Yeah, should be around 135fps with a 1080GTX card on Heaven 4.0, that's on the high side with a +134mhz OC to core/+400mhz OC to memory and a 800mhz OC to my 4690k.
I think@ base clocks should hit about 110fps on a 1080.
Computer crashed at 4.5 GHz right away.
Anyway, went back down to 4.3, booted up Prime95 on blend and my PC froze and bluescreened immediately. Seems like a dying CPU to me. "Machine Check Exception". Perhaps that's the reason for my low performance?
EDIT: Running Small EFTs and the thing hasn't crashed yet. Now I'm leading to believe that there's a bad stick of RAM in there that's causing all of these problems in that case. Windows memory tester is useless.
Must say, I get stuttering frequently during playing. The only other time i had this happen was when I had faulty 4870 x2's back in the day with ATi. I don't know if it's really a fault GFX card, because the computer has been doing some strange things lately. For example, when I hold my mouse click down, it'll randomly release and click again on its own. Also icons on the desktop have been resetting randomly too. This just started happening a few days before I installed the GTX 1080. I wonder if it can actually just be the RAM..?
EDIT 2: Running Blend on Prime95 again and it hasn't crashed instantly. Must be randomly cycling through RAM to select?
4.3Ghz should be fine OC for that Cpu, if your crashing @ 4.5ghz just bump the Vcore a hair bit more. Remember its not voltage that ruins processors its degradation from over heating it.
Either way 4.3-4.4ghz should be fine for 1080GTX without a bottleneck.
Too much voltage will kill a processor...and degrade its life expectancy (that dang physics and electron migration!)
There is more to overclocking your processor than just setting a frequency, voltage, booting into Windows and calling it good.
When you overclock your CPU, you should do the following:
1. Memory at stock speeds
2. Get a stable CPU overclock
3. Overclock memory
My theory on CPU stability is to over test it. The last thing I want to have happen is a BSOD...especially during a Windows update...that will bork your Windows and you have to reinstall. I find the limit of my CPU overclock for a stable voltage, and then drop the frequency back by 100 or 200 MHz but keep the same voltage...to make me feel extra special. Overkill...probably...but I haven't had any CPU stability issues in over a year...and my system runs 24/7.
Memory overclock doesn't buy you all that much in terms of performance. It is an improvement, but you get the best bang for your buck by overclocking the CPU.
If you are having trouble overclocking your memory, it could be motherboard limited or CPU. What works good as well is to decrease your RAM timings (many threads on the web about doing this). You lock the memory frequency at where it's happy, and decrease the memory timings to get very close to the performance of higher clocked memory.
For my system (5820 K), I had difficulty overclocking my memory...it was rated to 3200 MHz, but I had issues with stability. So, I brought the memory speed back to 2666 MHz, and decreased the timings by 20%...I got stability that way and very close to the same performance as a 3200 MHz memory clock.
