AMD 8370 OC Questions!

Hello everyone!

I just want to OC my FX 8370 to 4.70 GHz. However, i have some doubts and questions:

1. Do i have to turn off all the power saving feature? Example cool n quiet etc.

2.Do i have to set the windows power settings to high performance all the time?

3. What is the best Vcore for that speed?

Thanks in advance! 🙄
 
I'm using a Cooler Master V8 GTS + 8 120 mm chassis fans and 8 GB Gskill Sniper @ 1866.

The motherboard is a Asrock Fatality 970 Performance
 
turn off CnQ for now. I haven't turned it back on. it costs you about 15-20w at idle with full frequency on the CPU. Right now I'm at 4.3ghz 24/7. Enabling C1e made a HUGE HUGE HUGE difference to idle AND load temps and NO difference to stability when overclocking so I would leave it on. and I do mean huge

you're going to need pretty high volts. from 4.3ghz to 4.5ghz on my chip requires another 0.1v and then some. was totally not worth it. after 4ghz this chip was pretty fast. then i ran windows update and it became a lot slower. not sure what to do now but I went with the updates because of issues with installing IE11 which I wanted. best would have been to leave off the updates. was much faster
 
also at those speeds and voltages you're going to hit the thermal throttling on the VRMs. I have 8+2 VRMs and still throttled even at 4.3ghz after 3-5 minutes of torture test. Not CPU throttling issue, although it did throttle the CPU, the source was the overheating VRMs. they don't make vrm sinks with as much surface area (more expensive) as they used to so I bought a PWM splitter for $20 and got a small 65mm fan and shoe-goo'd it to the top of the VRM sink. It's quiet, only gets up to the speed my CPU fan does (45%), and solved all my overheating VRM issues. going past 4.3ghz would likely require much higher speeds and releases a lot more heat and makes the summer AC bill a good 20% higher so haven't bothered with it
 
This MB has a functionality that allow to overclock the CPU to its higher frequency state with all cores by selecting the option ‘X-Boost’ when booting, for a FX8370 this will result to 4.3 with all cores...

Otherwise Hardware.fr got their 8370E working stable at 4.5 with these settings :

VID 1.275V

LLC Extreme

Voltage in CPU Z 1.32V

The voltage displayed by CPUZ is the real value at full load and shouldnt be exceeded, TDP should still be about 125W with mlultithreaded heavy loadings like Cinebench, dont try with Prime 95 at this level as TDP would be 160W.
