Need help, choosing what DRAM to buy for my desktop

Ok, currently I have the following RAM installed in my desktop. The brand installed is XPG ADATA . My head is spinning, trying to figure out exactly what to buy to upgrade; not only brand, but specific model, etc.... I would really appreciate some advice! NC

Attachment 83487

Memory Type	DDR4
Memory Size	16 GBytes
Channels	Dual
Memory Frequency	1332.1 MHz (1:20)
CAS# latency (CL)	19.0
RAS# to CAS# delay (tRCD)	19
RAS# Precharge (tRP)	19
Cycle Time (tRAS)	43
Row Refresh Cycle Time (tRFC)	467
Command Rate (CR)	2T
Uncore Frequency	4199.0 MHz
Host Bridge	0x3EC2

Selecting the brand and type of RAM to buy is directly related to your CPU and motherboard Chief.

Could you tell us:

• The motherboard you want to install it on
• brand and type of your CPU
• The amount of RAM you want to install

Cheers,

Priller

Also make sure you get the EXACTsame timings :

Channels	Dual
Memory Frequency	1332.1 MHz (1:20)
CAS# latency (CL)	19.0
RAS# to CAS# delay (tRCD)	19
RAS# Precharge (tRP)	19
Cycle Time (tRAS)	43
Row Refresh Cycle Time (tRFC)	467
Command Rate (CR)	2T
Uncore Frequency Make sure you put the new RAM in a "paired" slot that is paired to your current one. If it is 16GB in a single slot; buy a 'nutter 16 GB and put it into the correct "paired" slot. If you've got (2) 8 GB in (2) slots; get (2) 8 GB and put into the other (2) slots This is a weird format; how did I do that... all I did was copy& paste !	4199.0 MHz

First step, determine the manufacturer, model number, and revision of your motherboard. With that information, go to the motherboard manufacturer's website and look for a list or table of RAM that is certified to work with your motherboard. The speed of the RAM is not always the determining factor in how well it will perform. Tight latency timings sometimes makes slightly slower RAM respond and operate faster than fast RAM with high latency.

Thanks all!

Motherboard is a:

CPU is a:

Processor Intel(R) Core(TM) i7-8700K CPU @ 3.70GHz, 3696 Mhz, 6 Core(s), 12 Logical Processor(s)

Memory is:

16GB, and I would like to replace the existing DRAM and add additional memory for a total of 64GB (max for the motherboard)

Hi Chief,

I would go for this one. It's the fastes quality RAM that your MoBo will take:

https://www.corsair.com/ww/en/Catego...4GX4M2K4000C18

It's two sticks of 32 Gb. Should you need 4 sticks of 16 Gb, then it is this one:

https://www.corsair.com/ww/en/Catego...4GX4M4C3200C16 (but it is slower)

Cheers,

Priller

Thank you so much, Priller. I really appreciate your efforts to find that information. Now I need to decide which one! NC

My pleasure chief. The reason why I proposed the two is that I couldn't find out whether your motherboard would take sticks of 32 Gb. Sometimes there's not only the total capacity limit, but sometimes a limit to what every slot will take.

Intuitively though, I would go for the 2x32 GB solution as it is the fastest RAM of the two.

Any chance you could ask the guy who built your rig?

Cheers,

Priller

It is a company called IBUYPOWER, and from experience with having called them some time ago, they don't handle parts; just the entire system. My thought is to contact MSI (Micro-Star International) tomorrow, as they are the maker of the MB, along with Corsair, as I am sure they could provide answers? NC

Whoa! No one that I can find has the memory I want in stock! Crap! NC

This is crazy.

Would this work? Not what I really want, but am thinking perhaps it would be faster than what I have now?

or maybe this?

At this point, I am just throwing "darts", and hope something hits!

Welcome to the post-Covid world. Global semi-conductor shortage means things like memory are in short supply and when you find it, expect to pay more.
By the way, on many motherboards, 2 sticks of RAM is faster and more efficient than 4, but some motherboards are equally fast and efficient regardless of configuration.

You might as well go with Corsair Chief, pretty hard to go wrong and as pointed out above, everything is hard to buy thanks to COVID.
:encouragement:

I went ahead and got this for now. Last night, it was on Best Buy for $199.00. This morning, it went up to $224! It is NOT the fastest of drives, but is one heckuva deal for the price!

Thanks for that info! I had read that earlier, and ordered this from Amazon:
https://www.amazon.com/dp/B07WQ447MN...ing=UTF8&psc=1

It will fit into my one remaining PCI-E slot, and allow me to use the ssd card. I plan to back up my C:, then install another ssd card in the dedicated M.2. Slot, and install files back to that. NC
