Undervolting

This thread, here is solid proof that my processor sucks at OCing so I'm not even going to bother. However, I've begun to experiment with dropping voltage below standard in hopes of getting lower CPU temps. Is this sound reasoning or stupid? System is stable @ 1.475v (stock is 1.500v).

Go for it... Just keep checking for stability!!

yeah stability is the key.. I'm happy on my notebook after dropping the CPU voltages down to .7V whenat idle and using light apps.

Interesting, I dropped volts as mentioned above, but I saw temperature increases on idle. What is this?

Undervolting has always dropped load temps for me. For a long time, I ran my chip (3000+ Venice) at stock speeds with 1.15v, and temps were down almost 8c durring load.

Now I run 280x9 w/1.375v. 8)

I'm not sure? :?

Not all chips are the same... Some freaks are made now and then ;)

Yeah my chip is freaky. It just gets uber hot when I apply extra volts, it won't OC. Crashes every time.

I read some of your posts over in that other forum... they said your proc was some weird sku??? It was only released for a short period or for oem or something???

Mayby thats why they were pulled by amd..?

It's a 3400+ (939) --> from the link he posted, that forum said

Yes, the 3400+ (939) was meant for OEM only but was sold by retailers. I wouldn't say short lived as Tiger Direct was selling them just a few months ago. And for a very resonable price to.
I don't know anything amd (yet), but mayby Sovereign can answer to clarify??

thats an insane overclock for such small voltage.. is this prime95 24 stable?

Yes, but I trust BF2 a lot more than prime. I can run 2.7ghz @ 1.5v, prime stable for 7 days, but BF2 crashes within half an hour. Battlefield 2 stable at these closk.

I purchased the 3400 939 with a bundle at TigerDirect. It consisted of an Asus A8V Deluxe, Soyo Dragon case, AMD64 3400 939, cheap speakers, a Dragon optical mouse and a keyboard. The bundle was notorious over at AMD's forums for "RipOffDirect.com" pulling a "scam" because many of the systems built with this kit refused to boot. There was a BIOS issue that was corrected on version 1009
