DRAM Calculator

Kevin Matthews · 13 Mar 2020 at 20:57

Hi Guys,

Tried using the DRAM calculator to manually change the timings. So once run memtest86 once it gets to test #6 starts to show two errors. Don't get no BSOD or anything before hand even with Xmp. Any ideas?

Thanks
Kev

If your getting errors then it's not stable so you would need too adjust timings or try bumping the voltage.
Are you trying safe or fast timings?

Is it worth it I've XMP normally which seems to be fine, what would you suggest?

Here are settings I used sorry for the phone picture.

What are the timings when you set xmp?

In bios or cpu z?

If you have ryzen master installed this should show all timings and voltages.

Ok what I would do is dial in 3600 speed in the dram calc and see if you can run with the timings it spits out at either safe or fast.

The first screen shot was the safe settings with alt trfc

Running 3600/16 is the sweet spot on ryzen 3000 and maybe easier to achieve stability over 3200/14 and will also perform slightly better as you get the benefit from a higher infinity fabric.

Set the speed on dram calc to 3600 and try safe timings.

OK mate, also the section with trfc and trfc(alt) in bios I've got trfc 1/2/4 which changes to the same for all? I've just left on auto.

When I run memtest if I get errors would you increase the voltage slightly?

What's the highest you would go to?

Memtest has been running now an hour stilll no errors.. How do you check for stability @Joxeon

I normally leave it running over night just to make sure I would say a minimum of 4 hours to be safe.

If you go to the membench section on the dram calculator there is a memtest on their which is pretty good.

Okay, well might aswell wait for this one to be finish not be long.

Hi @Joxeon

Just wondering if you can help me improve latency. On the dram calculator it says best result is 108. 5 and my current result is 128.42 for 3600.

Everything been stable no crashes.

Thanks
Kevin

Joxeon · 27 Mar 2020 at 17:16

What's the actual latency for that score?
