DDR stands for double data rate so likely it is 400 x 2 for 800mhz. Your RAM is running fine.
My DDR3 1600 shows as 800 in CPU-Z.
Thank you for your reply I spent some time to get timings on ram and used cpu-z to locate CAS# Latency RAS to CAS# ECT.
I input the correct ratings into bios and now my pc seem to run a little faster
again thanks for your time
