Topic: Primecoin GPU miner: 9.1 CPD on a 280x / pool / 2% dev.fee - page 25. (Read 100962 times)

I have trouble starting the client:



This is on a W8x64 machine.The hw key I sent was generated on it.
Any ideas?

Any news on working with a pool?

My statement was, that I like this coin compared to most coins. 

"Pump and dump" is a well used phrase on these forums, it defines a majority of coins released. 
Also, ignore the troll box,  it is in your own best interest.

This is the 2nd time today I see the someone saying "pump and dump coin" exactly coincident or it was you on mcxnow chat today?

I have 3 x 290x running. I am sitting at  4.7 average cpd.  Increased pretty well from original numbers. Times on all 3 cards are 155-185, but vary a bit.
Miner paid for itself easily and I am still getting blocks, but they have slowed, likely because of raising difficulty.
Cards are at 1075/1250.

Is there an improved 290x client coming?  I would love to see these numbers improve.

Thanks primegpu guys!  I like that I can mine a good coin and be as profitable as the pump and dump coin of the day.

Hello Gents,

I just want to report my past week experience with this miner over here.

Note: My mining rig consists of two Sapphire's 280x Toxic cards for which default clocks are 1150 MHz on core and 1600 MHz on memory and default voltage is 1.256V per card.

Initially I have started to mine using following clocks: 1099/1000 (these settings I have been using on my cards while mining the MAXcoin - Keccak algorythm, which is not memory intensive as it is based on SHA-3 algorythm). With these settings and voltage drowned down to 1.088V I have got almost all the blocks I have reported within this forum.

Once the version 1.02 and 1.03 has been released - I have started to fiddle with the settings and clock, which in fact has enabled me to raise the cpd from 2.65 (2 cards) up to 3.07 per day. Times per GPU lowered down to 175 per card.

While fiddling with these settings I have at the end come up to clocks of 1150/1600 on each card tested with all cpu usages certainly - what yielded me in its whole (4-5 days) 4 10-chains and 1 block found compared to the first phase (about 7 days cca) with initial settings and default cpu usage set that yielded me in total 12 blocks and 9 10-chains...

Based on above you can make s lil bit closer picture on how much is worth to maximize the estimated chains per day if you compare it to the settings where its "actually yielding something"

P.S.: I am not a noob in clocking, undervolting, nor mining at all - nor when we consider the XPM mining in general. I have been very closely monitoring all values throughout the several clock settings as well as for the CPU usages tested and you should not doubt the fact that all values have been kept within the STABLE values e.g. there has been no spikes or lows fro the GPU usage, nor GPU core throtling based on temperatures or CPU usage related throtling in general. Still - the actuall setting that you notice to be a "yielder" can be a game changer.

I am sure this can differ from card to card specific basis certainly - you have to gather your own test results yourslef in order to make sure some settings is ideal for your cards with this miner.

These cards are not supported, sorry.

Can I use this miner on 5970, 6950 and 6990 ?
What is efficienty on these cards?
Thank you.

No not stable to game. I artifact like crazy. Have to clock back.

Oh ok.

Are those clocks even stable for gaming or do you down clock it when you game?

Cant give you an accurate number. I've had the miner for 4 days now. So far found 5 blocks.

Got super lucky one day and found a block in the first 30 mins.

I keep stopping it so i can play diablo 3. It's my weakness.

How many blocks and 10-ch have you gotten in 24 hours?

I'll give a try with those clocks...

Water cooling is great with running multiple cards in a close case. Single card, not so much.

Air cooled

Dont care for water, tried it in college and became too much of a pain in the ass.

Though i do have an extra 80 MM blowing on it from the front, a 120MM blowing on it from the side, 2 PCI Slot coolers top and bottom of the card to pull heat away and a 120 MM above this near the CPU blowing out.

Still pretty quite too.

That's insane...air or water cooled?

1306 Mhz
1218 GPU Voltage
6950 Mem
Power target 120%

What's your clocks for the core and mem?

My system refused to install any of the 13.xx drivers, so I had to reinstall 14.3. Don't wanna reinstall Win 8 for now, so that should do.

I was able to squeek a few more CPD

Few more MHZ on the gpu clock and a small increase on the voltage to make sure it was stable. Only went up 2C

Synced...though, I found out it's not mining some other coins properly either.
Gonna have to reinstall it seems. And yeah, I tried the cleanup utility, will have to do it all over again.
