Topic: GUIMiner-scrypt: A GUIMiner fork for mining scrypt chains - page 21. (Read 994016 times)

I'm only going off what I've read with my Z77A-45's. They have 6 PCIE slots and 1 PCI slot. It can take 5 cards without any issues, but the 6th card always shuts down 2 other cards, until you do a presence short.

So even though Windows recognizes there are 6 cards, I would still need to do the presence short to get it to work? I'm about to re-read the manual and see what modes the PCI-e can run in. It seems that 1x slot gets finicky for sure, so I'll attempt to short it out a bit later today and see if that fixes the problem. (:

You may need a presence short on that 6th card. Google presence short, and look into it - many motherboards will force only 5 cards, but there is a way to trick it into accepting the 6th.

One of my 5 cards keeps showing that it's reporting errors in Windows. They were all working fine yesterday until I tried adding a 6th card to the machine. I have a Gigabyte UD-5 motherboard with a 1600W LEPA PSU and all cards are on risers. When I put the 6th card in, Windows recognized and added it, then disabled two cards because they were showing errors. I've removed the 6th card and am still getting errors with one of the 5 so it won't mine. :-/

Also, one of the 5 cards is showing as if it's working fine, but when I run GUIMiner, it gets to about half the hash rate of the other cards, runs for about 45 seconds, then crashes the driver and cgminer. Nothing changed settings wise from when it was running just fine before adding the 6th card and subsequently removing it. I've used the "powertune" feature to go -5% on power as my cards are voltage locked and I'm trying to squeeze #6 in. Honestly, if I can only get 5 cards running then that's fine as I'll be near maxing out my PSU's wattage rating if I get a 6th in. Mostly just concerned in getting the conflict to go away and get the "working" card to stop throwing errors and not hashing.

Considering wiping Windows, reinstalling, install all drivers before internet is connected via USB, then connecting it up to start mining. This worked just fine for 5 cards at initial build. If that doesn't work, I'm going to give Ubuntu another shot, though I'm trying to fix this for before the weekend is up as I don't have much time before leaving for another week of training. Stupid work getting in the way of my money printing press!!!

The stratum proxy was working fine until I rebooted my computer.  Now it throws errors.  I have restarted it twice and nothing has changed. This is what I am getting.



Also in GUIminer-scrypt alpha it is pointed to coinotron.com:3334, do I need to point it somewhere else like a local host to get it to use the stratum proxy?

So the tech thinks it's not too hot hmmmm... does the tech get to repair your machine when it melts?

Seriously, take the bottom card out and build another rig OR buy an extender for the bottom card OR severely lower your hashrate.  You're going to kill both cards.

- Afterburner, no. Watching temps/fan with Trixx but no adjustments of clocks etc yet. Recommendations welcome. (Do I void any warranties when over clocking?)
- Not sure what power I'm at. Again tell me.
- Getting ~550kh per card.

They're in a case (butt up next to each other) I can run the bottom one by itself and runs at 70 C but whenever I put the top one on. Bang, up to 100 C. Just installing another fan now straight onto the gpu.

I'm aware they can run hotter than average cards, so I asked a tech at a PC shop if it was too hot and he said "Is the card failing?" and I said no. "Then it's not too hot." But we both agreed obviously lower is better.

Any recommends welcome.

[Update] I had the fan on the side of the case on extract. I flipped the fan around and temperatures dropped by a couple of degrees C. (so still 97 C). Using GUIMiner=scrypt 'high usage' but even on low usage the temps get to in the 90s

[Update 2.0] I'm glad i trusted you guys and myself (and not the PC tech guy.) After dismantling I found my newbie error accidentally pushed the gpu into the PCIx4 slot instead of the PCIx16. Fixing that brought the temps down to 88 C and below 100% fan speed.

Thanks, will use this if I quit mining bitcoin and start mining ltc

That is normal at that intensity, above 15 is "no desktop usage possible", try setting your windows theme to a high contrast one, it will reduce some lag and sometimes gives you a better hashrate!

Hi Taco,

First let me say a BIG THANK YOU for providing us with an easy way to mine LTC. Now my issue - whenever I start mining the pc becomes unresponsive. The mouse will move like 3fps, windows open very slow etc. It still mines though. Current settings are int 19, worksize 256, TC 21712. Temps are fine - 71C on the GPU, 71 and 73 VRM1 and VRM2. I have tried lowering the int but it isnt helping. Any suggestion and wisdom highly appreciated.

System specs:

OS: Win7 x64
Sapphire 7950 ( 2nd one coming soon ) using 13.1 drivers
ASrock 970 Ext4
8GB 1333 Single Channel
Sempron X2 190
750W Seasonic

indeed, those temps are way too high. reference VRMs are rated at 5000 hours at 100 deg C (208 days). you'll likely kill em before that though. play with the intensity setting. my 7950 drops 10c when I drop from 20 to 18 intensity, with a loss of maybe 30kh/s.

Good God.  Either undervolt, throttle back the clocks, lower intensity or remove a card.  You'll lose more money waiting on an RMA than you will with 20% less hash.

how to set up automatic switch to the alternate pool?

Too hot.

Are you using afterburner?  You at 20% power?  What hashing speed are you getting there?

You need a fan bro.

Looking forward to v0.04. GUIMiner-scrypt has helped a newbie like me stay away from the console.

Might the next version include checkboxes for:
--auto-fan
--auto-gpu

As I'm concerned I'm running my cards too hot. 99C and 100% fan. Or is that expected? (2x 7950s)

AFAIK, no failover pools can be set up on the GUI, unless you're able to do that with a command switch? In which case you would put it in the "Extra flags" box.

Is there a way to set up a failover pool with the GUI?

I'm impressed with the GUI and would prefer it to the command line, but the only negative seems to be that one is unable to setup failover pools. Of course, it could be me not knowing where to set it.

If you have your video card drivers installed but not the AMD SDK, guiminer crashes immediately.

It's okay, I herp-derped on this too.

Tacotime,

Will GUIMiner be updated to include cgminer 2.11.4? Just curious.

sorry have not seen you are working with nvidia
you need a cuda miner!
hope that tacotime will ad it to his guiminer.
maybe you get some info out here:
