Bitten once more by the OC bug

As you can all see in my sig, I run at 220 x 11 (2420MHz) usually. But what I never did was optimize the temperature of the CPU by playing with the voltage.. But I'm getting around to that now.

217 x 10.5 = 2280MHz, but check the screenshot for the required voltage. :D I basically work the FSB up 1MHz at a time with the nf7vcore program and then run tests. If it passes, I move it up another megaherz, and so on until it freezes. Then I go into the BIOS and set the last good FSB and increase the voltage by .025. Then I repeat the process.

The processor is currently at 38C full load. :D

    That's pretty sweet... my voltage must be at least 50% higher for a much more modest ol' 1700+ DUT3C overclock in the 2100MHz range (used to be 2.2 to 2.25GHz). So I hope we'll see some real high clocks there as you bump that voltage up! Not that there's anything wrong with 2420 :)

    PS- Interesting process also, I'll keep it in mind if I get my hands on an nVidia board.

    I forgot to note the chip! The venerable DLT3C/JIUHB 1700+. Can't remember the xPMW suffix or date any more.

    This chip is over two years old (Bought it on 8/12/2002 from newegg for $58 shipped); it's my baby, the Winbond BH5 of CPUs, kicking the collective asses of Bartons and Mobiles!

    Gotta love those 1700 DLT3C's, I retired my pair a while ago, sold one but kept the other cos, like you, it was a love affair. All I need now is to be able to afford a new case & motherboard then she'll be folding once more full time.

    38C @ full load is a fantastic temp, whats cooling it?

    Thermalright SLK-947 and a SmartFan II running at 3/4 speed (As far as potentiometer positioning). I think I'll just drop it to half-speed, as I only pick up 4C, and loose a nice chunk of noise.

    Ah that'll explain it then, I know what you mean about the noise, my smart fan has an annoying pitched whine at higher speeds which means I dont use it.

    Actually, the noise at full speed doesn't bother me a bit. It was running at full speed for over 18 months. I figured I'd just turn it down because the CPU isn't even breaching 110F.

    Unfortunately my pc's reside in my lounge which means that my other half complains if I turn up the noise. Therefore everything is geared to low noise, on my next rig, when I bring my 1700 out of retirement, this wont be a problem as it will live in the study & have a wireless connection. :)

    Anyways, back on topic, is this the cpu that you burnt in for ages? If so is the goal to get it back up to it's norm operating speed (2420mhz) at the lowest possible voltage or to get to the highest possible speed at specific voltage/temp?

    Ah yes, back on topic. ;D

    My basic goal is to once again return to 2420MHz with the lowest voltage and temperature I can stably find. The chip's upper limit is 2450MHz, so there isn't much else to shoot for. :\

    Yeah. This CPU was burned in for 20 months to hit 2420.
