Hello, now I'm going to make a mining pc with 2 opteron 8439(6 cores, 6mb cache l3, 3mb cache l2, 2.8ghz), what do you think, how much h/s it can mine, and what software and how much threads I need to use?
Is opterons k8 (2 cores, 2mb l2 cache) can be userful for mining? Can I use 2l cache for this? It's so cheap for me, electricity is 10$ for month.

Currently mining on an R710 I got for very cheap, doesn't seem to mine half bad with 2x X5670s. I removed almost all of the memory and drives, and played around with different power settings. I seem to have found a sweet spot. While not as efficient as say an RX 550 per Watt - it's still a server I plan to use in the near future, right now it's just down time.
If E5 v2 prices go down, it might make sense to find a cheap chassis to run them in such as an Open Compute node, or on a bare motherboard ripped out of a Lenovo C30.

Its mostly about cache, so with 6mb.. i don't expect huge performance, probably around 200-250h/s. Its 2mb per thread, so 6 threads. Use xmrig.
Hello, can monero miners use l2 cache? And what do you think about core 2 quad processors for mining? They have up to 12mb l2 cache, and l2 cache is much more faster then l3 cache.
They lack hardware acceleration for AES. You will just burn electricity with very poor results.
Opteron 4171 too, but it gives 260h/s in single cpu config. Better cached cpu must be better, and with my electricity cost 500-600h/s is quite good.
Lets just assume 600H/s (I doubt it). With the current difficulty, thats equals 0.004 XMR per day. Without free electricity, you will never make a profit with that.
I did not look up any numbers, but I have a feeling that L2 on these old CPUs is not that much faster than L3 on modern CPUs. It was the last level cache after all...
In the end it comes down to this: If you already have the CPU, you can simply try it out. If you don't have it yet, there are many options that are way better.

Interesting information : if we have a cpu with a lot of cache memory, then our hashrate is limited only by cpu powerfull for aes, but we can know it without cpu too, only need to look to geekbench 4 tesults, aes is there, how much mb/s we have in aes, same will be hashrate for 1 thread of miner.
So, as example, x5470 will take 500-600h/s in 4 threads, and we still have 4 mb of free l2 cache(if use xmr).
@Joel but that is why all of the "try our infrastructure free in the cloud with XYZ cloud credits" is a lucrative space for miners.
During past two weeks Monero network hashrate and difficulty has increased on ~20%.
And block reward will continue to decrease.
Roughly 86% of whole emission will be mined at April (see graph).
Good bye profitable monero mining on CPU. Fck you botnets.

This morning , I check with mycryptbuddy monero profitability calculator,
in 3 months , my E5 v1 CPU will cause me money ( no profit ) to mine xmr due to high power cost.
Only V3 or newer CPU need to apply for mining jobs. I'll start shutting down E5 v1 nodes in few months.
E5 v2 CPU are not cheap either, still hoping for sub $100 v2 CPU, then I would swap out v1 CPU
I would still have about 30 E5 v3 nodes , wonder how long v3 CPU remains profitable.
Switching to GPU mining for other coins.

didnt see results in first page for a quad e7-8890 v4 just for reference on xmrig getting about 3800 h/s at 80% cpu load just with standard settings..also tested a dual e5-2699 which did 1800 h/s 80% load
