*Official Retail G0 Q6600 Overclocking Thread*

[[XC] 4X4N]

What voltage do you have at 3.5? Your temps seem way high even for high vcore. My temps really start to climb over about 1.45 vcore.

[Avman]

Sometimes it's the FSB limit on the chip homie.

Yeah, but I was able to run at 9x446 at 1.44v and I'm 3d06 and gaming stable at 1.47real (I have neither the patience nor the time for long periods of Prime - 5 mins and then its game time) and previous experience with C2D's would suggest it's probably got another couple of hunderd MHZs if I can give it enough volts. I'm cooling limited right now as my vapo is stock with 0 mods for the quad load - I ran my last Xeon 3060 at 1.68v and 4365mhz and this Quads low voltage behaviour matches what that chip did. We'll see in a few weeks - If I can swing a new mobo I'll need something Penryn ready anyway

here's my data from a previous post in this thread:
-------------
Here's my data so far:
L724A760
VID = 1.2875V

3.2GHz w/ +50mV - 8 hrs stable
3.3GHz w/ +62.5mv - 2 hrs prime stable.
3.4Ghz w/ +125mv - 8 hrs stable - 35° idle, 70° load 8 hrs
3.5GHz w/ +175mV - 6 mins prime crash... temps 75°-80°
3.5GHz w/ +200mV - 5 mins prime stable, no crash... temps ran away so i shut down (~90°C)
3.6 w/+200mV - 1 core fails prime 1-2mins in... i don't think i'll be going past 3.6 or +200mV unless i get better cooling.
---------------

primed last night @ 3420MHz for 8+ hours w/ C1E enabled - all stable. Temps now hover around 63,64,65°C.

edit: priming right now, remotely, via VNC while at work using clkgen. 30 mins stable so far at 383 x 9 = 3447 w/+125mV (1.4125V in bios, 1.36V under load read by smart guardian)

How many B3's have you seen @ 3600-4000mhz on air? Not only do they OC better, they are a lot cooler. Some people don't believe that they are actually cooler, they think it's an issue that needs to be addressed with core temp or whatever. Some people say ad 15c to the temps and that would be the correct temp. My radiator fans are blowing towards me and i can tell you the G0's are cooler. With my B3 the air was so warm it was hard to even sit next to it. With the G0 i hardly notice the air.

Looks like I will find out...it will be nice to use something other than phase for a change. Can you point me to a post showing a stable 3.6 and 4.0 on air?

Its one thing to bench in the 3.6 to 4.0 range on air and something entirely different to run stable at 3.6 to 4.0 on air.

Also what week were the chips in the overclock's you were referencing and do you know the vCore and temps reported...better yet just point me to the link.

Thanks again....

This one was phase ...

Impressed but shocked at the vCore and temps. On my B3 at that vCore I would have been very hot.

http://www.xtremesystems.org/forums/...0&postcount=50

Very impressed!!!! But running two orthos instances still only stresses 2 cores...

impressed but no prime...

Im still a bit skeptical but will see for myself on Friday and thanks for all the links I owe you one!!

[GripS]

Let me know if you find one(3.6ghz+ stable on air). From what i have seen the high clocks on air usually are under unreal circumstances like an unusually cold room or an air conditioner pointed at an open bench setup. I'm not talking benches or 2 hours prime stable either. Talking 8 hours prime stable on air in a room that is approx 65-70F.

[nugzo]

Im still a bit skeptical but will see for myself on Friday and thanks for all the links I owe you one!!

are you sure thats phase?


TEST SETUP:

* Q6600 G0 L727Axxx
* XFX 680i SLI Motherboard
* 2GB Corsair PC10000 DDR2 RAM
* PCI Geforce MX400 GFX Card
* 60GB IDE Drive
* Corsair HX620 PSU >> 620W
* Thermaltake Big Typhoon air cooler
* Windows XP Pro Lite

maybe i didn't read far enough, i just went by what OP posted. Anyway, good luck on yours. My first 2 sucked, my second 2 are completely stable at 3700mhz on water. 1.45v 55-60c loaded.

[nugzo]

Anybody tried one of theses G0's on the MSI P6N diamond 680i? I'll have the MSI tomorrow and will post results.

[GripS]

Bah.... Damn work restrictions i can't see pics in that post from Dinos22. Does it show reasonable temps on an 8+ hour prime load? I'll check when i get home.

Must not be reading this thread then or you missed my post.

This ran & still running folding at home 24/7 stable for the past 4 days.
I've seen times when passing prime or Orthos for 24hrs that folding wouldn't run stable.
So if you want a real test use folding for a stability test, if it can fold its stable.
http://www.xtremesystems.org/forums/...&postcount=614

Also Orthos can fully stress all 4 cores if you know how to to set it up.

http://www.xtremesystems.org/forums/...&postcount=529

Here is a shot after 32 hours full load & the paste "AS5" has settled some.

[GripS]

Hmmmm..... OK. If a system can pass prime95 but fail folding then you should have no problem posting 8 hours of prime95 then right?

Not one of the links posted shows 8 hours prime stable on 'normal' air cooling. I don't feel so bad about my modest clock anymore. I guess what one person considers stable isn't necessarily stable for another. To each his own.

Please don't take this as an argument. I'm not trying to start anything. sdumper asked for proof of 3.6-4.0 STABLE on air cooling. I have yet to see the proof from the links provided.

