folding for a longer amount of time at the same cost is worth more in the long run.

True, I've noticed that the higher the OC goes, the more bumps in Vcore it takes to go to the next level.

This is highly subjective of course, but what is the highest Vcore that you would be comfortable folding at 24/7? Gaming is a bit different, because you may only game 3 hours a day or something.

Don't forget, higher frequencies make the CPU draw more current.

Power = Current x Voltage since: J/s = C/s x J/C

But, Voltage = Current x Resistance; current and voltage both cause an increase in heat so if voltage gets high, the current also increases because the resistance has to stay constant.

Tl;DR mucho heat and pwah at high clock speeds and voltages

I had to read this several times to understand your meaning. Ultimately, if heat is kept in check and the voltage is not "too high," then I am probably ok. I think. I am actually kind of a wimp about increasing Vcore any more, but realistically I still have room to go.

This is OCN, I should have known most people would say just go for it! I am very happy with where I am at now, but in the interest of competitiveness I am gonna go for 5.2. If I want to climb the ranks I have to go faster!!! lol.

You can only fold -bigadv which is where you are going to see the 50K+ppd on either native linux or in a VM. I have never been able to have a VM give up cycles as easily as the windows FAH client does. While your rig would be awesome for -bigadv if you are using it frequently it would not be such an attractive option

Ohhhh, I understand. From my understanding, it is questionable whether the 2500k will even continue to be able to fold -bigadv, based on the new deadlines imposed. I'm not really interested in putting more money into my rig. I only have 4gb of memory which is not enough to run VM anyway. If I upgrade my CPU or GPU, my PSU will no longer suffice, as it is only 380W. So I am sticking with my current equipment and will simply max out the MHz..

If it is a dedicated rig with your OC it is possible to run the bigadv no problem. I have seen people on this forum hit the 60k mark. But with the rest of your specs (mainly ram) it does not look like you would be able to run bigadv unless you did it in native linux.

My main reason for saying no to the OC was just the instability issue. You already have a very good OC on the CPU and you are going to be fighting every mhz. With the risk of losing WU due to instability It may take a while for the higher clock to actually pay off once it is stable. Folding is basically running a 24/7 benchmark on the machine so even a small problem will eventually cause the loss of a WU.

Ok, so I'm now at 5200 MHz and 1.4 V and very stable. I am comfortable at this clock and temps are cooperating. Maybe sometime when I get the guts I'll go for 5300 MHz. I've almost broken the team folding rank of "2000."

Right now my equipment can't run bigadv, but I'm perfectly fine with only SMP. This is fun!
