You might be able to drop the PLL voltage and vcore a little bit more and maybe shave off a couple more degrees during IBT testing. You'll wanna do some more stress testing before you start dropping the vcore or alter other voltages. Most likely they will be about 15-20 degrees lower or possibly more anyways. Try some gaming out and everday use and see what your max temps are.
Not sure about max memory as you have 16gb's so maybe try it with 8096mb or so.Unless you can get the temps inline as it'll take a long time to complete even 10 runs. You should test with more memory tho at least go up to the 4096mb setting as you can get bsods when using more memory. In the low 80's would be fine during IBT. Intel Burn Test is killer on the temps as you've seen. The values OCCT is giving you seem to be correct now.

The AXTU software was most likely messing with the OCCT readings. Your rig does throttle down to 1.6ghz with vcore around 0.980v's or so now doesn't it? Changing this value will only drop the idle voltage. The voltage offset value is for idle voltage.

Trial and error will get you were you need to be. Dropping the value 0.010v's doesn't always get you 0.010v's less vcore tho. Dropping this value will reduce your loaded vcore. The additional turbo voltage value I gave you was just to see what your rig would get with loaded vcore. Your on the right track now it looks like. Thanks everyone for all your great advice, I really appreciate it.Ĭlick to expand.Did you enable the CPU Thermal Throttling setting? You need this enabled as a just in case your cooler can't hang. I need to be spending this time studying for my exams :/ Yeah i'm probably wasting my time trying to get 4.8Ghz and I should just put it back at 4.5Ghz were it was running fine. If you want a laugh watch this timelapse I made of me building my system: I can always just put it back to 4.5Ghz were I had it stable before. Built it mainly for photoshop and now trying to push a tad more out of it as I've ordered a Nikon D800E and those 36.3mp raw files need a lot of juice to push around. I might sound like a noob and thats because I am haha, I only built this system about 6 months ago and before that I never built my own desktop so trying to learn as much as I can. So should I start with a low vcore again such as 1.37v in the bios? and if that doesn't work try adjusting the Vccio,VTT,PLL voltages? What temps should I be trying to stay under in IBT? Ok I will try punching those settings in and see how it works. This is how you'll want to take control of your loaded vcore. Take the additional turbo voltage off auto and give it a value of 0.050v's or so to start.
The short/long duration and current limit don't need to be set that high for only 4.8ghz but doubt it would hurt anything as your chip won't be pumping that much juice thru it at 4.8ghz anyways. If it doesn't need it to boot at 48x then it won't do much for stability if you have it enabled. Internal PLL overvoltage may or may not be needed for your chip. In the following screen shot the setting can be at defaults for 4.8ghz. (Doesn't like AXTU on my rig) If you click on the time box it will show watts which will give you an idea of how much power your waisting stress testing Try latest version of RealTemp to monitor temps. Uninstal the AXTU software as it's useless in my testing. If your goal is to fry your chip then carry on Just save your current profile so you don't loose nothing but some time. I'd suggest starting over from scratch if you want to get 4.8ghz stable. When you don't play around with all the c-states the chip will just throttle down speed and voltage to save itself from damage or early demise! I've had my chip all the up to 5.5ghz and haven't touched some of the settings you seem to be thinking you need to use. It throttled as one would expect but lives to tell about it.
