They both have the exact same size ( 4gb) and the exact same frequency (1333 Mhz ) . I`m talking about timing here altough they are both CL9 .

I don`t know about that , i made a lot of computers with different models/brands of memory as long as they had the same specs , and i didn`t run into any problem untill now . I even mixed different Mhz . I think my motherboard is forcing the wrong timings on auto but i don`t know what to set myself .

First of all this is my rig : MB : Asus P7H55M-PROCPU: Intel i3-540 HDD : WD Caviar Black 500 GbGPU: Nvidia GTX 650 1 Gb OC editionOS: Windows 7 x64Current RAM : Silicon Power - sp004gbltu133v02 4gb DDR3 1333 Mhz Now my problem is this . I bought a new stick of ram ( Kingmax flff65f-d8kq9 4Gb DDR3 1333 Mhz CL9 ) and i can`t make it to work with the one I allready have . Actually I can`t make it work at all with my motherboard . If I put it along with the one I have , it just freezes in boot screen , unless i put the old one in the first slot and the new one in the second , then it just restarts when windows tries to load . If i I put the new one alone i get random BSOD`s whatever i do . Now , the differences I noticed between the two sticks are that one is double sided 256mx8 16 chips while the other one is single sided 256mx8 8 chips (kingmax) , and i noticed some differences in bios when it comes to timing . Another difference is the REF cycle time ( new one has 200 while the old one has 108) and the timing mode (old one has 1N , new one has 2N ) . Is there anything I can do to make them work together even at a lower frequency ? I don`t want to mess with the timings without knowing what i`m doing . The ram is tested on another pc with memtest86 and it has no error and work fine . If there`s any information you need i`ll probably watch this topic every 5 seconds as i`m trying to do this for almost 2 days . Oh and by the way , the ram is used , i can`t return it and i have no money to buy another stick or kit , because i`m unemployed at the moment. Thank you .
