Overclocking an i7 920

[CJBronco II]

Motherboard - GA-EX58-UD3R

RAM = http://www.compusa.com/applications/...7&sku=C13-6152

I have 3 sticks of those running tripple channel.


Bios Settings.

CPU Clock Ratio 20x
CPU Frequency 4.00GHz (200x20)
QPI Clock Ratio Auto (I had it set to x36 then changed it to Auto and it has made a difference so far)
QPI Link Speed 7.2GHz
Uncore Clock Ratio x17
Uncore Frequency 3400MHz

BCLK Frequency 200
System Memory Multiplier 8.0

CPU VCore 1.325
QPI/Vtt Volts 1.315
IOH Core 1.30 (This setting I never changed until yesterday and I think it made a difference. This setting was mentioned in the article from Voicy but not in the guide provided by Gigabyte)
DRAM Volts 1.66v

CAS - somehow by default it was at 8/20 I changed it to 8/24 and tried 9/24


As of right now, I ran Prime95 for 2 hours and no errors, I also set Prime95 to test with 1 thread while setting the memory to 6100MBs and ran for over an hour with no errors.

I then Ran LinX with the default settings of 16331 for the problem size and 2048 for the memory but increased it to run 10 times and ran with no errors.. This was the program I was getting errors on earlier this week.

I then ran Memtest in windows. I ran 2 instances at the same time using 1500MB of RAM in each instance and it ran for over 200% coverage with no errors.

I ran Fraps, GPU-Z to record highest temps, Real Temps to record max temps and played MWII for well over an hour and no crashes at all.


Everything seem fine and dandy until yesterday, not even 4 rounds deep into MWII MP, it locks up, no BSOD, no hard crash like before, but a lock up with this loud repetitive sound. I had to do a hard boot and then I ran those tests again.

This time Prime95 had one out of 8 workers stopped. it ran 6 tests in 11 minutes with 1 error.. Ran 2 different tests in OCCT and they passed, then tried Prime again and the same worker stopped.

These are the 2 sources I used to help with the OC

The gigabyte link has a "grab a guide"


Can anyone tell me if my MoBo isn't meant to have the RAM OC'd? is it the IMC arguing with the RAM frequency? Does the CPU and the RAM not getting along to cause these lockups and BSODs before?

Please advise... I am at a loss.

Stability test with a game.

Over the past 2-3yrs Unreal Tournament III has developed into my most trusted app that tells me if i am stable or not...

EDIT: contrary to my sig

Yeah, i was using MWII while running a bunch of monitoring type apps in the background, it ran stable Sunday, but Monday it locked up.

Now Rig 2, what RAM are you running in it?

I'm running 12gb of G.Skill F3-12800CL9-2GBNQ memory (2gb x 6)
So im not sure how much any of my settings will help, but here they are.
I'm running i7 920 @ 4.2ghz (with turbo / 4ghz without)
And im running a GA-X58A-UD3R , so some settings may be different, but ya never know it might help.

Mem set manually at 9-9-9-24 (yours looks it should be same timings)
I'm running a little extra voltage on memory due to vdroop and running with all six slots filled.

And you also have a better Motherboard than I.. You have the X58 6 DIMMs, I have the EX58 with 4 DIMMS which will never make sense to me because X58 is triple channel..

And you already have 1600MHz based RAM at stock.. Mine is 1333Mhz based at stock trying to OC to 1600MHz..

However this helps out alot. Thanks for posting this.

I got 3 Elpida Hyper ICs running in it. A DDR3 2k kit but I never took the time to get them stable beyond 1400Mhz. They have a bad history rap and it seems mine are doin ok but at very low speeds and voltages.. Using 1.54v @ around 1100Mhz CL8

I see.. thanks for the info... looks like I'm forced to ride with 4.0/1200Mhz CL@8
