pc in question is the sabertooth in sig below.

case cooling is accomplished by two phantek ph-f140hp's intake and one ph-f140hp exhaust, h100i is push/pull using four corsair high performance sp120's.

msi kombuster 3.3.0 running gpu core burner v2 (furry donut) sli for one hour records the max temp for gpu1 @ 88 deg c, gpu2 @ 76 deg c.

in game i've never noticed gpu1 over 80 deg c (gpu2 lags 10 to 12 deg c behind).

the sabertooth pcie layout is:
x1 #1 - creative zxr (top of mb)
x16 #1 - 780 ti (gpu #1)
x1 #2 - empty
x16 #2 - 780 ti (gpu #2)
x1 #3 - empty (but covered by video card)
x16 #3 - empty (bottom of mb)

i would like to free up space around gpu #1 by moving the zxr to the bottom x16 slot (#3). the question is does populating the 3rd x16 slot with a sound card lower the other two to x4 (they currently run at 3.0 x8)?

thanks for any help!

If this is the sabertooth in question then according to the specs the 1st 2 PCIe slots are 3.0 whilst all the others are 2.0.

• Expansion Slots2 x PCIe 3.0/2.0 x16 (x16 or dual x8) *2
  1 x PCIe 2.0 x16 (x4 mode, black) *3
  3 x PCIe 2.0 x1

*2: PCIe 3.0 speed is supported by Intel® 3rd generation Core™ processors.

*3: The PCIe 2.0 x16 slot shares bandwidth with PCIe 2.0 x1_1 slot, PCIe 2.0 x1_2 slot and PCIe 2.0 x1_3 slot. The PCIe 2.0 x16 slot default setting is in x1 mode.

So it shouldn't affect the 3.0 slots. You may even find a setting in the bios to turn it get it to run in 4x mode instead of 1x.
