Hello,

 

My side project right now is an HP Z400 workstation, with a Xeon W3503, and a Quadro FX1800. I've installed a clean 320GB HDD, 3x2GB in the three channels, power supply, front panel stuff, and all that. Whenever I try to boot on the system, the red light flashes on the power indicator, and the PC speaker beeps incessantly. What have I done wrong?

Do the basics. Reseat RAM and run it with different sticks, reseat GPU, move GPU around (if there's more than one x16 slot), reseat the CPU...

 

Also give this a lookover. It might shine some light on the issue, but I'm not 100% sure on that. http://h30434.www3.hp.com/t5/Business-PCs-Workstations-and-Point-of-Sale-Systems/Z400-fails-to-boot-fans-running-full-blast/td-p/5048656

Thanks, before i posted, i reseated processor, GPU, RAM, etc.

The article seems to point to a motherboard issue, and fortunately i have a second system, nearly identical except for not having a 2nd cooler.

Does that motherboard support only 3 sticks? Can remember an issue where it had to be 1 stick, 2 sticks and 4 sticks. Not 3... Might be your issue. Try it with one stick of memory first, and then upscale.

Yeah, it's a 6 slot, 3 channel setup, so the default would be 1/channel hence 3, but i have tried different RAM combos.
