Revitalize the american economy AND secure our energy needs. build 20 new reactors a year while taking as many offline. While doing so, upgrade the ENTIRE electrical and IT infrastructure. This would create millions of jobs and secure our future for decades.

Those who are opposed to nuclear need to do their research, it is the cleanest and most efficient power generation BY FAR. Forget all your old assumptions about waste, etc.

NEW nuclear plants are extremely safe and extremely efficient. I hope the US gets off their asses and hands some of the bribes back to the oil and gas industries and starts building reactors by the dozens.

Oh and UPGRADE THE DAMN POWER GRID! we lose more there than anywhere else.

Nonetheless, deregulated electricity is a joke, capitalism NEVER works when people HAVE to consume a product. It doesn't allow for proper interplay of supply and demand which is necessary to a truly free  market.

rant over. The US is just a stupid greedy nouveau rich kid most of the time. Doesn't know what it has or how to use it.

This new atiflash will work for linux, correct? It's one of those dos bios flash programs I assume. I usually have a hard time figuring out how to make it work, but I'll get it eventually.

I just want to be able to lower the memclocks and crank up the OC at stock voltage with cgminer like I do with my 5 series cards.

I'm building this rig for my dad and need it to be pretty stable so I don't have to go over there and work on it all the time.

Hell I can't see any stability issues with water cooling unless I go for a crazy overclock and I'm not going to do that. I jusy want some power savings with the lowered memclock.

I'm bumping again.

PLEASE PUT YOUR DONATION AT 3% FOR ONE FREAKING WEEK!

C'mon guys it would be a nice thank you to Inaba for maintaining a pretty sweet pool and help keep him motivated when things are a pain in the azz.

Not that he's not doing a great job already, but let's do this!

Again, I don't know Inaba at all and have no relationship with the guy outside of these boards and mining his pool the past month or so.

I just believe there are too many "takers" sometimes in bitcoin and we should support those that contribute positively.

seasonic x1250 will do it.

I'd be happy to even just turn off merged mining if that helps man. I am also VERY happy to donate the namecoins to the pool for as long it takes and anyone else who bitches can just STFU. They have no idea how little money you are making if ANY on this pool or most pool operators in general. I know some nefarious ops have stolen coins and it appears deepbit, etc. should be doing okay due to volume and guaranteed donations(I don't know that for sure and begrudge NO ONE a profit).

Anyway I think you deserve a sort of "DONATION DRIVE" and I'm starting now. I don't have enough coins to just throw you a stack and have put some serious coin into my farm and just started getting it going(seriously like for 2 days without issue).

I am asking everyone in the pool to up their donation to at least 3% for one week. Come on folks, this is not much for us, but at almost 400 GH/s average at the pool, it's like doubling Inaba's farm for a week. It would give him effectively 12 GH/s of the pools resources(400 x .03) for a week.

You figure if we can have a good week of blocks, we should technically average I think 5 or 6 per day at current difficulty, but let's say we find 50 blocks that week. Inaba would get about 75 coins that week.

I think it would be a cool gesture and something we should all do periodically. For those of you who already donate at that level then kudos to you.

(I have given 1% from the beginning.)

So I'm going to go change mine right now to 3% until next Thursday. I'm not lookin' for props, but urge everyone else to do the same!

I'm also happy to give Inaba permission to look at my accounts and verify that I have done so if he chooses.

jjshabadoo and jjshabadoo2.

It has given me nothing but headaches and I highly recommend against it, but guys like Jimm_64 have 30 GH/s farms and he uses the paper clip thing and it works fine for him. I used lian li PSU adapters and they have still driven me crazy.

If you're only working on a one or two card rig then go for it. If you want to go for a rig with 4+ cards I say avoid it like the plague.

No, I never solved the extender issue on the asus P8P67 WS. I have had four 5870's plugged directly into the four x16 slots at 950/160 hashing away without issue for over two days with an ultra kaze fan blowing through them from behind and one angled above to blow some air onto the top and in between the cards.  See my previous post for temps, wattage and hash rates on that rig.

After nearly two days of work I was just done with it and besides, I won't get any better OC with extenders. Better temps are highly likely of course, but downtime and exces troubleshooting are not worth it to me.

My main advice to you if you expect to try with extenders is to at least leave one card on the board in slot#1 and then maybe you'll get away with extenders for the other slots. If you have an open rig, you should still get great temps.

Also, the whole booting choice of uefi or normal didn't seem to matter except I never got it to boot with extenders under non uefi boot, but I DID get it to boot at least once or twice with uefi boot. This with 16gb flash drives and linuxcoin final. Maybe the prior version of linuxcoin would work better?

