knowledge of the two values I stated, we couldn't find for x, could we? We would have to memorize all the values for all letters for which values had been assigned. …

Interesting treatment. I hate tracking, but I'll do it anyway...

?Compatibility and similarity are not the same thing.

You're somewhat correct - dependant upon the context - but this is not what I'm talking about. Granted, this is the most semantic discussion I've had in a decade, but there are still some very logical principles here. In fact, the only way - IMHO - to discern any truth in this discussion, is through logical truth functions. While knowledge and power themselves do not share symmetry, they may be individual elements of some higher truth (another discussion altogether). Notice my use of small "t" versus caps "T" in the word truth, ultimately the understanding of fundamental Truth, even when it applies to knowledge, is a personal determination and beyond the trivial scope of this message board.

I can see your point on the two not being similar or mirror images of one another (as a perspective). However, just because two things are not the same does not mean they are not compatible. Personally, I think knowledge and power in today's society are the same.

On an elemental level, what I'm saying is that knowledge and power are neither mutlually exclusive or mutually inclusive. There is a great deal of complexity here, which is why I applied some simple logic to my statement (notice the conditional). ie:
...
IF Knowledge=the accumulation of factual data
AND IF Power=the ability to develop spontaneous advantage over a competitor
THEN …

Here's the deal ... we're in need of a 468x60 banner that we can use for web promotion or to give out to people. Since I'm certainly no artist I've decided to turn it into a design-a-banner contest!

All you artists out there, you have until December 31st to come up with a banner for us. (The deadline may be extended if we don't receive enough submissions at which time it will be announced.) During the month of January, all of the submissions will be entered in a poll.

...

Rules:
Only one submission per person.
The banner must be 468x60 in size.
The banner must be less than 10000 kb
The banner can advertise TechTalkForums.com, DaniWeb.com, Dazah.com, or any of their subsections/subforums.
If you choose to use a slogan, use "where cool techies unite."
Please post submissions as attached files as a reply to this thread.

For clarification: must the banner be a static jpg or gif, or can it be a flash swf that meets the size requirements?

What I did was right click on My Computer and click Properties. Then click the Automatic Update tab. Then uncheck to "keep my computer up to date" to disable automatic update.

According to the study, which I provided a link to, theres more than just unchecking the "recieve automatic updates". shutting down the "background intelligent transfer service" and "automatic updates" as services is also required, evidently.

see page 7 of the link I provided in my origninal post.

I use Win2000 sp3 on allmost all of my computers, I'm also a little aprehensive about my PC being able to communicate with Redmond in any manner which I am not in complete control of. I know we've all heard that MS builds backdoors into its OS's and blah blah blah...

Evidently, with SP3 for Win2000 the automatic update feature does send packets to and recieve packets from Redmond without letting the user know. Since I use SP3 I of course wanted to stop this. I think some of you also might want to keep your computer from doing this too.

It should be noted that all the packetlogs said the computer was doing is autoupdating, but I still dont want my PC doing anything automatically - or at someone else's request for that matter. here's how to nix this bug if you're not already familliar:

here's the study in complete detail: http://academic.evergreen.edu/d/dasgre16/auto-update_disable.pdf

I don't actually know what you mean by "for the same site" but the pop-ups usually are all the same kinds of advertisements.

This wont stop the popups, but will help increase your personal control over your own computer and clean up the content in the popups
.
If you can find out where the popups are trying to take you, write down the address, which will probably turn out to be something like: "ads.x10.com" or something. after you compile a large list of these addresses, throw them in your HOSTS file in %system%/System32/drivers/etc folder using this format:

127.0.0.1 www.adbanneraddress.com (thats not a real addy, btw)

what this does is create a kind of DNS "busy signal" for your computer so that everytime the browser is told to go to one of the sites in your HOSTS file, it gets looped back to your local machine instead. done.

I have a rather large hosts file that I'd be willing to give you, you can also get then on the web in different places.

I found that this eliminated one hole through which browser hijackings could occur and proliforate. I hope it helps you.

-gkd

When I go to talk forums and there is a picture to look at, I cannot open the picture because adaware is taking it as a pop up ad. The pictures are listed in the adaware setup as being blocked ads. How do I correct this? I can go to forums, open the discussion but not pictures or links.

:mrgreen: - I actually forgot about popups till you said this. Im using the Beonex broswer and KMeleon, neither of which have allowed a popup since Ive used them.

no cookies I dont want or activeX scripts I dont want, and I can make my own button/icon sets and write my own macros and behaviors.

I guess I forgot about the popups.

Don't let me butt in, but I have an addition to Bob's more-than-profound comments.

