Which RAM?

[heady scroll]

Ok so I built my PC around Feb-March time and bought myself:

Corsair Vengeance LPX 16 GB (2 x 8 GB) DDR4-3200 CL16 Memory

The other day through a family friend I have been gifted:

G.Skill TridentZ F4-3200C16D-16GTZB
(2x8GB)

And:

G.Skill TridentZ
F4-3000C15D-16GTZB
(2x8GB)

I do not know the background usage of the G.Skill ones so don’t know how well they’ve been treated.

Which ones should I use and which slots should I put them in?

What motherboard do you have?

Check for compatibility list of the motherboard, if either of them is not listed, you have problem solved

And for slots it's almost always second and fourth, but check your manual

in a perfect world you should use the same type sticks for all slots but if you have 4 slots then place the G.Skill TridentZ F4-3200C16D-16GTZB
(2x8GB) in the open slots that are no in use

If he asked for slots, he means to replace the old ones with new pair probably

Which ones should I use and which slots should I put them in?

from what i can gather he has 4 slots and wants to use as much ram as possible

so all 4 sticks running at 3200 and cl16 is good

then sell the pair of 3000MT ram

[nimble hawk]

almost anybody has 4 slots, so if he has 2 slots free, he wouldnt ask

@wintry zenith was right

i had 4 slots

and 6 sticks of ram but i wasnt sure which sticks to use in which slots

i have now put all of the 3200 sticks in and im giving the 3000 sticks to my mate
