Having trouble getting stable at 4.7GHz and want to push higher for fun but would like to leave it around 4.6-4.7 for daily use. After 15 mins prime 95 blend worker 4 gets an error. Help would be greatly appreciated. Thanks!
Ambient Temps - 23C
Idle around - 27C
Under load - Max 61C <-- REALLY GOOD temps!
Max under load should be 85C. It will rise alot with vcore but will be perfectly fine. The chip won't even shut down till a whopping 98C.
BIOS settings are below:
BCLK - 100 X 47 Multiplier
Vcore - 1.35 in cpu-z Wowsers... thats really low imho. 1.5v is the max for me, and almost all agree that 1.45v is the low max. So I would at least got to 1.4-1.45v and try to get stable at 4800MHz.
LLC - Level 2
Voltage offset + .090v
Internal PLL - Disabled (possibly need to enable for higher OC's but would like confirmation) Enabling will help a TON, but It may cause Sleep problems (or it may not, different across boards). Try going to your max vcore before enabling this if you want.
Spread Spectrum - Auto Disable this.
Dram - 1.529v 1600mhz XMP
PCH Voltage - 1.059v Leave auto.
PLL Voltage - 1.832v (I've read that's set pretty high and might want to reduce it) 1.89v is the limit, however raising it rarely affects overclocking.
VTT - 1.047v Leave auto.
VCSSA - 0.925v Leave auto.

Gave you some tips, which almost all are in my guide.

Now ANOTHER issue that I am having... is that several games will crash either when loading at the begining... loading in between levels... or when exiting. The worst is NFS The Run... which will crash and then I can kill it through the task manager, but will BSOD right after I kill it. It's usually that the driver has stopped working... with a 126 BSOD.
Any ideas on what could be causing this?

That BSOD isn't on the list of related ones to Overclocking the CPU, so I would suspect that your GPU drivers are doing it. I would get the latest drivers from AMD/ATI for your graphics card and make sure that you pass the final test on my guide. Also when you install the drivers, make sure you do a clean install, or use driver sweeper to wipe the old drivers out.

Lucky!!!
I tried so hard to get 5GHz but my chip won't go more than a min in prime95 at 5GHz even with a 1.52v. But I've learned to let it go...4.9GHz is blazingly fast.
