Q6600 G0 on air @ 3.51 ghz

[orion456]

Here is my work computer: Q6600 G0 stable on air at 3.51 ghz 1.4v (droops to 1.31v) fsb=390, 965P-DS3 v3.3, Ultra 6400 memory, Thermalright SI-128 w/120mm panaflo fan exhausting into a duct. The temperatures are pretty amazing, 47c core and 33c surface.

It will boot at 3.6 ghz but is not stable on load at 1.45 volts.

What's up with Core #2?

Are you running two Prime 95's?

Those temps are pretty nice, what's the ambient temps over there?
Nice OC you got though :)

[OneArmedScissor]

Awesome!

Those cores fluctuate around, core #2 was 43c just now. I'm using prime95 and OCCT. Prime gives me some numbers to watch because OCCT just tells you failed or passing.

Ambient is an air conditioned 24c.

Stable 3 hours so far.

[hUMANbEATbOX]

are you running just one instance of p95? if so, you should have one for each core, or 2 copies of orthos, one for each pair of cores.

OCCT does 4 cores, and I added Prime95 so I had something to watch, so that's 5 cores, which is more than enough for the quad I think. :) As you can see, all 4 cores are fully occupied doing good works.

Air results! woo hoo! Looking pretty awesome. :D :drool:

I dunno, I can't get out of this hole... P5N32-E SLI.

Voltages
NB 1.5, SB 1.55, CPUVTT 1.55 (jumps to 1.62-1.67), Mem 2.2, 1.2VHT-1.4

are those good voltages? dunno what to do =(, is my new bios 1203 unstable???

I don't know anything about that board. Its the Nividia chip set so maybe that is a problem. Post your system, memory, PSU, etc. and maybe someone who has that board can give some advice. Have guys overclocked that board well or have you seen postings on it?

Do you have active cooling for the north bridge?

If you lower your multi, can you OC higher on the FSB? If so, then its probably the chip that is holding you back. If not, then the board, memory, or you need more active cooling around the CPU.

Here's some settings I found for a fsb 425 overclock:

wow...hell of an OC on air dude.

[orion456]

wow...hell of an OC on air dude.

Yeah its awesome actually for a quad. I think it can do 3.6 ghz if I give some voltage to the NB but I didn't have time to play with it too much. It was instantly stable at 3.2 on stock voltage, then needed 1.35v for 3.4 and 1.4v for 3.51. After that 1.45v didn't help 3.6 to be stable under load. All the other voltages were on auto, so there is room to play some.

[treatmentx]

Yeah, I held the multi at 8, now I'm at 425, no problem at all, I didn't know what voltage so I even went up to 1.55v and it's idling at 38C/35C/36C/36C, and load at 58C/57C/56C/56C.

So what do you suggest? Should I just keep trying to push FSB at multi-8, and leave everything at auto? my nb auto'd to 1.55v, i have the optional fan on the North and South Bridge, I "think" it's at 37C right now, shown on PC Probe, NVMonitor, Temp2 on Speedfan.

[inkfx]

My fingers are tingling. I sooo want one of these quads. It would do wonders for my F@H score. Good luck with the chip dude and again, very nice clocks for that quad.

[Stevie G]

Very nice OC there :santa:

I'm going to be happy with around 3.2

In your sig there is mention of H20, you haven't run the quad under water cooloing yet?

[Phrenetical]

those results are scaring the pants of my credit card :drool:

[orion456]

In your sig there is mention of H20, you haven't run the quad under water cooloing yet?

I have two G0 quads I bought as soon as the price went down. One for home and one for work. My home quad is doing 3.6 on water (Asus p5k dlx), work is 3.51 on air (Gigabyte 965P-ds3).

What's amazing is water is only doing 0.1 ghz more and the temps on air are so low I can hardly feel any heat coming out the fan exhaust. I measured the temperature of the exhaust and it was 30c (room temp 25c). Speedfan is showing the surface temperature to be 31c...THAT'S A QUAD @ 3.2 GHZ ON AIR!! It was stable over night @ 3.5 ghz and not much hotter. If this keeps on going we won't need water for the next generation of CPUs.

So you are at 3.4 ghz now (Congrats! :beer: ) and @ 425 x 16 = pc6800, does that exceed your memory speed of pc6400? If so, then you are blocked on the memory side now?

