ea25 Posted October 17, 2009 Share Posted October 17, 2009 Hello guys, first post here :D: So I recently bought this new rig consisting of Lynnfield i5 750, P7P55D mobo and of course Corsair dual kit CMX4GX3M2A1600C9. Booted the system and it went fine, rebooted after installing some software and it went fine, rebooted and led on mobo lit up (meaning POST didn't succeed). Took out sticks and replaced them, same thing again. Switched off from power supply and rebooted and once more everything went fine, rebooted and all of a sudden BIOS + Windows recognise only 2gb out of the 4gb :bigeyes: Anyways i continued with this rebooting/POST failing/POST succeeding but 2GB out of 4GB recognised/everything works fine! pattern for about three days up to the point of driving me mad :bigeyes: The really bizarre thing is that there is no pattern at all in fact. Sometimes everything works fine and sometimes some other failure crops up but in a random fashion. Today it passed my mind to take off the sticks once more and test them one by one. So I started with first stick, boot 1 went fine, boot 2 went fine, boot 3 with intel burn test went fine etc etc etc..... up to the point that I overclocked rig up to 3.8Ghz and it was perfectly stable and still is. After about 5hrs of testing took out stick one and replaced with stick 2. Boot 1 went fine, boot 2 started same problems again. So stick 2 is definitely the problem. The thing is that i ran MemTest on stick 2 for 4hours and it didn't find one single error, however i than rebooted and POST got stuck on the ram led once again i.e. back to square one I think this is a really bizarre situation, I'm now really tired of messing around and would appreciate some help. I'm suspecting a defective stick but cross-fingers prob might be solved. Link to comment Share on other sites More sharing options...

ea25 Posted October 17, 2009 Author Share Posted October 17, 2009 Thanks for the quick reply. May I RMA only the defective stick so that I can use the other one to temporarily be able to use my pc ? And how does rma really works, like what would be the costs incurred ? (I leave in Europe btw) Link to comment Share on other sites More sharing options...

ea25 Posted October 19, 2009 Author Share Posted October 19, 2009 Before RMAing I have some questions to ask. 1) Should Corsair test my stick and it passes memtest86 would I still be entitled to a new stick? 2) Approximately how many days does the whole RMA process takes?
