Note: Be sure to test before and after! It is not always the case that this procedure will improve benchmarks & scores. But you can increase the speed of the Infinity Fabric with slower memory kits. Sorry about the Moire shirt! Will set on fire now, this was shot at the same time as the temps video.
Crucial Memory Speed vs Latency:
Note there wasn't time to cover command rate (1T vs 2T) in this video. If possible try to get memory with a command rate of 1T for now. Working on something special for that!
@wendell Unfortunately someone/s (it has been more than one I am sure) destroyed the sheet you posted on docs. could you possibly put a write protected one that can be copied off please. Can't have nice things anymore it seems.
On a happier note, I have loved the content of your channel. Please keep going.
Anyways, I've noticed the same thing a couple months ago when I was looking into the differences between DDR3 and DDR4. I though it was odd that even though the speed of RAM went up quite a bit, but latency also went way up. After some digging it appeared that DDR4 had pretty much zero improvement over DDR3. I'll have to see if I can dig my post up about it again.
Yes thank you very much, I am waiting for the r5 release to finish my build and the ram I bought is 16gb @ 3200 126.96.36.199 can't wait to see if I can push it further and your chart has taken alot of the headache and guess work out for me.
I have the same memory as this, been trying to get it up to even 2933 without much luck. I can only offset the voltage up to 1.3v on the asus b350 prime which i think is holding it back. I'll have another bash when my gb x370 k5 gets here. (pre-order only 30 days overdue, surely it will arrive soon :^)
I assume setting 3200 and just going back and loosening the timings until it boots is the way to go when OC'in ram? or will there be points where no matter how loose the timings are some mobo/imc just won't boot at certain frequencies?
A little Wendell mojo got me past the final roadblock. I have a Corsair Vengeance 2x16GB 3000MHz kit that I couldn't get past 2666. It's often said "loosen the timings" but never said what exactly to loosen them to, and on the AX370 Gaming 5, guess work = boot loop.
I plugged the stock timings into your chart, 15-17-17-35 and got 20-23-23-48. I popped them into the BIOS and finally got 2933 without bootlooping.
Plug the timings into the spreadsheet and see what it says. Also 1.35v. there is a button next to the oc button that's supposed to reset ram only but the software may not be hooked up yet. You might also wait a full 2 mins before giving up on post as first post may be tricky.
You on the beta bios? Asus has been way more test heavy on their uefis it seems so seems longer between updates. There is a bug update dropping next week for sure but I didn't tell you that
