Improving ext4: bigalloc, inline data, and metadata checksumsImproving ext4: bigalloc, inline data, and metadata checksumsPosted Dec 9, 2011 13:53 UTC (Fri) by james (subscriber, #1325)In reply to: Improving ext4: bigalloc, inline data, and metadata checksums by nix Parent article: Improving ext4: bigalloc, inline data, and metadata checksums
AMD processors since the Athlon 64 all support ECC, and most Asus AMD boards (even cheap ones) wire the lines up.
Even ECC memory isn't that much more expensive: Crucial do a 2x2GB ECC kit for £27 + VAT ($42 in the US) against £19 ($30).

I agree. The last 3 motherboards I have bought were for AMD processors. I bought a 3 core phenom II, an asus motherboard, and 4gb of ECC ram for around $200. I have no idea why Intel only supports ECC on their server motherboards. For me, this is a critical feature. In my experience, many Gigabyte motherboards do not support ECC, so check the motherboard manual, or list of supported memory before buying. In fact AMD supports IBM's Chipkill technology which will detect 4 bit errors and correct 3 bit errors. In addition, my Asus motherboards support memory scrubbing, which can help detect memory errors in a timely fashion.
If you buy assembled computers and can't get ECC support without spending big bucks, it is time to switch vendors.
It is true that ECC memory is more expensive and less available than non-ECC memory, but the price difference is around 20% or so, and Newegg and others sell a wide variety of ECC memory. Mainstream memory manufacturers, including Kingston sell ECC memory.
Of course, virtually all server computers come with ECC memory.
