Ah, so what is your VCCSA voltage? lol Answer me man! Increasing the VCSSA voltage can help stabilise RAM overclocking, and also help the CPU overcome weaker memory controllers. Some Ivybridge CPUs won't even be able to run at 2200mhz. It may also help stabilise your CPU past 4.7.
Just don't exceed 1.25v. To be honest with you it's likely you'll need better cooling to get anywhere near 5Ghz
Honestly at this stage I dont even know what VCCSA voltage is. I've adjusted DRAM voltage to 1.7v. I've lowered the frequency of the ram in anticipation of using blck to creep the ram speed back up to get a better overclock but have failed to move it beyond 100%.
So will VCCSA definately be a feature in my bios, is it always called the same thing? If you can spare me as much info as you can that would be great Frosty. (You might be able to help me reach my highest overclock )
Regarding better cooling I know the cpu is stable for hours at 100oC so my thermal load is 81oC at present, so got a bit more headroom.
