AMD 8120 Throttling

post #1 of 11
Thread Starter 
Only in certain games really, like Chivalry, Diablo 3, Guild Wars 2 for some reason.
I followed the steps here as well:
http://www.overclock.net/t/1202751/amd-fx-cpu-throttling-fixes-please-sticky

However if I disable thermal throttling in my bios (It DOES fix my fps issues), my system will utterly crash after running for under 5 minutes every time, if even that. Leaving it on however causes massive CPU throttling in certain games, to a slow down of around 18 FPS.

I checked my temperatures with multiple tools, but usually the high 40C marks are the highest I've ever seen it g, even under game stress.

Tried almost everything, thinking about getting a new cooling system, overclocking isn't my real concern, just getting it to stop throttling in certain games would be great. If I was to get a new cooling fan/heatsink, are there any suggestions, or is there something else at play here? Thank you.

ASROCK N68-VS3 FX is not really design to run any FX chip. It has 2+1 phase power.

Thanks for the reply.
So you think it's the motherboard, is there a better option you think that might be more compatible?
Also I'm thinking either way if I want to move into Overclocking afterwards, the cpu can still run a little hot if I push it, so maybe I should still get a better cooler as well?

Really I am willing to make whatever changes I need to, this has gotten out of control in some games and has become increasingly more irritating, so I really do appreciate any assistance.

You need a better motherboard and CPU cooler.

asrock boards will shutdown from vrm heat as far as I know and have experience with. If you arent using all 8 cores see if you can disable a module in the bios, or if you are lucky disable 1 core per module and make a good 4 core. This will lower the power draw and should allow you to play without throttling/crashing. If neither of those is an option downclock it to 8100 specs.
I have had my asrock itx board vrm shutdown, and thats only 4 cores with a 3+1 vrm. Would do so during heavy stress tests.
Have the asrock am2+/am3+ board with the same vrm setup, and I wouldnt put more than an fx-4100/4300 on it.

The outdated and low-quality 2+1 phase power design on the AM2-era N68-VS3 FX is designed for dual core CPUs that are more than seven years old. It is not built for any quad core processors, let alone 8 cores at 125W TDP. Your only solution is to switch to a new motherboard with a larger power phase for reliable operation (I recommend a minimum of 6+2 to 8+2 phases to support a first-gen FX 8-core) or your PC will be unusable. You will either get heavy throttling in heavy tasks that will give you effectively less than 1/16 of your expected performance, or complete operational inability. It could be worse and a destructive VRM failure with damage to one or more system components, if you try to push further.

 

You need to read the "VRM & MOSFET Info" link in my sig. Look under "The importance of power phase count", "VRM system quality and design", "VRM over-current protection", and "what's good and bad".

It isn't totally unusable right now, I can max out some games like Witcher 2 or Battlefield 3 with no lag, CPU doesn't seem to be throttling too much either, even the temperatures are okay.
Still, I am already looking into more motherboard options, and I appreciate the help. Thanks you guys! smile.gif

Would the ASRock 990FX-EXTREME3 AM3+ be a better option?

For stock speed yes. For ocing yes and no. The max will between 4.0-4.5ghz on all 8 cores.

That sounds about right for my needs, but if you can think of any better alternatives I would love to hear it. Generally I am trying to stay within the $180 price range though. I'll keep looking, and post if I find anything else interesting. Thanks man.
