I just ordered up 2GB of OCZ Reaper PC2-9200 memory for my P5B. At $35 CDN after rebates it was hard to say no.

The board seems a little memory fussy with the E0 and bios 12.36. I have 2x512MB of old generic DDR2-667 CL5 with Micron D9 chips that run reliably at DDR2-900 CL4 on this board but my Ballistix 2x1GB runs fine for days at the same speed but then won't boot up and I'll have to play around with bios settings and play musical memory to get it to boot up again. If it doesn't like the Reapers then maybe it's time to retire the P5B or wait for another bios to try.

I'm just hoping to have as much fun as this guy did with his P5B:
