Overclocked graphics card keeps crashing

[Need-a-new-cpu]

Hi all. I have the amd sapphire R9 270x 4gb and I have tried to overclock it to gain a few more fps in my games but even overclocking the slightest bit my gpu crashes when playing games I tried increasing the power limit by +1 then +5 but it keeps crashing.

I have used msi afterburner and then amd trixx but it happens with both.

All help will be greatly appreciated thanks in advance.

Gpu and Cpu are like the lotto some will over clock a lot some wont your card may already be at its limit in the first place other then pulling the heatsink and fan off and putting new thermal paste a good brand on you wont get a lot out of it forward.
