Hi guys,

1st, apologies if his is posed in the wrong section,

I'll try and give as much info as possible, but as you'll soon realise im a bit of a novice!

Anyways, I have just replaced my amd athlon 2400+ with a amd sempron 3000(barton core i believe if it makes a difference)

now i believe the 2400 had a fsb of 266 (133 in bios) however the 3000 has a fsb of 333. however the option in the bios to change from 133 to 166(333) is greyed out. any ideas?

My motherboard is a Time K7M-400 Motherboard which i believe has a VIA chipset?

BIOS: Phoenix Technologies, LTD 6.00 PG 07/08/2003

memory = 512MBDDR PC3500 256MBDDR PC2100

Windows XP Home Edition Service Pack 2

because i cannot change the fsb the processor is only running at 1.6ghz


any ideas guys?


thanks

Jim

I wonder if your mobo has a max FSB of 266 and can't do 333. I have a PC that has an old mobo with an Athlon xp 2600+ that has a fsb of 266 and can't take anything higher. If it can't you will be stuck at what your CPU multiplier is x the FSB speed., thus resulting in a lower than normal CPU speed.

This is just a shot in the dark, though.

I don't know if this will make any difference, but try removing that odd stick of pc2100 ram. You are using two completely different types of ram, and now a new CPU with a different FSB... it could be messing with it.

Otherwise, have you tried updating your bios?

have taken the stick out, didnt really want to flash the bios, but if its the only option may have to, can this be done without a 3.5 floppy?

Well, don't jump the gun on that. I don't know if that will really make any difference. But, the reason I asked that is that sempron is a much newer processor than the 2400 you had in there. It is possible with a new bios, that the CPU would be correctly identified. On the other hand, flashing the bios could lead to other problems... I never do it, unless it is needed.

But yes, you should be able to flash with a 3.5 drive. The exact procedure is a little different with every board though.
