Re: What kind of ram should be used?

The easiest way is if it's still in use go to and let it search your board and tell you the type you require. If it's not in use if it's SDRAM then PC133 is the only speed you can readilly get hold of, or PC3200 if it's DDR as it will be backward compatable.

Is this a Mercury motherboard? And is that P 'eye' G3 'eye' T?
Or P L G3 L T?

What is the question?

Ya know Dual Channel memory is overrated, right?

If a motherboard is capable of using Ram Memory in a Dual Channel configuration, it has two Channels.
Motherboard with 4 Ram Memory slots has two slots in one channel, and the other two slots in another channel.

The two ram memory modules ('Stick'), MUST be alike.
Same frequency rate ('Speed')
Same type
Same ram timings
Same chip configuration
Same voltage

This is why it is best to use two ram memory modules that are alike, AND from the same ram memory manufacturer.

When ram memory is used in a dual channel configuration, the two ram memory modules team up on the task.
Kind of like Batman and Robin.

ON paper it looks good. many thought they were getting an increase of up to 30 percent, in ram memory performance.

In reality it is more like 1 to 2 percent.

Tomshardware performed MANY tests, using MANY motherboard/processor/ram memory configurations, and found this out.

So why do gamers use Dual Channel configuration?
Hey, 1 to 2 percent IS an increase, lol!
EVERY little bit helps.

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.)

N1996 motherboard 4 fast bios beeps

The beeps actually refer to memory not just RAM, it could be the memory on your graphics card or the cache ram on your processor. Or it could be a compatibility issue between memory sticks.

What kind of memory can I use in my 6282-75u

IBM 300GL 6282-75u

IBM = Manufacturer

PC300 = Series

PC300 GL = Subseries

6282 = Machine Type

75u = Model

Intel Pentium processor or Intel Pentium with MMX technology, and max frequency rate ('Speed') is 200Megahertz. (200MHz)

Two ram memory slots.
EACH slot can hold a maximum amount of ram memory -> 64MB

TOTAL ram memory amount for motherboard is 128MB (Woo-hoo!)

Ram memory is SDR Sdram. Commonly, but mistakenly, just referred to as Sdram.

Has 168 gold plated contact pins. 84 on each side.
Two Locating Notches on the bottom of the ram memory module.
(Two Side Notches. One on each side)

Non-ECC and 100MHz as shown above. (PC100) [ DIMM ]

I don't know if you can just use a 128MB ram memory module ('Stick'), in ram memory Slot 1, or not.
I would try it. May have to reboot up to 4 times for BIOS to recognize the ram memory. May NOT have to.

Under the bold white heading in the black bar -> Technical manual
,click on the blue -> [+] Click for files.

It is a PDF file, and the HMM for the IBM 300GL-6282-75u Desktop PC.
(Hardware Maintenance Manual)

Cheap buy on PC100 - 128MB - ram memory modules,


You have a D.I.P. switch on the motherboard. SW1
Has 4 dip switches, numbered 1 through 4.
The positioning, (ON or OFF), determines the 'speed' support for the Processor.

Why does memory upgrade for biostar k8m800-mam2 motherboard cause memory error beeps?

I would verify that the memory you're using is actually working properly.
Try to boot to the new stick and see if it works.
If not, it doesn't work.
If it does, you may need to replace the original stick with the same stick that you are trying to use now.
Use this site as a guide.

Hi guys, i have installed 2 sdrams pc-133 512mb,together 1gb, but yhe bios and the system shows me only the half memory,whyyyyyyyy

Are you sure that both sticks of RAM are properly "seated"?

How much memory is found when only one stick is used?
How much memory is found when only the other stick is used?

Which motherboard? Some very-old motherboards only support a maximum of 256MB per slot.

How many memory-chips are on each stick of RAM?
If you have purchased "high-density" memory (small number of memory-chips),
and your motherboard only supports "low-density" memory, then only 1/2 or 1/4 of the actual RAM will be used.

My pc was working fine with 128 + 256 ram. few days ago it didnt was restarting automatically. then i removed 256 ram and it booted normally.means pc works normally with 128 ram but not with 256...

i guess u have 2 different RAM cards in the RAM slots....
the main issue is both dont work together...the primary reason is compatibility....or one of the RAM cards have worn out...
u must use exactly similar kind of RAMs in both slots....
i suggest u use one 512 MB if your motherboard supports....
RAM technology has advanced so mush that you wont get RAMs for old PCs (motherboards) u decide...
pls revert back...and kindly leave a feedback and rating for this will help me move to Guru" here from Expert at Fixya....

What kind of memory can i add

go by the law, youre only as fast as your slowest stick of ram, and PC2700 is about the most expensive ram out there.. old ram that is...
if i were you, sell those two, and buy yourself a stick of 512 pc3200..
i mean think about it mathwise...
if you go from 400 mhz ram
to 266 mhz ram
your going down in speed 33 percent...
sell em! =]

My biostar P4M800 Pro-M7 only shows 1gig of ram, but i have 2gig... Wat could be the problem?

Are both chips identical ? if so

Take out the ram and replace it one stick at a time in the socket 0 or 1

If both sets of Ram work then check your instruction book on the motherboard and see what is the maximum ram it will take .

Get a copy of Memtest86+ from
and run it on both chips , that will show if there is any errors on them.

Radeon graphics card and 3rd RAM slot conflict

I thought this board looked familiar to me. I recall some rules for the memory cards. Do all your memory cards meet this requirement:

Supports up to 3GB PC1600/2100/2700/3200* DDR SDRAMs

If you are using DDR 400 you can only use 1 slot.

What kind of memory are you using?
