CX3-20f, the cache and empty slots

its worth trying it. but you will have to match tech spcs of the the existing ram (its SDRAM, may or may not be buffered)
but chances are that the embedded kernel is programmed to ignore the additional ram you put in.

hi,

I don't think that would be recommended. even if you added new RAM ships in the slots, the FLARE of the CX3-40 wont support it. Adding to that real compatibility issues.

It's also ECC

Has anyone actually tried it? I realise it wouldn't be supported, but I am only curious about trying it on a muck-around CX3-20f anyway. We use it as a VMware lab.

Might be a cheap way of beefing up the performance.

you can be the first one to try it
remove SP-B, use chips from that SP in SP-A and reboot with just SP-A...
if navisphere comes up fine, you are all set! you can then buy identical spec chips from market and go ahead on both SP

you can actually use a null modem cable to check the SP post display...it will show the correct amount ram detected by the SP at bootup. If the ram comes up there but not in navisphere, most likely that EMC has put in code-check in FLARE to ignore additional ram (SP looks like a custom made intel mobo anyways...)

I guess same SPS part number is used for all CXs...same might be case for CX3s....in that case the SPS wouldnt run out of juice...unless he puts in too much of ram

i'm not sure if the FLARE can use any extra memory or not but if it can the SPSs might not be able to supply power to SPE and DAE OS long enough to distage extra cache in case of power loss....
