Right now on the AMD side, as previously, we have ECC support for DRAM. ECC capable DRAM on the desktop had become nearly extinct as the wast majority of desktop CPUs were Intel and didn't support ECC at all, in any shape manner or form.

Now that the "hot" (not thermally speaking) CPUs are from AMD and they do in fact support ECC, I have the distinct feeling from my wanderings on the Web that desktop ECC offerings are on the rise although I suspect that Crucial/Micron have at the same time been cutting back on their unbuffered ECC selection. Strange times indeed.

I freely admit that I have not made a rigorous study of this market area recently. My excuse is that I'm tired and weary from years and decades of fruitless searching.

I'm fervently hoping that we can see a resurgence in ECC offerings, where, as in the past you would be able to buy Parity/ECC memory at every market point at a 5-20% price premium.

Please correct me if I'm wrong.
