Hi,

I've got an old white box with an EliteGroup (ECS) K7S5A (Rev 3.X) motherboard, which has 4 memory banks: 2 for SDR SDRAM modules (168-pin) and 2 for DDR SDRAM modules (184-pin).

It supports non-ECC, unbuffered modules only, up to a total of 1GB. Currently has one 256MB SDRAM PC133 module in it and I want to add a new 512MB module.

The issue is that Crucial's System Scanner recommends me to upgrade through a choice of DDR modules, while Kingston's website states that "This board supports both DDR and SDRAM memory technologies. However, they cannot be mixed at the same time."

So I'm pretty confused! Any advice?

The pages related to my mainboard I've looked up:
Crucial: http://snipurl.com/1tmns
Kingston: http://snipurl.com/1tmol
(I've given up at trying to find info on ECS' own website.)

MANY thanks in advance to everyone who can help!

Alberto,
Spain

Thanks for your input, caperjack!

So, in spite of Kingston's warning about not mixing the two types of memory on my mobo, you see no problem in doing so, then? Or am I missing something…?

I know DDR is faster, and I considered getting two 512 DDRs, but for the use I'm giving this box... I'd rather get just one - as long as it can work no-problem with that 256 SDRAM, that is.

no you can't mix them,one type or the other . as it clearly states in the link in you first post .

It does indeed. But the Crucial System Scanner detects my installed SDRAM and still suggests me DDRs to upgrade, and states nothing about not mixing types... So I'm still confused! Who should I listen to??

Kingston+caperjack VS. Crucial (?)

Sorry. I need consensus!

THANKS A LOT Joe !!

Funnily I never got to upgrade that PC back in the day of my post (over 2 years ago, man!) so your info comes in handy! Now you've reminded me about it, I'll try to do the upgrade asap so we squeeze some extra life from that old box.

Cheers!
