Nice Sergio. Your vcore looks about right for your 1.25VID chip (I have a 1.25 also). I need about 1.38 for 4.2Ghz and around 1.4-1.41 for 4.4Ghz so I'd say your on the right track.

I think these chips can withstand <1.45 24/7 just need to keep an eye on their running/load temps. But definetly H20 on CPU if using 1.4v+ 24/7

Thanks mate :up:

All my tests are on 26C to 27C ambient in my room and outside more than 30C, I'm on water sharing the loop with an ultra vmoded, but i got great temps, the 3 san aces at the rad are awesome. Also i have a fan blowing air on the NB and the Gskills.

Can you tell me your settings for 4200 on vcore set, pll, vtt ? so i try :D I've been waiting for this for more than a month as i had horrible unstabilty issues till with all the help from ppl here i found it, i just needed a good combo of a rock solid setting to start with.

Cheers

No problems mate:

My settings for 4.2Ghz on the key volts you mentioned are below:

1) vCore - 1.382 (real via CPUZ)
2) CPU PLL - 1.61 (real via Everest)
3) CPU VTT - 1.38 with 70mV GTL references for cores 2 & 4 in BIOS

Hope that helps.

All in all you are on par with your current volt settings. The above volts were set quite a while ago (around Nov 08) so I was a little new to the Q9650 back then.

I think you can lower CPU PLL and VTT a little more as I passed 1 hr prime blend using 1.34vtt with 4.4ghz...overall the above are relatively safe and I don't have a problem using them 24/7 :up:

Sure your chip is vid 1,25 on coretemp ? seems like better than mine...

Will try those settings, do you find PLL helping ? i tested with really poor effect, wich in my case is vcore and then vtt

Thank you very much :up:

Temps where high but I think I can squeeze 4500Mhz on air (500x9) just need a little better Air Cooler.
Hope this helps Q9650 users! :up:

Hi Guys, Just found this thread :)

I'll be getting the UD3P later this week and hopefully It'll do far better with my Q9650 than the Maximus Formula did, as it's hitting a wall @ 3.8Ghz :(

These posts will help me enormously so thank you, and thanks especially to Jor3lBR because the above test & infomation will really save some time :up:

I'm pushing upwards and have a small question that I would like resolving... Basically, prime95 is failing on core 2 (ie. the third window... core 0, core 1, core 2, core 3) and I want to know which gtl ref is associated with this core. I don't get bluescreens or freezing, just this core fails during small fft, and usually within 2-3 minutes. Should I be touching gtl ref 0/2 or 1/3? I've read opposing things on which core is on which die and is associated with the relevant gtl ref. So, if someone could clarify it for me I'd really, really appreciate it.

Thanks a lot.

You made a great decision. I had a Maximus Formula as well and the UD3P will bring that 9650 to life! You picked a great template to use as well.

@ Jor3lBR, what bios are u using?

Sorry Nugzo I forgot to say that on my posts, I've been using F7C since my AIR results.

I tested and my chip needs more vcore to achieve 4230(470x9) stable, or maybe more VTT i don't know...

This is what i am testing now

4203 (467x9) MEMS 1245 PL7 Stronger

I heard about Intel 45nm OC degradation, that after a few weeks or months it become less & less oc able.

Is the Q9650 also affected ??

No, actually all CPU chips do. It's a temperature thing. If you let it run hot, it'll degrade a bit over time. Usually a small vcore bump'll fix it.

Looks like your IBT runs are good for 4.2Ghz.

Have you run Prime95 small FFT for 470x9? I'm pretty sure you'll get core failure if using those 4.2Ghz settings but just run it and tweak from there.

Normally my order of tweak in small fft is the lowest CPU-related volt then lastly the vCore - it really depends what your individual chip needs

Another thing you may want to try is:

CPU vCore - 1.42
CPU PLL - 1.61
CPU VTT - 1.42
GTL refs - core 0 - auto, core 1 - +70mV, core 2 - auto, core 3 - +70mV

Note: the above settings allowed me to small fft on 495x9... so they should be ample for you. I think 4.25-4.3 should need (at most) 1.4vCore and 1.4-1.42 CPU VTT

*with the GTL refs you may want to use the formula VTT x GTL ref then try different GTL combos that yield the same result eg .67 GTL that yields the same value as your current setup then try +/- 1 or 2 notches. Although from my experience I did not have much luck with this but I didn't try it for very long. Also i'm assuming you have been keeping a log? If not it would be a good idea

Nugzo - Are the GByte boards as well made as the Max Formula?

Just another couple of questions for you guys who have the UD3P highly OC'ed....

1. How are NB temps over 4.2Ghz?

2. Is there a jumper for a BIOS reset?

3. What BIOS should I use? (already DL F5) in anticipation :)

When buying a Q9650 now, what do you think is the best chipset/board for the best OC? X48 or P45?
01-20-2009, 12:32 PM
xguntherc

P45 I've been told by more than a few people.. get a P45.

Also at those prices i really really want to sell my Q6700 that is my backup and get a Q9650 for a backup.. :)

oh and I got bad news, Not sure if it's just a Bios problem and a new BIOS would help me. but on my ghetto 750i FTW Motherboard. the CPU VTT only goes to 1.4 maybe 1.45 I can't remember. but thats as High as it will let me take the vtt/fsb votage. So either I need another BIOS revision. Or the eVGA 750i just doesn't go that high, but then again it's not really known for it's multiple options in the bios, as there isn't very many.. lol.

(This is where I say your right, my 750i sucks).. lol jk jk. it sucks but it's done me well. I was able to hit 4.3 Ghz a few days ago. I couldn't bench with it, kept crashing. but I didn't go over 1.368 v either. I guess I should try raising voltage even higher. as these are only bench runs, I'm not going to leave my voltage that high.. ever.

Is PLL really helping you ? in my case i really don't see it effects...

Quality of the ud3 is close to the maximus. real close.

Dont know about NB Temps... This board doesnt have a NB sensor.

There are 2 pins for the clr cmos instead of 3 like a lot of boards. I have a power button from an old compaq hooked to it. Honestly i've never needed it. If your OC is bad, the board will revert back on its own every time. It'll power cycle a few times.... just let it do its thing and it'll boot at default settings.

i think F7c is the best bios.

You still have NB air cooled? and it's still ok at 4.5Ghz.

North bridge only needs a small fan there, this board runs cooler then any other I had, probably the extra cooper.

I did all my runs on stock sinks on SB, NB, and Mosfets:
-Q9540@5095Mhz;
-Q9650@5005Mhz;
-Q9650@4400Mz on AIR;

Check my sig for results.
