Have I been sold the wrong processor, “1800xp model 8 Thoroughbred” running on an “ECS K7S5A ver 3.1 bios date 08/09/2002 s.

Three times since acquiring about 2 weeks ago, on start-up computer has reverted to original set-up of 1150 MHz, even date and time has reverted to 08/09/2002, giving messages “CMOS SETTING WRONG” & “CMOS MEMORY SIZE WRONG” requiring me to press F1 and run set-up.

computer shop that sold these to me is sure that the K7S5a will run with the “1800xp model 8 Thoroughbred” CPU.

AMD states ECS K7S5a is a recommended motherboards for “1800xp model 6”, ECS K7S5a is not on recommended list for “1800xp model 8”
ECS site just states Athlonxp will run on ECS K7S5a

Try clearing the CMOS then go back into bios and change any settings you need to.
Just make sure cpu is set at 133

will check that out, don't fancy updating bios though.

emailed AMD & ECS to verify if model 8 has been tested with my mobo, no response from AMD yet, ECS answered with "change cmos battery" ???

already changed battery, not that.

click here same problem, try the advice given there. They also say replace the battery.

this machine boots and run ok most of the time, but 3 times now, from cold it has come up with this prob, have changed battery, original one was tested and ok, so not battery.

looks like bios update needed.

a bios update really isnt really needed since all you need to do is change the FBS settings to 133/133 and it should work! i have the same mobo with an 1700xp and when i first booted up the first time, my cpu was only recognised as 1100 mhz but after i changed the fbs, it went to the full 1700!

under normal circumstances fsb settings are 133/133, three times now it has reset itself to as new, 100/100 1150 MHz original date of 08/09/02 etc, won't boot and requires me to press F1 and reset bios, then ok for several bootups, no set pattern for this problem.
