980Ti Issue

post #1 of 6
Thread Starter 
Hi all,

i'm new to overclockers, but have been PC gaming/building for a good few years, however a problem has me absolutely stumped.

Before I get into details, my rig;

i7 4820k @ stock 3.7Ghz
MSI GTX 980Ti
16GB RAM
Gigabyte UP4 x79 Motherboard
Corsair RM1000 PSU

I recently upgraded to a 980Ti from a 980, which ran absolutely beautifully. However, the 980Ti is seriously struggling.
Heaven benchmark uses about 50-60% GPU at 1440p and is getting far worse FPS than the original 980. CPU is at 20-30% load, so it's definitely not bottleneck in that respect.

However gaming is a new story. As a test, I played Far Cry 3 and 1 core was hitting 100% on the CPU. GPU was at roughly 70%, so getting low FPS in this case, again.

I highly, highly doubt my CPU is bottlenecking the 980Ti as it's a pretty decent i7. As a test, I threw on a stable overclock of 4.2ghz when tested with Prime95.

Booted up Far Cry 3 again, same CPU and GPU useage, same FPS.


Anybody got a clue? Dodgy GPU perhaps?

Thanks in advance.

Nik

I helped some guy in a previous thread who had same issue. But he had not told us if it was a used card or not. His problem was his card was on a custom bios which conflicted with his system drivers but not The seller. So tell us is this a new card? If not try flashing to stock bios. I cannot provide sadly at this time.

Im not saying this is a definite cause rather rule it out first hand now.

Hi Stephen,

Thanks for the reply. This is a brand new card from Scan Computers, so should be stock BIOS already.

Oddly things have picked up a bit. Even though a CPU core is showing 100%, total CPU load is only 30-50.

However the GPU has now picked up a bit to 90+ useage. It sounds crazy but its almost as if the card needed minor burn-in time?

I'm still playing with a couple of tweaks here and there for now though, not to rule out that 'its sorted'. More an observation.

Gpu's dont have burn in. This might suggest its more of a driver problem. To be honest latest nvidia drivers have been flaky. Do try switching drivers thought it is a weird issue that could be anything. Try very latest first 358.70+ uninstall current with DDU. If not id try older way older ones 355.98 just to rule out drivers.

Thanks for the reply chaps.
