It seems like alot of chips go right up to the 3.4 mark like you said and start to hit the voltage wall and it takes a hell of a lot of voltage to get past that mark, or at least that is how it is been in my case.

Just got it Today, waiting for my better memory sticks.
what cooling r u using and what temps?? supercoolin btw thats a nice chip:up:

My rock stable clock in Windows 7:p:
CPU - 3.9ghz - 1.5v set - 1.52 actual
NB - 2.6ghz - 1.4v set to make sure its not a problem
HT Link - 1.82ghz
I'll get an update of the list tomorrow morning. I'm going to go a little higher now.
his cooling is in his sig.
Oh and I don't know if this is just my settings or what, but I got a 3.62x speedup in cinebench with 3.975 cpu and 2.65 nb with windows 7 x86. That almost puts it back to the speedup in x86 with the original phenoms. Using the beta driver it also adds about 1600 points to my open gl score in cinebench. I haven't tried to do comparisons yet, still just clocking away.
I was wondering if by any chance people can tell where they got their procs from. I want to know whos getting the best so far.
THX but it says "ERROR

Guess i wasn't fast enough:shrug:
Ok guys, from now on I'm going to ignore posts that don't show the two cpu-z screens. Its annoying to not have information when I'm putting it in the table. At the very least you could take two seconds to at least just type it in underneath the screenshot. Also, there's no point in posting shots of prime that haven't gone for 2 hours, they won't get added to the stable list. It would also be nice if I had a few more steppings in the table, you guys should go take a look at the holes in it.
Thank you to those that followed the format.
And could someone running windows 7 show me if they get the same fluke or if I'm alone in getting the 3.62x speedup.
Never ran cinebench b4, i hope this is what you wanted.

Windows 7 64bit
Ran it in 64 bit mode in w7 got 3.75 for speed up.
Also, ran it in 64 bit in vista 64 sp2 and got a speed up of 3.61 all same overclock.
Guys, been a while since I attempted to OC Phenom's so a prolly stupid question but better be sure.
My BIOS seems to set VID-NB to 1E, but everywhere I look this doesnt seem to be anywhere near 1.3V that used to be on Agena. Did those values change since Deneb, so 1E is the new 1.3V? Or is the VID-NB from Deneb a lot lower now? I dont want to screw everything up right from the start since I had a hell of a night yesterday installing all heat sinks:(
Also in BIOS my 'chipset' (whether this is northbridge, southbridge or what, I dont know) is in the high 40's, so I dont know what this cooling has done for me thus far but well:rolleyes:
So Windows 7 is even better at using multiple cores. I also noticed a big difference in time with wPrime on 1024k mode, about 10 seconds difference between vista and 7, and then another 5 seconds for the increase I had in clock speed. Right now the cpu is at 4.08 and nb at 2.8. 270htt is too much for my chip so I switched over to the 16x and 11x multis to go higher.
Edit: 1E should be 1.35v because thats stock voltage.

I used that table for my cpu-nb vid and mine defaulted to 1E. Right now i have it set at 0F and I confirm if its right by looking at AOD.
Oh lol, contradicting posts for the win:p:
OldGuy, it would make sense that 1E should be 1.35V then, on the otherhand I know my 3 DFI boards last year and they all have this awesome preferance to default into weird speeds and Voltages (although always low), maybe some power saving stuff effects the BIOS now and then.
McRuff, so you say that the HEX values you set according to that list actually do match in AOD? Thanks for the list, I already found that along with others but since I didnt know how boards get along with Deneb I couldnt be sure if those tables were still accurate;) To be 100% sure, could you verify that indeed HEX values will result in those Voltages according to that list?
At this point Im testing purely the CPU. My first run was 3.4Ghz on stock Vcore but I got a BSOD, I assume it was because of a failed OC but this is my first time on Vista x64 so yeah, no clue. I added a bit of Vcore, Vnb to be sure and set my Vdimm to what it is supposed to run (on DDR1150 that is, but doing DDR800 for now).
So right now this are my settings;
3.4Ghz CPU, 1.8Ghz NB/HT, DDR800
Vcore + 0.025V (CPU-Z idle reads 1.36V), Vnb at 1C (or 1D, forgot:p:) and Vdimm at 2.16.
I just finished 5 runs of IntelburnTest x64 from AgentGOD, and it didnt crash and the results shown stability. My previous run where I got a BSOD was with all Voltages at default. I assume 5 runs would be more than enough to continue raising Mhz's, when I hope to get my final OC Ill do 10 runs to be sure:rolleyes:
Coretemp didnt get over 38C, so that looks pretty nice:cool: If the temp is right, no idea:rolleyes:
My further plan is not to push too hard, Im afraid to kill more MOSFETS:( I mainly hope after Ive done the CPU to achieve a stable HTT of 300Mhz max, at least 275Mhz so I can run my RAM 1:1 with that. Also I hope to get my NB around 2.4Ghz or maybe a tad higher. I dont want to touch the Voltages too much though.
it is alot lower now. no way hex values can change. i find it extremely hard to believe that it takes ~1.35v to do 1.8GHZ NB, and ~1.37 to do 2.0GHZ NB. the agena could do this without sweating at 1.3. on the DFI board, default is 1E (1.175) and it takes 1D to do 2.0GHZ NB (1.1875) @ 3.6'ish. the listed table should hold true (the one i posted here in another thread which was taken from polygon's thread at lejabeach) for all boards. whether the bios on that particular board adheres or +/- is another matter...
edit: stock CPU VID for the DFI board is ~1.31v for Phenom II.
new foxconn bios helped out stability a tad!

The next notch up with a stable prime.

Now I'm testing 4080 with 2.8ghz nb, hopefully it works well. I also did a 32m and it gives me third for the 940's over at hwbot.
NCspecV81 what are those clocks on air or water?
If air very nice probably the first to get that high.
