Open the base up and look at the current module installed - take the specs of that module and pop on to Amazon to find another in the capacity you want.

Slide the new one in, close the base, problem solved.

8G is enough for few VMs. The i5 wont handle many of them anyway. It is a gaming laptop, there are better options when it comes to running VMs only.Also, you might be better off by just running them on AWS and GCP free tiers.


Your laptop comes with 2 DIMM slots with each loaded with 4GB stick. So you have to throw one away to upgrade from 8G to 12G

Not necessarily - this laptop could have a single 8GB stick. Only way to tell is to open the base.

so what do I do?
Do i just open the base find the spec info google it and make purchase? and replace it?

or should i get a professional to do this?
I have never done this before

You can do it yourself, I can send you few links to the Amazon. How much ram you think you need? Laptop you picked can take p to 16gb sticks, so i you buy one 16gb stick you will then have 20gb ram, that is definitely enough.

Checked where exactly..?

https://www.tomshardware.co.uk/dell-...iew-34422.html

"On our review unit, with 8GB of RAM, there was a free DIMM slot to allow you to upgrade to 16GB memory."

Clearly not every unit comes with 2x4GB.

EDIT: Even the Dell website states "8GB, 1x8GB, DDR4, 2666MHz" !!!

Yep, it's really easy - a few screws and it just pops open. If you have one stick in there, happy days! Buy another 8GB stick of the same type (and speed!), fit it, close the case, done.

If you have two sticks installed (which I have my doubts about...) then you'll need to decide how to proceed - probably buy two 8GB sticks and keep the others as spares. Same procedure applies.

Pre-sale review unit with similar specs for the US market is not the same what ends up as the cheapest offering in the UK Currys. Dell issues gaming laptops with both slots populated unless customer specifies otherwise. You lose performance by using a single stick, it also costs more. So the default is 2x 4G

Might be, it really depends on the version he is going to end up with. Dell G3 3000 3579 suppose to have both slots populated unless it is an Optane version.

The performance difference between running RAM in single channel vs dual channel is marginal enough not to notice in most cases. In terms of costs, a single 8GB stick is typically cheaper than 2x4GB. This makes sense, since the manufacturing process is simpler and fewer parts are required to produce a single stick vs 2 sticks. In terms of defaults, most manufacturers that offer dual SODIMM slots rather than soldered will populate one slot if possible so that you have the option to upgrade later. All round it simply makes more sense to use one DIMM.

With regards to your earlier post about 8GB of RAM being sufficient, that's difficult to say without knowing the use case. Even with just a handful of lightweight VMs you'd be cutting it close and ideally 16GB+ is what you want for moderate to high virtualisation workflows. The i5 8300H is also a pretty solid chip that won't have any issues with heavier virtualisation. The OP hasn't clarified what exactly they're doing with the laptop, but I find it pretty unlikely that they're going to run into bottlenecking issues as a result of the processor.

4G modules are currently lot cheaper per G when bought in bulk, they are essentially the previous generation of the main stream DIMM, as now the most produced ones are 8G, Laptop production is heavily cost optimised process, if they can save $3 on using 4gb dimms they will, and every point they can squeeze from benchmarks for free, definitely counts.

When it comes to non production VMs, CPU matters a lot, especially on laptop where you suppose to work and run those vms. Linux server than knows that it's running in vm can work with about 120mb ram. It's all about comfort, you have to be able to switch between IDE, multiple shells, pdf reader and Chrome in meaningful manner without freezing and lags or you get suicidal really quick He is clearly a beginner, so I guess it's going be one instance of Ubuntu and Windows Server 2016. 8gb is more than enough.

On the whole though, those few points in benchmarks will be within margin of error or outright won't show up. The quality of the CPU or the thermal paste application are going to be bigger factors. Most people simply can't tell the difference between single and dual channel. It's not nearly as big a deal as it used to be.

In terms of cost, I don't have any stats to verify that last gen 4GB modules are cheaper in bulk. But it's not relevant, the listing states that it's a DDR4 SODIMM module, so current gen. And looking at costs for brand new 4GB vs 8GB sticks, the pricing isn't linear. It's really not in the manufacturers interest to go for 2x4GB over 1x8GB. It takes twice as long to install 2 sticks vs 1 stick and they'll outright lose sales from people who wanted the option to simply add another stick. And as IWMTom points out, the manufacturer site specifies a single 8GB stick.

The CPU is literally not an issue. I can run multiple VMs on an 8250U (a low power chip) just fine. The 8300H is likely to be fine for their VMs. It's unreasonable to conclude they're a beginner and what matters more is what they're actually using the VMs for, which we don't know at this time. 8GB is absolutely fine as a starting point, but without knowing for sure we can't verify. 8GB is alright for light virtualisation, but 16GB is usually the sweet spot. And TBH, I'd be inclined to upgrade the RAM anyway, purely to ensure there's no need to start paging files. The disk is most likely to be the number one bottleneck here, so avoiding further disk usage because you ran out of RAM is ideal. Necessary? Probably not. Nice to have? Certainly. There's no good reason to stick at 8GB besides the small saving of ~£40.
