The collider generated (and checked) over 10000 trillion keys, which is double the addresses. I released a new version of the LBC client (1.195) - this fixes one or two bugs in Skylake and Skylake-avx512 detection. Everyone who has either a Skylake CPU or a Skylake-avx512 CPU should update to this version, because later today I plan to put the Skylake-avx512 generator binaries for download. If you do have a Skylake CPU and an older version than 1.195, your LBC will break by downloading a skylake-avx512 binary although you only have a skylake. Same applies if you have a Kaby Lake (as these are virtually the same as Skylakes and therefore want to use the same binary) $ LBC -u New client '1.195-LBC.bz2' found. Finished update run - system up to date.

Guys, can you advice what is the best speed/price ratio from Core i5-i7 CPU family for launch LBC soft? Im going to participate and luckly it's time to upgrade my HW. Thanks.

Depends on your budget. The https://ark.intel.com/products/123767/Intel-Core-i7-7820X-X-series-Processor-11M-Cache-up-to-4_30-GHz is a nice CPU with lots of potential. Seems a 1950X Threadripper is even better. Don't go for Vega{56,64} yet - lot's of trouble - AMD guys seem to need more time to provide sane drivers. If I was to choose some MAX configuration, still in reasonable reach for the well funded individual, I'd probably go for a 1950X system with two 1080Ti GPUs - should give me 90-100 Mkeys/s now and XXXXX in the future. If you want better price/performance ratio now, at the expense of less future potential, replace the 1080Ti with 1050Ti.

But I limited myself only with 1151 socket as 2066 CPUs/MBs overload my budget and also I don't like AMD. The second step will be GPUs but it's a little later. What you say about https://ark.intel.com/ru/products/126686/Intel-Core-i7-8700-Processor-12M-Cache-up-to-4_60-GHz with MB https://www.msi.com/Motherboard/B250-KRAIT-GAMING.html ? I'm not very familiar with modern HW so maybe there are better options. Any more advices ? Thanks.

So you're from Russia - or so? ;-) Cannot speak for the mainboard - didn't even look it up. The CPU is ok, my guesstimate would be 5.5 Mkeys/s.

For everyone else to estimate speed:
A 4GHz Kaby Lake core does about 1 Mkeys/s
A GPU client gives you a 7x speedup compared to a CPU-only client. (Now - soon this may be 14x)
So let's say you have a quad-core Kaby Lake 4GHz and a GPU -> 28 Mkeys/s
It's only a rough estimate, but should help you to assess what to expect from your hardware.

Rico, what about 2 or evern 3 GPUs and how it depend on GPU speed (how it's better to have 1080ti compared to some medium GPUs? does it have sence) ?
Arulbero wrote already something about this topic in this thread (scroll back for "CPU limited", "GPU limited" situation). At the moment a 1080Ti maxes out with some 45 Mkeys/s a 1050Ti maxes out at some 37 Mkeys/s "maxes out" = GPU limited situation. The GPU can't deliver more. In this case - if your CPU is stronger - a 2nd GPU will help. Let's say you have a 14 core Haswell ~2GHz and two 1050Ti, then you will get around 70 - 74 Mkeys/s Theoretically, if you have a mainboard with two such Haswells and 4 x 1050Ti, you will get double that keyrate. Same with other GPU/CPU combinations. 7820X + 2 x 1080Ti gives you at the moment 85/86 Mkeys, because each 1080Ti maxes out at some 43 Mkeys/ with that CPU. I'm trying to find both time and funds to improve the generators ( https://lbc.cryptoguru.org/crowdfunding), but interest is low, so for the time being we have to cope with these CPU/GPU limitations.

Congrats! 0.54 BTC so about $4000 right now. I see your are estimating 40 to 135 days for the next one. Happy hunting!

Im trying to run LBC on my new 7820X:
$ ./LBC -x Will use 8 CPUs. Testing mode. Using page 0, turning off looping. Benchmark info not found - benchmarking... 'kardashev-skylake-avx512' not found/executable.
LBC just downloaded .blf file but not kardashev-skylake-avx512.
LBC version 1.195
Any suggestions what's wrong ?

Sure, 171110-beafd74c1e70cb254a6b3cfcc6e1f8d0.kardashev-skylake-avx512.bz2 was missing on the download server, because that would break all clients who do have a Skylake (sans the avx512) and still run a client < 1.195. I have uploaded the binary now, so it should run for you, and whoever does have a skylake and client < 1.195 might want to update now.

I don't really get the trophy page of the LBC site. I can't see what the private key is they found. So what is the private key of the last address they found. #54??

When I run LBC on 8 physical cores - I got 8+Mkey/s, temp 60C and everything is stable. When I run on 16 hyper-threading cores I got 10+Mkey/s, temp 72C and server reboots in few hours without any notes in log file. Why can it happen and is it possible to avoid ? Thanks.
I don't want this thread to become a heap of individual pseudo-interactive support. If you have problems with your LBC setup, or stability, or whatever that could require interactive support come to our Discord: https://discord.gg/AyEfZrYI will delete further utterances like "my speed is..." You can give that info on the Discord channel too, and I can use it and update https://lbc.cryptoguru.org/man/admin#references at some point.

I have an "old" computer with a i7-3930K CPU. Running LBC with the "--cpu 12" command gives me about 4.8MKeys/sec now. What kind of GPU would you recommend to speed things up and how much Mkeys/sec do you think I'll be able to get with it?
Would it be worth using an NVIDIA GTX 1080TI or won't this one be faster compared to, let's say a GTX 1050 ?
