Cryptocoin Mining?

[Silverforce11]

Lower intensity is nice, I can run World of Tanks @ 60 fps maxed while mining, 1 card at 20 intensity, other card at 14 (~620 kH/s).

 

[taq8ojh]

Stop teasing me with your experiments, my card still hasn't even arrived (into the country) yet!

 

[fleshconsumed]

Are you getting a lot of HW errors in cgminer? If you are, then the intensity could be too high. If you can maintain the higher intensity while keeping HW errors and rejects low, I would trust cgminer. Wemineltc shows wonky readings for me sometimes as well.

Yeah, that was it. I came home, upped intensity and got lots of HW errors. My card was slightly overclocked, so I put it to stock, and tried upping intensity again and it still got me HW errors. What the hell? Why can I not go past I 13 intensity?

interesting I might have to try that; only have the one card; but I mine better with intensity at 12 and threads two LOL........not sure how that would effect me in gaming....will have to test

 

[geokilla]

I can't even watch MKV and RMVB videos with intensity of 12 in Media Player Classic... Do not want to degrade video quality... Need to get myself that dummy plug today!

What's cool to you?

I typically aim for 80C, but willing to go above. I see people in here running their sh!1 @ 90C and I'm like D: I know these cards are built for it, but what's the industry standard, rule of thumb, etc. for temps?

I try to stay at 70C and under for those HIS cards because I can hear the fans once it gets over 75C since the other components are watercooled.

I personally try to keep anything CPU/GPU at 70C and below. i know most people will say 90C+ is fine but keeping them cool has other benefits such as lower power consumption.

Have you done the "setx GPU ALLOC" thing at the command prompt or in your .bat file? Also, what is your thread concurrency?

Don't have setx GPU ALLOC in the batch file. Concurrency is around 8K (don't remember the exact number) since this is what was recommended for 7950. I'll try setting it higher when I get home tonight.

Do I still need to set the --shaders 2560 in the parameters?

If you have already done the setx GPU ALLOC thing in the command prompt (I believe you only need to do it once), up TC to around 24000. Don't set the shaders if you are setting thread concurrency manually...and a 7950 doesn't have 2560 shaders FYI, it has 1792 or something like that I think. You're giving your 7950 false credentials lol

 

[IEC]

7950 = 1792
7970 = 2048
290 = 2560

 

[f1sherman]

Rule of the thumb is not to mess with --shaders, only tc.

 

[KlokWyze]

10W, max. Less if the HDD spins down regularly.



290's can run hotter than 79xx's.

Seems the 7970 tops out around 80C, 290X's go up to 90C+. 6970 and 5870 get warmer than 7970 due to the older 40nm process.

An enclosed case actually can provide better cooling than a semi-open one. Completely open, ok, as long as there's good airflow in the room (large fans) then I guess it's best. But cases can provide directed airflow, which is better than random airflow.

I'll check that link out after I get through my work emails today. That definitely makes sense for cards with directed airflow, which I have one of (sapphire 7970). My other 2 are Gigabyte 7950's, the quintessential non-directed flow cards.

I try to stay at 70C and under for those HIS cards because I can hear the fans once it gets over 75C since the other components are watercooled.

My rigs are in my basement so I don't really care about noise, though the Sapphire can get REALLY LOUD. I'm not kidding, sounds like a hair dryer when temps get above 85C.

I'd love to get some new cards and make another rig, but it doesn't look cost effective at all. Might as well just buy coins at this point. Though if BTC has another huge surge and settles significantly higher than I probably will buy like 4x 290's.

Anyone know what's up with Coinye? I wanted more buzz from it, but it looks to be slowly fading. It will spike if it gets on an exchange, but how long does that bs take?

I'm at 77C on Core and 80-81C on VRM temps mining at 755kh/s on a 280x.
Is that a decent VRM temp ?
Also, Looks like doge is making a jump back at 38 satoshi.

That's really good temps for the hash rate you're getting...you're almost near a stock 290!

What are your clock and miner settings?

 

[Freaksterz]

Intensity 13
TC 8192
-g 2
--lookup-gap 2
1085MHz Core and 1500MHz Vram
Core voltage at 1075mv undervolted from 1125mv

I'd say those are very good mining temps.

I've been lightly playing around with my 290x's.

The warmer one I've been undervolting but still haven't seen any change in hash. It's now -31 core mv and AB reports ~0.95v. The other is still stock with a bump in memory.

I bumped the fan up to 65% from 55% and they are running at around 1.75 MH/s. One is still 120 kHash stronger than the other for some reason, perhaps one is elpida and the other hynix. They both (memory) clock up the AB max, but the sweet spot was 1490 MHz.

I just noticed that one of them is now under the 90c, the other is apparently still a bit too hot.

~0.95v 800 kHash (undervolted 31 mV)
~1.05v 920 kHash (stock except 1490 memory)

I know that 7950 is 1792. I have since upgraded to 290. I was simply saying I have changed the number of shaders in the parameters after I upgraded to 290 but left the TC the same.

So is consensus to remove the --shaders parameter at all?

I guess I'll be playing around later tonight...

I posted a question on my pool's forum, but I want to re-post it here as well. I'm having issues with unpowered PCI-E 16x to 16x riser ribbons on my Asus P8Z77V-LK board with 3x Sapphire 7970's.

For whatever reason, only the first PCI-E slot (top most nearest the CPU) will work. The other bottom 2 slots will generate Code 10 errors on the 7970's and drivers won't install. I've mixed around the risers and the 7970's, so those are not at fault individually.

After a couple hours of tinkering, I gave up. I pulled the P8Z77V-LK board and replaced it with the Gigabyte FX990 board. I used the same 3 risers, and everything works.

Any idea why the risers won't work properly on the Asus Z77 board?

Does your Gigabyte board have a molex power connector going into the board by any chance?

That's the only thing that comes to my mind.

It sounded like you were still talking about the 7950.

Yes, remove the --shaders and set thread concurrency manually to about 32765 for a 290. I use 24440 on my 290s and get about the same hash rates as using 32765.

Just my luck. I made a doge wallet for deposits on cryptsy and first my wallet crashed when I tried to send coins with the encryption password. I got it to work by running in windows ME/2000 compatibility mode, and then at cryptsy doge is completely missing from the lists. The whole coin is missing from their site.

It appears to be full of complaints about losing coins on trades. Be careful. To me it looks like a mine field.

Easy, add an entry for Bitcointalk with your user name. And suggest they email your heatware email if they have doubts.

Then if they won't deal with you without you sending first, they're probably scammers.
