How to downclock Radeon R9 270

[salearsic994]

Hi,

I need help.
I bought a Radeon R9 270 graphics card. Everything worked fine until I started playing games. Each game one after another crashed or caused freezing. After hours of research and not finding a solution I was ready to return it until I realized what is causing a problem. GPUs memory runs on 1400MHz but my RAM on 1333MHz. When I downclock it to 1200MHz everything is working perfectly on high resolution.

Now, what is the problem? This is only effective for games. Not for other applications. Or when I use the other screen (I have a dual monitor) for checking mail, for example, GPU memory goes back to 1400MHz and freeze entire system.

Is there a way to downclock it permanently for the entire system, not just games, apps etc..?

PC:
MB: Dell Optiplex 3010
CPU: I5 - 3570
GPU: Radeon R9 270
RAM: 2x4gb ddr3 1333MHz
PSU: 500W Chieftec

Thanks

MSI Afterburner > Adjust clock > Apply overclocking at startup

Also, GPUs should work out of the box. It might be faulty or it might have compatibility issues. If you had a GPU before this, use DDU to clear drivers.

The same thing happens. Sometimes out of nothing memory clock jumps to 1400 and freeze everything.

Use DDU then reinstall AMD drivers. Try different versions too. Adrenalin for example.

Underclock to the lowest possible, test. If it happens again, could be buggy GPU BIOS. Check the BIOS version with GPU-Z.

Just a thought to keep in mind..your GPU memory speed and system RAM do not need to run at close speeds to be stable, rhey are independent of one another. It's quite possible that your power supply can't comfortably provide the juice the graphic card needs when it is running at full speed. It would be nicr to try a good quality PSU in its place to rule that out.

I second that. That is OP PSU https://www.newegg.com/Product/Product.aspx?Item=N82E16817202014

It is the borderline for power requirements and by quality is located in the bottom of the list....

You need some quality PSU starting with https://www.amazon.com/dp/B01B72W0A2/?tag=tomshardware_forum_vgl-20 no less than.

Dat classic shiny metallic PSU. and I thought it was one of the newer ones. Even if's not the PSU causing these problems, I would upgrade it for the sake of my other components. Good PSUs last a long time. It's a worthy investment.

R9 270 has 75+75W consumption, i5 up to 80W, Motherboard RAM, HDD and fans let me say up to 100W MAX. So PSU is not a problem.

I read too many times on the forums PSU is the problem or updates your driver 🙁

The only two solutions I could make it work like a charm so far are:
- Downclock with MSI Afterburner, and during gaming not to use the second monitor for browsing or playing any kind of videos since those are the reason GPUs memory clock goes above the limit in Afterburner
- Purchase 1600MHz RAM, since testing with borrowed ones on 1600MHz clock works fine.

Thank you all for help

We are not worried about the power supply being small, we are worried about it the quality of the power supplied or how it will last after hours of intense gaming.

It's cheating too, instead of a single 500W 12v. it's 212+212=424W. If you decide to upgrade again, change the PSU too. Don't risk losing everything. Too many people frying PSU with power outages/overheating/...

Purchase 1600MHz RAM, since testing with borrowed ones on 1600MHz clock works fine.

I'm using 1866MHz RAM with 4400 GPU Memory clock. No problems.

Could it be that your 1333MHz RAMs were faulty and could not handle the extra load demanded by R9 270?

But kudos for getting everything working.
