Question Corsair Vengeance 2 x 32gb + 2 x 32gb ?

[i34]

Hi, I did an upgrade to 14700k system and didn't afford the 128gb jump I was planning. Now I am in a position but I want to know what best to add on.

I have 2 Corsair V 32GB sat at 6000mhz and wonder what my options are. I can save a lot by getting two 5600mhz and think that will bring my other two down to 5600 too. I don't mind. I can get some 6400 slightly cheaper then the 6000s I see that are more expensive now than when I bought them new.

But then I am asked by my friend if 128gb is overkill.

If you buy anouther set of 2X32gb and they don't work with what you have then your right back where you started but spent money.

Safest thing is to buy a 4 X 32gb set and sell what you have.

Are you using all the ram you have now?

I can't afford to do that.

Bob. Hi, I doubt it but the deal I am getting, I can't lose money if I decide to resell on so it's gonna be cool to try.

Thanks for fast replies !

You might have to swap the pairs of DIMMs over on the mobo, before the BIOS reads the slower DIMM timings from SPD and sets 5600MT/s for all four DIMMs, instead of 6000MT/s.

You may have to drop the speed even lower than 5600MT/s to obtain stabliity.

Four DIMMs place a bigger load on the CPU's IMC channels and you may find the system needs to be run closer to 5000MT/s or even 4800MT/s.

Getting a kit of 4 identical DIMMs (purchased as a single kit of 4) to run at fast XMP settings can be more challenging than a kit of 2 DIMMs.

Getting two kits of 2 DIMMs (with identical part numbers) can be more problematic, because you don't know if the memory chips and timings will be identical in the two pairs.

Getting two kits of DIMMs with different speeds to work (as you're intending) increases the risk of instability/incompatibility still further.

I prefer to fit only 2 DIMMs when possible, but I have some rigs with 4 DIMMs. I usually run 4 DIMMs at JEDEC default, e.g. DDR4-2133 and DDR5-4800, rather than at high XMP speeds.

Does your workload really require 128GB of ram?
What do you use your pc for?

To assess your need for more than the 64gb that you now have, activate task manager performance tab.
open the resource manager and look at the memory tab.
Look at the hard fault rate when your heaviest apps are all running.
If you see a hard fault rate of much more than zero, you could use more ram.
A hard fault happens when a needed page is not resident and windows must fetch it from the page file.
Your app stops dead during that process.

Ram is sold in kits for a reason.
A motherboard must manage all the ram using the same specs of voltage, cas and speed.
The internal workings are designed for the capacity of the kit.
Ram from the same vendor and part number can be made up of differing manufacturing components over time.
Some motherboards, can be very sensitive to this.
This is more difficult when more sticks are involved.
Ram must be matched for proper operation.

You can sometimes compensate for errors by increasing the ram voltage in the motherboard bios if you have a motherboard that permits such settings.
