There are chips out there from companies other then Winbond or Hynix that have been quietly increasing yields while focus in this market have been concentrated on those two companies. Chips from companies like ProMOS and Micron have shown promising performance.
There is no way to expect someone to go out and buy sticks of memory with the latest memory chips on the market and test how they all perform. This is what companies like OCZ, Mushkin, and Corsair are all looking out for on a constant basis. Once one of these companies find large batches of promising chips they stick their high price-tag (and high product support) on these and market them. If your willing to pay the price, generally they offer great performance.
Low-cost memory that does high speeds with good timings is a process sort of like taking out the "middle-man" (high-end "performance" memory companies). But it's unreasonable to expect a brand of chips to remain constant (or similar) in performance and production over a length of time. And it's also unreasonable to expect someone to constantly test out new sticks of chips with new chips.
For someone looking for cheap DDR-480 with decent timings, there usually is only two options, pay more or comprimise. Hynix BT-D43 memory, found on Kingston Value-RAM PC-3200 and low-cost PC-4000, will be able to run at the clock speed, but at what timings?
