committing an experimental --algo=blake feature, please run with with same kernel configurations as for keccak.

Only 56 MHash/s on GTX 750 Ti, but from here on out things can only improve... At least CPU and GPU agree on
the results.

I am not sure about the difficulty to target mapping. I am currently using the same code as for Keccak. I will
have to inspect the blake cpuminer to see how they do it.

what hash rates are AMD miners getting for blake256?

Christian

I just tried on one pool Blakecoin EU1 pool, I get only boo's.
the hashrate would be max 130Mhash, I just checked with the big amd electron's sucker (which doesn't seem to use that much on it),
ouch 3.25GHash/s

Will the CUDA 6 release have any impact on mining?

so far it's a negative impact. So CUDA 6 RC is a no-go. There are serious
performance regressions for some kernels, and no additional gain for code
compiled specifically for the 750 Ti (Maxwell).

the guy setting up GPUcoin apparently has a supplier selling them, wont say who or how much.

my idea is you have a case that stores like 8 gpu's
sit it next to your pc

ribbon cable from pc to gpu case.
so in tern you have a gpu box and your pc. plug the gpu riser in to the pc and the gpu's would be usable on the pc :-)

Stop teasing, already super excited lol

What was your bat when you autotuned it?

The exact same, without -l t128x2

Their making a riser bank.
It's a single pci-express that slots onto the motherboard. It then has 8 riser cables coming off it to gpu sockets

Similar to the old pci-x server risers, but separated by riser cables

Who is and how much for it? Cheesy

I want one :p

keeps doing it for some reason. ooo well quick read through and im up to date.

on another note, im converting the amd miners to the nvidia side ;-)
gtx 750 has opened up some real door ways.

even to the point of having a single pci-e go to 8 gpu's using a riser bank
and as stated a few pages back, 270khash/s on pci-express 1 at x16 speed

a pci-express 3 x16 should be able to run stupid amounts of gpus on proper riser boards, aslong as the risers are powered

WHAT???

Clarify that part with the 8 gpus per riser bank plz...

I see, and what cudaminer version are you running?

The latest one Christian posted, x64 for scrypt-jane (seems a bit faster than x86 for me).

Yep.

One issue people gave was the need for such long riser cables. The one solution I gave was that usb3 will run up to 650MB/s

Pci-Express x16 runs at about 250MB/s
So a usb3 cable should be able to run more then 2 cards to a main riser block. And if anyone could figure out how to get a thunderbolt cable running the link, it will run 1.25GB/s which should be fine to run 5 gpus from a single block at the same speed as paid express x16

When the bandwidth issue is fixed, in theory you should be able to run lots of cards from a single slot. Maybe an external gpus box with its own psu? Hmm be a good idea

Yes, as soon as the bandwidth usage by cudaminer is reduced this will work very well

I max out between 3.7 - 4.0 Kh/s.

How're you getting 5?

The boost clock of my card goes to 1032mhz (no overclock), factory has it at 941mhz so I guess I am a bit lucky.
Things like CPU speed really affect it if you are using -H 1, might be a part of it.
Perhaps higher -L values work for you (autotune it!), for me it didn't.

Oh man, thanks so much for this.
I've read about 150 pages looking for up-to-date info on scrypt-jane settings but still couldn't get a working one after hours of trial and error...
You wouldn't happen to have something for the 750ti and the 780ti?

For the frequency at which all this esoteric and ephemeral knowledge is being tested, published and forgotten after an update, you'd think there would be a collective bounty on a well-maintained repertoire of optimized settings for all common gpus... I wouldn't mind pitching in.

I do indeed not have settings for those cards, sorry.
Every card is a little bit different, autotune will probably give good results.
There has been a wall of settings, on some google doc, it outdates too quickly however.

I see, and what cudaminer version are you running?
