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.)

I'v adde 1 gig/1stick of memory to my machine an it's fine. when I add the second 1 gig stick my machine will not even boot to bios? Any i advice on getting the second DIMM2 slot working. It also has a red...


Hello.

At this point, from what you described, the memory stick or the slot could be the problem.

First check the 2 memory sticks to be certain that they are compatible with each other - the type and speed. That could be your problem.

If OK, remove both memory sticks and try the second stick of memory in the first slot. If it works, the 2nd memory slot is problematic.

If it doesn't work, your 2nd stick of memory is bad and needs to be replaced.

If the memory slot is bad, there really is not much you can do except replace your motherboard.

Hope this helps.

ECS GF 8200A does not support more than 3 gig ddr2 memory


Is the mainboard capable of supporting more than 3 GB?

If it is then maybe you have the wrong kind of memory, or the slot is bad.

Take all your memory out and just try with the new stick in one of the good slots. If it works then we know the memory is OK so then try it in the "bad" slot.

Wont boot 2 windows xp home when 2 gig memory installed,works with 1 gig,tried both slots with both 1 gig sticks.Screen goes black.


Seems the memory is not comatable with the motherboard. Replace the old memory and visit http://www.crucial.com, they have a scanner tool which will confirm what mem can be installed.

Toshiba sattelite


The problem must be the amount of total memory. Maybe the board supports only 1 gig. Chek the manual.

Toshiba l45-7423 laptop has two memory slots. With 512 in each, runs ok. With 2 gig in top slot, 512 in bottom slot, runs ok. with 2 gig in bottom slot, says it has memory errors. this limits me to 2.5 gig...


HI embreelynn,

just want to check, did you left the top slot open when you put the 2gig in the bottom slot, if you do, I suggest you try it with the 512 in the top slot and the 2gig in the bottom, the reason is that some mobo implements "banking" which means that you'll have to fill in the 1 mem slot before the using 2nd, 3rd and so on.

hope this helps, regards.
