How high a celeron can I go up to?

[Syringer]

On my computer back at school, I'm running a Celeron 1ghz processor at 100mhz fsb..but don't know what chipset my motherboard is using..so what's the highest speed CPU I can run with a 100mhz bus?

The highest of all would be the 1.4A, but we need to know what motherboard and possibly what PCB revision it's using, to answer your question. Can you find out?

It really wouldn't be worth it to pour money into a 400MHz upgrade. Compare the price of the upgrade to a new motherboard\CPU\RAM and see which would be the smarter move.

Its not just 400 MHz. You also go from 128K -> 256K cache, some other improvements.

Do you already have a FCPGA2 version or the older Coppermine core. If your motherboard has a jumper or bios setting to go 133MHz, the FCPGA2 stands a very good chance of 1333MHz at stock voltage and cooling, no extra money needed.

If you have the 1GHz FCPGA Coppermine, a 112MHz fsb setting would be the most you could probably hope for at stock core voltage. Check you bios or motheboard for adjustments or juumpers, and make sure your board can handle a FCPGA2 if you have the Coppermine and intend to upgrade to a Tualatin.

Hey oldfart, got a couple of socket 370 motheboards and decided to play old school overclocking. Ordered a couple of Celeron 1.0a ($35 bucks these days). The sent me a couple of 1.1a and I was disappointed. One of them struggled to hit a 137MHz fsb for 1500MHz, I wanted a minimum of 150MHz fsb to boost the memory (or lack of) bandwidth, so that sucked. However the second one hits 152MHz fsb speeds for 1670MHz at 1.65v!!! Wow, I never thought a Tualatin would hit that high on air-cooling. I put it in my work computer with a 128MB GF3. When it's a little slow I am fraggin' with just as much enjoyment as my home rig. I put a quiet fan on the power supply, and used a speed control to turn the 70mm cpu fan down to 3000rpm. This thing is as quiet as my laptop. The arithmetic and cpu based benchies put it not to far behind my 2.8GHz P4 533MHz laptop. Of course, any benchmarks that need bandwidth are crippled, especially 3DMark2001.

I have brought this up before and am still hopeful. With the awesome power of the Centrino proven, I believe the old P3 Tualatin core would be formidable if it could just be put on a 400-533MHz fsb with DDR. Put a Pentium-S 1.26GHz on a P4 board with some kind of adapter and overclock it to a 166MHz (quad pumped 664MHz) for 1577MHz. With the 512MB of L2 cache it would surely put any P4 under 2.6GHz in it's place.

what's the fastest celeron you'd be able to use on an Abit Bx6 Rev 2 board? i've been thinking about upgrading that one, it's slot1, and i dont think those go all that high, but, i picked up a generic slotket, and running a 600mhz off it now.

I asked this about my BH6 here. The BX6 Rev2 might have better mosfets & caps than my BH6 rev1, but I figure to be safe, 1Ghz is probably the highest.

I'm also hopeful... of a Dothan on a desktop board!!! Think about it, the power of a Pentium III at 2+ GHz with 2MB cache on a 533MHz FSB with dual-channel DDR RAM... I believe it isn't too difficult on the technical side. Don't have to re-work the actual Pentium III chips or anything, just take existing (or upcoming) stuff and make a reference desktop board design for the motherboard manufacturers to play with, then pump a whole bunch of these CPUs into the market.

Heck, if they decide to make special desktop variants that don't need to run low voltage, wonder how high these puppies will run. 3GHz?

Check out this program called inSPECS
it is made by the same people that make the powerleap connectors and apparently tells you the max upgradeable speed, the needed/unneeded connectors you might need to buy to make it work, etc.
the program crashed on my P4 system, but it should work on older system's like yours since it's designed for them.

good luck

Nothing will change the fact that it's still a Celeron

That program shows ya what processor you can use if you use their adapters. for example, they show my compaq 700mhz celeron upgradeable to 1.4 celeron, but, it shows a pic of a celeron with some kind of socket adapter, and they have a 'buy this for $119' button next to it.
The little web program they have does give you great full specs of your system, but, you have to figgure out on your own what you can upgrade to unless you want to save the trouble and click their 'buy now' button.

OH! btw, will it hurt anything trying to put a FC-PGA celeron chip into a PPGA mb? will it fit?
