Ocing Athlon 3700+. I'm starting to wimp out at 2.7GHz!

[rHy0]

I have had my Athlon 3700+ (stock 2.4) at 2.72GHz for a couple of weeks and so far after a good few attempts I have not been able to succeed in anything higher. I crash at 2.75 (250FSB). 2.8GHz would be a dream to get, however although I may be able to get to that with more vcore and extra ram voltage, I have been putting it off cause i am nervous I might mess up my system at any higher voltages... Right now I have my CPU vcore @ 1.50v (cpu-z, speedfan report 1.53...) from 1.48v stock, ram and everything else is stock voltage.

My memory (see sig) is at timings 3-3-3-8 (1t). 333Mhz.

HT multi set at 3x.

My CPU cooler is a Zalman 7000B. Temps - 26C idle/45C load.

As I have said, I would love to get 2.8GHz out of this CPU safely but I am not sure if it's wise for me to raise the vcore anymore for fear of a total system failure... Can I up the vcore more safely? Should I even be thinking about attempting 2.8GHz with my hardware? Plz enlighten me so I can finally make a confident decision :)

Thanks.

Try lowering your ram speeds. Or increasing ram latencies to be more relaxed.

I had mine running at 2.8, but could only do it lowering my ram.

Yeah I have already tried lowering my RAM speeds to 3-4-4-12 but still failed prime95 at 2.75 (1.5vcore). Also crashed and wouldnt boot into windows.

No, he means to put a splitter on it so that your ram isnt running at 250, but instead 200 or something like that.

2.75 is the highest for most San Diego 3700+ CPUs, which is plenty enough.

Highest! Really? Dam I thought I could get much more out of it... I am at 2.72. I have definately known ppl who have their 3700 @ over 3GHz. Obviously very good stepping, but I also see alot of ppl @ 2.8...

Can ppl who own an Athlon 3700 post up your OC, along with your mobo and ram info if possible plz.

2.75GHz yes with air cooling 2,9Ghz for water cooling and 3GHz for extreme cooling.

Mine was Asus A8N5X, Thermal Take Silent 939 K8 Cooler, and mixed ram.
1x512 333, 1x512 400, 2x256 333. All Apacer tho.

I was running at 2.8
