I wanted to go further with 6 cores. Cooling is not a problem but ever since I shifted to liquid cooling temps have gone down a huge deal but my overclocking had become limited on this 4+1 vrm phase mobo as now the rad covers my vrms frown.gif

How is your overclocking on the 6300?

i have the h80i on my 8320, i can reach 4.7 stable with a good thermal margin, i can hit 5.0 or more without a load on my computer, once i get better cooling you can push the chip further. its the luck of the cpu lotto, you could get a chip that is amazing and takes less volatge to get to overclock, or you could get one that is horrible for overclocking. i would say go with the 8320 just because ive had so much luck with it, i would just get a cooler that you can fit away from the vrm so they can stay nice and cool while overclocking. good luck with your choice! biggrin.gif

How is your overclocking on the 6300?
4.7/4.8 all day. Got to 5+ but no testing yet. Well 2 or 3 minutes of OCCT, no overheat, but random core failures...so far.

Here's a bench I have at 5Ghz.


What vcore you use for 4.8Ghz?

Depends a lot on the load

Depending on amount of threads and emphasis on them, you could have this situation for example:

Load A runs faster on CPU 1

Load B runs faster on CPU 2

Load C runs about equally as well on both


Also, you have an interesting situation with Bulldozer arch and the improved versions - Every module shares resources on two threads.

That creates a situation where you would think, traditionally - an 8 core CPU @4ghz won't beat a 6-core CPU @4ghz if you're only using four threads!

However that's not true for Bulldozer/Piledriver/Steamroller etc. On an fx6300, you have 3 modules. If you have 3 threads, one goes to each module. If you get a fourth thread, two of them have to run on the same module and share resources, which can give no slowdown (optimally) or a lot of slowdown (lots of conflict with resources)

On an fx8320 at the same clock speed, that fourth thread would just jump on the fourth module, and it can't be slowed down by having to share anything.

That does not come into practice much, but it's to show that you can get benefit from an fx8320 over a 6300, even if you're only using 4 threads for that particular work

The i7-3770K will compile Linux Kernel version 3.1 in 91 seconds.
The i7-4770K (the one everyone claims doesn't make any difference, and is all iGPU and power related), does it in 74 seconds blushsmiley.gif
And it will only cost you $140 more than the FX-8350 does to get that extra 11 seconds...

There is only a $10-20 difference between the FX 6350 and FX 8320. Why would anyone get the 6 core when you can have an 8 core for only a few bucks more?

If you're planning on keeping the system for a while, the 8 core is the way to go.

In the UK, it's £80 vs £104 now, but i've seen bigger gaps before. It's a bit harder on cooling and mobo too, as well as like described, the fx-6's tend to clock higher/easier. I can see somebody wanting one in a cheap system if they're not doing primarily heavily threaded work (that would run 25-30% faster on 8320 even with a bit less clock speed) - as intel has no competitor to it thumb.gif
