i7 930 4.2OC failed after 15 months stable - Page 2

post #11 of 21
turn pll down to atleast 1.8. Then loosen your timings to cl8 and see what happens

Edit: Actually reading over it , it doesnt sound like either one. Maybe your mobo is going dead. Boot up at like just a little over stock and run p95 for awhile

OK Beefdog, I'll try it. Got the PLL not sure what you mean about the timing. Make them all 8? Like 8-8-8-24?

I was just gaming (Company of heros against the AI, not online. It crashed after 35 minutes. I can go to default settings and rum Prime95 and see ehat happens.

you need to isolate things..

lower just CPU multi leaving uncore and QPI/RAM alone.. re-run tests
Raise CPU multi back and lower RAM speeds leaving QPI and Uncore.. re-run
Raise RAM speeds and lower QPI.. re-run

*You wont be able to lower uncore as your already running the lowest divider for your RAM speed... so if you get through the above without failure.. you need to start looking towards your uncore voltages in BIOS, as well as skew.

This happened the me recently, turned out that one of my video cards was going bad and affecting the motherboard, which it eventually fried. I doubt you have the exact same issue as me, but it could be your motherboard instead of your CPU.

I give it go, How about cleaning out your blocks dude. Methinks there could be some build up causing instabilities...

Yes, go to default setting. I would disable any energy saving features. 133 x 20. Lets hope that does not fail

I highly doubt it.

Thanks for all the help. Actually I vaccumed the MOBO last week when I tested each memeory stick individually, there was no observable lint at the time. OK here is an update: I had to lower down to 2.8 MHz (stock for the 930 of course). It was not stable at even 3.2MHz (the Blend test in Prime95, all workers stopped in 6 minutes).
Here is my current BIOS settings

Ratio 21.0
BCLK 133
PCIE 100
DRAM 1603
UCLK 3208
QPI Link auto

CPU voltage 1.30000
CPU PLL 1.80
QPI/DRAM 1.30000
DRAM Bus 1.64
Everything else auto

Last week I set CPU Ratio to 12 and worked slowly up to a stable tested BLCK up to 220. Then I lowerd the BCLK to 150, changed the multiplier to 21 and that is when it would not boot up Windows 7. I kept increasing CPU voltage and retrying to boot. When I di get over 1.45 Windows almost booted, but got BSOD. (Too fast to get error code). I went up to 1.46250 with no real improvement. I also increased QPI/DRAM core voltage to 1.4250 when I finally stopped. My water cooling kept things safe I'm sure.

I'm wondering if it is my video card. My game crashed often lately, and the 3dMark Vantage score was really low, like low 20's frames per second. When new, I think I recall it was closer to 50 or more? Maybe that was with the test within the game, can't really recall. It is definitely a hardware issue. Just hard to know what piece of the puzzle.

try a different gpu. The problems seem strange. Lose the ram timings to like 9-9-9-24 to completely rule them out. I know how frustrating this can be. I would start switching part by part (yes a pain in the A$$). I will run it over my head and see if I can suggest something better.
