Memory voltages

[hennessy1]

I am using a 780i board with this memory
http://www.newegg.com/Product/Produc...82E16820220353
For a total of 8GB of memory.

I have 3 other systems where when I input the correct timings I leave all the voltages on auto. The only one it bumps up is the SPP voltage to 1.40v. The memory voltage is at 1.85v. I run memtest for a while and all comes out good.

I now have a 4th system with the same board and memory that when I put in the timings it also bumps up the SPP voltage to 1.40v but this time when I run memtest around 19% it causes memtest to freeze. So I did a little troubleshooting and found out that if I bump it up to 1.90v and leave the SPP at 1.40v it will go through the test fine.

I am using Memtest86+ v.4

My question is could this board just require more volts for this memory then the others or is this indicative of a serious issue?

It seems when I set the SPP voltage back to its' original 1.3v memtest goes through fine.

Your memory is rated to run with 2.1v
Why would you not jack the voltage up to 2.1v, if you are having memory stability issues?

I know what you mean. So I should just basically ramp it up to 2.1v and down the SPP voltage to its regular thing then huh?

Set the memory voltage to the rated 2.1v and the SPP voltage at stock. You should only need to increase the SPP voltage if the system is not stable.

And if so increase in 1/4 increments correct?
