Ok, thanks.

Orly? Is there any harm increasing the power that gets?
Where did you read that at? Are you talking about what the default voltage AMD sets them at. They were two 9750, one 95W and one 125W. The 125W default was between 1.2 and 1.3V. On a 95W the default was between 1.1 and 1.25V. A 9750 was never that good at overclocking, but your not going to get to far a 1.25V.
If your using a stock cooler your pretty good up to 1.35V, but just keep a eye on your temp.
Yes it is ok, going above 1.25V isnt going to damage anything, 1.25 is within the processors default voltage. Even if he has a stock cooler and half ass case cooling he is good up to 1.35V
How are you planing of getting a good overclock doing that? And it wasnt Gods idea.
Correct.

I'm gonna try that on my Pentium 4 OC rig later this week. I've bumped the voltage all the way from what I think was stock (1.4v) to 1.4375v and it wasn't stable at 3.4GHz (it's a 2.8GHz Pentium 4 520 E0 stepping.) I've actually bumped it up to 3.5GHz at 1.4625v and it seems stable, but I haven't gotten a chance to Prime95 it yet. I'm worried about the Northbridge temps though, since I'm getting low 50s, I think. how high can those things go? I have a couple really tiny fans laying around that I might try to tape on with double-sided sticky tape.
To answer your question, though, as long as your temps are good you should be able to raise your voltage a good amount higher than stock (just not ridiculously high.) I'm not sure what that threshold is, though. A bit over .1v, right? You can raise it higher if you want to cool it below freezing, though.

sorry, i meant the recommended MAX voltage. i figured he meant 1.25 or whatever he said was the max. i guess i should've looked it up.

Well I don't know much about AMD's but he said he read it somewhere that those were the max voltage so I told him the safer answer?

I have tried increasing the fsb previously and have gotten up to ~2.8ghz stable at "auto" voltage. I have the voltage manually set at 1.25 volts at the moment and am slowly increasing the fsb again. I'm also running orthos right now and am only getting ~31c max temperature (overclocked from 2.4 to 2.63 so far). I have an Antec 902 with the extra fan installed as well as the Thermaltake Big Typhoon (http://www.newegg.com/product/product.aspx?item=N82E16835106061). Temperatures are not a problem. I'm also looking for the AMD webpage where I read the specs, I'll get back to you guys if I can find it.
EDIT: I have found the webpage: http://products.amd.com/en-us/Deskt...3=2400&f4=&f5=&f6=&f7=&f8=&f9=&f10=&f11=&f12=
Apparently, a few months ago, I read it wrong. It seems like 1.3 volts is fine. I'm gonna put it to 1.3 until I can find a credible source that states I can go higher.

Okay, I've been working with my cpu for a while now, and have gotten this far:
I'm running Orthos (stressing), Coretemp, CPU-Z, and Firefox right now without any problems. Temp is at 36c right now, obviously not a huge change. I'm gonna hit the sack and finish this tomorrow, wish me luck.
EDIT: About 30 seconds after closing Firefox, Orthos gave me this:
Not a very fun message to receive. How do I read this "stress.txt" file? I dunno where it's located.

Like I've said before, a 9750 isnt a great overclocker. 3ghz. is really a pretty good overclock for one. Your not going to get any further without bumping up your CPU voltage and NB and the CPU NB voltage. Unless you set your HT and memory back, but you still need to bump up your CPU and NB voltage. Just running 1.25 on your CPU isnt enough voltage to get you any higher.

I did stress it.
Well, yeah. My goal from the beginning has been to get it to 3ghz. I'm at 2.962 and running smoothly. Hopefully it will be stable at 3ghz. I have the cpu voltage at 1.35 volts, and that seems to be enough for now.
