You can run ddr3 2400 on it check prices though some of it might be £50 extra

I got some corsair several years ago from the warehouse bin at a knock down price and it's been great running at 1200mhz only the cpu also gets a bit warmer when overclocking too so you need a super great cooler for it and don't forget a quality 850w psu. At least the sabertooth runs it at ddr3 2400.
But whatever you do by the time you spent the money for the right gear you could probably have bought a ryzen that will easily eclipse an overclocked 8350.
Starting with the board isn't the best strategy at this point since the fx is quite obsolete now. There will be way more value for money that is cpu processing power with a ryzen, though there is a bit of fuss picking the right board and memory for it at the moment, probably 'til the summer release of the next ryzen.
If you flog the gigabyte for $50-60 on ebay that will probably make up the difference with a ryzen build if since you will need a higher end cooler and psu for the 8350.
