New RAM Question

[Sniper Charlie]

I just bought new RAM and was wondering if theres anything more I need to do.
My specs
Windows 10 64Bit
AMD Radeon R9 Fury X
Intel Core i7-5820K 3.3GHz
16GB RAM Corsair Vengence LPX 3.0GHz

I have an older Alienware Area 51 R2 (late 2014), with the X99 chip, and although this RAM is compatible, and I turned XMP on in the BIOS, it went to 2400 speed. Thats all auto tuning, I didnt do anything else. I dont OC, so is this good enough? I looked at the manual clocks, and all it had was 2.666GHz and then jumps to 3.2GHz, no 3.0GHz.

I dont feel confident in knowing what Im doing with manual set up and overclocking, so I left it all alone, but I just wanted to make sure, am I missing out? or will this be ok for now.

Thanks.

I think you’ll be alright concerning RAM speed.

If you want better performance overclock that 5820k, these X99 chips are not all that great for gaming unless overclocked.

The 5820k is a great overclocker, it should easily be able to do at least 4.3Ghz.

Thanks for the input. Im kinda bummed now. Looks like my XMP is freezing my computer. It was working just fine! I turned my computer off like normal to take a break, booted back up, got a black screen, had to turn off manually. Then, booted to the Windows 'Please Wait" with the dots rotating, then it froze. Turned off XMP, boots right up. Im sad now, thought I was gonna be able to enable this XMP and take advantage of the faster RAM.

I think I just found my own answer. This Haswell X99 chip from Intel supports up to 2133GHz memory, and does not support ECC memory either. I guess I will keep the RAM, but this is what I get for a pre-built. Aghhhhhh!

2133mhz is what its guaranteed to work with, anything more is considered an overclock and isnt guaranteed to work.

Now i had a 5820k that ran at 4.6ghz, and 4 sticks of 2666mhz ram which was overclocked to 2933mhz, worked flawless.

Im now on a i7 5960x with 8 sticks of 2666mhz memory thats at 2800mhz, 8 sticks are harder to get stable.

Memory speeds on x99 chips dont make a huge difference in performace, you definently get more noticable gains overclocking the cpu then you do ram.

Thats some serious OCing. I have no clue when it comes to that stuff. I will just play it safe and leave XMP off for now.

I do have another question if anyone can answer. Does it matter what DIMM slot I put the RAM in on my motherboard? Currently they sit in DIMM 2 and DIMM 4. Not sure if that changes anything.

Thanks again.

I had this PC breifly yes it does matter what slot you put your RAM in (unless you mixing RAM (I did have issue mixing RAM with Dells RAM FYI), and 4.3 for that OEM AIO cooler will not work don't OC it to 4.3 ,3.8 was highest that cooler can handle.

Here is my modfiication post I did on this PC if you interested

Be happy it runs at all, dells can be rather picky with ram.

Def not mixing RAM. I bought new sticks. 2 8GB sticks for 16GB total. So what slots are supposed to be good? I have 4.

------------------------------------- DIMM 1
------------------------------------- DIMM 2


------------------------------------- DIMM 4
------------------------------------- DIMM 3

Kinda goofy set up by them but whatever. Thanks for any suggestion.

use the same colored slots

Unfortunately that is impossible seeing that they are all the same color.

oh, the 5820k is x99
supports quad ch ram, so use any 2 slots for dual ch mode

[Sniper Charlie]

Thanks for that. Always wondered that now a days. I do remember when I built my PCs, the color RAM slots. With this Alienware, they had the old RAM in slots 1 and 2. I panicked for a bit, then did the whole 1 - 3 or 2 - 4 combo.

You only got 4 slots on that board, If you have 2 sticks, you want both the sticks on the left side of the CPU socket for dual channel, Having the sticks on the right side of the CPU should also work, but may not run in dual channel and hinder performance some if the system even boots like that.

On that board to get quad channel you will have to fill up all the slots with ram.
