Have 32GB of Registered ECC - M393B1K70DH0 CK0 Samsung 8GB DDR3 1600MHz, instead of wasting it I would like to make use of it. I have seen a post it says as follows:

32GB 4X8GB RAM Memory for ASRock Motherboards 990FX Extreme4, Fatal1ty 990FX Professional, 990FX Extreme9 DDR3 ECC Registered RDIMM 240pin PC3-12800 1600MHz Black Diamond Memory Module Upgrade." rel="nofollow - The Product Post

Could you please tell me if its compatible, as the specification on ASRock gives no clue as to the compatibility. Here the specs:" rel="nofollow - 990FX Extreme4" rel="nofollow - Fatal1ty 990FX Professional" rel="nofollow - 990FX Extreme9

Oh, in addition to those this one article struck me from 08/07/2012 the article can be found here:,1.html" rel="nofollow - The Article

Can I use the memory M393B1K70DH0 with DDR3 motherboards, are the AMD processor compatible???

I don't know if it would work, but if it works, no ECC would be functional.

Or maybe ASRock TSD thinks different, but IMO, for ECC You need an Opteron.

990FX Extreme 9 MOD P1.70
AMD FX 8120 4GHz 1.25V
Thermalright HR-02
Patriot Viper 2x4GB 2133MHz
Samsung 850 EVO 250GB
LanCool K62 Dragonlord
ASUS Xonar D2X

I'm with ASRock Expert here. I'm thinking you'd need a server class Opteron.

I don't believe an FX-xxxx series will even boot if it sees ECC mem slotted in.

ASRock Staff should be able to answer this question for persons seem to have this config. I have seen it on couple blogs. Can anyone say for sure if it works through testing?
