s478 Celeron 400MHz fsb

[go_for]

I have an old Abit BL7 that could use a fast CPU. I see the celerons in 2.4-2.8GHz range come cheap on fleabay, any idea on which are the best overclockers ?
The P4s are almost triple in price and not sure whether its worth. This board supports only 400MHz fsb CPUs(but has fsb range upto 250MHz, PCI lock and vcore adj.)

one example target: 2.4GHz northwood celly at 24x133MHz = 3.2GHz

Well, if it supports 250, you might want to try finding a Celeron D with a Prescott core. Those use 533MHz, but if you can get it to boot (lots of maybes, I know), you can up the fsb to 250 and get just a tad less than it can do. Those are also cheap, and there are CPUs made for 478 out there. And the extra cache makes it even better

Try googling around to see if it would work...

For good OC's, I think the Northwood cores (pretty sure that's the name) clocked well. But they ran pretty hot.

If you can swing a Pentium, get one. P4 cellys are dogs even OC'd with only 128 to 256 L2 and 16+16 L1. I know this don't help but here are some US prices for them: http://www.geeks.com/products.asp?cat=CPU

I agree with SA, but get the Socket 775 Cedar Mill rather than a Presoctt or Northwood core. Mine have gone to 5.0+Ghz and that is indeed a kick.

For a sleeper, look for a 775 Celeron D with a Cedar Mill core or architecture or whatever.

Know that will entail a new mobo, but the old pre core2 intel parts are dirt cheap here.

My 775 P4 off ebay was just over $40 with shipping. Some of those processors can also run on the newer P35 motherboards. Often those can be had new for less than a used socket 478 version.

Sorry I am not ready to go :ntel way again for while . I just want to max out this board as I have all other necessary components available.
afaik, a prescott will not work on this i845 board. A cel 2.4/400 goes maybe for some 10-15 Euro.

Fairly good results in this old article

I did find one P4 2.8GHz/400, but lets see how its price develops. But yea, a P4 2.4GHz maybe, applied with some successful OC sure is better than a celly.
Any experience how well the P4/400s respond to 133MHz FSB ?

I've got someone with a similar problem.
His mother uses an old dell, and it's a slow mofo. A faster CPU 'd be nice (Celeron, 478, unkown speed). But I think the best thing for it would be a reformat. I would have done this already, but his mom is stubborn. So it could require some convincing.

Give her a new or preowned harddrive, install OS, transfer necessary backup files to that new drive. Keep the original as is, stored away somewhere for backup in case the new one fails.

ok, my bid on the P4 2800 Northwood took. Received it today and tested it on a cardboard build. I had a bid on celeron 2.4, which then went to someone for 10Eur. For this one I had to cough up 27Eur, oh well, its a rare CPU, not many 2800/400 P4s around.

Well since Win7 ran so well on the 8RDA, felt tempted to see what Win7 does to this old horse, abit BL7 + P4 2.8GHz.
Set it up as in my sig, and fired away. Stable it is, although a bit on the hot side.
Submitted my 1st P4 benchmark here. Can say the 8RDA is way snappier, but not too bad this one either.

Too bad the trial period for W7 will be up before
we know it!

[go_for]

yes, too bad. I still remember the Vista early days, same circus, then at the end nothing...

A 2.4 celly will run, but it's a long drop from a equivalent Northwood.
