I recently got 2 x 4gb Transcend 1600Mhz rams from one of my uncle for free as he was upgrading Im having a i5 4590 pro and Msi Gtx 660 oc vga. Will these two rams be good enough for gaming ?? i mean it got no heat sink or anything on it.just the plain ram cards.so wil it get heat quickly and cause any lag or any issue with the gaming ??
