Hi all.

I found a very good deal on some HP server RAM. Can you guys confirm that they will work with my 4.1? I know they will downgrade to 1066 Mhz.

HYNIX HMT31GR7BFR4C-H9
DDR3 SDRAM PC3-10600
CL=9
ECC Registered
DDR3-1333MHz
1.5V
x 72
8 Bank

Hope you guys can help me out.

Should work but you will have to remove your existing memory as you can't mix registered and unregistered dimms.
