Overvolting RAM memory

post #1 of 4
Thread Starter 
I have this memory in my computer: http://www.corsair.com/memory/intel-memory-upgrades/core-i3-dual-channel-kits/cmx4gx3m2a1600c7.html

I am overclocking my CPU, CPU/NB at the moment and ram frecuency was also raised by 60MHz (1600MHz > 1660MHz).

I decided to put 0.015V (1.650V > 1.665V) to make it stable with the increase. But after three hours of prime i got rounded error.

After this i raised my CPU/NB voltage by one step and changed my memory command rate from 1T to 2T. Now prime testing this with no errors after 4 hours.

Now Im just thinking that if my ram even needs added voltage with that slower command rate.

Ram is rated 1.65V and I raised the voltage by 0.015V. What kind of disadvantages will this cause? Will this degrade my RAM:s lifespawn? How much? Other disadvantages?

I have two options:

1.) Stop my prime test that has been running for 4 hours and start the test again without adding RAM voltage.

2.) Keep runnig the test that is running. 0.015V increase in RAM voltage wont hurt RAM at all.

The change from 1T to 2T is probably enough on its own. Experiment a little and see what works best. That tiny bump in voltage is very unlikely to harm anything, you usually have around a 5% 'safe' window for adjustment. That being said I wouldn't run it un-necessarily if I found I didn't have to. Memory tuning is all about experimenting and seeing what works, what doesn't and what doesn't even make any noticeable difference at all.

bump up your nb voltage..see if that helps..60 mhz increase on ram isn't a whole lot..1-2 notches over stock should cover that

I tryied it with the voltage that memory is rated 1.65V and with lower command rate slower 1T > 2T.

Prime the application itself has crashed two times now. It says Prime stopped working.

First time it happened almost immideitly and second time after six hours.

What does this usually mean?

RAM instabilty?
CPU instabilty?
CPU/NB instability?
Software problem?

Do you mean NB voltage no CPU/NB voltage?
Is northbridge on motherboard?
Does it help stabilising RAM?

I think im going to add 0.015V to RAM voltage and try prime testing it again. Or should I do something else?
