Hi all, I bought a server dell r210 the 1st series with xeon x3430 processor

just arrived (it only had 1 bank of 2gb ram) I immediately proceeded to buy other banks of ram to form a total of 8gb (4 x 2gb)

while waiting having his twin brother in the house r410 that mounts the same type of ram I took the missing benches from the latter (so as to be sure that the benches were working)

as soon as I turned on the server I started to have problems with the ram reading (membist error on dimm a3 and a1) thus re-matching the reading to the only 2 banks left.

needless to say I tried to move banks etc to no avail, ditto with bios reset and its refresh.

however, starting operating systems such as windows server, however, he sees the 8 gb but says that it is possible to use only the 4 gb

advice?
