Looking at your signature, hehe...

Out for another year or so.

To make matters worse latest xeons have more than enough of L2 but guess what... some L3 is missing.

To be on topic, XEON... CACHE, FREQ'S OR CORES?, perfect answer is FREQ x CORES without HT.

OT: Most cpu-algos are not L2 limited, must Do Your Own Research.

Had a chance to test many different v3 xeons and compare randomx performance to specs, some observations:

-algo needs 256Kb L2 for every thread so hyperthreading is basically useless, disable it to save power or use cpu affinity to bind threads to 'real' cores.
-turbo bins, models with highest all core turbo are the best.
-tdp, on higher core count models after optimal tweaking you start hitting the tdp wall and throttling starts, negative vcore offset helps to a point where cpu crashes due to too low voltage.
-xeons run really cool, with a decent cooler heat is never a problem.
-exploiting 'xeon v3 turbo hack' can boost mining performance easily 20-30%.

What I forgot to try was some REALLY tight memory timings like with ryzens, v3 supports only DDR4-2133 and depending on how many memory sticks you have it runs on 1-4 way mode.

For example, looking at 2670 v3 I see it is a 12c/24t cpu with tdp of 120w, 2.3GHz base clock and turbo 3/3/3/3/3/3/3/4/5/6/8/8 meaning it will run on 2.6-3.1 GHz depending on how many threads you are using. 12 threads @2.6GHz will end up somewhere in 5k range.

Most likely you are limited also on your INTEL S2600CW2SR motherboard and the lack of tuning options and/ or possibility to use cheap ES/QS processors.

Do a search for 'List_of_Intel_Haswell-based_Xeon_microprocessors', really nice listing which clearly shows the most important specs for mining.

v3 and v4 Xeons are L2 limited on randomx no matter how much L3 they have.

2x 4627v3 ($100?) 20 threads @3GHz gives you 10k consuming 260w.

2x 2696v3 ($800?) 36 threads @2.8GHz gives you 18k consuming 290w.

To compare, L3 limited ryzen 3600 ($200) 12 threads @4.2GHz gives 7k consuming 100w.

Most Xeon 'mining' cpu's are L2 limited...

Also, I would like to see some test runs for lets say --nonces 500000

'16 KiB of L1 cache, 256 KiB of L2 cache and 2 MiB of L3 cache per mining thread'

I did mine from the start and have been following and testing since, must say I'm amazed about these latest versions. They are so fast even with old hardware windows & linux.

Looking at this endless sea of crypto scams it's really nice to see someone actually having a working product, keep up with the good work!

2599,50€

Speaking about heating during cold months, I have a glassed balcony where I could really use some heating. 16A (240V) breaker there, flat fee for electricity and fibre connection.

But I still can't justify myself why should I spend 369€ for a Vega instead of for example shorting next manipulated weekend pump (yet another ongoing btw). I just can't. No matter how hard I try.

I see people calling bottoms on every small pump saying it just can't go any lower, it has already retraced more than 78.6% or whatever fibonacci retracement. I'm an early adopter of crypto's and I can easily see them tanking even more though I wouldn't be very surprised if current levels hold.

Just an example, after solomining ETH for more than 6 months back in 2015/ 2016 and buying thousands more when the price was at $1 level this currrent $100 still looks like a very generous offer to me. Although I do understand people that bought in during Tether run might feel a bit shocked right now.

What I'm trying to say is that it's way too early to use past performance as a tool when speculating about crypto future, there simply isn't enough data available yet. One thing is sure, blockchain in some shape is going to survive.

I still dream of my balcony getting that miner heating but so far we are not even close. Currently market is priced at about 100 billions but the value is close to zero, that's the first thing that needs to change. All scammy exchanges, ICO's, tokens and 'stablecoins' need to disappear too. People need to understand that if poo is traded against shit and back on some shady Asian exchange the dollar volume is zero. Might be a long wait.

Disclaimer, I still hold some small amounts of XMR, LBC, XCN, RVN and BBR. All mined with AMD/ Nvidia rigs 2014-2018 

Pumping this ancient thread, 15 months later we are looking at that $3,000 barrier again.

GPU mining has gone down the toilet long time ago, only some hard core guys left.

Looking back that 15 months, what has fundamentally changed? Add one more year, 27 months, what has changed? Meh.

Moon boys always told you when that big FIAT crash comes all that money flows into crypto, right now looks like we are getting closer to that 'old money' crash, you guys still feel comfortable with your crypto investments?

Happy mining & holidays!

You guys need to think big.

If you want to get 1M ether, what is the cheapest way? Mining or buying?

If you want to be sure network will not be compromised? And you are loaded with cash after selling at the top?

Just some food for thought.

1x1080ti 2018 = 5x750ti 2014.

Cost to build a "rig", earnings, power consumption, everything. Well except those free pci-e slots you theoretically have today.

Still too much hope and hype here, is it just me or is BTC about to be programmed to get parabolic again?

BTW, there actually is https://shittomine.com/ nowadays. 

We are not there yet, this mining shit needs to dive more.

Hmmm, this reminds me of early 2016 and your comments about ETH.

You just can't pump and dump on CryptoBridge that's why volumes are so low (real).

Haha, skunkshit of 2018.

35M premine, circulating supply 45M. This will get listed for sure, but first we need some hype. Lets see if this still works. I bet it will.

I saw ROI in three weeks only three times (short periods) with Tahiti.

1) Buying new cards late in 2013 to mine LTC, sold them later and bought Nvidia.

2) Buying back second hand cards during ETH launch Aug 2015 to pool/ solomine ETH.

3) Selling Nvidia's and buying back even more Tahiti/ Hawaii early 2016 to solomine ETH.

Later they again did quite well mining XMR/ ZEC with modded straps.

I'm completely out of mining right now but i still like to lurk here, 7970 can STILL do quite well on some algos but you need to use right OS/ driver/ bios combo. If there was a contest for the fastest ROI Tahiti would still be on the podium although now it would take months to ROI.

Respect.  

 

Where?


When it has retraced exactly 61.8% on Bitfinex?

 

Cryptocurrency markets in a nutshell, all credit goes to tradingroomapp:

Currently AEX controls most of the monkeys, when you see that stash moving you can be pretty sure there's a pump incoming. It's not only about getting listed on exchanges, it's about the whole package. Listing, market making (=pumping, dumping,'volume').

Paying $7,000 to get listed on CryptoBridge in hopes XCN booms is serious waste of money, CB is a real decentralized exchange where market manipulating is just too hard. Much better use for 1 BTC would be starting to buying & selling your own orders on Freiexchange or better yet, trying to contact exchange owner and ask if they are willing to pump it if you pay 1 BTC. Currently 1 BTC market buy would take XCN to ~150 sats (+1000%), that would look good on coinmarketcap...

Yes, all this is OT, nothing to do with a good project like XCN, sorry for that. Just trying to help people understand how this market works, nothing to do with fundamentals, it's all about smoke and mirrors.

For XCN to pump it needs to be listed on some shady Russian/ Asian exchange. This could be it.

DO NOT pay for the listing, just let that whale make a deal and see where it goes.

HODL  

edit: Don't get me wrong, good projects like XCN will survive.

edit2: buy on frei, sell on china?

Just tested this latest windows wallet, old laptop with mobile connection synced in 20 minutes from scratch.
