After OC: Mouse unresponsive after wakeup

I like playing Planetside 2 but it requires a powerful CPU and my stock i7-2600K just wasn't cutting it. Luckily, it's an i7-2600K and I was easily able to find a stable overclock of a solid GHz. The mobo is an Asus P8-Z68-V PRO and the CPU is cooled by a Thermaltake Frio and powered by a PCP&C 950W power supply, all about 2 years old. I did not mess with any voltages or timings or anything: just boosted the multiplier until it crashed under test.

Anyway, I then found my computer had some trouble waking up after sleep. My computer is in my room and it's in a HAF X case which is LOUD, so I put it to sleep at night so I can sleep myself. I know most people say that sleep doesn't work on desktops but it worked flawlessly on mine. But now it would start, and then reboot completely but resume as if it had simply woken up. So I pushed my clock down until this didn't happen anymore, resulting in the 1 GHz boost instead of 1.3 or so. So here is the current issue:

The PC wakes up fine but when it does my mouse is almost always unresponsive, and Windows (8) tells me a USB device is unrecognized and has malfunctioned. The mouse is a Logitech G9x.

I have not yet tried clocking everything to default yet, because I would very much like to keep the OC, but if it comes down to that I guess it is what it is. I would also be open to alternative standby modes, if there are any.

Thanks you!

The logical first step is to put all settings to DEFAULT.

If the problem goes away, then you had an instability issue caused by your overclock. I think you know that.

The i7-2600K is a nice CPU. If you have game performance issues I would suspect the GRAPHICS side of things, not the CPU.

TESTING:
a) Prime 95 for the CPU

b) Memtest for the System RAM:

Overclocking the RAM accidentally:
It's possible to accidentally overclock the RAM. The BASE CLOCK affects both the CPU and the RAM. If your RAM is already at it's maximum of say 1600MHz and you boost the Base Clock by 20% to overclock the CPU, you may also overclock the RAM by the same amount and make things unstable.

After you change the Base Clock then, look at your RAM settings and change the Multiplier for example so the frequency is correct. Example:
a) 1600MHz correct setting (160MHz x10)
b) Base Clock to 200MHz (RAM is now 200MHz x 10 or 2000MHz and unstable)
c) So change the MULTIPLIER to 8 instead of 10.
d) RAM is now at 1600MHz (200MHz x8).

The above is an example only.

Tweaking:
If frame rates aren't high enough, tweak the graphics settings. There's a lot you can do there.

LOUD CASE:
I can help you there. It's not the case mainly that's loud, it's the FANS. Graphics cards can be the loudest part of your system but usually you can't change the settings.

However, you can usually setup FAN PROFILES to control fan speed for both the CPU and case fans through the motherboard software. If fan control should work and doesn't, you may have a VOLTAGE 3-pin fan instead of a 4-pin PWM fan.

SUMMARY:
- your instabilities are almost definitely overclock related.
- your game performance issues are likely more to do with the graphics
- Find a nice stable CPU overclock and don't push it to the limit.
- Finally TWEAK the graphics settings for the best quality to frame rate balance.

I will try all that soon, but I just want to reply to say:

It is 100% proven, confirmed, and guaranteed that Planetside 2 is far more CPU intensive than it is graphic. Or, more accurately, CPU inefficient. It only utilizes one core to any significant degree so that one core needs to be as fast as possible. I have a GTX 770 so graphics performance is irrelavent, as framerates do not change at all between minimum and maximum. It sounds weird because it really is. The game itself will tell you what component is the current bottleneck and mine is CPU all the time while on the highest possible settings, including PhysX effects. The game is notorious in that way.

@ Fans, trust me, I've tried it. Even at minimum speed the 10+ (well situated, don't worry) fans in this case is still too loud to be 5 feet from where I sleep.

So thank you for the reply, but I really just need to deal with the mouse on wakeup. To that end I will try tweaking my RAM, I suspected that may be an issue. But I am also doubtful this is a result of overclock stability. We'll find out.
