I looked at the sticky guides and have began to test some O/C scenarios using the quick setting option for 4.0 and 4.2 GHz. This changes the multiplier and BCLK remains at 100. I set CPU to 1.1v and it runs stable. In one of the guides it talks about changing the BLCK. In the BIOS it says it can be set up to 150. However when I change it to 150 and lower the multiplier to 22 so it remains at the stock 3.4GHz or slightly lower, when windows has loaded up and I check with CPU-z the multiplier is at 22 but the BCLK is unchanged at 100, effectively under-clocked to 2.2Ghz. I can't seem to find any info on what this is happening. Also in the one guide it mentions IOH voltage but I don't see IOH voltage. Aside from that I haven't gotten any farther with my experimentation since these two things have me unable to proceed until I know what is going on with them. Basically I'm looking to squeeze a little more out of the CPU for gaming if possible. I haven't messed around with O/C in awhile now and have been itching to play around again. So any advice or guides or what not ya'll have for me would be great in addition two these two specific things in question in this post. Thanks.
