[badsilver696]

i have a pc running windows xp, i have a 512 memory installed in my pc, the memory it has is a 512mb sdram pc133 and recently want to upgrade to a 1 gig went to 4 all memory did a system scan on my computer and they recommended a 1GB DDR-266 (PC2100)i notice that is not a (pc133)is that a problem or is this a better choice , after all also went to crucial memory and same thing they recommende prety much the same thing should i trust them, ???? your help will be appreciated , thanks ...

Crucial's RAM recommendation should be good because it's based on either your computer's or MB's make and model.

Newegg also has a Ram Recommendation page

Hi there,
PC133 is a completely different animal when compared to PC2100 (DDR266) The keyways are completely different.
You may however, have one of those change over boards that had both slot types.
Like the Elite ECS K7S5A or Jetways V266A/B
Perhaps if you could slip off the side panel and post back with motherboard model etc

Just found out that i have the wrong memory, for some reason i got the 1g (pc2100)ddr266 recommended to me when i did a system scan from 4 all memory .com i have never had a problem like this turns out that I have installed at thie moment two sdram 256mb (pc133)and now i need to rexchange the memory i got by mistake , heres the problem i need a
1 gig (pc133)just check 4 all memory .com for them and i got this

whats the difference between CL2 and CL3 and registered and low density or gigh density , will it make a difference which one i choose???? please help... Thanks for all of your support and advice I would of been lost if it weren't for you guys... once again thanks....

CL2 and CL3:
CL is short for CAS Latency. Search that term if you want to learn about memory design, but basically, the lower the CL number, the faster the memory.

ECC (Error-Correcting Code or Error Checking and Correction, depending on where you read) Memory: memory that detects and fixes single-bit errors. Usually found in servers and usually registered. Requires motherboard support to be effective.

Density refers to the number of modules on a memory stick. Some motherboards will not support high-density memory.

Google some of the terms you are asking about and you will find many sites that will explain them in-depth.

Having said all that, you will have to figure out if your motherboard will support 1GB memory sticks. We really can't tell you what memory will work with any real guarantee without knowing either the motherboard manufacturer's name and model number, or the make and model of the system.

You will most likely need unbuffered, non-parity memory. In your list above, the first two are likely candidates (1GB, SDRAM, PC133, CL=3
128Meg x 64, DIMM, 133Mhz, 3.3v) but again, does your motherboard support that amount of memory per memory stick?
