TheChasman,

Actually the revisions are as follows;

7HNGV - TRPM V4

3GCPM - TRPM V5

G1CNH - TRPM V6

So your board is the 4th version of the motherboard. Now you can try the newer revisions, but if there is something installed on the server that supports only the V4 then you could have issues. 

Now with not finding any of the 7HNGV boards, you may try looking for part 0RFD1 (it is the svc kit that includes that board)

Hope this helps.

One other question - is there any kind of online documentation that actually shows the different motherboard versions for each series, i.e. all motherboard revisions for the T620, all motherboard revisions for the R720, etc. 

It would make it much easier for everyone to look up a code to see what they have and compare it to what might be available. 

Thanks!

Thank you Chris, I really appreciate the information.
