I have currently saved some money and want to give my gaming PC a bit more ram, since I like to get 95% ram load on games like Minecraft or Fortnite.
I currently have 2x 4GB Corsair Vengeance DDR3 ram with 1600mHz and now want to get the same model with 1x 8GB and 1600mHz (https://www.amazon.de/gp/product/B0085IZRSO/ because the 4th slot is somewhat covered by the CPU cooler.
I know a lot about PCs, but still wanted to ask if I should do it and if it could not lead to errors…
That should work flawlessly since they clock on the same mHz number. What kind of graphics card do you currently have?
Should work. Just make sure you pack the two 4 GB modules in slots 1 and 2 and the 8 GB module in slot 3.
Jo I wanted to do that anyway. So the 2 4GB bars in the blue slots and the one 8GB in a black slot so that the 2 4GB bars already run in the dual channel right?
So that you can use your entire 16 GB in dual-channel.
It works, but ideally there should be the same amount of memory on each channel.
Say retrofitting 2 4GB modules is better than an 8GB module.
In your current configuration you would have 12GB on one channel and 4GB on the other. This can have the consequence that the upper memory area above 8GB can only be operated in single channel.
Of course, the operating system optimizes the whole thing but better would be the same amount of memory on the channels.
You would also have to make sure that the latencies are the same, otherwise the new RAM may slow down the others. Since the new Ram is from the same manufacturer and is actually the same model with more memory, I assume that the latencies will be the same.
I think the 8GB bar can't be used in the dual channel. Only the lower 8GB segment can be used in the dual channel. The 8GB additionally hang only on one channel and are either connected to 1 or 2. Which results in different memory sizes on the channels.
On most reasonably modern boards, it is irrelevant for the "dual channel mode" whether the 1 × 8 GB is then on Channel A and 2 × 4 GB on Channel B if the board has only 4 memory slots.
Then the full 16 GB can still be controlled in DC mode.
Ok thanks for the helpful answer. Do I have to set the DC mode somehow?
A Palit GTX 1050ti 4GB
Oh yes, if that's how it fits.
I have assumed that the 8GB bar should be put on a channel on which one of the 4GB modules already hangs.
Then the division would be 12GB on the first and 4GB on the second.
But if you split the ram into 8 8 it fits.
A reasonably modern board can also be used with 8 + 4 in DC mode. There are only "hybrid" 8 GB in the DC, and the remaining 4 G only in the SC.
(8 GB on channel A and the 4 GB on channel B for hybrid DC set… Then the board or controller will only address 4 GB from the 8 GB bar to match the other channel for hybrid DC… Rest SC)
Graphics card is totally irrelevant in this question, since the RAM management of the mainboard and the graphics card have nothing to do directly with each other in relation to the question.
That's exactly what I meant in my original comment.
I just wanted to ask because a GPU upgrade would be helpful with e.g. A GTX 450, but a 1050ti is enough ^^
