Retail Q9650 Overclocking Thread

[papatsonis]

L847C144 VID:1.125 , this moment , linx-ing 3200@1volt (I dont need to rape it from start.. :P) , but having relatively high temps (despite my Ultra 120X) ,~ 48-52 C , im hoping for 3.6@24/7 1.1v or less.. if possible

[nkresho]

^ I wish you luck. I'm really happy with my L837c. You beat my vid too.

[papatsonis]

thnx man, and i was worried when i saw pack date in the box 7/8/09 and the cpu 847.What cooling u use? air or wc?


EDIT: pardon my blindness :p , i just read above u use WC

[andressergio]

You have to increase the CPU Voltage.

I've got the same problem with my chip perfect stable for 100 passes in LinX but I can't pass Prime95 for 8 hours. Increasing the CPU Voltage makes it stable and I don't have these MACHINE_CHECK_EXCEPTION BSOD anymore.

The only explanation I've got so far for this behaviour is that with lower CPU Voltage you can't give your CPU the amount of watts it need to run stable for several hours.

That's what I think is the problem.

True...that i told nkresho on his first post, i can pass linx IBT and long blend will fail eventually.

Cheers and Congrats for that chip mate

[OC Nub]

Same for my 9550, can pass LinX with 1.29vcore-500x8.5 but needs 1.312v to pass a long prime blend run.

nkresho: I am curious to see your temps once you get up to 4400mhz and above. At that point I cannot run LinX/IBT anymore and have to stick with blend due to temps, the vid is 1.175v for my L847C037 9650. The second rad should help a lot, keep posting.

[nkresho]

I'l keep you guys informed, don't worry.

I'm 5 hours in at 4200 and it's doing fine. And yes, I did have to add a voltage bump over IBT. I'm up to 1.216v in cpuz, from 1.200.

I'll take a screen shot if she makes it to 8, then I'm off to the land of 4300.

[ReverendMaynard]

could you take a screen shot like above only using a new version of CPUZ instead of v1.45?

Nice chip nkresho.
Good luck in 4.3 land.

mate what Room Ambient you have on those tests ? you are on AC ? or normal room temp ?

Just to have a reference

Cheers

[nkresho]

No ac, it's only getting up to about 24c outdoors here this time of year. Windows are open.

Temp measured at the front of the case is currently 26.7c, prime blend is getting the hottest core up to 59c in realtemp (other cores are at 56c). Water temp is at 31.7c in my reservoir.

I just ordered a hk 3.0 waterblock about an hour ago, should be here by the end of the week... it will replace my current dtek fuzion v2.

I plan on putting my other res in tonight whenever UPS comes. I'll get more temp results at this clockspeed to compare to then too.



Ok, finally done with 4203mhz. I got blend stable with 1.24375v bios and 1.216 in cpu-Z

[OC Nub]

I want to see what a second rad does for your temps, I am as high as I can go at 4500mhz because of heat in blend. I will add another if it does well.

Thanks andressergio.

This chip is to good for my ASUS Rampage Formula board.

Here's what I've got so far with these nice G.SKILL F2-9600CL5D-4GBPI memory and my Q9650. The ASUS Rampage Formula isn't the best board for OverClocking these Q9650 CPU's but it's a nice board to clock these G.SKILL sticks.

[flesheatinvirus]

I thought about that myself though I am running a PA 120.3 just for my 9650 which is overkill already. I just grabbed another 9550 yesterday from Microcenter for 159.00 and its a 1.150 vid which is nice, 3850mhz at 1.22v so far is not a problem even on this P5QC board.

Can you post a pic of realtemp showing min and max vid?

[papatsonis]

[OC Nub]

DAMN!!! That is insane.

[andressergio]

I think now you should remove you AMD avatar

impressive vid enjoy it and play

Watch out for the speed boost!

Nice

ty guys! , the only restraining factor seems my
X38-DQ6 (or... my inability to tweak it.. :P) as my first attempts to find a stable high fsb setting had poor results , partly due to my 4x1gb sticks. above ~415(5:6 - ram 498) starts asking for much vMCH in non linear "response" (1:1 setting is obviously much more demanding in terms of vMCH :S)

that board sure does suk i couldnt get 4 stix past 900 with a dual core on dq6
and would bsod past 500fsb and totaly corrupt windows in 2 days past 500fsb

guys it is safe to use LLC on the UD3R for 24/7 4GHz @ 1.23v?

I'd say it is.

It hasn't hurt my CPU, neither has 1.7V.

[nkresho]

Here's the first full run with the second radiator installed. Temps went down just a little bit. Water temps are lower by 2-3c, but cpu temps seem down by only about 1c. I guess I wasn't fully using all the radiator cooling potential I already had. No problem though, I'm sure i'll use it eventually.



Also, here's the log where I added the rad.
