I'm running up a kr7a, it's about a week old. Specs:
kr7a-133
tbird 1.4 (factory unlocked)
256 stick samsung -ctl, known stable to 208 at 2.5-2-6-2-1T, DCLK Feedback Delay 0 ps in another kr7a.
GF2 GTS
New CMOS battery, new tight CMOS jumper.
When new, it "felt" nice and seemed to behave well. Running it up, though, at 190 FSB my InHel Pro100+ NIC died. The system lost the nice feel at the same time.
Installed a D-Link NIC and over the next 5 days COAXED it up to 203 at 7.5 mult and stock volts. Toast runs over 24 hours, NP. Sandra mem bandwidth benches for over 24 hours, NP. Memburn the same. Prime95 gets rounding errors and aborts at any speed above 192 FSB.
Now, get this:
Running at 200 FSB, if I set the multiplier to 7 it will not boot. CMOS reset time. Further tests show that setting the mult to ANY setting other than 7.5 requires a CMOS reset and then the system won't post above 185 FSB.
If I change the FSB by a large amount, like from 200 to 133 or 200 to 166 (so I can ghost the partition, for example), it won't post. CMOS reset time again. The same problem happens when I CMOS reset - any large FSB jump and it won't boot. I have to work it up like 133->166->180->190->200+
At 206 finally, memory 2.5-2-6-2-1t, 4-way and 4 queue depth, again it's stable - BUT Sandra bandwidth is only 3040. Setting 6A:FF in WPCREDIT gets it to 3056. Should be over 3100, right?
Abit's site is unavailable to me else I'd already have an RMA number, but I thought - why not throw the problem out to the experts :) TIA for any suggestions...
