it reached 500 FSB but not with a multi 8 or 8.5 it just doesnt work :/ and if the other chip doesnt work i will stop at 4GHz cause im just 15 so i dont have the money for a new mobo, so ican reach 500MHz clock higher..

The GTL Refs are set to 0.670x (0/2) and 0.690x (1/3), and NB GTL Ref is on auto at the moment.
I can't call it stable, as I have only run large FFT's at those settings for around 40 mins. I have not been able to spend much time on testing.
I did run HCI memtest to load the ram and NB and I did get an error but it may be the ram, as I'm using the sticks I benched on DICE at 3.00v+
I'll use some known good sticks and do more testing but I think it may take 1.44 - 1.46vNB for stability.
Perfect GTL's differ from cpu to cpu, and also depend on Vtt. Setting them to above settings improved stability for my chip.
So I just upgraded from my sweet 1.2125VID E8600 to a used Q9650 I got from a forum. Turns out the Q9650 is 1.225VID!
First, I'd like to say that... WHOA... Quads need so much more voltage for stability..........:shocked:

On the same board, my E8600 Did:

Anyway, I was stuck below 2000FSB because anandtech suggested no more than 1.36vTT...
I stumbled upon this thread, set my vTT to 1.4v and 2000FSB is mine.
I haven't downtuned my cpu voltage yet, but that's up next after linx verification.
All my stuff is watercooled:

I think your overvolting your CPU @ 1.392v. You should use a lot less to get stable at 4ghz. Heck I thought mine was high for 4ghz and we both have the same VID. It something else that is not stable.
My latest bench, took me a week to get there WITHOUT Acards ANS9010:
PCMark05 23.7K
Now I only need 689 point to consolidate the Q9650 ranking :up:
Very nice Jor3lBR, good work.
Great work as usual Jor3lBR. Congrats :up:
First of all Jor3lBR nice work realy nice oc :)
Does annyone know's what max safe voltage is for P45 Chip?? cauze if i google i find lots of stuff but all diffrent vallue's. some people say you need more NB voltage aswell when you use X-Fire or extra ram so what's the max safe voltage for p45 chip :P? and what is the max safe vtt :P?
Thanks guys! It took me a long time!
Regarding max safe voltages that is a subject directly linked to core temperature. If you plan to keep it under 60oC it will last you a lifetime with 1.7vcore. It's very relative.
Thanks teammate (XS HWbot), you will definitely improve your scores as PCMark05 is very dependent on HDD scores like Xp Start Up, HDD General Use and Anti Virus Scan.
I used this formula to improve my scores > HDDERASE each SSD > Create Raid_0 array > Diskpart Align=128 > Vista32 n lighted > the rest only on our team thread :up:
Finally back together guys...

Heatkiller backplate facing the right way this time... LOL
Always good to maintain the positive attitude!
I fried 2 UD3P's and almost killed my golden quad with insulation issues.
Now back to your benches :up:
Oh yeah, good eye.
I put a 45 on the bottom of the gpu before filling the loop because of that. Thanks for spotting it though.
Well my P5Q-D wasn't showing me a lot of love, so I dusted off my Maximus II Formula. I'm currently focusing on Large FFT's as its where this board has the most trouble, small FFT's and LinX are easy by comparison.
The vcore and probably Vtt are obviously much higher than I need for the clock, I'm just testing the FSB only. I haven't had much time with it, but this is what I've managed so far.
1 HOUR+ Large FFT / 467 FSB / 1.26 Vtt / PL 8 @ 1.30 vNB / 560 MHz @ 5-5-5-15

So, I got the new board installed and all my clocks from 4200mhz up to 4500 are unstable in prime now. The bios is the same (f9) as are all the settings and hardware (except I am now watercooling the nb).
I thought the second pump might be stretching the limits of my power supply (hx620), but the voltage is sitting stable if I check for droop with my multimeter on the 12v and 5v lines. No change from idle to load, and well within specs.
The board is the same revision as well (1.1) so I am at a loss. I have another board coming back from rma some day, so I will have to test it on that one then.
Any ideas what might be different between the two boards?
Might my gtl values be off?
I noticed a bit more vdrop with the new board today and yesterday as compared to the last one. I'll post them later when I get home, I made a chart for all bios voltages I usedand the corresponding cpuZ voltages I was seeing. This new board is one step lower, as in, I need one bump higher to get one higher value in windows.
I really want to get you guys some screenies of 4600 and beyone, but I have to start from 4200 again.
I hope I didn't hurt my chip with that backplate stunt I pulled, but I have a good feeling it's just that this board just isn't as good as the last one.
^^ Since you're now watercooling your nb, have you considered lowering the voltage a notch or two? I'd play with the vtt too a little. Have you hooked up extra stuff to the power-supply since the switch?
Yeah I really hope nothing damaged your chip, but some of the lines in the back of the mobo might just do that when they are shorten. Very rare to happen but it can.
I always use a multimeter to test if the cpu plate is not grounded accidentally (touching any pins), before I power it on for the first time.
Try what Zucker suggested first and work on your GTL's again, they change from mobo to mobo.
well heres me at 4.7...I basically just threw up the voltages to get there, no real tweaking, I think Im running a PL of 13. My MCH was at 1.6 and I was getting freezes during my Vantage run. I touched my NB and it was burning hot, I think that was causing the freezes. Ill have to find a way to rig a fan to blow on it. The CPU test in Vantage runs fine though, so I think CPU Vcore is adequate.

Wow, 4.7GHz, 523fsb and <10 1M Pi! Lots of volts :) Did you just get hold of your quad? Where from?
