Ancient, FIRST generation Corsair PC3200: i865/400MHzx2 compatable?

Do you suspect at the most relaxed latencies that the first generation, CL2.5 Corsair PC3200 will work in dual-channel mode at 400MHz? I have two 512MB sticks of this stuff.

I have two 512MB sticks of the first-generation XMS3200c2 that run perfect (i.e. - pass memtest86 for 24hrs) at 2-3-3-6 on my Intel875PBZ board. They actually run better on this board then they do in their actual home, a P4B533-E running at 150FSB. On that board the best they'll do at DDR400 is 2.5-3-3-7! Go figure.....

I'll bet yours will work just fine too.
