UPDATE as promised -----> results of my work today
1) First I flashed my A7V with latest BIOS Ver 1011, and reset BIOS defaults
as suggested in AFASH's README.TXT
2) Installed the new 1333/266 Athlon
3) Set Jumper Free to [off ], so I could control FSB and Multiplier with
dip-switches.
4) New BIOS faithfully reports correct CPU speed.
5) Now------->I'm having difficulty Booting......BIOS goes to FAIL SAFE
(BIOS SETUP) about 1 of 5 boots...Red text BIOS SETUP Message indicates
that CPU or Memory is having problem with settings and falls back to 100MHz
Memory and 33MHz PCI. I progressively backed speed down to FSB=100MHz
and Multiplier of 10 for 1,000MHZ CPU which is where I started (the old
CPU's speed), BIOS still goes to FAIL SAFE just as frequently as when I has
it set to my initial target speed 107 x 12.5 = 1,391Mhz. As I am typing
this, I am at my desired target speed 107 x 12.5 = 1,391Mhz and all is
fine, I have many browser sessions open and lots of application open on my
desktop....Rock solid if I get past the BIOS FAIL SAFE.
6) Next I will remove one 256MB memory stick at a time to make sure it is
not memory related, I added another 256MBs, which could be the problem.
7) Then I will put the old Athlon 1000 back, just to check.
8) I'll remove all PCI cards (except AGP) to take load off the power supply.
9) I'm out of ideas if the old Athlon and both memory strips work without
the FAIL SAFE problem.
10) I could always hit the reset button when I get a BIOS SAIL SAFE halt.
As I indicated, the system seem solid at 1.391Mhz. I'll keep it at this
high speed to see how it performs over time.
11) I also checked the voltages using BIOS SetUp......and found
Vcore=1.78volts, +3.3= 3.49volts, and +5 = 4.00volts .....the VCore is still
set to the [CPU default]. Should I jack with the Vcore voltage??????
12) Anybody got any ideas?????
Thanks, Joe101

For those following this thread...........My Athlon 1333/266 I ordered from
www.spartantech.com ($40) just arrived and it is UNLOCKED or at least the 4
jumpers at L1 are clearly closed. This weekend I will try to run at
105FSBx12.5=1312MHz on my A7V. I will post results here at a future date.
