OverClocking i7 920 2.67 GHz On Gigabyte EX58-UD3R

[-Flamez]

Hello everyone i am new to overclocking well sort of :\ last few days ive followed this guide http://www.tomshardware.com/forum/253365-29-core-overclocking-guide
and had no success my pc would'nt boot and multiple errors causing the system to revert back to deafult bios settings... NOTE this was before i got my new Zalman
CNPS9900A installed i also noticed a few options not in my BIOS from this guide so all the help would be GREAT..

To start off i'll post my full computer specs so everyone has an idea of the exact hardware/bios/mobo/cooler ect...

Currently all my bios settings are at optamized defaults so i'm looking for a guide that will show me how to overclock my specific machine i am new to this but i have a decent knowledge of BIOS.
I want to get an overclock at 4GHz as iv'e read alot that people can get this result stable...

All the help would be great..


Thank's

Here's a really good guide for overclocking your Core i7 920, it's also good for newbies.
http://www.tomshardware.com/forum/253365-29-core-overclocking-guide

As for hitting 4GHz on air, the Zalman CNPS9900A isn't particularly a particularly beefy cooler, I'd say it's a pretty good replacement for a stock cooler, cooler by 10C-17C approximately.

wow thanks mate i'll have a go at this guide, as for cooling as long as my cpu doesnt reach higher than 70 -80 c under full load ill be fine right?

 

[-Flamez]

okay i need help after doing Step Three
Change the uncore multiplier to the lowest setting.

i save and reboot.... then my comp keeps restarting itself over and over and now i cant get into anything no BIOS... all i did was chnge the uncore multiplier to the lowest then changed the base clock up by 10 Mhz hit save...

arrgghhhh

looks like i have to take the battery out to clear the CMOS....

 

[Lmeow]

Hmm, strange. I never encountered that problem. Resetting the CMOS seems like the way to go.

You don't have to set any mutlipliers to lowest to overclock it, you just have to set it to lowest to find your max base clock IIRC. As for temps, i7 core temps can reach 100C, but really it's best to keep it below 75C or at most 80C.

Good luck, I'll post tomorrow morning, I'm very sleepy lol.

 

[-Flamez]

haha okay ive done some test's and found it doesnt like the uncore multiplier frequency changed at all wel anyway setting it to x36 'lowest' and i dont have time to try it higher as i have to pull out my GPU's each time to reset my cmos -.-

Things ive found that are working
*Change the memory mhz to the lowest posible ratio
*Chang the "QPI link speed" to the lowest possible setting

So afr so good also ive disabled all power saving and turbo boost tech C1E---C3/C6/C7 State----EIST ALL DISABLED.. i ran a test by increasing my base clock to 143 mhz 'increased by 10,hz' booted fine into windows ect... Volts1.264 2.86 GHz
Next Increased base clock again to -153 Mhz result 1.312 V @ 3.06GHz

thats as far as i went because i got worried about the voltage going up to high as i never changed any voltage YET...

Wish me luck trial and error

and i dont have time to try it higher as i have to pull out my GPU's each time to reset my cmos -.-

That sounds strange. Gigabyte motherboards can usually automatically reset the BIOS to a bootable configuration.

Very strange... anyway back on topic the GUides here for overclocking are not good man i DO NOT recommend anyone use that i7 920 OC guide...

The best one is here http://www.xbitlabs.com/articles/cpu/display/core-i7-920-overclocking_11.html

Great Guide my overclock is stable at 3.7 GHz very VERY happy with the results form this.....

going to run a 24hr stability test overnight later too really make sure 100% my OC was a success

anyone know how to change the ddr voltage on a gigabyte motherboard or is that the same thing as the DRAM voltage
