How many memory slots are on the motherboard?

Perhaps there is a problem with the 2nd slot in your motherboard.
Tr this - place the two memory sticks in the Outside two slots - the orange ones.
OR you didn't get the correct speed memory - usually the motherboard will interleave two slots to access the memory faster - than if only one memory module is installed.
The "DDR1" slot is the one closest to the CPU processor chip.
The manual for your mb can be found at: http://download.gigabyte.us/FileList/Manual/motherboard_manual_k8u939_e.pdf

Hi.

C1 is a memory presence error.

It can be a bad piece of memory. Remove all pieces of memory except one. Test each piece of memory individually.

It can be a bad memory slot on the motherboard. Take a known good piece of memory and move it between each slot on the motherboard to see which slot might be the issue.

Good luck and kind regards.

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.)

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.)

A) FixYa T.O.S. (Terms of Service) states to NOT post your email address.
The TOS is read when you join.

B) How about posting the MOTHERBOARD manufacturer name, and Model Number?

Also post what ram memory ,manufacturer, and manufacturer code on the ram memory module.

Ram Memory HAS to be in Slot 1. (May state DIMM 1 next to the ram memory slot. Can also be Slot 0, or DIMM 0 )

Slot 1 is the ram memory slot nearest the Processor.
A Processor reads ram memory Slot 1 first.

Do you know;

1) What is the Maximum TOTAL Amount of ram memory, for the motherboard?

2) What is the Maximum Amount for EACH ram memory slot?

3) What type of ram memory is supported?

For an example;
Can it use DDR Sdram at either 333MegaHertz, or 400MHz?
(PC2700 and PC3200, respectively)

4) What ram memory slots have you put ram memory in?

Post back in a Comment.

hello,
try booting up one memory at the time
-memory 1 to memory slot 1 boot computer see if it will work. -memory 1 to memory slot 2 boot computer see if it will work.
-memory 2 to memory slot 1 boot computer see if it will work. -memory 2 to memory slot 2 boot computer see if it will work.
the reason for doing this is to make sure w/c one is defective if it is the memory slot or the memory it self, you can also check the manual to see what the maximum memory the motherboard can have.
cheers

You have 4 slots available. Each slot can take a 1gb non ecc memory module with the specs below.

4 DDR II DIMM memory slots (supports up to 4GB memory) 
Supports 1.8V DDR II DIMM 
Supports dual channel DDR II 667/533/400 DIMM

Not required to put the same memory. Any card will do as long as it fits right :)

Are you sure the stick of RAM you are using isnt made by Rambus? If it is it will have to be paired with another stick of the same type. Also try using the other slot.
