Another night at the track and some tuning. Getting a lot of wheel slippage and the engines running too rich...I know I can clock in faster with a higher trap speed in the 1/4...hmmm...in due time... Personal PR. (18660) 3rd Overall (GTX1080 Notebook Class). 1st in 775 Class. +11.3 Points for Team T|i ==================================================================================================================== Personal PR. (7238) 4rd Overall (GTX1080 Notebook Class). 1st in 775 Class. ================================================================= Personal PR. (X10967) 2rd Overall (GTX1080 Notebook Class). 1st in 775 Class. ================================================================= Personal PR. (P21413) Although this was a goofy run as it froze half way through then resumed. Strange...I'll run it again. 3rd Overall (GTX1080 Notebook Class). 1st in 775 Class.

Time was, with my old 750M dGPU, I’d load a new game, and be pleased as punch that it ran at all. Now I finally built my rig, and I’m getting all worried about performance. Generally speaking, playing with brand new games that are famously not optimized (Deus Ex, Obduction), my 1070 SC/TB2/2014 rMBP seems to do pretty darn well: 50-100+ FPS on “very high” or “ultra” settings. That said, I’m seeing two things occasionally: 1. Definite frame drops with very complex scene renders—perhaps dropping to ~30FPS and then ramping back up with simpler renders 2. Periodic hitching, where the video will freeze right up for maybe 500-1000ms, particularly in Obduction, where level streaming is happening. I guess I’m a *little* disappointed by these drops, but only in the context of the brand new video card on its own. In the context of the rig, I gather neither of these things should be terribly surprising while running a waterfall through the garden hose that is the Akitio/Thunderbolt 2 connection. According to GPU-Z, I’m barely using half my video memory at any time. What do you experienced folks generally see when the Thunderbolt connection bottlenecks? Is it similar to general slowdown in an under-powered system, or are there very particular symptoms? My guess is that the hitching I’m occasionally seeing is particularly indicative of the Thunderbolt stream, but honestly I’m not used to things performing relatively well!

While the article has no big news otherwise, they state that the release date of the PowerColor Devil Box will be the 20th October. They also state compatibility with the Razer Blade and XPS 13 notebook(s) and the Inter NUC. I wonder why they didn't include benchmark results, maybe an NDA. But they showed many installed cards. http://www.babeltechreviews.com/hands-powercolors-devil-box/ Personally I just dislike the logo on the front.

Use CUDA-Z to measure the Host-to-Device Bandwidth using the following reference. x1 1.1 would be ~190MiB/s, x1 2.0 ~380MiB/s. Reference CUDA-Z Host-to-Device Bandwidth NGFF.M2-32Gbps (x4 3.0): 2842 MiB/s link TB2 -16Gbps (x4 2.0): 1258 MiB/s link TB1-10Gbps: 781MiB/s link TB1-8Gbps (x2 2.0): 697MiB/s link EC2-4Gbps (x1 2.0): 373MiB/s link

better ask to someone who own(ed) a 980 like MrFox, but if it's like the vbios of my 970m (Prema powered), voltage slider can go up to +212.5mV. My max OC is +370MHz/+300Mhz (core/ram) @+162.5mV.

You have to wait a week.

To me bottlenecks appeared only in benchmarks by lower scores and in games with lower fps! The problems you are describing seem to be CPU related. My guess would be that the CPU will down clock in stressful situations and create a performance drop. Make sure your CPU boost is limited to 3GHz, turn off every CPU hungry app, lift the MacBook a bit up to provide optimal cooling and try lowering your CPU voltage with intel xtu (doesn't work on all MacBooks)
