Low PPD 2600k

post #1 of 5
Thread Starter 
Ok well I asked this in the lounge but I then read my sig and relized why no one answered my question.

I have a 2600k @ 4.84ghz and it's only producing 26-27k ppd on a bigadv. I think I know the problem but I would like some input from fellow folders. The ram that's in there is a 2gb stick of cheapo OCZ ddr3 ram. it's running in single channel @ 1033mhz. Could this be the source of my bottle neck. The reason I ask instead of going out and picking up a new kit is I have to wait till Friday which is after the CC starts and if I can maybe find out it's something else it can gain some points for us

Edit-- The WU is a 6900 and the TPF is 36:15

Also, I'm out of coffee. If anyone feels like donating some let me know

You need 2 sticks to run dual channel. That is the most probable cause of the problem. We saw that problem with another member not to long ago.

Agreed. Up till 1500ish ram speed has an effect on my PPD and I'm running triple channel. I would presume that single channel would severely limit PPD since bigadv uses a fair chunk of memory.

I'm out of coffee too...

Maybe post a screenie showing cpu usage? And yes I believe BIGADV is more sensitive to memory bandwidth then regular SMP.

For sure it is the ram. My 2600k was performing horribly in single channel. Went to dual channel, and BAM! ( ) ~6-7 tpf improvement in bigadv.
