Whats the fastest CPU/MEM my ECS K7S5A can use?

[ShawnReeves]

Looking to upgrade my CPU and Mem on my K7S5A. Currently running a Athlon Tbird 1.333 and 512mb PC133.
Not looking to jump to another board.

Thanks,
Shawn

It depends.

Try the newest BIOS.

Do you know what board rev you have?

The board should support an XP2600+.

I have run PC2700 cas2 on K7S5A.

DDR is the only way to go.

I think its rev 1.0 (non-pro)
Bios is up to date also.

Watch what you buy - the XP2600+ comes in 133 and 166 MHz bus flavors, you need the former. Also, no 2500+ since this also is 166 MHz bus.

On the RAM front, you need at least PC2100 ("DDR266"); CL2 operation at 133 MHz should be supported for best performance. Faster RAM will also work but the extra headroom won't get used.

I have the exact same question, except I flashed the cheapoman bios a while ago with good results, also gives a lot more options on the CPU/PnP page. If the bios has a 166 setting, will that work with the Barton 2500+ (still using PC2100 RAM)???

Just for the record, I just implanted a 2400+ into quite an old K7S5A system (bought Dec 2001, originally with an Athlon-1000/133).

I put a new fan/heatsink on (an Arctic Cooling Copper Silent), and that was it. BIOS detected the CPU change and reverted bus speeds to 100/100; set back to 133/133 and all is fine.
This system is running on SDR RAM btw.
