KR7A: What will happen if I use an older BIOS with a TBred B?

    Here's the deal: I had a very early 1600+ Palomino in my KR7A-RAID and
    it ran hot. I was using BIOS 6N, and the system had always been very
    stable for me, but I figured that since 1700+ TBred's were only $42
    shipped I might as well grab one. Newegg sent me the best one: JUIHB
    DLT3C! I flashed to BIOS CX a few days before it arrived in order to
    gain TBred support. The new chip indeed lowered temps (34-38C!).
    Everything seemed fine...but I found out there are thousands of errors
    in memtest86 (see specs at bottom; it's not the RAM).

    I tried some Corsair 2x256mb TWINX2700LLPT, which works fine in my
    nForce 2 systems, but it made the KR7A unstable EVEN at 5x100mhz (yes,
    a JUIHB at 500mhz) and 2.5-3-3-6-2T and bank interleave disabled (it
    was much more stable at 100mhz, but still not entirely)...this RAM
    runs perfectly at 2-2-2-4 in my nForce 2 at 133mhz, and 2-2-2-5 at
    166mhz! I tried each stick by itself with no luck. Yet the TWINX is
    running flawlessly in an MSI K7N2G-L at 2-2-2-4 with a 1700+ TBred A
    this moment. I had to put the KR7A's old RAM back in: Corsair 256mb
    XMS2700C2. It works well enough, but the erorrs in test 5 of
    memtest86 are still there. The system is stable enough to be used,
    but will crash in games after a few hours. With BIOS 6N and the
    1600+, it seemed infinitely stable.

    Here's the deal. I did a search on this news group and found that I'm
    not alone -- many people are getting these instabilities and errors in
    memtest86 test #5. The system seems like it became less stable after
    I flashed it from 6N to CX. So, maybe if I return to 6N, it will be
    stable and I can use the TWINX 512mb memory instead of the XMS 256mb

    BIOS 6N was released before the TBreds came out, and thus is not
    listed for TBred support. What will happen if I flash back to BIOS 6N
    and still use this 1700+ TBred B? I don't have the 1600+ Palomino
    anymore, so if the TBred won't work with BIOS 6N, I'm gonna have

    It should work ok, it just wont recognise the cpu at POST.
