Safe overclock for FX-8320

post #1 of 25
Thread Starter 
Hi guys

This will be my first time overclocking, so please bear with me.

What I wanted to know is, how far can I bump the multiplier on my FX-8320 without playing with the voltages AND without greatly affecting temps? If you could give me an approximate temp increase of each bump, that would be great. I don't necessarily need the performance, I'm just seeing how much performance I can get for "free".

Other info:

Cooler: Cooler Master Hyper 212 Evo
Motherboard : Asus M5A97 Evo R2.0

It doesn't work that way. All CPUs are different. You just have to start changing the mltiplier and see what you get. 4.5 should be easy,

4.5 on an 8320 without voltage changes? Isn't a whole ghz pushing it too far?
post #4 of 25
Not necessarily. It it is possible to hit that without temp issues. I was able to hit 4.5 comfortably without changing any voltages but I'm also liquid cooling so my temps didn't change much. Not sure how they'll do on air. I sit idly at about 32-36*C and under load it only goes up to about 40-45*C. I also have the Asus M5A99FX Pro so my board is pretty similar to the OP's so he should be able to see something similar very easily. I hit it by changing my multiplier to 21.5 and having a speed of 210.

4-4.2GHz is maybe possible if you are very lucky, but without changing voltage i think 3.9-4GHz is more reallistic.

And he said wich hardware and cooler has, i don't understand why you're talking about RL's, saying him that 4.5GHz (which is really high with that processor) is possible without changing voltage, etc...

Unless his mobo gives at stock a very high VCore, i think you're wrong, and with a simple Hyper 212 EVO go to 4.5GHz on a FX-8320 without having problems with temperatures, i think it isn't possible.

P.S.: sorry for my bad english if i made any mistake writing...

Not entirely true. The major variable for his cooling is the fans. The 212 is actually a very solid cooler and if he upgraded the stock fan and got a push/pull config it keeps temps very low. As billbartuska said though, it does depend on the CPU. Some overclock better than others. I felt that mine was very easy to OC with but maybe I just got lucky. At a minimum he could hit 4. But if his temps stay good I don't see why he couldn't hit 4.5. I didn't have to touch my voltages until I was getting to 4.7.

ya I agree.,,,i couldn't leave my 6300 at 4.5ghz because of heat,,,i was getting 65.c+ coretemps,,that was with a push/pull 212 evo,,,

You're wrong...

I own a Hyper 212 EVO precisely, and i tested it a time ago replacing original fan with other fans in push-pull, and far better than original one fan, and temps only went down about 2ºC less...

I own a Scythe Mugen 2 rev. B too, and with this cooler replacying original fan with others, in single or in push-pull, temps went down several ºC, but Hyper 212 EVO in push-pull and with better fans than original doesn't benefit much...

I'm not saying I'm right, I'm just sharing my experiences. It's all I can do. When I was running mine on my unlocked and OC'ed 960T I saw about 4*C drop on my temps, which isn't much but every little bit helps. I'm not saying he's going to see a 15*C drop in temps from it, but 4*C is definitely not nothing. Now I haven't run my 8320 on air so I don't know what the temps are like at stock, but apparently trailer park boy also had the issue with his getting hot so I guess it may not be possible on air. The only way we'll really know is for the OP to try it smile.gif

On that note, what temp recorder do you suggest? Core temp gives me low to mid 30s while playing metro 2033 which is suspiciously low (room temp ~20C)
