I have an HP a1410n running WinXP. It came with 1 gig of ram (2x512) DDR400. I put in another 1 gig (2x512) in it to make 2 gigs. Strange thing is the BIOS now says all the memory is PC2100. I take out the new, back to PC3200. Take out the old put in the new, it says PC3200. For some reason together they run at PC2100 instead of it's PC3200 speed. They are not the same manufacturer but the RAM I put in is mid grade GeiL. The PC only has a 300Watt PS in it. It has 3 hard drives a DVD-ROM and a few usb periherals. An ATI 1600XT pci express card in it too. Is this a voltage issue where the power supply can't provide? Or is it a BIOS issue? HP supposrt has come up with nothing for me. I need your help!!! Why is my memory running slow???
Thanks in Advance!

there are 4 memory sticks in the PC 4x514. The memory is all PC3200 dual channel. Just the cas rating is different. It should run at the lower cas sspeed but not bum the speed to PC2100! Any ideas?

Your motherboard supports something called dual channel memory. The chipset in that system (Nvidia 6150) can be sensitive to what is in the different channels. Try putting the two 512MB sticks in one channel and the 1GB stick in the other. The slots should be color coded. If they are not try putting the sticks in different combinations of positions. It may just not work and you'll have to replace the two 512MB sticks with another 1GB stick.
It is a little odd that the speed drops like it does, might mean the 1GB module is bad. (Doubtful)

Hi. You could try changing the BIOS set speed from 'Auto" to 'User select'. Start slow and try it. Move up in increments. I would hesitate to increase the voltage with mixed brands. You can sometimes get better performance by upping the FSB.

the substantial section isn't the quantity used whilst idle, however the quantity used at rigidity factors. people who never use extra advantageous than 20% of their RAM ignored the factor of it. you % to apply it. it fairly is there for use. while you're seeing upwards of 80% whilst stressing it, it may be smart to enhance so which you will never be short interior the destiny.

in a mixed environment pc motherboard will assume speed of the slower memory blocks.
