Yes, we did that too, and it works fine -- in the P/E-P55T2P4D boards. However, at about $2000 per 64MB SIMM module, this is an expensive solution. And, as noted, those same SIMM modules in the P/I-P55T2P4 boards would not work at all until we relaxed the timing to 70ns. It ended up being cheaper to buy more machines each with 192MB of 32MB "cheap" EDO RAM (64MB x 4 SIMMs = $8000, 1 extra MB + 12 x 32MB SIMM's = $4000, and you end up with more memory on average too) ...
