Perhaps you can get a case with better airflow? Many modern cases have a top exhaust fan which should help stop hot air build up at the top of your case and prevent them from being sucked back into the heatsink.
You didn't mention what your CPU cooler is, but changing it to a higher performing one will give you direct gains. Noctua NH D-14 and Thermalright Silvera Arrow are I believe the top 2 coolers, but my info can be outdated.
Also do bear in mind CPU air cooling is highly dependent on case airflow so for the best result, don't skimp out on getting a good case.
If you really can't improve on your thermal performance then like Ellis said, you will want to down clock it a little.
From my knowledge BSOD 124 can either be VCCIO, or VCORE, and in rarer circumstances, PLL. I would first look into VCCIO first, then PLL, and only tweak VCORE as an absolute last resort because it will increase temps much more than the other 2 voltages.
Sounds like you are using manual OC. In manual OC, voltage @ idle and @ load will always be the same so that is normal, additionally, LLC is used as a mean to ensure the board delivers exactly the amount of voltage which you keyed into BIOS into the chip. If you's entered 1.250V into BIOS and CPUZ reports 1.248-1.256V, then I believe the LLC is spot on at the moment so you don't need to change it.
I will however recommend offset OC over manual because your chip at idle or at light load simply doesn't require a large amount of power. As every bit of voltage pour into your chip will reduce its lifespan, you would want to reduce that amount when it doesn't require so much power. Also, it'll save you money on your next electricity bill. There are plenty of offset guides online as well as this very thread.
Yes, I am using manual voltage at the moment. I thought about using offset voltage but decided it might be better to first use manual until I know which voltage setting I want, then try to achieve that with offset. But you're probably right that it's easier just to use offset voltage from the start.
I impatiently decided to go ahead and increase Vcore 0.01V so that it's now running 1.264-1.272V under load. My LLC was previously set to auto and I believe that had selected ultra high for me - now I've manually set LLC to ultra high and voltage to 1.260V. High LLC only gave me around 1.24V or something
Anyway, I am now nearing the same Prime95 mark as before, to be honest if this is stable for 12 hours at this voltage I probably won't try lowering Vcore and messing with VCCIO because I'm already running a pretty nice voltage for 4.5GHz. But if it crashes around the same mark again, I'll try switching to offset mode and tweaking VCCIO EDIT:

I'd try the lower multi (x46), +0.065 offset or lower if possible stable and 1.55 pll your temps will lower a bit, but not significantly however enough or within reason to get you by. As you mentioned while gaming your temps are reasonable so I would not worry about 80-90c at 100% load unless you run at 100% load most of the time then I would have to agree with ellis move to 4.4/4.5. BTW I would enable HT and take advantage of your procs abilities even if that means a lower clock overall as a result.
@ellis I have a couple Qs Are you using offset or manual Vcore? your current vcore is low enough that your heat should be in check and you should have room for higher vcore. Keep in mind you can get a 124 stop with to high or to low pll but for the moment vcore seems a bit low and a bump there may be all you need. I'd also like to know your other current settings auto or otherwise.
AI OC Tuner:=?
Internal PLL Overvoltage:=?
CPU:= offset? or manual?
CPU Spread Spectrum:=?
As said above I'm using manual voltage mode at this time, and yes, this is a pretty low voltage for 4.5GHz which is why I decided to increase Vcore rather than VCCIO.
OC Tuner - never touched
Memory - XMP (1600MHz 9-9-9-24 1.50V)
PLL overvoltage - disabled
LLC - as said above, now ultra high
VRM frequency - 350
VCCIO - auto
PLL - auto
Spread Spectrum - couldn't find the setting! So it should be on default
C1E - enabled
C3 - auto
C6 - auto
I think that's it Edited by Ellis - 11/24/12 at 9:23am
