San Diego 3700+ @ 2.7ghz... higher?

[DaveUK]

Thought I'd tinker with overclocking a little.

I've adjusted the DDR frequency so that with the FSB increase the sticks are sitting at 193mhz (if I choose the next RAM stepping they go to 225mhz (450DDR) which at my timings they dont like).

My CPU is now sitting happily at 2.7ghz / 245 FSB @ 1.45v (San Diego 3700+ w/ Thermaltake Golden Orb). Idle temp is 43 degrees.

Memory is 193mhz 2-3-2-5 1T (OCZ Platinum DDR-400)

Can I go higher? My decent RAM has the headroom to get to 260 with these timings (RAM frequency would be about 215mhz) but I don't want to nuke my CPU. 260FSB would take me to 2.86ghz which is a full 30% overclock.

Anyone got experience of overclocking this CPU on air cooling?

hmm... ive had no stability issues whatsoever with the past couple of days gaming etc, temps haven't seemed problematic.

However, I just tried Prime95 for 20 minutes, and the temp rose to 54C and stayed there. Doesn't look like its gonna get any higher, but does that seem safe to you guys? Or do you think that I should try dropping the CPU voltage to 1.425v and see if it remains stable?

Chassis temp is 39C (its a hot room).

I have a 3700 san diego in my other machine. It ran at 2.75 @1.5v with temps of around 58c. Thats as fast as I could get it to run. I run it at 2.6 now with no voltage increase and load temps of 46c. I would keep the temps below 60c. Also I use a thermalright xp-120 heatsink. If you are running the stock one a good aftermarket cooler could help get them temps down.

I have a Thermaltake Golden Orb

OK, now 2.7ghz @ 1.425v and hitting 53-55 degrees C with hardcore prime 95 sessions - im happy with that lol.

FX-55 speeds will do my just nicely for the time being with my X1900XT.

It will hold me until my next build, which will probably be in about 6 months time with Conroe E6600 oc/DX10 GPU+Vista.

I think the fastest CPU AMD makes is only 2.8 ghz so I would think that cpu should do quite well for some time.
