I have a 1.7 celeron with a m925 motherboard and antec 400 watt power ss running ME. I can only use one of the two ddr slots at 256. The other one causes crashes. Both slots work fine, both ddr's work fine. Just not together. They are crucial pc2100 ddr 256mb 266 mhz cl 2.5. I changed jumper jp1 to open 1-2, and short all j2a/b/c/d and j3a/b/c/d. any ideas?
