January 30, 200818 yr Had 512mb of PC3200 in this PC, running at normal 200mhz.But when I pop in another 512mb chip with very similar timings it drops down to 166mhz.I tried swapping the chips into different slots, tried disabling most of the "extra" stuff in BIOS like Cool n quiet, spread spectrum, etc. also tried manually setting different timings (it autodetects at 2.5 so i tried forcing it to 3, etc.) all to no avail.Any ideas? I haven't tried adjusting voltage yet...it's set at 2.6v.
January 30, 200818 yr It would help if you told us what RAM you have and the model/brand of your motherboard .
February 16, 200818 yr Author my el cheapo MB didn't like single sided RAM being mixed with double sided RAM. i hate new memory.
February 17, 200818 yr So it was the chip count, e.g 16, 8 or 4 chips... I presume you needed the 16 chip version? VIA chipset?
