Hello. I recently had a mother board go dead on me. I purchased the exact same motherboard I had. the new board is same model, brand and all that, but the overclocking on it is considerably worse for some reason. Any suggestions as to why this might be? as an example my rig is fx 4100 quad core radeon 6670 gpu kingston hyperx 1866 8 gigs ram ocz vertex 3 ssd 500 gb western digital asrock 990fx extreme3 corsair 600w gs600 The first 990fx was running stable for quite some time at 4.4 ghz with 1.385 vcore or something close to that. I had pushed up as far as 4.8 stable and decided I didn't like the temps it was running so I backed it back down a bit. This new board cannot hit 4.4 no matter how high I put the vcore. what can I do to figure out what is causing this? thanks.
