Bst Ocing P4

[TheFrag]

I am new to Intel and was wondering what a good OCer chip was? I am loooking at his one http://www.newegg.com/app/viewproduct.asp?description=19-116-137 How high should it be able to go? What is the multiplyer locked at?

To find the multiplier, you look at the FSB, which is 4 x 100 on this chip. Divide 2400 mhz by the 100 mhz fsb to get a multiplier of 24 (locked).

I dont have much experience with 400 mhz FSB p4s, but with the 133 FSB northwoods, with decent cooling, 150 fsb stable (completely, 100%) is almost always feasible. So if we say the 2.4 chip you're looking at will be about the same, and be stable at say 130 FSB, it'd do 3120 mhz. You may luck out and get a chip that will reach a lot higher, or you may get a crap chip that wont go far beyond 2.6. I'd put money on at least 125 mhz fsb stable on that chip (in a good mobo)

then what is a good chip?

If you are going to go with DDR ram then the lowest multiplier, either a 2.26 (x17) or 1.8a/2.4b (18x). If you run RDRAM, then a higher multiplier might work better, since you wont have as much head room to overclock the FSB and RDRAM can be more difficult to hit higher FSB with.

If you are wanting to go with a c1 then your options decrease alot, at present I have not heard of any 2.26 c1s. The only 1.8a c1's have been OEM chips out of Dell machines. The 2.4b c1 is the only retail chip that you can find out on the market. You can gamble and hope to get one from newegg, but they still seem to be shipping b0 chips still. 2 places in the US that can guantee you a c1 that I know of are pcnut.com and atacom.com. I just ordered a 2.4b c1 from atacom.com. Before some one points out there low retailer rating. I have purchased a chip from them in the past and had no trouble. They went to the stock room and told me the pack date and fpo/batch numbers on the box before I ordered. I should get it next week some time. I will let you know how it turns out. Depending on whether it is a good c1 or a great c1 will determine if I go with the Asus or Gigabyte GB motherboard. Heck, if it will run over 200fsb with the prometia might as well go with the Asus right????

what si so great about c1? Remember---I am intel n00b

The C1 is the latest stepping and should have more "potential" to overclock higher, but they are still hard to find. They will be more available pretty soon though. If you're hot to get a 2.4 P-4, then get the 2.4B (533 MHz or 133 FSB) which has a 18X multiplier (the same as the 1.8A). However, the bargain would be the 1.8A which if you run at 150 FSB for good bandwidth will give you a 2.7 gig overclock. Not too shaddy.


Go to this link, the first CPU listed is the 2.4 that you listed and the next one is the 2.4B that I mentioned which is the same price.

so i could get the 1.8a rto 2.7? And how much of an overclock can be expected from that 2.4b?

[TheFrag]

wait, the 1.8a's seem to oc just as much as the 2.4b's. Whihc one should I get than? Ae there any other advantages?

PIV's are all basically the same chip, the only difference between them all is the stock fsb and the multiplier. So, for the most part, a 1.8a will end up close to the same overclock speed as a 2.4b. They both have the same multiplier, the 2.4b is at 133 stock and the 1.8a is at 100 stock.

The c1 stepping has done quite well so far. Intel introduced c1 stepping when they pushed past 2.53. All cpu's over 2.53 are a c1. Intel has SLOWLY trickled down the c1 stepping to lower speeds. With a good c1 CPU and good system components, then a 3.2-3.4 ghz speed on air is attainable. With extreme cooling 200mhz fsb on a 18 multiplier chip is within reach. I would not be suprised if phantom punisher put his 2.4b c1 in a phase change cooling setup, that it would be stable at 3.6+. I have my fingers crossed for my 2.4 that is coming in.
