Crashing Problems with New Sapphire Radeon R9 270X Please Help!

[Osiris1975]

Dear Tom's Hardware Experts,

I'm pulling my hair out trying to fix a problem I'm having. I recently decided to upgrade my GPU to the Sapphire Dual-X R9 270x . Once installed, it played okay for a bit but then proceeded to crash during all my video games, but most frequently with Battlefield 4. I swapped in my old video card and the problems went away, so I figured I just got a bad card. To be honest, I also replaced my motherboard because I think the old one died shortly after I put in the old card again. I returned it in exchange for another of the same model. Bam, 3 crashes playing BF4 within an hour of installing the new card.

If you look at the links below, at the Amazon link for the R9, I have already tried the solutions posted in the review thread. The only thing I haven't tried is replacing the PSU, so that might be the next step, but I thought that my PSU met the min requirements for this card. Any and all help is greatly appreciated before I end up spending more money on this problem or getting a new PSU without knowing if that is really the problem!

Some links to my hardware in case that helps:

did you uninstall the drivers for the old card, and install the drivers for the new card? and i read the resolution on the amazon review page and it looks like they downclocked the card because it was causing it to crash. did you do that also?

if you did all that.....prolly get rid of the card and get a different one maybe

also a beefier power supply would be in order, i'd go for a 650 watt 80 plus bronze certified power supply if you go that route. new power supply first then try a different card manufacturer like the one i linked above

Hello. Don't know if you solved your problem allready, but for me, the solution was too downgrade the speed from 1090 Mhz to the 1000Mhz (which is the base for the card).
