I have a custom computer. My computer specs are attached, and are also viewable here:: My Computer Specs Here is my BIOS info, according to esupport.com, I have the latest BIOS: BIOS Type: Phoenix-Award BIOS Date: August 31st 2004 BIOS ID: 08/31/2004-KT400-8235-SV400C-00-None BIOS OEM: SV400 08/31/2004 - 6.00 PG Chipset: VIA 82C3189 rev 0 SuperIO: ITE 8705/SiS 950 rev 2 at port 002E Manufacturer: VIA Technologies, Inc. Motherboard: KT400-8235 My motherboard manufacturer, Syntax, is out of business. I just installed 3 x 1GB PC2700 333MHz DDR Memory (1 sided) into the 3 slots on my main board. The motherboard manual says it supports, "DDR up to 200/266/333/400 MHz DDR SDRAM memory module. Accommodates three unbuffered 2.5V 184-pin slots. Each slot supports up to 1BG with a maximum capacity of 3GB. I tested each memory stick independently using Memtest86+ V2.01 Memtest86+ - Advanced Memory Diagnostic Tool. Each stick passed 11 passes with flying colors. I tried every combination of memory/slots on the main board and the maximum the BOIS picks up is 2GB. Which means it is not reading from 3 slots, only 2 at a time. It doesnt matter which two. All slots work, just not all 3 together. I have two identical boards with the same BIOS version experiencing the same issue. How do I get the computer to recognize all three slots and all three memory sticks simultaneously?
Regardless of what Everest says, does your bios on boot show the whole 3Gbs and does windows show the whole 3Gbs.