[Avman]

Stable is an opinion. Speaking only for myself, I don't care if I can't do more than a minute of priming, as long as I don't have any crashes (random or otherwise) during gaming and my pc otherwise runs solidly.

IMHO if it is not 8 hour SP95 stable then it is a joke because your just waiting to corrupt your os

ive seen a couple of dudes who claim stable but cant post any prime 95 shots because it just isnt stable so it crashes

bench stable is diffrent though most of my benches are verry unstable but aslong as i can run the bench mark im happy

my 24/7 settings are always ~ 3 day F@H stable

[whitebrow]

My VID is 1.2875V. All I've really tried is increasing the voltage, but I can't even get into windows at 3GHz. I was going to play with it more tonight but I'm putting it off until tomorrow afternoon. I'm fairly new to this, I just built the rig initially in January. Are there other things I can try? My plan is to take note of all the Bios settings, try getting it at 6x333 and higher if I can, and then put it into the P35-DS3R.

I know that my ram is stable at 4-4-3-4 375MHz (750) 2.1V, and I've gotten into windows with the FSB up near 500 with an E6400. This is not with the new 1601 bios though. I don't believe I can downgrade any more than the version previous to this one without losing G0 support.

To update this, I did place the processor into my brother's computer to test it. He has a P35-DS3R and an AC7Pro. It booted right up at 333x9, and 375x8, I didn't want to push it a lot farther cause I don't know what his ram can do. Both were with 1.3125V.

I checked the settings on mine (P5B-E), I have the FSB termination voltage @ Auto, C1E disabled, CPUID disabled, Vanderpool enabled, CPU TM enabled, Execute Bit enabled, and PECI enabled. I am running 310x9 @ 1.3V in bios.

I'm going to get on the phone with Asus tomorrow to get their take. I'm hoping they're going to tell me that this is something I can fix with a Bios update, otherwise I'll be jumping on the X38 train in a few months...

Any other thoughts?

[billdavis]

ill be jumping on that train also the asus p35 is a good mobo but sata sucks!

[TheWolf]

Well if I wanted to waste 8 hours of my folding time I would redo the test with Orthos & this time take screen shots. I don't use prime95 much, have never like its layout or the way you can't tell how long it been running as easy as Orthos. Like I said I have had it fail F@H after running more than 8hrs of prime95 or Orthos so I don't waste a screen shot on those two very often except in just to show what the temps run at after 15 or 20 mins. of there load.

I have a Xeon X3210 coming & I just moved the Q6600 over to my AB9 QuadGT for testing is another reason. I had hoped for a better OC in the GT but at this point looks like 9x390 is the max stable OC. Only more testing & maybe a backwards flash to beta 13.b04 will help get more. The GT is on final 15 bios at the moment.

Once the X3210 has been tested & I find witch CPU I like the best for the IP35 Pro IF its the Q6600 G0 then I'll put it back, then I may do the 8 hour test just so you can maybe be happy with my results. Not that I really care. lol

[billdavis]

that is good!

some people mistake bench stable with F@H/Prime stable

that is odd f@h failed when p95 is 8+
did the ambient temp change? maby a littel more v core and youll have it

the QuadGT is running the 1066 strap all the time that is why it is limiting the overclock on the Q6600...you are getting exactly what i got on the QuadGT with my Q6600 B3....it's faster in superPI than my current IP35 Pro...now, overall system performance on IP35 Pro is now on par with the QuadGT results....i used PCMark 2005 to compare the two boards.

the only way i know of is increase Vcore...BUT...that is based on the other voltages are sufficient to support ram and chipset function.

make sure your ram is operating ina 1:1 ratio

A little more tweaking/voltage fix the problem, this was at the 3.6 OC in the above pic. I hit up to 3.990 with this cpu played with 3.8 & 3.7 but was tiered & never got a stable setting prime or Orthos wise. I'm happy for now with 3.6 & may try for more later on.

I'll have to re-check but the 1333 bus I'm sure was added for the GT in one of the later beta bios. So someone said. There is no added option in bios to manually select the 1333 bus. I asked in our mod section at the Abit Forum if the 1333 bus option could be added as selectable option/unhidden. No answer from the bios team yet or Abit. I'll have to double check were I got the 1333 bus info from. Can't seem to find the post at this time.

Going by your sig & memory timing I would say loosen the ram timing to 5-5-5-15 "stay at 1:1" to take it out of the picture & then test to see if it is stable.
You didn't give us much info to go on so that's about all the help I can give at this time.

[TheWolf]

I had heard this before bios 14, but here is the info.

BIOS release V14 for AB9 QuadGT

Release information:

[ENGLISH]

1. Support FSB1333 CPUs
2. BIOS compiled date: 06/21/2007

I didn't do much testing with 14 because of some reported problem with that bios. Hmm maybe I should since the problem was to do with ICH8R AHCI function & fixed in 15. You would think the 1333 was carried over into the 15 bios, but could have been part of the problem with 14 & removed from 15. hmmm Got me thinking...

BIOS release V15 for AB9 QuadGT

Release information:

[ENGLISH]

1. The ICH8R AHCI function now works as intended.
2. BIOS compiled date: 07/18/2007

[Gunlance]

I actually backflashed from bios 15 to 14 and it didn't improve anything. Just food for thought.
