On the RAC question.... It might be pertinent to ask the members here how long it takes for RAC to settle on a new machine and new project.... and whether the trend is for an increase or decrease in points using this current points award system.

Historically faster machines were favoured when working with a wingman. I believe that still to be true, but others might confirm.

That the current points system is broken is proven so it really is pointless.

Undervolting is a worthwhile skill to learn. Personally I found a slight loss in performance even at the same speed.

Since BOINC 'Credit New' was supposed to give double credit and then 2 credits became a cobblestone with 100,000 being 1 TeraFLOPS, WCG would have done proper by also doubling it's points or reducing the divisor from 7 to 3.5 to maintain parity with other projects. They did not. Effectively the WCG TeraFLOPS nearly halved on the 3rd party statistics sites when Credit New was implemented.

Gibbcorp, a bunch of these sticks could be an energy efficient solution if they come with the same type of processor as Z37xx. One could be connected to a display's HDMI and the rest to a USB hub, and then run via Windows Remote Desktop (needs Windows Pro) or perhaps Teamviewer (free). They should be cheaper than tablets since they don't have batteries and displays. But then again, tablets are part of Intel's contra revenue program and this stick is probably not.

OT

I feel I just have to link to this two year old article in NYT, on how owners of social media sites and cloud storage sites are wasting 90% of the energy. They don't worry about the electricity bill or the environment. I'm shocked.

Wolfin2000, I have a dual processor workstation and there's no room for large heat sinks. The HP Z600 also has a stupid design, having CPU1 blowing hot air into CPU0's heat sink. As a consequence CPU0's temperature is 9C higher than CPU1's. A really stupid design philosophy that HP and DELL take turns on implementing. Whoever is originally responsible for this design deserves three firm face slaps. On the same cheek, so that it hurts longer. Then next time the designer will hopefully work with convection. For instance, having the CPU fans bowing air straight up, instead of into the rear of the case.

I really want to keep the max temperature under 60C, and that means I'm limited by CPU0's temperature. So I'm going to try to even out the temperature differences between the two processors, by installing a more efficient fan only on the CPU0's heat sink. One that's 25mm deep, instead of the current 15mm deep fan. Problem is that one corner of the fan is blocked by a pin on the motherboard. So I found Noiseblocker Multiframe M8-P, which has individually removable corners. It's silent and has high airflow. I don't know what air pressure it has, but should be higher since it's 10mm deeper.


I like the cooling principal behind Hyper 212 EVO. Having the copper pipes in direct contact with the CPU lid is efficient, provided they have an even surface against the CPU. But I think Cooler Master V4 GTS is even better, because it has a horizontal vacuum chamber. Here is my previous comment on this matter.

KliK, I just tried that and both processors' temperatures went up 2-3C with the case closed. When I left the case open, the temperatures reversed: CPU1 had 3-4C higher temperature than CPU0, which is almost opposite to the previous state.

So this obviously didn't work. Maybe I'll have to rethink the decision to buy a better fan for the CPU0 only. It seems they interact, so maybe it'll be best to replace both.

I'm beginning to think that perhaps I should've bought used components and then assembled them onto an enthusiast motherboard, instead of buying a used workstation. Then there would have been enough room for a large heat sink, instead of the medium sized I have now. It's also possible to undervolt such boards, and mutated server boards, such as workstation boards, don't have any undervolting options in the BIOS. Undervolting allows the processor to run cooler while maintaining performance, which is a win-win setup.
