With most kits, we are trying to claw a few extra megahertz and 4GHz+ is usually rare. GeIL already starts us out at 4133MHz, so let’s see if there is any more under the hood.
4266MHz is no problem.
4400 MHz comes and goes.
4500 MHz still isn’t an issue.
Neither is 4600 MHz. still at 1.4V and C19 timings.
We ran into a problem at 4700MHz. no matter what we did, it just flat out refused to even POST. Loosening the timings down to C25, voltage up to 1.55V made zero difference, 4700MHz just wasn’t going to work. 4666 MHz however still works at 1.4V and factory 19-19-19-39 timings.
This gives us well over 60GB/ reads, 66GB/s writes and 55GB/s on copy at a great 42.2ns.
This gives us almost 2000 more points in Passmark’s Threaded Memory Mark test.
