Back in the days it was the 1.6A. So what is it now? I am looking to upgrade my 1.6A. I have to EPoX 4G4A+. So what should take a serious look at now? Which one will I get the most overclock out of?

Right this second it is the multi-vid 2.4b and 2.53ghz C1 stepping cpus....MOst of these are hitting the 3.2-3.5ghz range and can have default vcores set at 1.475,1.5,1.525, and 1.55v...obviously nabbing a 1.475 would be better!!!

HOwvere with the 800fsb chips to be realesed like tomorrow from some etailers at 2.4, 2.6, and 2.8 levels and all come with HT I think these may be the new badboys. Ofcourse they will likely need a new mobo like the canterwoods to handle the 200fsb to run them, but rumors and reports have some doing 300fsb+ with 2.4c for 3.6ghz and thanks to canterwood mobos offering 3:2 ratios can keep the memroy in the DCDDR 400mhz range. Can you say 5000's in sandra, HT, 1200fsb, and 3.6+ghz...Oh by the way that is aircooled!!!

Hey Duvie, I remember your name from somewhere. Were you on the huge EPoX 4G4A+ thread a while back?

Well, I went from the 4G4A+, to a TH7II (because I got 1GB of RAMBUS from someone), and now I am back on the 4G4A+. I am still running the 1.6a, but would like to upgrade. I don't think I am going to jump on the Canterwood anytime soon. I've never been one to get the latest and greatest. I would rather spend a few bucks less and settle for 2nd best.

So I guess I'll should be looking at the 2.4b and the 2.53GHz chips. Are the C1s pretty common these days? Or is there a place I should be getting these chips from? Thanks for the help....

I am getting two 2.4c 800FSB w/ HT next week from oversea.
see the link, doing 3.6ghz on air at default voltage.

Can I assume you are getting them from Taiwan? If so, where in Taiwan? And how much for the 2.4Cs? I have a friend who is going back, and I am starting to consider the 2.4Cs. That is a sick overclock....

And sorry if this sounds like a stupid question, but where would I get memory that would even run that fast?

Those p4c will require new mobos and the abit BH7 and I believe even the albatron has an 800 version model...they are all i845pe chipsets and single channel ddr....Only problem is most of those boards will not be much more stable over 210-230fsb so the oc will be pretty small....canterwoods are about the only thing that can offer fsb adjustments high enough and negative mem ratios to deal with those high fsbs....The 2.4 has a 12x multiplier so to get 3.6ghz means 300fsb and that will not happen on anything other then a canterwood mobo at this time...

Canterwoods and Springdales.

Negative mem ratios... interesting....

I think I am going to get a budget P4 for now. I just don't want to spend money on a new CPU and mobo right now. I should be able to get a good overclock with a 2.4b C1 chip, right?

MultiVid C1's from outpost. But once the 2.4C's start to get instock, maybe it (the first impressions look good:).

Multi vid c1's mean they come in multiple vcore options...The chip can come 1.475,1.5,1.525, or 1.55v for default vcode....This I believe is only in OEM chips....

Still 1.6A.

Many 1.6A, mine included, runs happily at 170FSB (2.7GHz). It is 170% overclock.

If you get a 2.4B with a 18 mulitplier. You have a good chance of push it to over 3 GHz, but it is less than 130% overclock.

The overclock for the C series may be even worse percentage wise.

According to this web page, as of March 7th they have been found as OEM (tray) versions only. And from most of the posts from the hardcore overclockers here, outpost.com (2.4, 2.53, look for the Tray Processor description) is still the best place to get one, and still only OEM

And if you read this info from Intel regarding the change it doesn't read like a notice from Intel to retail consumers, but rather a note of change from Intel to it's OEM partners. That's why this is believed to be a OEM specific chip rather than retail.

shoman94...where or who do you know of that is verifiably selling retail multi-vid P4's? To some, that 3 year warranty as opposed to 30 days for an OEM chip makes a difference, but to date I haven't read a single post of someone getting a multi-vid in a retail box. Can you prove your statement to be fact?

HardWired: I could be wrong. But I've seen boxed 2.4B C1's with no voltage written outside the box. When opened they don't have a specific voltage written / engraved on the chip either. So it would suggest a multi-vid?

According to HERE
The sl6rz is available as both......I just received a sl6ef from googlegear which is c1 stepping but not multi-vid. I guess it's a matter of searching for it.

Yes, I see your link, and it does show some as both so I stand corrected. But the multi-vids are the specific one's that are giving some incredible o'cing more so than just being a C1 stepping. I scored a C1 SL6EG from gg and although it was a C1, it wasn't a multi vid and the best I could get without too high of a vcore setting was 2.9ish. This multi-vid I'm running now (SL6S2) is at stock vcore and running great a 3.3GHZ. And with a little bump in vcore, (which I don't want to do) I can get 3.4+ out of it. Quite a difference.

So you're right, if you can find one, the multi-vids are out there in retail box as well, but to get a definite mv 2.4 or 2.53, outpost.com and their tray processor is the place to go still.
