Decided to push my chip a little harder. Previous stability test @ 3.6. I will never use this speed but it's nice to know it will run @ 3.8.
Q6600 G0 L726A850.
FSB 424x9 = 3816 Mhz
Vcore 1.5250 Bios/ Actual 1.4960
Prime95 Large FFT 3 hours 20 min.
Ambient temp 22 deg c.
Antec 900 case with all fans set to medium speed.

CROSSG, i see that ur not running small fft's, should run those. at 3.75 i can run blend, but my computer restarts within mins with small fft's, i can bench at 3.75 but small fft's are not stable, they are only stable at 3.6, and my temps are right now 57c on the hottest core on water, those temps would rise if u run small fft's, i hooked my radiator on the back of the case and my temps went down like crazy, more than 10c. first i had it in my lian-li on the bottom, and my load temps at 3.6 were 69c. now 57c.

sorry i see that ur running large fft's but for me small ffts stress the most, and produce most heat. well here is a screenshot at 3.6 prime on water. made a big difference putting the radiator on back of my pc, about 10-13c

Highest highest 3dmark- q6600 benched at 3.75

crossfire hd 2900 858/900.

at 3.6 24/7 setup i got 18259- and at 3.75 i got the following.

Yeah Small FFT raise the temp about 2 -4 deg but I am on air and not looking to max out my temp or overheat my chip. If I drop the vcore two notches it will fail in Prime large FFT in about an hour . ;)

Ok still working, here is 3.7 after 8 hrs small ffts.

Got my Q6600 GO today:up:
Start testing on air for now(as soon as i can find a good air cooler in stock:( ).
Finally switching to water next month. I will post results as soon as i`m up and running.

i got mine stable at 3.6 and temps are 56c on the highest core under load with small fft's. i can bench at 3.75, but prime shuts off anything higher than 3.6. i am pretty happy with 24/7 at 3.6 but my chip does 3.6 at only 1.39vcore loaded, and i dont know why it shuts off at anything higher, i think my board might be limiting me.

my 3dmark 24/7 stable

sorry not my board, i meant my computer, i run small fft's at 3.6 forever with 1.39vocre loaded vcore or mch voltage didnt help any, but anything higher with in about 10 mins of prime the computer just shuts off. i can bench at 3.75 though but cant prime anything higher than 3.6

A reboot is normally caused by needing more vcore I found.
Could be temps if its shutting down/off, whats the PWM/CPU temps?

cpu temps are in the screenshot above on this page as a proof, but they are are 56-57c under load, the pwm area is in the high 60's low 70's

That is truly amazing. At not that much vcore and VERY low temps for air. Nice freakin chip.

Thanks. I do have a really high flow fan on the ultra 120 extreme but I am still quite happy. It is on the bench and ambient is about 25c. Vcore in bios is set to 1.4625 I believe. I'll try higher tomorrow.

those are good results, what is ur room temp, mine is 20-22c on average, its weird here, 2 days this week were hot as hell and now the temps are in the 70's the highest, freeking weird temps by the beach.

I'm trying to work out if 'A' or 'B' chips are better or worse than eachother. Most people seem to have 'A', but is that because there are more of them around or that they clock better?

I just received a L726B (you see why I worry?), pack date 08/21/07 so it's very fresh lol. Waiting for an Asus P5K3 Deluxe, got 2GB CellShock DDR3 1800 8-7-6-21 already in the bag. Need some silicon grease and conformal coating, this is going under the Vapo LS. Might give it a run on the stock HS before that tho.

Can't seem to get 3.8 with small fft's. Went up to 1.525 vcore in the bios which turned out to be 1.4800 under load. I don't think the extra vcore is worth the extra 100mhz so I will probably run 3.7 as my 24/7 clock. Now I just need to get my ram dialed in and I think I will call it good.

I find my 720B chip pretty amazing. MP05-LE water cooled also Vmoded 8800GTX in the loop set in bios 1.5675v benching 4130mhz with no problems 3dmark06

Bumped my FSB a touch and added a notch of Vcore from this test
Q6600 G0: L726A850. 428 x 9 = 3852 Mhz. 1.5350 vcore (bios) 1.5040 prime load.
Small FFT 2 hrs +. Still running
Ambient temp 22 deg c.

Nice crossg and temps still look good. Maybe I'll give mine another go when it cools down a bit here. What are your other voltage settings?

Thanks.:) I should have stated that this speed is not useable for me becuase of the fluctuating ambients, it's 22 deg now but by this afternon it will probably be around 25 deg and that temp will probably push my core temp over 70.:( I think 3.6 is going to be my 24/7 clock.

Anyways my voltages are:
PCIE Freq: 101
Vcore: Bios 1.5375v / 1.5040v Load
Clock Over-charging Mode: Auto ( haven't a clue what this does)
CPU Voltage reference : 0.63x
CPU PLL Voltage: 1.60v
Dram Voltage: 2.25v
FSB Termination Voltage:1.40
Northbridge Voltage: 1.55v
North bridge Voltage reference: 0.67x
Southbridge Voltage:1.20v

Dram Static read control: Disabled
Transaction booster: Disabled
CPU Voltage Damper: Enabled.
All the other usual stuff disabled.
Going to switch over to Vista and see if I can get 3.6 stable with the same settings as I use in XP. About 20 more proccesses running in Vista.:rolleyes:

ur right crossg, i got mine running at 3.6 24/7 and i am quite comforstable with c1e enabled and idling at 2400 and under load 3.6, i really dont need 3.6ghz when i am browsing the net and watching movies, lol, full load temps are 57c with small fft's
