The AMD Ryzen All In One Thread /Overclocking/Memory Speeds & Timings/Tweaking/Cooling Part 2

No one hey? Not looking for pat on the back serious about the timings and anything else about the ram.

 

Looks pretty good to me, much tighter timings than mine.

 

Ya I forgot to mention that my ram is the G. Skill Flare X kit also. Only one lower than me that I can see and thats tCKE you have 8 mine is at 9. Thanks for replying, appreciate.

 

Try 3733MHz or 3800 CL16

 

Those voltages are a bit high for just 3200Mt/s.
You should definitely run higher clocks for memory. This will lower your real latencies and increase memory bandwidth.
3600-1800 should be very easy to do. 3900-1900 is a bit harder, but attainable.

Here is mine for an example.

 

OK, thanks for the advice. There are some voltage adjustments I don't know how to yet. The VDD adjustments I think it is.... or VDOC ... lol This Asus board has so many frickin' adjustment settings losing my mind and still learning this chips capabilities. I see you have geardown off too I haven't messed with that yet or the MCLK/FCLK. Also don't know about the load line calibration and phase control this board has alot of adjustments that can be done and I'm sure thats prob why some of my voltage settings are high. I did put phase on extreme for soc and cpu ...loadline on auto right now. Prob more I'm missing thats why I was asking questions.

 

Finally managed to get 4X8Gb working on my motherboard. And this is the result.
Wasn't able to turn off GDM. But the performance difference is not that big.



With 2X16, GDM off and the pervious timings, I had 57.3 Read. And 57.4 ns of Latency.

 

@Horus-Anhur
Enable ray tracing on BF5 and watch that game gobble up ram.

Try this,trrdl 5,tras 24,twr 12,trdwr 8 and let's correct the mistake that everyone makes,we do a simple arithmetic operation trp + trcdrd + trrp = 39, so the value of trc cannot be greater than 39, you have 42,
alternately change trp to 8 and trc to 41.

 

Tras on AMD is overwritten by tRC. So it's almost pointless to change it.
Considering he has a TFAW of 16, the ideal window for tRRDL and rRRDs is 4.

 

tras is high try 26-24,
trdrddd use 4,twrwrdd use 6,
for trc use 35 and not lower
this value comes from the sum of the values of trp + trcdrd + trtp which in your case is 13+16+6=35,
one more additional piece of information is that when the trc value is smaller than tras, it doesn't matter what value you give it, the trc value exceeds it and the register doesn't work, it's a normal function of the ram.

 

Like I said before, tRas is inconsequential on AMD.
tRC won't go lower than 44, or I get errors in testing.
BTW, tRC=tRAS + tRP

After posting that screenshot, I found out that it wasn't stable with y-cruncher. Bumping vdimm to 1.4v solved the issue.
I still have to try trdrddd at 4,twrwrdd at 6 with the new voltage.

 

I was going to specifically ask about this, thanks for posting. This is what I currently have but this is with just prior knowledge and not updated info, which I was just about to ask for.
