Some differences in Precision:

Different UI (obviously)
NVAPI based Frame Rate Target
Pixel Clock Control
K-Boost
Different method of voltage control

Excellent reason to never use PrecisionX..... I guess it is acceptable on EVGA cards, since you guys seem to just replace everything :S.
I was not aware of the Min/Max being shown, it just said in the thread that it does not have that particular feature. Guess i should do some more reading... I wasn't aware you had in-house developers for your overclocking software :S thought this would lead to an administrative hell, but what do i know?...

That being said, i am a huge fan of EVGA, by far my prefered card manufacturer. Sadly the MSI PE was just to amazing not to get (especially considering it was 15% off at the time)

That makes no sense unless you card somehow has memory voltage control you can edit in bios and you increased that.

Increasing core voltage will do nothing to make memory more stable

It does indeed make very little sense. But... It is often the case, that you may sacrifice some memory overclock, if you go all-out on your core. Allowing more headroom on the core *might* have made him more stable on his core.

That being said, 259mhz more on the memory from a core overvolt is... well... not realistic.

Most likely you crashed in Step 1 when you first combined both maximums. This is quite normal. From here you usually have three paths that you can take. Either you sacrifice some core frequency in-order to maintain your maximum memory frequency, you sacrifice some memory frequency to maintain your maximum core frequency, or you sacrifice a little of both. Neither option is better than another on the whole, it really depends on your specific GPU and how much you have to give up of one to maintain the other. Some GPU's barely have to give up any of one to maintain the other. Also, some applications benefit more from memory than core and vice versa. Generally speaking though, 1MHz on the core is worth about 4MHz on the memory in terms of performance, keep that ratio in mind as you reduce things.

I don't understand what you're talking about, sorry...can you be more specific?

When memory reaches a speed of which it becomes unstable, miscalculations will be done. These calculations have to be corrected. These corrections will cause slowdowns.

I never saw this phenomen and I had a lot of different cards from both red and green camp smile.gif

Usually core stability and memory stability are not related to each other...I am always getting same results when I try to overclock just one or both.

For example if cards crashes at 1200 its gonna crash at 1200 no metter what memory clock is.

Only thing which does metter when it comes to kepler card is of course power limit, if you gonna OC both memory and core you have to increase the power more.

In any case, like you said, its not going to make 259mhz difference.

Nothing has really changed, his memory is probably still unstable, he is just not aware of it smile.gif

I think a lot of people dont test their overclocks properly, lets take my card for example :

Perfectly stable overclock is only +13Mhz core and +100 memory.

Far Cry 3 stable overclock is +25 Mhz core and +250 memory.

If I am playing Far Cry for only an hour or so, I can do +25 Mhz core and +300 memory

I can play rest of the games I tested at +50 core and +350 memory

I am sure most people here would choose last option, and run their cards at +50 core and +350 memory when in reality their card can only do +13 core and +100 memory

And then blame Ubisoft or Nvidia for "Far Cry 3 crashing problems" biggrin.gif

Then what I must do to make it more benefit for me? I believe I can reach 8 Ghz on memory though, as I can reach 7.4 Ghz without increase the memory voltage.

You cant seem to understand what is going on. Increasing the frequency even more will make it even slower.
You need to stick to 7Ghz, thats the best you can get from your memory

Basically what you guessed yourself is correct. Increasing it too far will reduce perfomance ( FPS )

But you can just disable K-boost?
