I have a dell 7510 laptop. it came with a single 16 GB cas 15 2133 dim. my tests were unimpressive - https://browser.geekbench.com/v4/cpu/1234395
I bought 16x2 cas 13 2133 ram. this fared much better - https://browser.geekbench.com/v4/cpu/1265208
looking at other people's results, on the same box, my bios seemed out of date. I updated it and did better - https://browser.geekbench.com/v4/cpu/1265388
it is at this point I am wondering what more I can do or why some of these scores best mine. my single/multi memory bandwidth values are 24.9/25.5.
this test is the top for this cpu, i7-6920hq - with 16 GB ram and bandwidth 25.4/27.2. https://browser.geekbench.com/v4/cpu/572132
this 32 GB system is next with 26.9/29.4 - https://browser.geekbench.com/v4/cpu/445607
this 64 GB 7510 has 26/27.9 - https://browser.geekbench.com/v4/cpu/1012534
I suppose it is not clear how the bandwidth/benchmark relationship exists, outside of just knowing my slower/single channel ram was a problem. but i'm trying to understand how some of these tests are beating me in that we have the same chip, and I don't think you can buy any faster than cas 13 2133 ram for this board. so what is causing these differences?
