sweet result mate! Have you tryed taking them to 1800Mhz at them timing!

sweet result mate! Have you tryed taking them to 1800Mhz at them timing!
Mine sticks is Corsair but thx for the info i give it a try.Quote:

Awsome :up:
There we go...the WD2500JB refused to let the system work unless it was explicitly set to slave. Installing Server 2008 x64 and will have numbers soon.
Just playing with mine now.
M3a79T deluxe 0803 bios. Single 4850 gpu modded for low idle power. Water cooled.
For a quick start I used the bios settings from my 720 and trimmed back the multipliers. 3.8 looked ok in Prime as did 3.9. I could not get 4.0 to prime for more than 15 minutes so switched back to 3.9 for a while. As the 12v line was showing 11.6v I checked the plug in watt meter. For reference the 720 idles around 150w @ 3.8 1.55v, the 955 @3.9 1.55v is idling at 220w, up to 380w under prime :eek: As my Tagan psu is a 450w model and prime @ 3.9 has just failed at around 1 hour it looks like I'll have to break out the 750w Seasonic :eek::eek:
Silly power draw for 24/7 operation. If I can't get below the 180w idle mark at 3.8 then this chip will be looking for a new home :shrug:
Thats not a 720 Way to much volts.........the Phrase less is more applies here. I would start from scratch, when i got mine I took the same approach and was dissapointed. I took a step back started from scratch and was pleased....Quote:

Edit:
The above reminds me of booting an old 939 chip at 3.2, the Tagan roared. Who would have thought such a small piece of silicon could handle the best part of 430 watts :D
Good going Green team. Its nice to know future AMD chips will work on AM2+ boards. My 940 is plenty for now, but when these get cheaper, I will make the jump. Good results to everyone who posted info.
It's not much so far, but it's a start:
Anyone know if ganged is better for SuperPI?

I found it better in my test a while back on my 940.Quote:

What is a safe upper limit on the CPU/NB, for reference? Pretty much the same as the CPU cores?
Attempt #2:
Doing better, but still unganged. Having trouble with NB overclocking. The same question still stands for voltage, btw, if anyone knows.
http://www.pcrpg.org/pics/overclock/18.081.png
CPU/NB it was around 1.4 iirc on the previous PIIs, I think I remember gotVoltage at 1.5v, definitely worth a quick search on his user name.
The last time I enabled ACC to see what it did I discovered an extra core. No such luck this time ;) -2% All looks promising, +2% All looks promising, either appears to stabilise my cpu at 3.8 with 1.425v set in the bios - I'll investigate further. A short time playing with ACC is not helping at 3.9GHz and the slippery slope of more and more voltage looks unavoidable for the moment.
My 720 hit its sweet spot at the same frequency, something to ponder. 5:30am, time for bed.
+.250 to +.275 is max I would imagine for air, anymore just tosses way to much heat.......Quote:

1M Pi can not
I'll try a little more testing.
Voltage limit of NB/HT is the same as the CPU = 1.5v
Atleast thats AMDs "recommended" limits.
Have people tried OCing each individual core to see how far they go?
They don't all have to be at 4Ghz...
Perkam
lol
i can prime in vista 64bit for 15 min and i cannot get into xp 32bit at same settings? then i test best acc setting (rofl -6% for xp when for vista it was +6% before??), finally i enter xp, do some super pi, decide to reboot and set a little higher nb and it doesnt boot? cmos clear, afterwards acc on same setting as before no worky?
i went back to vista and to acc disabled for today xD
that rig is playing with me rather then the other way round... dammit.. try to find some good 24/7 first now ^^
Congratulations for the amazing results...i
Sorry to ask in this thread, but i have a problem to validate my results...
I tryed with many diferent clocks and times but isn t possible
http://i39.tinypic.com/2lbp54j.jpg
http://i41.tinypic.com/296n4zq.jpg
http://i43.tinypic.com/11gm6te.jpg
i can run superpi and pifast near than 6200 Mhz, and i noticed that have stability to validate...but i tryed and tryd (i give up...lol)
Another problem is...after i did try to validate at 6221 Mhz and is rejected...all the validations appear with 6221 Mhz (exemple...i did try to validate at 5500 Mhz and saved de cpuz file...but when i tryed to validate it validates (rejected) 6221 Mhz)...
Can somebody tell me what s happened?
Sorry the broken english and thanks for all
I think that this has happened before...
It's propably due to the fact that the boot speed and tha actual speed is very different, cause u propably used k10stat or AOD to reach that frequency.
I think chew has reported that, and he is more appropriate to answer.
Try booting closer to the validation u try, and do the last mhz with aod or k10stat. I think chew said once 400-500 mhz is the limit before cpuz rejects the validate. So booting at around 5.7-5.8 ghz should fix the problem. If that is possible, and if this is actually your problem.
I haven't figured out the magic either. It rejects tons of valid results from everyone. I've NEVER gotten a green submission, just yellow or red.
