Can't Install RAM in DDR2 and DDR3 DIMM slots

I am not able to add more ram because the machine does not boot when I add memory in the second and third slot. I have tried five memory sticks all pc2100 DDR 184 pin RAM in size 1 GB, 512 MB and 256 MB and all work in the first slot. However when I start adding modules in the second or third slot the machine does not start.

Is any BIOS setting Ithat can effect this. Actually I have 1 GB in DDR1 slot and the machine runs fine.

Re: Can't Install RAM in DDR2 and DDR3 DIMM slots

You cannot use DDR and DDR2 ram at the same time, because its always been like that (ie, no SD and DDR, or SD and RIMM)

What you should do is switch to all DDR2 sticks.

Hello here is the homepage:

I think you have a ram problem:

1. Please install the memory module into the white slot (DDR3_A1,
DDR3_B1 or DDR3_C1) for the first priority.
2. Due to Intel CPU spec definition, the system will not boot if only
one DIMM is installed into DDR3_A2, DDR3_B2 or DDR3_C2 slot.
3. Due to Intel CPU spec definition, XMP DIMMs and DDR3 2000/
1866/1600 are supported for one DIMM per channel only.
4. You may install varying memory sizes in Channel A, Channel B and
Channel C. The system maps the total size of the lower-sized
channel for the dual-channel or triple-channel configuration. Any
excess memory from the higher-sized channel is then mapped for
single-channel operation.
5. It is not allowed to install a DDR or DDR2 memory module into
DDR3 slot; otherwise, this motherboard and DIMM may be


Try only with one module, in the white slot.

Hope this will help you.

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)

Motherboard User Manual,

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.)

Ihow to boot up and get display and set bios on msi motherboard g41m-e43

Add one item at a time.
First memory, then graphics card.

Plus you cleared CMOS Error Codes, and set the BIOS Setup parameters back to the factory default settings.

Guess what the default graphics setting is for an MSI G41ME43 motherboard?

Yep, AGP.

[Wow, I like MFlash, and the solid Polymer capacitors.
Live BIOS Update 5, and Easy OC Switch.

However if the motherboard fails, I'll bet the Integrated Circuit, (I.C., or 'chipset'), that controls APS, is the first electronic component to go.

I would also watch OC'ing. Has to be done in incremental steps. Automatic feature or not. A 20 percent boost is A LOT.
Hardware components have as tendency to heat up.
Watch it as this lowers the 'life expectancy' of the chips.
Heat - 'Kills' ]

Motherboard chipset:
Northbridge is an Intel 82G43. Southbridge chip is an Intel 82801GB part number. (ICH7) You can't see them as they are under Heatsinks.

Scroll down.

Ram Memory:
Two ram memory slots for Dual Inline Memory Modules on the motherboard. (DIMM)

B) 1.5 Volt (DC)
C) DDR3 Sdram at either 800MegaHertz, or 1066MHz.

[ This puzzled me. DDR3 Sdram at 800MegaHertz?
Why would anyone want to use DDR3 Sdram at 800MegaHertz?
Seems to me going backwards.

Faster frequency rates.
Low end for DDR3? 1066MHz.
High end for DDR2? 800MHz.

DDR3 is faster in comparison to DDR2 per se, because of the prefetch buffer. 8 burst deep compared to DDR2's 4 burst deep.
(Or DDR's 2 burst deep)

Not because of the CAS Latency, though.
DDR3 has a much higher CL, than compared to DDR2.

(Average CL for DDR3 at 1066MHz = 7-7-7-20
DDR2 = 5-5-5-15. Note* -> A-V-E-R-A-G-E. )

When using DDR3 Sdram at least use 1066MHz, IMHO
The maximum ram memory frequency rate, that your motherboard will support ]

So what manufacturer of ram memory is it, and what is the manufacturer code of the ram memory module/s? ('Stick')

JEDEC sets the standards for Ram Memory.
Voltage standard for DDR3 Sdram ram memory is 1.5 Volts (DC)
So the factory default setting is 1.5 Volts, for the motherboard.

