Hmm what the heck, now this thing DOES boot when ACC set to 6%, I havent really changed nothing, only put some more clock to NB, memory, HTT and pci-e.

Btw, what does the CPU VDDA voltage do? Where should it be when overclocking?
And this still reboots if too much clock, tried 1.5Vcore, open window(freezing -8C outside..) and I put the 8-pin homemade adapter to the motherboard.. no effect :/

edit, some more to ask for, PCI-E watt limit.. at default its 25W ? .. what the hell is this, I tried 100W and all tests ran fine, but games usually goes to blackscreen and the graphics card starts to malfunction weirdly .. Allthought the comp doesnt crash, just the screen goes black(powersaving..)

Thats the Wrong PCI-E watt limit your adjusting.. The correct one will be preset @75watt...I believe its Lane #2 and #10..Just go throught each and only set the ones that ALLOW 16x. There will only be two lanes that run 16x.

NOTE:
In the same Menu pressF4 and 10 new PCI-E lanes will pop up on screen..

Two of those lanes Are X16lanes ...I set those to 200watts and AUTONONIMOUS.. I leave all other Lanes AUTO.

Also VDD is the BASE Volts for the Mobo.. The Higher You raise this the More Overall Volts you can achieve with VCORE and ACC.

I allways run @2.8v VDD.. 2.5v is default when on Auto.. Setting to 2.8v garentees that it wont Drop below 2.8v when overclocking..


.Also you Should Disable ACC and set 2.8v VDD for now and Manually Raise the Vcore For CPU/Nb slowly to see what makes its stable..This way you Know ACC isnt causing the Reboot...

Many things can Happen IF,,

If volts tooHIGH/LOW can reboot.
If CPU too HOT can reboot>
If the HT is too high it can reboot .
IF the NB is too High it can reboot.
If Ram timing is wrong can reboot.
If power supply is weak Can reboot..
thats just a few things to mention.

For a stock Phenom i would not use less than 500wattpsu that has a 8pin on it with at least 36amps on the Rail.

Try setting just the CPU Multi with Stock NB and NB 1.35volts ..On stock cooler you should be able to do 3.1/3.2ghz but will need to play with CPUvolts and Id use the 800ram or 1066ram divider if you have 1066..


P.S. BENBROWN
I use 1.68v CPU and 1.6v for NB while NB is @2000mhz for 3.52v.. These things like the Volts to somewhat be close together with the CPU bieng the same or Higher than NBvolts. For 3.5ghz with NB@2600+ i use NB@1.65v +2ACC . Now the sad part ,,just to run 20mhz higher i have to lower the NB to 2000mhz because this is my CPU's cieling no dout.

Ha haa how much do 45nm weigh?,, Santa's Sliegh with $h!tloads of them gonna be Heavy Eh

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