What cpu cooler are you using?
I'm seeing about 60-65C load on my q6700 @ 350x10, and I'm running this with Ultra-120 Extreme @ 1.45V (bios reading, set to 1.525V).
I tried lapping the heatsink, but never quite made it very flat - it still has a bit of convex curvature. What's your cpu voltage?

Thermalright SI-128, 120mm Panaflo M1-BX high air flow fan on an exhaust duct so no hot air goes into the case.

Voltage = 1.4v set in bios, 1.32v actual.

By 60-65c do you mean core voltage or CPU surface voltage? My core temperature is less than 50c.

the 965 ds3's looove NB voltage. I jumped mine and thats what let me break 500fsb with the E6300.

Rock on 965P. :beer: :attn:

This is promising for me! Xeon 3210 results in a week or so :)

If so, then you are blocked on the memory side now?that's quite a mild memory overclock, even with less than desirable memory. could ddr2 800 memory really limit overclocking at 425mhz?
the 965 ds3's looove NB voltage. I jumped mine and thats what let me break 500fsb with the E6300. any idea if that applies to P35 DS3s too? I would be a little hesitant to up the NB voltage on any motherboard, since I've already had one close call

not that i doubt you, but i can only see the p95 window, and the temps for the cores. can't see the others doing work.

but i do take your word. :)

that is a super nice OC man, making me jealous. ::beer:

[orion456]

My 2nd pick shows SpeedFan and all 4 cores on full load.

[Maverick0984]

I think he means that we are trusting they are under full load, nothing in the screenshot really proves full load.

[orion456]

How about all those litte green bars on the SpeedFan shot and beside them it says 100.

Ah, didn't notice there was a second image, maybe he was thinking the same.

Fan1 is funny, ONE MILLION RPM.

[GTengineer]

very nice Orion!

could I ask for a 1M superpi at those speeds? I am interested to see what the added cache in those babies can do compared to my E4300.

[ToeKneeATX]

very nice oc! my b3 only does 3.3ghz atm, i wish i got one of those g0's. good job man.

[treatmentx]

I'm so envious, you have no idea... stupid 680i board... =( still reading around, but it looks like I have to SOLDER my board for a stupid vmod.... too rich for my blood.

You could always tape down a piece of copper wire :santa:

[orion456]

Yep, SpeedFan can't seem to read my Gigabyte DS3 or p5k fans properly anymore. If I slow the fans down, then it reads correctly.

[hUMANbEATbOX]

Ah, didn't notice there was a second image, maybe he was thinking the same.

oh no, i saw the second image. :)

i just have never in my life ever used speedfan. i've seen lots of pics of it, showing temps, but i've never looked for the load in them.

BUT, like i said before, orions word is good enough for me. ;) i would have believed him without the bars. but now i know where that info is in speedfan for the future. :)

cheers orion, keep on clockin'. :beer:

[richklein]

Orion - What do you think of the Asus PK5 board? Do you like it? I was curious, does it have 5 SATA ports + 1 ESATA? I am a little confused on how many it has.

I am looking for a simple air OC (q6600 + air + some mobo, maybe this one). I know YMMV but how do you like the Asus mobo with this P35 chipset?

Thanks,
Rich

[MadMan007]

I believe it has 6 SATA ports off the Southbridge and 2 eSATA ports off the JMicron controller. I kind of wish they had one of those JMicrons internal like on the P5B-dlx, it was nice for hooking up a SATA optical drive.

[Brolloks]

Great OC Orion, hope my Q6600 from NCIX will be a G0 as well!

[pscout]

any idea if that applies to P35 DS3s too? I would be a little hesitant to up the NB voltage on any motherboard, since I've already had one close call

I had to max the nb v on my p35-ds3r and bump fsb to +2 to fold stable at 370x9.

[shirker]

I had to max the nb v on my p35-ds3r and bump fsb to +2 to fold stable at 370x9.did you get a chance to test out how far the fsb could go with a maximum NB voltage? I'm having serious doubts now as to whether I should get a p35-ds3p for my Q6600...I absolutely need high FSB clocks, and I've heard the Abit IP35 Pro really shines in that regard
also, how are the NB temps on the p35-ds3r?

[pscout]

Orion ... there is a quad version of p95 that i now use. 1 button click to run 4 threads.

I tried it at 450x8 but it wasn't folding stable with < 1.4V and over that i didn't bother trying much since temps were getting to high for it to be stable folding.

It runs stable at 425x8.

Never bothered with a 7 multi since i know i wouldn't like its folding performance there - not enuf cpu clock.
