Mine is worst. CB 20 score only 1783, with 2400G, 2x8GB CL16 2933 Mhz RAM & Noctua cooler (no LNA).Maybe...
I took off the Noctua, cleaned the cooler and CPU with rubbing alcohol, applied NT-H1 thermal paste, connected a second fan to the A300 and left the case open to maximize air flow, and rest windows. I was able to get a CBr20 score of 1910. Boost clocks where still power deliver limited. Part way through the benchmark it still throttle but it did so later in the run and stayed a few MHZ higher after throttling. Power delivery was the same, throttling just happened later in the run.
So it's an improvement. With the 2400G my score was constantly in the 1860's - 1880's and I couldn't get anything higher. Was bothering me I couldn't get over 1900 with the 3400G. I did several runs in a row and it was 1895 (first run), 1910, 1910, 1910, 1910...
3D Marks Night raid - 13293
3D Marks Sky Diver - 12741
Not much of a change which makes sense since the iGPU was pegged at 1400 MHZ
so... yeah... really hoping for a BIOS update. The 2400G with BIOS 3.40 would stay in the 80's and maintain it's OC boost as long as the temps held there. The 3400G with BIOS 3.50 will start throttling at 75C and keep running at stock and 65C :/
