R7 260X Artifacts with 1Mhz Memory Overclock

Hello,

I recently purchased two Sapphire Radeon R7 260x OC GPUs and have them running in Crossfire. I'm having two issues with them; one being that the default clocks aren't running at the advertised rating, (1150/1650) and if I attempt to OC the memory by even 1Mhz I get artifacts.

Even with the Core Voltage set to 100Mv and Power Limit set to +20% the artifacts are still present. I can OC the Core Clock pretty well, but taking the Memory clock from stock 1500Mhz to 1501Mhz causes artifacts both in game and while browsing the desktop. I have tried higher Memory clocks, but this only worsens the artifacts.

I have the latest driver installed and I have flashed the BIOS to the newest version. I'm using MSI Afterburner to overclock. I know not all cards are created equal and some will OC better than others, but I have seen numerous guides/threads with people reaching 1650-1800Mhz Memory clock. Are my cards this bad, or does it related to them being in Crossfire?

    Do not OC the GPU's RAM. Also, it doesn't matter what other people do, Silicon Lottery is something that you will hear often.

    Is there any particular reason why this card's memory shouldn't/ can't be overclocked? I'm not aiming for other's clocks; I'm trying to find what mine is capable of and I've never had a GPU that would begin producing artifacts at even a 1Mhz OC.

    My laptop's GTX 970m artifacts at about 16MHz OCed. You have a problem with what I think might be your GPU's graphics BIOS. It isn't fit for overclocking.
