does northbridge affect PPD much??

has any x4 or x6 owners tried 2000mhz nb vs 2600-2800mhz? is there a big boost ?

Don't bump your thread that much. You're permitted one every 24 hours.

We might let it slide if there've been a few hours between posts, but 3 posts within half an hour is completely unnecessary.

[email protected] isn't really bandwidth heavy, the only real increase I could see the NB speeds doing is when they sync all threads as the NB also speeds up inter-core communication.

It makes a small difference yes, Increaeing your NB Freq will help with OC stability as well

I see, at most, a 100-300 ppd increase when going from 2000 to 2400 NB. Most likely the NB isn't even making that difference, but rather the starting and stopping of the WU giving different readings in HFM.net.

What on earth? lol! No! Overclocking NB help with CPU OC Stability, OC NB will improve system performance,

Overclocking the HT will decrease stability.

Take it to the AMD Forum's if you have a problem with it, I'm not going to start flameing

increasing the NB Freq is more for reducing latency, and increasing the throughput of the OS itself since it's increasing the speed of the RAM. So you won't see a major increase from it at all

Explain how...
Overclocking the NB helps to stabilize your CPU OC. For example, if you have your CPU at 4.0ghz and your NB at 2000mhz it will most likely be unstable, but if you bump your NB up to ~2800mhz it should stabilize you CPU OC (given that all voltages/ temps are where they should be). I'm not sure exactly why this is the case, I just know that it is.

He's right, a NB OC helps with stability, but a HT OC can actually decrease stability/ performance. The HT should be kept as close to 2000mhz as possible, I think some tests have shown that performance can start to decrease if it's pushed over 2200mhz.

I run my amd 1090T and be 940 with the nb around 2.6,ht around 2.0,
the thuban is at 3.7-3.8 (change it from time to time) and the deneb is 3.5.

can´t say I have seen any clear difference for folding at home with other settings= lower nb,but the system "feels snappier",very subjective opinion though.
