Depends on the batch and oc ability. Start at $200 and go north if its really good chip.Quote:

Batch # L828A446 - same as andressergio and nkreshno Q9650, I believe.

I have nkresho's old chip and it is a L847C batch, so not quite the same one as you however you have a lower VID, mine is 1.15.Quote:

Finally got 4.5Ghz with 8Gb of Tridents chugging away @ 1200Mhz. Can run Prime 95 blend (128k - 4048k fft) all day with 6.8Gb of ram but small fft keeps freezing up on me. Amazing chip, only need 1.4V BIOS for 4.5Ghz so far.
I am thinking I should push CCPU Clock Drive to 900mv in ACC, because currently its 800mv.

You might want to raise your vtt up a notch, the 1.32 vtt setting doesnt work right its really the same voltage as the 1.30 setting.
Already tried that, Priming with 900mV drive strength at 1.39375 Vcore, 1.32 vtt. If 1.32 vtt doesn't work then what does 1.34vtt set the voltage to, 1.32V actual?Quote:

Ok, thanks for the info :)Quote:

Nearing on total 4.5Ghz stability on air. ACC does help a little bit, at least from my experience with my older Q9650, 800 > 900mv was equivalent of bumping vcore one notch.

That's a lovely low vcore for that speed - nice chip! You gonna bench it or at least try for higher fsb?

Good clock oldcomer! I'm tempted to have another stab with my old Q9650 - snag is I only have the USB3P to run it on. I'm sure it'll be great for benching pi32m but don't know if this board can push as well as my UD3P rev1.6 (which now has another home). I guess trying won't harm it although it'll be on air (with lots of big fans) if I do. I think I need a pot and some LN2, but sounds too expensive for what it's worth....
Only had it for a week so far but definitely going to push it to the limit. Once I get water, say 4.8Ghz 24/7 stable :DQuote:

Trying to push the chip to 4.55 but I keep getting restart / freeze issues. Should I increase MCH Clock Skew to 100ps from 50ps?
Try upping the cpu skew 50ps, that was what solved that problem for me at those speeds.
:( too early for that turns out. Just need to tinker with Cpu Termination and Mch Core / Ref values a bit more.Quote:

Probably limited by my MB (P35)
can someone help me get my q9650 stable @ 3.8ghz??
My mobo is an asus x38 ddr3 maximus extreme! I run my cpu 24/7 @ 3.6ghz 400x9 with NB temp at 32C idle but 3.8ghz makes my NB hot reaches 50C (altough cooled with an antec spot cool)
to get the mobo stable at 3.8ghz i have to pump 1.7+volts to my NB less than that it is unstable in gaming. FSB VTT is at 1.4v, CPU PPL 1.6v, CPU core 1.3v and Loadline Calibartion enabled is a must to eliminate vdroop!!
I use the corsair h70 with push/pull stock fans to cool my cpu :) As for the TIM i use the AC MX4!

Your v core is way too low, and if you have the north bridge any higher than 1.58 you risk motherboard damage, your pll is not proper either I think I used 1.65 sometimes more, try also please list what timings your using on the ram, and just to be honest you should be using a q9650 on a p45 board to get its full potential out. I hope some of my input help as I've seen the worst of the batches do better than what you've provided you'll need to increase your v core to 1.42 if it works from there lower the v core by two or three intervals until it isn't stable.
so you mean i need to set vcore to 1.42 for 3.8GHZ? isn`t cpu pll 1.65v too much for 45nm cpu? as for my northbridge it needs 1.7volts less than this it is unstable! My ddr3 ram is corsair DHX 1600mhz 9-9-9-24 stock timings 1.8v

Something you should know 2.0 vdram is considered suicide on air , secondly you should consider I have stabilized many systems and set fires to enough systems to know what's safe and what's damaging. Your northbridge/mch is too high I don't even use that much for liquid nitrogen. Secondly you must read this whole section pages 1 to the end or don't bother overlooking unless you have the money to throw around or you could damage everything you have with the voltages your using....
Wanted to add something else yorkfield based chips can die to termination being 1.38 or higher your playing in danger atm..
well 2.0v on this ram is ok according to corsair (ramguy) but 2.1v is the absolute maximum! as for my x38 chipset it is well known that it needs juice to stay stable and i saw people running this mobo on 1.7v red zone volts in the bios and according to intel spec this chipset temp limit is 90C and i never reached that much temp. the most i reach is 50c (cooled with antec spot cool) with with 1.7v when you say you dont even use that much voltage for LN i dont beleive you sorry remember x38 get hot soon and needs volts at high fsb :)
You could very well be right since its x38 and all of us with q9650 or the extreme version used p45 ud3p motherboards to achieve great clocks. But honestly you really should go to p 45 if your having trouble with 425 fsb or greater . My qx9650 which I sold for its full retail cost because of what it could do, used ud3p mobo and could do 530 fsb with low termination and low volts ran very cool :) maybe you should consider it.
