Why mining the MemoryCoin 2.0 (MMC) would reduce my speed of GPU coins?

I think the MemoryCoin is one kind of CPU coin, it has no relationship with my graphics cards, but when I launched the mining of MMC, my hashrates of graphics cards will be slow down, is there anybody same?

how much ram do you have?  overall system usage has a direct relationship with running other programs

It does take some CPU power to run CGminer and your graphics cards. If you're using all your cpu power to mine, you will lose graphics processing power due to the lower cpu efficiency.

4GB ram.

It says 1GB, but I dont understand it means totally 1GB or each thread 1GB.

But mining other CPU coins like QRK do not reduce my hashrates of GPU coins.

I saw that too. When I mined MemoryCoin, my GPU HR reduced to 1600 KH/s from 25 KH//s. That's why I stopped mining this coin

Always leave 1 core for cgminer/reaper/guiminer etc. You need some free processor resources for the non-scrypt execution of these applications to work most effectively. If you have an 8 core system, try running between 4-7 threads and see what kind of results you can get with those settings.

Yes, Leaving one core to "feed" your gpu does the trick for sure, but if you want to max it, reduce cpuminer (memorycoin-qt) priority to low and set gpuminer priority normal, maybe to high. Doing so I've gotten the best out of my hw with memcoin+F@H combo

I have this same issue with my ASICs, even when I turn Memorycoin down to using only 1 process out of the 4 I have available.  Considering I have 16gb of memory, it is hardly a memory issue either.  It completely zombies my ASICs, but there's no help being given in the MemoryCoin thread.  Unfortunately glad that someone else has the same issue.
