So I dialed back the voltage, dropped the overclock to 4.1 GHz, and kept the cache multiplier to 40x. Also, I think it is important to note that although I don't understand what Iccmax is on the processor, it did greatly impact performance. In my XTU settings, 65A is the conservative power-saver default, 95A is the 'turbo' default, and 100A was my overclock setting. Anything over that simply generated more instability and heat. It seemed that when Iccmax is reduced, the cores do not actually reach their desired frequency, or are unable to hold it under load. Hitting only 3.8 on all cores on a 4.0 GHz overclock) Power limit was maxed (to the power limit that the brick can provide of 230 watts) a +.030 V offset, and a multiplier of 41x on all four cores. To those interested I also overclocked the GPU using the same methodology of finding the ceiling and stepping it back a notch. I achieved an offset of +145 MHz on the core, and a +885 MHz overclock on the memory. I'll add that I think I got lucky on mine, with the overclock it scratches around 2000 MHz and performance is great on it. (I get 80 FPS max settings on Witcher 3 ).
With 4.2 I was thermal throttling all the time, hitting the 100C ceiling on synthetic loads. I did an Aida64 stress test with the FPU instruction set, and I again was getting low 90's with spikes into 100C, throttling the cpu again Backing down to 4.1 and lowering the voltage helped with temps around 80-85 under a "real-world" load, but temps were far to high for my liking. So, I re-pasted the CPU and GPU (while I was at it, temps were 65C under-load and not a concern), and the new compound worked very well. Temps in the mid 80's with a synthetic load, and mid 70's with a 'real-world' load and other synthetic loads that aren't as hard as aida64. Ive posted the results before and after below, and although not perfect, much more manageable. I did still see some spikes into the 90's which triggered some minor throttling in Aida64, but none ever reach 100C. With a working temperature in the mid 70's under heavy load, I think this is much better, especially with a decent overclock on a laptop.
Oh and the GPU temps improved by a whopping 1C. Final side note, this was a replacement for my desktop, as I wanted my gaming but needed better mobility. So I sold my beast of a machine and got this about 6 weeks ago. I purchased this from Newegg as open box during one of their open box sales. The benchmarks and the before and after temps using aida64 after re-pasting the CPU and GPU with Kryonaut:ĬPU wise. I think u have a terrible chip there RIP. I'd say keep it even at 4.0ghz for rock solid 24/7 stability. XTU could be the issue also because XTU is fucking terrible.
