A75M no video at 1866 issue

[Neuromancer]

Thought this was an AsRock issue but after grabbing a Biostar board it also appears not to work

A6-3650 (purchased NIB off eBay)
2x2GB Patriot Sector5 2000 9-11-9 (have tried others)
350W PSU
and the biostar motherboard

System runs fine at stock, but every time I try and set 1866 MHz the system reboots and powers off the monitor.

Does vgpu need to be adjusted when using faster memory? or is their some other setting I am missing

Not finding anything on this on forums, all of them just state how strong the IMC. Bad CPU maybe?

When I reviewed teh A75 biostar, the BIOS was not evne working for 1866, so I can be of no help but to give you bump.
