SLI Causing USB Problems

[bullbearish]

I recently rebuilt my machine and reinstalled Win 7. During BF4 play my Logitech G13 keypad and mouse locks up. If I'm standing still, then I can't move for a few seconds. If I'm traveling and turning in a vehicle, then the forward travel and turn continues until the USB responds again after 5 or so seconds.

I've done a Google search and haven't found much. I've reinstalled my USB drivers. The last thing I tried (based on a tip found on Google this morning) was to disable SLI in the NVIDIA Control Panel. Alas, no more USB lock ups.

The relevant components are:

Logitech G13 keypad
Logitech G700 mouse
Asus P8Z68-V Pro
NVIDIA 780ti in SLI
Intel 2600k

I don't want to give up the extra performance I get from the SLI configuration, but the USB lockups make the game unplayable.

Power supply make and model?

Corsair AX 1200

Ah, so there should be no problem with that. Are you overclocking your CPU?

 

[bullbearish]

Nope. Running at stock speeds on CPU and GPUs.

So you're not even using something like "Performance Mode" in the bios?

If not, next step: Have you tried raising the VCCSA voltage a bit in the bios?

 

[bullbearish]

I am using a performance mode in the BIOS. I'm unable to find VCCSA.

I did turn up a similarly named voltage in the bios by 0.2v and it seems to have reduced the number of occurrences. I will now try 0.3 and see if it eliminates the problem.

Turn everything back to stock and see if the issue is resolved. Chances are that "performance mode" is the problem. These type of things are kinda like auto-OC utilities and they don't always work.
