i7 950 MAX Overclock on air

[Nanometer]

Thanks to the great help of a thermalright ultra extreme 120; I can get 4.4 ghz at 1.377 vcore at the voltmeter. Is this a bad 24/7 voltage? Load temps are below 70c

[nascasho]

Hell no. Keep pushing! I wish I had D0 when I see topics like this!

Your limit is 85C.

[Nanometer]

you serious? Id probably have to up the volts to at least 1.4v

At the meter it reads 1.400 exactly on idle
Under load the meter reads 1.377.

70c is Coretemp, not that crappy asus Probe My coolest core is the last core which is always 4 or 5 degrees cooler.

And Rig Pic M8

Nice 24/7 Profile

[nascasho]

Whoa, core temp?! Just make sure none of your cores for your 950 pass 85C and you're good. And you mean core temp not socket temp (CPU) right?

[Nanometer]

The cover is on the floor, a few adjustments because I just got the Ultra 120 this evening. It barely fits in this case, but there's room for it. I also broke the front led, i have to buy another from radio shack.. i was sleeving the cables heh








Yes, this is coretemp. The thermalright has fantastic contact on the CPU. If you notice the string, that's my mounting system for the fans. Decided I didn't like thermalrights bracket. BTW this is 45 prime stable, at this stage I feel that's more then enough.

[nascasho]

Whoa, nice case! And at that clock, you probably won't bottleneck a GPU until the year 2029... or until the T1000's come out... err I mean... pretend I never typed that. :/

[TheCarLessDriven]

Wow, thats a crazy clock for air. Hope I can do something like that when I get my i7.

[Solarfall]

very nice clocks with such "low" voltages.. it takes me 1.43v to get my D0 "stable" at 4.5ghz with air (true black) with water i can go much higher

[Nanometer]

Now I'm getting random of BSOD since i was fooling around with it... great...

I'll test later to see if its another ram issue or a bclock issue.

[Leeghoofd]

Try to disable LLC, haven't had one BSOD since

Hope you can fix that BSOD, its already a great OC mate! Keep tunin'.

[ReverendMaynard]

dump turbo mode and go for a higher bclk, turbo with the 950's is really buggy and can cause some pretty erratic stability. That's the cause of your BSOD's mate. Two lads on my team confirmed it.

[Nanometer]

It's definitely the BUS or the RAM. I turned down my multi to 20 and I still get crashes. I might be testing ram sticks too, I just lowered my bus speed and still BSOD. ROTF... not really. My first set of reapers died within one week. This set survived for one week more if that's the case.. FML

[Nanometer]

what the is LLC?


Testing stick one, fine so far and no BSOD. 10 minutes prime. If there's a dead stick It should fail memtest which Ill do later.

Sticks seem to be testing fine so far.... Next test is single stick test at 4.5

[Nanometer]

Can't even boot on default settings now.. ram checks out OK. I can't even boot into safe mode, ill try a repair install....

[Leeghoofd]

LOAD LINE CALIBRATION, also try to loosen Back to Back Cas Delay to eg 6-8

[Nanometer]

I saw people running this board with 10 B2B delay or higher. I'll check out load line calibration, right now it's dissabled. ive just got home and installed vista... again.. it got screwed up. might have something to do with the pci e freq

[nascasho]

I feel guilty for telling you to push it harder...

[Nanometer]

lmao dont. im all good right now. primed 200 x 15 for 2 hours and thats set. now im at 200 x 22 and it's loading the highest core at 84C, no errors yet so i tihnk i will lower the voltage more. 4.4 might be the max for air because of temperature.. if i had water im very confident i could have 4.6 ghz out of this chip
volts for 4.4 ghz right now im using 1.40V so it could be a little high. well it is high.. but more testing to come..

[nascasho]

Cool, post em'!

[Leeghoofd]

try to loose the even multi then things will be (hopefully ) rockstable from there on. Can you install the full 12 Gb, mine is pretty close with the TRUE with plastic mount, the kingston ram fits, the Blades not

[Nanometer]

I'll post more later Yes, everything fits, even 6 sticks of RAM. But you cannot use thermalrights bracket or it will not fit. The sticks basically touch the fan, but I don't care. The big question is how much performance will I lose going back to 6 sticks when my RMA comes back in.. I might just sell the RMA set and keep these if I'm pleased with the low timing results..

The even multiplier doesn't seem to be an issue. In that case If i do loose it, I will bump it up to 23 for an even 4.6... though unlikely, don't hold your breath. Nobody has an air cooled SFF i7 at 4.6ghz

I take that back, 4.6 ghz is possible, but only if its cold outside with the window open.. more to come stay tuned. screen shots tomorrow and better pictures.

For the record, LOAD LINE CALIBRATION WAS VERY IMPORTANT! Night and Day difference of stability.

Glad it worked, too bad you need to put in way more volts but it's more stable. I had several BSOD's while reviewing the mobo, even at idle or when just surfing and posting comments on forums like this. Tried a zillion of voltages, ram settings, 3 different ram kits, no go...Disabling LLC helped on my Gene II.

Keep us posted how it goes... You got a nice 950 there, mine needs way more volts, but I'm happy at 3.8 at 1.14Vcore... Minesweeper is done in under 1 sec :p

sorry for the disbelieve but would you show us a screenie at full load 4.4@ 1.37v with temps below 70c on air
Unless of course HT is disable