I just wish one of our resident linux programmers/experts would make a newer version of linuxcoin. BAMT looks great but is too limited. Especially since they won't support cgminer which is the miner of choice for most of us.

Can someone just create CgminerCoin? I wish I had the time to do some tutorials on linux and find the best distro and just create the ultimate linux mining software with detailed tutorials for various set-ups, multi-card, extenders, etc.

From what I can tell so far, the most serious miners are using a narrow range of cards and mobos. I don't think this distro would need to be tested on everything or be stable with every miner who has a rig doing 200 MH/s.

Give us a linux distro designed for 58xx series and 59xx series cards and maybe one for 68xx series and 69xx series cards for maybe the top 5 mobos.

the MSI 890FXA series
the ASUS P8P67 WS series
and maybe the big bang and a few other boards that have 4 or more x16 slots.

Hey, any reason we have these couple of miners with like 100GH/s who seems to come and go from the pool? Kind of freaks me out. I'm just a noob mostly still so I'm not accusing anyone of anything, but seems odd you would move THAT level of hashing power around all the time unless you were attempting to hop or possibly something more nefarious.

Now maybe just connection issues, etc. but does it freak anyone else out and is there any reason to wonder about this?

how many Jimm? you didn't say in your post.

I just used the reset to default. F5 I believe for that mobo.

I'm sick of f''in around at this point and don't have the time. If BTC drops below $2 I will need to reconsider efficiency, screw it until then. 100% up time is my goal.

I'm buying some used parts for a practice/test rig that will go on my tech bench. When my patience has been restored, I plan on using that to slowly test settings, etc.

I'll be happy to pass on anything I learn from those tests.

I have all cablesaurus cables and still ran into issues as posted above. I have never bought from anyone else and also 4 have burned out on me in the pci slot but I believe that is related to trying to use two psu's or bad power fluctuations where the miners are. Even though I was told that two psu's should not be an issue, I would NEVER do that again. Even though Jimm64 has 30 GH/s of mostly 5970's, with extenders on MSI890FXA-GD70's with two psus and he says he is mostly rock solid. I copied that model and have been slaughtered so far.

EXTRA NOTE AND THIS DESERVES CAPS, CABLESAURUS WAS EXCELLENT AND EVEN SENT ME TWO NEW EXTENDERS AT NO COST AND WAS WILLING TO PROVIDE TECH CUPPORT TO HELP ME FIGURE OUT ANY ISSUES AT NO ADDITIONAL COST.

Cablesaurus is a GREAT BTC vendor. If you're going to bother with extenders, then go nowhere else in my opinion.

BTW my solid rig with extenders actually just started to lose hashing power again and looks like it at least needs a restart, so i'll hold off on my assessment of getting ANY rig to be solid with extenders.

This site really needs its own hardware wiki for individual hardware parts and known rig combos that WORK and what stats to expect. Would be a huge resource for all of us. The current online hardware wiki is crap and out of date.

I'd also like to see the site create a section for detailed guides. I think they could charge a monthly rate for access to such things, sort of a VIP membership, paid for in BTC of course

Okay, reset bios defaults and looks okay.

Never touch mining rigs again unless they break or stop mining.

Geez man, this is going to kill me...lol.

Jeez, i just had to restart my rig and cgminer starts without issue and then shits the bed when longpolling tries to start and I get a pool communication failure.

I tried to turn off some bios settings to save wattage on my ASUS P8P67 WS motherboard and this error starts.

pool 0 communication failure and then my internet connection fails. Port is working and works fine after reboot and then fails once I start cgminer.

Any ideas?

I just placed a scythe ultra kaze behind the cards and one kind of angled over the top and that beast has been cooking averaging 1.8 ghash at about 780 watts with kill-a-watt meter and that is without turning off any power saving features yet because it was 430am and i was just happy it was working after two days of wanting to sell all my shet on ebay...lol

The MSI 890FXA-GD70 seems to not mind extenders, but only a couple and I've noticed you usually need slot 1 populated directly and then you can screw around from there. For example, a rig of mine that has been rock solid for over a week.

