DH800 Positives:
-adjustable vcore in bios up to 1.6v (so i can lower the vcore w/ a quick reboot if it's a hot day)--ncch-dl has no vcore adjustment, but you can pin mod for more voltage
-easy temperature / voltage monitoring in windows, w/o using cpu resources (the ncch-dl temp monitoring uses 5-10% of cpu resources and you can’t use clockgen at the same time)
-easier to install heatsinks (backplate is screwed into board instead of taped, and it fits in only one way, so no weird aligning to get it in)
-better placement of 24pin power connector (at top, instead of bottom for ncch-dl)
-max of 2.9v for VDIMM, versus 2.8v on the ncch-dl
-can boot at 201+mhz fsb with high mulitplier xeons (2.66-3.2ghz xeons)...you can only use 2.4ghz or slower to boot at 200mhz+ on the ncch-dl
-higher max fsb, if you can get it stable (the ncch-dl only goes to 233mhz)
DH800 Negatives:
-costs more, and it's even worse if you want more than the 2-port RAID
-doesn't restart properly, must use reset button after shutdown from a restart
-no onboard 4-port promise RAID, ncch-dl has 2-port intel and 4-port promise SATA RAID—DH800 does have 2-port Adaptec RAID
-almost no clearance between bottom cpu heatsink and agp video card, so using a VGA-silencer cooler for 9700pro was not possible
-had to pin mod the sockets with two pins per socket in order to boot at 200mhz fsb
-manual really, really sucks...very little important, basic information (like fsb jumper settings--i had to use 2cpu.com to get the jumpers correct)
-doesn't report actual VDIMM, no sensor for it
Other comments:
-exactly the same overclock with the same cpus at 1.6v for both...3.5ghz (4x prime95 stable), will benchmark at 3.57ghz max for both, but not prime95 stable
-at precisely 200mhz fsb, windows runs at 100mhz fsb, for half the final clock speed, even though the post speed is correct (doesn't really matter though since at 201+mhz, the final speeds are correct in windows)---this can be a benefit (only on rev. 1.0), in that you can boot at 201+mhz with higher multipler cpus, like the 3-3.2ghz xeons
-DH800 will not run cas 2,3,2,5 in windows, even when set in the bios, unless you force it with Tw865 program or use 166mhz jumper settings....instead the memory runs at cas 2.5,3,2,5, even though the spd ratings for the RAM are indeed 2,3,2,5---however, benchmarks (PCmark2004, Video encoding, SuperPi) were the same for both dh800 and ncch-dl
-haven't tested final highest fsb speed yet, will test and report later…note that if you can get it stable, the DH800 has the option of higher than 233mhz fsb, which is the limit of the NCCH-DL
So the decision over which board is best for you...is up to you
