Hi all,
I've started being curious about overall system performance. The specs are:

What made me worried are GeekBench benchmark reports which say that my RAM is running at 333 MHz instead of 667 MHz. I've also set up a RAM-disk to verify the speeds and these are looking also quite bad. Usually NVME drives get better read speeds than my RAM memory.

Another thing which bugs me is system load while watching youtube videos. This is consuming about 120% of the overall system performance while watching a 720p video in a window- even though I've got mac-flashed GTX 680, which should support metal and h264.

Do you have any ideas if it is a normal, or something is indeed wrong?
Please find benchmarks below.

SSD speed test which im going to change to NVME drive (BootRom already flashed).

Videoproc saying that there is no hardware encoding for h.264.

It's double data rate memory. The clock rate is 333Mhz but the effective speed is 667Mhz. The actual clock rate of DDR memory is half the effective performance. It's just that Geekbench reports the clock rate without doubling it for the data rate.
