I tried in on Z400 6 DIMs, with almost any combination, and all gives me boot rel light blinking with 5 beeps. Talked to technician and he said the these are not compatible and false advertisement. tried to call "A-Tech" it says all busy and took my number to call me back, and that never happened. I have wasted my time for at least 2 days on this. Returning it to our admin who got this for me.
