DDR Instability Woes Continue

Overclockers.com concludes that using DDR amounts to "Russian Roulette".

overclockers.com

"I think too many motherboard manufacturers downplay this. It looks like a generic issue affecting most, if not all, [DDR] motherboards to varying degrees. Once a board goes over two slots, things can get dicey very quickly.

The pressure on motherboard manufacturers to get product into the market quickly, with eye-popping features ("Supports up to 4 GB RAM!") that are more marketing hype than practical, cheats consumers. For many of our readers, a motherboard costing, on average, $150 is NOT a trivial investment - for this money, we expect everything to work.

If you buy a car that advertises it can go 120 mph, then find out at 65 mph the wheels fall off, I think you would get upset. While a motherboard is not potentially a life-threatening product, the principle is the same: I want stuff to work as advertised! "

Next, we see what happens if you install more than 512MB of DDR memory with an Athlon-- system performance *DROPS* dramatically as the system scales down memory bus speeds and timings to accommodate DDR's inherent instability:

"How could such a souped-up system be so comparatively slow? Memory testing with SiSoft's Sandra reveals that the CyberPower's 1GB memory bandwidth lags behind that of the 512MB-equipped Polywell by about 16 percent. "
