Hi there, i can't find any info about compatibility of Gigabyte GA-H81M-S2PV mobo and Vengeance® — 4GB Single Module DDR3 Memory Kit (CMZ4GX3M1A1600C9). In the compatibility list, there's CMZ8GX3M2A1600C9 ram, which seems to be exactly the same as the one stated above, just being sold as a kit 2x4. Now i guess then it shouldn't be a problem, but i'd rather see someone confirm it. Alternatively i'm open to suggestions for the ones you know are compatible.
