I dont get it?

[Scurvythepirate]

Okay, so a couple days ago I get blue screens. No biggie and then after a shut down it wouldn't turn back on. So i take a look, everything is plugged in the power, motherboard, CPU, GPU, memory etc. I took out a memory stick and wola it worked. So my task was to find out if two sticks would work. I tried every slot and both sticks work, just not together. All 4 slots....... I just don't get it? Why wont it work.
This had been the problems of my blue screens before and I went into the bois and reset it to normal and still..... nothing IDK.
Please reply with logical answers

I've owned this computer for 4 months with Vista

It would help if you provided a detailed list of components.

What voltage and timings are you using for the memory modules and what do they require according to the CPU-Z SPD tab?

 

[Scurvythepirate]

the voltage timings are 5-5-5-18 the voltage is 1.80V.

It looks like your ram is rated at 5-5-5-18 1.9V, according to the Corsair website. Try increasing the voltage to 1.9V or even 2.0V. Use memtest86+ to test the ram for errors.

i had this same problem - combinations using 4 sticks of memory (chosen from 4x1G and 2x2G sticks) would boot once if i tried 75-100 times, but any supported combination of 2 sticks would boot every time... i found that the memory voltage sank just barely below the required level with any 4 sticks installed. Adjusting it upward very slightly fixed the problem.
