My mobo has 4 memory card slots


1) All of your memory must be compatible with your motherboard (DDR, DDR2, or DDR3 and speed and latency). For best results, if you have dual channel capability, each pair of memory sticks should be matched. (Usually consecutive serial numbers indicate pairs from a given manufacturer.) Both sets of memory should be rated at the same speed (or the slowest speed will be your memory speed). Some motherboards may not work with all 4 slots occupied unless the memory was certified to work as a set of 4.

2) Which motherboard do you have? The motherboard manufacturer and memory companies often will have lists of compatible memory. The motherboard manufacturer will also have information on the dual-channel pairing.

My current and previous motherboards have had memory slots in color pairs (blue, black). For my boards, I put the sticks in the blue slots (A2 and B2) first. (Preferably these should be the largest memory capacity.) Then I put the second pair of memory into the black slots (A1 and B1). DIMM slot A1 is closest to the CPU; B2 is the farthest away from the CPU.

Depending on your CPU cooler, you may need to remove it or modify it to use all 4 DIMM slots.

Observe the appropriate steps to avoid static discharges while handling your memory and when inside your computer. For actually inserting the memory, make sure that the locks (white on my motherboards) are fully open (hinged away from the slot). Line up your memory so that the slot in the memory is on top of the key in the slot and the memory is centered in the slot. It will only line up one way; the wrong memory type will not line up. Push your memory stick down fully until the locking clips rotate up and fully engage the memory. (You may need to push down at multiple places to get it fully seated.) You will then repeat the procedure with the rest of the memory.

Note: if you get a memory error, three beeps (on many boards), you will need to remove the memory and test one stick at a time in the A2 slot (for example). Then test pairs of slots. It is not unknown for either one stick to be bad or one slot to be bad. Look at the total memory your OS identifies, if you manage to boot in spite of any issues. Running Memtest may be needed but even that may not identify which specific memory segment is bad.

I hope this helps.

(who has installed or replaced memory since giving an 286 computer a full megabyte of memory. DIMMs are a lot harder to mess up as long as you have the correct memory. Note: most of the different DIMM types have different number of pins; thus sometimes it's very easy to tell that the wrong memory is being used. This isn't always the case.)

What's your problem?bit ix38 quad gt motherboard with 2 gig of ddr2 ram i want to add a 1 gig stick of more ram that ive bought how do i do this? thanks windows seven


Top view of motherboard, scroll down. (Thought you might also like to read the reviews, and Comments)

http://www.bit-tech.net/hardware/motherboards/2007/12/06/abit_ix38_quadgt/2

Motherboard User Manual,

http://www.theraptorpit.com/forum/index.php?/forum/124-abit-motherboard-tech-support-unofficial/

1) On the motherboard the Blue ram memory slot that is closest to the copper heatsink, is ram memory Slot 1.
Also known as DIMM 1.

Ram memory ALWAYS has to be in this ram memory slot.
The Processor reads ram memory Slot 1 first.

2) The Blue ram memory slots are Slot 1 (DIMM 1), and Slot 3.
(DIMM 3)
The Black ram memory slots are Slot 2 (DIMM 2), and Slot 4.
(DIMM 4)

To run Dual Channel ram memory, means there are two LIKE ram memory modules ('Stick'), and they are installed in the SAME channel.

This would mean to alike ram memory modules, in both Blue ram memory slots, or both Black ram memory slots.

Since the ram memory modules need to be alike, they are generally purchased from the same manufacturer, and are the same kind.

Running ram memory in a dual channel configuration, is supposed to increase ram memory 'speed', up to 30 percent.

This is Baloney!
May look good on paper, but in actual use in the field it's cr@p.
Actual performance increase is more like 1 to 2 percent.
This has been proven by Tom's Hardware, and many, many motherboards, ram memory, Processors, etc.

So you have 2GB of DDR2 Sdram, huh?
Is it just one 'stick' of ram memory, or are you referring to two 1GB sticks?

If the above holds true install them in Slot 1 and Slot 3.

If not, and it is a 2GB stick of ram memory, be sure it is installed in Slot 1 (DIMM 1)
Install the 1GB stick in Slot 2.

It isn't the same as the 2GB stick.
It is 1GB.
Does NOT go in a dual channel configuration.

