Hello there.
I'm trying to OC my card but getting a lot of crash screen (like TV with no signal,kind of this http://en.clipdealer.com/preview/image/000/049/377/prev... )
I did the OC from 955 / 1400 to 1100 / 1600 without increasing the voltage because I can't move the voltage slider in MSI After Burner, and got crash every time I run Valley Benchmark. Then I found out for Asus GPU tweak, I increased the voltage to the max allowed (1225 mV) and I'm still getting those crashes :S I have seen people going more with this card but I can't do even this small OC, please help me! :S
My other setup:
FX 6300 (OC to 4.0 Ghz / Turbo 4.3 Ghz)
Gigabyte GA-970A-DS3P
4 GB RAM (upgrading soon)
MSI R9 270 Gaming 2 GB
600W PSU
What should I do to get 1100/1600 OC to my card or atleast what is max OC for my card? What did I do wrong ? :S

For.my advice use to.install the msi after burner beta and unlock ur graphichis potentially. Votage slider.ander other limits use to chej that ur gpu is pripey fitted on your mother board and having good airflow use to try with 1000mhz try increasung and incrising 20-40mhz and again try uo.bench mark when u crash just slide ur slider Lil bit and.again bench if again crash pull it that much again again test I m sure it will help u

I tried tweaking a little bit and get it working i think, we'll se
I set the voltage to 1200 mV , GPU clock to 1100 and memory clock to 1565 mhz and also the power limit to 120%
I tested like for an hour or 30 min (idk) in the Valley and no crash
but i'm a little confused :S When I set the Memory 25 mhz higher and the voltage was in max it crashed , now with 25 mhz slower memory and with less voltage it works
dafuq ? Someone explain this to me ?
the cards just have their limits, you cant clock every certain thing so high, its generally optimized as best as it can be while still being in safe limits, the extra 25Mhz is just more than the card can handle, simply put.

A. Uninstall MSI and try Asus gputweak. The power limit has always worked for me on gpu tweak and I personally don't like msi afterburner as much.
B. You gotta b careful with voltage and power limits. You can easily break your card and you probably would going for such a high OC
C. Its just too much of an OC don't expect more than 250 MHz out of the core clock and memory clock maybe 200 mhz as well though memory overclocking has never been stable with my HD 7870, so I just bump up the core clock for a little performance boost.
Any massive GPU overclock would probably require flahsing a custom bios and is vey hairy. Just stick to a small OC and go up in increments of 25 MHz . up the core and the memory seperatley as to find stability for each (isolating variables).
