*Phenom II X4 9x5 OC Thread*

hmm i got a BSOD randomly while watching a video i wasnt even stressing the cpu hmm i think its was just a windows problem cause i ran prime95 for 10+ hours with out a single error, damn vista!

[j-dot]

I've got to 3800 MHz (19x) with 1.488V with a maximum of 49C on load of Prime95 for 10+ hours...i'm kind of cautious of running it 1.488V 24/7....is that a safe cpu voltage to run on? how much more should i try going with?

To get at 3600 MHz (18x) stable, I only needed 1.3750V, for the extra 200 MHz to get to 3800 MHz I needed to increase my voltages quite a bit...what do you guys think?

ARGHHHHHHHHH can anyone tell me why my temps are sooooooo high i hAVENT EVEN STARTED OC'ING YET IM ALMOST IN TEARS. just reinstalling EVERYTHING and had to use so buget thermal paste (almost liquid at room temps) i have a V.8 so i have a real nice machined surface anyways? i cant understand why its soooo GD hot! fans installed correctly (facing the right way)
should i run to the shop for so real paste or is there something much severe up?

for you people concerned about temps, as long as you dont go over 55c under prime95 load of an hour or 2 you are probly good. As far as voltage jump for 3.8ghz over 3.6, Yea I get the same thing. Its like 3.8ghz is a threshold for these chips and it requires so much juice to push it there. I have not gotten 3.8ghz stable under prime95 for more than 20 minutes. At 3.6ghz I can get prime stable for hours but it requires 1.4V core and 1.3v cp/nb. Its stable tho and thats what matters to me.

I will work on trying to get 3.8/4.0 stable this weekend.

Slappa was right, If things get out of control try working with the CPU/NB Voltage, a +.2V increase like he recomended yields great results for me.

Check ram stability. Also maybe try adding a bit of voltage to the CPU NB VID.

1.488 is fine 24/7 as long as you can maintain decent temps. Max is 1.55Vcore 24/7 but be wary of that amount. I personally would set your max as 1.5v.

When you get to the 3800-4000MHz range, you need more voltage, or substantially lower temperature to reach stability.

I would try wiping the paste clean and reapplying the heatsink/paste.

Yep. I experimented a lot and the CPU NB VID change was one of the most significant settings for OCing the chips.

Hey Slappa I need you to update my results to 18x/200 @ 3.6ghz. 1.40V CPU, 1.30V CPU/NB

Its is my best prime95 runner at around 95% Stability under max load for over an hour.

Nice, Will do when I get home.

I've been following this thread since it started as I'm going to AM3 soon and I wanted an insight on if I should and I noticed the suggestion/s of adding RAM to the chart and the reason it's not there as it's too wide. I notice the "Htref*multi", "CPU Voltage", "CPU-NB Voltage", "NB Clock", "NB Voltage", and "HT Link" columns are much wider than they need to be. You could easily fit RAM in there. Maybe not everything one needs to know about them but still enough to get an idea.

Thinking about doing this or creating a separate corresponding chart to go below it.

It may be confusing with 2 charts but then again, you wouldn't be limited like...at all.
