Indeed, I turned on a couple machines and now my basement is nice and toasty. Some friends said that they started using their furnace and I'm wearing shorts :)

Somehow I've gotten the 7.xx client to load without giving me a systray icon.I can only get 'web-control'......I'm sure it's a flag , but dammed if I can find it....

A 4P socket F (2.7GHz Opterons 8384) platform was doing 28k PPD in Windows while the 7850 I have, clocked at 1 GHz is doing 39k PPD.

Those opterons need some linux, start up a cm in windows and run it that way if you need windows and can't have it running native. Thatl up the points quite a bit. They should be bigadv capable?

Based from extrapolation with 8389 they should finish 8101 in time, but I gave up. Even considering PPD/watt I am still better with Radeon 7000 series. In fact I removed 2 CPUs in order to have a working win7 install. As soon as I will have my Sabertooth setup working, this setup will be powered down. Opteron 8384 is a cpu that consumes 115W at full speed under folding which is about the same amount consumed by a 7850. I intend getting another 7850 and powering down the quad mobo. 2 x 7850 will give me the same PPD as a quad cpu rig at 50% the electricity cost.

Honestly, the writing was on the wall nearly a year ago when we first heard about QRB for GPU's. I'm surprised it took this long for people to start realizing that GPU folding is where it was currently at.

But, never fear, Stanford will soon realise that the 4P guys are feeling neglected and will increase the QRB's for them, too... (I jest, but seriously, you don't think Stanford will F-around some more?)

Yeah, thats one of the "fun" things about folding. The constant change, they do say at the start of it though that things are going to fluctuate, and that a lot of it is beta (the GPU QRB, bigbeta etc) They tend to change it up at least once a year as hardware and their priorities change.

Titans

I'd love to see what a Titan would do w/ watercooling and similar voltage. Assuming it could clock to the same as these GTX780s, the extra shaders should give a consider increase. A 15% decrease in TPF is a 50K + increase in PPD.
On a Titan that you once knew, running at the 1.28 volts at 1.267 ghz a 7811 unit consistently got a TPF of 0:54 which calculates to 219K PPD. I didn't try any higher yet. I haven't tried the LLC hack from Zawarudo or whatever his name is.

With just the one video card going and 25% CPU usage for the one GPU slot, the whole PC is using 368 watts of power.

With both it was in the 560 - 580 range I think. If both cards run at the same speed I could get 400+K PPD from two vid cards.

This is roughly the same as my twin dual Xeon boxes, but it's more consistent as long as Core 17 units are available. The twin Xeon boxes would be better with 8103 or 8104 units though.

Update: The second adapter is now on RR09SS BIOS as well and at 1.28 volts hitting 1240mhz and with a 7810 it's getting a TPF of about 1:13 which translates to 220,000+ PPD.

Holy.... What the flip.

So theoretically you could find the lowest power usage CPU for this, run these adapters and shave off another 40-50 watts, or NOT OC the CPU and get nearly 500K PPD with about a 500 watt power usage. 1000 PPD per watt is sorta the golden standard to me.

I've been using the Zawarudo LLC hack and it has worked great. The only issue is that I need to start it every time I reboot. The card has been rock solid stable @ 1.325V 1372/3200MHz for a week w/o a single errored out WU. Time to figure out what kind of impact such a 'high' voltage has on the card in the long term.

Without knowing the acceptable limits of the chip's accepting voltage, I can't say, but on the Titan thread there were some concerns about the VRMs, but these deaths were attributed to poor cooling and/or extreme voltage and hard mods.

I know at 1.325 both cards on Unigine Heaven are using a bucket load of power. 760 watts showing from the Kill-a-Watt. For this I was rewarded with an extra 50 mhz to about 1.32-1.35 Ghz folding stable, but only 1.33 or so Unigine Stable without artifacting.

The Zawarudo hack is great, but I think it would be something I'd only enable while benching, as well as the 1.3 volts. I'm going to explore the 1.2 - 1.3 volts range to see if there is a sweet spot for each card. This is harder when there are two installed though.
