FSB Problem

Call me Stupid if you want, BUT my beleif was that 1ghz Athlons and above the FSB is 133mhz, well I've got a 1ghz socket A but it'll only run at 100 fsb 33 pci clk???? :( here's my spec

mini tower 300 watt psu
1ghz athlon Socket A
256 mb 133 sdram
Abit kt7 mobo (With latest 4in1 update)
16mb stb velocity 4400(using Det3 drivers for win2k)
creative sound card
seagate 20gb hard disk
ambient 56k intel ham modem (yes they Suck)
40x cdrom

four fans in the usual places

the thing is i've o/c'd it to 1.1 @ 100 fsb works fine, doesn't bat an eyelid, but as soon as I run it at 1ghz at 133 fsb, it's jumper one time....

so any advise would be great.

Thanx in advance

All new mobos run off of a 100Mhz or 133Mhz bus. The difference from the old is that AMDs are double pumped. That's where they get the 200/266MHz mobos. Intel only uses the 100MHz bus to get the 400Mhz.

With that information, you must have the 200MHz bus. <a href="http://www.abit-usa.com/eng/product/mb/kt7.htm" target="_blank">http://www.abit-usa.com/eng/product/mb/kt7.htm</a>

made a mistake, got an abit kt7a, it's been one of those days, have been reading the other postings, and got afew idea's ie removing my two pci cards to see if that make any difference.
