I removed the X3 720be then installed the 955be today in hopes of running some 3D bench tests. Every test was under air-cooling using a Tuniq 120. I used my M3A79-T Deluxe DDR2 motherboard 803 bios, 2x1 GB OCZ 1200MHz memory sticks and both Windows XP 32-bit and Windows 7 Beta 1 32-bit. I did not do a fresh reinstall of the OS's, which may have caused some of the problems during testing but I'm just not sure yet.

I'm not sure what's up with my bios the M/B sets the processor volts too high the X3 720 was set at 1.44v and the 955 was set at 1.47v at first boot after each of their installations? Both CPU installations after a cmos jumper reset. Of course I reset the CPU volts lower before I continued. I ran out of time before I could do much testing just as well because I think I have a bad set on my HSF as the temps are much higher than I thought they should be. I'll reset it tomorrow. The tests under XP did show some promise with higher CPU scores in 3DMark06 compared to Windows 7 but I could only use one 3870x2 so when I started running out of time I just moved over to Windows 7 and ran a couple of 3D bench tests to post here and stopped for the day. BTY for some reason AOD 3.0 wouldn't start in Windows 7 but ran fine in XP so I reverted to version 216 which ran fine with the 955.

Sorry for the low clocks in these early tests but I think when I find the combination the 955 wants it may well complete the 3D benches @ or above 4GHz on air but for me today I didn't find it. During the CPU tests in 3DMark06 the CPU temp was in the low-mid 50sC @ 3.2 GHz and a little on the high side of 62C @3.9GHz under air cooling so like I said I think I need to reset the Tuniq tower 120.

Maybe these AM3 processors are going to prefer an AM3 M/B's I know my 940 clocked higher than my 720 on this M/B so maybe the 955 will turn out the same but it's way to early to say. I'll form an opinion after a lot more testing.

I'll try to in the next few days if I can get a good set on my Tuniq tower to keep the temps down a bit.

Thanks for all the replies. I hope to try a few more things today. Maybe the 955 will have it's running shoes on today.

I reset the CPU heat sink today. It didn't look as if I used enough thermal compound the CPU hasn't been lapped so it isn't flat. Anyway that was the problem as the CPU load temp after the 3d06 CPU tests is around 56C (before it was 62C+) which is still higher than I want but I don't plan to lap this CPU just yet.

I ran a few more 3D06 tests and was able to get a little more processor speed but I needed a bit more NB VID to complete the test @3958MHz. I think at this point the two 3870x2's may be the problem with me testing at or above 4GHz on air so I think I'll remove them and try one Evga GTX 260 just to see if that eases the systems loading and heat I'm getting now.

This 955 doesn't like a lot of volts the 1.52v is about it on air if I set it higher 1.53-4v the test will not complete. The key To 4GHz testing may be keeping the CPU temp closer to 50C?

I'm not sure that temps are the issue TBH... I have a feeling it may be more down to electro-migration

When I tried at 4.0Ghz and 1.55v, my load temps were still under 50C for moderate load like 3DMark testing.... but it wouldn't complete the test, so I think that possibly the high voltage may be the issue, and suspect electro-migration being a possible cause..... of course not a lot we can do about that.... it just is what it is, and will vary from CPU to CPU...!!

I've considered trying to disable 1 or 2 cores and running the remaining Cores at 4.0Ghz to see how it affects the scoring as well.... havn't felt up to a long benching session to test it ot yet...but I may give it a go when I feel up to a long session at the computer...

What RAM are you using there Oldtimer.... your getting good clocks for the Vdimm your using...!!

Way close to 4GHz but no cigar. I tried changing the GFX cards out but it didn't help. I feel like Thomas Edison because now I know a thousand things that won't work. At least in my efforts to get this system to complete 3D06 @ or over 4GHz.

I ended up lowering the CPU volts one tick and raising the NB-VID one tick then ran a combination of 19.5X205 to get 3997.5MHz that allow the test to complete. I tried many, many settings @ 20x200 but none would run 3D06 to the end of the test.

