Hey all, some of you might recall that a while ago I had just finished upgrading my computer after some trouble with RAM. Here is my current build:
Intel Q6600 @ 2.8 GHz
Geforce 7900 GTX
Antec Truepower 2.0 550W PSU
2 x 1GB DDR800 Geil Memory
Gigabyte P35-DS4
Anyway, when I upgraded one of the memory sticks was bad (my computer would start with it and then turn off after about 5 seconds) so I just ran with one until today when I was able to go back and exchange it. Now both sticks work BY THEMSELVES but not when I put them in together. It gives me the same issue of starting up then turning off after about 5 seconds. I am extremely confused and have no idea what to do.. I have tried both separately and that works and I have tried not running them in dual channel (placing one in the red slot and the other in the yellow) and that does not work. Please help!
Thanks in advance
boot to BIOS with one stick, manually set RAM timings and voltage, then power down and install the second stick.

Yes No
Uhh, what do I set the RAM timings and voltage to?

Yes No
check Geil.com for manufacturer's recommended settings

Yes No
Okay, so the site says 1.8-2.2V and 5-5-5-15 timings. I went into my motherboard BIOS and it didn't tell me what voltage it was at it only let me bump up the voltage by certain intervals.. :S. Is it possible my PSU is not powerful enough to supply them both or something?

Yes No
Okay I managed to find one discrepancy, when I am running a single stick of RAM it says the timing is 5-5-5-18 but on the RAM the timings are written as 5-5-5-15. Would changing this affect anything?

Yes No
Okay.. A lot just happened hahaha. I loaded the optimized default settings, shut down the computer and put in the second stick of RAM. This time it got to the Login screen and I was like woop-ee it's working!!! Suddenly the display cut off and then after about 20 seconds the computer shut down. So I turned it off took out the second stick booted up with one and again Loaded the Optimized Default settings and shut down, put the second stick in and booted up. And now I am currently posting to you from my computer which has 2GB of RAM!!!!
However, I seriously doubt the stability of this setup. I think as soon as I put it under any load it will shut down. My computer is still lying on its side with insides exposed after this post I will turn it back upright and put the side back on and hopefully it will still be working.. wish me luck .
Also I think it may be that my stupid Truepower 2.0 550W PSU is just unable to handle the RAM.
EDIT: Just turned off the computer and attempted to reboot it, no dice. I'm guessing its the power supply's inability to support the second stick of RAM which means I'm in the market for a new PSU. How does the Corsair 620 HX sound?

Install one of these to see what voltage your memory is running at so you can get a idea how high or low it is.

Yes No
Would it be running at the same voltage if I put 2 sticks in without me changing any settings? Also is PCwizard displaying what the motherboard is putting in or what is actually going into the memory?
Thank you
EDIT: Voltage under SPD EEPROM (A3) is SSTL 1.8V

Yes No
No telling, it could be that the SPD on one stick defaults to a lower voltage than the other one, I,ve seen weirder thing happen. Its what the memory is running at, voltage and timing.
