Firstly, thank you to anyone reading this with a helpful intent, I’m very grateful to have a good online community to turn to in such times.
My system specifications are as follows:
AMD Ryzen 7 1700 @ stock
GIGABYTE AB350-Gaming 3 with latest F5 BIOS
Corsair LPX3000 8GBx2 DDR4 memory (does not run above 2166 L)
MSI RX480 4GB
Corsair RM750x Power Supply
Samsung 850 EVO 250GB SSD as OS/Applns drive
Western Digital 1TB 7200RPM Blue Hard Drive
Windows 10 Home x64 Operating System
My problem is as follows:
On installing windows, everything worked great. I installed Far Cry 4, Fallout 4 and Wildlands, all worked very well: Far Cry 4 @ 50-70FPS Very high settings, Fallout4 @ 45-60FPS Ultra and Wildlands @ 45-55FPS Very High settings, all on 1080p. I shut down the machine, and on restart all games had degraded, FC4 gives nothing above 20 FPS, Fallout4 stutters wildly, and Wildlands just crashes. I run a basic CPU-Z benchmark, single core scores ~2000, as expected, and multicore gives barely 5000. I check that R7 1700 generally gives 16000 on this. Checking in the task manager, CPU-Z also peeks processor usage at 45%. I enable the High-Performance power plan, reinstall display drivers, and even uninstall the processor from Dev Manager and restart: no luck. Desperate, I reinstall windows: all back to normal. CPU-Z @ 16000 and FPS back to old levels. I shut down and restart the machine, still all good. But then after gaming, CPU-Z drops back to 5000 score, CPU usage to 45%, but I recheck FC4 and it’s still solid. So CPU-Z and FC4 are not related, hmm. Relieved, I call it a day.
Next morning the computer boots, Windows informs me it’s corrupt, and a GIGABYTE splash screen stating, “ATTEMPTING REPAIRS” sticks around for a bit. Restarts then, performance degraded as before. Exasperated and in no mood for this, I reinstall windows, all back to normal once again. I spend the day shutting down the rig, switching off the mains and restarting. All stays solid. I get SiSoft Sandra and Cinebench R15. Benchmark over 10 times throughout the day. Cinebench consistently gives chart topping performance, a CPU score of 1350+ every time. The Cinebench OpenGL test does the same, top performance on the small list they display to the left with a score of 80+ FPS each and every time. FC4 stays above 70 FPS. All good. The system has been cold booted several times, benchmarked several times, all seems solid. I start the computer at night: performance degraded, Far Cry 4 back at 20FPS, CPU-Z at 5000 multicore. But here’s the funny thing: Cinebench sticks to its old scores of 1350+ CPU and 80FPS+ GPU. Once the GPU score dips to 76, but then stays above 80 consistently after that. I use DDU to remove the display drivers using Windows Safe Mode and re-download and install them: no luck. High Cinebench score, ultra-fast bootup and systems response. Far Cry 4 degraded heavily.
It’s late and night and I need to work the next day, so I give up for the day. I come back today evening, and check what’s up, Cinebench R15 CPU test gives 1367 (perfect), the OpenGL test gives an all-time high of 93FPS. Curious, I try Far Cry 4, it’s back to 55-70 FPS. CPU-Z? Single core: 2000, multicore: 1800!
Really, what is going on here guys? I’d be so grateful to anyone shedding some light on what this could be. I also changed the PSU cable and plugged it the GPU into a different power slot: nothing had changed last night. I don’t understand what’s wrong because if there were a hardware problem, how would it do so well with CPU & GPU @ 100% use on Cinebench, but suck everywhere else?
While it’s working well now, I don’t want to wait to be bewildered by another random screw up…insights and help please!!
