A co-worker just received a few memory & gave me 2 of them (2GB x 2) - I am wondering if they will work on my computer:
The memory are: CORSAIR XMS2 4GB PC2-6400 DDR2-800 Memory Kit TWIN2X4096-6400C5.
My computer info:
Will the above mentioned Corsair memory be good for my computer?
If so - can I just remove the memory in my computer & replace them with the Corsair?
I don't know if mix & matching will work as the ones in my computer are 667MHz & the Corsair are 800MHz.
I am planing on upgrading my computer - but currently as all of us are - short on cash.
Thanks in advance.
Solved! Go to Solution.
My 530s came with 800MHz memory and I have upgraded it to 4GB.
The Owners Manual 530s says:
Processor type: Intel® Core™ 2 Duo processor
Intel® Pentium® Dual-Core processor
Intel® Celeron® processor
Level 2 (L2) cache At least 512 KB pipelined-burst, eight-way set
associative, writeback SRAM
Type: 667-MHz, 800-MHz DDR2 SDRAM
Memory: connectors four
Memory capacities: 512 MB, 1 GB or 2 GB
Minimum memory: 512 MB
Maximum memory: 4 GB
Your post says "2 X 2GB Dimms" and later says "Memory Kit TWIN2X4096-6400C5". Is it a total of 4GB or total of 8GB?
Your system Maximum is 4GB. It can take 4 X 1GB or 2 X 2GB, but won't take a single 4GB Dimm.
According to my manual, I would check your manual in case it is different than mine, the 800MHz memory should work for you. I have read that you can mix the memory but it is better to use the same or matched pairs. If you are going to change it replace both Dimms.
You can also trying checking at the Memory manufactorers websites, like:
Corsair memory configurator
Maximum Memory » 4096 MB
Expansion Slots » 4
CPU Information » Intel Core 2 Duo
Other Details » Intel G33 Express, 800 FSB, Intel VIIV Technology
This indicates you should use the 667MHz, but it is wrong for my computer.
I use a System information program called "SIW", you can download it free from:
It doesn't install on your computer but you will need to 'allow' it to run. It will tell you alot about your computer system information.
Download it. Un-zip ( if it is zipped ), click the 'siw.exe' file, click "allow" in the pop up window.
It will check your system, after the full page comes up, expand 'Hardware' then click 'memory' it will tell you in "memory Summary":
Maximum Capacity (mine is 4096 M Bytes)
Maximum Memory Module Size (mine is 2048MBytes)
Memory Slots 4
And alot more infomation. If your "Maximum Memory Module Size is 2048MBytes" then your new 2 X 2GB Memory Dimms will work.
The type and speed of memory your computer can use depends on the CPU and mother board. So you need to confirm your system will handle it.
You can also check some of the other manufactorers websites some have 'Memory scanner tools' that will scan your computer and tell you what specs will work on your machine.
Try Crucial website:
I just checked this site and by slecting - Dell - Inspiron - 530s it says 667MHz, and I know mine uses 800MHz.
Try the download 'Memory scanner tools' it should tell you if it can use the 800MHz.
For me the best way to check is use the "SIW" tool mentioned above.
If you decide to change your Dimms to the 2 X 2GB, take the old ones out and put the 2 new ones in the same slots. A 32 bit OS can only use a maximum of 4GB memory.
After you install 4GB of memory Vista will say it has something like 3.5GB memory (may be different on your machine), I have read several debates on this issue, but from what I can tell some hardware will dedicate some of the processor addresses for its use leaving less than 4GB (processor adresses) available for other resources like memory. I think 3.5GB is better than 3GB and for the price of memory these days I can live with it.
Hope this helps,
Just found this thread, it explains the "missing RAM" issue.
Quote from Mr._Pseudonym:
"The processor must also communicate with other things, such as the graphics card, sound card, input/output controllers for the keyboard, mouse/touchpad, optical drive, hard drive, USB and other ports, and so on. Since the range of addresses used by these must exist withing the 4,294,967,296 address space, the whole range cannot be used for RAM."
I have seen other brief explanations but this one explains it better, Thanks MR.Pseudonym.
Inspiron 530s, Intel Core2 E7200, 6 GB DDR2 800MHz, 500GB SATA II 7200RPM, 22" Widescreen LCD w/2 MP Webcam,Radeon HD4650, Windows 7 Ultimate 64bit, eSATA port
Dell has shipped several versions on the 530s system.
The following applies to the standard 530s system:
I have been running a 530s system with 6GB RAM. I can confirm it is addressed and utilised by 64bit versions of Windows Vista and 7. There is no point having more than 4GB RAM in a 32bit system as 32bit cannot address more than 4GB.
Hope that helps.
