Ive just tried to update a HP 8000 elite The memory is 2gb 2rx8 PC3 10600S-09-10-f2 M471B5673EH1-CH9 1014(samsung) I added some kingston memory same spec as the 2gb 2Rx8 PC3 1060S-09-10-f0 This actually worked for 4 reboots but when i turned it on after the 5th i got a hdd red light flashing and a beeping noise(error). Took the slot and all worked well again. I then tried to put in 2GB 2Rx8 PC3 10600S-09-10-F2(samsung) but number M471B5673FH0-CH9 1030,into the spare slot. This created another error with the top memory, Where am i going wrong here ,i thought it was just about type and amount and channel number.????? Ive done loads of memory in the past and not had problems.Even a shop recommended the kingston one to me which did work for a spell but after approx 4th reboot went into error. Am i missing something here.????? Help appreciated thanks.
