I knew I should have held back that last run till the last minute, or better yet done a run at -3c. But it just didn't seem fair at the time (but sounds like a good idea now )

Viking, if you are still awake, you can relax. It's 5 or 6 degrees warmer here than when I did the last run, and getting warmer. I've been trying, but it's not gonna happen. I dropped the nb multi, tried lower volts, and higher (up to 1.632 ) but it just needed more cold.

Congrats!

Unless it starts cooling off

Hi Folks,

I know I've been kind of quiet lately, just haven't had any killer results to report...

I see the Vcore some of you folks are running and my chip just doesn't seem to like anything much higher than 1.5v, believe me, I'VE TRIED.

I've been on my "Ugly Water" the last few days and have never seen temps over 50c, so I'm pretty sure it's not a temp problem.
It's not all a bad thing, this chip will do 4Ghz easy (@1.475) which makes it a killer air chip but I was hoping for a little more with water and voltage...

I'm certainly NOT complaining!
I'll play with the IMC a little more tonight, maybe that will help me get more on the core without adding v's....

I did notice my Mobo NB and PWM section getting REALLY hot since I went to water, so I added an Antec "Spot Cool" over the PWM heatsink tonight.

I'd really like to get 4.1/2.7 stable. I think it's doable...

If I get it I'll post some screenies.

BTW: I'm doing this on ambient w/water, I got tired of shivering (hehe).

I fried my 940 @ 1.42 a few nights ago, so be careful what you ask for my friend.

These parts are relatively low leakage and efficient. So they are working well on H20 & agressive air and are showing nice scaling in the 35C to -20C range and beyond. I am suprised by the (relative) consistency and goodness of the results. They are not particularly voltage tollerant without substantially decreasing temperature. Phenom II scales like none before with cold, but I offer some perspective, we can (sometimes) get to 1.8V at -260C. So between 50C/1.35V and -260C/1.8V you've got a voltage tollerance line, more or less, and certainly always on the edge of failure.

People seem to think the Crosshair has an edge driving core frequency. Also, I think big radiators and airflow help. But you already know this.

Thx for nice fight....it was very hard...both cpus clocked about same i think, i hade very hard to make the 4140mhz run i think it crashed about 5 times, so i did one @ 4130mhz first that one crashed first also... but when i did it a second time i succes and after that i did it on 4140mhz but fail @ 4150mhz.

Edit : Added Movie to the 4100mhz screens...didnt make any @ 4140mhz crashed to many times.

My results are great!... I'm somewhat of a wimp compared to some folks on here. I've been playing with Phenoms since the 9500's...
It seems like they've always had a temp limit of ~53c, and every chip has had it's own personality.... But hey you have to push it a little...
To my credit, I haven't popped one yet (Mobo's are a different story)...

I'm probably not really extreme enough for this site, but I hear ya Simon...
I don't really push too hard, I look for stability first and work up to max clocks slowly. This chip still ROCKS...

I really want to play with exteme cold, but I don't have a POT or a TEC and leaving the window open when it's 32f outside just ain't working for me...

[Grinder]

Viking:

At 4144, I could get about 10 minutes in. I suspect that a little more cold would have done the trick.

Check out loc.o's post in the c3 results thread. There's an extremely cold, fast 0942fpmw

Daveburt:

I can relate to the "shivering" remark.
1. Light woodstove
2. Close office door
3. Open window
4. Place PC on the edge
5. Put on extra clothing
6. Keep hands in pockets, to retain ability to operate mouse

64NOMIS:

I should add that there's a fine line between being bold/aggressive, and stupidity. I probably crossed it, and just got lucky that I didn't fry my chip! At least I have my 550 to fall back on, and the latest 790xt-ud4p bios would let me disable that pesky weak core. (I didn't want those grapes anyway )

What I'd like is 4 ghz and a bit and high nb for day to day use, without freezing or having to wear earplugs That, and fast graphics too!

Thanks for encouraging us to push the envelope.

Simon is this the same 940 you used in this thread?? http://www.xtremesystems.org/forums/...d.php?t=215894

Blast from the past

[theoldtimer]

I’m still hoping for some cooler temps but until then I guess I may as well keep benching with the ones Mother Nature is dealing.

