It's not the mainboard. It's the processor.
The memory controller is on the _CPU_, _not_ the mainboard or its chipsets. There are literally 368 traces on a Socket-939/940 mainboard to its DIMMs -- 2 sets of 184-pin DDR.
AMD Socket-939 uses Unregistered AMD Socket-940 uses Registered
AMD Athlon 64 are configured to use non-ECC AMD Opteron are configured to use non-ECC or ECC
So if you want unregistered ECC, get a Socket-939 Opteron If you want registered ECC, get a Socket-940 Opteron If you want to use unregistered, non-ECC, get Socket-939 A64
The BIOS/POST/ACPI is going to be so configured, respectively, on Socket-939 and 940 mainboards, depending on what CPU is inserted. There may be "hacks" to support otherwise on some mainboards, but I seriously doubt it is well supported/reliable.
AMD is very anal on this product alignment.
didn't care...I guess this is a low end board or
whatever...
No offense, but obviously. ;-> You don't use desktop mainboards for servers. It's the reason why I won't buy a Sun SunFire X2100 either.
only thing I know is that Mach Speed is the only MB around that gives a lifetime warranty but so what...
I typically _avoid_ TigerDirect for various reasons. Their overmarketing of crap is a big one. ;->
so that was my point and I thought maybe some of y'all
might
find that interesting as I did... Don't use ecc memory...Wow!!! blew me away!
Not if you know the first thing about how Athlon 64 and Opteron differ from AMD's strategy. ;->
Furthermore, many Intel desktop chipsets/CPUs do _not_ support ECC either. But with AMD, it's the CPU itself -- *NOT* the mainboard.
I wanted y'all to hear this
Actually, you're just introducing false assumptions/information.
For servers, use AMD Opteron. They have Socket-939 single socket (including dual-core) versions now that can use lower-costing, unregistered, ECC memory.
