Sounds like you just killed your self and your co-workers.

Could it be possible to adjust the timeout of the idle miner notification? Currently I get more than a handful of spam a day. And I mean spam as the worker is always working fine when I go to check on it, not even return or get work failures have ocurred. The vardif apparently works quite aggressively for my 3x5870 rig. Some times it spews out shares like mad and then again it hits the timeout between shares.

Otherways just smooth sailing !

Im mining with poolerino.com!
I'm getting pretty amazing response times too!

Mmmm serrrrrvers

sounds almost like your cards are in ULPS because the 300mhz is the idling clock speed(crossfire bridge connected? crossfire enabled from catalyst?). Have you tried manually setting the clocks with trixx? Have you re-installed the drivers? My windows never survives a card swap or slot change etc. Drivers needed to be re-installed every time I changed something.

I'd advice to always connect gpus in parallel! In series the last cards doesn't get enough cooling and the restriction of the loop is huge! Just make sure your blocks are the same make. i.e. mixing 5870s with 5970s in parallel(if you could do it) would be really bad for the ones with more restriction.

I sure am interested. However what keeps you from just scamming my hard earned btc/usd?
I could pull the trigger for one of those 3770s right now, if I'd know I'd actually get it.

If you think about this water boiler business real hard you'll come to the conclusion that this second boiler is just stupid over  the multiple heat exchanger idea. This doesn't save any power over the plate exchanger it just takes a huge amount of space.

In theory this would allow for greater delta T because it has longer time to build up the heat. Adding enough plate exchangers would do roughly the same however.

In your case when there was nothing connected to the motherboard wouldn't it have been easier to just tighten the links outside of the rig -> attach all the cards together -> place the whole stack on the mobo ?

So I guess this was with the Swifttech links. Were they hard to press together vs phobya links?

DT: how many cards did you manage to convert during the weekend ?

I agree with DT. Those Swiftechs are solid. The smallest clearance model sports 11mm spacing between mount points.

I have those Phobya connectors, but I don't see an issue with them unless you pull them too far apart. One failure point more though.
I think DT's setup has more pressure than average Joe's so he'd be better off with the sturdiest he can find. That silicone sealant wouldn't be bad idea either.  

Oh and that koolance thingy is rubbish. The price is ridiculous and it doesn't have even nearly enough cooling power for rjk's needs.

I actually have a nice sandwich going on with two 5870s(ek fcs5870v2)  I removed the mounting plates to get them as close together as possible. As you know 5870s have those stacked DVI connectors so they always take two slots but with even 5970s you can't really get them much closer to each other without having a really slim block(xspc) and some exotic sli/crossfire interconnects(Swiftech).

There hasn't been any problems yet. I do have zip ties to secure them together.

There's only so much I can do. My PSU is the Be Quiet! e9 700w which is internally similar to FSP Aurum series(the PSU is also manufactured by FSP). 5970s are on the pcie power cables and my 5870 is on the CPU 8 pin. the last 5870 is powered by another PSU. Just starting cgminer so that both cores of the 5970 start will trip the OCP on my PSU. The mobo is also powered by the e9 however the CPU power comes from the other PSU.
This is a bit funny way to do things I guess but the 5970s were picky about power not going up simultaneously on the mobo power and the 6pin.

As far as I can tell I shouldn't be overloading any of the rails. It could be that some PSUs aren't so good with high transient loads.

If your power adapters do have two 4pin molex connector to one 6pin connector then that is a lot better. However does your PSU have 4 cable harnesses with those 4 pin molex connectors? Because if you don't take the power from different lines it is no better

Did you down clock the ram while mining? It saves a few watts.
My PSU has this dreaded OCP and if I don't start my cards one by one it trips every time. It even trips if, while mining, my CPU goes under heavy load for some time. According to kill-a-watt I should still have over 100w of headroom but these processing spikes can draw a lot of current when they occur. So while PSUs should be able to produce the power they are rated for YMMV.

What's the make and model of your current PSU?

ouch that price is way higher on the top end models than the MSRP
that paperclip $260 price seems nice though.

1: Yes it should be. At least my AMD 2x5970 + 2x 5870 setup works ok. 11.12 catalyst is needed though. the new drivers work if I go to safe mode and disable one of the 5870s. So if you want to avoid driver swaps every time you do gaming then you should either dual boot or just use BAMT for mining.

2: You don't need adapters, just turn the secondary PSU on before starting your PC(primary PSU). You need to ground the green wire on the 24pin mobo connector of the secondary PSU to turn it on. I actually have a relay that does this for me when I start my PC. However some GPUs can be picky about the 6pin PCIe power not going up simultaneously with the power from mobo(that's why you might need to start the secondary PSU first).
There has been a lot of talk about this on this forum, and the consensus is that it is safe while it may not be practical at times.

3: If you can spare it buy the Antec it probably has much greater efficiency than your current one so it will eventually pay itself back. I do not recommend using those 4pin molex to 6pin PCIe power adapters as you are pulling the amount of current through 2 wires that you normally pull through 6. While it will work it is not good for the graphics card in the long run. The power components are starved of current and need to work harder. So either buy some weird splitters or make your own.

I made my own and use a spare 8pin CPU connector cable to power my gpu.

Did you get the new backplane yet?

I think that would make the rigs a nightmare to maintain. Besides as it isn't the purpose to do extreme cooling here simple temp controlled fan killswitch would do. And a mag valve would do for the tap water cooler dude.

Okay, now that was good to know! This could easily happen to DT as well if you put your rad outside.. Although 24 GPUs would draw about 1060w while idle so there would still be a good amount of heat going in to the loop but if the fan blowing through the the rad keeps running full bore after the net is out temps would still drop rapidly and low.
A kill switch shouldn't be too difficult to do.

Ek blocks are half plastic but condensation would still happen on the steel plate some of the blocks have on top(5870V2 & 7970). Some condensation would also happen on the sides. I think the under side facing the card is getting some heat  and the air doesn't move there as much so it is probably ok.
