Hello

I read  the forum and think I already found out. But want to be sure. Would be very nice if you can help me. I want to upgrade the 4GB module and replace it with a 16GB module





So I wanna buy a 16GB DDR4 2400 MHz CL 17 module

Its just confusing because I always saw CL 15 when i read here in the forum.

    What I would do since your old OEM is an A-Data Technology DDR4-2400 (1200 MHz) Part No: AMIP24HC4R1-BUNS at 4GB ram, I would replace that with the same ADATA DDR4-2400 (17) 16G X16 SO-DIMM 1.2V Part No: AD4S2400316G17-B (see caption) this is a 2400MHz speed, CAS latency: CL 17-17-17 as that is the most sensible thing to do and will match your manufacturer of your OEM type ram and will be the most compatible.

    Thank you very much.

    The only thing I can find here in Argentina is AD4S2400316G17-S

    Does anybody know what is the difference between the B and the S at the end? Or it doesnt matter for my purpose?

    Kind regards

    All the AD4S2666316G19-B or R or S are the same DDR4 SO-DIMM 16GB 2666 with 260-pin, 2666MHz speed, CAS Latency, CL 19-19-19 at 1.2V which what you should be worried about. If you can only find in Argentina the AD4S2400316G17-S then buy that as it will improve your system considerably. .
