No im not happy, the system froze at stock volts 3.8 Ghz in Prime 95, and it wont do 2000 Mhz ram :mad:

Trying 1.225v 3.8 Ghz, 190 BCLK, 1900 Mhz Cas 7 ram.
 
First successful OC with no crash - 4 Ghz @ 1.3v! (Might manage lower, havnt tested that yet).

My I7 920 needed 1.34v for 4 Ghz.

Update - 1.275v @ 4 Ghz working.

Now 1.25v @ 4 Ghz is working (ram speed down to 1600 Mhz Cas 6).

The ram was causing the crashes before, the CPU is great :)

4GHz is a piece of cake on Gulftown..... 4GHz is nothing to the Gulftowns.

Indeed, my initial attempts were foiled by trying to OC my ram at the same time.

Stock voltage, 4 Ghz, Prime 95 + SuperPi passed at the same time:

Such an improvement already over needing 1.34v for 4 Ghz on my I7 920 :)

I'm going to be keeping my R3E + I7 980 till they go obsolete.

or until the ivy chip comes out :P...

good job

No. Ivybridge will be capped to 4 cores on 1155, and X79 costs too much.

Ive already been tempted with sandybridge but I want to downgrade my mobo.

The gains would be small, I used S939 for almost 6 years until the E8400, and then the I7 920.

3.8? er so what? lol

I only got it today, I was ocing at stock volts. This thing is awesome compared to my previous chis, and as for sandybridge CPUs, LOL Z68.

I would have to have a Rampage 4 extreme / formula and nothing less, but that stuff is way too expensive, so instead I got this :)
 
Hmmm, so my ram will run safely at 1866 Mhz 7-8-7-24 @ 1.65v at 133 BCLK, but I cant seem to get those settings stable while also OCing the CPU!
 
Ok, heres all the frequencies it will work at:

4 Ghz on stock volts (<70 degrees)
4.333 Ghz on 1.325v (<85 degrees)
4.5 Ghz on 1.38v (one core reached 100 degrees, my Antec Kuhler H2O 620 isnt enough).

All stable at 180 BCLK and 1800 Mhz ram @ 7-8-7-24-1T :)

4.333 is fast enough, if I ever want to push it to 4.4 Ghz+ I will need a better cooler.

Eventually, not right now, I gotta buy one of the Adata 120 Gb SSDs first.

4.560 Ghz unstable at 1.4v, so 4.5 Ghz @ 1.38v was the highest it went (I dont want to go over 1.4v) - Prime 95 and Super Pi were running for over 30 mins before one core reached 100 and its worker stopped.
 
Ah, yea that wouldnt be any better than my 620 since its currently using two silent Xigamatec fans, but the air coolers are massive and bulky.

.... What about that diamond thermal paste, will it make any difference over my MX3?
