boo.. your OC makes my 965 EE seem like a stunning waste of money :P
i need 1.6vcore to get it stable @ 4.4ghz

though.. the vapochill isn't powerful enough. Because it has to battle to cancel the heat out (vs taking the heat off the chip) the ever increasing temps (over 4.4ghz) are pushed to unstable levels. In about 4 "test" cycles on prime it becomes to hot and crashes.
The temps do drop VERY fast when there is a light load.
So i'm pretty sure i can use higher every day OC than a full load OC - as when the hell am i going to be break out 4 (or 8) threads running for a few min non-stop. *shrug*

still pisses me off i should have picked up a 940

It is lol!

But reading through these forums would have told you that

Anything but a 920 is unfortunately a stunning waste of money...just the XE chip is a stunning waste of money^2.

And I own a 940, so I'm not biased. Just telling it like it is...

On and on a different note, after a while now my cold boot problem is back. I'm rather pissed about it. I have no idea why it is back, nothing changed on my system at all, but it is definitely back.

Three days in a row now the system does not power on after I shut it down at night. Instead it starts all the fans, displays DET DRAM and then it hangs. To get it to boot I have to hold the power button down, wait until it shuts down, then press it again, reload my BIOS settings, and voila, I am rock solid stable again.

The system is memtest, memtest hci, Arena, Prime, and LinX (Linpack) stable...

At first I thought it had to do with 1001 BIOS, but now I noticed that even downgrading the BIOS does nothing to alleviate the problem. I have not experienced a single cold boot since I stopped using X.M.P. profiles about 1.5 months ago...that is until now.

Totally weird.

I hope you can get your boot issues worked out Dejah . Keep tweaking and you'll find your 940's sweetspot .
I've personally seen the 965 topple both the 920 and the 940 clocked at the same ghz . All on the same board (Evga x 58) . SOMETIMES ITS LUCK OF THE DRAW on each cpu. I've also seen the 940 with its 22 multi at some great clocks. 4.4 , 4.5ghz...At my local lan cafe one guy has his 940 on AIR at 4.4ghz with triple Sli and HT ENABLED. So it is possible to get some great clocks out of all 3 cpu's.. Most of the time a bad overclock is user error or bad components .
I have clocked both the 920 and the 940 on the same board. I may have had a off batch cpu but I couldnt get the 920 stable past 3.8ghz . Pulled out the 920 and popped in the 940 , kept the same voltages and BAM . CLOCKED IT TO 4.115 GHZ with ht and 4.3 without . Vantage and prime95 stable.(its the setup I'm on now).
I've built 4 Corei7 systems so far 2 with the 920 ...2 with the 940. I'm probably going to get scorned here for saying this but both 940's clocked higher and was more stable with 3-12gigs of ram than either of the 920's . Luck I guess . Thats was enough for me to see to get my own 940. Glad I did.. AND damn glad I chose the Asus over the EVGA.
HOPEFULLY a future bios will fix the unstablility with HIGH OVERCLOCKS wile using HT. I could run this all day but why treat my cpu like LAST YEARS Model?

Topple in what way? Architecturally, these processors are IDENTICAL to the last detail. It is impossible that a 965 runs the same clocks better than a 940 or for that matter a 920. If clocked higher, that's a different story. Also, a lot of users do not realize that not every board will let them run Turbo permanently on like Gigabyte does so during a benchmark a CPU may downclock but you will never know. On some boards you need to disable TDP limit, on others (like P6T/R2E) you are plain out of luck for now.

Besides, looks like all of us will get a double whammy soon with the arrival of the D0 stepping. Every current i7 looks like it is being phased out and replaced by supposedly better overclocking parts. The 940 and 965 seem to be going EOL and are to be replaced by 950 and 975. Personally I think this is a bunch of bull, but whatever. Especially bad for 940 and 965 owners though as we paid so much more for supposedly better parts and basically got relabeled 920s.

Anyway, this is a R2E thread so we should not be discussing i7 processors here.

I would say 100% right there.

Although, don't give up heart dejanh, this board has plenty of weird stuff going on, I have not had cold boot as issue yet, but I have had lots of silly stuff going on, which just doesn't happen usually, stick with it buddy, I feel better times coming

Were all here for each other buddy

same problem here but it only occurs after total power off.

From the various posts I've read it's starting to sound like a PSU or maybe bad motherboard issue. If it's the PSU it's very typical to be inconsistent.

The only boot prob I had was a failure to startup after a warm boot from Vista64. I could reproduce this problem 100% consistently. More accurately, the system wasn't shutting down properly to begin with (indicated by continuously burning ROG light and BIOS LED after shutdown). My mobo never had a prob from initial power-on.

The above has been resolved in the latest 1104 BIOS.

Word to the wise. Make sure you have written down all of your OC Profiles as bios 1104 wipes them all out. Wish I knew that before hand as I had several set up.

[Helli]

yepp, the TDP Limit is gone - for me. :-)

Now i can do 21x210 (4,4GHz) Vcore 1,55 with my i7 920 and Load on all
8 cores. With Bios 1001 and lower the Multi decreases to 20x if i start
Prime95.

Ouch!

I'll wait for now I think.

Thanks for the heads up.

I also have a Vapochill and found that it was having a tough time. Then I had a closer look at the shell I was using and found that it was hitting the cpu mounting bracket and causing the cold plate to not make good contact with the cpu.
Did some minor mods to the mounting shell and now the vapochill keeps the temps down.

Hope that helps.
