Full ECC support?

Question

Do the Nvidia Nforce3-250 motherboards like the K8N Neo2 Platinum support ECC?  The manual mentions compatibility with 18 chip dimms, and that they "are compatible".  ButI didn't find any mention in the manual of the ECC functionality, and the BIOS doesn't seem to have anywhere to enable/disable ECC support.
I also checked the http://www.msi.com.tw/program/products/mainboard/mbd/pro_mbd_trp_list.php
URL, but it didn't help clarify the situation.
I'd like to assume that ECC works, but with a different manufacturer it turned out
ECC dimms worked as in the system could use the available memory, but the
ECC functionality was ignored.j
Will ECC work fully, as in single bit errors are corrected, and double bit errors
are reported?

Answer 1

Don't remember this now.
Anyway i have not heard of anyone that has tried it , so i guess this is still
a not confirmed issue .
What's interesting is that crutials memory selector doesn't come
up with any ECC memory for K8N Neo2 .
http://www.crucial.com/store/listparts.asp?Mfr%2BProductline=MSI+%28Micro+Star%29%2B+Motherboards&mfr=MSI+%28Micro+Star%29&cat=RAM&model=MS-7025+%28K8N+Neo2+Platinum%29&submit=Go
It states this :
Information on the
MSI (Micro Star) MS-7025 (K8N Neo2 Platinum)
184-pin DIMM Banking: 4 (4 banks of 1)
Chipset: nVidia nForce3
DDR SDRAM Frequencies: PC2100, PC2700, and PC3200
Error Detection Support: Non-ECC only
Graphics Support: AGP 8X
Max Unbuffered DDR SDRAM: 4096MB
Module Types Supported: Unbuffered only
Supported DRAM Types: DDR SDRAM only
USB Support: 2.x Compliant
Can not see that any other memory than non ECC unbuffered is on the
memory test list at msi either .
Memory selector at corsair does the same :

Facts about this Chipset
The NVIDIA nForce™3 250GB Professional platform chipset, NVIDIA revolutionizes professional motherboard designs, delivering a single-chip motherboard solution designed specifically for the 64-bit AMD Opteron™ processor, with a DDR 400/333 Unbuffered solution.
It does not come up with any RE / ECC modules in the compatible memory support advise .
I would choose to trust the memory vendors , as some like theese have started to test modules on different mobos .
I have noticed that corsair has tested registered ECC with Asus SK8N with Athlon FX/opteron .But this is a NVDIA nForce 3 pro150 socket 940 board.

The CMX1024RE-3200 is a 1 GByte, two bank, ECC registered DDR SDRAM DIMM. This module was
developed specifically for AthlonTM 64 FX motherboards. It is ideal for graphics applications that require
large memory arrays as well as for memory intensive games. It offers an unprecedented combination of high
speed and high density in a registered module. This part has been tested extensively in the Asus SK8N and
other Athlon 64 FX motherboards that support registered memory. This module is also available in matched
pairs of TwinX modules tested as a set in a dual channel DDR motherboard.

 This product has been specifically designed for use o n the AMD Athlon64 FX Socket 940 platform and should not be used o n any other desktop platform. AMD Athlon XP and Intel Pentium 4 users should not purchase this memory for use o n their systems. This product does not work with Socket 939-based mainboards, as they are not compatible with Registered memory.
