Dell T5600 'reliable memory technology has discovered and isolated errors in system memory'

Recently I installed new memory recommended for the Dell Precision T5600 see below.

2x   SKhynix 16GB PC3-128000 11-12-E2      HMT42GR7MFR4C PB

I was told that these are compatible units for the T5600 - 

Hynix's part number is HMT42GR7MFR4C-PC.  It was resold by Dell with their part number SNPT8XR5C/16G.   

Dell sold these for their PowerEdge R415 and R520 servers, but they will work in many other servers/workstations. including the T5600 but when I inserted them into my system I got error message -

"reliable memory technology (rmt) has discovered and isolated errors in system memory. You may continue to work. Additional errors will not be isolated. 

Memory Module Replacement is recommended. Please refer to the RMT Event log screen in BIos setup for specific Dimm information.

Alert! the amount of system memory has been changed.

To continue press F1 Key
To Change set-up option press F2 key
To Run on board Diagnostics press F5 Key"

I pressed F1 to continue and it worked from there and was working for around 4 days with no problems today I notice the system froze so I shut it down and did a restart to where I found the same error message as above.

"reliable memory technology (rmt) has discovered and isolated errors in system memory ~"

Is there anyone out there who can shed some light or idea of why this may be happening my thought is that perhaps I was advised wrongly and that this is not the correct memory?

Thanks in Advance
