Overclocking FX8320

[harrynowl]

Are you using JUST the multiplier to get your 4.2GHz (200 x 21) or are you adjusting the Core Clock (aka Base Clock or FSB) as well?

1.35V Core Voltage is perfectly fine, but 67*C is a little on the high side.

 

A Cooler Master Hyper 121 EVO should be absolutely capable of handling a FX-8320 at 4.2GHz and a mere 1.35V.

Make sure your CPU cooler is mounted correctly and securely, and the thermal paste is not "over spilling" onto the edge.

Too much OR too little thermal paste = bad

Is this socket temp or actual core temperature? The socket temp on my AM3+ Board gets to 65c at 1.2V on my FX8320 after a long prime so it's best to make sure.

Yeah, it's socket. Core goes to to 52.its all within safe temps. Asus AI suite yells at me though when it gets to 65 (socket). My motherboard I think might be the cause, I'm not sure.

I'm comfortable running 62 core 70-75 socket (it really is unavoidable past stock voltage). Your mileage may vary.

That is very hot for the voltage. Stock voltage should be 1.325-1.375 depending on CPU.  Also it failing to 1.2 volts tells me the LLC may not be set correctly or high enough that could cause you to increase Vcore to compensate for the Vdroop. I would raise LLC and drop the Vcore to lower temps and help stability.

 

So running prime95 at small FFTs my cpu socket goes up to 62+ degrees but with the AMD stability test it's only at 54 degrees.

 

Can you post a screen shot of CPU-Z and any other monitoring software you are using after a 10 minute Prime95 run? Take the screen shot while it is still running.

I changed my q-fan profile to turbo... helped by like 1-2 degrees lol. I went way over budget upgrading my PC recently but I might fork over another $120 or so for a new motherboard, probably the m5a99x evo 2.0. Seems like a much better board

[Prokart2000]

when did they bin them?

[Nomelas]

Brand new cpu if that's what you mean.

[Prokart2000]

no when did amd start to bin the cpus (I have 1 just wanted to know then I know if it could be effected)

[Nomelas]

I'm not sure...

Temps are very good, you're sitting at 47c on the core, that's perfectly fine for 4.1Ghz.

You should be able to manage 4.3Ghz @ 1.35v & stay within safe thermal limits, then tweak your overclock further and go higher.

 

[Prokart2000]

how is your core at 1.284 volts my amd turbo gets 1.4 plus

It goes down when I'm running prime95, kinda annoying. I turned off turbo.

[Prokart2000]

oh ok weird is it manually set

[Nomelas]

Not currently, that's at stock. All I did was disable all power saving things and turbo. Then set the multiplier to 20.5 and fixed the ram settings.

[Prokart2000]

try manual maybe? not really sure

Well it's stable so you'd probably get away without setting LLC to high/ultra. I wouldn't entirely trust that vcore reading.

So the board goes from 1.320 volts down to 1.272 volts under load? That 0.048 drop in voltage can hurt an OC and stability,

 

Raise your CPU LLC up one without touching voltage and see how much vdroop you get.

All I have for LLC options is auto, enabled and disabled sadly. It's an old board, the non R2.0

Was the picture taken with Auto? Try setting it to Enabled and look what the voltage is under load.

that's set to auto, though auto and disabled are basically the same. When enabled the voltage shoots up to 1.4 under load, and that's too hot for my system.

Try to make your own custom p-states, just like I did. Use AmdMsrTweaker.

Those are some good temps. Btw how would that help me? (need more info)

Set the vcore to default, LLC to lowest and disable turbo.

download this file:

http://www8.zippyshare.com/v/9940570/file.html

unrar and and run the AmdMsrTweaker.bat file.

If your system freeze, the idle voltage ( for p5 and p6 states) is too low. I'm sure you will have to edit that bat file because of silicon lottery. Lock the p-states with catayst and run occt for each p-state. Instable? Edit-save-run unlock and lock back pstate with catalyst.

I even reinstalled windows and those pstates remained. This tool is amazing.

Hope it helps...

seems dangerous.... will this mess up my system?
