Asus M3A79-T Deluxe

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..
