Recently bought a used gt70 with a 680m...I'm in need of help!

Hey all. I just got a gt70 with a 680m. I've experienced some very unusual stuttering. I've found out that my gpu usage fluctuates pretty drastically causing all sorts of fps drops. I think its all related to the previous owner possibly using a vbios. Its really all I can come up with. In gpu intensive games my gpu usage is all over the place. My fps stutters like crazy. Nothing is consistent. I could be looking at the sky or the ground or a large bf3 field of action. Doesn't matter. Yes its plugged in. Yes its running on the nvidia dedicated gpu and not the intel.

 

also i am using "prefer maximum performance" and "adaptive" it doesn't matter. Also my voltages are .987 reg and 1.012 with turbo button pressed

 

the power brick can't take all the load ? or overheat+ power brick throttling !

 

Have a close look at what your CPU is doing and also you can try flashing a different vbios (see tech inferno forums).

Remember to keep it to the MSI vbios.

 

What do your temps looking like? What driver are you running? Is this all happening in one game?

 

ok so i've done some digging and narrowed it down somewhat. it doesn't matter what driver i use. now im using the latest whql drivers. but i realized that the stuttering is far less prevalent when im in normal mode (aka non turbo) and the gpu is drawing only .987 volts. When in turbo its happens a lot more often. It happens in nearly all games and I think its probably happening more in cpu intensive games (just guessing). This sounds like a power throttle? Does anyone know the normal stock voltage of an msi gtx680? and can anyone provide me with a stock vbios backup they might have?

 

not sure man, but here's a good thread about vbios and voltage on the 680m, multiple different bios links in said thread:

My GT70 starts GPU core clockdowns when raising the default 771 MHz to over 820 - 830 MHz dropping the benchmarks clearly under default values. Memory overclock is better tolerated but the benefit isn't so big because the default memory performance is good compared to what the GPU core yields. The turbo on Win8 doesn't work too well - just raises memory from 1800 to 1854.

 

Max voltage on my 680m is .987v when at max clocks. Your 680m is overvolted if it is hitting 1.012. Try to flash svl7's vbios with default voltage.

 

TC, you should also monitor your CPU to ensure you do not have CPU Throttling besides any issue with the GPU vbios. Monitor CPU usage and see if the fps drops correspond to drops in CPU speed.

How are you doing man? You are now more than qualified to help the TC!

 

Turbo mode bumps the voltage up to 1.012 and cause throttle on the stock vbios with clock bouncing, this is standard behavior for the stock vbios and is something the modified bios fixes.
