Hello Everyone, I've got a new machine and I maxed out it's ram. The board can take 32 GB of ram and that's what it has. It's running win7 professional 64 bit, (I checked Microsoft and that can take 192 GB of ram), and it's not showing ram right. In system information I'm seeing total physical ram 24 gb, a full 8 short, usable physical ram 16 GB, and available when I look is 14.7 GB. I don't think these numbers are right. The board is a gigabyte GA970-d3 rev 1.4. I believe it's dual channel. I took out the ram chips in pairs so instead of four the system had two, numbers were still not right, got 12 gb of total ram instead of 16. The ram is g.skill 1866 clockspeed I believe but in the bios that's only at 1333. I can't believe I've got four bad chips, or since this came in two separate orders one bad chip per order. I'm now wondering if it's a timing issue, if the ram can't clock down from 1866 to 1333 usually in my experience hardware can clock down one level but not two. I'm going to try a grml 64 USB disk when I return later today see what that shows, and I read it had a ram tester I'll give that a go. I'd appreciate any thoughts or suggestions. Thanks. Dave.
