Memory Slot Function

Yes you are going to have reduced performance due to the way Dual channel works. For dual channel to work correctly you need have your ram configured one of these 3 ways: slots 1+3, slots 2+4, or slots 1+2+3+4. Some RAM manufacturers make dummy modules to fill in the empty slots to make for a uniform RGB block I don't know if Gskill does or not. You mention SD (Secure Digital) cards, so you must mean the SD slot in some laptops. There are two main purposes in putting an SD slot in a computer. One is so that you can take an SD card out of a camera and read it to down load the images withou.

Is it possible to fix laptop memory slot failure with a guitar pick? Yes, it is. You will not fix the memory slot itself, but you can work around the problem. 🙂
Today I received a Toshiba Satellite Pro 4600 laptop with the following complaint:

The laptop starts and works properly, but recognizes only one of the two memory modules installed. The laptop has two 256MB RAM modules installed, but registers only 256MB.

First of all, I removed the memory cover to find out if both memory modules are installed correctly. The laptop had two 256MB Kingston modules installed and they were seated properly.

When I started the laptop and entered the BIOS setup menu, I found that only one of the two memory modules is detected and the laptop registers only 256MB (262144KB) of RAM instead of 512MB (524288KB).
Just a side note. In the computer world 1MB=1024KB. That’s why 256MB=262144KB and 512MB=524288KB.

I tried reseating both memory modules but it didn’t help.
After that I tried installing both memory modules in both memory slots one by one and here’s what I found. The laptop worked absolutely fine when both memory modules were installed into the slot A, but failed to boot with both memory modules installed into the slot B.
Apparently, there is nothing wrong with the memory modules and the laptop has a faulty memory slot B. The memory slot is permanently soldered on the motherboard. If one of the slots fails you’ll have to replace the whole motherboard or use the laptop with only one working slot.
Buying a new motherboard for this older laptop wouldn’t make any sense because it’s too expensive, but the laptop is still in a good working condition except the faulty memory slot B, so I continued playing with that trying to find the solution.

I noticed that the laptop start normally with the memory module installed into the faulty slot if I slightly press on the module with my thumb. And this gave me an idea.

This guitar pick is going to fix my laptop. 🙂

I installed both RAM modules back into the slots and then placed the guitar pick over the module in the slot B as it shown on the picture.

I thought if I close the RAM door it will press on the guitar pick/memory module and it will have the same effect as pressing on the module with my thumb. And it worked!

Both memory modules were detected properly and the laptop registered all 512MB. After “the fix” I tested memory with Memtest86+ and the laptop passed the test.
I wouldn’t call it the best solution for fixing a faulty memory slot but in some cases it will work.

By the way, I didn’t charge the customer for this “repair”, he knows what is going on and how I “fixed” his problem.

Choose the role played by the card in the secondary slot when two memory cards are inserted in the camera.

If [On] is selected for [Multiple exposure] > [Save individual images (NEF)] in the photo shooting menu, or if [On] is selected for [HDR (high dynamic range)] > [Save individual images (NEF)] in the photo shooting menu, unprocessed copies of the individual NEF (RAW) photos that make up each multiple exposure or HDR image will be recorded to both memory cards together with the JPEG composite, regardless of the option selected for image quality.

The shutter release is disabled when either card is full.

• Use the [Dual-format recording PB slot] item in the playback menu to choose the slot from which dual-format photos are played back.

• When viewing dual-format photos, you can view the other copy using [Jump to copy on other card] in the i menu.
