What does EVP mean?

Hi,

As per a recent thread, I've recently upgraded to 4gb OCZ RAM using 4 x 1GB sticks.

I've had a few lock outs since moving from 2gb to 4gb and now noticed that I had my memory voltage set to auto in the P5n-e BIOS.

I've upped it to 2.0 somthing and still got a lock out. Now going for 2.1 something or other and going to see how it goes.

I noticed that the spec of the memory says 1.9 - 2.0 volts as the recommended, but it says EVP 2.2.

Does that mean I should set it to 2.2?

Thanks.
 
Is it dangerous to go that high?
Or even should I need to in order to run the memory at stock speeds. Maybe I need to increase it because of the 4 sticks though?
 
you will only need the EVP when overclocking, it isnt too dangerously high as the sticks are designed to handle that voltage
 
If the memory you have is 2 x these - http://www.overclockers.co.uk/showproduct.php?prodid=MY-072-OC&groupid=701&catid=8&subcat=813 then they are good at 2.1v, I recently went from 1 kit to 2 kits and had to increase the voltage to 2.1 before they would play happily, I also got confirmation from OCUK and OCZ that they should be run at 2.1v. It seems the spec on OCUK is wrong when it says 1.9-2.0, as its actually 1.8-2.1 with EVP to 2.2v. Oddly OCUK spec if you look at this memory in the list view - http://www.overclockers.co.uk/productlist.php?groupid=701&catid=8&sortby=nameAsc&subid=813&mfrid=12 shows correctly as 1.8-2.1 confusing :confused:


You might also need to up the Northbridge voltage as 4 sticks puts more pressure on this, but only do that if your still having problems at 2.1v

Sure is, which is a pain if that's what your board defaults to after clearing the CMOS, I couldn't even boot with 1 specific stick at 1.8v.
