Gigabyte X58 Extreme + 920 can't get to 4ghz

[zerosaku]

Can't seem to overclock to 4ghz :(

I can run at 3.8ghz with HT on with no problems, very stable..

My Current Settings:

Cpu Clock Ratio - 19x
Base Clock(BCLK) Control - 200

Intel Turbo Boost - Disabled
Cpu Cores Enabled - All
CPU Multi-Threading - Enabled
CPU Enhanced Halt (C1E) - Disabled
C3/C6/C7 State Support - Disabled
CPU Thermal Monitor - Enabled
CPU EIST Function - Disabled
Virtualization Technology - Enabled
Bi-Directional Prochot - Enabled

QPI Link Speed - x36
QPI Link Speed - 7.2Ghz
Uncore Frequency - x16
Uncore Frequency - 3200Mhz
Isochronous Support - Enabled

Performance Enhance - Turbo
Extreme Memory Profile - Profile 1
System Memory Multiplier - 8.0
Memory Frequency (Mhz) - 1600
DRAM Timing Selectable - Expert

Ram is set 8-8-8-24-1 [auto]
Profile DDR Voltage - 1.65V
Profile DDR QPI - 1.4v

Load-Line Calibration - Enabled
CPU Vcore - 1.31250v
QPI/VTT Voltage- 1.240
IOH Core - 1.120
DRAM Voltage - 1.660
CPU PLL - 1.880
Others - Auto

I tried 20x200 then Raise CPU Vcore to 1.4, and QPI/VTT to 1.4 so i could boot, but still always BSOD. I think my bios settings are correct.. please help

Note -> This is my 2nd Core i7 920, still can't get it to 4ghz.. zz

Do you actually get a BSOD? Your machine posts and attempts to load windows?

when i try for 4ghz.. Yes, i get the blue screen error when attempting to load windows.. then it will restart

Raise your ram volts to 1.68 or 1.7, the value listed in bios is not what it actually pushes. Try raising your uncore to x17. I'd loosen your timings a little to something like 9-9-9-28 and turn off that Performance Enhance thing, put it at standard.

if u turn of ht? boot then? my needs much more vcore with ht

Sounds like not enough vcore, for most processors you'll reach a point where you need a huge jump in voltage to increase in mhz. Easiest thing to do is bump it up to 1.5 see if it boots into windows then start dropping it until it can't boot into windows once you hit the point it wont boot windows bump it up a couple notches and then run some stability program, I use intel burntest and keep raising one notch at a time until its stable.

If it doesn't boot into windows even with 1.5 vcore try doing the same thing with qpi vtt start at 1.5 and work your way down.

If that doesn't work either bump up your cpu pll to 1.96 and start working your way down.

This is the fastest and easiest way to overclock.

thanks for the suggestion guys, i will try it later..

few hours ago i tried bumping the uncore frequency to 17x, still bsod
I tried 6x multiplier for ram and changing uncore frequency to 12x still bsod.
also everytime i try to disable multithreading my computer keeps turning on and off..

I think you should update you bios, I'm using F7C, it's wonderfull

i am using F7c..
