199.6 x 14 = 3.794.4GHz ~ 3.8GHz
199.6 x 14=2787.4
Anyway, why wont the CPU run at 3.8?
A few years ago I bought a Compaq ML110 G2 motherboard because the owner had a similar problem. His new 3.6 GHz CPU would only run at 2.8 GHz which happens to be the default speed when a CPU is not recognized. I'm currently using it with a 3.2 GHz CPU that's officially supported. The maximum is 3.4 GHz and that's probably the same with your system.
