I'm running i7 with spec X58-UD5 ,etc (check sig) and managed to push i7 to 4Ghz stable with 1hr IBT and temp around 68c.

I tried to push to 4.2GHz and set BCLK to 210 but just won't boot.

Setting:

MIT:
- Advanced CPU feat
Intel Turbo: DIsabled
Multi threading: Disabled
C1E: Disabled
EIST: Disabled
The rest default (should i disable them?)

-QPI Link Speed: x36

-Uncore & QPI features:
Uncore Freq: x18

-BCLK: Enabled
BCLK: 200MHz (won't boot @ 210MHz?)

-Advanced clock control
PCIe: 100 MHz
The rest default

-Performance enhance: Standard

-SPD: 8.0
MHz: 1600
Timing: Manual
7-7-7-16 CMD 1 (default)

-Load Line Calibration: enabled
CPU vCore: 1.23125
QPI/VTT Voltage: 1.175 (AUTO)
IOH Core: 1.100v (AUTO)
DRAM: 1.640

Any advise :D

Thanks
 
1St would be up the volts I'm @1.25.


Ive got the faster memory than you but I cant do 2 runs of IBT but I havnt changed anything apart from BCLK and DRAM volts

I'll give your setting a try and see what happens to my system
 
Managed to get stable with multi thread enable but had to change spd multiplier to x6 instead of 8 so only get around 1200Mhz.

Any suggestions so i can OC my RAM to max as would like to run around 1600 MHZ

Don't think my vCore as it is stable now with the same voltage.

Thanks
 
mine would do 3.8@ undervolted but any higher required a boost.

Not sure if my mem is causing probs
200Mhz says 1066?? (1586)?? in bios

Not sure how the multiplier works

I want to run @2000mhz
Is there a formula for working out the settings.

Dont mind running it lower until tested CPU.

Sorry for the slight hijack but I believe its relevent to both of us
