What should I overclock my AMD fx 8350 to?
Hi im quite new to pc gaming. My graphics card is an amd HD 7950 and I think my cpu is bottlenecking it. My cpu cooler is a corsair H80i water cooled.

What im trying to say here is should I overclock my cpu and if yes, what to? I don't want to shorten the lifesan on it so I dont want to go too crazy but I would like some fps improvements. At the moment its at the stock 4.0ghz. Should I also overlock my gpu as well?

Any advice would be greatly appreciated, thanks :)

Overclocking is all about trying and seeing what you can get it to. There is no definitive answer for how much you will be able to get and how long that overclock will last. You need to post your computer specs.

hi the cpu should not be bottlenecking the 7950 ive got a 8320@4ghz and a 970 and it does great runs gta v all very high 16xaa 8xmsaa(world,reflections) etc fallout 4 ultra all 1080p.. older games dont fair so well with fx... to monitor which is the bottleneck you should get a program such as hwinfo and run it on sensors in that background to see which one has more usage... although i guarantee if its newer games and the fx is running right its your gpu

as for overclocking that depends on your mothrboard and your case cooling to ensure vrms dont overheat

If you want to overclock, read a guide.

Not all CPUs are the same, even an identical model chip. With overclocking, your milage may vary. With modern day processors, unless you are pushing them to extremes, you don't have much to worry about.

Does overclocking have the potential to shorten the lifespan of the CPU? Sure... but so does playing games, leaving computer on, turning computer off/on, sleep mode, hibernate, using it in general, ect. Anything you do with electronics has the potential to shorten its lifetime. Don't sweat it, don't do anything ridiculous, and follow an overclocking guide.

I'd recommend overclocking only if you have a decent power supply and your motherboard has a decent power phase. If you don't, then just forget about it.

What are your full specs?

Thanks for the replies everyone :) I'm not sure what power supply my pc has and I dont really want to open it up to see just incase I break something. I know for sure that my motherboard is the Asus Sabertooth 990FX R2.0 ATX AM3+ and the case I'm using is the CiT vantage gaming case but as of right now thats all I know. I also have 8gb of ram but I dont think that plays a role in this.

so you can overclock your cpu on that motherboard no problem provided you have even remotely decent case cooling... but ocing the cpu likely wont see an increase in fps as i mentioned the gpu is a bit on the weaker side.. but if you need help ocing just ask almost all fx's will do 4-500mhz by increase multiplier with no vcore increase

i upgraded from a 770 to a 970 and the difference was quite large ive got my 8320 at 4.0 so its the same as 8350...

That motherboard has an 8+2 power phase, so you should be just fine to overclock as long as you have a decent power supply.

Simply opening your case will not break anything... all you need to do is open the side panel. Judging from pictures of the case, there are even thumb screws, so no tools needed. If you have a mechanical drive, I'd suggest turning off the PC first... and as long as you don't go touching things, you should be just fine. Your PSU should be clearly labeled without the need to touch anything inside.

Yeah my power supply is a xfx 750W core edition so I should be fine with overclocking my cpu. Will I see any improvements in really cpu heavy games like BeamNG.drive? If not I just wont bother.

EDIT: for overclocking you should make sure you have all (or at least 3) of your case fan slots filled with good airflow fans that pump at least 50CFM each.

One thing to know, overclocking will void your 3 year CPU warranty. For this reason you may want to hold off. Also I don't think it's bottlenecking your GPU. You may experience better performance gains from a GPU overclock but again this will probably void your warranty.

As for what speeds you can hit well each system and chip is unique.

I'd suggest leaving the base clock alone or mostly alone and only overclocking the Turbo.

Something like one of:

Mild overclock:
Base Clock 4 GHz, stock voltage
Lower Turbo on 4 cores to 4.3 GHz, stock voltage unless unstable
Upper Turbo on 4 cores to 4.5 GHz, stock voltage unless unstable

Medium overclock:
Base Clock 4GHz, stock voltage
Lower Turbo on 4 cores to 4.5 Ghz, adjust voltage as required
Upper Turbo on 4 cores to 5 GHz, adjust voltage as required, not over 1.5V if possible.

