Hi Jdaasoc; Re "I was 100% right on registered DDR DRAM being the preferred adopted standard for DDR. AMD 760MP supports it exclusively; Intel's only DDR standard is registered so far per the pdf link you posted to about 2 weeks ago. Who is left that has not supported it. VIA."
Nope.
In particular, you wrote: "Who is left that has not supported it. VIA." In fact, AMD's 760 supports unbuffered, as does the units from ALi, Nvidia, and SiS. If you total up the DDR chipsets, you will find that there are about 3x as many chipsets that demonstrably support unbuffered DDR than the chipsets you name above, and you don't even know whether the chipsets you named support unbuffered DDR or not.
Neither of us have specs for the AMD 760SMP, nor the Intel i845. I'll bet that when we do get those specs, we will find that the chipsets do, in fact, support unbuffered DDR. The news reports you are reading are very likely in error. What is likely to be the case is that the motherboard versions being offered for sale support only registered, but if the motherboard designer wishes to use unbuffered, he can do so. It's going to depend on the market for the motherboard, and if that market wants big memories, they'll put 4 DIMMs and ask for registered ECCs.
The reason I believe this, is that it is rather trivial to support both memory types, and the unbuffered performance is so much better (with smaller main memories) that no decent electrical engineer would leave that performance on the table. I'm an electrical engineer, you're not. I predict that I'll be right on this.
I'm sure you think you're right about this, but you were oh so wrong about DDR, let's "wait and see" on the registered vs unbuffered, LOL. When the chipset specs get stuck on the internet (and the AMD 760MP spec is likely to get here first, right now I can't get amd.com to come up, otherwise I'd check right now), I'll post a note to you to remind you that you were wrong.
As it now stands, there are still far more unbuffered DDR DIMMs for sale (and undoubtedly being sold) than registered. Almost every DDR machine sold uses unbuffered. The Nvidia chipset is designed for unbuffered. The registered product is going to be a bit of a niche product for servers, just like registered SDRAM. The mainstream memory type is unbuffered. That you would have difficulty perceiving this is incomprehensible to me. And for that matter, why didn't you believe me, an electrical engineer that you damn well know specializes in memory, about DDR vs RDRAM? Instead you believed the crap from Inhell and Scambus. Now you've quit sucking down the Scambus line, but you still believe the crap from Inhell. Just look at Pricewatch and you will see what the next mainstream memory is, you're making this into much too big of an intellectual exercise for yourself.
