Can you guys help me what is the correct setting on Gigabyte EX58 UD5 motherboard bios for 4.00Ghz and 4.20Ghz for overclock. My warranty with overclock bundles had now ended. :( So, I don't think Rich can help me further now but maybe he will if I ask him nicely.

I should have stored manual settings in my folder (penflash)

I am currently using 2.67Ghz stock speed at the moment as my ocuk profile had disappear from the bios after updated latest firmware version. I can't find my penflash (overclock bundle on it) must have lost it. :(
 
For the amount you have overclocked i'm suprised you can't remember the settings yourself, I can still remember the overclock I had set for my Q9650 @ 4.4ghz :p
 
Oh dear bulldog

4GHz:
Vcore: 1.30
Dram Vcore: 1.64
PCI express freq: 101
Dram multiplier: 8 (to give you 1603)
BCLK: 200
Multiplier: 20x
Memory timing: 9-9-9-28-2
CPU differential amplitude: 900mv
PCI differential amplitude: 800mv

For 4.2 adjust accordingly

Many thanks for this, but can you give other setting for the one with 191x21 something like that ? and vcore 1.30v is seem too high (leads temperature to 85C) or was it to do with most stable one ?

If it is stable at 1.30 vcore just lower the vcore gradually until it isnt stable and then put it back up a notch then you have found your lowest vcore.
 
The memory ram 8x multiplier at 1604mhz isn't showing anymore, it only show as 1600mhz (4mhz extra are gone ?)

are these ok ? was it cause to end up BSD ?

I did the same setting what NathWraith told me of bios setting. I had done 20x21622 linx as it error after 5 runs, try Occt got error after 7 mins, try prime95 blend got 6 cores running but 2 other cores stop running, stopping working on cores 3 and cores 6.

It used to be stable before (24 hours on prime95 last winter) but now it failed with BSD after prime95 3 hours!
 
I think I might know now of why my overclock bundles isn't stable as before. Because of different bios firmware version as I did updated to bios firmware F12 but I think I brought the ocuk bundles last time was F7 bios ? I can't remember which bios version could be F7 or F9. I think Rich might know which bios version does work on my overclock stable.
 
I had now finally stable my pc after 14 hours prime95 blend test with 191x21 with 4Ghz. It took me almost 3 hours to get it right setting without cause any BSD.

Here is my stable 4Ghz overclock using F12 (firmware in bios):

Linx stable:

good times

thats some pretty good clocking BD

i knew you had it in you :p

its good to see you tested using a range of stress tools
no point just testing linpack if you get blue screen death in other things!
 
lovely stuff, my C0 is not quite up to the job. with the 4GHz settings BSOD on windows splash screen, with Vcore = 1.3V BSOD instananeously when starting a Prime95 blend!
 
woah woah

if you are using a C0 chip you may want to tone it down a bit

maybe try 181X20

then maybe look at starting your voltage around 1.38v

then work down from there until you get low voltage.

some C0 chips do 4GHz+

mine did 4.2 on air so it is possible, you just tend to need more votlage for them as a rule of thumb :)
 
:) no worries! yeah knocked it down to 181x and going again. Besides disabling hyperthreading and reducing Vcore, are there any other settings in the BIOS that are effective at reducing temps?

Many thanks Rich :) I had now got 2 x Akasa Viper fans (1900rpm) in a push-pull and add another 1 x Akasa Viper fan at the rear exhaust as three fans is control with PWM with a special cable 'Akasa AK-CB002 PWM Fan Splitter Cable' from ocuk as it was silent when using overclocking. And during overclocking, the max temp for 4.2Ghz @ 1.30vcore (bios) is 77C, 74C, 76C, 73C and I am very happy with it overall.

I love this fans: http://www.overclockers.co.uk/showproduct.php?prodid=FG-059-AK as I did order it last week.

I can't wait to get my hand on i7 970 (6 cores / 12 threads) in 2012.
