What board do I need so I can use REGISTERED ECC DDR?

I've been made an offer on a pair of 1024MB sticks - but they're ECC so I'd have to find a board that will take them. Any suggestions?

This is the STICK

Looks registered to me....

From what I've read, most VIA chipsets from Kt266 and up DO support ECC.... any confirmation?
I'm hoping for AMD SocketA! Affordable.... anything else = too expensive.

Cheap or not, I'm blowing the bankwad on 2GB of this stuff!

Would THIS board work? AMD 761 chipset... a little older, but IIRC, it should support registered ECC - right?

Whew..... forget that option then. I'll just stick it out with 1.5GB in 3x512MB of el-cheapo DDR ;)

Uh, would you consider selling them?

As for your question, there is a difference between acceptingp them and actually using the ECC.

It actually makes a bigger difference whether they are registered/buffered or not. Are they?

I would use them in my i875 board.

Yes, as long as they are ECC only and not Registered with ECC, most mobos will use them and just ignore the ECC bits - you might have to change from automatic to manual RAM settings in the BIOS to sneak them in.
. Many Intel chipsets both have ECC support in them and the feature is passed on to the end user. Most Via chipsets since the KT266 have ECC in them but the feature is seldom passed along to the end user. Only the Tyan KT400a based boards (S2495AN/ANRS) have supported ECC to the user in recent memory. None of the other Socket-A chipsets (SiS, Nvidia, etc.) even support ECC. The Tyan board also has 4 memory sockets (oops, HAD 4 sockets - looks like they pulled one in recent production - probably as a money-saving measure) and also suports Registered memory so that all 4 RAM slots can be safely filled... Perhaps Buy.com still has some (try froogle.google.com to search for other sources) - I think they have been DC'd.

Finding out now... I just scored a SUPER deal on a pair of 1GB PC2100 ECC's! :D If I can find a board that'll work well with them, I'm in great shape!!

Are you saying most Intel boards will accept Registered ECC? The guy selling them says "they don't work with my board" - awaiting chip make/model info.

Nothing wrong with Intel - especially the latest CeleronD's and such! :)

The Asus i875 boards will accept and use it, that is what I am using right now (P4C800-E Deluxe).

Asus i865 boards do not use ECC RAMs. I am not sure they accept them, but I assume yes. Obviously, there are no ECC modules on the certified vendor list.

Potential list so far:

Tyan expensive board,
many i875 boards....

Keep 'em coming!

Well, unfortunately the i875 boards will not be happy with PC2100.

I think the best option is probably a Xeon off ebay.

EDITed: wait, two PC2100 should give you the RAM for the 533 MHz FSB Pentium-4s or Xeon.

Whew.... i875 is super expensive too. :( I think I'll give up on ECC, no matter how good of a deal.

If you do a google on- linux ecc -you will find a database of chipsets that support ECC. Then you just have have to find a mobo that delivers on what the chipset offers. Generally only server mobos will support Registered AND ECC (except for many Intel and the Tyan Socket-A mentioned above) - almost any mobo will use ECC ONLY modules, you just won't get the value from them - as I said above. It is REGISTERED modules that will cause a problem. ONLY those mobos that specifically say they support REGISTERED (buffered) modules will even run with them!!! ECC is in the chipset AND the mobo design, registered is in the mobo design only. A lot of sellers "forget" ;) to mention the Registered part...
. If it were me, I'd buy the Tyan mobo - perhaps you can find one used on ebay or one of the techie forums. You will save enough on the CPU to make up for the higher mobo cost...
. There is a dual Xeon on compgeeks for a low price.

Here's the Xeon board:
http://www.compgeeks.com/details.asp?invtid=S2720GN

I can't fidn the actual spec but I think this one only gets you dual-chanell with 2x200 MHz -> 400 MHz. If you have 266 MHz RAM it will not give you 533 MHz dual channel.

Still, pretty cute. I am not sure what processors you need, but probably a Prestonia. Not sure where a socket 603 fits with 133MHz bus.

. Many 761 single processor socket A mobos support ECC (like the 7KJD and the Gigabyte that newegg has in the refurb section for <$30.) But I looked at the manuals for both the mobos and neither mentions anything other than ECC (Chaintech calls it Parity - incorrect terminology - ECC NotEqualto Parity) . However, I went to the Crucial configurator and it says that both boards can use Registered as well. Go figure...
I wonder if Crucial or Kingston could provide a reverse lookup on their memory configurators where you could enter the memory you have and get a list of mobos that can use it...

Dangit... The AMD board is sold out. I have to find something from VIA I guess.

I found

I could get the EPOX 8K5A2+

I see ECC in the list of accepted RAM! It says Unbuffered ECC for those chips... is that equal to the Samsung chips I linked to earlier?

Boy... all this effort just for being unable to afford new RAM! :(

Zepper... you get my vote for ELITE! :D

The samsung modules you linked to are Registered AND ECC - for server mobos or a rare few single-processor boards like that Tyan, Chaintech or the Gigabyte mentioned here.
. Too bad you're in Canada, that $30. refurb Gigabyte mobo (GA-7DX+) on newegg could handle those. But considering the low price, it probably is a bare board. Maybe you have a stateside friend that could act as middleman...
. You may have to settle for the standard RAM.
