I have 4 RAM slots, 2 are red, 2 are yellow. Will it halve the speed of my ram (2 sticks) if i put one in red and one in yellow (as opposed to both in the same colour)? As the other 2 slots are obstructed? RAM slot, socket, or a memory slot is a gap on your computer’s motherboard where you can insert your RAM. Depending on the motherboard type, there might be up to four memory sockets. If you have a high-tier motherboard, you can even have more.

1. Adding more memory, or RAM, is the best thing you can do for your PC. More memory provides an instant boost to the system. Adding memory to your computer is simple. However, adding memory isn’t something to be taken lightly. Unless you’re comfortable upgrading your PC, consider having a computer expert or repairman do the.
2. Most modern computer system use Multi-channel memory architecture. This means that memory installed in different memory sockets can be accessed simultaneously, potentially doubling, tripling, or even quadrupling the speed at which data can be tran.
3. The unit needs to have the RAM modules on the primary slots of each memory bank, this means that you have to use the 1st and 2nd slots (one black and one white), number 4 and 5 of the diagram on page 19 of the manual. 0 Kudos Tesla1856 7 Thorium.

For those of you who prefer to build their own PCs, sometimes you begin to wonder what you can do with the slots and ports you don’t always take advantage of. For example, we commonly run across questions involving the PCIe 1x slot on a motherboard and what it can be used for. Those longer 8x and 16x slots are mostly dedicated to your video card (or cards), but not everyone knows what they can accomplish with that shorter 1x slot. So I will run you through some of the more popular uses of that slot so that you can make the most of it.

I’ll start off with a bonus tip by pointing out that 1x cards can be used in any PCIe slot, including those 8x and 16x slots. So if all you have left is one of the longer slots, all of the below can still be accomplished using one of those slots as well. You would simply take up the portion of the slot in relation to the smaller slot. You can see this in the following video where Youtuber R3DLIN3S demonstrates how 1x and 4x card achieve this–so you can get an idea of what I am talking about.

For now though, we are going to focus on those smaller slots and some of the many ways you to make use of them while enhancing your rig with new upgrades.

Port Expansion Cards

One of the most common uses of the 1x slots is for port expansion cards where users are looking to increase the number of specific ports on their PC. Generally, this will include USB (all versions), SATA for expanding on the number of internal drives you have doing and Firewire for those still looking to make use of that connection for specialty storage devices and video tools (ie, cameras).

For example, let’s say you built your PC a few years back and the fastest USB you have is 3.0. Now you are beginning to see all of these devices pop up that take advantage of the new USB 3.1 and you want to be able to start taking advantage of these. Faster data transfer rates, quicker charging and so forth. Chances are, your motherboard won’t have a USB 3.1 header (pins) connection to directly add ports with (only the newer most recent boards are beginning to sport them). Instead, you would find a PCIe 1x card that works best for your function and budget and slap it in there. Now you have USB 3.1 and can start drooling over those new speeds.

If your board only comes with 4 SATA ports and you have 3 hard drives and two optical drives (ie, DVD burner and a Blu-ray player), you can find a PCIe 1x card to expand on those SATA ports with so you can add that extra hard drive as well as a few other things maybe (depending on the card you buy). Some of these cards also include an eSATA port on the outside for external SATA devices.

NVMe (M.2) Drive Slots

NVMe is the future for hard drives when it comes to transfer speeds, providing some of the largest leaps in file transfer rates that we have ever seen in the history of storage evolution. A (modern) normal spinning HDD (hard drive) will typically transfer at around 120-180MB/s, where NVMe can travel at up to 3,200MB/s and growing. So it is no surprise that they have become the next biggest commodity for computers, offering incredible boosts for system boot-up and file access speeds. The only catch is that they require an M.2 slot on your motherboard. If you don’t have one of these, you’ll have to find a PCIe expansion card that can adapt using one of your available PCIe slots.

They are available in PCIe 1x options, providing one or two M.2 slots. Slap one of those cards into your computer and begin enjoying the benefits of NVMe.

Sound Card

It isn’t too common anymore where you would need to expand on the sound card that is integrated into your motherboard since most of the boards today and nearly anything in the recent past include everything you need up to 7.1 digital connectivity using analog connection and/or optical SPDIF.

However, some enthusiasts prefer to have a separate source either because it might prove to be cleaner than their integrated chipset, offer strong amplification or simply sound better in general due to enhanced surround features or even a built-in DAC. Say you have a normal Realtek integrated chipset on your board and it sounds really great. However, you notice that you can only get surround when you have a surround source. It may not be able to take a stereo signal and process it into an enhanced surround delivery. In this case, you would want a dedicated sound card to pull this off with and you would look for something from a company like Soundblaster. It doesn’t have to be PCIe as you can also go USB 3.0 to an external unit somewhere, but what if you want it as a card built-in and want to fill one of those 1x slots? So you could search for the PCIe 1x sound card that fits you best and jump on enhancing your sound.

Some people, however, tend to flock towards external docks to keep the connections closer or separate from the back of the PC since it could also include things like MIDI connections and volume controls and so much more. This may lead you back to something like USB 3.0 or equivalent but some of the PCIe cards also include the option of tethering an external dock to the back of the card as well.

These dedicated cards usually feature all sorts of things such as the various formats of Dolby and DTS sound, DSP features, multiple input and output opportunities (both analog and digital), stronger processing using faster more reliable (and cleaner) chipsets and so forth.