Agressive overclock:
Base clock 4.2 GHz, voltage between stock for base and stock for upper turbo as required
Lower Turbo on 4 cores to 4.7 GHz, adjust voltage as required
Upper Turbo on 4 cores to 5+ GHz go for maximum stable speed then back down at least 100Mhz from peak & 5 to 10 degrees C thermal margin, adjust voltage as required.

Please note my recommendations are in no way a warranty that it will work at these speeds, that it will not overheat, that it will not wear out faster or that what I'm saying is even possible in your system. They are merely suggestions of how I'd recommend balancing your overclock between base clock and both Turbo states. Turbo states are supposed to only activate when there is enough spare thermal margin so I believe overclocking using Turbo should reduce the chances of your system ever overheating due to the overclock. Though of course you should do proper stress testing at the highest ambient temperature (using your heater) that you think the system is ever going to have to run in. Basically Turbo should act to balance the stress between cores, to reduce heat and increase CPU longevity.

Running your cooler harder cooling a CPU overclock will reduce the lifespan of the fan and the pump even if the lifespan of your CPU is not reduced. If you keep it cool it will likely live long.

Please understand that the more agressive the overclock the more likely to wear out or break. Also you should download AMD Overdrive (from AMD) so that you can monitor your "thermal margin" and adjust the Turbo clock speeds like I have described. I don't know that motherboards or other overclocking programs will do as good a job. Motherboard usually measures socket temperature while AMD Overdrive measures thermal margin per core. The difference is that socket temperature doesn't help measure core temperature and is often off by as much as 10C. Thermal margin on the other hand measures core temperature and then shows how many degrees C you have of safety margin, meaning high thermal margin is good while low thermal margin is pushing nearer the limit. I guess 0 thermal margin would be the limit and a negative number would be overheating. You absolutely don't want to overheat.

Overclocking your GPU will similarly reduce lifespan of the cooler and possibly also the GPU itself. It will also probably give bigger performance increase. You may be more likely to replace your GPU sooner than your CPU so for this reason you might consider it more expendable even though it's probably also more expensive.

Also you might want to add another +16GB (2*8GB) of RAM into your system just because 8GB is kind of low in a gaming rig at this point. It's adequate for most games but it's nice to be better than needed, to have spare. Specially since running out of RAM makes system performance suffer really bad or even crash all together. It can slow you to a crawl. Most new systems at the $600 to $700 level and above I recommend start with 16GB (2*8GB). Only in the $500 and below systems am I always recommending 8GB for budget reasons.

FX8350, start with, go to bios disable c1e/turbo core/cool n quiet, set cpu voltage 1.35v ish, bump clocks 22x200+4400mhz play around that while monitoring cpu temps, if it runs stable at 4500mhz with in 1.35v ish you'll be fine but it should easily do 4400mhz with 1.35v ish.

Ram, bump it up to 16GB or add another same series manufacturer CLx 2x8GB kit to your existing 2x4GB kit and call it a day. I can run dying light view distance %100 with the extra ram nice and smooth, ram won't give you more fps but it'll sure smooth out some games like DL, FC3/4, the usual Debbie Downers will disagree with that but hey it is what it is.

I have an fx8350@4.4ghz with 280x aka 7970ghz 3GB.

Ps, turbo core is a POS it kicks in and out jerking the game around, it's very unpleasant imho.

At least admit Turbo is great for finding a good stable overclock. Because that way it will crash less while you are experimenting since at least base clock is stable.

nothing to add here its been answered well except that i think turbo is junk as well and disable it myself

Nope I just don't like it, the concept of turbo core is great but for gaming it just reacts badly at least for me it does.

Crash just means you're in over your head, back out, rethink and don't do it again.
