Question about overclocking the AMD FX 8150

post #1 of 12
Thread Starter 
Build:

AMD FX 8150 8 Core 3.6ghz
GIGABYTE GA-970A-UD3 motherboard
8gb G-SKill Sniper 1866 ram
Thermax Eclipse 2 Heatsink
Coolermaster 750W PSU
AMD 6700 series GPU


Question is everytime i get to around 4.2ghz it becomes unstable. Like the computer can just be idling and just reboot out of no where. At 4.1ghz its pretty much fine. Whats my bottleneck or what do I need to do to get to at least 4.5ghz cause i know this is capable of it by looking at youtube videos?

1) Max CPU voltage is 1.55v.
2) Max CPU Core Temp is 62c.
Your bottleneck is HDD and yes a HDD is the biggest Bottleneck in all system.

No. Bottlenecking mean the component that slow down a rig.
More then likely it is an heat issue like CPU or VRM overheating.

EDIT
That gigabyte has a 4+1 Power phase, so not really good for ocing a 8150 on.

Sorry Gigabyte made 2 version of that Mobo.
You going to need about CPU voltage 1.4-1.45v for 4.5ghz and keep your temp under 62c.

OK so here is what Ive came to so far.

4.5ghz @ 1.45v doesnt boot

4.4ghz@ 1.5v boots but idles at 32 degrees celcius and as soon as i start prime 95 goes over 62 and stop immediately

4.1ghz @ 1.46v is the stablest where i run prime 95 and dont get past 55 degress celcius so im going to need a water cooled system or something better to get beyond or where i want.

I have my 8150 at 4.5ghz, core volts is at 1.425. My idle temps are in the high 30s and running prime 95 for 4 hours with no errors and my temp maxed at 77. No stability problems at all.

You talk like that's no problem. It is an problem. That is way too high! Your not going to have to worry about CPU temps for too long at that rate.
