Well I have 6 x 280x , i modded the timings of the ram with tahititiming mod! It was ok , but after 10 min of mining one card started too fail , I flashed the original bios back to all cards , but one this card remain to make trouble , 0hashrate and windows crashing! When i removed it everything was ok! Now with the original bios it works OK and have enter windows but only if the driver is not installed. When i install the driver , the screen gets all in blue white lines and pc crashes. Now i flashed custom bios with 500mhz core and 150mhz ram. It is working perfectly even hashes with no errors and i can rum 3d benchmarks! When i up the core to 900 with msi afterburn everything is ok , but if i up the ram more than 420mhz it starts to give artifacts and the nice carpet screen! So my question is what could be wrong ? Now it is hashing with claymore miner at core 800(real, default is 1070) and ram 400mhz(reall clock not +400, default is 1500) at the speed of 26sol/s and have no issue , i run Video Memory stress Test v1.7 and there no errors? What could be wrong , ram or gpu is failing?
