I just got my CPU up to 2.75ghz stable, according to OCCT. I think I hit the wall though. Load temps are at 48C and vcore is at 1.65, but I'm happy with it. Just need to OC my VC again and I'll get some benchies posted. I'll post some pics later.

Thats pretty high on vcore, you sure its not stable with less? Even if temps are ok sometimes a lot of volts can be harmful to the CPU.

It won't go stable with less, I tried. 1.65 is the maximum recommended limit from what I've read around here. Thanks for the concern though. <img alt="" class="inlineimg" src="/images/smilies/smile.gif" style="border:0px solid;" title="Smile">

I went back and changed a few things around. 1.65 is a little scary to run at on air and after your post acc, I decided it was best to stay within a 1.6vcore range, and go no higher. I lowered my multiplier and have so far gotten up to 2.65ghz, 265 x 10. OCCT Stable. ALso, in doing so, besides a 166 divider, I haven't had to change my RAM timings at all, from their stock 2.5-4-4-7, which has allowed a lsight improvement when it comes to AQ3.<br />
<br />
At 2.75ghz, 250 x 11, and RAM timings slacking a lot 3-8-8-12, and Video Card at 600/1600, I got around 72k, which I was highly dissatisfied with. After making the FSB, multiplier change, and reverting RAM timings back to stock, running at 265 FSB x 10, and keeping video card at the same settings, I got a 78k, which I am a little more happy with, as Im running cooler temps due to the lower vcore, somewhere around 45C loaded. This makes toad happy lol. When I get home tonight I'm going to try and continue cranking out more FSB until I hit that oh-so-familiar wall. <br />
<br />
I decided to start overclocking this now outdated CPU setup of mine again, as a result of not being able to complete a decent build until after my birthday in January. Taking the knowledge I have gained from browsing this site and putting it to use. Well...that...and the fact that I get very bored at home when my fiancee isn't there and there's nothing good on TV and I have no games to play that I haven't beaten.<br />
<br />
As always I'll pay attention to OCers nightmare, temps, and post benchies later. If anyone has a 3500 skt939, I'd like to know what they are running with it as of now, if they are still running it... Gotta run, at college and class begins in

somethign you might want to think of is loosen your timings on your RAM a bit and OC your HTT (fsb) a bit more. you get more performance out of having slightly looser timings w/ faster frequency. Lower your multi to 8 and up your HTT quite a bit.

Thanks mudd, I'll keep that in mind. While doing this should I keep my vcore at 1.6?

This is pretty weird...<br><br>
I'm in exactly the position as you, I built mine after my birthday in January too. I wouldn't call it an outdated CPU by any means, gaming wise anyway.<br><br>
My chip works like this (all are prime stable):<br><br>
1.4v - 2.4Ghz<br>
1.475v - 2.54Ghz - 46C Load<br>
1.550v - 2.66Ghz - 51C Load<br><br>
I haven't dared going any further... 50C was the limit for me. (And I can't afford a new chip for another 2 years or so, so I can't push it too far).

keep your chip below 50 all the way up to 1.6vcore but anything above 1.6v can have consequences on your proc

Way ahead of ya. I don't plan on going any higher than 1.6, as my temps were a little warm at 1.65, spiked at 50, leaving me with 1.6, and I'll make due with it, Im already testing 280 x 9 at 1.6vcore, if it passes, Ill keep upping it. Running a 133 divider now, timings at 3-4-4-10-2T. THis is rather exciting as before I focused solely on a 166 divider, stock timings, and an 11x multi.

what kind of memory do you have? if you have decent memory you can probably run a bit tighter timings w/ 2t

I'm testing now at 310 x 9 (2790mhz) If it passes, this will be my new highest overclock. Hopefully I can keep going, maybe...and i failed within 30 seconds, going to back off... to 305 x 10...anyway, only 5 mhz shy of highest, with about 50 on the FSB. If it passes this time, Ill start working on my RAM timings. Right now they are at 3-6-6-10-2T. Would be sweet if it could handle 1T, I'll have to try it. I'll probably have to up my vDimm another notch or two, probably hit 2.9. Does this seem reasonable, as this is the highest my bios will go? ANyway, Ill keep posted up on it.

I've got it stable at 330 x 8, 2.64ghz, and my Ram is 133, 2.5-3-3-8. I got a 78k in Aquamark, about to try Super Pi. Windows boots fast as heck now.

Keep up the good work. That processor usually tops out at 2.7-2.8ghz on air. You could probably get it higher if you removed your IHS since it would allow you to up the vcore a couple more notches. However since you can't get a new processor for some time you probably don't want to risk it. I was able to run my processor at 1.75 Vcore after I removed my IHS this was however on a socket 754 and they have a much higher stock vcore than 939s.
