Asus M3A79-T Deluxe

Very nice tips again! Thanks. Sorry for all these questions, have to learn .. things.. to clock..

But yes, the F4 would be the answer, I was trying to find those lanes which are in the manual too, but couldnt.. F4 solves this I think. So 200W for them and ACC off .. hmm Ill try. I have Arctic Cooling A64 Freezer pro doing the cooling now. Btw, new Enermax 525W Modu82+(3x25A rails) PSU coming this week too, maybe helps, maybe not, ready for CF then if not.

This Antec NeoHE380W has got some great performance in the past in some tests so I dont think its the fault now altought.. But never know!
It has 3x15A 12V rails .. not sooo bad, but if the phenom just draws some power what you can do. ..

But thanks very much.

Your Antec very well can be the problem..

380watts (9550 needs at least 400watts to work decent Overclocked minimum with Mobo and attached devices including a hungry Vidcard that uses PCI-E6pin..) Your Vidcard alone can eat 180watts ,,dosnt leave much for Devices and Mobo now does it

Okay, done AGAIN () some testing aaand:

ACC doesnt make a difference to the rebooting issue, it does it always when I go to 3310MHz and make it to run superpi, approx 10secs and reboot. Always, i tried 1.6 vcore, all other MHz to default except cpu, no difference at all.

Also it seems that core 0 and core 3 are the weakest one, core 0 starts to restart after 3200MHz. My best superpi run was 22.8sec at 3300MHz core 1.

Tried about every voltage setting and some other tweaks, Id say its the PSU now, or WALL(which I dont believe). It was little weird at first because I got the cpu to run superpi for about 10-20 times stable without acc, then I enabled it and it restarted again, then I put it off again and it still restarted, so dont think its ACC issue after all.

Also I noticed that running ACC on gets your memory benchmark results down a much (eg. read 8500 -> 8200, copy 10000 -> 9500, latency 50ns -> 53ns, also everests CPU Zlib 82600 -> 78000KB/s .. weirdo isnt it?) This affects to real life applications too by a bit. AOD benchmark gives better results too without ACC, and some variations are gone (examp:first run 9300, second run 8900, third 9200 etc, now its stable 9300 every run)


Better wait for the psu and try again, althought this isnt slow at 3.1GHz

BTw, this Antec could run FX-60 overclocked a much, 2x 1900XTX in crossfire overclocked, and still got juice, was getting about 500W off the wall tested by The Stilt if you know him. Dont know can that comp be compared to Phenom and one HD4850..

Hmmm my 6000+ @3.5ghz runs fine with a 500watt Antec and TA770. But once i installed the Phenom9950 (140watt) @3.2ghz and 8800GTS(G92)512mb..It would shut the system down..

I replaced it with a 650watt ThermatLake Modular which enable dme to Get 3.5ghz on SB600 and now this same PSU which runs My SIG.

Hey Man, even though you scare me sometimes with your voltage recommendations ... I have been paying attention to your suggestions seeing as how you get such killer clocks!

I'm on air, but temps never really seem to be too much of a problem, I did hit 60c on a 10 pass Linpack run, but I don't think that's extreme considering the load I was putting on it...

You may have seen this SS before, but this is my best stable clock using XP64. Even though it did pass 1hr Prime95 and a 10 pass Linpack run I still had to up the V's a little (Vcore 1.425, NBcore 1.325), due to a VERY RARE crash (once to be exact )...



Anyway, I tried for more tonight... I upped the Vcore to 1.475v and the NBcore to 1.375v (I also set VDDC to 2.8v) in Bios. My machine would try to post (not a hard crash) but kept giving me the F1 reset Bios error.

I have a decent PSU (see sig), but I'm really starting to wonder if it might not be enough to push those volts... Either that, or my chip is just a wimp.

What do ya thing?

TIA..... Dave