(Catching all this? There is NO dual channel ram memory!

It is ram memory that is -> ALIKE, and used in a -> dual channel configuration.
Used in two separate ram memory slots, that support the dual channel configuration.

Sold with the advertising scheme of 'Dual Channel', but really just means the two ram memory modules, (Or four), are -> alike.

1) Same Voltage used
2) Same Ram Timings
3) Same Chip Configuration
4) Same size in amount
5) Same frequency rate ('Speed')

With ram memory in a dual channel configuration, the ram memory modules team up on the task.)

Scroll down to the larger photos of the motherboard.

Notice how the one Black ram memory slot is closer to the Processor?
That is Slot 1.

Keep the ram memory in the same color of ram memory slots.

Note*
IF you have the SAME ram memory modules ('Stick') in the Black slots, you will be running the ram memory in a dual channel configuration.

Same thing for the white ram memory slots.

Most generally the ram memory 'sticks' are bought from the same manufacturer, so as to guarantee they are indeed the same.

Same 'speed' (Frequency rate, actually)
Same voltage used
Same ram timings
Same chip configuration

Having the two LIKE ram memory modules installed in a dual channel configuration, allows them to team up on the task at hand.

Purported to speed up the ram memory functions greatly.
Up to 30 percent.

This has found out to be bullsticks.
The actual increase is more like 1 to 2 percent.
Nothing to write home to Mom about.

(Tom's Hardware used MANY different motherboards, ram memory, processors, and associated hardware, and tested different ram memory.
All came to the same conclusion. 1 to 2 percent increase.
Why do gamers use dual channel configuration?
1 to 2 percent increase. EVERY little bit helps)

I using a dual channel configuration for your motherboard, two LIKE ram memory modules are installed in Slots 1 and 3, (Black)

Have four LIKE ram memory modules? They go in Slots 2 and 4.
(White)

Can you put 2 igb memery into the blue connectors and 2 512 gb into the black connectors


Yes, provided;

A) The Maximum Total Amount for the Ram Memory is at least 3GB.

B) The Maximum Amount for each Ram Memory slot is at least 1GB.

C) The first blue connector is ram memory Slot 1. (DIMM 1)

The Processor 'sees' the Ram Memory in Slot 1 first.
If there is a large amount of ram memory, (1GB), and a small amount (512MB), the large amount goes in Slot 1.

ALL ram memory must be the same 'speed', (Frequency Rate), or the slower ram memory 'speed' will be used.
If there is too much of a difference it may not work at all.

Ram memory needs to be 400MHz, or 533MHz, for your computer.
{DDR2 Sdram at 400MHz = PC2-3200
DDR2 Sdram at 533MHz = PC2-4200 (Also known as PC2-4300)

I'm doing a memory upgrade. i have four memory slots, 2 blue and 2 black. i have two, 2g dimms; for dual channel operation do i use the 2 blue slots or the first blue slot and the first black...


Try them in the same-colored slots, nearest the processor. It seems ASUS (who makes your mobo) has chosen to color code their slots so those of the same color enable dual-channel. If you can't tell from the BIOS detection, try CPU-Z to verify that the memory is in the correct slots for dual-channel operation. Putting one in the wrong slot should not damage anything. It would just make it so you can't take advantage of the extra speed.

Hi,
Okay, you don't need two video cards. Your 4 memory slots are grouped in two's. One set is black and blue, and the other set is black and blue also. These are your dual memory channels.

The reason you can't see more than 2 gig ram is because you are probably not running 64 bit Windows with a 64 bit processor.

32 bit windows will only display 2 gigs, but max memory is 4 gigs. It will draw on the extra 2 gigs if ever it is needed, but this does not happen very often, if ever.

Memory banks 1 & 2 are where your computer looks for RAM. If nothing is installed in them then the computer looks no further. You can upgrade RAM by putting 2 more sticks in the unused banks as long as they are compatible to the board and first 2 sticks. It makes no sense to buy faster than the first 2 as the cpu would make them run at the lowest speed of all installed RAM. If you are using an asus board then when you boot up you should be able to press the del key to enter bios setup. Video cards are more to preference. If you have the psu & board capabilities then the sky is the limit. Hope this helps & please remember to rate my answer. Thanks.
