Yeah I'm really sorry I haven't gotten back to you guys. Up here in New York it's the week before the week before Spring Break for high school, so all of my teachers dumped homework and projects on me like no tomorrow, doesn't help I'm taking 4 AP's either. Since it's Friday, I plan to take a look at RAM timings and such after work. I think I decided I'm going to keep the 4.3Ghz because putting any more vCore through the chip as my 24/7 rig probably won't be a good idea. If I was benching, it'd be a different story but I'd like to keep my chip for awhile. At this point, I've read that AMD chips react very well to lower RAM timings so for here on out I'll probably start messing with those and post my results for the rest of the community.
If you really want to hit that final 4.3Ghz or higher, try going to a 19.5x multiplier first, and if that causes too many issues, start bumping the FSB up in increments of like 2 or 3 until you reach a wall. I can't remember if you told me what kind of cooling you have, but this is an instance where I'm extremely happy I went with watercooling. The second I stop my Prime95 Blend, my temperatures plummet and they stay very low.
Keep you guys updated for sure.
