Titan V near 1000sol/s

smartbitcoin · January 12, 2018, 10:21pm

after few optimization for titan v, this card can handle near 1K sols/s.

it’s still have 20% potential left.

@smartbitcoin Wow, nice! How are the temps?

smartbitcoin · January 12, 2018, 11:02pm

temp: 64C,
power: 180W
clock: 1600
mem: 2000

For the low low price of 3K!!!

RafalPL · January 13, 2018, 1:46am

very nice but price too high my question Titan XP is good for mining Zec ? how soil/s between GTX 1080Ti?

macperlita · January 13, 2018, 5:29pm

great! second life for a expensive card!

smartbitcoin · January 14, 2018, 7:46pm

Titan xp is pascal. Titan v is volta. Pascal is ILP. Volta is TLP. Titan xp maybe 10% better than 1080ti.

Hi smartbitcoin I just bought some titan xp. Do you overclock the titan xp exactly the same as a 1080ti? So far I am getting 15% more sol than my Zotak mini 1080ti

smartbitcoin · January 18, 2018, 2:13pm

My test is titan V , not xp and I don’t have a xp yet.

smartbitcoin · January 18, 2018, 2:15pm

I assume titan xp should have same OC setttings as 80ti, what’s your sols? around 850 ?

INJurer · January 23, 2018, 10:01pm

What miner are you using?

Here are my results with EWFB. The first two cards are Titan V’s, but the third one is a Titan X (Pascal). Temps are higher as they’re installed one above another in a closed case.

This is at 76% power draw. Can’t go higher than that. MSI afterburnes says the limit is due to “no load”. As you mention there’s a potential for at least 20% better performance.

RafalPL · January 23, 2018, 10:45pm

How much power usage you rig?

INJurer · January 24, 2018, 5:32am

Mine is around 800W, but I’m also CPU mining Monero with a Threadripper CPU on 14 cores.

RafalPL · January 24, 2018, 2:28pm

Very good power consumption i sale this week my two rig and build 4x Titan V

If you still have access to that Titan V, could you do me a favor and try establish the very first sub-second run of Cuckoo Cycle? See this report for background:

Progress report on the Cuckoo Cycle GPU solver
============

UPDATE
------
This document is obsoleted (in part) by photon's 4x faster GPU solver from early April 2018.

Since completing my rewrite of xenoncat's performance quadrupling CPU solver (winning a double bounty)
in the form of mean_miner.cpp, I've been slowly grinding away at porting that code to CUDA.

I consider myself an amateur GPU coder, having previously ported the latency bound lean_miner to CUDA
(and having to pay a bounty to fellow Dutchman Genoil for improving performance by merely
tweaking the threads-per-block which I had naively fixed at 1), as well as my own
[Equihash miner](https://github.com/tromp/equihash) submission to the
[Zcash Open Source Miner Challenge](https://z.cash/blog/open-source-miner-winners.html).
That Equihash CUDA miner achieved a paltry 27.2 Sol/s on an NVIDIA GTX 980,
matching the performance of my Equihash CPU solver. But it did serve as the basis for far more capable
rewrites such as this
[Nicehash miner](https://github.com/nicehash/nheqminer/blob/master/cuda_djezo/equi_miner.cu)
by Leet Softdev (a.k.a. djezo), which achieves around 400 Sol/s on similar hardware.

np, I’ll try it tomorrow and post the result.

noobvie · February 2, 2018, 7:02am

why burning your card? better to keep power less to have lower temp.

INJurer · February 2, 2018, 3:20pm

Hi tromp. I’d like to help, though I’m not sure what should I run. I’m typically using Windows, but can switch to Linux if needed. Have VS 2010/2017 installed.

tromp · February 2, 2018, 4:19pm

Hi INJurer! On Linux, run

git clone GitHub - tromp/cuckoo: a memory-bound graph-theoretic proof-of-work system
cd cuckoo/src
make libblake2b.so cuda30
export LD_LIBRARY_PATH=$PWD:$LD_LIBRARY_PATH
./cuda30 -r 10

and note the fastest Time among the 10 nonces…
