Retail Q9650 Overclocking Thread

[nkresho]

Just got three more runs in. 4005mhz, 4104mhz, and 4203mhz. All IBT stable.

Voltages are on the screen shots.

I'll be running prime eventually, I'm just too excited to stop and wait that long.

4005 @ 1.1625v bios / 1.136v cpuz


4104 @ 1.18750v bios / 1.168v cpuz


4203 @ 1.23125v bios / 1.2000v cpuz


Still working on 4302mhz

nkresho...so are sick results, very nice job.

VERY NICE mate

remember to blend cauz in my case i passed on low volts IBT and then blend fails instant thats at low speeds < 4300

maybe a notch or 2 but the chip seems awesome congrats !!!

[nkresho]

It's getting more dificult to keep the volts as low.

Here's 4302mhz @ 1.275v bios / 1.248v cpu-Z

VERY NICE mate

Thanks! I will start blending tonight. I'm going to start back at the beginning at 4005mhz and work my way up with the blends.

Very nice nkresho.

I updated yesterday to bew F10f bios...seems that they loose some timmings it left me do this at tigh memory timmings on lower volts, the same on bios F10b (tough it scores more latencie on mem) does not run not even minutes...

x8,5 and x8 + tight mem timmings and speed has been always a no go on my system...yes on 9 multi but this seems good...7+ hours blend all nite



Cheers
Sergio

Very nice run Sergio.

My 9550 4400mhz blend. Still running, will try and get stable.

Sergio, I wouldve thought you could get that at much lower vcore. Its so strange how you can have your CPU stable at one Vcore, but need to increase Vcore to get Blend stable...I wonder why that is, I am experiencing that too

its multi 8,5 mate and gskills are at 1229 pl8 on tight timmings...i can do at the same vcore 4400 on x9 multi...

gskills push hard the MCH

OK sergio, another oc for you to try my friend. Prime blend 14hours q9550 EP45-DQ6 board. I know this is not the q9550 thread but we have been testing this chip and board with Sergio's q9650/UD3P and my other q9650 using the 8.5 multi and same load vcore. No LLC on this board so idle vcore is higher.

[nkresho]

Wow, that's a really awesome 9550 there. Most people will never see that type of speed from a 9650.

I'm still working on my first blend at 4005mhz. It's looking like I'm going to get by with 1.136v. More to come.

[OC Nub]

Thanks nkresho.

WOW!!!! That is probably the best 4.0ghz vcore I have seen on any q9650. Congrats on that chip.

[nkresho]

Thanks nkresho.

I feel like I deserve a good chip after dealing with my last one. I spent hours just trying to get 4.3 stable on it, and that was at nearly 1.4v cpu.

I'm sure you can understand, having gone through more than one to find a nice clocker.

OHHHHHHHHHHHHHH damn very nice mate you deserve it

Hey guys

Im experimenting the world of 8,5multi on my quad and there certain issues that bios after bios repeat, for ex look at this one

4352 (512x8,5 ) 7h+ blend



I used for 1.20VTT .785cpu ref and .80mch (relation) ref BUT when i reboot PC turns off and on again and when i enter bios gives me the red Screen saying OC failed bla bla...

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 )

Yes I understand completely. Spent around 5 months trying with no success to reach 4.4ghz with 2 chips, thinking the whole time it was me that was the problem and not the CPU.
Again Congrats, will be looking forward to seeing your posts with this awesome chip.

damn Tom you really made it and are the 12+ primmer here

Very Nice mate Congrats

[OC Nub]

Thanks you Sergio.
Pushing harder now, running blend at 4450mhz.

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.

[Zucker2k]

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

[OC Nub]

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

[nkresho]

^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."

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.

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.

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
