<<The salesman told me that the Micron systems (Athlon DDR and Duron) were selling like hotcakes.>> Yeah, all 1 of 'em, I know. Get a gander of this uberclocker's report: gamepc.com "....Rambus DRAM....is a fantastic memory technology when used in the right situation. Clearly, the Intel 820 and 840 Pentium III chipsets were not the right choice to introduce RDRAM with, as the 100/133 MHz FSB of the processors didn't utilize the full potential of RDRAM. The Pentium 4's "Netburst" (Yes, I know, clever name indeed) 400-MHz FSB finally validates what I've been saying all along.....Overclocking RDRAM isn't that much different than SDRAM....So how do you tweak your RDRAM? First off, just like with P3's and Athlons, when you overclock your front side bus, that also in turn overclocks your memory, since by default they are synchronous. For example, if you're running at 460 MHz FSB, your RDRAM will be running at 460 MHz FSB. If you feel so inclined, with the P4T motherboard you can change the memory bus to asynchronous, and pull it down to PC-600 speed using the RDRAM multipliers. So if your FSB is too fast for your RDRAM to handle, you can pull it down with the multiplier to a more reliable speed. In this situation, if your FSB was running at 460 MHz, your RDRAM would be running at 345 MHz. Just like SDRAM, some chips will run at higher frequencies than others. Unfortunately, since there are so few companies with RIMM's available on the market today, it's tough to get a clear picture which sticks run at higher frequencies than others. Fortunately, every pair of sticks we've tried happily run at 460 MHz at least, while some went up to 480 MHz. This effectively brings the memory bandwidth of the RDRAM up to 3.68 GB/s and 3.84 GB/s. Compare this with standard PC-133 SDRAM (1.06 GB/s), and even PC-2100 DDR SDRAM (2.1 GB/s), and you'll see a pretty large gap...." Here's the best part: the Nvidia DDR card can't keep up! "P4 1.5 GHz - High Quality - 1600x1200x32 (Higher Scores are Better) Again, not much performance gain when dealing with an overclocked processor, due to the GF2 Ultra being the bottleneck. At 1024x768 and 1600x1200, the tests are almost completely limited to the video bottleneck. In Fastest mode, the system gains the most performance, which is only around 11%. Only 11% performance gain with an 18% overclocked processor. C'mon Nvidia, give us NV20, so we'll stop bitching about the video bottleneck! DDR is dead (=niche only). Long live the king, RDRAM. BP
