Hardware changed, but Zippy 850W and TTBT still follow
here is some preliminary clocking
i had a buddy's 920 in my rig earlier(his board is out for rma), but my 940 came today via snail mail unexpectedly. got a quick clock out of it that it can probably run with lower volts:
http://img133.imageshack.us/img133/1...8088of4.th.jpg
the nb's on these new phenoms impress me. the 920 was good for 2.5, now 2.6 on this 940. i could boot at 2.8, but it would fail prime instantly with pretty much any voltage. 8gigs of 1066 with the NB at 2.6 required 1.325v
now, im going to push the CPU core higher. 1.55 is the limit of safety, correct? im afraid to push really high on volts because i've already blown up one of these mobos (dfi 790fxb-m2rsh, strangely everything was at stock settings). i do have another one as a backup, though.
And that impressive NB clock is default or had been overclocked? :)Quote:

Major update is about to be uploaded. Thanks a bunch for the program Particle, I'll get to moving everything over during next week. I have to finish packing and drive back to college tomorrow so no updates on the list from now till monday. Now I just need to figure out how to transport the computer since the front two screw holes to connect the vapo case to the other case were in the wrong place so it just hangs if I pick it up from the top. I also need to finish doing the wiring.
You mean that high voltage can affect not only on the cpu but on the mobo?Quote:

http://i30.photobucket.com/albums/c3...11_OCvalid.png
Same thing is with my 9850, around 1.616V is the max voltage the processor is stable. I know about this limitation, but I didn't knew the mobo can also break down.Quote:

If anyone is interested I've did quick NB/volt scaling test.
- 1.175V good up to 2.35GHz
- 1.225V good up to 2.5GHz
- 1.25V good up to 2.65GHz
- 1.275V good up to 2.7GHz
- 1.335V good up to 2.8GHz
- 1.4V good up to 2.94GHz for now ....

All tests done using 11x multi for NB because 12x multi is no boot for me. I wonder when Gigabyte will add positive voltage adjustement for NB in their BIOS. It's retarded to have 20x NB multi and no option to increase NBvCore :shakes:
update for my new speed.
placed 3 130cfm blowers on the pa120.3.
all voltages at stock.
cpu 3616mhz with nb 2210mhz.
aod shows wrong values.
didnt thrust the temp, saw it go up, so i opened the window :D.
in holland its around 0 degree at the moment.
@BertM: If you want to fix AOD readings just load BIOS Defaults or clear cmos. :)
BTW very nice clocks indeed!
k i will do that today probably.
few minutes ago i saw that i ran it with cl 5 7 7 24. bah :mad:.
htt oc with cpu to 3654 or just multi up to 3700mhz is a crash in short amount of time.
you wouldnt expect that while 3600 is stable probably 6 degree higher.
there is a hard barrier at around 3650 i asume.
im now testing 3636. (edit: it crashed at 15 minutes to go)
Quick update done. Changed the name of the thread to a more recognizable one.
the NB is overclocked.Quote:

There's a stable setting. Updated list is about to get uploaded. I'm down at school now so I'm just going to waste all my time on updating this thread and making mine run faster:D.
3.675 cpu with 1.425v and phase cooling obviously
2.45 nb
980mhz ram @ 2.1v
1960 ht link
Windows Vista x86
I can't seem to get mine to even take a SS at 4GHz. Damn you, Thermal Monster! I can tell this chip is all about the temps. Adding voltage markedly increases stability until temps get too high--then it crashes. It's kind of like how the older chips used to behave years and years ago before we hit that period where voltage only mattered to a small extent.
First test run (barebones) mine did okay with AMD HSF - results so far:
Stock vcore = 16x200 = 3200
Added 0.1v = 17.5x200 = 3500
Well I have a dead stick of RAM (Corsair Dominator PC2-1066) so RMA today - have to wait for replacement........

I'll be installing Windows 7 on it later today, right now its priming at 15x255=3825 @ 1.475v set, 2550 on the nb, and 1785 ht link. Don't have time to install it now since I have class in 15 minutes:(. But I will be getting 4+ghz stable by the end of this week no matter what, otherwise this phase unit is absolutely worthless.
Edit: I would recommend setting your own timings as sometimes it screws them up royally. I always go to the 800mhz divider and do 5-5-5-15-26 at 2t, and if anyone knows how to do a higher trc on my board in the bios it would be much appreciated.
so old guy you really want this darn stepping ?
280 is here :D
I hope to install this afternoon as well. Let us know if you hit any snags with anything so we can learn from your problems :DQuote:

I'm going to start the install in about 20 minutes, need to wait for my 2 hours of prime to finish. I really wish my network plug hadn't died at the wall, cause now I actually need a wireless card until I get it fixed.
By the way, has anyone noticed a newer version of aod than 2.1.5 yet?

Anyone been able to get high hypertransport like 2400+?
I've heard it increases gaming performance.

I like it, I had an ASUS M2N32-SLI Deluxe with a 6400 X2 before and I'm just getting used to the DFI BIOS, I've just updated from the Bios that was shipped with it so I will now be able to adjust the HT link which was locked on the original.Quote:

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.
Nice. Stepping/batch?Quote:

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.
http://i380.photobucket.com/albums/o...hw732bit-1.png
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.

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...Quote:

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.
