Shuttle refuses to boot with RAM upgrade

Stringy · 7 Jan 2008 at 12:14

I bought 2 x 1GB pc3200 Corsair XMS off the members market to go in my ST20G5 in place of 2x512MB Corsair Value. When I put the 2 sticks in the computer refuses to POST, and doesn't throw up any error beeps or anything. However, each stick individually works fine, and I know both slots work as the 2x512 worked when I put them back in.

Anyone got any ideas?

edit: It'll even boot with 1x1GB + 1x512MB for 1.5GB total :confused:

Does your new RAM require extra voltage? I know some RAM needs 2.0 or 2.1V to run at then advertised timings. I believe DDR2 spec has 1.8v as default.

Well I played with the voltages to no avail

Any other suggestions? Is this something that updating the bios might cover? Will go floppy drive hunting if so.

I'd def get the BIOS flashed and also do a full reset of the bios via the jumper etc.

I'd also test each module with memtest

BIOS flash achieved nothing...

So, 1.5GB in single channel, or 1GB in dual?

edit: or have I misunderstood the concept and 2 unmatched sticks can still be dual??
editedit: nope, working in single chan, so the original question stands
