Open Fritz in classic mode select the engine tab click on create UCI engine click on browse select the lc0.exe click on ok.
Default network is automatically configured and in engine parameters change the backend cudnn to fp16 for better performance for 1600 series GPUs.

And please suggest strong network for this GPU

use 20b x 256f networks like Leelenstein and T40

Last tests shows that J92-70 and J92-100 nets are the strongest 384x30 nets.
According to some tests J92-70 is the best net and according to some tests J92-100 is the best net

Download link of J92-70:

Download link of J92-100
https://storage.lczero.org/files/networks-contrib/J92-100:

384x 30 nets are the most suitable nets for Lc0 chess engine with strong GPU's like RTX 2060 (min: 4 minutes/ game), RTX 2070 (min: 3 minutes /game) and RTX 2080ti (minimum: 2 minutes /game).

It's a middle level Gpu for Lc0 chess engine. 256 x 20 nets like 256x20-t40-1541 are most suitable for this GPU.
https://www.comp.nus.edu.sg/~sergio-v/t40/256x20/

But at long time controls matches like min:30 minutes/game you will use a 384x 30 net with Lc0.

Lc0 v0.26.2-rc1

▪Repetitions in the search tree are marked as draws, to explore more promising lines. Enabled by default (except in selfplay mode) use --two-fold-draws=false to disable.
▪Syzygy tablebase files can now be used in selfplay. Still need to add adjudication support before we can consider using this for training.
▪Default net updated to 703810.
▪Fix for book with CR/LF line endings.
▪Updated Eigen wrap to use new download link.

If you build from source, note that old versions of meson cannot download from the new Eigen download link. You will either have to update meson or build with -Dblas=false.

For now J92-115 seems the strongest Lc0 384 x30 net.

Lc0 v0.26.3-rc1

▪Residual block fusion optimization for cudnn backend, that depends on custom_winograd=true . Enabled by default only for networks with up to 384 filters in fp16 mode and never in fp32 mode. Default can be overridden with -- backend opts=res_block_fusing=false to disable (or =true to enable).
▪New experimental cuda backend without cudnn dependency ( cuda-auto , cuda and cuda-fp16 are available).

For now J92-190 seems the strongest Lc0 384 x30 net. At TCEC Super Final Lc0 plays with this net.
