memory OC = Less performance

[danstark1243]

in the process of overclocking my r7 260x at a core clock of 1150 and memory clock of 1250 i would get a score of 683 in unigine heaven but when i overclocked the memory to 1300 i would only get 668 this makes no sense to me. has any one else experienced this and is it a bottle neck somewhere else in the system?

Did you at least do a FEW runs to see if it was a ONCE off.?

i ran it 5 times each way and the numbers were only 1-3 off the others of the same set up

could be VRAM throttling or something
