[SOLVED] If paired ram goes in slot 2/4, what slot would unpaired ram go into?

Solution
By order, it should always be second slot, fourth slot, first, and then third away from CPU.

2/4 & 1/3

If attempting unmatched RAM, it's the same, however need to test to see if modules can pair well to run in dual channel. When 2 slot communicates with 4, it's going to be different since they are not perfectly matching, so typically good results can be challenging for these mismatched scenarios.

I would not pair RAM that is different, especially different brands.
You will have nothing but problems if you pair RAM that is rated for different speeds, voltage, and timings.
Not to mention if they are different sizes.

The only reason "paired" RAM goes in 1/3 or 2/4 is for the sake of dual channel.
That is it.

I've been doing unpaired ram for years. I've done 1/2 as to my brothers advice and seems to work. They're the same voltage and speed so shrug, one kingston one crucial, and the one time i go to buy dual RAM they come faulty lmao.

lol, sorry to hear that you got a bad kit, but if you bought new, then that's what a return policy is for.

If the RAM is the same speed, timings, and voltage (please note not just speed and voltage but timings as well) then despite the fact that you may possibly have two different sized sticks (you never specified) then just throw them into any slots you like and see if it works.

The worst that could happen is that the system either crashes during operation, or it won't even boot up properly.
 
To pair them in Dual Channel mode, you need one in the slot a, and one in slot b. If you pair 2 sticks in both slot a or both slot b, then you lose Dual Channel Mode.

If only using 1 stick, using Slot A2 is preferable. To get Quad Channel, you need sticks in all 4 slots.

Using memory from different companies is a crap shoot. You may get lucky, you may not.

I may of been wrong. My apologies. My old unpairing RAM worked before but I went into slot 1/2. Yes it fixed my problem but then created stuttering in game.. my games would lag way too hard, especially wildlands, the other game I tested (Csgo) was not to the extreme but still slightly noticeable....

If only I took note of what slot it was in before, im running a MemTest86, but maybe I should try slot 2/4 instead of 1/2? Even though they’re different brands? Thoughts?

You can use CPU-Z by CPUID and go to the SPD tab and it will tell you what you have in each slot. Download CPU-Z here.
 
I already have this? I’m confused what you mean. Both RAM is detected but they just may be in the wrong slots? (In 1/2). The MemTest86 came back fine so I can only assume it’s a slot issue

There are 4 slots....typically names A1, A2 B1, and B2. If you have both sticks of RAM in your system side by side then you likely will not be getting Dual Channel on your memory.

To get Dual Channel memory, you will need to put 1 stick of RAM in slot A1 or A2, and 1 identical stick of RAM in slot B1 or B2. Typically it would be A2 and B2.
To get Quad Channel memory, you would fill up all 4 slots with identical RAM.

Dual Channel memory configuration would basically double the amount of memory bandwidth your computer would have. This would help with the stuttering that you have been having.

To check this, look in the MEMORY tab of your CPU-Z. Top right will tell you if you are running single, Dual, or Quad channel setup.