Very nice result though.... and at 3997.5..... I think you can call it 4.0Ghz... I think its safe to say that the extra 2.5 Mhz really wouldn't make that much difference...

How is long term stability for that 3997 @ 1.51v, what are temps like on air at those settings..... would it be a practical 24/7 OC I guess is what I'm asking.... if it is then it makes the 955 a very attractive upgrade option...for folks who are currently using B3 stepping Phenoms on AM2+ mobos, and looking for a gradual upgrade to AM3, starting off with the 955 would be an excellenet upgrade IMO... offering good clocks with the upgradeability to AM3 platform....

I would have been happier to see 4Ghz+ though given the added 200Mhz stock clocks over the 940BE, but if 3.9 Ghz is the normal 24/7 stable OC at reasonable voltage on air then that would be about right based on 940BE.... generally 3.7Ghz seems to be the norm for the 940BE so thats a 700Mhz OC, so going from 3.2Ghz to 3.9Ghz with the 955 would be about right really, just gaining the extra 200Mhz....

It'll be interesting to see how things develop and what the standard OC seems to be for the 955 on air and water.

Very nice scores though to be honest I would have expected a slightly higher CPU score, going off my 5400 CPU score in 3DM06 at 3.83Ghz.... with almost 167Mhz higher CPU Clocks I would have thought that 6K would have been possible for the CPU score, or is that being unrealistic...???

I was sure 4.0 would be a 24/7 overclock, at least. However, we will be changing over eventually to AM3 and DDR3 so you are right Kaz this is definitely the best first step. Its tough for you 940 owners however, since these have come out so quickly relative to the release of those black beauties. Im definitely in on one of these, and will have one in the coming months.

Thanks for the clock by clock log Oldtimer, this is definitely great information. I bet youll get a stable 4.2 before you are all said and done.

Thanks Zodgrod009, it's been interesting because the 955 reacts to settings differently than the other Phenoms I own but then again they all react differently in one way or another.
You were talking about 4GHz 24/7 using the 955, well IMHO that may become common using water-cooling. Air-cooling @ this o/clock (based on the hardware used in my tests) will become more difficult. If I planned to o/clock the hardware I tested 24/7 I would set lower volts (=lower system temps) and shoot for 3900MHz 24/7. Like I said this is just my opinion based on limited testing using an AM2+ MB and related hardware.

The DDR3 MB's may o/clock to 4GHz @ lower volts thus running cooler and making 4GHz on air a little more common but I don't have a AM3 MB to test (yet).

Unclefester1, I don't know that I can run any faster but I think this 955-processor can.

Kaz, I noticed that my 940 liked to be cool when testing and the 955 is similar in that regard when the temps during testing were higher than 55C it became less likely that the test would complete, maybe electro-migration is another determining factor. I honestly don't know.

I've tried 3D testing using less than four cores but the 3D06 score was always lower based on the number of cores used during the test. Maybe you can find a way to fool the testing software?
The RAM used in the testing is the OCZ 1200MHz bios set @1067 5-5-5-15. If I set the Vdimm above 1.98v it sometimes will not complete the testing. That's just the way it has always reacted no matter the processor or MB in which it's installed. It runs ok on 1.96 also.
I'll install a demanding game and test the systems stability @ this o/clock very soon.

I don't know what's up with the cpu score. I guess I would need to look up some of my old 940 3d06 tests to compare with the 955 being that they both were using the same hardware.

As to comparing 940 to 955 o/clocks yeah I would think that yardstick of 940 3.0GHz to 3.7GHz and 955 3.2GHz to 3.9GHz is about right but it's still very early. Once the bugs are worked out of the AM3 MB's the 955's may clock a little better though.

dimwit13 the AM3 MB's should make a difference once they get the bugs worked out. They may even help now for all I know.

I won't do it for less than 20%, I just won't and that's my last offer! Unless you won't give it to me of course then I'll take the 10%. Lol!
