2.0 out of 5 stars Why you might want the 256S100 instead, March 20, 2003

By	anonymous - See all my reviews

A couple of people have complained about this card having high density chips, which are incompatible with their system. This happened with my Oct. 2000 Dell Dimension 4100. According to the person I spoke to at PNY's technical support (1-800-234-4597), since the high density 133MHz chips are *not* downwards compatible to 100MHz machines, but the low density 133MHz chips are, the 256S100, despite its name, actually contains 133MHz chips. (I suppose it is cheaper to inventory this way.) And they are low density. So the 256S100 is the correct choice for someone like me whose specs call for a 168 pin DIMM of 133MHz SDRAM, but whose computer cannot handle the newer high density chips. What seems to have happened--which I learned from Viking Components tech support as I was comparing with their cards (compare their DL3264M with their PC13332X64-CL3: the specs are the same, and sometimes the cards are identical, but the second is guaranteed to be 16 low density chips, whereas the first may or may not be 8 high density depending on what they have when they ship) is that if the card makers have them, they put high density chips on their cards; otherwise they put on the low density. This of course--and inexcusably--makes the compatability information on the card-makers websites obsolete, and leads to problems like those seen in some other reviews, which I also experienced.

So I would like to suggest getting the 256S100 if you have any doubts about whether your computer can take the high density chips. The 256S100 is indeed working in my computer, and my BIOS claims it is 133MHz, despite its name. But what you should really do is call tech support and make sure your computer can handle the card before you buy.

1.0 out of 5 stars If you don't have a new computer beware, October 10, 2002

By	IVE - See all my reviews

I have a 800MHz Pentium III. This computer is not the newest computer, but it is not an obsolete computer either. I bought 512 MB (2 256dimms) of RAM and to my surprise, the computer only recognized half of it! The problem is not the computer, in the PNY web site there's a warning about using this "high density" memory with old (1999 and older) motherboards.

When I saw the following, I knew this has happened to a lot of people before me.

From the PNY web site:

7) Why does my system only see 25% or 50% of the total memory installed?

Answer

Older (Pre 1999) systems may require an older memory module design that PNY and most other manufacturers no longer make. Some of these modules are still available, but they are not generally easy to find. The modules that we now manufacture use a high-density construction. These new modules will not work properly in your older system. If you have already purchased a module, and that module is not working in your system, return the module to the store where you purchased it within the time of the return policy.

If you are running Windows 98 check "MSCONFIG" to make sure that your system is not limited to a set number of megabytes of memory. Go to "Start", select "Run", and then type in "MSCONFIG". Press "Enter", then go to the "Advanced" button at the bottom, and look to see if there is a check mark in the box that says, "Limit memory to". This should be unchecked. If you make a change here, you must reboot before any changes will take effect.

5.0 out of 5 stars It's compatible with Dell Dimension 4100, March 26, 2003

By A Customer

I disagreed with ANONYMOUS' review of March 20 that this 256MB PC133 memory module is incompatible with Dell Dimension 4100. I have the same model desk top (P3 800MHZ) purchased Sept 2000 (see my review of Mar 22).This memory upgrade works so well, I just purchased a second one to upgrade my memory to 512MB. All you have to do is to open the case, plug in the module and restart the computer, check the system property, your memory is upgraded.
