PLZ help me RAM useable is 2.7GB out of 6GB

I have lenovo THINKPAD T430 and the ram is 6 GB ....... Usable ram is 2.7 GB help me PLZ View attachment 94105 View attachment 94106

 

You're using a x86 or 32 bit version of Windows 7, which only does up to 3GB or so of memory. You'll need to install the x64 version of Windows 7 to use more memory.

 

so if i installed 64 bit ill get the full 6 GB

 

Not the full 6GB, but close: some of the RAM is reserved for HD 4000 integrated graphics (and then incrementally allocated as needed).

Install the 64-bit version of Windows 7.

 

Your T430 is a current machine with an i7 cpu. You put in a different sized 2nd stick by yourself, right?

Your cheapest option is to use only the one stick of 4GB that you already have.

Another cheap option is to buy a 2nd 2GB stick with same speed and latency as the 2GB stick that you already have. That gives you dual channel RAM performance which is better than single channel or 2 sticks of different size, see: http://forum.notebookreview.com/lenovo/713260-q-thinkpad-ram-gpu.html

If you stay with Win7 but upgrade to 64 bit, it won't be cheap. Money for the 64 bit upgrade plus you'd likely want a 2nd 4GB stick of memory.

If you upgrade to Win8/64, that might be cheaper but then you'll have some annoying software incompatibilities.

What you pay for with Windows is the ID. I'd want an ID that would work with doing a fresh install of Windows. Meaning I'm not sure what you get with an upgrade ID.

 

The OP's issue is "physical memory addressability," not how many RAM sticks or whether those RAM sticks are the same. Also, the issue is not related to ỉ3, i5 or i7 CPU.

In simplest terms, if one wants the OS to address more than 4GB of RAM (no matter how the RAM is configured), one must use a Windows 64-bit version. This applies to both 7 and 8.

 

As Zaz and Kaso said, you need 64 bit to use more than 3+ GB ram.

You can not upgrade from 32 to 64 bit. You have to do a clean install. I see you have Win7 Home Basic, so you can clean install to 64 bit HB using the same key. The key should be on your PC (look on the bottom somewhere) but you can use something like Magic JellyBean to get it also.

If you have the OS disks you should be able to choose custom installation and choose 64 bit. If you don't you can follow the instructions here: http://forum.notebookreview.com/win...-digitalriver-windows-7-sp1-13-languages.html and download and make your own disk.

As long as you have the product key, it is free and legal to do this.

Back everything up BEFORE you clean install, so in case anything goes wrong, you can revert back to your current system.

 

Nice response. You're pushing him into the deep end, I hope he can swim.

Cheaper and easier to stay with 1x4GB stick of RAM, or 2x2GB sticks of RAM.

Anyway, Hearst has this in his Win7 writeup:
>"Step 3: If you happen to have your own Windows 7 Retail Product Key on hand then you can skip this step.

* For those who have Windows 7 Preinstalled by the OEM regardless if it's 32 bit or 64 bit version - now is the time to back up that Windows Activation Status.

Download ABR Backup & Restore and extract the contents (create a new directory called ABR in the process). Run the "activation_backup" application and it will create two new files that contains your product key information and OEM certificate. Copy those including the whole ABR directory on to the USB Flash Drive and proceed to the next step.

* If you happen to have a 32 bit version of Windows 7 that came as part of a Retail Upgrade and want to transfer that to a Clean Install of 64 bit version of Windows 7 then use the Token Restore application instead. This will backup the upgrade Activation Status and transfer it over to the Clean Install. Extract the application (create a new directory called Token Restore in the process), run the application then click on Backup and select the same directory and it will proceed to backup your activation status for use the next time when you restore it. Copy the whole Token Restore directory on to the USB Flash Drive and proceed to the next step."<

 

Again, what does the OP's issue have to do with "1x4GB stick of RAM, or 2x2GB sticks of RAM"?

The same Windows 7 Home Basic COA can be used for either 32-bit or 64-bit installation. If the OP would like Windows 7 to address more than 4GB of RAM, the advice is for the OP to install Windows 7 Home Basic 64-bit using a legally downloadable ISO image. No "upgrade money" involved.

The OP's T430 has 6GB of RAM. There is no point in touching this.

In fact, the OP already indicated understanding with a "like" to ZaZ's reply.

 

Why don't you let the OP speak for himself?

 

Well, he did:

 

The OP has to bear in mind that you cannot simply upgrade from a 32 bit OS to a 64 bit OS, a clean installation will be necessary which will wipe out any existing data so back up any important files, drivers and applications that you may need before performing this procedure. You can however use the same key, for x86 to x64 activation transfers you may need to use an application called Token Restore or use an alternative called Advanced Tokens Manager which is more user friendly.

 

I agree with Kaso, his memory is fine.

By the way he can legally use the same key for 32bit vs 64bit Win7.

So if he can just get his hands on a 64bit install media is all he needs.
