Black capacitors in a RAM stick, are they all the same?

[TheNaitsyrk]

Hello there.

 

I recently purchased DDR5 8000Mhz, and took heatsinks off my RAM for water cooling purposes.

 

That's not important however, what is important is that I accidentally took off one of the microscopic capacitors next to the RGB light.

 

I bought USB microscope and proper soldering iron and managed to solder a capacitor however, not the original one from the ram it came out of.

 

I de-soldered exact same looking capacitor from DDR3 RAM and soldered it to my DDR5. When looking at the RAM it looks like before, same size capacitor. Tiny and black.

 

Do they all do the same thing? Would capacitor on DDR3 be better due to higher voltages being run?

 

Here are the pictures.

 

The green picture shows the cap I took and reattached to black ram which is the DDR5.

 

I don't have 13900KS yet of course, so all I could check the ram with I'd G6900 I had and RAM boots up, and allows for XMP 8000.

 

Will this be all good?

Black is a resistor, not a capacitor. Tan/grey are capacitors.

 

A cap or resistor of this type could be virtually any value within a wide range, they all use the same standardized package sizes.

Thank you! I'm not super knowledgeable about this so I thought I'd ask.

 

If I understand correctly, this resistor may not be a good fit?

I'm also assuming that resistor is used for the RGB light as it goes directly to it as looking at the trace right?

I would not assume so unless having it in hand to test for continuity. Getting the wrong resistor can be dangerous. Either it works, it works for a while and pops off or something burns. If it is just the RGB you should be ok. 

I'd look at high res images of the memory in question and then order the resistors online. They are very inexpensive. We are talking cents per unit.

 

Btw. and I know that is none of my business but RAM cooling is not necessary unless you OC that thing, which is unlikely as you have already bought memory that is over spec by a lot. You probably should adjust the processor to sync with the RAM's frequency. I haven't even seen DDR5 over 7800 yet, nice latency though.

I will be overclocking it to the brim, like a lot. I have dedicated loop for just RAM (I know Insane, but my build is all overkill).

 

I have bought a cheap multi meter and will check resistance in Ohms to see if it's close or the same to the original stick.

 

I have asked on Reddit as well and that's what I've been told I should try.

I also turned on the PC with that transplanted resistor and all seems fine. I haven't turned XMP or have been to Windows but BIOS shows 8000 XMP and 32GB of RAM detected fine.

no such thing.....lies...all lies.... 

 

If it works and detects just fine I guess it will be ok. But as I've mentioned above, you will have to adjust the processor as well to really make use of the faster memory speed. Otherwise it may end up hurting the performance.

I know what I'm doing no sweat haha.

 

I'll measure resistance in Ohms to make sure it's all the same (or close) and if it is I'll slap water block on those bad bois

Okay so I re-soldered it. Not the original resistor because I broke it, but I measured with multi meter and the original one says 0.29Ohm when I measured at 20K Ohms setting. The new replaced one in the other stick says 0.29Ohm.

 

Will that be good enough?

 

I also assume it's for the lighting as trace goes directly to the RGB diode.

 

Put them in the PC and all the lights work and XMP setting is available in BIOS as well as the correct ram capacity.

Sounds good.

Sorry, I did a typo there. Original one is 0.29Ohm but the new one is 0.24Ohm.

 

Phone auto corrected...

 

Is it still okay?

 

Difference of 0.05Ohm.

 

Touching the leads together from the multi meter is like 0.02Ohm.
