Good final overclock?

[InorganicMatter]

Sig. Just started Priming, so far so good (passsed 1024K test). Only two things concern me:

1) My CPU is at 65C. I realize this is still in the "semi-safe" zone but how dangerous is 65C?

2) Ther are occasional short funny buzzes coming from the hardware (the actual PCB, not fans). What are these? It sounds almost like it's coming from the direction of the RAM, and seems to happen if the activity LEDs are pegged. Not doing it now, but it concerns me nontheless.

I don't plan to run it like this all the time, most likely only when I go to encode a video (+700MHz helps a lot with that).

Hmm...there goes that buzzing again.

EDIT - Yeah, definetely the RAM. The activity LEDs will be low, then suddenly they will peg out and drop back down very[/b] quickly. When they do that, there is a slight buzz.

I didn't think a thermonuclear P4 could be run without heavy water cooling or it'll melt down. So 65C is great by comparison! lol

I don't understand. Is this a groundless flame against the Prescott's slightly higher temps? At stock mine idles at 38C, so I really fail to see your point...

65C ouch, i wouldn't run that hot.

Yes

j/k, 25% overclock seems pretty good, especially on the hotter (you know it to be true) Pentiums on air.

Idle? What's that? Oh yeah, it's when your system is still loading the Folding@Home program.

Seriously though, nice O/C. Don't take me too seriously. But 65C is pretty hot, you'll definately be reducing the lifespan at that temp.

The IC7 and IS7 read CPU temperatures much higher than actual. My IC7-G reads the temp on my Northwood about 8-12C higher than actual. And my IS7 reads the temp on my Prescott about 6-10C higher than actual.

Your temps are probobly within 55-60C which is much safer.

Make sure you're running the latest bios revision, I think there was a revision where there was an updated calibration for Prescott CPU's.

58% is even better

nice oc, to bad it would take like a 5Ghz to keep up with a 3ghz AMD

The CPU cost me $50, and the entire system that its in is scraps. The HSF cost me more than the processor.

Um you should not talk about AMD, as Pentium M's own you!!! 2.795ghz and 26s 1M superpi is hard to beat when your talking performance per mhz! Dothan's are one damned efficient processor!!!!

Well, considering that I got my motherboard, RAM, and CPU all from work for free (I love my job) your argument is null and void.

It's weird, but I get that same electrical hardware buzzing when running 3DMark05. While the individual tests are loading I hear a particular buzzing sound that comes from the CPU/memory area not the hard drives where I'd might expect it. It is unusual, but you're not the only person I've heard of noticing this phenomena. I would assume the cause may be a portion of the power handling circuitry such as an inductor coil for instance. With a large current / power draw this seems possible. Listen closely to an AC power adapter, those transformers often buzz like crazy. Damn my acute hearing.

I think I may start a thread on this....

EDIT: my hardware is AMD based. Just FYI

It's more then likely that you're right. One method that's worked for some people is a dab of hot glue.
