Yes. Most definitely. =)

I'm trying to get to the 4GHz goal and I have ran into a ram problem, I can boot into windows but as soon as I start prime i get the 124 error. The problem is I have the timings backed off and the RAM underclocked(using the 1333 setting) and the voltage maxed and the command rate set to n2 but its still unstable.


Is the Corsair not up to the increase in the baseclock?

Never mind got it to work right after I hit post


Just passed the first Prime95 test at the 4GHz, but the xms3 is crap for overclocking.
My next goal is to get to the 4.5 mark then maybe 5

I accidentally left the ram on the 1600 setting as I took the baseclock up. When I first set the ram to the manufacture specs I was only getting 4 out of the 6 GBs I had to back off the timings to the last stick to read. To get the OC stable I had to put the ram on 1333 setting.

I played BFBC2 for about 5 hours today with the processor on 1.28v and I still have the 1066 and 800 MHz settings for the ram, so I think I can get it to 4.5 but he 5GHz may be a little challenging

hey guys, what should I try for 4.2ghz HT on?

ive used the quick and dirty settings (4ghz) of this thread and raised the vcore to 1.325v

I just wanna be stable enough to run wprime

my i7 does 3.8ghz w/ HT @ 1.25v, 4ghz w/ HT @ 1.3v....

OK cool.. Well ws just thinking i haven't seen a 920 hit over 4.7 on water plus with only 1600 ram your less likely.. But never say never.. Let us know when you hit 4.5 stable as i'd be interested in your settings and/or may be in a position to offer some advice.. i'm using h50 which is basicalyl like top end air and maxing at 4.45, trying to get 4.5.. water cooling does provide more headroom though..

Again though i'd 'almost' bet my PC you won't hit 5Ghz completely stable with your specs.. i'll give you kudos for trying though

Hey fill in the template and post yoru settings and i'm happy to offer some advice mate.. You 'should' be able to hit 4.2 so yeah post away and we'll have a look.

p.s. also fill in your system template as it will help determine some of the finer detail mate.
Cheers!

i7 920 D0 (new one, pretty voltage hungry)
OCZ Platinum 6Gb DDR3 1600
Corsair H50

geez, I cant even stabilize 4.15ghz, keep getting BSODs 124
tried QPI volts from 1.3-1.362..

- 5.400GT = 20x
- 5.800GT = 22x
- 6.400GT = 24x
From what I've found the 920 can't have the QPI changed. I can't even find a SPI Frequency in my BIOS. All I can find is the QPI Link Speed, which is in GHz and twice the numbers listed above.

Here is my MO manual. M.I.T. start on page 37.

I'm interested in what the noise level you are getting from the H-50 pump. I am considering this cooler but am also working toward an almost silent set-up. Currently, I am using a Kaze fan controller to keep all of my fans, including the cpu fan to just about a silent level. Thanks.
