Memory Question
August 9th, 2016
I have ordered additional 16 Gigs of Crucial memory [ DDR4 ] to give me a total l of 24 Gigs.
I believe the Crucial Memory is much better than those that come with DELL,.
Heard that the PC will utilize the sticks of memory closest to the CPU first, is that true ?
If it is , then I would like pull out the 2 sticks that comes with DELL,and stick those in third and fourth slots [ comes with 4 slots a MAX of 32 Gigs ]
OR it does not matter?
2 major things you have to look at are, firstly: Make sure the desktop does support DDR4 memory, if it only has DDR3 in it, DDR4 wont work in it and be supported. Secondly different RAM has different timings and voltage settings. More then likely you wont be able to mix and match the two sets of ram because they will both run off different settings. You need all the sticks to have the same settings, (this can happen, for different makes of ram, and have the same settings, but unlikely)… (Technically you can do this, but it will run at the speed of the slower RAM or in same cases not identify one of the sets..)
I am unsure, but dont think the speed will be affected. But there is a chance they are dual chan memory slots, so you actually need to have sets of two and the sets will be different coloured to make sure you match them correctly..
Edit: had a look for you, It does support DDR4, isnt dual chan so having pairs isnt needed, so thats fine, just gotta check timings and voltage settings between the sets you will receive…

It is a Desktop, and crucial Website matches the the particular brand, and model. I guess “most people” , if they have to Upgrade and add xtra RAM, should be able to just add more RAM, as long as they are ” Compatable ” that is why, most Memory places that sell RAM, have a Scanner, you can download to scan your system first
or selector to ask : what manufacturer,what product line and what model

That crucial memory looks like good stuff.
You could always do a memory benchmark test with Aida64 to see if one combination runs faster than another..
You should be up towards the top of the chart
The ram is dual chan. Put the Crucial in the slots with the white lock tabs and the original in the other two(preferred). All the info needed is on the Dell Site.

Sort of – if you only have two sticks then some computer motherboards prefer them in the first two slots.
But, to answer your question… Whatever ram you have:
The slowest, “worst” speed will define the WHOLE of the ram – so if you have 2 x 1666 and 2 x 1333 then you end up with 4 x 1333.
Whether that matter is another issue.
If you have 2x2G high speed and move up to 2×2 plus 2×4 (lower speed) (12 total) then the move from 2 gig to 12 gig will provide a greater boost than the loss of speed will cripple it.
If you have 2 x 8 gig high speed and add 2 x 8 gig (32 gig total) low speed then the loss of speed will cripple more than the move from 16 to 32 will help.
*****
OK – now… if the 16 gig is so much better (and it looks as if it is), run that 16 gig on its own and maybe buy another set later on – give the 2 x 4 gig sticks away or sell them.
Will be getting a DELL XPS 8900 Desktop,
“Will be getting”??? – then specify that you want it with the full 24 or 32 gig of the crucial ram. Dump their 8 gig before you even get it = no wastage, no “give it away”..

Just got it today,and I ran a compatability Test using their Sxcanner and the xtra Memory I ordered from another place are the Right one,you don’t think I can utilize the Original [ 2 X 4 ] -8 Gigs in the 3rd & 4th Slots?
– thinking it might slow down my Comp or give me problems down the line?
I think you’ll be able to without problems.
the memory they have in it originally must be the same basic memory type as your new stuff.
The speed issue MIGHT still be there – if the original memory was slower then it will make the computer access all memory at the lowest speed.
The reality is that it probably won’t matter – you MIGHT notice the speed difference in benchmarks and tests… but for general use? Probably not.

Think the speed is the same:

Coded for you this time

In that case all will be fine.
1] The original memory has to fit the computer properly
2] The new memory, you checked, does.
3] the speeds are the same.
1 + 2 +3 = 6 (equals “go ahead, mate, it’ll be fine).

Thanks Mate for the assurance- cheers!
2 + 3 + 4 = ?? << depends whether I’m drunk or not – LOL
