P4 2.4 or 2.8? c or e?

[VxD]

I'm building up a new system. One of my friends built a 2.4C system and overclocked the FSB to somewhere over 1000 such that he was running at 3.2Ghz on the stock retail heatsink and fan. I really liked his system...very fast and quiet on the retail setup.

Now I'm looking to build me one, however, I see most are recommending the 2.8c instead. Does the 2.8c yield the same FSB performance with stock retail heatsink\fan as the 2.4c? What is a fairly "safe" common FSB that the 2.8 is ran at?

Finally, I've seen nobody recommending the "e" prescott so I assume I should stick with the "c" variety...correct?

If it matters, I'll be using the Abit IC7-MAX with 2GB of Geil DDR400.

Thanks

"Does the 2.8c yield the same FSB performance with stock retail heatsink\fan as the 2.4c?"

In most cases, usually not. Remember that every single chip is different, and will overclock differently. With a retail heat sink and fan, most 2.8C's will go to about 3.2-3.3. I just finished a water cooling rig for mine, and I am at 3.57ghz.

"What is a fairly "safe" common FSB that the 2.8 is ran at?"

Im not sure what you mean by safe, but usually somewhere between 230 and 235, on average.
Remember that cooling factors(or lack thereof) will greatly impact performance.

Finally, yes, I would stick with the "C" model, unless you feel like waiting another month or so when the new Prescott stepping comes out. As of now, the 2.8E runs significantly hotter than the C model, and the performance is basically the same. The E model will probably achieve a higher overclock, but one needs at least a water cooling setup to even think about that. Hope that helps, take care.

Yes, your post helped a lot. Although I'm still not sure if I want to go with the 2.8 or 2.4. On one hand, the 2.4C's seem to reliably run at 3.2 (with stock cooling and high speed memory) with such a high FSB. On the other hand the 2.8 seems likely to run at 3.2+, but the FSB would be lower.

Any advice on one over the other?

Thanks in advance,

Down with the space heaters!

Well that is unless you are an overclocker then you might want a space heater for a CPU but other then its OC ablity the Space heaters suck compared to the P4c and personly I like to keep my computer as cool as possible and as quite as possible even when OCing.

Check out the article on hardocp.com re: Overclocking the Prescott 2.4a before making a decision.

Those chips are cheap and appear to overclock very well. You would also be able to use a lower speed ram like PC3200 to oc this one, since its FSB is lower at stock speed.

Yes, that is the dilemma. I chose to go with the 2.8C cuz I had good air cooling, and now water.

The price is so close between 2.4C, 2.6C, and 2.8C, i think your crazy not to take the 2.8C. Faster stock speeds and a higher multiplier for high OC's without outrageous fsb settings. Sure the increased fsb adds performance, but also heat and is more demanding on the chipset and memory. The 2.4C was the killer chip back when they were priced 2.4C=$175, 2.6C=$225, 2.8C=$275, and 3.0C=$375. Why spend more back then. But now 2.8C is priced right. It's priced = 2.6C, enough under 3.0C, and barely over 2.4C.

Tru dat.

I'd go with the 2.8C. To get a 2.8C to 3.2GHz takes only PC3700. To get similar speeds from a 2.4C you'd need at LEAST PC4200. Look at the price difference between those modules.

This assumes you actually want the performance of synchronous clocks.
