Worth upgrading mixed ram?

[j.col]

I agree.

At least if tested at there rated speeds will confirm they all working correctly then the tinkering starts .

I tested just the 2 sticks and they ran at 2400mhz.
I then tested the 1 stick and it ran at 3200mhz

Then i noticed DOCP was off, so i enable it.
The 2 sticks then ran at 3000mhz.
I didn't bother testing the 1 stick again.

So now with the 3 sticks back in, i am now running at 3000mhz

1 stick of ram only

2 sticks with DOCP OFF

2 sticks with DOCP ON

And finally all 3 sticks with DOCP ON

Is it using 1.35v?

I suspect when you enabled DOCP it put the DRAM voltage to 1.35v, which is fine for the TEAMGROUP sticks, but strictly speaking an overvolt for the Crucial.

You are correct, is it ok to carry on in your opinion?

passmark ram test, only test i could think of atm

1 stick

Passmark 2 sticks only

passmark with 3 sticks (not much of a jump in performance tbh)

The PC will probably be obsolete before the ram dies, but if you don't care about the performance (e.g. this is an office PC and you don't play games, or only very light games) then I'd turn off DOCP.

Thanks again for all your help.
I will probably leave it on for now as i do play games on it.
I will keep an eye on the MM in case a set of ram pops up.

@j.col Great result and 1.35v will be fine as brother @Tetras pointed out but don't forget the 16gb is still in single channel configuration.

What gpu do you have ?

don't forget the 16gb is still in single channel configuration.

So long as it is 2x8 in one channel and 1x16 in other channel, should be dual channel across the lot now

There's so much conflicting articles about this I'm still unsure , how can you tell ?

I did a bit of googling and couldn't find a concrete answer. It sounded like there was some sort of flex mode, but maybe that got phased out at some point. Not sure. Hence me sticking to advice that's consistent with the mobo manual.

Just a 1070ti, it does the job for now
