r7 250 overclocking thread

[corcorand82]

What do you think? Took me all morning but I got it running at a stable 1200 MhZ!

Whats the highest OC you have gotten on your 250?

Also, just for reference


CPU: AMD FX 6300 @ 3.6GhZ
Ram: Crucial Balistix sport 8gb cl9 @1600
MOBO: gigabyte GA-8lmt-sp2 rev 2.1
PSU: EVGA 600 Watt
Benchmarks: 3dMark firestrike and Furmark
I used CATALYST CONTROL CENTER to overclock the card. It makes it quite easy to ramp up the fans all the way to prevent overheating.

Cool, you up the voltage Im guessing?
Most r7 250's Ive seen get up to about 1100mhz, so your overclock is very good.

Yeah. I used catalyst and upped the fan speed to 100% (to prevent overheating), and upped the power to 20% (above stock).
I ran 3dmark at 1200mhz and had some particle errors (not to mention the GPU was running at some 80c). I also had some lines appeared randomly on "fire strike". I was only able to get a stable OC at around 1170mhz, but was able to get it up to 1200 just to take pictures.
I will try to get it higher in the future (possibly 1300+) but for now I will focus on getting a stable 1200.

You will need to increase the core voltage to get it to 1200mhz stable, beware this generates much more heat and can damage your card.

I have the voltage set as high as it can go xD

The 20% power allows your card to use 20% more wattage and is not the core voltage.

I used OC guru to up the voltage and got it running 3Dmark Firestrike with a score of 2827. Originally the computer had a score of 1995..Quite the performance boost!

Considering this is a mid/low range card, I was able to get some reletively high clock rates on the sucker. If I tweak it enough I may be able to break 3000 points.
To achieve this score of 2827, I had to overclock my CPU to 4.2ghz during the test.
