my e8500 is having trouble hitting 5ghz

priming 4.25ghz right now though @ 1.376v (8.5x500). will update this post w/ pics once it hits 1 hour.

passing 20 min... means nothing just counting down. i could probably do a better mount on the cooler though... load is -19. i dont remember if i used thermal paste or not lol!

I doubt it's your mount bro. My E8500 does 4Ghz at 1.20v [BIOS setting], and 4.25Ghz at 1.30v [BIOS as well]. Seems to me that anything passed 4Ghz requires a boat load of vCore, and if yours is requiring 1.37v for 4.25Ghz, then you gonna have to juice the hell out of it to get it to boot at 5Ghz.
Unless you are just trying to see if you can hit 5ghz with it, I would say forget about it since it is just not worth it, at least not to me. The fact that mine needed .10v for a mere 250Mhz, when it only needed .025v from the VID [Core Temp and Real Temp showed the VID for my CPU at 1.175v] to overclock from 3.16Mhz to 4040Mhz. In my case, I'm extremely happy with the purchase and the performance gain from the OC; I'm getting some nice Super PI timings at this speed with my RAM running at 2000Mhz [without tweaking yet, set to 8-8-8-16-1T 1.95v]. Once I iron out some kinks in my config, it should be rock solid.

my remount resulted in -24c which is a bit better than before. im trying to get my 24/7 setting dialed in before i start benching more @ higher mhz. i dont want to just hit 5ghz, i want to bench @ that speed. excessive vcore is no issue to me. ive only had this cpu for about 4 hours now so i still have some fine tuning to do to drop volts a bit more. i just gotta quickly set it up for tomorrow.
