Hi, i just wanna ask you about the overclocking. Is overclock this cpu to 4.0ghz eliminate bottleneck in this setup ? Couse now (just in Rainbow six siege) i have sometimes 100% CPU usage and fps drops (becouse of that). I already OC a little to 3.6 without changing voltage, but still the same.

edit:
I just wanna know is it even worth to try something or i need to take something more powerfull like fx-8300 (i think about this one).
 
Solution
Since your motherboard doesn't have active VRM cooling, I wouldn't push the voltage past 0.2V or so over stock. You could go on Amazon and get those stick on copper heat sinks that actually work surprisingly well, but I wouldn't push voltage much until then. If 3.8ghz is unstable regardless of voltage, back it off to 3.7 or 3.6 and leave it there for now. In the meanwhile, look up the term "VDroop".

Bios overclock > AMD Overdrive overclock. Stability/results seem to be different every time I tried with the same settings dialed in.
HONESTLY, the 955 Deneb is a beast, and will probably surpass the performance of a 8300 in game.

You should be able to strap a decent cooler on the 955 and OC the hell out of it. Like a lot. Watch temps - the 955 Deneb is pretty legendary and takes a wicked OC - usually hitting a thermal barrier before becoming unstable.

I think that you should certainly be able to squeeze a bit more perfomance out of your 960 before upgrading.

I would highly suggest you not upgrade to an FX series chip and stick with your Deneb until it can't do it - then move to Intel.

 
The Phenom 2 with a 960 is ok and is shouldn't see a whole lot of bottleneck. 4Ghz may be a bit much but you never know I got my thuban to 3.7Ghz pretty easy. My video card is the R9 280 which is about as fast as the 960 and it runs great. the newer AMD cpu's are slow on the core so stick with the phenom until Zen.
 


4.0 and beyond should be possible with that cooler. Keep it under 90c under full load and you'll be fine. Yeah its hot but it is AMD and the Deneb is legendary. You have one of the most OCable chips ever made.

OK guys thanks. btw about my motherboard it's ASUS M4N68T-M.

I don't know how change the voltage i mean there are about 3-4 different options with voltage on my BIOS and don't know which one to change but i will ask for help maybe some of my friends ;)

Yeah i know but which one i need to change ?
I have in BIOS something like:
HT Over Voltage
CPU Over Voltage
VDDND Voltage
LoadLine Calibration
Chipset Voltage

I need to work only with CPU Over Voltage ?

Edit:
And one more question, do i need to change enable/disable some other option like Cool&Quiet or something like this ?

Is that normal that in CPU Voltage i need to just press +/- from ~1.025 to reach 1.35 (then text turn yellow) when stock voltage is 1.32 (That's what my hardware monitor shows) ?

I want to do it from BIOS but thank you for advice I set 3.8ghz and 1.35V seems stable for now. (without change voltage it was crash after 30 sec in game) now no crash and rly good temp imo. I also disable Cool & Quiet.

OCCT will be good for test btw ?

EDIT:

Even with 1.4V on 3.8ghz crash after few seconds in OCCT test :/
In games is stable but....

EDIT 2:

On 1.45V It was like 1.5minute in OCCT then crash, so better but also crap.
You think I should go higher on Voltage ? Or I need to change something in different options in BIOS or ??

3.6Ghz is stable without even changing voltage which is 1.32


EDIT:
OK guys i leave it on 3.7 with 1.375. I will just wait for next payday and buy new cpu + motherboard
Thanks again everyone for help.

Btw. Maybe someone can suggest good setup (CPU + MB) not very expensive. Something around 200-250$ ?
