I am wanting to upgrade my ram from x2 512 to x2 1gb i was wanting to know if the Kingston 2GB DDR2 667mhz/PC2-5300CL5 non ecc 1.8v would work fine on my computer mother board is an L4S5MG/651+ and says in book it can accept DDR 200/266/333 SDRAM unbuffered 2.5v 184pin slots max 2GB, what does all that stuff at the end meen CL5 non ecc 1.8v mean, also how easy is it to overclock this ram and how safe.

If your manual states that it can accept DDR 200/266/333 SDRAM, then the Kingston RAM will not work - that RAM is DDR2, which is incompatible with older DDR1 motherboards.

your motherboard will accept PC2700 DIMMs like this.

• CL5 means that the RAM has a CAS Latency of 5 cycles. Lower figures are better. CL2 is the lowest you can get.
• ECC memory has built-in error correction capabilities. It's consequently more stable, is common in servers and is more expensive. Non-ECC memory is cheaper and more common in consumer-level desktop machines.
• 1.8V is the voltage that the RAM requires from the motherboard to operate properly. The DDR RAM in your machine requires 2.5V to run at 166MHz (DDR333). It is sometimes possible to overclock RAM, depending on your machine. When this is done, it's often necessary to raise the voltages somewhat to keep the machine stable.

hi there thanks for the response, your right sdram is what is stated in my mother board handbook but when i go to that website crucial and have it scan my machine it comes up with ddr dimm pc3200 512mb x2 i am so confusd is there a difference between ddr2 and ddr is ddr sdram???

DDR2 has 200 pins (the gold bits that you insert into the slot on your motherboard), and operates in the 1.8V range at frequencies of up to ~500MHz, whereas DDR1 (what you have in your machine) has 184 pins, operates at 2.5V at speeds of 200MHz.

DDR SDRAM = Double Data Synchronous Dynamic RAM

DDR2 = Double Data Rate 2. It's an evolutionary design change to the DDR standard.

The most important thing to remember is that DDR2 is not compatible with your machine.

I've never used the Kingston scanner, so I don't know how it gets the information it gives you. What I would suggest is this:

• Download CPU-z
• Double click on the executable (obviously, scan it with Anti-Virus software first).
• Wait a few seconds, and a dialog box will pop-up displaying all kinds of information on your processor and memory - it will give you not only information about what your RAM says it is capable of, but what it is actually doing as well.
• take screenshots of the tabs*, post them up here, and someone will be able to tell you definitively what RAM you should buy - PC3200 (DDR400) is what you want if your system bus is actually able to run at 200MHz. However, if your system bus is running at 166MHz, your RAM will be performing at PC2700, not PC3200.

*To post a screenshot, follow these instructions:

1. Hit alt+Print Screen with CPUz as the active window.
2. Open up MS Paint
3. Hit CTRL+V to paste the screenshot into the Paint window.
4. File > Save As JPG.

After that, you have two options:

• Go to Imageshack.us or pix.nofrag.com and follow the instructions there to upload the image to their server, then paste the url of the image into [img][/img] tags.

Alternatively,

• you might be able to host the images on itsallpc by attaching files through the "Manage Attachments" dialog below the text entry box.

Hi there i attached screen shots so what would you recom on the ram i am looking for the best in 2 gb
