yosarianilives Posted March 13, 2018 Share Posted March 13, 2018 Well it looks like I owe you all an apology for being an idiot. I was doing some testing on my 7700k for hd graphics 630 to try to get some vindication and was getting really confused why my apex could only do about 1450 mhz on the igpu core when my soc was running "1926" mhz just fine. So I swapped back to the POS z270 soc. Boot at 1500 mhz multiplier just fine and I decide to double check clocks with gpu-z. To my surprise it read 1150! So as it turns out igpu multiplier is completely broken on the z270 soc, add that to the list of things that don't work right next to 1t cr. So I did the math for the bclk I was running with the multiplier I was actually running and it comes out to just about the same mem mhz that I was running on the apex. So it seems that on ss 1500 mhz really is the igpu core limit more or less. So I'd like to apologize for suggesting that you guys might've been doing something wrong, when it was really that I was an idiot the whole time. (as I suspect many of you already knew) Also after my testing yesterday I can say that it seems that the subtimings priorities are not necessarily exactly the same as on ddr3 platforms as I didn't see the same kind of scaling I'd expect. So while mem is definitely important I can't say I have a clue what you need to do other than have fast/low latency ram. Now if this was ddr3 based intel graphics I could give a fair few more pointers Hopefully I can learn a bit more about this part of my niche as I work towards becoming the intel igpu king (intel gma will also be interesting, I have about 15 boards and plans for dice lined up) 1 Quote Link to comment Share on other sites More sharing options...