[FlanK3r]

I am so unhappy that i can not to time post some result with C3 (where is my C3 so long? )....

oldtimer: impressive, 18 000+ in Cinebench, omg, what cooling? Watter or window air?

I need one of those boards like yesterday......

[Zeus]

4.0GHz Prime stable seems to come far too easy on these C3 cpu's, i felt proud doing that on my C2 cpu but now everybody seem to get it.

Itching to try a C3...

[Norz]

Damn,i also need the 790 FXTA-UD5,looks greate. My 790X DS4 is killed by death it seems...Rip

...still waiting for mine C3..

I also got 4ghz prime stable on c2

c3 I did 4.3ghz prime with ice water. its a great cpu

[FlanK3r]

i want something better, 890FXT-UD6

[Raiderman]

Shouldnt be too long and the other manufacturers should be popping out the same specs.

[equinox1]

i've had a little fun over the last few days, not ice sculpture crazy like chew but it's been fun.












but alas my poor crosshairIII has given up the ghost, something just went POOF!!!!!!!!. my 965 seems to be ok though, i tryed it in my foxconn board and it works. thats what happens when you mix drinking beer and overclocking. no fear. new board on the way to continue on.

oh yeah, theoldtimer nice 3d06 and vantage but i still got ya.

[theoldtimer]

Great numbers equinox1, I’m impressed! Sorry to hear about the crosshair III dying, what were benching BTW?
Well I don’t know if I can catch you but I hope to at least be competitive maybe in January.

oldtimer: impressive, 18 000+ in Cinebench, omg, what cooling? Watter or window air?

Thanks FlanK3r, I’m using liquid cooling. I posted (post#98 of this thread) a photo of my cooling setup. The radiator isn’t that big 169 sq/ins and it is mounted outside as shown in the photo. I’m encouraged by how well the cooling has worked so far and expect better results as winter sets in although I may need to add another pump.

[64NOMIS]

Grinder & Lastviking,

What were your DRAM frequencies and timings for your 4.118 and 4.140 runs respectively?

Amazingly close results. Great competition.

[Titan7171]

just finished some more testing with new bios helped me push to 4.5ghz 3dm06, 4.5ghz superpi1m, 4.5ghz wprime, and a 4.4ghz cinebench 64. This cpu kicks ass!

Remember Im running DDR2 and Im on M3a79-T Deluxe.....not on one of those new fangled mobos

My Corsair pc1066 5-5-5-X 2.1v did not like prime95 @ that speed dont know if it are IMC in the Phenom II 965BE i have run them 24/7 with my 940BE on that speed before...but didnt work in Prime96 with 965BE for me. I know i did have same trouble before with me 940BE when i did use Dfi board... got random blue screens @ 1066 5-5-5-X. Phenom II have some trouble with memmorys...got friends some have trouble with DDR3 also. Dont know if IMC/L2 voltage have some inpact on memmory stabilty also. I did have 2x1024mb OCZ pc1200 sticks before also and i could not run them @ rated speed also... crashed in 3dmark2006.

I think my memmory was sett to pc800 and auto becuse all the crashes with the sticks @ rated speeds.

I with i could run rated speed but its dont work....to much money to buy sticks and see whats work best to...looks like some sticks works beter with Phenom II than anothers.

Looks like it was DD2 vs DDR3 (Lastviking - Grinder)

What difference a revision makes. Really impressive.

But I must ask, since you've got the extra juice how would do on the thread theme test - prime95?

Hey thanks......to you that is. Without you alot of us wouldnt have had the chance to do this or even organized something like this into one thread


Im out of ice and I went for these other tests since I didnt have a chance to run them last time.

Highest prime so far is 4.3ghz



heres the original post

Ill be trying for new 30 minute prime and highest vantage in the next day or 2

[Lastviking]

Titan7171 see that you run DDR2 also. What voltage is your sticks rated to @ 1066 5-5-5 ?

2.1v or 1.8v?

Im pushing 2.1 through them and they are rated at 2.1v

i have too DDR2 (Kingston hyper-X) for 1066 MHz 5-5-5-15-24 its ok 2V, for max full stable OC (busspeed 206) my RAMs 1098MHz its OK 2.1V.
