Below results are all run at 3600 Mem and IF with Dram Calc V 1.7.3 Membench Default for comparison between 2 and 4 sticks of Dram at exactly the same Bios settings.

3600 Default scores
2 sticks 199.91
4 sticks 195.48

I wonder what's bumping the score since the read and latencies are both a lot worse than mine?
Could it just be down to having 24 threads as opposed to my 12? Does running a test with 12 threads result in a higher time?

You can see here it comes with three configurations (specifications tab)

So it will definitely (99.99999% assurance) run at 16 16 16 16 36 3600MHz at 1.35v and should be overclockable well beyond as well.

I can only speak from my own experiences. That yes I was able to run it at CL16 3600MHz. I am currently running it at 3600MHz CL14 (1.47v) and others have run it at 3800MHz CL14 so I can't see why you would have any issues either.

Thanks :) 3600CL14 is a pretty incredible result for a 3200MHz kit.

Sounds like it might be worth spending the extra ~£22 for the TDPPD432G3200HC14ADC01 (32GB 3200CL14) kit over the Crucial Ballistix 3600CL16. Really kicking myself for cancelling the pre-order I had for the 8Pack 32GB 3600CL16 kit when it was £199.99.
 
@Joxeon the test differs between 12 and 24 threads.
Already discussed either earlier in this thread or another from memory i think the task scope is different while the test is running.
Basically the 24 threads are given more work to do to keep the results comparable.

Each thread is given 15%. So it scales based on number of threads.
 
Oh wise ones, show me the error of my ways!

I've been out of the loop for a number of years, and just got my 3600 + B450M Mortar Max + 3600mhz CL16 Dark Pro set up on Sunday.

As expected, the default XMP timings work a treat, but gave me 320 seconds on the DRAM Default test.

I've played around with a number of recommended settings from both 1.7.0 and 1.7.3 of DRAM, and the tightest timings I have managed are below, at 1.48v DRAM and get 30 minutes of Karhu RAMTest with no issues.

Now are these to be expected from my set up, or should I be able to improve things?

I want to test scaling back the voltage, but first I want to get in the right ballpark on timings.

Thanks!
 
Try to get tFaw nearer to 16.
tRFC closer to 300.
tWR normally matches tWTRL which for you would be 12.

What Dram PCB revision did you select in Dram calc?
 
Whats your Motherboard ?
I ask because the timings you are using seem all over the place.

You seem to be using Safe option? and even then some still do not match.

Please use the FAST option, after all you have purchased top quality memory which is wasted if you do not enable the best profile.

Safe option does not mean it is SAFER to your hardware it means it is more likely to work if you cant run FAST and don't want to tune if required.

Although i am sure just making the changes I have already suggested should be a big improvement.

Thanks, MSI B450M Mortar Max

The timings are the same as what 1.7.3 gave me as Safe, but I reduced tRFC from 468 to 330, which I see now is apparently supposed to be 8*tRC (or 8*tRC+8) according to some in depth Reddit post.

I'll try the Fast settings, but I am pretty sure when I did it wouldn't post.
 
Well I changed:

tRRDS = 4
tFAW = 16
tRAS = 21
tRC = 35
tRFC = 288

Posted fine, but only knocked 2 seconds off Easy and 6 seconds off Default.

That said, if it is RAMTest stable, I think this will do me fine, haha
 
Closing in on the 200 barrier.