Based on the assumtion that power is derived from, or otherwise is faceted to knowledge, I'd have to agree with him in the idea that knowledge is not power. Basically, you must first define both power and knowledge. If power is the ability to develop spontaneous advantage over a competitor; and knowlegde is the accumulation of factual data, the two are not really compatible and knowledge is not necessarily in symmetry with power.

In that game, the only advantage you could glean over a competitor would be derived from factual data that your competitor did not also posess, which Bob pointed out early in the thread.

IMHO, a true advantage over competition is derived from the ability to reason, or process the data in a more efficient manner than a competitor. Anyone can memorize all the data in all the published games of Trivial Pursuit, but it does you no good if you dont posess the ability to compile that data and modify it fit external influence.

Now, define competition. :D (enter the game theory debate)

I just noticed your avatar. Its shows a small boy throwing a rock at a
M1 Abrams Main Battle Tank (MBT). Im just curious where this is at it can only be a couple of places in the middle east Iraq or the GAZA strip.
But what caught my eye is the text at the bottom. It says " Get Up, Stand Up". This looks like the average Terrorist banner in the middle east, except for the the towers are missing. Care to explain to a amercian. Just to clarify that your not taking part in the support of terrorist states such as Palestine.

Honestly, I'm not sure where it is, I assume its an Israeli tank and therefore the boy is Palestinian. The text is in reference to a popular Marley song, and I have no idea what an average terrorist banner in the Middle East would look like, with or without towers (this image was actually an old Reuters photo). As an American, am I required to explain myself to an American? I'm not sure how this 80px-square gif would support terrorist states such as Palestine, which is clearly a relative assumtion based upon ones political persuasion.

Personally, I see very little difference between this image and an image of - say - Rosa Parks throwing a rock at a white-only bus or an image of Colonists throwing stones at King George III. Would you take issue with those avatars as well?

Hmmm... take this suggestion only as a suggestion. I'm sure that someone else will be able to respond in more detail.

quit any disk utilities and make sure that no windows is displaying the contents of this drive. then try again." Please! help me! I cant find any way to stop running these programs.

Yeah *kicks self*

now that I re-read the post it makes more sense. It sounds like you're trying to reinstall windows from windows. You might not want to use linux fdisk to repartition your hard drive if this is the case, unless you want a completely new installation of win, which it sounds like you want.

I guess you'd need to make more clear exactly what it is you're trying to accomplish. You said that you want to "straight out format the disk", but it sounds like you're doing that while windows is running.

I'm not an XP user, but I dont think that this is possible in XP, it's not in any other version of win that I've used. Caperjack is right, you have to format your drive from a startup disk, which can either be a win bootdisk - or, like I like to use, a linux disk. you can partition with linux, but you'll probably want to format that partition at the time of installation with the XP disk.

While youre at it though, you might want to make a linux partition and install it also?

just make …

Hmmm... take this suggestion only as a suggestion. I'm sure that someone else will be able to respond in more detail.

I have no idea why you're running into this problem, but whenever I've needed to reformat (I used to do it quite a bit) I would use Linux.

Again, this is only a suggestion, and if you screw up your disks by doing this, I'm not responsible - just so you know.

The linux fdisk utility is great IMHO and gives you the ability to assign any partition ID to a disk partition. Use the linux instalation disk to use fdisk and create your partitions ("type m for help") I know for Win2000 the partition ID is "c" for Win95=>32bit formatting. You'll have to change this by "toggling the partition ID" (I think "t" from the help menu) because by default in linux fdisk the partition ID is set to 82 (linux native).

I hope this helps and that someone might further add to this or to the root of your current problems.

edit: i guess i should tell everyone why im trying to figure this out. i need to know cause i have been given a project at work to see if i can do with visual basic and the project invovles finding out the area of spaces like this so that they can do other info with the info. there is a program out there that can do this so i figure some how some way i must beable to do it. but the program they have found to do this will cost the company $50,000.00 :eek: and they dont want to pay that. but hopefully i will figure it out

I understand that this is a seriously aged thread, but thought I'd contribute a possible solution anyway.

It makes sense that you'd want to figure out how to process this on your own, but if your employer needs a simple, accurate and inexpensive digital solution for measuring real-size area, then peek over here.

the NIH uses, and makes freely available, a program called NIH IMAGE for Macs - which is also available for Windows from Scion Corp called Scion Image. I have used both for research and find that they measure area accurately to 0.1cm^2.

you can get NIH Image through the National Institues for Health (the mac version) and you can get Scion Image from Scion Corporation (www.scioncorp.com) (the windows version)
