My new laptop is awesome.
As I expected, 15.6" is a little annoyingly big, but I'll live with it for my vision. Its awesome.
It has an i7 4710HQ, 8Gb of transcend ram, and a Dedicated GTX860 with 4GB of GDDR5
For one, I cranked the thing to max, using FURMARK and PRIME95 simultaneously.
The fans are NOT as loud as people suggest (maybe I have a newer revision?)
It maxes out at 82~84*C; not bad for shared heatpipe cooling.
I then re-pasted the laptop using Gelid GC-Extreme.
The same test resulted in 78~81*C; how bloody awesome is that!!!!!!
So, with my fresh windows install I have now proceeded to install Intel XTU and started undervolting. Yeah!
And, so far, it looks like I've managed to hit the silicone lottery!
I'll update as I progress, but so far, my results are as thus:
- 80mv Core stable (5min)
- 90mv Core stable (5min)
- 91mv Core Stable (30min)+(5min)+(2min)+(10x 1min)
- 93mv Core CRASHES (5min)+(2min)+(1min-x4)+(30min crash)
- 95mv Core CRASHES (5min pass)+(2min fail)
-100mv Core CRASHES
Yep, that's right, it looks like the i7 4710HQ, the slightly higher clocked, slightly more energy efficient version of the i7 4700HQ, is edging stable at a -92.7mv undervolt!
Temps maxing out at 69*C (but thats without GPU).
I did the multiple 1 minute tests, as the 'fail' normally happens during ramp up\down of speed, and the half hour test is half way through right now.
Next I try to undervolt the CPU LLC (L3 cache) to match the core (its normally happy to do so), then the onboard GPU.
It's going to be a FUN day!!!!!!!!!!!
93mv crashes during the half hour test. Last 2 Minutes. SO CLOSE!
Will try 91mv next.
Minus 91mv has passed 5 minute, half hour, and 10x 1minute. For now, STABLE.
Moving onto CACHE undervolting, then GRAPHICS.
Minus 90mv CACHE has passed 3x 5 minute 'Memory' tests, and 3x 5 minute CPU tests.
Considering thats almost 1:1 with CPU core voltage, moving onto on-chip GPU. (the NVIDIA wont be touched)
