Dare I say it, BT2 will hear me, however what mobo are you using with that Lynnfield chip and which socket does it have?. Are you sure it isnt RAM timings, or voltage droop?

837216 2009-12-07 10:37:00 Have you tried chjecking peoples settings and guide? http://www.overclock.net
People are having trouble OCing over 3.8ghz too so you're not the only one. Some that successfully OC over 4.0 used higher voltage of 1.4v+

The i7 860s need more volts with HT enabled, and I notice they even without, they like more volts.

837217 2009-12-07 10:37:00 cpu voltage is 1.38sometihng i think. the max recommended is 1.4 And temps vary per day but usually no higher than 50 which isnt bad considerin how much hotter these cpus run than the core2's

Err, you said before RAM speed was 1800, yet you run at 1800, and expect stability....on G-Skill? 1.38 volt with max 1.4 vCPU?....that is quiet high, some of the sockets for 15 core are not too flash either....I think your clock needs work!

837218 2009-12-07 10:40:00 I have my suspicion on the 1600 RAM running at 1800. Sure it's a decent G.Skill but maybe it needs more than 1.65v? I wouldn't increase the RAM voltage though. Just try something lower than 1600 if the multiplier rules out 1600. qazwsxokmijn (102)
837219 2009-12-07 19:57:00 +1 for ram

hueybot3000 don't overclock your ram. Overclock the CPU first and prove stability maybe over a week, then overclock your ram and see how you go.

Your Vcore is prob to high @1.38, but I suspect you are trying to compensate for your stability issue.

If you still have issues, post your entire OC settings.

837220 2009-12-07 20:12:00 Just a guess, but I would suggest your problem may be caused by overheating.
I have a 975 cpu in an ASUS Rampge motherboard overclocked to 4.2. It runs perfectly at that. Anything higher and it becomes mildly unstable. At 4.6 it won't even boot.
A month ago my core temps never went any higher than the low 60's. But now with the warmer weather they are up to mid 70's. When I see 80 the o/c will be comming down! I am told by Intel that 90 is the absolute safe maximum.
Make sure that your temp safety settings are not too low (mine are at 100), and that your fan speeds are set to maximum. Water cooling is essential.
Also a good PSU is essential.
A cooling fan for your hard drives is handy too.
Is your GPU up to the job. It can cause BSOD if not.
At the moment I am toying with the idea of getting a refrigerator to keep my computer in. The problem here is getting a sufficient air flow into the fridge.

837222 2009-12-08 01:50:00 Hey guys I checked my event viewer and it would appear the bluescreen is a Nvidia fault, which really doesnt suprise me as my graphics card has had a very hard life.

Ive just updated the driver and il give that a week or so to see if it fixes anything.

RAM is also running at 1900 so ive dropped the timings back a bit as well

837223 2009-12-08 02:04:00 Is it the exactly same error every time? Agent_24 (57)
837224 2009-12-08 02:12:00 yep, all the entries that complain about nvidia are right next to the unexpected shutdown error hueybot3000 (3646)
