Tradesman1 :
Would guess them proprietary DRAM DRAm that was made for HP or CPU-Z can't read the SPD info
i'm purchasing an additional 4gb ram stick of same latency and frequency, so as to get a total of 8 gb.
i shall then check if the spd shows for that stick. i shall post the result,this will confirm if the hynix ram is proprietary or not.
Hope it does !
