Many questions about RAM: 1 Can RAM chips be moved from one stick to another? 2. How can you determine that the landing of the chips are the same without soldering?

Question

Iron

1. Can RAM chips be moved from one stick to another? (provided that the seats match?) Or, in other words, the RAM bar is just a board that connects the DRAM chips to the motherboard chipset without any tricks (if we talk about PC-shnuyu)?
2. How can you determine that the landing of the chips are the same without soldering? Let's say if the memory chips have the same manufacturer and the same type (ddr2 ddr3), then can we say that most likely the seats for such chips will be the same?
3. Why does fbdimm ddr2 get so hot? Or what exactly is heated in fbdimm ddr2? All elements or just uh... "processor"?
4.What is the difference between fbdimm and dimm? There the only difference is that everything works through the "processor" and all other elements are the same as on dimm?

Answer 1

you can, BUT!! in addition to the seat, the pinout of the chip must match - i.e. to which leg which logical output is connected.
If you confuse data outputs with address outputs, it will not work.
But if you confuse the signal and power outputs - you'll burn the hell out :)
plus you also need to remember about command systems - a DDR2 chip will not work with a DDR3 bus.
Jambs will be if the operating frequencies of the chip do not match the frequencies wired in the SPD - a small flash drive in which the parameters of this memory bar are recorded.
etc. etc.
so read the datasheets for specific microcircuits, there should be full information about them.

Answer 2

2. Datashit download essno. Look at the name on the chip, find the manufacturer's website, download the datasheet.

Answer 3

Go to a site with fonts and a simple review of all the decorations you will find on page 20-30 for sure if there is one.
