Overclocking i7 920 on a Gigabyte X58-UD5?

Recommended Posts

Hi.

I was wondering if anybody could help me OC my CPU to somewhere around 3.6GHz (I am using a Zalman 9900 cooler, for reference).

I don't really know much about this stuff and I'm trying to get some more fps in the CPU-intensive beast that is ARMA II.

 

Any help appreciated! :)

 

My general hardware specs (if needed);

 

Gigabyte GA-EX58-UD5

Intel Core i7 920 d0

6gb Corsair Dominator 1600MHz

HIS HD4870 IceQ4+

 

Hurr durr, just found this old thread...

I'll try nesquick's thing, if I run into trouble I'll post back. :)

install EasyTune6 from the CD and then click on the 2 or 3 button and the PC will restart and give you the OC you need with one click....usually that works fairly well

Dinos- thats if you like software controlling things :/

 

thats for 3.2ghz btw rebirth, you will need to set BCLK to 171 and make sure your ram is close to its rated speeds.

Is it? CPU-Z said 3500MHz. :/

 

I ran OCCT and lasted 5 mins 33, so I upped the voltage to 1.28, and lasted 18 mins 26.

I asked Nukejockey about it and he suggested 1.3v... I tried that, lasted 7 mins, and my PC reset.

 

I put it back to 1.25 for now while I ask for suggestions.

 

I'll try that BCLK 171 now and do a test and note it here.

 

Okay... bluescreened 5 mins into the test.

Restarted, tried to post... bluescreened again.

Restarted, changed BCLK to 167.

 

These settings last 5 mins in OCCT.

 

What should I do?

did you lower your ram speed?

 

also lower the QPI speed to x36 and up the vtt a tad.

 

edit: for clarification I looked up a pic of the bios so change the following:

 

1. cpu clock ratio to 21x

2. qpi link speed to x36

3. BCLK to 171

4. uncore to about 32-3400mhz

5. memory multiplier to 8x

6. XMP to diabled

7. dram timings to 8-8-8-24 2n

8. CPU vcore leave it at 1.25v that should be more than enough for 3.6ghz

9. qpi/vtt to 1.3v

10. Dram voltage to 1.6v

11. load line calibration enabled

 

see how you go with that :)

 

also grab a copy of linx it will find problems faster than occt, prime95 ect, 20 passes on LinX and its stable :)

Okay, I did all those exact settings, except for the CPU clock ratio @ 21.

 

Apparently the max is 20.

 

Made it to 20 passes in 8 mins on Linx... Did I do it all right?!

EDIT: Lol, just opened OCCT... apparently my CPU is underclocked from stock by around 40%.

 

What should I do?

Seems to be going good now with NukeJockey's help.

It seems my BIOS disabled BCLK all by itself... so it was running at stock speeds.

Enabled it again and set it to 171.

 

Just passed 20 times in LinX with no errors, 6 mins 30. :)

Just did 20 mins in OCCT with no issues before manually stopping it, too.

Thanks for the help!

what vcore are you running BTW? im worried you set it to something really high.

Stock.

 

His ram might be at 1.66 though, but it is rated for 1.65v at 8-8-8-24.

Vcore is 1.25 as you said.

RAM is 1.6 flat, from memory... though I'd have to double check on the RAM.
