Mix and Match RAM‽‽

[CosmicGamerGeek]

Hey, Good Folks of LTT Forum, 

 

How are you all doing?

 

I am new to the forum and I had a question regarding upgrading my PC Ram. 

 

In my System, I currently have 2 sticks of 4 Gig each of Crucial CT4G4DFS824A running at 2400 MHz. For Refrence

 

My Question is, Can I add 2 more sticks of Crucial CT8G4DFS824A which I believe is the same stick of ram with 8 Gig instead of 4 For Reference

 

Will this pose any compatibility issues? Since both the ram seems to be exactly identical except for the memory size. 

 

Looking forward to hearing your thoughts. Any help is greatly appreciated.

It wont be running in dualchannel. And therefore isnt recommended

[LukeSavenije]

it could cause comparability issues

 

it could work just fine

 

welcome to memory comparability land

wouldn't it run in double dual channel?

I think so. I will say im not 100% on that one

 

Edit: no it wont. You will get faster than singlechannel, but not dualchannel.

If put in right slots it should still work dual channel. I'd rate it as unlikely to be a problem especially given the low speed.

Some More Info - 

 

MoBo - B450 Pro VDH AM4 

CPU - R3 1300X

 

Current memory config - 2X2 in dual channel 4 gig each 

Total Ram Slots - 4 

Total empty Ram slots 2 (1 in Channel A and 1 in Channel B) 

 

My thoughts - Since the ram is essentially the exact 1:1 make except for the size of memory, in theory it should work perfectly fine.

In theory ... but RAM land is a speculation cookie

So what do you suggest? Do I take the risk or Do I stick with what I have and buy more of it

I would suggest selling your current ram and buying a 16GB set or 32GB depending on how much you need OR buying a second 2*4GB ram.

Selling is completely out of question. The used market scene in India is essential non existent especially where I live. Maybe 2 more of the same 4 gig each is what I should get. Thanks for the help.

in therory... Ram compatibility is prob the worst thing in pc building, you realy jsut need to trying it and return it if i does not work, thats really your only option

I've done a similar thing, but on my case i purchased a two year old DDR4 2x4 RAM sticks, which has the exact specs (timings, capacity, speed) on my current sticks. Also, they are different units from GSkills, RipJaw V (2x4) and Aegis (2x4). It work perfectly fine and my PC immediately read the added sticks.

 

what i understood on dual and quad channel memory, is that if your motherboard supports on either of those, it is recommended to run on those configuration and your sticks that you purchased should match your mobo channel. Example, if your mobo has 4 ram slots but only runs at dual channel, you should use a RAM kit that has two stick as it will run at dual channel. This is also the same as quad channel, you should use a kit that has 4 sticks on it.

 

Now for your question, if you're going to add TWO more sticks (2x8) on your current set up, you need to check if the timings on all sticks are match (like 15-15-15-38). yes you can use 2x8 with 2x4 (a total of 24gb). And as i mentioned earlier, if your mobo is a dual channel config, you can use another kit with 2 sticks on it on to your mobo, but it should have the same speed and timings, and most importantly, runs at dual channel memory.

 

but you have another option, just buy another kit that has the same specs with your current sticks to make sure that there will be no problems. You will instead have 16gb vs 24gb, and i think 16gb is pretty much enough if you'll only play games and browse internet. 

 

Heyy LTT forum folks, just correct my statement if you found any inconsistencies with it. thanks!

India doesn't have consumer friendly return policies. Here it's you buy it you own it, once sold we don't give a
