I don't think it is fair to assume there will be a crash based on the same pattern Bitcoin had.  I think there is more things that need too be considered.  Not ruling it out as possible just not likely IMO.

I think it's fair now.

Bad analysis.

Litecoin does follow bitcoin pattern.

However, this is the 2ND SPIKE UP for Litecoin, not the first.   So it is like Bitcoin last April.

Back in April, Litecoin was trading below 50 cents and ran all the way up to $5.  Only to crash a few months ago to $1.6.

This spike is like when Bitcoin ran from $13 to $260.


How is it bad analysis? The description and link I provided about BTC going from $1-2 to +$30 is a lot closer in price to LTC's recent pattern of $2-3 to $48 than your 50 cent to $5. I never said that the recent LTC pattern is a bubble. I said that it's looking like BTC in 2011 which could make LTC a potential bubble. Just speculating that it could follow that pattern. Which at the time of this writing, no major crash occurred.

LTC potential bubble is looking like 2011 BTC bubble.

Let's look back at BTC chart back in the day. Looks like BTC was hovering around the $1-$2 range then skyrocketed all the way up to $30 something then back down to around $3.

LTC is looking quite similar.

I'm not familiar with the ASRock 970EX4 enough to say that it can run five GPUs. Check this out for motherboards that may work.

cryptokeeper...I was wondering if the ASRock 970EX4 and Intel Celeron G1610 Ivy Bridge Processor, would be able to run 5 GPU's on windows 8?

I was using your 6GPU setup from your site, but after reading your post and seeing as your only using 5 GPU's I figure I should opt to buy the cheaper mother board and just run 5 as well. Thanks

I am interested in a round BTC one, got any orange ones?

Please post a pic with something next to it for size reference.

Are these suitable for the rear window of a car on the outside?

Sorry I don't have orange ones at the moment. I had bought a bunch of them but have some extra left over.

Yes these are the exact sticker material that people put on their cars from the outside.

For your reference of size next to a quarter.

I tested each GPU individually and with others. Yes 1600W for five works. Six is pushing it. Read this post to get six working in Windows 8. MSI Twin Frozr 3 don't need to flash BOIS because it's voltage is unlocked.

When you tested each GPU, did you test them individually or with the others plugged in. Or one by one. I'll give that a try both ways in just a moment. So should I just count on only using x5 with a 1600w? If so thats fine for now.

Any ideas how I could find the 12.6 trick for windows 8? I had windows 8 with 13.1 earlier and device manger saw all 5 of them that were plugged in at the time just fine. However, when cgminer started I would see all the hash rates jump up where there suppose to be, but then the screen would either freeze or go blank and I would loose all control, it was like the driver was crashing.

Not having to short any pcie slots would be nice, I had to short one of the 1x on my gigabyte board. It has no problem though seeing all 6 in ubuntu or xubuntu, I just cant run cgminer with a thread concurrency above 1792 or all the cards but one report as off, on the flip side if i run at 1792 they all hash at 150 or so, but i get 10 HW error a second a card so thats issue as well.

I'd prefer to stick with windows 7/8 so that I can utilze afterburner to turn down the voltage, though I suppose a bios flash is always an option?

I figured out it was the rail from testing each GPU with it's closest rail. Then I found the GPU that didn't function in cgminer. So I tried it with a different rail and it started working. Hence I moved the power cable to another rail and got all five working. I could probably do six again by swapping out PSUs but the power consumption was going past the 1600W rating when I had six going. I had to underclock and turn intensity down to get it stable. If I were to do six again, I would use two 1000W PSUs.

To get six GPUs working, I used 13.1 on Windows 8 a 12.6 trick. I can't find the link at the moment but it's somewhere on this forum about six GPUs to work on a motherboard. Also no shorting PCIe slots on the MSI Z77 GD65.

I have the same PSU and Graphics cards as you and am struggling to get all six working. How did you figure out that one of your rails was malfunctioning? Also, did windows 8 see all six right off the bat? Just installed 13.1 and they worked?

I'm using an A4 FM2 processor with a gigabyte F2A85x-UP4 but so far its been nothing but a pain in the ass lol. If you have 6 msi r7950 twin frozr working good in windows 8 with that msi board, I might be making a return to amazon soon lol

I had the same problem as you. Mine was working with six GPUs. Then it went down to five. Then four.

When I had six running. One would go sick or dead. So I discovered one and removed it from the system. I moved around the PSU power cables to clean it up. Then another GPU would get sick or dead. I isolated that one too. Eventually the whole computer was locking. So I removed that GPU too. I moved these two GPUs to my office PC and ran cgminer. It ran like a champ for days while the mining rig was only running four. I then installed back one of the two by itself and it was fine. So I then proceeded to plug another in. It was crashing. I skipped it and went to the others. They were fine. I went back to the one causing the crash and tried it with another power cable. It worked fine. So I then added the other GPUs and moved off the bad powered rail. Now I got five GPUs working again. I don't think I can get six because of the bad rail. But now I know what the problem is.

