Well, AoD disappointed me because it messes with my Bus Speed, even if it's set to 200 in BIOS, it goes to about 201.5 and that results in odd clocks, which are not what i've stress tested. This also happens on my UD3 if I set the BUS speed to Auto in BIOS, so I have to manually set it at 200 to actually have the clock I need.

On the other hand, I've been using AMD PSCheck for a few days and I must say I'm most pleased with it. It helped me solve my temp problem by intelligently managing power states. I'm using the following config:
LLC - Ultra High
Pb0/Pb1 = 4500 @ 1.4v - I've set them both the same because Pb0 is hardly ever triggered for some reason
P0 = 4200 @1.325v
P1 = 4000 @1.3v
P2 = 3000 @1.175v
P3 = 2000 @1.025v
P4 = 1500 @ 0.875v

My PC stays at 4500 turbo speed most of the time. When under heavy load it throttles down to 4200 and when under extreme load it goes to 4000 (as opposed to the default 3400 P1 power state which was quiet the jump down and may result in performance spikes). With these settings my temps, under any kind of load, never went above 53-54c on the cores, normal gaming use they max out at 48c but average around 42-43c. trimmed (Click to show)
No crashes, no freezes, no system hangs, so far it seems totally stable and I've ran a series of stability tests, individual settings for Pb0/1, P0 and P1 have been tested 8+ h in Prime, didn't really stress too much about the others but they're pretty close to stock values so they *should* be fine. No issues in benchmarks either. I've played FarCry3, Hitman, some Need for Speed and Dishonored, like I said, no stability issues so far.

To this point, I would warmly recommend PSCheck to anyone that wants a flexible CPU OC and the chance to keep temps in better check.

This is not exactly throttle. This is how turbo works. I don't really see why you insist in using Turbo while you can get your CPU to run at 4.5, 4.6 24/7, and even get working C1E/C6.
Second thought: Your pc usage is probably a lot different than mine, which could explain where you benefit from this. In my case, Turbo is just a stability issue, since whenever my clock matters (compiling, folding), turbo will not kick in.

I'll be swapping out my 1055t to a 8350. What free benches do you guys recommend that I run to compare?

Guys, I've ended up buying 2400 Mhz G.Skill RipjawsZ 10 12 12 34(2 x 4 GB). I am pretty stable at 4.7Ghz @ 1.43. Now, my question is am I going to be able to be more stable at 5Ghz if I lower my memory down to 2133, because right now I overclocked NB/HT to 2400 as well.

No. Ram doesn't impact stability for the cores for me. Got mine running DDR2400 9-11-11-25, lowering ramspeed and CPU-NB doesn't net me more speed on the cores nor more stability.
post #7957 of 67241
Okay, thanks, can you please give me any hints on which timings I can try on my memory to speed it up even more a little bit? Thank you in advance.

I have tested a bit power consumption of my new FX 8320. I must say, its pretty good. In Cinebench @ 4.0Ghz 1.264V , the system consumed about 160W from the wall. At 4.5ghz with 1.425V in Cinebench, consumption was about 210W from the wall. Temps r lower for about 6C also.

1.86 v is Not the default for this CPU for cpu-nb .It is actually better not to go over 1.25 v if you can manage it. I have rarely seen high cpu-nb voltages adding to system stability au contraire. I set mine at 1.225 volts.

PCMArk, Cinebench, Sandra

coming from an 1100T you are not going to notice a difference at stock 8350 compare to a OC'd PII but all i had to do was bump up to 4.4 (not really any voltage was needed) and my scores where higher.. I wish I had a chance to run a full suite with them side by side with the same setup but i didn't get the chance

I will have to say there is no cpu.nb bottleneck in the chip and it loves fast ram with tighter timings
