this is an issue that will probably go on till ddr2 takes hold. early on when the pc4000 was a fortune to buy, alot of the fellas discovered their bh5/bh6 sticks would run real well at 5/4 ratio at tight timings, compared to the hi fsb 1-1 with pc4000 that needs loose timings, producing good bandwidth on 875/865 chipsets(especially with 3+v). it did, and still does. now with the advent of cheaper pc4000/4200 (like with komusa's 69.00 pc4200 sticks) guys are saying hey, why spend 175.002x256 to 350.00 2x512 for the rare and expensive bh5 or less rare bh6, when for 140.00 bux or 238.00 i can get some real hi quality 512 or a gig of some very hi 1-1 overclocking ram. especially, since they both produce similar bandwidth.. so basically u dont have to buy real hi 1-1 memory, but it seems that its cheaper and why spend extra if u dont have to..