I recommend you test each rail on your PSU or use another PSU.

TLDR: Bad rail on power supply cause sick/dead GPUs or lock ups. Moved the power to another rail and it works fine.

I had six cards working on the mining rig before. It was working fine. I tried 13.1, 13.3, and 13.4. All crashed.

I suspected it might be the motherboard as well but it can start the other GPUs just fine. So that's when I suspected it was the two GPUs until I put them in my office computer.



If you just put the two GPU (which is in office computer) into the mining rig, does it work? If it works, then add more GPU on the mining rig. I suspect something might be wrong with the mother board.

Can you try Catalyst 13.4?

Does it happen more on LTC?

The office computer does not crash at all. It is solid. I was using all powered risers. I don't think it's a power issue. I am able to stay below the killawatt meter.

Does the office computer crash every morning? Maybe your computer is doing something else and used more power.

Try powered riser on your mining rig (with 6 GPU).

MSI Z77 GD65
MSI 7950 TF3
8GB RAM
Lepa 1600W PSU
Windows 8
Catalyst 13.1
All powered extender cables

I had six cards MSI 7950 TW3 working just fine. After the third day, it kept freezing, resetting or shutting down. Killawatt said I was going a little over 1600 watts. I thought it was consuming too much juice. So I turned down the cgminer tweaks and got it below the wattage of the PSU. This time it kept freezing so I reinstalled drivers. Still had same problems so I reinstalled Windows 8. I just pulled the card that got sick or dead and put it on my office computer. Then I had five cards working. It kept on freezing. Pulled another sick or dead and put it on my office computer. Now I have four working together on the miner and two in the office. Each time I get a sick or dead card, I tune down the cgminer settings. The four GPUs on the miner are now getting 620MH/s or 620kh/s in Litecoin as well as the two in the office without crashing. Thought it might be heat problems but the two in the office got up to 85 without a hiccup.

So two of the cards do not cooperate with the others. I don't know why. The two GPUs in my office computer run cgminer like a champ. I thought it might be the motherboard of the mining rig so I tried different slots and different extender cables and swapped different GPUs around with all the GPUs. The motherboard works fine with other GPUs and cable extenders. Just not the two.

TLDR: two of my GPUs can run cgminer in the office computer perfectly but crashes on the miner rig. The miner rig motherboard and extender cables work fine with four GPUs but not the two that is now in the office.

What do you think?

Thank you.  Smiley

A modification based off your suggestions. I will definitely consider a DOM or 2.5" SATA drive or BAMT via USB. The 3.5" is there for reference. I could have made it really boxy but I like the frame sticking out a bit. It gives it some flair.

And for vertical GPU placement, it can be positioned this way.

Yes, some GPUs blow air out in both directions.  The fan direction I currently have in the model is just to get a feel of the design. I can change the direction of air flow depending on the GPUs I use.

That's exactly how I arranged my rig  Grin

But I am wondering about the fans in your and some other rigs.

The cards (at least in my rig, 4 Sapphire 7950s) blow hot air into 2 directions:

1. to the opposite side of the cards as where the fans are, so through the bottom of the card and so unfortunately to the fans of the next card which suck in the hot air from the previous card
2. out of the back of the card.

In your pics it looks like you have your fans directed to the back of the cards. If you blow with your fans in the direction of the back of your cards, I think you blow the hot air back into the card.

So what I did, I put one large fan in FRONT of the cards to blow cold air through and between them , which works very well. Another advantage is that I need only this one fan to cool the cards, the mobo and the PSU.

Yes also after three days, I scaled it down to five cards. It runs so much cooler. I followed the directions provided by ssateneth to get six working but it kept on shutting down on me. I'm guessing too much power draw on the PSU. I had a killawatt showing over 1650w. Then I lowered the intensity to 18 and underclocked a little to get it to has ~600kh/s per card. Killawatt showing 1550W. Still crashing and shutting down. My guess is that the drivers are corrupted. So I reimaged the whole thing. Still crashed. Switched to five. Crashed for a bit. Turned down the thread concurrency to 21712. Now it's solid with zero hardware errors. So now I'm thinking if I should go back to six with zero crashing if I set the thread concurrency to 21712. But with five it runs so much cooler!

TLDR:
Six cards crashed. Switched to five and runs cooler. Now thinking maybe six cards crashed because of thread concurrency.


TLDR

were you still doing this setup for a week? I just tried it myself... and I have to remove 1 card to make it work after 3days...
