Overclocking Cpu and gpu

I have a amd fx-8350 with base clock of 4.0MHz, black editon and a sapphire radeon hd 7950 vapor-x. I was wondering if it is efficient to use both the integrated graphics along with the dedicated and if it is possible to do it. I know some amd processors allow that but idk exactly. I am mainly playing: skyrim, FC3, some simulator games and maybe some other high end main stream games.

(OUTDATED) THIS PART IS SOLVED! SCROLL DOWN TO THE LAST FEW AND READ!

there is no integrated graphics on an fx8350; and no integrated graphics anywhere that will pair with a 7950.

overclock that cpu a bit, it will give you a nice boost in skyrim.

I thought most cpus have integrated graphics or maybe its just because I am used to laptops lol

how do i OC? I have a non stock cpu fan and have been looking into doing it.

pretty straight forward, load into your bios. go to your cpu settings (likely under an advanced tab of some sort). increase the cpu multiplier by +0.5. save and exit. see if you can load into windows. If you can reset the machine, go into your bios and bump the multiplier by another +0.5. keep doing that till it won't load into windows anymore (or doesn't POST, usually it will fail to load into windows first, but if it fails to POST don't worry, after 3 failures it will reset your bios back to stock settings).

Then you go into your bios, and change the vcore from auto to manual, and set it up +0.0125V from stock (1.3500V or 1.3385V, don't recall off the top of my head which is stock, i think stock is 1.3385V). Save, exit and see if windows will load. If it doesn't, bump your vcore another 0.0125V. understand it's the vcore bumps that increase the heat of your cpu, NOT the multiplier bumps, so this is the step that we need to be careful at.

When you're able to load into windows, jump online, download hwmonitor and prime95. Check out the cpu and motherboard temps. the safe max operating temps of a FX 8350 is somewhere between 62C - 68C... i have seen 8350s that will run at 70C, but i wouldn't recommend it as i suspect running it that hot will shorten it's life quite drastically. Understand, FX cpus don't always report their temps accurately, you can eyeball the numbers in hwmonitor. the cpu temps at idle SHOULD be around 5C-10C hotter then the hottest part on the motherboard. As long as the cpu at rest is reporting temps like that you probably can trust it.

assuming temps are alright (no more then 10C over ambient room temp while idling) run prime95. i like blend cause it's a max heat test, but really it probably doesn't matter which test you run. let it run through 2 or 3 passes. assuming no cores fail, the program doesn't crash back to desktop, or the computer doesn't just flat out reset, while your temps stay nice and cool, your cpu is properly overclocked and ready to be pushed higher. If any of those crashes happen and temps don't spike up over 65C, then you have to bump the vcore another 0.0125V, and try again.

Once you have stabilized at this clock, you can chose to either push it higher or stop there. Generally if i'm getting temps in the 40s or 50s while running prime i'll keep overclocking it, like we just did. pushing the multiplier till it won't load into windows anymore. If i'm showing low 60s in prime, i'll bump the multiplier 0.5 more and see if i can run prime without a vcore bump. assuming i can i'll bump the multiplier again, and rinse repeat.

Basically overclocking is about a race between multiplier, vcore and temps. as the multiplier goes up, you'll eventually need to add vcore which will raise temps. you're limited by your temps. so it's a race sorta.

When you reach a point you're comfortable with, when the temps in prime95 are hot but not too hot, and the cpu speed is high enough to make you happy, run prime95 for a longer burn. a nice 4-12hours (i like to go with 8 hours, some people will tell you 24, generally i think most major problems will show up in an hour, but the minor stuff will come out by hour 4-8 imho). Assuming it runs flawlessly and temps are good you have a rock solid overclock and are ready to go.

"62F - 68F"

Do you mean 62C -68C?

Is core temp reliable?

Also do you know how to use EZ overclock on my gpu? its a sapphire vapor-x 7950 3gbs

yeah, i meant C

don't bother with overclocking the gpu till you squeeze every last drop out of the cpu. your games are cpu intensive so boosting that will give you better bang for the buck so to speak.

coretemp is a little more reliable then hwmonitor, and both programs are only as reliable as the cpu... i like coretemp for monitoring cpu temps when i know they're being reported accurately by the cpu. i like hwmonitor for figuring out if my cpu temps are being reported accurately, and for keeping an eye on case airflow when working with a new case

Should I use ez OC and get cooler temps and trade out 0.1MHz of clock speed?
