Gman, I went back and searched for the link you sent to me and looked at the price of this memory as opposed to what I paid today. Can you go here for me and tell me if $76.00 is the price for two sticks of memory, each being 1 gig? If so I really got ....**. Unless there is some kind of big difference between the two brands. http://www.newegg.com/Product/Product.aspx?Item=N82E16820141308 Christine ----- Original Message ----- From: "Gman" <gman.pctt@xxxxxxxxx> To: <pctechtalk@xxxxxxxxxxxxx> Sent: Friday, July 25, 2008 3:28 PM Subject: -=PCTechTalk=- Re: help,bluescreen yikes From the specs shown about your mainboard; Memory Architecture Dual Channel DDR SDRAM Memory connectors Four Memory capacities 128-, 256-, 512-MB or 1-GB Minimum memory 128-MB DDR SDRAM NOTE: Between 32 and 64 MB of system memory may be allocated to support graphics, depending on system memory size and other factors. Maximum memory 4 GB Memory type PC2700 (333-MHz) or PC3200 (400-MHz) DDR SDRAM (non-ECC) Translated, this means that you have 4 slots that can handle up to 1GB of DDR (dual data rate) non-ECC memory each for a max of 4GB. The sweet spot for XP has shown itself to be 2GB, so the board supports that. The ideal speed you should be running is PC3200 which runs at 400Mhz. The board also supports dual-channel memory which means that you should ideally have matched pairs of RAM sticks installed into the proper memory slots in order to take advantage of that technology. Specifically, a matched set of 1GB sticks installed into slots 1 & 3 or slots 2 & 4 would allow 2GB in dual-channel mode. Any other combiniation of slots would force the board back into single-channel mode which is how it's running right now. Also, adding a single stick to any slot would also disable dual-channel, even if you already had dual-channel running. For example, a matched pair in slots 1 & 3 gives you dual-channel operation, but if you then add a single 1GB stick to slot 2, the system would then revert back to single-channel mode. Single-channel mode does not hurt the system, but dual-channel provides a lot of benefits. So, my recommendation would be for you to buy a matched set of PC3200 DDR sticks like any of the sets shown in the link below (they are ALL rated as appropriate for your Dell Dimension 4600 system). http://tinyurl.com/5mj25l Peace, Gman " --------------------------------------------------------------- Please remember to trim your replies (including this sentence and everything below it) and adjust the subject line as necessary.
