*Official Retail G0 Q6600 Overclocking Thread*

[atlxkevinx]

Hey everyone, just got my water-cooling done. Now the fun begins.

So I am kind of new to the Q6600 but all I did was 400x9@3.6 and set the vcore to 1.3825 in bios, 1:1 ratio, 4-4-4-15@800Mhz for ram @ 2.150 and it fails prime95 in about 10min but temps ~45c, is this temp good for WC? also Should i give it more vcore? Do I need to change any settings besides the vcore? how about the cpu vvt?

[Zucker2k]

I hate Prime not showing the elapsed time without you stop it. You need to calculate it.

It does show; you'll need to look at the iterations... towards the end.

Orthos is Prime95 code, exactly. It is the enhanced GUI of Prime95.

Actually, Orthos has not been updated for a long time, so I don't think this statement is correct.

So far with my chip i'm managing 3.0 on stock volts with loadline calibration enabled.....cpu-z reports 1.192v as well as asus probe, VID for this particular cpu is 1.225 for reference.......this is with a stock cooler mind you........temps are between 50-60c loaded. I will continue to push it on stock volts till prime crashes.......

figured i'd update, apparently i had voltage set @ 1.125 oops...set it to 1.225 and vdroop is minimal it appears cpu-z reports 1.208 and pc probe reports 1.21..........currently priming at 3330 still on stock volts and stock HS

On a side note temps seemed to have gotten better with loadline calibration on and the actual vcore applied to the cpu.........

Thanks for the hint on iterations. Yep, that way, Prime95 is easier to use as it is natively 4 cores compatible.

Otherwise, the algorithm in the mersene number calculation wasn't changed since the begining. Just solving bugs in some instances...

Anyway, just for all people to remember. At 400 FSB and above, the NB is a major limit on many boards. So, a test with OCCT in RAM mode is vital for your stability testing (not really related to the CPU though). Blend doesn't reveal the NB limitations well

Anyway, thanks for the Prime95 hint

Anyone seen this batch of Q6600 Before?
Batch No. L740A630 S-Spec: SLACR.

All i can tell is, its a G0 from the SLACR

Hey Guys !!

I don't know where to place this question, but if anyone is interested on selling a good Q6600 G0 batch that makes at least 3,6 with less than 1,4 vcore bios i will buy it. Here in Uruguay are terrible expensive and I only had the chance to bought one, mine does 3,6 with 1,475. I've seen some wonderful L737B and others...

So if anyone is planing to sell to go for a penryn or something please tell me. I will pay it as new.

Thank you very much
Sergio

Recently came from Amd 6400+/Asus Crosshair

Now have Q6600 + Asus P5E (Pencil Mod)

Changed fsb from 267 to 333 to make it QX6850 Speeds

Auto voltage was 1.35V but is stable so far at 1.25V

My question how low could i go prime95 stable?

Should i raise other Volts to compensate for lower Vcore?

[KTE]

P95 stresses cores more=>higher temps, drawing at least 12W more in my testings than others have (not incl. the 'ol CPU Burn and TAT). Usually caught a failure when others failed so I use it as one of my initial stability tests (many more after). I would use any other had they proved just as good or better.

My 1.2375VID 1.2V stock Q6600 G0 L739A has been rigored under stress today.
Like the versions I had before, too hot at stock, needs noisy high fanspeeds or expensive cooling to keep decent load temps at even stock. At the fanspeeds I like it topped 64C at stock with 22C ambient outside of the case. Imagine 30C inside the case, or heck, summer.

Right now, I'm priming 1.28V idle/1.264 load 3.3GHz on air with one fan at high speed. Seems solid, I doubt it'll fail: 2hr10m passed 50C, 50C, 54C, 54C so far.

L738A9, 1.2375VID
Bleh...I've got to lap my Ultima 90. There's a square full of scratches right in the middle of the heatsink albeit fine scratches. It wasn't there when I first opened it, meh. Clocked it to 3.6 @ 1.375v but it was too hot. So, sticking at 3.2 @ 1.25v for now. Getting 38-40 idle and 60-64 on load.

[disruptfam]

My L737B does 3,6GHz @ 1,288V, 3,8GHz @ 1,39V and 4GHz at 1,50V

My max valid on air in a 21 degrees room is 4,15GHz :thumb:

wow nice chip..

whats the whole exact batch number and week please

[KTE]

Yeah S1mon-, this G0 does 1.280V/1,264 idle/load) 3.6GHz but what is P95 8hr stable for that chip, any tests?

[disruptfam]

i'm looking @ the q6600 go's in aus are i keep finding this

bx80562 q6600 is that the batch number?

if so is it any good? no google results

cheeer mate

i came across this cpu on ebay... 3.1ghz stock volts look good or average to you guys??
Thinking about purchasing it..

http://cgi.ebay.com.au/Lapped-Intel-...QQcmdZViewItem

vid: 1.3125

[chew*]

mine does 3.350 on stock.......for comparison....vid 1.225 prime stable on stock hs.......

[disruptfam]

so its a pretty average chip?

[chew*]

so its a pretty average chip?

I would say its not that special......

[disruptfam]

cheers mate i'll see if i can find a better one..

thanks

[GutterZ]

Todays testing with new P30 bios. I installed the Evga p30 bios cause the
p31 was acting weird . It seems to be alot better! On the p31 I had my vcore at 1.56 v core to get this OC to do prime, now its at 1.36 v core. All seems well so far with this clock an bios. My vcore goes up when I load the cpu according to cpuz with this new bios
Ive had this up to 475 x 9 boots at 1.50v but not even 3dmo6 stable till 1.62v an nowhere near prime95. But with the p30 bios Ive yet to try to see if that changed also.

I have that one at 3.7 24/7 stable @ 1.47v so far will play with it withing the next week or so to see if I can squeeze a bit more from it

I had a little time to mess around with my processor tonight. The stepping is in my sig.

What 1-3hr load temps do people using a TRU[E] get at 3600MHz (various volts) at near 22-30C ambient?

I'd be every interested, thanks.

[disruptfam]

thanks simon loads temps look a lil high what are you using to cool that?

also awesome chip bei fei!!!!

i found a L739B897 is this batch any good?

cheers

Never saw this before for some reason but thanks S1mon. That's very good actually.
Idle Vcc will be near the 1.312V mark?

Those temps are exact same as mine at 3405MHz 1.312V 5hrs P95 with only one fan Zalman 9700 with 6C higher case ambient than yours. 1.28V gets a little lower temps stable.

There's a problem with my setup. Whatever Vcc above 1.28V I set in BIOS, it keeps dropping to 1.28V under load, 1.3, 1.32, 134, 1.385. That didn't happen with the E6750/E6850 I tried last. 3.45G is around max stable with 1.28V idle/1.264V load, more MHz and Core3 will fail instantly whilst the others don't till at least 3.605G that I tested. But volts for 3.6G stable seem high, maybe past 1.4V actual. I'll try it soon but I'm scared of the crappy temps and power I'm expecting.
