Topic: AMD Ryzen hashrate? - page 19. (Read 85898 times)

I 'm thinking to buy new threadripper ryzen 16-core version with 32 threads for mining,
also I need new PC for personal use.
I watch lot of videos about new ryzen processors, seem they don't spend much energy especially this one I'm talking about.
Looking to mine alt coin with X11 chained hashing algorithm.
Can somebody tell me how profitable it is? Some estimates of profit?

Basically you are telling windows that it can use larger pages amounts of physical memory instead of virtual memory, at least that's my understanding of it. You need to assign "lock pages" privileges to the user account that will be mining. Follow the steps here and it should work --- https://technet.microsoft.com/en-us/library/ms190730(v=sql.105).aspx --- you may need to reboot afterwards and when you start the miner you will need to right click and run as administrator for the changes to take effect.

Hi man, Are you talking about  Virtual Memory? if not, how i enable large page files?

Just got one if my own.  OC'd to 3.7 GHz and getting 206 kh/s with m7m

My friend just got a Ryzen 1700 and haven't played with overclocking yet (using stock cooler, too).  I sent him a script and cpuminer-opt (forgot version - at least 3.6.x) and he was getting 161 kH/s for m7m and 145 kh/s with xevan.

For context, I have a 4770k OC'd to 4.3 GHz and get 108 kH/s m7m and 87 kh/s xevan.  It's an average of 63.5% faster than my CPU, and he didn't even OC.

Even at 400 hash you get a CPU that pays for itself within 6 months at current prices. Since you need a CPU to mine with your GPUs anyways why not get one that pays for itself, brings in a little profit after that and also has good resale value?

For those that have an 8 core Ryzen and have not been able to reach 600+ hashrate on XMR, you will need to enable large page files (requires Windows Pro). Once I did that I went from ~450-470 to 600-630 hashrate on my R7 1700X @ 4.0 ghz.  It's a nice boost in AEON too (the most profitable CPU coin right now).

Seriously? That type of hashrate will yield less than $1/day with electricity factored in.

Really no point imo...

Thought I'd contribute my experience mining with an 1600X:

Using xmr-stak-cpu mining Monero I get on average just over 400 H/s running 6 threads.

My 1600X is downclocked to 3.5 GHz @ 1.087 V (SVI2 TFN). CPU+SoC power draw reported as 64 W (SVI2 TFN).

Although I can get above 430 H/s overclocking to 3.9 GHz, it is not worth the extra power draw. 3.3 to 3.5 GHz is the most efficient for Ryzen chips.

Personally I am very impressed and happy with the results.

Ryzen new faster cpu is coming.

Best algo for amd ryzen 8 core now ? .

Plus the Ryzen 8 cores use two 8 mb L3 cache's and if data is swapped from one L3 to the other it slows things down quite a bit, so I appreciate the info because AMD has a tendency to run unusual cache architecture on some of their cpu's and the more test data that is out the better.

Example on my FX 8320 mining monero:

AMD FX 8320 at 4.4 GHz VERY unusual results! LOL

Running XMR-STAK-CPU: only max listed, after a few minutes it would settle on a slightly lower hash rate.
8 threads= 305 H/s
7 threads= 435 H/s
6 threads= 329 H/s
5 threads= 324 H/s
4 threads= 219 H/s
3 threads= 217 H/s
2 threads= 111 H/s
1 thread = 107 H/s

The 8 core FX cpu's have a 8MB L3 cache AND each module pair has 2MB of L2 cache so the cpu has a total of 16 MB of cache.

So you would think that 8 threads would be ideal for monero, its not because of the cpu module's and 4 threads are not the fastest but they are the only down a little from the max seen with 7 threads and run much cooler and use a bit less wattage.

So look at the results above, 1 thread is 107 H/s and then 2 threads only hash 4 H/s more, then a BIG jump in the hash rate running 3 threads, then another tiny jump running 4 and on and on until 7 threads.

So running 1 thread per module on a FX cpu is the most efficient thing to do.

Running XMR-STAK-CPU on only 1 thread per module and there still is unusual results.

EDIT: I just remembered that I had lowered the speed to 4.0 GH/z before I did the testing below so at 4.4 GH/z it would hash higher.

If I set the affinity to even numbered threads 0,2,4,6 it hashes at ~339 H/s.

If I change it to use threads 1,3,5,7 it hashes at ~385 H/s.

So testing and sharing data can help everyone even tho it may not interest everyone.

I don't know if anybody else are mining monero on a fx cpu but if they are what I have found will help them.

EDIT: My theory on why FX cpu's mining monero is fastest using one thread per module is because of that 2mb L2 cache per module is that cryptonyte is running in L1 and L2 and if you run more than one thread per module the two threads are forced to share the single L2 and then have to swap to L3 therefore there is almost no speed improvement.

I have a single E5 2695 V2 mining monero on a dual 2011 board, its been running for a week and a half with zero issues so I have not needed to shut it down to plug it into my kill-a-watt meter.

It does run cooler than the 2670 v1's I sold.

I won a bid on ebay for one and was outbid on the second one so thats why i'm running just one.

Of course I know it's an 8 core 16 thread cpu. I was using the specific terminology in the program so that others can observe, compare, and replicate it if they have a R7 CPU themselves.

 You DO realise that the R7 1700X is a *8 core* CPU, not a 16 core?

 Threads via hyperthreading are NOT additional cores, they are more about being able to split usage on a core to be able to do 2 low-utilization things at once on a core.


 A lot of software is MISidentifying the Ryzen 1700/1700X/1800X as 16 CORE cpus, because they mark the first time AMD has put Hyperthreading into a CPU.

Probably Monero (XMR), at least that is what I would probably do if I was looking to CPU mine regularly.

I'm not sure if I understood everything you posted, but I will try to test some of those options when I have some extra time. I haven't even tried any CPU mining since the early days of Bitcoin, so I'm not at all up to date on it.

So what is the best currency to ryzen now? and with what miner. thanks for those who want to explain.

what cpu's would you all recommend with the 2011v1 board. taking into consideration power draw, mb, core count

so is this still the best kinda options compared to using ryzen to mine with then?

Can you do some testing with cpuminer-opt? The following algos are suggested:

Cryptonight: cache bound, threads = L3 cache MB / 2 MB, so 8 threads on 1700x. Already understood,
excellent performer.

Deep: compute bound and heavilly optimized for AES and AVX2, Comparing performance with Intel on
a thread and clock basis will give an indication of how well AVX2 was implemented. Should be able to
load all threads.

Lyra2z330: I/O bound, large array too big for cache. With only a 2 channel memory controller it likely won't
compete with Intel E series. Performance will likely peak with fewer than N threads.

It would also be good to confirm thread order. On Intel default affininity assigns one thread to each physical core before
using HT. Someone suggested Ryzen assigns threads diffferently when threads less than number of virtual cores.
