CPU Upgrade on Proliant DL385 G1

I posted an earlier question on the same subject but for some reason, it doesn't show up when I search on the forum. Here it is again:

I have failed to upgrade the CPUs on a Proliant DL385 G1 with two Opteron 250s to either Opteron 254 or 285. Both result in an unknown or unsupported processor error at POST. The BIOS is up-to-date (A05), and we have tried the various tricks mentioned here on the forum (reset firmware, install CPUs one at a time, and so on).

We've already had the board replaced once due to an unrelated issue, so I do not think this problem is hardware-related.

I am assuming the CPU upgrade options offered by HP do not differ in any way, except for the price tag, from regular OEM or retail AMD processors on the market.

Any suggestions?
