I am wanting to upgrade one my other computers and don't want to rebuild the whole thing. What are my options here?

3 options:

Find a P3 1GHZ Slot 1- cost will be around $100. Compgeeks has them sometimes.

Celery PPGA 1.1Ghz w/128K cache with a Slotket - cost will be around $60

Tualatin Celery up to 1.4Ghz (?) with a Slotket adapter - there is a recent thread on this board about this here:

BX Board Processor Thread

I am not sure how the P3 1Ghz compares to the faster Tualatin celeries, does anyone else?

even the Coppermine celerons were about 90% as fast as a 100 MHz "real" p3, so the Tualatin 1.4 should be at least 25% faster (than a 1 GHz p3).

As I recall the BH6 1.2 has the necessary dividers for running the FSB @ 133MHz so I would go for an adapter and C1.1A or maybe 1.2 (if tB1 stepping). If you do not have PC133 memory or do not want to "reclock" the CPU then a Celeron 1.4 would be a lower performance alternative. There are also Pentium 1.4's but they are overpriced for the small performance increase in multimedia functions from the larger cache.

The Upgradeware adapter can actually be had for $20 (much less than Powerleap).

I found that a C1.1 Tualatin performs about 12% better in 3DMark than a P1.1 Coppermine at default clocks (both 11x100 and 256k). Of course it was also cheaper (even more so now), cooler and overclocks better.

Ok I went out and bought a generic PGA adapter and a Celeron 1.2Ghz Processor. I tried it and didn't work. I think its the adapter I hope it didn't burn out the CPU.

What is a good slot adapter to buy.

The CPU saids
1.2Ghz 100Mhz Bus and 1.5Vs..

Ok thanks I ordered one.. Also I was reading on that other thread that I could use a multiplier even higher than 12 which is what my motherboard has as max is that true?

For example could I use the Celeron 1.4 Ghz or the P3- 1.4Ghz?

Is there a version with a bios on the slocket? My mobo bios doesn't support the 1.4 option

I just read in the other threads that the cpu is locked anyways so you really can't set the multiplier and therefore it may possibly work. Not sure it would be good to know tho.

Quick question, will my heatsink from my celly2 be compatible with a tualatin?

I have 3 tualitans and the only ones I've seen were retails with fans.

You understand you bought the wrong slotkit first time and thats why it didn't work? Voltage for the tualitans is much lower than celeron 2's so need special slotkit.

I ran a celeron 900 at 1200 on a slotkit in my aopen ax6bc for my last processor, great performance boost. My mb had the 1/4 pci though.

yea, either slocket T, or if you already have a fcpga slocket, you can attempt the mod at overclockers.com i did that cuz slocket t wasn't out yet when i needed. plus i'm cheap. it worked:)

celly retail heatsinks aren't bad. oc is easy. things don't run hot in the first place though. for apollo pro boards its easy to hit 133mhz so 1.1a @1.5 was what i did.. 3 times:) bx might be harder. if you know your memory/pci/agp can't go all that high, get a 1.4ghz celly or something.

Are there any other places then stratton computer that sells those slot-t adapters, i hate it when some store uses ups to ship to canada.

Often they wont. The Tually has an IHS and requires a HS with a much bigger contact area than a non IHS S370 CPU. Some have a big enough contact area, some don't.

As far as BX chips making it to 133 FSB, most do it very easily. The couple of exceptions are Abit BH6 rev 1.0x and BX6 R1 boards that dont have a 1/4 PCI. On any of them you need a video card that is ok with an 89 MHz PCI bus.

You got me worried there for a second, but it turns out i have an alpha pep66t heatsink, after looking at the tualatin core (center) it looks like it'll be a perfect fit, assuming the copper area represents the size of the cpu.
Does anyone maybe have the same heatsink/cpu and can comment on the fit?

well, from what i remember about my celeron 533 compared to the tually 1.1a.. they looked about the same really cept for the heat spreader. the tually even ran with an old crusty golden orb 1.0 for a while:) i guess there might be some totally weird heatsinks out there without even an square inch of contact area.

Intel factory FC-PGA heatsinks will not cover the the IHS on a Tually CPU. Aftermarket HS have a better chance of doing so. I dont think a GORB (not that I would ever use one) would with that round base.

not that it matters, retail package cellies cost maybe 5 bux more then bare. the retail heatsink isn't bad either. 70mm fan on my last one.

Close... nope, but with shipping its still cheaper then from the US
It cost me $8 CAD for expedited shipping (Canada Post) from Kingston to Toronto.

Their online ordering system is wonky, and put my billing address instead of my shipping address. However, I complained at 10 pm and they corrected it at 11:30 pm. :Q

It arrived in just a couple of days and it was packed well. I haven't tested it yet.

By the way, I have the PEP66 (non-t) as well, but I'm just going to use the retail heatsink on my Celeron 1.4. The PEP66 blocks one of my memory slots (Asus P2B).

Looks like you can haggle with bytewize a little bit, the 1.4ghz celeron was $95 in other stores but $115 in their store.
So the sales guy dropped the price to 99 bucks, so ill save a bit by not paying shipping from two stores :)

Posting from a 1.4 GHz CPU on BX. :) With Upgradeware Slot-T.

Celeron $95 locally, and Slot-T mail order from bytewize.

Now go update that system rig. :)
