My motherboard has a setting for PCIE X16 link retrain. Any ideas what that
is?

Using Intel mb D915PBL and ati X700pcie.

The only reference I found is on a German website. I'll leave it
to you to figure out Babel's translation. Sounds like it's best to
leave it set to Disabled for nVidia cards, and for ATI?:

nVidia's TurboCache of BIOS expenditure-brakes

With a short test it noticed to the computer journal C't, where
nVIDIA's GeForce 6200 with 128 MT TurboCache and ATI's
X300 with comparable hyper-MEMORY function were tested,
that nVIDIA's TurboCache had far been subject to technology
of ATI among other things with FarCry the hyper-MEMORY.
As turned out later, this was located at a bio its position of the
Intel test boards with i925X and i925XE-Chipsatz. Causing for
the power loss of nVIDIA's TurboCache the Bios function
"PCIe x16 link Retrain". After one had changed this function
over from "GXF Card" to "disabled", the GeForce 6200 with
TurboCache obtained approximately equal high values, as the
X300 with hyper-MEMORY. At Doom3 and unreal Tournament
2004 the TurboCache map with the changed bio its position even
exceeded an adequate X300 with 128MB local memory and
128Bit memory binding. The short test mentioned above appears
in the C't expenditure 9/05 (for Monday, 18 April in the trade).
Further test results and background are in the C't expenditure
10/05 to be stated. Source: heise.de Posted by Atte>
 
Here's another one:

How heise later announces to a test c't, a NVIDIA GeForce 6200
with TurboCache can cause substantial trips with a Intel Mainboard
with i925X or i925XE-Chipsatz with wrong bio its positions. So the
used diagram map with the TurboCache technology with plays e.g.
FarCry in relation to the comparable memory technology
hyper-MEMORY of ATI with a Radeon X300 was remarkably
slow. This was the case, if the BIOS option "PCIe x16 stood left
for Retrain" on "GXF Card". Meanwhile the option by "Disabled",
obtained also the NVIDIA Grafikkarte is deactivated approximately
same values. At unreal Tournament 2004 the TurboCache map in
the test even exceeds an adequate wheel on map with X300 with
128 bits data bus and 128 MByte memory. Obviously only Main
boards with Intel Chipsatz with this BIOS option are concerned.
With our test with AMD hardware no such problems arose.
