Retail Q9650 Overclocking Thread

[XmikeX]

lol thanks my friend just doing the best i can...now that gigabyte is not going to do a new bios for this amazing mobo

Hunh.. really? ..or maybe this will be like the x48 blackops adventure/experience, where they took about 2 yrs to dial-in a beta bios that fixed up most of the known bugs. (I'm actually impressed they went this far, considering how the quantum force group was gutted by foxconn - post-2008 economic-meltdown fears.)

I'm hoping for more from Gigabyte. Come on guys, I don't want to buy ASUS boards in the future.

andressergio has done great with his EP45-USB3 and his quads
you shouldnt have any problems doing 500fsb

Considering how much heat/watts my Q9650s seem to dump beyond 3.8 GHz, I'll be happy with solid ~4 GHz in a 24/7 air-cooled system.

+10 you heard that gigabyte !!!

I had a -WTF- moment yesterday with that motherboard. As I was building up OS, the system dropped off the face of the planet into some sort of limbo/endless reboot situation. I spent about 5 minutes cursing (as in "GIGABUTT!!!, I'M TOO OLD FOR THIS NONSENSE!" and 10s more words ) before I regained my composure. After stripping all non-essential components, rechecking connections/cabling, looking for debris, (clearing CMOS alone did nothing), etc, the motherboard once again came to life. It sprung back with a warning about a POST error and suggested I choose "last known good" from its menu.. OK...

All is well, for now..........

EDIT : For the record, the above happened at stock speeds (NO OC) with a (test-bed) Celeron E1200 @ F2d rom.

when giga dont like mem, skews or references will do this, consider this was reduced and a lot on the USB3P...i never use AUTO...if you gonna use do with NORMAL

Due to previous experiences elsewhere, I also avoid AUTO whenever I can. However, after this little event, I became slightly paranoid and set as many things as I could to AUTO... Everything seems OK right now, but I suppose I'll have to make some changes.

It's a shame this USB3P has no integrated boot-code hexadecimal led display.
I hope I don't have to invest in something like this : http://www.akl-it.com/en/our-product...179-post-probe

You have a moster chip, congrats

i really dont see the help of that mate, UD3 series are well known for the reboot loops...just they made better on this ones

[grishenko45]

just run 20 loops linx @ 4.230Ghz but with ram @ 1128Mhz - altered GTL refs to 0.670 and passed! but with highest cpu temp of 70c - is this OK? nothing else i do appart from linx will give temps of anything close to this = P95 is normally 15c lower than linx and games gives me high 40s

[grishenko45]

dropped gtl refs to 0.660x and dropped vtt to 1.28v getting solid 56Gflops will post screeny soon 81c cpu under linx load - i suppose thats ok as nothing comes close to this amount of stress, not game, not P95 etc.. it was only for 20 mins!!

EDIT: for some reason lowering those gtl refs from 0.670 to 0.660x has increased my gflops output - but increased my temps?? why is that anyone????

[grishenko45]

been messing with OC and i get this odd thing happeneing:
My load temps using 1.3375v were 82c (20 loops LinX)
But when I drop my vCore to 1.33125v my load temps are 72c ( 20 loops LinX)

why the massive drop in temps with only a 0.00625v decrease in vCore?

Cure time on TIM, ambiants, misreading sensors???????

I got this chip for nearly a few months now and I kept it at 4GHz with no problems. I saw everyone is hitting much higher so I tried to hit 480x9=4.32. No matter how I mess with the voltages, I always fail Linx. The included SS is set at 480 FSB and multi at 8.5 so I can be sure the mobo is not the limiting factor for 480 FSB. Any ideas?

Batch # L0826B006
Vtt 1.4
Vcore 1.35 BIOS LLC ON
vmch 1.26
Vpll 1.59
Vmem 1.96, loosened timings (stable as seen in SS. Will tune later.)

Tried Vtt 1.44
Vcore 1.425
vmch 1.34
No go...

Untitled.jpg

EDIT:

Tried 1.5 vtt
1.45 vcore
1.4 vmch

Still no go. Looks like I hit the limit with this chip? The highest I can get stable regardless of voltages is 4.18. I thought the B were monsters...

@pogiman:
List all of your bios settings using this template:

[NoGuru]

Yeah what are your skews and ref's at pogiman? They will make or break your OC.

[pogiman]

Here are my settings. I tried with one stick and four sticks of RAM, still freezes. Just the fact that its pretty stable by just lowering the multi makes it seems that the CPU just cannot go over 4.2ghz

@NoGuru - my ref are set to 66%. I tried 65% and system freezes as well. I havent tried higher yet.

Nope. I increased vcore to 1.475 and then vtt to 1.36, still no go. I then increased vmch to 1.40 still no go. For this test, I set my mem to 2.1V to be sure they are not the problem. It is the Gskill with powerchips, so imm sure they are not the issue. I am out of ideas for this chip.

On a side note: When increasing vtt and vcore to the above values, it freezes within 1 minute of Linx. Using the values Hoss311 gave allows Linx to run for 5 minutes before locking up. I am now testing it at 4.25vcore and 1.3vtt and so far, it has pass the first run. Could be the cpu getting too hot?

EDIT: Passing 4 runs utilizing 6900MB. 23 minutes without error. I'll do some gaming on it and see if its stable.

[NoGuru]

So if Hoss's settings are getting you closer, what has changed from your old MIT? Try changing those values one at a time in each direction until you can go longer.

[pogiman]

Ok Hoss's setting get me through at least 4 passes on linx but I crash in L4D2 within 3 minutes of entering a game. I also had the vcore lowered to 4.25, so it may seem vcore is not holding me back. Could be the vtt since it was at 1.3, however, in my previous tests, I had vtt at 1.5V and it still froze. GTL is always set at 66%. I will give it another go with the new skew settings at the higher voltages.

Some of the files were giving me a CRC error on all the drives. (cannot extract with winrar) It happens on usb drives as well. I am reinstalling windows now. Maybe all the lockups corrupted something? Oh well, more wear and tear on my SSD give me a reason to buy that 600GB SSD in a few years.

if it crashes on games after linx its MCH, pump it up to 1,42 and retry---VTT won't help and remember to keep it near vcore

Question: If keep all timing and FSB settings the same and I only adjusted the voltage settings, the GFLOPS change. I thought it was the mobo setting its own internal timings so I did tested it by retstarting and doing a "cold boot." I get the same number again. It is only when i change the voltages, the numbers change. Is this because the mch has its own timings that is adjusted automatically? The residual number remains the same, however.

How are the later B and C revisions overclock wise?

Anyone with a sub 1.4V 4.5Ghz 24/7 air stable chip?

4.5Ghz 24/7 air = not possible
