Reason for Sale
Would like to upgrade to 8GB
Hey there.
I pulled out my old Dell’s RAM and I’m open to sale but would much prefer a trade. It’s a 4GB laptop stick but I couldn’t quite make out what speed. I think it’s 1280Mhz but correct me if I’m wrong.

Like I said, I’d much prefer a trade for a single 8GB LDDR3 stick for similar speed (RIP dual channel) but I’m open to selling it for around 1200. Saw 8GB sticks for sale (used) around 1500 so I’m willing to pay upto 300 INR extra for trade.

If you’re interested, feel free to let me know and I’ll get back to you at the earliest!

Just for information, that's a low voltage (L) DDR3 1600 RAM. The actual clock speed is 800 MHz but since it's DDR (Double Data Rate), it works at twice the clock frequency and is often specified as 1600 MHz. This is technically incorrect but is accepted in a casual description.

So it's technically 1600Mhz but works at 800Mhz? Should I change my post then? I am clueless when it comes to RAM.

It's technically 800 MHz but works as if it's 1600 MHz. (All DDR RAMs - DDR1 to DDR6 - work at twice the clock frequency). You can just call it DDR3L-1600 without the MHz term. Many people call it 1600 MHz including sellers here. It's no big deal and most people will understand.

To expand a bit, the timing clock provides millions of pulses per second (MHz). All pre-DDR RAMs process data once per pulse, but DDRs process data when each pulse is starting and when it is ending. So they effectively work at twice the clock frequency.

The L stands for 'low voltage'. Non-L RAMs need 1.5V whereas L RAMs work at lower voltages like 1.35V, 1.28V, etc.
Oh ok. Is there a tool like CPU Z for RAM?
CPU-Z itself provides all the info that most end users will need to know about their RAMs. There are two tabs for that.

The 'Memory' tab will show you the actual frequency, latency, etc it is currently running at. This is not necessarily the maximum speed it can do.
The SPD tab will show what each RAM stick in each slot is capable of. The maximum speed shown is not necessarily the one it is currently running at.

Well, today I learnt. Thanks for clarifying! :)

How to find if the one in this listing is 1.35v or 1.28v, as I want to upgrade ram in my Synology & this is the one synology recommends:

About a third of the way down on that page, it says 1.35V under "Technical Details"
Also, at the top to the right of the image, there's a link called "Make sure this fits". This brings up a list of compatible systems.
You can also see what Synology says about it at https://www.synology.com/en-in/products/DDR3

=======================================================================
It seems a few people are interested in what I said earlier. To put what CPU-Z shows in a more succinct way -
The SPD tab shows what the RAM stick can do (if you have more than one stick installed, be sure to select the one you want to check at the top left)
The Memory tab tells you what it is doing.

Thank you for the clarification.

I see the Synology needs 1.35v but I wanted to know if the ONE that OP listed is 1.35v or something else.

Here are the pictures from CPU-Z. Got both Memory and SPD tab screenshots.

If there are any more photos that you require, please lemme know and I'll get back to y'all ASAP. Have a good day!
Deal agreed with @Pimpom if I can’t find a trade deal. Prioritising trade over sale. Same has been made clear with buyer. Will leave it up for like two weeks. Thanks!

Yes. After trying to help by clarifying some technical points, I remembered that my daughter's old laptop could use some additional RAM.
