Oc'ing a retail 3000 skt 939

[estew33]

Hi All,
I'm wondering if I would need a lot of amps on the 12v rail to oc this chip
Thanks

Actually it would be nice if some smarty pants can provide some information about overclocking the 3000 skt939. I am sure there are more to ocing this thing than just the 12v rail.

some questions

1. Can we oc with crappy ram (ie pc 2700) by locking the ram speed at 166mhz?
2. What is the recommended powersupply wattage, brand and various rail voltages
3. Safe load temperatures
4. How high should your HT be? 4x250 or even 5x250?
5. Heatsink! What is the best heatsink?
6. Best chip steppings.

I've heard that the 3000+ is a 75W chip. You can probably look that up... If so, theoretical peak demand on the 12V rail would be 75 watts, which is (using P = I*V, where I is current), just over 6 amps. The question is what video card are you going to power? If it's any of the 6800/X800 series, you'll want 420+ watts, with at least 23A on the 12V rail and most folks feel secure with more. I have a 500W Ultra X-connect w/ 34A on the 12V, and it cost me $99 retail. Rapid changes in amperage require quality capacitors, which are expensive. That's throwing in some advanced stereo theory, but it works for me...

1. yes, but you wont be able to push it very far.
2. your probably safe with 400+watt and at least 20 on 12v rail depending on your vid card.
3. 45c should be the load temp to stop at. if you hit higher than that, generally under load you gain 10-15c so...
4. HT is set to operate at 1ghz. HT is determined by taking your FSBxHT=1000. if you go above a thousand you have to move your ht down.
5. Zalman 7000 or xp-90 (or 120 cant remember which)
6. uh not sure.
