Couple Abit IS7 issues...

[MDE]

Pentium 4 3.2C (30 cap) w\ Zalman CNPS7000A (52C full load)
Abit IS7 (latest BIOS)
1GB (2x512) HyperX PC4000
BFG GeForceFX 5900XT

I picked up an IS7 to replace the ECS board from a Fry's combo that I picked up and I'm running into a couple of snags.

1) I can't get over 220FSB at all, which coincidentally is what the ECS board maxed out at. I've tried upping the VDIMM to 2.8V and the VCORE to 1.600V which didn't help.
2) Even enabling "Turbo" mode in the GAT settings makes the system either completely unstable or it just won't boot. I've seen Auto-Auto-Auto-Disabled-Disabled as recommended settings, anyone have theirs differently?
3) Sandra reports my memory bandwidth at ~4000MB\s, which is ~60% efficiency, something's wrong but I can't figure out what.

I had the same problems with an IS7 board, i turned out to be the HyperX PC4000. I swapped it out for some plain old Kingmax PC3500 and all my problems went away. Better memory benchmarks and higher OC.

On the same note, i just noticed that the heatspreaders on mine are different colors (one was more purple, the other was blue) and labels, one stick has Samsung chips, the other Hynix. Took one stick out and it booted right up at 3.6GHz.
