RAM: Two RAMs not working together

Sun, 01 Feb 2026 12:52:28 -0700

So my two DDR4 RAM which are same in everything, used to work together before, but all of a sudden they are not working together.

The RAMs do work individually but don’t work together, they both are 8GB.

I know that the slots are working as I tried changing them and putting them together.

RAM: Identify damaged SMD components on DDR3 SDRAM module

Fri, 26 Sep 2014 03:51:33 -0700

I have a G.Skill Ripjaws 4GB 240-Pin DDR3 SDRAM module (F3-10666CL9D-8GBRL).

I managed to damage/break off some of the SMD components near the pins on a DDR3 SDRAM module. The rest of the module is fine, so it would be a waste to throw it away because a few components got knocked off.

Here are a couple of pictures of the damaged module and a working module. The first eight components on the lower left corner of the lower module are damaged/missing. Only the eighth component has any labeling; it has eight pins and has the number 150 written on top.

I imagine that these components are fairly standard across DDR3 SDRAM modules and appear to be used all over the module. Is there any way to identify them visually or is there a reference schematic available somewhere that I could look at? or will I have to remove working components and measure their values by hand?

RAM: Toshiba Satellite P70 AST2GX1

Wed, 08 May 2019 09:49:03 -0700

RAM memory increase. This Toshiba Satellite model has 4 memory slots for a maximum of 32 Gb (DDR3L 1600MHz = 4GBx4 204 Pins). Currently they are occupied by 4 cards of 4Gb each (16 Mb in total). I want to do an upgrade but as I only have access to 2 of the 4 slots, I want to know: 1) It is possible to put 2 cards of 16 Gb (DDR3L 1600 MT/s) in the 2 accessible slots and leave the 2 non-accessible slots with their modules of 4 Mbs; 2) if it is possible how much RAM memory the system will recognize me (WIN 10) because it could reads only the 2 new cards (32Mb) but also reads 20 Mbs or 24Mbs.

RAM: Is this RAM Apple OEM? Black PCB

Mon, 05 Oct 2020 16:57:51 -0700

I purchased this RAM used for diagnostic purposes since I do not have any established DDR3L (and I can put this to good use so I'm not wasting it once I'm done with what I need it for) but I'm not sure if this is Apple OEM or retail modules that just happen to be black. I suspect it's Apple RAM based on the PCB, but I also know black RAM is available open market now.

Is this look like OEM Apple (no warranty) or retail Micron with a warranty?

RAM: RAM Upgrade Elitebook 8460P - PC3-10600s or PC3-12800s?

Sun, 06 Oct 2024 11:32:10 -0700

I have an Elitebook 8460p with Intel Core i5-2540m. It currently has 2x 4GB PC3-10600s. I wonder if I would face a problem if I upgrade it to 2x8GB Samsung PC3-12800s. According to the specs sheet,

Standard:

DDR3 PC3-10600 SDRAM (1333 MHz)

Two SODIMM slots supporting dual-channel memory

2GB, 4GB, and 8GB SODIMMs

Maximum:

Ungradable to 16GB with 8GB SODIMMs in slots 1 and 2

Dual-channel:

Maximized dual-channel performance requires SODIMMs of the same size and speed in both memory slots.

I am also planning to upgrade the CPU to Intel Core i7-2860qm which supports PC3-12800s in the future, so that's why I am considering PC3-12800s as an option. Please help.

RAM: Resoldered a resistor to DDR5 RAM, 0.29Ohm Vs 0.24Ohm, will I be okay?

Sat, 28 Jan 2023 12:52:33 -0700

Hello,

I recently re-soldered a resistor from a DDR3 stick to DDR5 as when I was removing the heatsinks one came off.

I took one from random DDR3 RAM and I tested with multi meter that the original one is 0.29 Ohm and the one I replaced is 0.24Ohm. (when testing with multimeter at 20K OHMs)

The sticks work fine when I put them in a PC. They're 8000Mhz ones, of course I don't have a CPU yet that can test whether they'll run at those speeds, but in BIOS XMP shows up fine.

Trace from the resistor leads directly into the RGB light diode on the RAM.

Please see included screenshot.

Will it affect the ram at all or I shouldn't be concerned?

Its the top empty space for resistor that was missing. FYI.

RAM: Why won't my laptop boot up?

Sun, 02 Jan 2022 17:14:17 -0700

I have an Acer Aspire 5742 laptop and I’ve just added an extra 4GB of RAM to give me a mighty 8GB in total! I have re-seated the RAM chips a couple of times now and I’m pretty confident I have seated them both correctly. When I press the Power On button, the screen shows the initial acer ‘splash’ screen with the instruction, “Press <2> to enter Setup.” There is brief sound of the hard drive coming to life then the machine powers down. It then restarts in a continual loop of this activity until I remove the battery and mains power supply.

I have pressed and get 4 (four) quick, short beeps before the machine powers down.

Any suggestions as to what I am doing wrong or need to do next please.
