i7 930 4.0GHz OC - Opinions?

post #1 of 42
Thread Starter 
So I finally got around to OCing my 930, and I've been playing with settings all day. I just stopped it from a prime95 blend run after an hour and a half only because I want to tweak things a bit before I let it go on a 12+ hour run over night/into tomorrow.

Settings I Changed
AI Overclock Tuner: Manual
CPU Ratio Setting: 21x
Intel SpeedStep Tech: Disabled
TurboMode: Disabled
BCLK Frequency: 191
DRAM Frequency: DDR3-1531MHz
UCLK Frequency: 3063MHz
QPI Link Data Rate: Auto
CPU Voltage: 1.24375 (Anything under would BSOD)
QPI/DRAM Core Voltage: 1.20000
IOH Voltage: 1.10
DRAM Bus Voltage: 1.65
Load-Line Calibration: Enabled
C1E Support: Disabled

How do these settings look? Should I change anything and/or tweak some other settings?

Temps were around 40-43C Idles and 71-75C Loads. Ambient was 27.6C.

That's perfect !
Try to push it to 4.2GHz maybe ?!

That looks great! I'd recommend running the Prime95, before pushing it any further. Good temps to.

Sweet I'll run prime and check it tomorrow morning. If it's still running I'll check it after work.

Forgot to mention, HT is on.

Welp my computer rebooted which is odd because I have it set to not reboot when it bsod's.

Event viewer says this
A fatal hardware error has occurred.

Reported by component: Processor Core
Error Source: Machine Check Exception
Error Type: Internal Timer Error
Processor ID: 4

So I'm assuming the vcore is a tad too low and I have to bump it up to 1.25v. I guess I'll be checking back after work.

If your hitting 75 at 4Ghz and only with 1.24375 then id take a look at better cooling if you want to push further.

Myself id accept your current overclock and wait for better cooling before you push further.
4Ghz is not to be sniffed at especially with hyperthreading as well

I'm lost, you have cpu coltage and qpi/dram voltage listed twice. And also, those temps were with near 28C ambients. Cooling has been checked and I've re-seated before. I could ramp up the fans (AP-15's @ 1400rpms, case fans at 1200-1400rpms) but would rather not.

Also when I was playing with settings yesterday it seemed the BSOD's would come later the further I pushed my vcore, so that makes me assume it is vcore that might be the issue (This morning's BSOD came around 7 hours after I started Prime95 Blend).

If I come back from work with a BSOD from the 1.25v I'll give your settings a try.

On a side note, with the stock intel cooler and the stock cooling in this case (before I upgraded anything) I'd idle around 60C @ 26C ambients. I think I just have a hot chip.