Modems, Network Cards (wired and wireless)

Another common use for that 1x slot is to expand on your network or phone capabilities by adding these ports through this method. If your motherboard doesn’t have an RJ11 jack with a built-in modem (which most of today’s motherboards won’t) and you need one badly, you can do so with PCIe. Given, most people couldn’t care less about a phone jack on their PC anymore–however, some may still be looking to use their PC as a fax machine since people still use this method for communication for some reason.

So let’s take a look at your motherboard’s ethernet. What if it doesn’t have ethernet integrated into the back of the board? Today, this is quite unlikely, but maybe the integrated ethernet adapter it shotty and doesn’t perform to your expectations. Maybe you prefer to have an ethernet card by Bigfoot Networks or simply anything but the one built into your board. Or, you want to add WiFi to your system because running a physical cable to it just isn’t convenient for you. Then you could look for a PCIe network or WiFi card for your system and add it via one of those slots. A lot of the ethernet cards are quite affordable running less than $40, while a lot of the WiFi cards can run similar to a little more if you are looking for killer performance. For the higher performance options, you may expect to spend anywhere between $50-$150 depending on how serious you are.

TV Tuner

You can always throw a TV Tuner card in there so you can watch live TV on your PC. Especially good if you have a multi-monitor setup or want to use your PC as a feature rich DVR. This is definitely a specialized want vs a need in most cases, but sometimes this is a valuable option for users.

Video Capture

Let’s take that TV Tuner option one more level with a complete video capture card! Expand past just TV and consider any video source such as a camera or other external device like the DVD player connected to your TV. Maybe you want to convert all of your old family VHS tapes (remember those?) to digital files? With a video capture card, you can pull all of this off with. Certain cards come with different features, with almost all of them offering your basic analog RCA connections in one form or another.

With the newer models, you now have HDMI as well. In some cases, you can even buy adapters to adapt HDMI to just about anything you want. Typically, either you can find a card or an adapter to accomplish what you need to capture, let it be digital or analog, RCA, HDMI, SDI, DisplayPort, SVGA and so forth.

Video Card

Of course, you could always opt to use a video card in one of those smaller slots. However, you can expect very little performance compared to an 8x or 16x slot–32x is also starting to make its debut into the world. Some motherboards may only offer the 1x flavor of PCIe, in which case it may be your best bet. PCIe 1x is faster than regular PCI but it won’t compare to anything 8x and higher. Unless it is just a test system running in the corner for basic input needs, you would be better off upgrading to a new board or tower vs using 1x for your main video output card.

Which Ram Slot To Use

So there you have it! Some of the many uses of a PCIe 1x slot on your motherboard. You may find yourself jumping at the opportunity to fill them up or simply ignoring them and moving on. It depends on the level of user you are. Most people find themselves leaning on them for expanded ports as mentioned. Different needs for different people.

How about you? What do you use (or foresee yourself using) those PCIe slots for? Feel free to share your own setups or plans below. We would love to hear from you. Happy building!

I have been asked many times by my blog readers that whether they should use a single large stick of RAM or multiple RAM sticks (mostly two) to run in dual channel mode. So I have decided to write a post on this issue and clear the doubts of my blog readers on which RAM configuration they should choose and which one is best for them.

What is Dual Channel Memory Mode?

In dual channel memory mode the bandwidth between the RAM and Memory controller is doubled. In dual channel mode the memory controller on the motherboard utilizes two different 64-bit channels for communication with RAM. This leads to total bandwidth of 128 bits to move data from RAM to the CPU. This eliminates the problem of bottleneck where a higher FSB (Front Side Bus) CPU is left with nothing to do so as the single channel memory is busy with reading or writing the data.

So when the memory is operating in dual channel model then one channel is used to handle the reading and writing of data and other channel is used for loading, refreshing, and housekeeping functions. Here we can say that there is a simultaneous two way parallel communication between the memory controller and RAM. This leads to increase in overall performance of the system.

It must be noted that dual channel architecture is a motherboard feature or technology and is independent of RAM types. You can run any two identical types of RAM in dual channel mode. All Memory types i.e. DDR, DDR2, DDR3 RAM supports dual channel memory mode.

To run memory in dual channel mode the two RAM should of same capacity, make and speed (not necessary but preferred to avoid issues). Dual Channel works in pairs i.e. 2, 4, 6 etc.

A motherboard supporting dual channel memory configuration has its memory slots color coded to indicate that you should put memory of same type in the slots with same color to run or use them in dual channel mode.

Color Coded Memory Slots indicating Channels

Some modern day Processors like i7 can support triple channel and quad channel memory configuration. Also Modern CPUs like Intel i3, i5 & i7 has memory controller integrated in them which leads to faster access of data and it also helps in reducing memory latency.

Requirements for Dual Channel Memory Mode Configuration

• Dual Channel enabled Motherboard
• Two Identical RAM Sticks of same size

Performance Gain by using Dual Channel Memory Mode

Theoretically dual channel architecture doubles the throughput and bandwidth, but in real world the performance gain is not too much. The amount of performance gain when using dual channel memory mode is around 10% – 15% only (also depends on various factors, PC & Memory specs).

Which Channel Configuration to go for?

Here I tell you which memory configuration is best for you, whether it is single channel or dual channel?

For Normal Work – If you are building a PC for normal day to day office work, watching movies, casual gaming, internet surfing & browsing then you should go for single channel memory configuration only.

For Gaming & Performance PCs – For Gaming and high end PCs I would suggest you to go for Dual channel or Quad channel memory configuration to get maximum performance.

For Future RAM Upgrade – If your motherboard has got only two RAM slots then I would advise you to get a single large stick of RAM in single channel configuration only. This is because it will be easier and cost effective for you to upgrade RAM in near future.
