    Oh, this laptop is a IBM Thinkpad T30 Model 2367-GU3

    They are the same memory brand chips, both are 512mb, pc2100. I am thinking that one of the slot the additional is not working. It recogizes only one stick.

I have the same problem and the only reasonable solution is to send the unit back to fix the motherboard. I bought two 512 MB modules, installed them both for a total of 1 GB, only to have the machine recognize 512 MB. After swapping the modules around and even depopulating all memory, I found that the slot closest to the front is not working. When I populate a module only in that slot, the BIOS beeps a memory error code when powering up the machine. I've read other posts that claim this is a latent defect in this model. Some folks have even had their T30's degrade to where the once-working front slot no longer works. Hope this helps.

How many RAM slots do you have? Are they coloured differentlly? For example 2 blue, 2 black. If so.. Put one 512 MB DIMM in either a black one or a blue one, and the other DIMM in the other slot of the same colour.

I hope this solves your problem.

Greetings,

    Oh Sorry, I misread. The above isn't appropriate for a notebook. Check if they are both connected properly.Are they both of the same type?

    You should try to switch 'em. Use the memory bank that was used with your 256 MB DIMM. Test both on that one. If they both work and you are completely sure you installed them both correctly then the slot is defective. Otherwise one of your memory modules might be defective.

My system says, (RAM) radon access memory low cpu intel (r) pentium 4 cpu, version 2.80 ghz. RAM 256 mb. What can I do to resolve this problem. Dell 4700 dimension


Windows XP requires a "bare-minimum" of 128MB of RAM, works "OK" with your 256MB of RAM, if you don't open too many programs at the same time, and if you close/re-open Internet Explorer about once an hour of usage.

But, Windows XP would be _much_ "happier" if you added 256MB or 512MB of RAM, because it is telling you ("available random access memory is low") that it is using all the RAM.

Add more RAM -- your computer will run much better.

Hi, Replacing my 256mb ram (1 slot) with 1Gb (2x512). The computer would not boot. Removing 1x512 memory the computer works fine. I put my old 256Mb back with the 512 Mb and the system only reported 256Mb....


Is the speed of the RAM the same mixing PC 133 and PC100 ram can cause problems working together. Also it sounds as if your board will only upgrade to a maximum of 512 MB total.

Adding memory to a a75-s211


How much memory did it have before you removed the 256Mb RAM?
If it had 756Mb RAM then the memory in the laptop has 512 Mb plus 256 Mb RAM modules, the 256Mb in the slot you can see and possibly 512Mb in a slot under the keyboard or soldered on the motherboard.
Therefore by removing the 256Mb and replacing with 1Gb memory module will give you a total of 1.5Gb

Beeping noise after installed memory on ecs motherboard L4S5MG


Some older computers, like mine, have a maximum memory they can handle. This one happens to be 1 gig, but yours may be less. Do you have an older computer? Yup, you do. As seen here, the maximum supported ram is 256. I'm sorry. Please rate.

Sharp Actius AV18 does not recognize added 512MB PC2700 RAM. The machine still only sees 256MB. Is there something else I need to do?


I assume the laptop had originally 256Mb RAM and you put 512Mb RAM in a the spare memory slot and you expected to see 768Mb of memory, is this correct? Try removing the 256Mb memory module and insert the 512Mb memory module and see if the laptop boots up with 512Mb of RAM. If it doesn't boot up then the RAM is either incompatible or faulty. Try using RAM modules from the same manufacturer.

Incorrect value on ram


Hi,

Even if the new memory is 256mb, the motherboard will not read it as such but a max of only 128mb. Alternately, what you need is to get is another 128mb SRAM rated at 100/133 MHz. Sorry to say but yours is a common problem when newer memory are fitted to a relatively not so recent machine.

Good luck and kind regards.
