MIPs Ram Freezer 4
turned up first thing this morning so i set about getting it fitted but ran into problems right off the bat
Basically once i got the stock heat spreaders off the Hynix HYMP512F72CP8D2-C4/Y5 Ram
it soon became apparent that the centre processor was 1.2mm higher than the memory chips either side.
Hmmmm........after much head scratching i decided to shim the memory and as luck would have it i had some cheap aluminium heat spreaders which just so happened were 1.2mm thick and already had thermal pads on them.
So i set about cutting eight of them in total (two for each stick of memory) down to 50mm x 15mm which fit perfect.
Just a case of adding them and a little AS5 to the reverse side of the memory and and assemble as normal.
Leaving the actual RAM hex bolts loose so the four individual memory stick could move from side to side in the slots, the whole unit then fitted straight into the board with no problem at all then the hex bolts tightened up.
All in all a bit fiddly but well worth it as it's one of the best machined blocks i've laid eyes on in a long while.
I'll let MIPs
know of the issue with this particular RAM so they could maybe machining some heat spreaders for this memory which would be easy for them to do and make life much easier for anyone else in this situation.
Still not linked hose up yet but its been running fine for the last few hours so all is well but looking forward to see if it actually works.
Also today, my good mate Tom also picked the 2 chassis up this morning and it should be back here Tuesday so i can start getting it re-assembled(mines the black one)
Anyway, a few pictures as usual..........BTW the 3rd but last picture shows the copper/brass version along side the copper/brass nickel plate one i'm using.
