5 Ghz P4 631 on air is this normal?

[davekusa]

I've had a 631 for a little over a year. P5WD2-E premium and PQI turbo.
When I first got it 4.5 Ghz (300 FSB) @1.42 Vcore was about the Max I got out of it. 58-60C XP-90C

I fold 24/7 so 50% CPU usage. In the last 4 months I also started folding with the Video card so 100% CPU usage. It slow started to go away had to lower the fsb to 290 then 285 then 270. I've been running 270 for the last 6 months. Finally complete instability. I was running stock 3.0 Ghz at 1.485 Vcore just to get it to work stable.

I'm really happy with it this setup and does everthing I need. I bought a new 631 for 70 bucks from ewiz (way cheaper than what I spent a year ago).

I figured this chip would perform about the same as my last 631. I saw someone at extreme system.org with one at 5.5 but I figured that was some uber modded board with 15+ volt mods and 1.8 Vcore.

I'm getting 5Ghz at 1.425 Vcore. I'm supprised and amazed at this chip. Is this normal? Is everone getting this kind of performance out of these or did I just get lucky with this?

mm well i did see a pentium for somewhere bieng overclocked to like 7ghz with like dry ice and all that stuff but that was not stable and such

btw whats folding ?? (sry to ask)

The folding program utilizes unused cycles of you CPU. I was leaving my computer on 24/7. So I figured it might as well be doing something usefull.

Very basic: We run computer models for Stanford university. They brake down these models into small work units that you can run on your home computer. The models are used for research in cancer and alzheimer's. When proteins do not fold correctly (i.e. "misfold"), there can be serious consequences, including many well known diseases, such as Alzheimer's, Mad Cow (BSE), CJD, ALS, Huntington's, Parkinson's disease, and many Cancers and cancer-related syndromes.


Each work unit is awarded points. Overclockers.com is team 32. It's a team sport.

These days its not that abnormal, but still a nice oc for sure. :beer:

[inkfx]

Yeah lately I've seen a few of these chips hit those kinds of speeds.

great OC man, whats she run superPI to a million in>? :)

Still more then a C2D im sure....

Round 26 secs for 5 GHz IIRC.

D0 stepping 65nm chips go like stink.

Here's mine, complete with 1M for ChinStrap:

Gautam is probably right @26secs for 5ghz.

[GigaHertzAddict]

That one fast chip.. I had a 2 Celerons D0 stepping too.. One did 5.2GHz the other did 5GHz. That CPU should fold like a beast...

[jordon]

the bus speed in that first screenshot is leet ;)

[davekusa]

26 seconds super PI. Ordered some new memory to help that. Backed down my OC to 4.7 to let the thermal paste seat.

[One Bull]

still a sweet oc :)

How does it Fold Dave?

Please post some WU times over in the Folding Forums.

I'm sure everyone would be interested about this.

Just for reference, my 930d did 4.8 on air http://www.ocforums.com/showthread.php?t=457919&highlight=wattz%27z

sweet
did you stress test it though ?

super PI 1 million 26 seconds. Folding GPU and CPU 100% at 4.7 stable
Will try to find time to flog it at 5 GHZ this weekend. New memory will be here on wednesday
