OT -- overclocking Micheal Potter --
you saved me!
"I think that you can get a small speed
boost by running it at a 75 mhz bus. However, your PCI slots will
then run at higher than spec."
About an hour after I read this, it sank in, the part about the
PCI bus running faster. THEN LIGHTNING STRUCK! At 100 Mhtz
board clock, the PCI bus MUST run at 66Mhtz., otherwise
An Abit BH6 running a P2 would be out of spec. for all PCI
cards I.E.
board PCI Celeron 300a
66Mhtz 66Mhtz 300Mhtz core (66Mhtz I/O)
75Mhtz 75Mhtz 338Mhtz
83Mhtz 83Mhtz 375Mhtz -- disk falures here
100Mhtz 66Mhtz!!! 450Mhtz
103Mhtz 68Mhtz 463Mhtz
This was a bad design choice. If I had designed the board,
the table would have looked like this:
board PCI Celeron 300a
66Mhtz 66Mhtz 300Mhtz
75Mhtz 75Mhtz (best disk perf here) 338Mhtz
83Mhtz (83*2/3)= 55Mhtz 375Mhtz
100Mhtz 66Mhtz -- ie (100*2/3) 450Mhtz
103Mhtz 68Mhtz -- ie (103*2/3) 463Mhtz
I have 3 Cel 300a's, none of which I could get to run at
83Mhtz.
BINGO. THEY ALL RUN AT 100MHTZ. The failure @ 83 was on
the WinBench99 DISK ACCESS TESTS. The PCI bus was
failing @ 83Mhtz., not the Celeron @ 375!!!!!
I'm doing a serious Floating point fault test right now to
see if any of the Celerons run fault free at 450.
At any rate, I got the kick-*ss gaming system I was looking
for. Even better if it is truly rock solid for all
applications.
WooWee,
Joe
BTW Cel300a @ 450! IBM Deskstar 7200! IDE-:( Banshee!
Maybe I'll get a V3. Yahoo!
BTW I just saw P2 350/100 for $179
P2 400/100 for $258 |
