I'm pretty much completely new to the idea of overclocking. Just bought a GTX 970 and the bottleneck is really really bad. Getting scores way below what I should be getting with a decent CPU.

So I have two choices, buy a new CPU (I have AMD and would preferably just buy a new mobo + cpu intel combo) or overclock the CPU.
Now there aren't any really good deals that I know of (if someone knows of one, please link it) so my only choice is to overclock atm.
Can anyone give a detailed guide on how to overclock the CPU?

Also how safe is overclocking? Will it reduce the life of the CPU in any way?

Side note: I have a corsair h105 cooling my CPU if that is at all important.

No I haven't. For the specs, check the CPU-Z validator sig attached for the to my posts. I just updated right now with my current specs.

Also, here is my Unigine Valley Benchmark scores.

I comared them with a review of this card and they are getting a score of about ~4200 with this card.
I benchmarked with another computer (i5-4670 + EVGA GTX 770 OC) and it got a score of ~3500.

Hmmmm - no power supply! No wonder you don't get good performance.

You won't have to OC a FX8150 to get the gtx970 to run flat out.

From Task Manager, what's the max CPU %usage?

Seasonic M12II 620 - nice one!

From Task Manager, what's the max CPU %usage?

From bios/uefi, what the CPU temp - at idle and while gaming?

Idle temp is about 19C and gaming temp goes to 41C max but usually stays around 34C.

on Dead Rising 3 I saw about 54% usage and on Shadow of Mordor it was around 45%

So your CPU isn't the problem. Its not bottlenecking your PC performance. And it won't need overclocking.

What %usage is your 970 running at from Afterburner?
What voltage is it running at?
gpu clock speed?
memory clock speed?

Used heavily modded Skyrim to test this one.

GPU-z and MSI afterburner gave same results so I just used GPUZ results since it's all in there.

Here they are:

OK - so your 970 is running flat out. And at 70C. At good clock speeds.

What fps are you getting? At 1080p?

I'm using the Natural Lighting and Atmospherics ENB with various texture mods. I get pretty low fps in Riften but average would be around 45-50 at 1080p.

Do you know what might of caused the low scores on Valley?

No - I don't use it. There's probably a forum for Valley that you can put your results on.

please run the unigine valley benchmark on the extreme hd preset. unigine valley has virtually no cpu load that will expose a bottleneck.

skryim is notoriously cpu intensive, it wants 2 threads going really fast.

yeah something isn't right. 2000 is about the score of a 680/770/7970/280x. my highest valley score with my 780 was 3389 with a rather high 1375mhz core clock. you should be very close or higher than my 780.

what graphics card did you have before?

http://www.wagnardmobile.com/DDU/downloads.html
download ddu. let it run the safe mode clean restart recommended for nvidia. if you had an amd gpu in there before you should run it for amd too. then reinstall the latest nvidia drivers and retry the benchmark. at least we can rule out driver conflicts.

AMD 7870 Black Edition Double Dissipation.

Could it be that I am running it on a 2.0 pcie instead of a 3.0?

no. pcie lane speed has nothing to do with it. run display driver uninstaller to make sure there are no video driver conflicts.

Ran the display driver uninstaller twice in safe mode. Once to clean up AMD, then again to clean up the NVIDIA one. Then restarted in normal mode and installed fresh NVIDIA ones. Re-ran Valley at the same settings and the score is approximately the same.

well you did get a gain, but something still isn't right. here is one of my scores...

Could it actually be the 8150 bottlenecking me? But you said this bench would not expose CPU bottleneck right?
The other computer in the house has a 3670 + 770 and scores about 3500. So I'm assuming it is, but then again could be something else.

the 770 will not score above a 2400, and thats a very very high overclock. the bench shouldn't be cpu limited since many use dual core i3s and titans and achieve similar results. im not too familiar with amd overclocking but the basics of getting a modest overclock are fairly simple. you have a great cpu cooler too so you should be more than fine with a decent overclock.

Do you think you can teach me or know of any good tutorials on how to overclock properly?

i know there is a northbridge and ram you can play with but just for starters you can move the multiplier/ratio up since this is very easy.

you will need to download a monitoring program to check cpu temps and voltage... many just use hwmonitor. then you need a stress testing program, i like prime95 and intel burn test. intel burn test is quick and dirty and most of the time its a fairly good indicator of stability(or very close to it). prime95 i like to use as the final stability test by letting it run overnight or for about 12 hours. most agree if you can make it through 12 hours of the small fft test in prime95, your stable. but intel burn test in my experience fluctuates voltages faster and quicker, and also heats the chip up quicker for quick 10 minute tests so you dont have to baby sit a test for hours.

someone else with an amd fx chip should chime in, but i do believe many say dont let amd chips get above 65c. so if at any point during prime/ibt testing the hwmonitor says the 8150 package temp is above 65c stop the test.

otherwise go into your bios and change the multiplier/ratio to 20x and then test with intel burn test. if you pass, go back into the bios and put in 20.5x, i think it lets you do half numbers. anyways, keep moving the multiplier up one increment at a time until you either fail to enter windows or you blue screen running intel burn test. then move down one multiplier/ratio increment and retest with prime95 running the small fft test. and again, if you get over 65c stop the test and move the multiplier/ratio down.

since your not touching any voltages in this initial overclocking, your extremely safe. we are just testing your stock cvid voltage limited overclock. later on after you get a hang for this, and if your still well in the safe temp range, you can start learning about northbridge frequency and manually adding more vcore voltage.... if you choose to. but at any rate, your h105 should have no problem keeping you well within temps on a stock voltage modest overclock.
