Please consider our pool for your talkcoin needs talkcoin is in our other tab.
Check out our great mining pool at https://www.minep.it/

Already mining with you guys! Awesome pool Tongue

There used to be a day I was on the top 10 talkcoin miners, but now, even with this boost, I'm nowhere to be seen (well, probably #11 xD )
Could you consider lowering the payout treshold to 50? TAC is getting really hard to get by as a miner, so 100 was fine a week or two ago, but times are changing rapidly Tongue

How can I mine same time on CPU and GPUs?

I'd suggest you run the CPU mining with -t 3, to use just 3 cores, leaving one free for GPU miner duties (relevant if that CPU coin miner is already optimized for AES-NI). In any case, you can play with the number of threads for CPU mining all the way up to 7, just not the default (which uses all 8 threads).

I usually go into the task manager details and set the affinity of the GPU miner to be on my 1st core/thread (or the 1st two), and set the affinity of the CPU miner to the other ones, thus isolating one from the other.

This makes me think that ccminer just has difficulties with cross-threading on the cpu. If work A is on core 0 and work B is on core 1, but you're also CPU-mining on those cores, ccminer will have to pause a bit, and he doesn't like that Tongue

Also, Intel knows how to deal with threads, so this might be why a Celeron is a winner for ccminer.
So yeah, try setting affinity to lock the processes on cores.
Please report back if that did or didn't do it Cheesy

If it did it, it's something I will implement in my ccminer gui. Should you set the affinity per ccminer, like ccminer30 on core0, ccminer50 on core1, etc... or does it matter at all? I see no real difference when I put them in one thread on my system (i5-3470)
But before you ask, I won't do a gui for minerd Tongue

Thanks, this helped me!

I have 8 logical threads on CPU - I've set 4 to CPU miner and another 4 to GPU miners - works fine

However, when I tried to assign only 2 logical threads to GPUs then I was loosing hashrates, 10% drop. I think it might be related to fact that I have 2 GPU cards, hence 1 physical core per 1 GPU card (i7-4770k has 4 physical cores and 8 logical)

Good to hear! I'll be including this one as an option for my GUI.
