me again! machine died during O/C - dodgy RAM?


i posted earlier today about failing to get my rig [2100+ on a7n8x del rev2] to work at 200*10.
i then figured i'd try to see what is the cause and booted it at 200*9.5, with the ram timings at spd and at 8-3-3-2.5

it booted up fine and i had mbm5 running to keep an eye on temps.
to test the mem i ran the memory bandwidth and memory cache burn in wizards on sisoft sandra.
it passed 1 round on the bandwidth but when it was doing a cache and memory benchmark [temp was only 53C] i suddenly got a blue screen with:

"A problem has been detected and windows has been shutdown to prevent damage to your computer.
A wait operation, attach process or yield was attempted from a DPC routine.

Techincal Info:
STOP: 0x000000B8 (0x00000000, 0x00000000, 0x00000000, 0x00000000)

i have now put it back down to 166*12 [which is still o/c i know but i have run this for months with no probs] and it finally decided to work again .
Before this i have never had a problem running

technical info: 2100+ auihb at 12*166, vcore = stock [1.60], ram = twinmos w/winbond BH5 PC3200 running in synch [currently 166MHz at 5-2-2-2] agp = 66mhz stock vmem

do i have dodgy ram that doesnt run at 200MHz even thogh it is supposed to? what else would cause that error


my cpu runs so hot I dont need central heating in my house!

More about again machine died dodgy
  1. It cud very much be that ur CPU is maxing out at about 2000MHz. I say this because, even at the stock voltage ur CPU full load temp is a little more than what we normally see. Speeduk's 2100+ reaches 2.35GHz at 1.9V and still his full load temp reaches about 60C.

    I dont think RAM is the problem. Anyways, i suggest, if u have access to any other system, do check the RAM on that system.

    Mostly its a crappy CPU u have got there? Are u sure its a t-bred B? because t-bred A are not as good overclockers as the t-bred Bs.

    I am sorry i cudnt help more.

  2. Try Memtest86 with cache disabled to test for RAM instability.

    I love my Delta 60HP 7000 RPM fan that puts out more dB then CFM :eek:
  3. yeah its definately a tbred b as i cherry-picked the stepping! it is a even a retail version and not an OEM!

    the temp has always been around this level from day 1 and admittedly i dont notice much reduction in temp [maybe 4C max] if i downclock it back to stock.
