<<WRONG AGAIN JACKASS>>
"I was 100% right on registered DDR DRAM being the preferred adopted standard for DDR."

Xbitlabs.com was describing a dual processor board
which, judging from loads of RAIDs, 64-bit PCI, etc,
was intended for SERVER MARKET. In server markets,
it is mandatory to offer Registered Memory with ECC,
no matter SDRAM or DDR. Therefore your example does not
support well you narrow conclusion.

The 760MP is targeted at the large memory server market, so it's not shocking that it's designed primarily or exclusively for registered DIMMs. No doubt ServerWorks's will be the same.

Not that it matters a great deal, but why do you insist that registered DIMMs are "the standard", when ALL of the high-volume SDRAM and DDR chipsets/systems use unbuffered?

Hi Jdaasoc; Okay, the AMD-762 is for registered memory only. (I know this from looking at the data sheet, not from the useless marketing PR you linked to.)

Now reply to the rest of my post. Registered memory is for server chipsets, not for mainstream desktop machines.

Here's a list of chipsets that support DDR, according to chare's famous chipset list. Some of the chips labeled as "unbuffered only" probably support registered as well, and perhaps some of them support registered only. But I'm not going to go find out the details for 40 chipsets for you. Instead, just look at the weight of the evidence - unbuffered is preferred over registered:


registered only:
AMD 762

registered or unbuffered:
Micron Samurai DDR
VIA KT-266

unbuffered only:
ALi MAGiK 1
ALi Aladdin Pro 5T
AMD 761
AMD 771
IBM Summit
Intel 845B
Intel 870 (?)
Micron Samurai K7
Micron Mamba
Micron Shogun
Nvidia nForce220
Nvidia nForce420
Nvidia Crush17
Nvidia Crush18
Serverworks Severset IV
SiS 635
SiS 635T
SiS 640T
SiS 735
VIA Apollo Pro
VIA Apollo Pro266T
VIA PM-266T
VIA P4X-266
VIA P4M-266
VIA KM-266


By the way, the knowledge that the 762 doesn't support unbuffered definitely reduces my interest in the chipset. Instead, I'm going to wait for the Nividia solution.
