Dual Channel vs Single Channel folding speed

post #1 of 11
Thread Starter 
Through a number of compounding errors, I had my ram in two adjacent slots. This morning I was reading a post and someone said that the OP should move their two sticks of ram to the same colored slots. I looked at my rig and what-do-you-know, I've got my two sticks in the wrong slots! I think what happened was I was in a rush when I built the first rig with a ASRock board and even when I took my time, I put the ram in the same slots. I do feel a bit foolish.

I did the change before I got ready for work, so I'll have some better numbers tonight. On a 6901 wu, my 2500K went from a tfp of ~29:30 to ~26:50

There wasn't enough time for me to see how much of a change there is for my 2600K on a 6903, but I'll find out tonight.

i know someone who once misplaced a GPU, so no problems there mate
your number on the 2600K will increase a bit ->lower TPF

I don't know if others have confirmed this but way back when (2010) I was running -bigadv on my P6X58D-Preminum board I did see TPF reduction (by about 90 seconds) if I configured so as I was in tripple channel. All I had to do was put a 1 gig stick (total of 3gb) and I saw some benifit.

PPD numbers on the 2600K will increase, as the TPF will be quite lower, and given that it is a 6903, i suspect it will translate in something around 7-8K higher

Here are the changes:

2600K @ 4.8 w/2133 ram and a 6903 wu, ftp went from 54:30 to 47:50

2600K @ 4.6 w/1600 ram and a 6903 wu, ftp went from 61:23 to 60:10

2500k @ 4.8 w/2133 ram and a 6901 wu, ftp went from 29:20 to 26:50

I wish the pump I retired wasn't so noisy, because the Vem-X on my slower 2600K doesn't keep it a cool as I'd like. I've never oc'ed ram before, but it looks like I should give that a try on the 1600's.

Nice TPF reductions there

If you can increase the speed on those 1600MHz ones, up to 1866 or 2133 (not very reallistic, or at least a bit hard to get), even with very loose timings, you could reduce the TPF by a fair bit

This might help you out:

Yep, nice reduction in TPF indeed. If the 1600s are low voltage (like 1.35V) they usually work better for OCing.
