Which Celerons @ which FSB to pick??

[AHO]

Seems like no-one have 1.2A@133, and the new Stepping is still a myth no one can solve. I am about to buy a CPU (Tualatin Celeron). I am not looking for the highest clock speed, but rather the best performance.

I know that the FSB and memory has alot to do with it, so I am asking for these benchmarks / opinions, or anything if you have them. All other things being equal and capable (memory and PS Ok), which to choose?

I have an old P2B motherboard, that can only go 100, 112 (or 116?), or 133mhz, (and I think 150 too).

so looking for the best performance from these combos:

1.1A @ 100
1.1A @ 112
1.1A @ 133
1.2A @ 100
1.2A @ 112
1.2A @ 133 (possible??)
1.3A @ 100
1.3A @ 112
1.3A @ 133 (possible??)
1.4A @ 100
1.4A @ 112 (possible??)
1.4A @ 133 (highly doubt it)

Actually if your ram can do cas2 at 150mhz then 1.0a is the best

Unless you can be sure you are gettigna new stepping tualatin, I would advise getting the 1.0A or the 1.1A, as most 1.2's are lucky to even get to 133. Mine is hard pushed to get to 134/135, and I am using some pretty strong cooling.

I have an old P2B motherboard, that can only go 100, 112 (or 116?), or 133mhz, (and I think 150 too).

I've got one of those too, but there were several different models of Asus P2B. Are you sure Tualatin will work in yours? I'm not even sure mine is capable of providing less than 2.0vcore, which is why I never even tried a coppermine in it.

My board is the earliest verison. 1.00. From all the info I gather so far, the earlier P2B boards would not boot below 1.80Vcore. Thus, you have to get a Vcore regulator for it. Some slokets have this, and I plan to go with the Powerleap package.

There used to be a strange BIOS problem with 1.0 and 1.1A with P2B boards where it would not boot. But with the new BIOS (1014beta) things are fixed.

So in short, IT DOES WORK ON YOUR P2B!!!


There is no way I can get up to 150FSB as the motherboard do not have that setting. and I probably need a Chipset cooler at that speed.

So what do you guys think? Another option I found is:

P3 1.2A @ 133FSB (stock).

I wouldn't buy P3 as it is much more expensive and you can get better performance out of the celerons by overclocking.

I would go with 1.1 or 1.2 model at 133FSB if you can find a very new chip. I bought my chip early-August and it was packed and manufactured in mid-July. It even works at 133FSB for sometime but crashes eventually (I tried volts upto 1.8). When testing 133 I was using Alpha PEP66 with Sunon fan.

go for a 1.0A or 1.1A.
having the lower multiplier allows you to bump the fsb much higher, giving a substantial performance boost.

these chips absolutely love more fsb.

i like the 1.1A because with a good one 145-150fsb is possible, this is where the 1.0A starts to falter as well, but it does so at much lower clock speeds

 

[breez]

Remember that he has a P2B and the max FSB is 133MHz.

Thanks for all the comments.

We are now starting to hear about the new stepping actually coming into the hands of some of you. Anyone have benchmarks with the new stepping? I see that one even have 1300 @ 1729 (133 FSB?), thats is VERY impressive.

Just wondering, which will be faster.
1400@ 1638 (117FSB) or
1100 @ 1463 (133FSB)
