Hi people,
I have just the same problem as The Tinkerer. An Abit KR7A-Raid and a 2200+ T-bred (ID 680).
The first time I have mount the CPU, after i have cleared BIOS setting closing the jumper, I get the system works entering the BIOS and when the system restart i have no boot. At that time i have 9N release of BIOS. I found new version B5. I have mount a 1800+ CPU (system works great) and upgrade the BIOS to this release. Nothing! Same result or worse. The system with 2200+ never boot. I have found the post of The Tinkerer and the mods suggested. I tried to connect #5 L3 and i have also no boot.
What i can do? Probably I'll try to retur to 9N release (as the web page says support to 2200+ T-bred), with the #5 L3 closed, and after I'll try to close all L3. But something say to me i have also no boot.
I hope we can find a solution, because this MB is great. With water cooling i get a 1800+ run over 1900 real Mhz. With the same system but with an Asus i can't reach 1800 real Mhz.

Thanks,
Daniele

On another forum, a member reported that the L3#5 bridge trick works with a 2400+ using bios B5. He reported he had the Kr7A Raid board revision 1.0, which is the same as mine. He was able to overclock the FSB to 170 with the 2400+ at 12.5, which is the max multiplier using the L3 #5 bridge trick. That gives a bit over 2100 Mhz speed. I have not yet had the money to buy a 2400 to verify his results, but if you can return your 2200 and get your money back, you might try a 2400, as it would SEEM that the 681 cpus may behave differently in our board. Good luck and report back.

Tinkerer,

Based on what I've read of your experience and others trying the 2200+ in the KR7 (and other boards) I would agree that it's best to stay away from the 2200+.

I have the 2400+ running at 180x12.5 (2.25Ghz) using the L3 #5 bridge trick on my KR7A-R (9N BIOS). I couldn't tell you what version my board is unfortunately though. It's about a year old and I bought it about a month before they switched to the "-133" versions.

I don't think I've seen any reports at all of the 2400+ not working on a KR7A though....

Edit: Looked up my receipt on the KR7A, purchased second week of January this year if that helps any.

I guess whats ironic is I was waiting for a 2400 but got impatient. I recently sent a 2200 back that seemed to burn up in my kr7 board so maybe I can throw them some extra cash and get an upgrade. Of course that Soyo board is on the way too!!!

I would appreciate hearing your results if you do get the 2400. Thanks.

Yes that helps a lot. Appreciate your results. You are the second to now confirm that the 2400 will work and you are using 9N so it looks like 9N or B5 will do the trick. Now if only Abit would make the bios work with the actual multiplier... :toast:
