Did you enable xmp?

I'm can't remember now. Shall double check tomorrow. Away to bed shortly for a 5am get up

I just looked while shutting down. When I enable docp, it automatically sets docp to 3200.
I believe from your post xmp is docp?

correct.
docp is amd's equivalent of xmp
the idea of enabling it is to enable the memory timings (rather than the speed - which you can then change independently)

Ok just reset back to standard and re-entered and it now shows coupled at 1800 .

Must have nudged the slider down for setting the frequency when I was going through the settings again.



One question, You said to set VTT to 0.7 which I did but nothing shows in Ryzen master for me. Any reason for that?

Memory latency shows about 70.9 now. Previous just setting DOCP and IF to half had it around 76ns. I'll be happy with a higher 60's figure.

 

[tamzzy]

Any reason for that?

not sure about asus boards tbh.

Ok dokey, Well thanks very much for the tips. Appreciate it!

 

[michty_me]

Quick question, What sort of benefits in games are you likely to see from dropping the memory latency successfully from 76ns to 70ns or 70ns to 68ns. Any big differences?

 

[michty_me]

Done some tweaking with the help of DRAM calculator on their fast setting. Anything standing out that is looking dangerous or wrong?

Edit: Found it.

 

[tamzzy]

what chip do you have? your cache speeds seem a bit off compared to what i've seen from other benches

It's a 3600 non X

 

[tamzzy]

ah ok. fair enough...seems about right then: https://gorodfinansov.ru/obzor-prot...-3600-shestiyadernik-zdorovogo-cheloveka.html

That's good to know.
My voltages are as follows:
SOC 1.1v
DRAM Voltage 1.45v
CLDO VDDG 0.950v
VTTDDR 0.725v
VDDP Standby 0.9V

I seem to remember reading 1.45v on the Dram voltage is a bit high for a daily machine. Maybe I should drop it back a little?

 

[tamzzy]

1.45v is fine. 1.5v is max.
But ideally closer to 1.4v is preferred.
3600 should be doable at 1.4v

Cheers tamzzy, Will start nudging it down and watch to see if it becomes unstable.

before you do that, i suggest trying to turn off geardownmode
1T with GDM = off yields an instant 2-3% performance gain in comparison to 1T with GDM = on
from what i've read anyway...

I'll give that a try before I do any changes then!

 

[Psycho Sonny]

Nice i have mine stable with same settings

copied all your settings



no idea what is going on - zero improvement over stock

 

[tamzzy]

@Psycho Sonny looks like you have not coupled memclk to uclk and fclk. Latency = 78ns usually suggestive of uncoupled mode.

Set both to 1900?

Tried that now I can't even get into the bios anymore.

Might just run at stock for now

1900 is an overclocked infinity fabric. Not all chips can do it
Before you overclock the ram, it's imperative you find out what the max infinity fabric speed your chip can run