MSI 890FXA-GD 70
AMD sempron 145
2gb ram
slot 1 actually a 5870 on powered extender but no molex connected to it
slot 2 5870 directly connected to pcix16 slot
slot 3 5970 on powered extender with no power to it
slot 4 empty
slot 5 5870 directly on the board

when I say slot I mean pci-e x16 only

turned off as much crap in bios as i can think of to save power and it does 1.8 to 2 GH/s at about 750 watts average.

settings in cgminer as follows in my startminers.sh script:

./cgminer –o http://us.eclipsemc.com:8337 –u username –p password –I 9,9,9,9,9
gpu-fan 85 gpu-engine 950,950,820,820,950 gpu-memclock 410

Thing just beasts along with good temps. TIM and thermal pads replaced on 5970, 5870's just stock from that ben's outlet sale. man i wish ai bought more of those, they have all been great out of the box except one has no fan control. I got 8 and they all do 950.

on the asus board with the 4 5870's all in the slots. I have them at 950/160 and they have been fine overnight worst card temp right now is 74c lowest at 62.5c
They are also in an old case lying flat with sides still on. I'd probably be doing better with temps once I get the gumption to just rip it out and put the mobo on a wooden board with motherboard plate underneath of course and just line up two kazes behind the cards.


I also need to mess with the memclocks on that cgminer script, but have just been happy its been stable for a week so I don't dare.

I keep saying we need more sticky's/threads with just pure specs and settings for folks.

Sorry man, yes that is the exact board i am using ASUS P8P67 WS motherboard and i had the same exact issues you had. tried booting uefi and without, nothing. Then suddenly I would get into linuxcoin, set up, mine and then gpus all dead and then can't get back in. I re-loaded linuxcoin 15 times at least over past 24 hours. then i just said F it, i only have 5870's for that board, so i threw them all on the board without extenders and BAM, 100% stable since

I just want to say, I have bought a ton of stuff from Madhacker in this thread and it all has been as he stated it would be and shipped as quickly as possible.

I'm waiting on his 6970's and water cooling blocks and a few other things I bought from him, but everything else has been on the level.

He has been a solid person to deal with and I don't know him from Adam. Just an honest review.

Exactly right guys, the extenders are killing me. I just whacked in 4 5870's on the asus p67 board and BANG, no issues. Even able to take a card in and out. WTF is wrong with extenders and why do they cause so many issues? It's killing us on my other rigs too. I've realized the cards do fine even in close quarters on the mobo as long as you blow some extra fans through them and screw the overclocks. Get what you can and just f'in leave it alone.

I do have those 5870's at 950/160 and they are fine. worst temp is 71c. These are stock 5870's from ben's outlet.

I do have one box with one card on an extender and its been fine. I'm going to move toward always putting the first card on the board in slot 1 and then a card in the last slot. Open cases of course, basically mobo trays nailed to boards or whatever and then maybe put one more card on an extender in slots 2 or 3 or 4.

I've also learned we are getting killed by trying to use two psu's. We have two rigs with 3 5970's connected to two seasonic x750 gold psu's connected with a lian li PSU connectors and those bitches fry pci extenders like they're going out of style, powered or not. Nevermind they are NEVER stable.

So I'm going to either unload the 750's or actually, probably cheaper to just buy one more motherboard, cheap ram and cheap cpu.  Just a shame to have boards like MSI 890FXA-GD70's with only two cards, but F it. We can mine for a while and then maybe to decide to screw with one rig at a time.

Sorry for the long post, but thanks for the help and this noob has learned his lesson. Don't get too fancy maxing shet out when you're just getting started even if you think you know hardware, because mining is its own animal.

I can build and overclock the S out of a gaming machine, but so what.

anyone have any insight in this uefi boot versus regular if you're using linuxcoin on a flash drive? seems it really will only boot in and then I can't ever reset it without a black screen hang on second boot.

I've got 4 5870's on x16 extenders and the powered molex into the mobo for extra power to the pci lanes.
ASUS P8P67 WS motherboard
1250w seasonic x1250 gold
4 5870's
pci x16 extenders
couple of scythe ultra kaze blowing through the backs of the cards
2gb ram
Intel celeron G530 cpu
16gb flash drive with linuxcoin final

have the bios on average power settings also figured maybe the low power thing could be screwing me.

I'm wondering mostly if the whole uefi boot has something to do with an ubuntu flash drive as the OS.

I know, maybe i need to switch over.

Now i'm having a hell of a time with an ASUS P8P67 WS motherboard and 4 5870's on extenders. they were doing great for days on an MSI 890FXA-GD70 until the damn lan port went up on me. I had those suckers at 950/160 cranking along. decided to mess with the rig to put two fans behind the gpu's for better cooling and here I am three days later with jack shet to show for it.
 
Also this damn asus board is freaking me out with the uefi bios i don't know which settings to do for the flash drive with linuxcoin, uefi boot or regular or what. I can get in with a fresh install, gpu's then hang. I try to reboot and then after linuxcoin graphic, black screen.
