The Phenom II List of Overclocks

[kazgirl]

Thats odd I though you'd at least hit sub 10s with that clock speed.
I got 10.480 with my 9950 @ 3570Mhz.
Kinda disappointing .

I think I'm right in saying though that, HondaGuy is using an SB600 M3A32-MVP mobo, so no SB750 benefits, and I think from most of the ss's that he runs with CPU Tweak disabled, which will also drop performance.

With CPU Tweak enabled however its possible that he wouldn't be able to get as high core clocks though, so its a swings and roundabouts thing, lower clocks increased core performance or higher clocks and lower core performance....

Might be a bit of a balancing act as to which one is better...????

Quick tests:







Not even tweaked yet. NB is pretty low now. Watercooled.
Tweaking more when i get back home.

not exactly. there are no applications that currently run 100% cpu usage on every part of the cpu for at least 8 hours straight. most people can have computers that aren't even 1 hour prime stable and they have no problem with it at all. stable to me is if you can run every single application you use without ever having an error. not putting so much power through your mosfets that they might explode when in any other real situation it wouldn't happen.

Stability means that the system will not error even under extreme load. While you may never see the use that the stress tools put on the system, it is possible to get such high load (as the stress tools prove).

It says more about the *huge* amounts of current (Amps x V) that the poor vrms/Mosfets must take without melting/damaging the PCB/traces.

We do not want to burn our boards/test "board-clocks" do we?

Firstly "current" is not amps times voltage, I believe Amps x V is Power. Current is Amps.

But more importantly, if the board cannot hold the amount of stress you are putting on it, then you need to back down on the stress being put on it (by lowring the OC), simple as that.

I got my cpu this morning and started with some simple tweaking, I'll use these settings as my base for finetuning. Idle temps were around 30 degrees Celcius and the highest load temp I've seen was 52 degrees, ambient temp is 22 Degrees.

Okay, here we go:

CPU Model: Phenom II 940 BE
CPU Full Stepping: CACVC AC 0850CPAW
CPU Frequency: 3800(19x200)
CPU Vcore: 1.55
NB Frequency: 2200
HT Link Frequency: 1800
ACC Enabled(don't know if it does any good yet, I had to flash the bios to 1.5B1 for the motherboard to post with it enabled )
Memory Frequency: 1066MHz
Memory Configuration: 2x2GB 5-5-5-15 1.9 volts
Memory Unganged
Mainbord Model: MSI DKA790GX Platinum Bios 1.5 Beta 1
Cooling type: Custom water
Windows Version: Vista Ultimate x64

Old guy,

Your results don't surprise me and I don't think your chip is a dud. I've yet to see uber clocks on that asus board "brickhouse" PWM or not.

I have seen the board take a dump when trying to acchieve uber clocks however.

Not saying that the board is junk yet but the trend I have seen is leaning that direction atm.

That cap next to the socket isn't helping people looking for subzero usage out at all either......

Whats your last 5 digits by the way bottom row without me scanning through the thread?

[Oldguy932]

I'll have to check that when I put grease in the socket, I've never paid attention to more than just the stepping so I don't write it down or anything. It finally seems stable with 1.525v set for 4ghz. I bet my gx board would be better except that it maxes out at 1.25vid. With the 1.5v I can set with this board I would have had a good chance at the WR for the regular 9600.

Do you know an easy way to tell when you've reached the limit of phase cooling before you hit positive temps with the cpu? The evap head is sitting at about -38.5C, the bios reads at 7C, and the cpu still reads at 0C.

Did you happen to write down your stepping before you put it in?

Yeah, I'm not ordering my 940 from the egg, the microcenter that's 2 minutes away should have them in stock so I'm just going there even though its slightly overpriced.

Edit: Just looked again, found it for 275. Definitely going to try and pricematch it at microcenter so get like $50 off what their selling price is.

i just made a occt 1 hour run at 3.3 and the rest all stock.
what more data do you need?.
gonna write down the batch nr. in a moment.

@OldGUY............You have to make this clear to all that the "Minimum Requirement" will be ....1hr OCCT "CPU TEST" @ High Priority........ Not Mix!!!!

[Oldguy932]

I'm fine with 2 hours of prime or 1 hour occt. I'm going to go change it after this post.

Thanks for the new information guys, can't put it in yet though because I'm on the Q9450 and not my 3.5 year old lappy with the classic Pentium M(That still manages to run vista x86 very easily after startup.).

I just got my 940 from microcenter, took like half an hour to get the price match from 334 down to 275. Its just annoying because 2 different guys had to look at the price on newegg, each at different ends of the store. Also had my girlfriends dad help me with the case, had to get stuff cut and drilled for my vapo, and with my luck the case sits about 3º off center. Now I get to wait till this evening to actually build the computer with her.

Keep the results coming guys.

Edit: Just updated the list.

Reviews were needing 1.5+ supposedly for 3.5-3.7 yet GondaGuy can do it on stock

Either they just suck or he got an amazing chip.
