Where i'm at currently with 2 cores....

EDIT: If anyone is interested... I've been at 2 cores for a while and tried to unlock the other 2 cores again (had them unlocked). I couldn't get them unlocked today.... i tried disabling the NCC (ACC) and re enabling... didn't work.... various things
then i tried turning the ram settings to manual and then i set them back and rebooted and 4 cores again!
weird.....

Yep, came from the factory with F5 on it.

Thanks, I am now @ -.075v on the CPU, still @ 3.4GHz & 2400NB w/ the NB @ stock volts...I also have the ram undervolted to 1.95v @ 1066MHz @ 5-5-5-15 2T, I think that's pretty good all around for everything IMHO. I am fixing to run some stability tests.

I had thought it was the memory because I had been getting random visual errors on screen. Like when I have multiple windows open, and would switch to a different window, the graphical interface with the other window would be distorted. I thought it would be related to either CPU, GPU, or memory. I was also getting memory errors with P95, and an in Windows version of Memtest. I RMA'd my memory, but it's ADATA RAM, so that was weeks ago when I sent it off, and still haven't even heard anything from them. Love the ram, it was great with my Intel E8500 setup, and overclocks really well, but their service is super slow, and they lack communication with the customer.

I could run IBT on high all day long, but P95 would always crash quickly. I also RMA'd the GTX 260 as well, because of heat issues and random artifacts. I have my 4890 in there for now since my i7 build is still a ways off from being complete. The new (or refurbished card) GPU from EVGA will be here tomorrow, over all turn around time of 8 days (including weekends) to ship them my card and get a replacement. Who knows, maybe I will get a free upgrade too! (I have a GTX 260 192, maybe I'll get a 216 lol )

I will post back some results when I have them. So far at idle if everything is accurate enough I am idling at 25c Of course it is night time, and it has finally cooled down in my house, but during the day, even with the AC cranked down to 65, my house's room temp sits around 80-85F... Gotta love central Texas heat...

I'm like HondaGuy, Shows just CPU and other cores are 0C. I'm using Everest Ultimate Edition.

Dopamin3

Newest everest works. I believe 5.02 displays the cpu temp right, but not each core.

Ok update... i got the 4 cores unlocked but everytime i start prime95 it locks up the pc. I wasn't getting that when i originally had the 4 cores unlocked...strange... i tried cpu volts all the way up to 1.5v and still got the same thing... also tried multiplier from 19 all the way back down to stock.... no love... so i'm back to dual core for now at 3.8ghz prime 95 went 3hrs at this setting earlier today. Stock volts...i have NCC on auto right now... if i turn it back to all cores, i will go 4 cores again and nothing seems stable on it now....

hmmm interesting... i got a good reading on the cpu from speedfan... but it is as you said.....only on the cpu not on the cores....

EDIT: DOUBLE POST.... SORRY! Meant to edit..... here's my sign...heh,heh

Well i messed around in the BIOS some more and was not able to boot into windows with quad core. Maybe I'm doing it wrong, I don't know, but I do know I am happy with this processor regardless.

So now I have it bumped with the multiplier once more to 3.5ghz. I am on the stock cooler and monitoring my temps and was wondering what is a safe temperature for your cpu to have? I am running P95 right now to test for stability with this OC and my temps are at the 44-48 range.

MrAMD_Fan

You are at 44-48c at full load? If so that is fine. You should be fine at 50c and under IMHO. Some people would say you could go higher but I like err on the side of caution....especially if you want to count on this cpu to last. I'm at 3.8ghz with and after market cooler and stock voltage. I thought my quad core unlock was fine but i can't get prime95 to run at any speed with all 4 unlocked...i'm not giving up yet tho! What voltage are you at?

Temps have been floating in the 46-48 range with occasional quick spots in the 49-50 range while prime95 running. Is that considered a full load?

I'm at stock voltage.
