may-be I am too suspicious, but do you really think that the aurora dev will give all the premine to his fellow icelanders if it keep that rate or will just cash out everything for himself ?

the devs have set up a web site detailing the airdrop process and the amount of premine not handed out...

at the Moment it looks like a genuine attempt, mich like MtGox was a genuine attempt of running an exchange *snicker*

So I know glucose failed it's launch but is anyone jumping on its relaunch again?

glucose, that's really what will be needed at 5am... don't know...
I think, I would prefer a psu coin

[bigjme]

Lol I hate the new auto correct on my phone. Gpu is glucose for some reason lmao

So when's nvidia coin coming out? Stupid algo that nvidia cards have an advantage on

That would be a smart algo!

That's not what the AMD legion would say ;-)
He'll make a wallet for it and set a maximum number of clients. Stop pools destroying the coin

6x 750 Ti's (OC'd to stable + BIOS Power Mod)

Pretty please could you edit your post to include the exact make and model of your cards? It helps other people greatly Thank you!

His results are consistent with my 8x Zotac 750 Ti's on Win7. Note that in my testing there was no need for the BIOS power mod since it yielded no increase hashrate or stability, just extra power consumption. My overclocking is +135 core, +600 mem on all 8 cards.

Benchmarking results of each of my Zotacs here: https://bitcointalk.org/index.php?topic=167229.msg5441080#msg5441080

Can you post up more system spec; motherboard, ram, psu...

[rasmanki]

i love cudaminer

i love cudaminer

cudaminer love you too, however it still feels the need to see other people

Wanted to put out my quick findings with the 750ti since I went through a build and learned a bit, hopefully this helps some people.

• EVGA Ftw edition, currently running 320khs for each, 5x cards
• Gigabyte UD3 motherboard, some random 4gb stick of Kingston ram that was cheap on amazon
• I was unable able to get the USB 1x-16x risers to work.  Performance was all over the place, and I got random crashes and instability in Cudaminer.  These same USB risers are now used on a r9 270 rig at 100% speed, so I just switched risers with that machine -see next note
• I was able to get a mix of unpowered ribbon 1x-16x mixed in with powered 1x-16x risers to work just fine at 100% speed.
• I can not overclock memory more then 600mhz
• GPU doesn't have much of an impact on the hashrate
• x86 miner is faster than the x64
• Cudaminer 750ti Settings I saw that work / made a difference:  T10x24 performed slightly better then T5x24  and -H 2 is the best for stability.
• Windows 7 64bit, really wish there was a BAMT equiv for cudaminer though.
• Inside a heated home the 750's do not break 50-55c at full load and overclocked

I do get random OS reboots, but I set my windows build to auto login with the miner spinning up on startup. So a crash or 2 a day doesn't impact my mining for more then 5 minutes.  Still not sure what that is all about...

I added a second gt 780 to my pc now the temp is 82c while the fans are at 100% anyway to lower gpu usage? how many had there fans damaged due to long periods of there fans running at 100%
i downclock my gpu to 1020 core but still above 80c

You should worry about getting cool air into your rig, not lowering the GPU cores

Hey Christian.

Quick question, can I use Cudaminer on something like [Suspicious link removed]?

Do I just set it up like normal and bobs your uncle?

Is there a way to calculate how much ram is actually needed vs the # of cuda cores or something along those lines, for scrypt mining? ie: Would a 2gb 750 mine faster than a 1gb 750?

Regular scrypt, no, but scrypt-jane it might do better than the 1gb one.

Hi, Christian

I have made a small investigation (see below),

Could you make a little code improvement, because now the only way to use cudaminer with screen
is to run pure screen, and execute cudaminer from screen session. It works fine.
But if you want to have the same, but executed from shell script
- there is a SIGHUP signal, which terminates screen completely.

It would be great do have screen <-> cudaminer full operability.

Regards
JK

Would a 2gb 750 mine faster than a 1gb 750?

RAM is only a bottleneck at higher N-factors. For Yacoin that is a definitive Yes.

When Cudaminer does this, attempting to mine afterwards results in a very very low hashrate (usually ~27KH/s on Scrypt). Is there anyway to resolve this without having to reboot the computer?

Any ideas?
