Corsair Vengeance PC Memory 8GB 1600MHz 2x4GB VS G Skill ripjaws 2x4g 1333MHz - Page 2

Personally, I'd go for the higher rated kit as a preference.

I know as long as the sticks will run at 1333, either will "Do" but that's just me and what I'd prefer - I've had good luck using that way of picking sets to buy so far.

Redwoods is correct, if the voltage specs are similar yet one has a higher rating the higher rated set wins. Do bear in mind though the IC's of the sticks will be a factor and voltage needed is an indicator but not an absolute whether it's a decent to good set of IC's in the sticks but as it is with CPU's, nothing is guaranteed related to how far up they could actually go or how tight you could set your timings and still have stability at a given MHz when OC'ed.

The CPU's own IMC and the board itself are factors as well and I know that from my own personal experience and results. Also know that some of the higher voltage sets will fly too, again the RAM's IC's will be the biggest thing that determines if it's a good set or not but nowadays the lower voltage kits tend to be either equal or better with obvious improvements taking place over time.

However the biggest factor of all is the price..... And the OP did state a set amount of money he has/wants to spend.

Voltage is only one aspect of RAM OCing. There is simply no means to know how the different RAM kits will OC without actually testing them. Even though your point about RAM voltages has merit it's not a guarantee of how the RAM will overclock. Without testing everything is speculation. No one knows how the RAM is built, what IC's were used, how the RAM frequency rating was decided, or how the RAM will perform OC'd. That is why you test to eliminate the guesswork.

It's far more fruitful to run objective, scientific RAM testing instead of posting subjective opinions that can be completely meritless and based on false assumptions.


Kryton-

Yes you're comments are right on the money. No guarantees just potential indicators and MANY variables which makes it impossible to predict outcome. That is why we test instead of guessing. In the engineering and scientific communities history has shown that one accurate test is worth more than 1,000 meritless opinions. thumb.gif

I never said it was the whole aspect. While it's true you never know for sure what you are going to get, if a particular run of kits gets tested enough,people post their results and soon a picture is painted of it's general capabilities. That's where OCN comes in and give advice based on the online results. thumb.gif

I didn't say that you said the voltage was the whole aspect. What you, I and Kryton have pointed out is that there are numerous variables and indicators but these don't tell you exactly how the RAM will OC. With eight IC suppliers RAM models can have different ICs from day-to-day or week-to-week. A general profile may or may not develop.

Everyone has an opinion but that doesn't tell you if a specific 1333 MHz. RAM kit is able to OC more or less than a specific 1600 MHz. RAM kit. No one can look at two RAM kits and tell how high they will OC without actually testing them, which is precisely why we do test them instead of guessing. As Kryton pointed out the IMC and mobo also influence the OC results so it's simply impossible to know without testing.

It' smart to test not guess nor make meritless assumptions and conclusions that can be misleading and a disservice. wink.gif
