Could B3 Phenom be the rebirth of AMD....+1000MHZ OC done!

[Tony]

Hi!

I Have perhaps just found why I did not succeed in exceeding 2700MHz. My phenom runs in 3Ghz nowadays. But for only 3 cores on 4. The 4th (core #3) rest in 2700Mhz. If I augment it, my pc freezes.

hence we need bios to have individual core multi adjustment or the ability to run with just 3 cores

[KTE]

Definitely! Have you passed any such word on to MB MFGs Tony?

yea MSI said that isn't gonna happen

[charged3800z24]

The bios that came with my MSI had the ability clock individually but it was with ratio's and a pain.

[Calcifer]

the asus m3a can disable cores so ou only have 4, 3, 2 or even 1 core avtive in os but you cant choose which core gets disabled

Which one?
Are you sure it could clock each core separately?

[SyDe!]

I have the K9A2 Platinum MB with Bios 1.4 like charged3800z24 and I can't clock each core separately...

[Calcifer]

i wanna clock each core seperate so after i change the multi in aod to say 14 on core 0 how long should i stress it with Prime95 for?

[QuietIce]

Prime95 is a good stress test for temps and some stability but it's not the only thing you need to test with on these CPUs as some seem to run P95 fine and lock using IE. I'd say a couple of hours on P95, a couple of 4x SuperPi 32M runs, a couple of video benches, some mixed usage (surfing while running 1x P95 and 1x SuperPi) etc. And even then don't expect it to be 100% stable!

For a quick stability test while OC'ing I still like 4x Prime95 large FFT's as that's what seems to crash mine the fastest. Once each app gets to step 3 I move the clock up again. By then the cores have reached maximum temps ...

Is a good CPU checker & tells you what part of the cpu failed.
ignore the failed to load driver in Vista64 if you cant be bothered to do the F8 trick as it will still run anyway.

[AlabamaCajun]

Ask them to give us Access to the RAM divider and NB Multi (It's locked on my DFI).

Also on RAM, tony may be cable to light this one up. Typically DDR2-800 uses TRC=24 and DDR2-1000=45. The problem is, BIOS Maxes out at 26 on the DDR2-800 setting. If I bump the ram to 900 I can't set it about 34 which would be needed.

[QuietIce]

Would definitely like to see better work on the RAM dividers, too! The ASUS has 533, 667, 800, and 1066 but 1066 won't work without 1066 RAM. It shows up as an option but boots at 800.

M3A32 has the NB multiplier up to 11X listed (and checked). 12X and more will show up in BIOS using the "+" key but I haven't checked for sure by booting 12X - I'll give it a try. I assumed all boards would do NB multi so it wasn't an issue until now ...

[charged3800z24]

I can set my K9A2 to 1066 on my 800 ram but the system doesn't stay stable. But it does boot up and show 1066. The first release of MSI's bios and the ability to change cores individually.. I had a forum that a guy explain the way to do it.. but it was sorta complicated.. now it just has multipliers. It was done with ratio's.. i'll see if I can find that.. but it would not recognize the 9850 correctly...

Prime95 is one of the best stability test, if you are looking for thermals, the OCCT tool is really good at stressing to the same power levels as prime95 and nicely logs core temps.

Note; Don't read to much on the absolute magnitude, bench system is using a 8800GTX -- king power sucker extraordinaire.

Quick question. you know how you have been saying phenom stability is hard to test well at stock clock (2.5ghz) and i couldn't remember wait the defualt voltage was for phenom so at 1.3Vcore and 1.35Vcore my phenom doesn't last more then 5mins large FFTs in prime. did i get a dead cpu?

more then likely you need to test your ram. i had the same problem till i changed ram. all sticks would test fine in single slot single stick tests. any slot any single stick. as soon as i would put in 2 sticks in dual or 4 sticks @ 1066 errors and lots of them. it would also error @ 800 but only now and then. changed my ram and all is good now. well so far anyway.

For a recap - what RAM were you using and what are you using now ...?

