My Dual Harper - Asus Z7S WS living review *56K warning*

[Syndil]

If it's not a bother may I ask what CPU's you've been running your Kingston PC2-6400 RAM with? I hear this board is quirky with 400MHz (1600MHz effective) FSB CPU's and was just wondering whether you were running PC2-6400 RAM at 800MHz with 1333MHz or 1600MHz FSB CPU's?

X5482, 3.20GHz, 1600MHz FSB. But the Kingston KTA-MP800K2/8G I am running now runs much cooler than the Hyper-X did.

More effective in this case means it does something other than insulate the ram. Ramsinks are generally worse than nothing..

Generally, I would agree. But in this case specifically (referring to FB-DIMMs and Hyper-X ramsinks), I definitely disagree. They work as intended, and I wouldn't run my FB-DIMMs without them unless I did have a RAM cooler--which I don't and don't need thanks to the Hyper-X ramsinks.

Wow, so you've been running a 150W TDP CPU x2 in a Z7S WS and your VRM is yet to blow. From everything I've read that's a miracle. I guess you must have a fan blowing over the VRM section, are lucky to have a board sample with "good" components or your board revision isn't 1.03g. I doubt the 0501 version BIOS has any effect on the VRM.

Put heatsink on buffer chip, thats all that needs it. Ram just gets insulated and soaks up more heat from the buffer chip with normal ramsink styles

No, read a few posts back. Mine didn't "blow," but the VRMs for CPU0 did indeed fail. Didn't burn up or anything, but one of them started ticking, and the board would not boot at all if CPU0 was present. My board is now running with only CPU1. I figure it's only a matter of time until the VRMs for CPU1 fail as well.

Yes, it does indeed need it, and that's exactly what the Hyper-X ramsinks do. They have a U-shaped heatpipe in contact with the AMB, taking the heat up to radiating fins. The rest of the chips on the FB-DIMM are not connected to the fins.
