So i did some test and used 1.20VTT .785cpu ref and .84mch (relation) ref and problem solved....

But sometimes it happens that i have to load optimized defaults and re load the OC profile ass prime will fail. I know that the giga has some problems on stored profiles, got to load 2 times or it will leave the divider on AUTO...but for all above not any trouble on x9 multi.

Cheers Sergio

Oh btw F10f bios on post with ALT + F12 lets you get rid of F10e backup
bios, it will flash current version to the backup (Thanks to OC NUB and KHIMO for the solution :up::up::up:)

Very nice run Sergio.:up:

Ok, here's what I have so far. I primed at 4203 this morning and got it stable for a 4 hour screen shot.

I came back around the 5 hour mark to take another and found an empty desktop with the little "your computer has recovered from a ...blah blah... message"

Looking at the cores, I bet it's a gtlref issue as 0 and 2 are off by the same number of tests as 1 and 3...

Am I correct in saying that the cpu ref is 0.797 divided by 1.22 = 65.33% and the nb reference is 0.812 divided by 1.260 = 64.44% I was used to my asus where ther is a ref for 0/2 and anotehr for 1/3??? So IIRC, theres a single gtl ref for the fsb and another single gtl ref for the nb????


Still working on getting this speed blend stable before I go on to the big time... 4400, 4500 beyond. lol

I'll probably do a remount tomorrow as well, as core 1 is always 3-4c higher than the others, which are all within 1-2c of eachother. Might be a bug too.

My second rad (mcr220) comes tomorrow and I have the whole day off, so I'll post more when I have it. I'll try to make a mini worklog thingy for adding a 120x2 to the bottom of a cosmos-s, I'll put it in the water section. If I get ambitious, i might even do a before-after temp comparison of some IBT runs. We'll see though, rad is coming UPS and that guy usually taked until 5pm to get me my stuff.

^^^ Your chip, sir, is simply an engineering feat. Take good care of that chip. :up: Absolutely incredible!

I agree with Zucker2k, that is a great chip. Best I have seen.:up:

^Thanks guys. It is a golden one, I agree. I'm really happy with my results so far. I'll try to keep impressing you, I promise.

And... yeah... I'll do my best to keep her under 65c... Priming anyway. Glad it's almost winter.

No, it's "The One." A real devil of a chip.... scratch that, the "devil chip." :ROTF: :clap:

Anyway, the 9550s are clocking so well that I truly expected the 9650s to perform way better with the latter batches. It seems you really got lucky with your chip, a true gem. :up:

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.:shrug:

I'm taking it slow with this OC as I'm terrified of destroying the bios! Due to bad experianced with 4 previous 680i chipset boards and my old E8500!!! Loads of RMA's!! And about 6 weeks! Anyways - I booted at 360*9 with vcore at 1.185 (VID 1.175v) I booted fine and passed 30mins OCCT test - then i restarted to raise FSB and it wouldnt post! I thought I'd ruined the BIOS, and would have to RMA as the dual bios (on my P5Q Deluxe) wasn't working! Anyhow - I read in the manual that I could hold down "delete" upon turning the system on to restore the BIOS and it worked:) I was soooo happy - why did it do this at only 360?? I'm after a 475Mhz FSB for 4.25Ghz - which is realistic - Any of you know why It didnt post after rebooting on 360Mhz??

thanks

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

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

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

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 :up:

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. :up:

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.

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 :up:
Sergio

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

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.:D

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.

http://i431.photobucket.com/albums/q...tRD6-tRE-1.jpg

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?

I think now you should remove you AMD avatar :rofl:

impressive vid enjoy it and play :up:
