I wanted to blame my MR816csx for the CPU spikes, clicks and general lack of performance from my core 7 CPU.
However, today I ran the latency tool and discovered, discovered after disabling everything then reenabling one at a time, that my bleeding graphics card was the sole culprit! I changed it now my MR 816 works a dream and the CPU performance is also lighting fast.
So, I can’t rate the latency tool highly enough. Download it and use that before dismissing it as needing Texas instrument chipset card. Mine works just fine on the motherboard FireWire which is not TI.
PM me if you are having trouble I may be able to help.
