AMD FX-60 (CCB2E 0608EPDW) Overclocking Help

I tried 15x on the multi with the voltage at 1.5Vs and it booted up til before the Windows load screen then it just sat there... darn it LOL I want 3GHz. I know my cooling can handle it cuz it did on the Asus board, it just wasn't toally stable cuz I was limited in voltage, I think I need more than 1.5 for stability at 3+GHz

Any advice on how to get 2.9GHz stable? I hit 2.9 the other day stable enough to run Aquamark3, but when I remembered I'd had my LDT on 3 instead of 5, I reset it to 5 and it wouldn't run it anymore.

 

I'm thinkin' maybe leaving my LDT at 3 even when I'm not OCing enough to do that yet, or maybe 4, will make the difference. Will try that tonight probably.

Has anyone that has two 7900GTXs ever run a spread-test of resolutions on 3DMark06? I bought it because I wanted to be able to play the demo full on (1680x1050 or 1920x1200).

 

I did that this morning after benching my system in all the individuals (AM3, 05, 06, Oblivion), here's a chart I made. Top is resolution, then total score and so on. Keep in mind this is at total stock, nothin' overclocked at all, if I was OCed to as little as 2.8GHz or even 2.7, I'd be getting higher scores by a few hundred at least in all categories I imagine, as I've said, I have nearly cleared 10K at the "Default" settings for 06 before. Anywho, here's the chart:

I think it's funny that all the other tests kept goin up or down yet GT3 just kept goin up and up and up lol I can't wait til I get that 640x480 score at Default resolution after I get this baby stable at 3GHz, which I AM going to do LOL I don't care if it likes it or not. ;)

On the FX-55 I am running it at 245*12 LDT4 @1.4V. My LDT is 1.3, chipset is 1.6 and my DRAM is 2.7V. Give that a shot and see if you are stable.

Well, I didn't try anythin' like that but I DID get 2.9GHz stable.

 

Settings are (I'll have to check to be sure) like so:

That gives me 2.913GHz according to CPUz. I benchmarked it with everything from 3DMark01SE to 03, 05 and 06, as well as Aquamark3. Even did a spread-resolution test on 06 ranging from 1920x1200 down to 1280x1024 to make sure it was completely stable, got some very impressive scores seeing as I haven't broken 2.92GHz yet and my previous high scores were mostly at either 2.928GHz or 2.945GHz, and I'm already within spitting distance of those numbers.

 

I would post the screen caps but seein' as I'm probably gonna OC even more, I'll just keepin' in storage for knowing what scores I should get if I have to reset my CMOS and re-overclock to 2.9 lol

Welp, 3GHz was a bust again. Tried as high as 1.55Vs and it still froze in the last test of 3DMark05.

 

I'm back at 2.9GHz.

 

I'm thinking maybe I'm gonna have to change my FSB offa 200 to get 3GHz stable, cuz obviously just upping my multi is not makin' everything happy slappy LOL

By the way, 3dmark benches are fairly poor indicator of stability. GO straight to dual prime after it passed dual superpi and see what a real stability test yields. (Sadly I don't think you'll like it.)

I hate to say it, but if it's stable enough to run Oblivion, I could care less whether Prime95 thinks it's stable, but when it can handle 6 hours straight of benchmarking I don't think Prime95 is gonna be any problem. And I don't have SuperPi.

 

I'm happy at 2.9GHz, but I will try to get 3 again sometime soon, probably by way of 250x12 on the CPU with the LDT down at 3x. Running it at 4X right now I think is the only reason why I'm not unstable.

I'm runnin' Prime95 as we speak at the settings in my sig, just to see if it's gonna be all gravy or not. Doin' a small FFT test like it's said will test the CPU best, one on each core... been running for a bit now and I"m barely seeing 40-42C, just started Test 2.

 

I think whoever thought my OCing being flawed because of my temperature getting to high needs to put their foot in their mouth ;) LOL

 

 

ADDED IN BY EDIT 1 HOUR LATER:

 

1 Hour of Prime95 and I hovered at 40-42C the whole time, very very occasionally touching 43 for a brief second before dropping back to 40C. Definitely rock stable me thinks. Just wish I was at 3 instead of 2.9 ;) LOL
