I promise you i'm not. Also just for clarity's sake: a gain of 20 points in 3dmark is not the "most performance gain". Its effectively identical to the lower clock.
What this means is you achieve virtually the same performance, for a lower clock. Less instability, less issues. If you try these things out I promise you'll see what I"m talking about. Leave core at the same speed, and check it going up from 1250 in increments of 10. At around 1270-1280 you'll see a large drop, and then by 1350 it will be back to pre-drop level.
Once again if this is the case for you, why bother with the higher memory clocks? Again another member (Roadkill95) and myself have both independently verified this. in addition to the original member who informed me of this. If your card doesn't do that thats cool, but I am 99% sure it does, and quite frankly I wont believe you until you show me benchmarks of all those speeds.~1250 will be the same as high numbers is my point. Maybe a 20 point difference at WORST. We should all know 20 points in 3dMark aint crap. You could run identical settings twice and get a difference of 20 points.
I also say around 1250 because mines like 1255 and roadkills was around 1260.
I also doubt very much that coincidentally 3 of us achieved the same results on 7850s....As far as I know it shouldn't be different across different chips, because it has to do with memory error checking on all 7850s.
Look just try it out krabs
. drop your clocks down to around 1250 and see how big of a difference it makes in 3DMark.
Now heres the kicker though: after a certain point, the increased speed OFFSETS the loss
due to the checks. While you may therefore get better performance, it will at best be minimal, unless you are like krabs and can maintain an INSANELY HIGH MEMORY CLOCK. But the gains if any are once again minimal. How many points for a memory increase that big?
Is it worth it?
I invite you all to check this out yourselves on your 7850 so me and roadkill can either be proven right or wrong.Edited by kmac20 - 1/3/13 at 3:38pm