However your motherboard supports SPD.
(Serial Presence Detect, )

Point of the above?
If you are trying to use high-performance ram memory; say one needing a slightly higher voltage, and/or has lower CL ratings; then the SPD on the motherboard may make automatic adjustments.
(Adjustments to the parameters in your BIOS Setup)

May take 2 to 3 'Cold Boots', though.
(Turn the computer all the way off. Wait 1 minute. Turn the computer back on = Cold Boot)

I order for SPD to work, BOTH the motherboard, AND the ram memory, have to have SPD feature.
If the ram memory is too low in quality, (Read cheap), it may not have SPD.

Means you have to go into BIOS Setup, and set the ram memory parameters, manually.

[ Delete key to enter BIOS Setup.
Main BIOS Setup menu > Cell Menu > Memory Z > Advance DRAM configuration >
1) DRAM Timing Mode
2) CAS Latency
3) tRCD
4) tRP
5) tRAS
6) tRTP

Don't forget you have to SAVE changes, or it will be as if you have done nothing at all.

If a mistake is made;
Go back to BIOS Setup, and in the Main menu, use the Down Arrow key to arrive at Load Fail-Safe Defaults. IF -> OK is 'highlighted' (Black surround) press the Enter key. If not, use the Right Arrow key, or Left Arrow key, and highlight OK ]

The ram memory also has to be UNBUFFERED.

Unbuffered ram memory is the opposite of Registered ram memory.
Registered ram memory is more stable, usually one clock slower, and more expensive, than compared to unbuffered ram memory.

Registered ram memory is usually used in SERVER computers.

(A Server computer may look at information 2 or 3 times, before it acts on it. It needs to be C-O-R-R-E-C-T for a server computer )

"Cleared the board i believe"

Turned the computer off? Unplugged from power? Pressed the Power ON button in, and held it in for a count of 10 seconds? Then let go of the Power On button, then performed the entire procedure again, 2 more times?

{Clears CMOS Error Codes, and resets BIOS Setup back to the factory default settings}

You MAY have cleared the motherboard. It's what I use, and have recommended for years on the 'net. Doesn't mean it always works, though. Sometimes you just have to go into BIOS Setup, and set the parameters back to the factory default settings.

(For you? Load Fail-Safe Defaults )

A) Won't boot:
Because the ram memory is the wrong one, (Or ones); OR, the ram memory is high performance, and BIOS and SPD hasn't recognized it yet.

Remove the graphics card.(Computer unplugged from power. Anti-Static Precautions FOLLOWED!)
Remove the ram memory.

Reinstall the old ram memory, and plug the monitor into the VGA port, in the I/O area on the back of the computer tower.

Just get the computer working again. After about 10 minutes of fooling around on the computer, ('net?), turn the computer off.
Install the new 2GB.

(IF, just one ram memory module, be SURE to put it in Slot 1.
{DIMM 1} The ram memory slot closest to the Processor )

Leave the computer case open. You may be going back in pretty soon. (Graphics card)
WAIT 1 minute, then turn the computer on.

If no joy shut the computer down. (Press the Power On button in, and hold it in for a count of 10 seconds)

WAIT 1 minute, turn the computer on.
If it doesn't work this time, you may wish to try it again.
Sometimes takes 2 to 3 times, before the high-performance ram memory is recognized.

You can also go into BIOS Setup, as mentioned, and physically set the ram parameters.
After 3 times I would give up however, and send the ram memory back. Wrong one/s.

If you get the new Ram Memory working, Cool!
If not remove it, and use the old ram memory.
Might as well get the computer going with the new graphics card, while you wait on the proper ram memory to arrive.

Did you plug the monitor into the graphics card?
Sometimes we computer geeks get in a wee bit of a hurry, when we get shiny new parts. Make sure the monitor cable is plugged into the graphics card.

