    GL503VS Memory Upgrade reduces Bus Speed

    Hello All,

    I just picked up the GL503VS-DH74 Scar Edition. I also picked up some Patriot 16GB DDR4 sodimm to upgrade the single channel memory, to dual channel.

    Unfortunately, I noticed the buss speed dropped to 2133MHz?! I've looked through the bios and intels XTU utility, and there is no option to change it back to 2400 MHz.

    Mine did the same thing. I believe it’s because the system BIOS is not set to take advantage for the XMP profiles on the new memory modules.

    You did gain on the CAS Latency though, same as me. I actually get better synthetic scores vs the stock ram even though we are down 270mhz.*
