CPR vs SDRAM

I just recently upgraded my memory from 32MB EDO 60 ns to 32MB SDRAM 10ns now when I start CPR everything loads up intill the car lurches out of the pits at that point in time I get the dreaded grey box that says, invalid instruction then gives an error code C000001D then my little world comes crashing down. Everything worked fine before changing the memory, and the memory was all that I changed. My system is Intel 233 OC to 250 ( 3 X 83 ) Diamond stealth 3D with 4 MB ram, a monster 3D card, 32 MB 10ns SDRAM , 5 gigs of WD hard drives, 10 X cdrom, Sb AWE32, all on a Tyan S1571S Titan Turbo AT-2 mb. Thanks Denny M

I have two different banks for the mem and have tried them both, with the same results. This afternoon I am going to try a different peice of mem, but I am not holding my breath because CPR is the only thing I can,t make work. The other games and programs work fine, it even runs winbench98 without a glitch. Thanks for your replys Denny M

I don't know if this is the situation in your case, but I have known "bad memory" or mis-matched memory to cause problems like this. Is there another bank to try the memory in? -- **************************** Michael E.

What brand of SDRAM did you get? Motherboards can be very picky about SDRAM, so you're best off sticking with one of the big names like Corsair. -- Eric T. Busch http://ebusch.akorn.net

I've got SDRAM (96 megs) on this machine, and the CPR demo runs fine. However, it is the memory that came with it, so I don't know if the upgrading has anything to do with your problems or not. Is your SDRAM ECC - does it have the gold plated leads? For what it's worth, - Mike. ============================================ Mike Holthouse - Indianapolis, IN My new philosophy is to never explain my philosophies.

: What brand of SDRAM did you get? Motherboards can be very picky about : SDRAM, so you're best off sticking with one of the big names like : Corsair. Another thing to try is remove the overclocking just for a test and see if that is possibly causing a problem.

Thanks everybody for your help, it turned out to be a bad peice of memory, it didn't like CPR either. Denny M >% I just recently upgraded my memory from 32MB EDO 60 ns to 32MB SDRAM >% 10ns >% now when I start CPR everything loads up intill the car lurches out of the

I was not aware you could use a 83mhz bus with mere 60ns EDO. Are you sure you were running 83 x 3 before? In any case I would say you need to tweak the memory timing in CMOS. I feel certain you would need to adjust that going from EDO to SDRAM.

I don't know about anybody eleses computer but mine worked fine with edo at 3 x 83, with the different sdram it runs fine with it to. Thanks again Denny M >> Thanks Denny M > I was not aware you could use a 83mhz bus with mere 60ns EDO. Are >you sure you were running 83 x 3 before?

Microsoft software products have always been good ram testers, they are such memory hogs that if you keep getting invalid page faults you can bet you have some type of memory problem. I had this happen to me recently but also confirmed the bad simms with Nuts & Bolts ram diagnostics.

Is the Nuts & Bolts RAM diagnostics a utility that can be downloaded from the 'net? If so where can I find it?
