My desktop system, which is listed below, has just been upgraded to a newer cpu. I'm running an athlon 1.33 and was tweakin around with it and ran into the same wall I did with my old 950 tbird. I cannot, for the life of me, get the fsb to go over 140 stable. That equates to a 7 mhz fsb oc, pretty weak in my book. Does anyone have any suggestions with this board? Ive tried loosening the ram settings, upping the dimm voltage etc to no avail. The nice thing is that this cpu came with the mult unlocked already (although the pencil trick woulda worked fine, its nice to have it come that way ;) ) Any kt7a gurus out there that can hook me up??

Remove all other periplerals and re-test the max FSB to ensure you don't have a sound card or other device that doesn't deal with out of spec PCI speeds.

If this doesn't get you an more the other option is to pencil trick the Tbird and UP the multiplier to 11 or so.

Got any codes off this Tbird? You may not have a great chip.

The stepping is AYHJA. Ill try to eliminate the pci possibiliteis. I'm wondering if anyone here has had any experience with this board and what it is capable of doing. It was a pretty popular board at the time so I'm sure a few of you out there who have been doing this for awhile have had it. I would appreciate any further input.

I used to have a KT7a. I got my AXIA up to 1.47Ghz on it. The AYHJA should be good to go that High.

Got the latest BIOS on it?

Yeah i can get the proc close to 1.6 using multiplier adjustments but at 1.6 I get some freaky errors hehe. I was tryin to get as much as I could outta the fsb but still no luck over 140. I wish that i could lock the pci and agp buses on this thing but eh thats why we upgrade lol

well, my AXIA did POST at 1.6Ghz on air, but that was it. It really is the limit for Thunderbirds on Air cooling. In fact, on any cooling AFAIK.

The 140 thing is likely the KT7a chipset holding u back, nothing else. The 'a' descriptor was for the 'jump' from supporting a 100mhz bus to 133Mhz.

The KT7 could only do about 7Mhz over stock too, at around 107Mhz bus when it crapped out.
