Hi. i have a P4 2,0 that came with 2x 256mb (pc2100) sticks. I bought another 512 (pc2100) to make 1 gb!! I'm having sudden reboots and think this is due to the new ram!! I think i found the problem but want to be sure!? I don't know if they (2x 256mb) are double sided or not. I mean there are on both sides 4 'black things', so a total of 8!! I thought it would only be double sided if both were 8 on each side!? Can anybody tell me if they are single or double sided!? 2x 256 - elixir m2u25664DS88A0G-75B mobo: Aopen AX4g Pro (only supports 2 double sided dimm)

Hi more info here http://www.elixir-memory.com/sup_name_rul_2.asp looks like your chips are quite old, 1st revision. Aopen isnt mentioned in their list of compatible mobos but doesnt mean much.

To answer the question - double-sided means double-sided. That is, chips "little black thingies" on both sides of the memory stick. :0 :) WILL POST FOR FOOD.

Hi 1stepbeyond, i visited elixir's site and already saw the 'Module Part Naming Rule'. I did not say anything about double or single or am i missing anything!? But thanx anyway... And zenith thanx for your reply...i didn't know for sure....but thanx for your input!! (and to answer your question 1stepbeyond: my pc is about 3-4 years old)

test your RAM with memtest86 http://www.memtest86.com/#download0 This space for rent

Hi lol sry i meant the revision numbers are 'old', not your pc !! ie the numbers you gave , & the elixir web site dosnt help much, could be a faulty stick check jam's link, its been long day!

Hi, i don't think it's the ram! My mobo doesn't support 3 double sided ram sticks, so that's why i asked if the 2x 256mb were double sided or not...together with the new 512 it probably doesn't work right (under heavy load, like photshop)!! I think i'm gone rip my dad's 2x 256mb (single sided) out and check if that will do the trick!? If not then i'll check the memory with memtest86!!! thanx for the reply's...
