Ok, my dad has an old HP Pavilion 6746C. Product site for it is here:

http://h10025.www1.hp.com/ewfrf/wc/...ocname=bph06042&product=57589&dlc=en&lang=en#

And here's some more info form HP on it.

http://h10061.www1.hp.com/ccsearch/...nder&qry=specifications&Submit.x=0&Submit.y=0

Anyway, the long and short of it is it uses the 370 socket and 810 intel chipset. The stock processer is a 733mhz celeron. This seems to be the same processor:

Anyway, I want to upgrade it as much as I can without buying a new mobo. I'm not sure what mobo it is, the product page doesn't say. I'll open it up later (typing on it now) and post that, but hopefully that won't be necessary.

So, what kind of processors can I strap into this puppy? Does the FSB have to match up? That page from T.H. says 66mhz (I assume thats FSB), but the HP site says the memory is running at "100 MHz synchronous", so that's what I thought the CPU must be running at. I'll try to check the bios (if I can get into it, don't have much experience with OEM computers that have all these fancy locks to keep retards out of the bios and stuff) and verify which one it is.

I was hoping to buy a PIII for it. Somewhere around the 1ghz speed, but obviously as high as possible.

Any ideas?

edit: O yea, here's one option I was looking at:

You're SOL, in this case. The original i810 chipset supports only a permanently fixed 66MHz FSB - but at the same time, the memory runs at a permanently fixed 100MHz. In this case, the memory speed is always asynchronous.

The later i810E supports 100MHz and 133MHz FSB speeds - but the memory speed remains permanently fixed at 100MHz.

Your dad's particular H-P system referenced above can accept only up to a 766MHz Celeron.

:(

Is there anything else you can upgrade? Ram maybe? I have a P3 667 with 128mb ram that ran pretty slow until I dropped in an extra 512mb of ram. I even put in a 64mb GeForce video card I bought off the forums for $10 bucks and an old Sound Blaster sound card I found laying around to replace the onboard stuff. It runs pretty good now.

Urggh... That H-P has no AGP slot at all - only the legacy PCI slot. Thus, video card "upgrades" are limited to PCI (not PCI Express) cards.

Also, that H-P has only two 168-pin DIMM slots, and it's limited to 256MB per stick. Thus, the maximum memory capacity is 512MB total.
 
You can probobly run a Pentium 3 1ghz in there. I'm running a Coppermine Celeron 1.1 in an old HP of mine, it was running a Celeron 666mhz.
 
hmm, maybe i'll try for a mobo upgrade then. Unless someone can confirm acascianelli. It's 3 votes for no and 1 yes, so I'm leaning towards no 1ghz p3 unless someone else can prove the p3 will work.

What kind of a mobo could I get? I have almost 0 experience with intel mobos. Doesn't need to get that good, but it does need to fit in this matx case. I think it's matx, might be super duper matx it looks so small.

what about the ram? Would I have to buy new ram? We've already bought it up to 383mb of ram.

Which exact model HP do you have? HP makes so many different models using a Celeron CPU.

As I said earlier, the motherboard in the thread starter's particular HP has its FSB permanently fixed at 66MHz. Thus, a 1.0GHz Pentium 3 will not work on that particular HP - and even if it does work, it will run only at a sluggish 500MHz.
 
i dont think you can upgrade that cpu to anything better tham what you have in there... like E4g1e said the chipset limits fsb and i doubt the bios has any options to change that

With newer CPUs and newer mobos, you will also need new memory. Modern motherboards no longer use PC100 or PC133 SDRAM memory - but they actually now use DDR400 memory (for AMD and some Intel platforms) or DDR2-533 or DDR2-667 memory (for most current Intel platforms).

well yea, but i'm talking about getting an older mobo that uses SDRAM. You said this mobo does wierd stuff with the locks and such. Does it also use a wierd kind of SDRAM? Or is it just normal SDRAM?
 
anyone? proc and mobo upgrade recommendation? Doesn't have to be better than a 1.0-1.5 mhz P3 or so, but should support SDRAM.

At this point you'll have to buy used. Nobody makes those legacy components any more.
 
How about this:

DFI CM33-TL VIA Socket 370 microATX Motherboard / Integrated Video / Audio / 10/100Mbps Ethernet LAN / USB 1.1 $59.99

and

http://www.pcprogress.com/product.asp?PID=INP3FC-1000EBOEM&m1=pg

PENTIUM III FCPGA(370) 1GHZ 133MHZ BUS 256K $45.00

I don't think I could go up a generation or two and still pay that little.

edit:

Looking at a 478 upgrade.

Celeron D 315 $66.99 (shipped):
http://www.newegg.com/Product/Product.asp?Item=N82E16819112196
2.26ghz

BIOSTAR P4M80-M4 Socket 478 VIA P4M800 MATX $46.98 (shipped):
http://www.newegg.com/Product/Product.asp?Item=N82E16813138262

Course, now I'll need memory. My brother has a dell though, and he wants memory too....

G.Skill (2 x 512MB) DDR 400 Model F1-3200PHU2-1GBNT $75.81 (shipped):
http://www.newegg.com/Product/Product.asp?Item=N82E16820231030
(Timing: 2.5-4-4-8 Voltage: 2.6 ~ 2.75 V)

----------

Hmmm, decisions. That 478 upgrade is looking mighty nice now. I didn't think the mobo would be that cheap. I am seriously considering getting all that and splitting the memory between my brother and my dad. You think every thing else would still work with that biostar mobo?
 
Don't even waste your money upgrading that thing. You are better off buying a new celeron/sempron Emachine for 200 bucks.
