Guys there is an easy solution to all the crap. Buy a decent power supply! If your throwing over $1000 on 6 cards, why not spend $200 on a decent fully modular psu that you can connect like 9 molex strands to? My corsair rm power supply has enough sockets that i could connect atleast 9 entire molex strand, not plugs, entire strands. Thats more then enough to do any rig. Dont skimp out on the psu! If your psu goes it will take your cards with it!
What one do you own/recommend?

my cards at the moment are on an old XFX 750W partly modular psu. it allows for 6 individual molex strands to be connected so i can run 4 gpus on their own run to the psu. my main pc has a Corsair RM1000, amazing quality psu, and has a 5 year warranty but it has a single 12v rail cable of running 900W so it can handle the GPU. running 6 cards, you need 300w for your cards, and i recon maybe 300w headroom for the rest of the system, allows for a power hungry rig. so the RM750 would be good power wise but it only has 4 peripheral ports. the 850 has 5, and the 1000 has 6. the 1000w also allows you to monitor the current being used by the system to figure out power usage, and is extrememly power efficient and the fan wouldnt even spin till it got to 400W load i havent had the psu long but it seems very good. with £155 so their expensive but their very good quality. its the first psu i have bought in around 3 or 4 years so its a huge improvement over my xfx rubbish which is noisey and driving me mad now. so i dont have a lot of experience with psu side but i know the RM psu's are recommended a lot. as a note, if you want to monitor the power usage, if you buy anything less then the 1000W, it doesnt come with the adapter needed so you have to buy it separately! but as i said, if your psu dies it could take the entire system with it, so spending an extra £60 for a higher power and higher quality one isnt always bad when losing a 6 card rig could cost a few thousand

The problem with the RM serie, is that if you have a fan at the bottom of the case, you will have to remove it to install the psu as it is a bit longer than standard psu...

Yes that is true so its something to check. I have a giant case so it didnt effect me too much. I think its about 30mm longer then my old psu

PSUs are most efficient at 50% load. If you go lower load or higher load than around 50% you will be incurring greater electric bill costs for no hashing gain. Or go for 80 Plus Platinum certified PSUs. The cost difference between 2% efficiency is not something to scoff about. Say your system pulls 900w. 2% less efficient PSU requires 18 extra watts from the wall. 18w * 24 hrs * 31 days = 13.392kwh. If you are in tier 4 electricity, at least in California Bay Area, that costs $0.36 per kwh. That amounts to $4.82 per month. That is a full day's worth of mining profits right there these days just on PSU inefficiencies.

Actually the corsair ones are very efficient even at lower loads. Switching from my xfx psu to my corsair, the power usage dropped by 20%
But i am in the uk so we use 240v so we get slightly higher efficiency because of the lower current

I plan to upgrade my psu to a 750w with better efficiency, but as of right now
I'm running 5* 750ti's (win7 x64, 4gb ram) off of a coolermaster 460 watt psu. Mining HVC with cards OC'd +130. The whole system pulls +/- 350 watts. 2 cards on powered risers (ribbon) supplied by 1 molex strand (connectors and wires stay @ 85f), 3 on the board until the rest of the risers show up.

I tested my rig , the 6 cardsone , with a 1100w coolermaster gold with all the extras and it failed too. So it is no use to buy that kind of psu. Just buy non powered non usb ribbons and you will be cool even with a 650w power supply. Christian One thing about the chrome boost. I saw on my clean installed system that chrome was not giving any boost to the hashrate , so i started installing thing - adobe flash , winrar , klite code and stauff. still no positive results of chrome . then i installed some benchmarks , 3dmark2011 and vantage and heaven bemchmark then i saw that i have the same score of hashrate 138-140 for one card , but when i close chrome it drops to 125-127. So chrome is bringing the system back to normal hashrates and obviosly some instalation of these benchmarks makes the mashine drop the hashrate.Witout intalling the benchmarks i was having normal hashrate and chrome had no effect . I hope this can help you figure out what is the problem.

Well that ended rather poorly.
Brand new $4k Alienware COOKED in less than one hour...lol
LITERALLY throwing purple? acrid smoke...my office still stinks almost a full 24hrs. later.
Don't think scrypt mining is for me!

Mining on a laptop can cause lots of issues like that because most laptops dont have the ability to take the heat away properly. My last gaming laptop did it, gpu fried the entire system

I never tried mining on my laptop, seeing as how running Torchlight I (albeit on the highest settings) turns it into a rather toasty lapwarmer.

About the Google Chrome trick: I am pretty sure it's the 1ms timer precision for multimedia applications that improves the hash rates. This is why Flash, Windows Media Player, had the same effect.
ccminer and cudaminer now ask the system for this higher timer precision, and hence Google Chrome is no longer needed to get the boost.

I get mine to sound like a jet engine mining scrypt (topping 95 deg C), but a properly designed laptop should neither fail nor crash nor smoke under peak load. Bad thermal design by Alienware. Covered by warranty I hope.
