Questions about DDR RAM

price-differential (in favor of Beta, BTW), they both had similar prerecorded movies out, and the prices of the machines were almost identical, what made VHS "win the war" was the fact that Sony thought it owned the market; and saw no reason to upgrade or add features to their machines. The competition did. [...] Pure idiocy (in my opinion anyway) on the part of Sony management. It's not clear that they HAD similar prerecorded movies: one "fact" (no idea if it's correct, or an urban legend) about beta which is often repeated: Early on, Sony didn't permit porn being distributed on Beta (although it clearly either did later, or couldn't stop it - I've a porn tapes on Beta that I picked up on clearance well into the 90s, and saw a few on the shelves in Mexico in the late 80s where rental tapes in general - not specific to porn - were easier to find on Beta.) -- Nate Edel http://www.cubiclehermit.com/ preferred email | "With all the accumulated wit and wisdom in the is "nate" at the | world, it is pointless to try to select a few posting domain | choice quotes."

Kinda a tail-chasing argument there. It costs 30-50% more because... It certainly wouldn't cost the manufacturers 30-50% more. Yes, the argument is somewhat circular. But matches data. No, in full quantity, it'll cost 12.5% of DRAM. Why do you doubt their design choice to omit ECC? It's not a design choice. It's a marketing choice. Semantics. They choose the design they will market. I cannot distinguish between a design choice and a marketing choice unless marketing is pushing vaporware. ECC came about because the word size got big enough that ECC cost nothing over simple parity. Both were dropped because memory was a significant fraction of the cost of the system. .... and was not perceived as offerring commensurate benefits. A hard disk is a bigger fraction of system cost. A floppy perhaps somewhat smaller. Both were retained for perceived benefits. I agree with you here. ECC isn't going to fix M$'s crap. I doubt anything will Again, you presume you know better than Intel, AMD, Dell, HP, etc. Than their marketeers? About technical issues? Well, yes... But ECC isn't a technical issue. Including it or leaving it off does not fundamentally change the system. It is an option to improve reliability. The real question is: How much? If it is a lot, it will be included. If it is not, it will be omitted for cost savings. Again I ask: What BER data do you have to justify ECC? Here you are wrong, unless you consider medical equipment (defibrillators, life-signs monitors, and such) "non-life critical". I couldn't count high enough to track all the PC-based hardware and Windows crap when I was in the hospital, earlier this year. No, being there, seeing that, didn't give me the warm fuzzies. I deal with industrial controllers. I haven't seen these in hospital, but they'd scare me too! -- Robert |

If you can identify the motherboard used on your system, perhaps we can save you the trouble of returning those ECC dimms before you buy them. If the chipset - or the motherboard implementation thereof - doesn't explicitly support ECC dimms, you're gonna be SOL... Not to mention that few mobos support both 168 pin PC100 and 184 pin DDR PC2100. -- Robert |
