What is the exact problem in running PRIME95/OCCT? What happens when you try to run them? Also, have you downloaded and run memtest86+ through at least two complete passes without errors to make sure the basics are stable?
I think you meant "memtest86+". That's good to make sure the basics are running right.
When you say both Prime programs "crash" right away, do you mean they report errors, or that the program hangs/disappears? I'd re-install Windows and Prime/OCCT to make sure it's not just that Windows and/or Prime have become corrupted. Also, make sure you have set you DIMM/RAM voltage in the BIOS to the spec voltage for your specific model number DIMMs.
RAM/DIMM settings are correct for the sticks: 2.1v, 5-5-5-15 (manual) for the speed (533.9 x 2 = 1067). Also had tried Auto, no diff (except Auto placed the timings at 5-5-5-18).
EPP confirms the settings.
Windows was re-installed once, and both Prime95 and OCCT were re-installed several times to make sure I was using the most recent and an x64 (Vista) version.
Both programs hang and crash as soon as testing is started.
I get no reports from either so I believe they won't run under x64.
This is why I am posing the question, as I am hoping I am wrong.
surely high end gamers with 64 bit OS's and high end gaming machines would be running those stress programs! i mean, who would be running an sli rig with 4 or 8GB of RAM with a 32 bit OS that holds em up!
First set your RAM to 1:1 then, I'd guess you ned to increase the vcore a tad more. You've obviously have it at least boot stable (getting past that damned vista screen is such a tease ), however to get it to bench stable you'll need a few more tiny vcore increments to get it at 24/7.
Once your bench stable then tweak the RAM, to be honest running it 1:1 maybe quicker even at 400FSB (test with super PI 1M test). If you want that RAM used then lower the multi to 7 and eek the max FSB from the mobo. A good board can hit 500 with a little tweaking 520 you only need 515 so maybe a goal to reach .
According to the mobo manual, FSB can be anywhere from 200-800MHz, entered directly from the keyboard (page 4-17, FSB Frequency).
That is were I got the FSB numbers from. I kid you not!
I just changed the RAM ratio to 1:1 and added 1 step higher to the V-Core voltage (now 1.475). Booted OK.
Then I attempted to play with higher FSB numbers (like 420, 434). Changed the RAM ratio to 1:1 to match. Upped the Vcore (in increments) to 1.525. Hardware crash every time, both FSB values. Since I am only using stock coolers on the North- and South-Bridge chips, would that have anything to do with the hardware crash at those higher speeds?
Might be onto something here. I changed the NB voltage from Auto to 1.4v
Then I changed the FSB to 421, RAM at 1:1, Vcore at 1.5375. I was able to boot and log into Windows, no hardware crash.
I ran SuperPIMod 1.5, it got as far as 10 loops completed (at 32M setting).
56'C core 1, 42'C at core 4. Max load it placed though was 65%.
Still cannot run Prime95x64.
I did find one recent post on another board, the author was able to run his Prime95x64 under Vistax64 by not loading his nVidia drivers. ??
(I have a nVidia card, drivers loaded).
no, I don't. Actually, I did have a copy, oem, but the oem number on the computer case it came with didn't work (some variation, I discovered, made it incompatible with my oem disk. I have since sold that case with the disk.
(namely, when I had enough pieces to put this build together).
