what do you guys suggest? I dno't wnat to dump too much money into a system like this because it's not exactly cutting edge even though it still performs well... tuniq tower?... also considering lapping the heatsink since I heard the core 2 s and onward all the way up to the i7s have horribly concave or convex heatspreaders

I would suggest you first try and see the best you can do on what you have. If you feel that you are being limited due to temps then upgrade. Otherwise just stick with it.

yeh i'm in the process of doing that right now.

temps are

73/73/71/70

with max of

77/75/73/71

on all 4 cores (0-3) after about 30 min of "max heat" on prime 95...

... hta'ts at 3.2ghz 1.385v so yes... my heatsink appears to definetly falter here... I originally got it when I had a p4.. then got a dual core opteron... both cpus weren't nearly as hot as a quad core.

I'm thinking of lapping first and then seeing where that gets me... I'm not too interested in goin gwith more exotic cooling unless that involves water + CM cosmos s..... I've been wanting that case for a while but idk...

Try running a higher multiplier and lower FSB... will take less voltage and you will probably get a higher clock with ease. You will also lower your temps. Not sure how your motherboard works... but on mine 400Mhz FSB is the highest stress point... at which point 401Mhz goes into different timings and the NB becomes more stable. However, it runs faster below 400Mhz FSB unless I somehow manage to get it stable at a FSB above 420Mhz.

interesting how you can even boot between 350-400.... there's a nice fsb hole there and mine won't even boot in that range... i run 401x9 24/7 at 1.5V (actual) on an ocz vendetta 2 cooler

Mine boots without issue... although between 391-400Mhz it takes quite a bit more voltage. 100% stable at 390Mhz on the FSB for me though. I was also surprised because I read about that FSB hole on this motherboard The system is faster and more stable for me at my current setting that when I was running 3.6Ghz and above 401Mhz on the FSB. Go figure? lol. I am only running the NB voltage at 1.25V too!!! Maybe I just got lucky...

Thanks for all the comments. I'll definetly keep them in mind when I start to explore other overclocks. I didn't know some boards had a hard time at the 400mhz mark.

I guess the whole reasoninig behind that was to get the memory running 1:1 and try and get it stable at that fsb and hopefully step up to a 9x multipler without having too much issue. I'm probably going to try what you guys said though and start backing off on the fsb and go back to a 9x multipler... thinking I might back off on the voltage too.

I started a stress-test on prime95 this morning before I left for work.... it's been on 5 hours so far and I haven't had a chance to see if it's still alive. I did notice the core temps were peaking very high so more than likely a lapping or new heatsink is in order.

I really appreciate the comments though! I'll report back when I get home if it's stable or not. (3200, 400x8 @ 1.385v)

You might gain more speed running at 1:1 ratio at a lower FSB with a higher Multiplier anyway as your memory timings will tighten

Good point... I've never had good luck with my memory but i've been on KVR DDR400 for the past 2 builds which really really held me back alot.

So far I'm 13 hours prime95 stable at these settings (400x8 1.385v).... but I don't think this is where I want to stay anyway... ultimately the goal is 400x9 @ whatever voltage is comfortable but I'll try what some of you suggested here.

Probably dropping down to 377 fsb and 9x multipler for 3.4 and try that out next.

btw, 1.2 is my current NB voltage (i think) does that sound about appropriate?

1.2 is pretty low for that FSB... then again you are P45 vs. my P65 so maybe it runs on less voltage that high and its normal. Maybe someone else could answer that one I happen to be running my FSB really high on only 1.25V but most on my mobo this high run 1.35V or 1.45V.

nice... my NB voltage is 1.45V... it's been like this for more than 2.5 years since I bought it
