i just read a toms article on it, so i just increase the multiplier (33 i believe) to 34, then test (prime95) then raise to 35, then test. Once i hit instability i start on the voltage increase? does this sound right?
aside from a lower life expectancy, what is the reasoning behind not clocking high. I have always thought the life expectancy of these chips was enough that by the time they die, they would be ancient anyway.
Not sure if i want to sit around for an hour waiting for Prime. Any ideas on a good game to stress it? Whatever games i play it never seems like they stress it as much as prime95 does.
Im thinking either Starcraft 2 or Battlefield 3....
Auto usually overvolts, sometimes it's fine. You shouldn't need to change any other settings except multi and vcore at that speed. Just keep the vcore below 1.4v and temps below 80 in prime, 72 in normal usage. The 212+ should get you around 4.7 depending on roomtemp before temps become a bit too high. I would still recommend stress testing in prime as a game just won't stress it enough to really test stability.
I use offset or else speedstep isn't really doing anything. What is your roomtemp? What are you using to check vcore and temps? What is the bios saying the vcore is when you set it to 1.365? It may just be vdroop, adjust the llc if it is saying 1.28.
when i set the vcore to 1.365 it doesnt go up in the bios, i assumed this was because the CPU is not under stress.
So are you saying instead of changing Auto Vcore to Fixed, i should change it to offset? whats the difference between the two?
Core Current limit at 150 isnt stopping it is it?
Also iv heard some people getting better results with LCC at 1, not sure though
edit: well tried just as a test to see if vcore would go up. its stable at stock Vcore and multi 45. So i kept it at 45 and put vcore up to 1.35. it still wont go up. I tried prime95 and it still wont go above 1.28
In bios the cpu is in full load state at all times, it cannot change state. The vcore issue appears to be vdroop, adjust the llc.
Offset allows the vcore to lower when idling, stock is ~.95 at idle, 1.2-1.25 in turbo. Auto is not stock, it will change vcore and often overvolts when ocing.
You can change these if you'd like but they probably won't make a difference,
Internal PLL Overvoltage: Enable
Turbo Boost Power Limit: Manual
Set Short Duration Power Limit: 200
Set Long Duration Power Limit: 200
Set Long Duration Maintain: 56
Core Current Limit: 200
Spread Spectrum: Disable
Not the first time I've seen this but it wasn't the extreme3. I never really looked into the solution though. Truthfully there's really no point in having it run that high for 24/7 use. I keep mine stock for gaming, still plenty of power that my 560ti is still the weakest link. ~1.4v is as high as you want to go. ~4.5ghz is really more than any game/gaming setup needs.
