Trying to OC an old Phenom II chip

post #1 of 12
Thread Starter 
Specs Here:

That is at base settings, everything on auto. I have also have a Ultra x4 750W psu. I know ****ty brand, but they've made some redeeming higher end models. Now onto some relevant info on my basic ***** attempts.


I got the BLCK to run at I believe 237 x 14 at the highest bringing me up to 3317mhz (why I lost 1 mhz, I have nooo idea.) This wasn't stable though and I would crash immediately after opening Prime95, or after a short amount of running a CPU intensive game. I lowered the BLCK to 235 and could run Prime95 without a problem. I've seen people talk about taking this chip to 3.5 and that's my goal, to get +25% our of this chip.

I tried lowering ram speeds, and messing with NB and HT speeds to no avail. There is one really strange thing that happens in my bios though, and it's this:


When the power settings on my motherboard are set to auto my bios says optimized. I turn it to manual and without changing a value I get flashing red NOT OPTIMIZED text but still POST. I don't understand this at all. I'm not even changing anything.

Any advice / help would be much appreciated.

(Sorry no cropping on the pictures, Imgur has been crap for me (chrome) since the update)



[EDIT]

I got the 3.5 after lowering NB and HT, and boosting core clock a bunch. It's actually stable and under load runs about 50C.

Going to try and bump down the Vcore tomorrow and see if I can save on some electricity.


EDIT 2: Going to stick with the 3.5Ghz at 1.425V Vcore. I figure it's old, I don't need to blow it up lol.

Thanks for the help? lol.

Seriously though, thanks. This forum (just not this thread) was great help.

Just loaded with unchanged Manual "Not Optimized" power settings.

Only changes are my +5V is .027 higher, and my +12V is actually occasionally bouncing from 11.985 to 11.925.

I was trying to use this guide before, but I don't entirely get it.

From what I've read supposed to lower my HT Link and NB speeds a bit, and then see how high I can get the BLC to go? Then try bumping other settings back up?

Sorry I'm so confused.

I seem to remember having a higher vcore on my old Phenom II chip. Somewhere in the 1.4's...

I'd give you some more info, but I've already invested enough time trying to figure out what the reddit post on the right is all about.... Doesn't seem to have anything to do with anything. Thanks for that.

You seem to be having better luck than I did with my poor phenom 2 945 "95watt".
Even with decent cooling and temperatures I would have to push more than 1.5v through the poor thing and to reach 3.5ghz and have it run somewhat stable the thing required nearly 1.6v but even then it failed to be stable as soon as temps reached 60c.

I wonder if I degraded the thing by running it for years at higher temperatures and even once on accident above 80c due to crappy stock heatsink that was at that time clogged with dust.

I'm sorry to hear you had such bad luck lol.

Also I have no idea what reddit post that guy is talking about. :/

3.5Ghz is a reasonable stopping point for a 925 on standard cooling. The 925 being a non black edition and earlier (C2) revision was never heralded for a big OC potential. The later revision 965 Black Editions were know for much more likely reaching the sought after 4Ghz.

I figured I wouldn't get 4Ghz, but I do suspect I have a decent amount of headroom left with the Vcore voltage. Thanks for chiming in!

Isn't that exactly why you SHOULD blow it up?

That's pretty good going for a 925. Most of them would have needed closer to 1.5v to get that high.

You could probably get a few hundred more MHz out of that chip, buy my guess is that you'd run into the voltage wall very quickly beyond 3.5 GHz. The lower-end Phenom II's usually had trouble too far beyond 3.5.

Yeah I figure I could get another 2-300MHz out of it, but anything >3.5MHz wasn't stable at 1.46v (I think that's what it was..) so I figured I'd reached a point of lowered returns and decided to keep the 3.5GHz.

If it weren't for my nieces and it becoming their Minecraft machine when I finally upgrade I'd probably consider pushing it to the limit, dance along the razors edge but I can't do that anymore. :[


ALSO, IS THERE A ZEN MEGATHREAD AROUND HERE? I want to upgrade sometime over the next couple months but I'd like to know if Zen seems worth waiting for.

And can I +Rep people for making me laugh? loll.
