You are most welcome. At the present time, those Patriots I linked would be your best bet, IMHO. However; if you do not have a REAL NEED for running 8GB's of RAM, I would suggest running only 4GB's (2x2). 4GB's is easier on the Memory Controller and easier to tune in and stabilize.

I think it would be OK to just go ahead and run your first test with them both installed...if one or both of the stix are bad...you won't be able to complete even one full test pass.

That is good news, man. By all means, remove the 2 now known good stix and test the other pair ASAP in the same manner. Make sure that they do not get mixed up with the others. Mark them in some way so that you know which stix go together.
 
You should not have to "reapply" the same settings...they should still be in effect until you change them.

Please do not take this the wrong way, Man....I'm just trying to help, OK? I'm not trying to rude or overbearing.
 
I do not want you making BIOS changes unless I ask you to do so. I did not instruct you to reapply the 1600MHz OC settings from post #6....those did not work so, I want you to forget them. I want you to stay with the above settings for now which, match the post #8-9 Template and actually work for you. We will try working our way up to a 1600MHz OC but, it is going to take some time and testing.
 
I hope this is OK with you....if not, just say so.

Kool.....have you tested the other pair of RAM stix in the black slots with the same settings that the first pair passed on?? If not, that is what I need you to do....need to get those initial tests out of the way to determine if all stix are good before worrying about whether you can get into OS or not.
 
It would also be a good idea to create your Forum Signature listing all your system components including make/model numbers....kinda like what you did in post #1 but, add in the rest of your parts like PSU etc. There is a link button near the top of this page: User Control Panel>Edit Profile>Signature and Comments.

Good deal and thank you for doing that signature.
 
Just run 1 pair for now at those same settings and let me know if you experience any problems getting into your OS or while running in it. If all is well after some testing, we'll see about OC'ing...OK??

Yeah, we are online at the sametime :) , You are rite, i installed the OS with my old ram stix,i will make the changes to the voltage settings in the bios and make sure they persist before re-installing the OS.
thanks for your time and Advice

Hi Jeff,
        I was not able to make a clean install of ubuntu, i tried to do it but there is no option to re-install over existing ubuntu one.So i installed windows 7 64bit, the installation went fine and was able to reboot without any problems with windows, and with the same bios settings as theRAM's passed.I guess the system is stable now with current settings, will wait for your next instructions on plugging in the other 4GB ram and OC settings.
thanks!

Hi Jeff,
   I made the changes u recommended and i was good for a few reboots, went to the OS fine but crashed a couple of  times, it wont load OS, will try a few more times to see if i get this same  behaviour ,One more thing i noticed is some applications dont open even after i get to the OS, i get this message "Real PLayer has stopped working Windows is checking for a solution" when i try to open real player,
in my previous settings (post 9 settings) with 2 ram stix , everything is working fine.
with below bios settings the sysetm is not stable.the ones in bold are manually entered.

made these voltages, when i reboot the system just hangs and i see 11 code on the motherboard, so i restarted again,
i see this message now
Warning! Now System is in Safe Mode.
Please reset CPU or Memory Frequency in the CMOS setup.
thanks!
