S-A 333MHz

[Pendragon]

I have an ageing PC that needs a CPU upgrade.

It currently has a XP2500 Barton, The Ram is running at 333MHz. As the Ram is 333MHz not the faster 400MHz. The question is what is the fastest Chip that can be fitted?

asrock amd support list

K7S41GX seems to be the motherboard number... if that number is from the motherboard...?

[Pendragon]

That will teach me to post from work...

MoBo is a cheapie Matsonic (No I had never heard of them) MS8147C with VIA KT400/A Chipset Socket 462

Jumper options for FSB are 100MHz, 133MHz & 166MHz

I have a had a look at the BIOS, Things I can change... RAM FSB 133MHz, 166MHz (current) & 200MHz with the option to "Bank Interleave" (Disabled) sorry I don't know what this means...

CPU FSB variable from 166 to 199 MHz

Your processor settings are 166. you could use a XP 3200+ 333MHz ,2.2GHz 512kB Socket , even though the board will take 200mhz sdram.

How about the 400MHz Socket A CPU's because I can adjust the CPU up to 199MHz??

Highly unlikely the board will run at that
You may have settings that will show 199X2 but that motherboard will not achieve that.

MS8147C / MS8147CR
* Question:
What is the fastest processor that MS8147C/MS8147CR can support reliably?
Answer:
AMD Barton 0.13u 333MHz Athlon XP 2500+ ~ 3000+
AMD Thoroughbred ( A/B ) 0.13u 266/333MHz Athlon XP 1700+ ~ 2600+
AMD Thunderbird , 0.18u , 200/266MHz, Athlon 650 MHz ~ 1400 MHz
AMD Palomino , 0.18u , 266MHz, Athlon XP 1500+ ~ XP 2100+
Duron : 650MHz ~ 1300MHz

Thanks guys, Just have to find one of those 3000XP's may end up on ebay getting somthing second hand Grrrrr...


But again thanks for the help

[slavedriver]

While upgrading your CPU be advised the 3000+ @ 3200+ comes both in 333FSB and 400 FSB you want the 333FSB.

Just a case of finding one...

Try turning on your interleave options if it'll stay stable (interleaving is a way of making multiple memory banks appear to be one resource to your system & letting them all get used all at once instead of independently, maybe 10% performance boost here on its own without spending any cash whatsoever )

& I'd question how much 'real' performance gain is to be had from moving from an xp2500 chip to an xp3200 .. 700 'virtual' Mhz ain't so much ! - waste of money imho .. maxing out memory will produce more gain performance wise, as would raiding the current system, or even just adding a second disk for your swap file might make as much difference .. (all bits which are 'adding to' your system & not just replacing & chucking 'nearly the same' in the bin!)
