DDR3 in DDR4 Slot

[iKingRPG]

 Okay, okay. I know that is a big no no, and many people buy the wrong RAM by accident. But DDR3 is cheaper. And for people that don't need speeds from DDR4, they are forced to upgrade in order to have a motherboard compatible with new CPUs and other components. But -- is it actually possible? that is the real question. I know the short answer is obvious, but is there actually a way?

 

 I find that since I, don't personally need the speeds, I want to be able to buy a good modern motherboard, and not have to worry about finding a pot of gold in order to have more than 4 GB of RAM for my editing and gaming.

Hopefully you guys understand!

Note: I don't know alot about overclocking ram, or why it is a thing, but idk if i can change some software thing to change the ram type to make it compatable. Can't really find anything on this, and assuming u can't do anything to make it work. It's ok either way.

they are electrically uncompatible

no hence why the slots are not the same slot. Not to mention the memory and controllers being totally different.

 

 

[IgorM]

also size and number of pins is different

[Belzebuth]

You could buy second hand DDR4, it's the only "cheap" way

I didn't mention, I have seen adapters online, but from what i have read, all they do is make them physically fit. I don't really know about frequency and stuff a lot.....

True. I was just curious if there was a way because I am only 13, therefore I'm not the wealthiest. The cheap way is kind of where I was aiming in this post.

I am aware. I was just wondering because RAM isn't cheap.... I could also just buy used laptops online and take out ram and buy adapters like Linus did in one video. Some people who sell used stuff have no idea what the value is in the inside.... That is one way to get cheap DDR4 instead I guess.

Different voltage, your CPU will be fried

i know, but i just thought maybe i could force it to work by programming something.

Let's completely ignore the IMC limitations and massive difference inner timings between the two, and focus strictly on electrical signals and physical pinouts of the two types of DIMM's. 

 

DDR3:

 

 

DDR4:

 

Ignoring the fact that you would somehow need to account for the lack of those missing 48 pins, you would also need to completely reassign the function of the pins themselves, and alter the trace topology of the DIMM's to account for that change in signal. You would need to first get by this physical limitation before you could even address the aforementioned issues with the IMC and vastly different timing configurations.

The CPU itself would likely be fine (assuming you are referring to VDIMM and not VCCIO/SA), but the board might not have a good time, lol.

Well i thought because I have seen wall adapters that change voltage from like american cable to european wall outlet.

IMC?

Just save up a little more money and do it properly. Oy.

Thanks for that. I just lost some hope, and at the same time am happy for your answer... Thanks for the better understanding.

Yeah good idea. Especially after seeing MageTank's post. Thanks guys. Let me know if there is a cheap way that will work properly. Thanks again.

That would be the VCCIO/SA voltages I referred to. I thought you were referring to VDIMM when you told him "different voltages", because VDIMM is the only advertised voltage on memory.

DDR3 in one of those weird B150 boards 

[iKingRPG]

I just took 4gb out of my 12gb laptop to add to my desktop pc after i buy an adapter. My laptop is a HP 15-bs033cl and i use it lightly for document editing and other lightweight software. Hopefully this works like it did for Linus in his video. The items on ebay look a little sketchy. Have high shipping costs too.

if you dont care about speed why not use virtual memory sure it wont give you the performance but if you really need it that's an option

They could've just gotten an electrical adapter.

[NumLock21]

Just buy some DDR4 ram, with your trying to "save" and yet getting them adapters defeats the purpose of saving.

as said before you can buy from ebay for lower prices. Ram prices went up beacause of nand chip shortage

probably way more expensive than just buying the ram itself. not worth it

[asand1]

You know what, bacon is even cheaper than DDR3, maybe you could make bacon work? Or cardboard, could you program the CPU and motherboard for cardboard compatibility? While your at it, maybe you could make your mums Saab run on maple syrup.

Good idea. I'll try that!!!!

Well believe it or not, ive seen laptops that came out last year on eBay for $10 US dollars because they think it is trash since they broke their screen or something. I have even seen potato pcs like those from HP where 12gb of ddr4 is standard. Also desktop computers are they same kind of thing. I guess your right though, so I just gotta pay for ddr4. and there is no good way out of it. that was the point of this post.