There is another tiny thing; DRIVERS
If you did not use the Installation Disk (CD) first, THEN physically installed the graphics card, you are Wrong.

OR downloaded the drivers from EVGA.

What happens if you physically install a graphics card, THEN come back and install the drivers?
Most of the time a Driver Conflict.

Windows: "Which drivers do I use? These or THESE?"

Also sets BIOS Setup to the correct graphics aperture.

With the computer set back to the factory default settings, and the monitor plugged into the VGA port on the motherboard, you can get Windows running, and install, or download AND install, the Drivers.

ONCE the drivers, (And user interface -> Nvidia Control Panel), have been installed, you can then physically install the graphics card.

[Again; If you download the drivers, do NOT forget you have to go to where they are downloaded, and DOUBLE-click on the file, then use the Installation Wizard. (Or double-click on the .exe file)
INSTALL them! ]

Drivers installed, close all windows, go back to your desktop screen.
Turn the computer off. Unplug from power. FOLLOW Anti-Static Precautions. Physically install the graphics card. Plug the monitor into the graphics card. Plug the computer back into power. WAIT 1 minute, turn the computer on.

Asrock g31 m motherboard will only post if only one ram slot occupied , will not post if both slots are used , identical matched pair of ram ddr 667 800 mhz crucial ballistix both tested in another ri

I did some research. You didn't say what density the RAM was, but everything I can find on the Ballistix 800 MHZ DDR2 states that it runs at 2.2V. The standard for DDR2 RAM is 1.8V. You motherboard has both and AUTO and manual setting capability for memory (DRAM) voltage. It is possible that the AUTOP feature is not detecting the need for 2.2V, and that with only one DIMM installled, the memory marginally functions, but with the extra loading of the second it will not. Boot the system with the single DIMM, go to the BIOS, and set the DRAM voltage manually to the 2.01V setting (Verify by the part number of the RAM with the CRUCIAL website that is uses 2.2V before doing this). Once you have changed the voltage in BIOS, shut down and add the second DIMM and see if things improve.

Why cant i get my 4x 2gb ddr2 800 to work on my asus p5qc mobo? it will run fine with just 4gb 2x ddr2 800 but when i add the other 2x ram i get black screen at boot

Be sure to check which slots you are putting them in, stay within the same colors as to which needs to be put in.

This may be why, looks like your using DDR2
DDR2 1066MHz DIMMs work only on the black slots for one DIMM per channel. Ensure to install the DDR2 1066MHz DIMMs ONLY on the BLACK slots!

This may be the case for all speeds of DDR2

I have intel dg41rq motherboard with 2 gb kingston 667 mhz in one slot. can i put another 2 gb ram in other slot. if yes then should it have the same specification?

Intel DG41RQ Motherboard has two DDR2 (DIMM) sockets.
It Support DDR2 800 or DDR2 667 MHz DIMMs. Since you already have a 667 MHz RAM, it is recommended that you add another RAM of the same specification (DIMM DDR2 667 MHz)
However, if you add 800 MHz DIMM with 667 MHz, both would perform at 667 MHz. RAMs of different bus speed and latency usually work together but the performance is compromised.
It is always better to have RAM in pairs of same specification.

Hope it helps! Good Luck! Thanks for using Fixya!

I am using this ASUS (asus M2N-MX nvidia mcp61p chipset

According to the manufacturer's web-site:

this motherboard has 4 x DIMM sockets,
supporting a maximum of 4 GB
of DDR2 800/667/533/ Non-ECC, Un-buffered Memory

and supports Dual Channel memory architecture.

So, add one 512MB DDR2 533 Mhz RAM into one of the slots,
being sure to leave *ONE* *EMPTY* slot between the two sticks,
in order to enable the high-performance "dual-channel" option.

Try your computer -- it should feel faster.

If you still think that need more RAM, buy two 512MB (or two 1024MB) DDR2 533 Mhz RAM, putting the 2 sticks into the two empty slots.
