AMD A10-6800k throttling?

[mstang67]

Hello everyone,

I've spent hours and hours trying to get all this sorted out and have finally decided to make a post, try and get more help. First I'll start with my setup:

AMD A10 6800k Richland
CORSAIR Hydro Series H100i
BIOSTAR Hi-Fi A85W FM2 AMD
Apevia Iceberg ATX-IB680W-BL 680W power supply
G.SKILL Ripjaws X Series 8GB (2 x 4GB) DDR3 1600
ASUS DirectCU II R9280-DC2T-3GD5
WD Blue 1TB WD10EZEX 7200 RPM
LG GH24NS95 Super Multi DVD
DIYPC Skyline 07-G Black/Green Full Tower

I just received the water cooler last week and WOW how outstanding it is compared to the stock fan. Of course, being an FSX user I want to push this CPU for a chance at higher frames and performance. Everything is good....as long as I only go to 4500 MHz. Runs stable, and I gain about 5 frames, making it considerably more playable. 4600 MHZ, still have yet to find a stable voltage for that. 4700 MHz and up, I can get it to run, but here is where the trouble is. 2 CPU cores stay at the overclocked condition, but 2 go down to 2000 MHz (soon as a load is put on). This is the case from 4700 MHz to 5200 MHz. Performance does decrease in-game, so I know the numbers aren't a glitch.

I've never messed with overclocking before so forgive my noob-ness but am I right this is referred to as throttling? I have no idea what to do from here. Any ideas what this could be?

In addition, my RAM is only operating at 800 MHz, instead of the 1600 MHz it should be at. How in the world do I change that???
