Gigabyte ex58-ud5 i7 920 6GB OCZ Obsidian At stock and fails in 8 mins on Prime 95 blend test if I run Small FFTs or In-place large FFTs it will cycle through each of the tests I have clocked the CPU to 4GHz in order to get the RAM to 1600Mhz and I have successfully completed a full pass on memtest x86 v4.0 with RAM timings of 10-9-9-22
Is the ram overclocked? Also in the BSOD screen, it usu tells you what went wrong at the top e.g for cpu it can say "one of the cores took longer than usual to respond" or something lik that
CPU has never been above 70 at stock the hover around 50-55 under max load Almost always fails with memory_management 0x1a error RAM never goes above 1600MHz I have been testing 3 cores with HT and it seems stable. I am going to try 4 without HT to see how it goes
have you tried loading optimized defaults in bios, then go straight back in to bios and set up you raid and memory settings and go from there with stability test
Yes I have now unplugged two of my hard drives so I now have no array and re-installed Windows 7 on a single drive to rule out the RAID array as the cause of the issue Just to summarise my testing: Run memtest x86 V4.0 at 1600MHz 10-9-9-22 I have cleared the CMOS then loaded optimised defaults in the BIOS Removed 2 of my 3 GPUs Taken my RAID array out of the equation by unplugging all the disks and using a separate drive which I have reinstalled windows on So at default frequencies and settings I have tested 1 core + HT = Stable 2 cores + HT = Stable 3 cores + HT = Stable 4 cores - HT = Stable 4 cores + HT unstable in fact it blue screens in less than 8 mins
What does the blue screen say when it comes up? That error can sometimes help you find out what the problem is. If you Google it.
