I have GL504GV. it came with one 16gb stick. I added another one with slightly better spec. Runs correct speed in dual channel. Performance increase in games is significant.
I bought off Amazon (I am in Canada). Here is description:
Timetec Hynix DDR4 2666MHz PC4-21300 Unbuffered Non-ECC 1.2V CL19 1Rx8 Single Rank 260 Pin SODIMM Laptop Notebook Computer Memory RAM Module Upgrade (16GB)
CPU-Z still shows the memory as 1333Mhz because the memory is Double Data Rate (DDR) and runs at effective bandwidth of 2666Mhz. CPU-Z shows channel as dual.
The SPD tab shows available JEDEC settings available to use by the RAM chip. The Memory tab will show what is actually being used between the both of them by the BIOS.
I don't see anywhere in BIOS to select the memory timings . Fortunately mine worked. I think Asus BIOS here auto-detects.
Thanks for the information, what memory does CPU-Z say you had to begin with? Mine is a samsung with CAS 19, maybe if I get that crucial with CAS 19 they match better and provide me with 2666, I dont know if the performance suffers all that much but feels kinda dumb to buy a memory that doesnt match as good as possible if there are other ones that do.
I'm getting a GL704GV myself and am planning on getting a 2x8GB kit from Crucial when I can. Just wish it weren't so damned expensive. Never installed RAM modules before so this should be interesting figuring out how to configure it. Lemme know how it works out!
i have now installed and tested with the new memory. It runs in the correct speed and the benchmark result yields 93 fps on max settings compared to 89 before with mismatched memorysticks.
EDIT: Continued testing and getting a consistent 98 fps, so quite a bit improved from 2400 mismatched as well.
