Question 128G DDR5 3600Mhz Ram

[Victory Pete]

I bought a Dell XPS 8950 and was surprised to see it came with the slower 3600Mhz Ram. 64G and 32G come with 4400Mhz. Why is this?

You might need to go to bios and boost it to that speed also go on dell website and contact them if something is not right!

I talked to Dell Support, they told me I had to return the computer and reorder if I wanted faster Ram. I am not sure what to do now
I am going to try to sell what I have now.

faster ram cost more.

Is 128GB of DDR5 3600Mhz better than 64GB at 4400Mhz?

 

[rgd1101]

depend on your ram usage.

128Gb is a massive amount of ram for the memory controller to deal with. 4x sticks and high speeds. 3600MHz might look slow on paper, but you'll not really see any difference to 4400MHz. The slower ram has tighter timings, which is just as important to Intels as higher speeds, which makes up for a lot. 3200/14 is the same (realistically) as 3600/16 etc as far as info in-info out times.

128Gb is workhorse amounts, 32Gb is racehorse. Big difference. Slower ram is also far less prone to errors, bit-flips etc, so is more reliable for large data use, which is what 128Gb is intended for.

Probably related to how often you use the 65th GB of RAM, considering that the alternative would be a relatively slow disk of some type.

Do you use it 1000 times per second or once every 3 weeks?

 

[Victory Pete]

I would love to just leave this issue as is, trying to return the PC and getting 64GB at 4400Mhz would be hassle.

 

[Victory Pete]

One thing I am aware of is that DDR5 will get better in 2 years, so I will be throwing away more money if I am replacing 128G vs. stock 64G.

Maybe not so much. You'll get a years or more use from it, then sell it at @ 3/4 price of new. Ppl will buy 128Gb at a reduced rate if it's relatively new and cheaper. It's hard to get DDR5 at any speed for a reasonable price atm. That'll offset any cost of 64Gb new, shipping ram is Far easier and faster than waiting on a pc turn-around time and shipping costs in money/time.

And you'll get the ram you really want, like Crucial Max 5100MHz and nice 19 Cas timing etc.

Plus, after a years worth of use, you'll be able to purposely monitor ram usage, do you really need 128Gb or even 64Gb, as well as giving DDR5 time to mature.

This makes sense, thanks.

Are you sure the ram is ddr5?

Yes, I think..... I am trying to post a picture here

Looking closely at my picture it says 4800B on the label, could that mean 4800Mhz?

Wow, these 32GB X 4 sticks are in fact 4800Mhz. I did some surfing. Good thing I didn't start returning the PC or buying more Ram

Maybe Dell has them tweaked down?

DDR5 standard is 4800 to 7200.
Dell probably bought memory that would not meet this and had the company down clock it to a stable speed massive amounts of sticks.

Dell saves a bunch of money and the company doesn't have a lot of memory they can't sell.

I don't see that happening, apparently there are settings in the PC's BIOS that can change the speed.

All I can go buy is what you said, I'm not at your house and have no clue what your looking at.

Post a screenshot of task manager/perf/mem.

Post a screenshot of task manager/perf/mem.

It shows 3600Mhz just like I expected it would. I am going to try to open the BIOS and have a look
