SODIMM memory question.

idainc · Feb 19, 2025

I bought two sticks of Corsair Vengeance DDR4-3200 16gb. I ran CPUID and although thte specs on each are identical one report says one stick has chips made by Hynix and the other was Micron. I'm not experiencing any problems. Amazon sells these individually for $25.99 each or a set of two for for something like $62.99. I ordered 2 of the lower price.

Does the higher price pair imply that the chips are form the same mfgr ?

To enable dual channel RAM, purchase RAMs with identical chip specs.

CPU Z reports: Looks like I'm not running dual channel. I;m wondering if I;d see any significant increase if I bought the set for $62.99 ?

You will have more bandwidth with dual channel configuration.

According to CPU Z they now express dual channel mempry as 2x64 so I'm good. Thanks.

You are very welcome!

Paired devices are generally tested and closer matched in performance that random picks.

For dual channel you should be buying memory modules in a set/kit of 2. Such modules will be from the same manufacturer and the same Month/Date, production batch.

The difference in cost is normally small, Corsair are overcharging.

2 Individual modules from different manufacturers will not be closely matched.

In this case both modules are from Corsair but the individual chips are from different manufacturers. HW INFO reports they are identical and I am running Dual Channel. And they are overcharging seemingly on the basis that people will think they are matched when in fact they already are.

I posed the question to Corsair and received this reply -

"However it is not advised to use multiple kits. Using multiple kits in a single system is not a supported or guaranteed configuration as it can cause issues such as system stability problems, prevent XMP/DOCP from working correctly, or even prevent your system from booting. Our DRAM kits are only validated and guaranteed to work in the configuration they are packaged and sold as. "

I bought a matched set of Crucial on Amazon for $56.

I took a different path and ordered a set of two Crucial sticks which only use Micron chips and installed them. There is a notable increase in what I'll call perceived speed. I cant quantify it but I notice an increase in speed. Likely largely due to there being two GPU's. The Intel 770 uses shared memory and the Nvidia uses its own so apparently a matched set of ram enhances Intel 770 use.