Got all my parts lastnight =) Everything went together easy and runs great. I ran 3d Mark 06 heads up Vrs a C2D Q6600... No contest. The Q6600 got slightly higher FPS in some areas of the test but the 9850 Looks sooo much better. Its smooth and clean where as the C2D almost felt muddy and skippy. I noticed screen tears all kinds of interesting things on the q6600 that arnt there on the 9850.. Ill post my CPUiD info later today once im out of work but as of right now im very very happy with what i got. I should have wrote the CPU info off the chip down before i pasted it and set it all up =/ when i switch thermal paste ill get all that. I have no idle issues that other people are having with DFI boards (im useing the M3A32-MVP Deluxe). More info tonight im going to see how far it will OC on my Zerotherm Nirvana 120 Temps are between 30 to 40c. 30 being idle and 40 being load. This is in a room thats runs about 65F with the AC goin. Anyways time for work. More info later.

Thanks for your post. I see the exact same things that you and Tony describe with the smootheness/quality but I'm not as good at articulating it.

[Brother Esau]

@Tony.....what are your thoughts on the 5/5/2008 Beta Bios as I have not really had time to devote to testing it adequately.

[SkullCracka]

For a recap - what RAM were you using and what are you using now ...?

i was using kingston hyper X 1066. may have been bad not sure. now using crucial ballstix 1066 no errors anymore.

still getting weird overclock, bad boots, lock ups ect..... but no mem errors what so ever in vista mem test and in memtest86+. gona reformat tonight and start all over. with the new ram 1 stick and 1 video crad and go from there. asus and amd blame bad vista install or vista driver issues.

so we will see.

Ok i found this to be interesting. Now. the DFI M2RS

Has 5 MOSFETs feeding the VCore, Mem Controler and HT Bus. Now the M3A32-MVP Deluxe


Has 10 MOSFETs 2 of wich are dedicated to the HT Bus and the Mem Controller. (some of the MOSFETs are covered by the copper cooler. Now i know this is an issue with AM2 boards not being backwards compatable with the new Phenoms rated at 125W. Im not sure what kind of impact this has but to me this could exsplain why some people cant Hit 3ghz. I dont think it has anything to do with the Chips or wich bin they come from. I just think that some boards are giving some people more power then others. If not more then more Stable power to the 3 given Draws. Might also be the reason that some people hit 3k. Run for a week, then BSOD like mad. If the cores are eating all the juice then the MC and HT Bus are hung out to dry getting what ever is left over. This would also exsplain at least imo why people are having so many stability issues. I could be wrong and i probably am ) Also i dont have any solid testing evidence to back this up. Just pose a question is more what im doing here. If this has already been discussed just ignore me

(sorry for so many edits :P i had the WiFi board pic up before. and im by no means saying that all Phenoms are exactly the same, some chips will do better then others.)

I'm not happy. Just killed one of my memory sticks. I got my Ultra 120 eXtreme in today, along with the scythe fan with 110 cfm. It just so happens that the ramsinks were a little tall for the hs's liking. I take part of it off... and it took off 7 of 8 ram chips on that side... Thankfully I have an old faithful pair of OCZ value 512mb sticks. Man... at least the cooler is a massive drop in temps, otherwise I'd be throwing stuff around. Oh well, just gives me a better reason to invest in some 1066 sticks.

Edit: And it even gives me slightly higher clocks, but that might also be due to lower clocking memory and less actual memory as well.

that is a question people area lready asking for a while and more or less the same with the 780 boards, i have the msi 790 k9a2 plat that has the 5 phase and asus m3a h-hdmi that has 4+1 phase, i started with the last board and all i can say is the mosfets run real hot @ stock.

I believe several people were already able to hit +3 on those msi and dfi boards with 5 phase

[Calcifer]

i am puzzled by my temps. they idle at 42c and load at 58. this is at 1.425Vcore and 2.6Ghz. thats high reight since the max temp is 63c. this is on a watercooling with 4x120mm rad's with antec tri cool fans max speed
