It should work. Just make sure that the required RAM voltage is supported by your system. Also posting your complete system specs will help us give you more precise advice.

Nope did not work!

Mobo beeps when new PC3 -1600 is fitted.

Someone else is fitting it. According to them its a HP Desktop circa. 2009. I don't have exact mobo specs.

Theoretically it should be compatible but in reality it may not, especially if the system comes from a big OEM. A lot of them limit the compatibility of their systems in order to sell their own branded parts. The fact that it beeps is a sign that the motherboard can't even recognise that RAM. It's like there isn't any RAM installed.

Put the old RAM back and try to find a newer version of the motherboard's BIOS. If that doesn't work or you can't find a newer BIOS version, try to reset the CMOS and test one stick at a time on each motherboard RAM slot. If nothing changes either the RAM is bad or you are facing a compatibility issue (most probable) that I'm afraid can't be fixed.
