Hey, Thanks so much! I've been looking for a good deal on memory for a while now. Thanks again

[DarthVader]

My computer will not work with it!!

The speed has to be 300Mhz or higher for mine, I've seen new memory chips that run 800Mhz. These must be real fast!!!

So... anyone for 133Mhz memory cheap?

[twodogma]

It is good buy.But does anyone know what NON ECC means?? I have a 650mhz system that uses DIMM memory.Will this work with my system ????????????

you can check your specific make and model at

ECC (Error Checking and Correcting) performs "double bit detection and single bit correction." This means that if you have a single bit memory error, the chipset and memory will find and repair the error on the fly without you knowing that it happened. If you have a double bit memory error, it will detect and report it. Using ECC decreases your PC's performance by about 2%. Current technology DRAM is very stable and memory errors are rare, so unless you have a need for ECC, you are better served with non-parity SDRAM.


If you already have a PC and are unsure which type you have, count the number of small, black, IC chips mounted on one of your existing DIMMs. If the number of chips is evenly divisible by three, then you need ECC. If the number of chips is NOT evenly divisible by three, you have non-parity memory.

Thanks ILUV2SHOP.That was very helpful.That's an excellent price.When we ordered an upgrade from our PC manuf.,it was 129.99 for 128mb.I really got ripped off.Oh well,you live,you learn.

I just saw this and thought ooooooo goodie.
Well it looks like they raised the price to $29.95. Although still a good price. Shipping is $5.05 which makes it an even $35.00.

Best to just go to memory sites and determine exactly what kind of memory you need. If your PC brand/model isn't listed, the next best alternative is to look at what you have in there now, search the web for the part number on the memory card, and get the same thing.

memory is tricky. It gets even more complicated than even iluv's explanation (there is non-parity, parity, and ecc, for example, plus sdram, registered sdram, rambus, and a billion other factors).

And if you get the wrong thing, even by just a small difference, chances are it either won't work, or will show up as a smaller amount of memory.

Here's the simplified rule:

If you have an Intel Pentium III and/or an Intel Celeron and/or an AMD Athlon (below 1ghz)and/or an AMD Thunderbird, then your computer is 97.5% compatible with SDRAM technology.

Even if you computer says that it needs PC100 ram only, PC133 ram will work just as well performing as a PC100.

ECC/non-ECC is not important unless your computer is built to perform lots of calculations. Otherwise your CPU can do the error-checking. Most computers have non-ECC ram.

If your computer utilizes an Intel Pentium I/II or older and/or an AMD K6/3 or older, chances are your technology is too outdated to use the ram.

Notebooks require other kinds of memory.

RDRAM or Rambus memory operates at 600/800mhz. This ram is for Intel Pentium IV only. Do not purchase SDRAM if your computer is a Pentium IV.

Very very few computers use DDR ram. These operate at 266mhz. Most commonly found in AMD Athlon systems.

Remember the mhz of ram is a complete different measure of speed from your CPU. There are no such things as 1.7Ghz ram or 300/400mhz ram.

Anyway, this is a superb deal for Kingston memory. Personally I would go for the 256mb DIMM: [Only registered and activated users can see links. Either login above or Register Now]

If you don't know how to install ram in your computer, I recommend letting someone who knows to advise you on your purchase.

And remember to consult your computer manual to confirm the type of ram your computer uses. (Look in the index for Upgrades or Ram) The ram you can use ultimately depends on your motherboard.

CPU Speed
50-500mhz: Pentium I/II, AMD K6, AMD K6/2, AMD K6/3, Cyrix --- FPM/EDO memory
500mhz-1.33ghz: Pentium III, AMD Athlon, AMD Thunderbird -- SDRAM memory
1ghz-1.4ghz: (few) Pentium III, (most) AMD Athlon -- DDR memory
1.3-1.7ghz: (99%) Pentium IV -- RDRAM memory

This is not perfect as I am writing this off the top of my head. Feel free to ask any questions.

In general, I agree with the post above - this is a great deal (take advantage of memory oversupplies when they happen, let others pay more next year!), and in general his categorization is correct.


However, two of my 4 computers violate the rules of thumb (which are generally correct from my quick reading of them), so the best (really only) bet is to either buy and be prepared to return it, or, more recommended, confirm your PC's requirements from the pc's documentation or from a web site (either the PC makers or a memory maker) before you buy memory.

After all, we haven't even gotten into voltage levels and size/organization issues (can your PC accept and recognize a 256Meg module?).

Don't get stuck having to dump your memory module on ebay for a fraction of what you paid for it when you discover you got the wrong part.
