>>whether or not this type of RAM would be ok in my system. Please refer to your manual that came with your motherboard. It will state weather it can handle PC133 chips. More than likely, the answer will be yes. ~~~~~~~~~~~ Peter -----Original Message----- From: pchelpers-bounce@xxxxxxxxxxxxx [mailto:pchelpers-bounce@xxxxxxxxxxxxx]On Behalf Of John Paul Mays Sent: Sunday, February 10, 2002 1:31 PM To: PC Helpers Subject: [pchelpers] A question about DIMMS Importance: High Greetings Everyone! I've just upgraded my mobo/CPU to an IWill KK266Plus-R with an Athon XP 1600+,and I currently have 384MB SDRAM (3 128MB DIMMS). I'm looking at doubling that amount by replacing the 3 128s with three 256s. The particular RAM I'm looking at is: "High Density (32x4) 256MB PC133 Memory 168pin" I'd be much obliged if someone could provide me some info and/or experience with this type of memory, and whether or not this type of RAM would be ok in my system. According to the reseller's documentation on their website about this particular memory, it states as follows: "These modules are made using a high-density 32Bit DRAM Chip. To use this module, your motherboard must be able to accept a 512 MB DIMM in each memory slot. If not, your system might only recognize the chip as 128MB". My mobo is one of the newer ones and is capable of accepting (and recognizing) a 512MB DIMM in each above its banks (3). Please advise. Thanks! /jp/ dojpaul2@xxxxxxxxx
