I have a Dell Precision T3620 with a Intel Core i7 7700K CPU. This computer can handle up to 64GB of DDR4 RAM. It came with 32GB (4 sticks of 8GB Kingston HP24D4U7S8MD-8 RAM) installed. I want to upgrade to 64GB.

In the past, I have usually bought Crucial RAM. Crucial has a compatibility calculator on its website that can be used to find compatible RAM for each model of computer.

Here are the results for my computer model:

https://www.crucial.com/compatible-upgrade-for/dell/precision-workstation-3620

It found that CT2K16G4DFRA32A (a kit of two 16GB sticks, of which I would need to buy two in order to get 64GB) was compatible.

Here's the Amazon page for this kit:


On the Amazon page above, I noticed that there was a message saying "there is a newer version of this item", which linked to Crucial's CP2K16G4DFRA32A kit:


CP2K16G4DFRA32A RAM has a heat spreader and is cheaper for some reason. I'm not entirely sure whether it's better or worse than the CT2K16G4DFRA32A, or whether it's compatible with my computer (as it doesn't show up on Crucial's website when I search for RAM compatible with my computer).

Which one of these options would be better?

Also, are there any options from other brands that are either better, or just as good but with a lower price?

Why are you upgrading the ram? The Precision range of prebuilts were made as workstation machines...so they usually came with ECC ram. The ram you're looking at are non-ECC. If you need the ram for capacity and don't need ECC on it, then any ram off the shelf so long as it conforms to your motherboard's ram slots, i.e, DDR4.

Just an FYUI, the max ram speed your motherboard will see is DDR4-2400MHz;

So if you can hunt down a DDR4-2400MHz 4x16GB kit with tight latencies, that'd help you the most. You can drop in higher speed ram but they will be downclocked to DDR4-2400MHz due to your integrated memory controller and motherboard chipset's limitations.

Why are you upgrading the ram?

Because I only have 32GB and I want 64GB. Some of my programs aren't working well because they need more RAM, and my computer is getting sluggish at times due to the heavy RAM usage.

So if you can hunt down a DDR4-2400MHz 4x16GB kit with tight latencies, that'd help you the most. You can drop in higher speed ram but they will be downclocked to DDR4-2400MHz due to your integrated memory controller and motherboard chipset's limitations.

How do I determine if a type of RAM has a tight latency?
