How much more ppd will i get, in ubuntu if i use 2133mhz ram instead of 1866mhz ram? Are we talking like 5kppd, or something that wont matter? Also, if anyone knows how much more i will get at 5ghz instead of 4.8ghz, let me know also.

Well...

The only way to know for sure is to try... these are free changes..

Try them out and let us know

Also - if the ram won't push 2133, pull 2 of the sticks out for 8gb total...

yea, i but i kinda need the 16gb for video stuff and other things

I got this 16gb on newegg, but for $50 more i can get ram that is 1866mhz default 16gb, and oc it to 2133mhz, so if its gonna make a big difference, i will pay the extra $50.

well, i changed it, and its actually the same, maybe it does not take effect right away or what? Maybe its just me? lol i would of thought it would of effected it.

I can't give you any solid numbers for the difference between 1866 and 2133... but it's probably not huge, and if you can OC the 2600k a bit more that might be a better option.

see, its default, but i can get it 1866mhz, not 2133mhz, so i dropped it to 1600mhz, to see if there wa a difference, none so far. And i want my 2600k 5ghz, but i cant get it without like 1.5 or 1.52v, and then my temps are like 85C, and its 70f ambients lol so kinda to hot for me.

After you changed the memory speed, how long did you wait to see if there was a change? PPD changes can take 3% of a work unit or more to become noticeable.

What timings were you running at 1866Mhz 10-10-10-23 -1T I am guessing by looking at your sig, that is pretty high timings for 1866Mhz. I run my ripjaws DDR3 2000Mhz@ 1.55v at 2100Mhz 9-11-9-29-1-T, 1.62v. It really does no good to have faster speeds if you are having to run slower timings you will not gain anything. The only 1800Mhz ram I own runs at 7-8-7-21-1T, 1.65v

a 3minute TPF drop on a 6903 would equate to roughly 6k ppd
