CCminer(SP-MOD) Modded GPU kernels.

Information purpose.  Speeds for Lyra2v2 using SP version around commit 1056.  All at stock mfg clocks.

EVGA FTW GTX960
6,150 kH/s

EVGA Hydro Copper GTX980
11,775 kH/s

Lyra2rev2 was added in 1.5.60 release...

[sp_]

I submitted a bether launchconfig in the lyra2v2 algo. (commit 1103)

The gtx 750 (overclocked 1500 core) is up from 3650 to 4400 (source rednow)
The 750ti unchanged
The 970 up from 9200 to 9400 (windforce G1 standard clocks)

950, 960,980,980ti untested.

please build and test

Lyra2v2 has increased from 0.7 GH/s to 19.88 GH/s today at nicehash.
Mona effect?

[dominuspro]

I have tested all releases of lyra2rev2 with my little rig of 980/2x970/960, win7x64.

I got the best results with versions 62 and 65 around 38900Kh. Followed by release 66, slower by 50Kh. All without I or X parameter.
The difference is most notable on 970.
The best option right now is to use 970 with release 65 and 980/960 with release 69, specifying the -X 30 for 980.

Those are the numbers right now:


BTW the clocks are:
980 G1 gaming: 1450
970 G1 gaming: 1560
970 ASUS strix oc: 1440
960 mini cheap something: 1411
The highest temp and fan rate are on the 960 - 65°C and 65%

Maybe someone finds my data usefull

The biggest Mona pool have 18 ghs Lyra2rev2 hashrate...

This is my numbers. I got the Windforce G1 970 up to 10MHASH
The asus strix 750ti is also peaking over 5

With a light overclock.

windows (x86 with the head at github without the intensity parameter set)

But there seems to be a bug somewhere. The gpu is stopping quite often:

Latest git, the 970 peaks higher but average hashrate is lower.
Maybe the usual scantime issue? Will test as soon as my rig stops crashing (faulty card) :-(

EDIT: no it's not scantime.

When I am running in quiet mode and remove cpu verification, it runs at full speed.

Here is what I am getting off commit 1103 compared to commit 1056 after 1500 accepts

GTX960 dropped down to 6140 from 6150.
GTX980 dropped down to 11760 from 11775.

SP one thing that I noticed, after around 200-250 accepts the 980 was peaking out over 11800.  I was kind of excited but it settle back to the numbers posted above.

BTW, how do you post screenshots?  Do I need to host them somewhere?

I can't reproduce this on my system with release 69.
But then I only have one card.
Will try to compile the latest commit tomorrow.

[sp_]

The problem seems to be that when the CPU is working in the backround, the cards are producing very little.

[sp_]

Submitted a possible improvement in lyra2v2. The same clocks as before.

The rig is up 1MHASH in the displayed hash and less gpu-shutdowns.

[fenomenhaa]

750Ti peaking 5220
970 peaking 10650  r66 is best for 970. other newer releasises lost 1000k/hs in 970.

[crsminer]

Commit 1103 vs rel 69 -- lyra2v2:

750 at 1400Mhz:   4150kh vs 3500kh
750ti at 1400Mhz: same speed or tiny improvment between 5050-5100kh
960 at 1500Mhz:   same speed or tiny improvment between 6250-6280kh
970 at 1500Mhz:   10350kh vs 9500kh

[pallas]

Latest commit is even slower than the previous one on my 970s.
They can barely reach 9000 at 1387 MHz

[lastbit]

Lyra2REv2, linux, just compiled:

750 @1202MHz =~3350 (non Ti)
970 @1303MHz =~8530
980Ti = does not validate on CPU

Thanks,

[pallas]

Curiously, hashrate at the pool doesn't seem to be affected by the apparently lower reported one: it looks to be the same on all the last three commits.
Will report more precise data tomorrow.

Hey all if anyone wants to donate/tip to devs and in general then Protip is a great tool. I just set weekly donations & put bitcoins in the wallet. I am using it to tip djm34 although its miniscule at $0.25/week but its a great tool & it might add up. If you want to tip w/o hassle just check it out at http://protip.is/
