Whats more important for more PPD, speed or low latency?

Speed at at decent latency will always beat slower memory with faster latency.

Ram does not really change PPD that much. It may only be a minimal gain, but I would suspect speed would be best.

I seen Koven do 2k PPD more than me @ the same speed with just different memory. So there is something to this.

Disable pagefile.sys, you don't need it. (if you have not already done so) My PPD went up over 1k *shrug* after I quit using it. I used to have it on my 1TB, but if you are running an SSD and have the memory to spare (8Gb is enough to spare) you easily have enough memory to run without a pagefile.sys

fwiw

So many variables that make him get 2k more than you.

GPUs folding?
PC usage?
Processes running?
Ram timing/speed?
Work unit?

All that combined makes a difference.

no GPUs, same processor, same speed, diferent ram speed.
I guess no one knows for sure.

It does make a difference, but it isn't ground breaking.
Why not ask him for his ram speed/timings and try it yourself and see if you get 2k more?

Since you are using Sandy Bridge this should apply to you, or at least give you a better idea about which settings have which impacts (or enhancements) to performance of memory.

i think speed has a bigger impact on intel rigs, AMD is more about timings

i did notice a decent boost after switching to 2133 from 1600
