I don’t know if the difficulty is different on the FX computer, but before I played with my OC (went from 4.8 to 4.9) I was getting 3500+primes per second …Can anyone explain that one to me?
O man I can’t wait to throw my 400 cores at this…just need to figure out how to setup a pool so these machines can all work on one block/one wallet.
How do you have 400 cores 0_0 what kind of server setup do you have?

I work an aviation company on the Fortune 10 list. I manage the training centers in multiple states. Each training system is some form of HP z400/420/800/820 running four or six core Xeon and the training laptops are Dell Precision M6800 running i7-4800MQ. I have a few other mates from my bf4 clan throwing their systems on too (most of them are 8 core AMD)…I have ~100 training systems at any given time. Most of the time they sit doing nothing…so I figured I would setup my own “custom” “burn-in test” to make sure they are stable LOL…too bad I cant get access to our Linux HPC cluster (drooling at the thought).
7 threads per quad core and 10 threads per six core = 80-85% utilization w/o any I/O waits (giggity)
*envious glare * 
So, do cores make the most difference when it comes to mining? Would a $299 8 core AMT vishera hit more PPS than a $550 6 core i7-4930K, in theory (assuming the AMD proc to be 16 logical cores)? (or heck, any 8 core vishera vs any intel cpu)?
In the mid-range, would the AMD FX-8350 or the Core i5-4570 (or 4670) or the Xeon e3-1220v3 be faster? (I’m hoping the Intel, tough to find a good micro-atx or mini-itx AMD mobo…)
edit: looks like there’s not a big difference between the fx-8350 and the i5-4570 except AMD uses almost double the power. So now to decide between i5-4570 or the Xeon E3-1225V3…

Hey guys! I started mining yesterday on my desktop. I cant believe I hadnt done this earlier.
I have: i5 3570k overclocked @ 4.2ghz running Windows 8.1.
Currently hitting between 3173-3569 primes/second. Good stuff!
Currently, I am trying to figure out what would be an acceptable cost for a primecoin FPGA miner device but it lasts to me some high values (for me:).
For almost sure it can be done on a FPGA but I just cant appreciate if this is deserving or better said how much the miners/peoples would like to pay for it for a given mining speed efficiency.
The average value for primes per sec I see it is ~1000 - 2000 resulting in ~1-2 coins/day while mining on a PC 64bit.
From my ‘beginner’ evaluation such device would last at ~700-800 $ , maybe more for a speed ~ x5 - x7 than above , considering current dificulty.
Keeping in mind low power consumption for FPGA and a gain in mining speed maybe this is would be ok ?
Thanks for comments.
Will be posting some information as soon as I get out of newbie status 
I am using a server that has not been put into production yet.
Its a HP with X5675’s in it. PPS is between 66,000 and 75,650 I think this is good… still learning but fun to play with.
I have 6 servers that I am running the miner on all pointing to 1 worker. Most are only getting around 5,000 pps, should I be using different workers or ports for each server or will it really matter?
Thanks

My FX 8320 is somewhat faster than my Xeon E3-1230 v2.

At $0.09 kwh the FX 8320 will cost me $18.00/month. When you stress the FX and overclock it it will exceed 125 watts. The power difference can add up.
Also notice that the FX is faster with twice the sieve size.
Other things to consider is that FX barely overclocked runs very hot (~70C). My moniter has reported higher, but not when I was watching. You will need to spend extra to get a better cooler, extra case fans, and a case that can support them. The AMD’s are easier to overclock unless you get one of the unlocked i7’s. Assuming you can control the heat.
I want to say the FX has a better price/performance ratio but with the extra power and heat will make the setup and comparision not so straightfoward.
The E3-1220 and E3-1225 don’t have hyperthreading, I wouldn’t bother with them. The Xeon E3 1230+ V3 start around $270 and have lower clockspeeds than the i7’s and some don’t even come with integrated graphics. I would really look at the unlocked i7’s instead of the xeons. The integrated graphics will save you from having to buy a graphics card and save you from the larger idle power consumption of a discrete graphics card.
As for the FX 8350 ($199) vs i5-4570 ($199) I think the 8350 would be faster, especially overclocked. But again, with the heat and power issues it would be a tough call.

Hello all,
I have been searching all over and had a question regarding the following Opteron CPU for xolomining. I have not had success finding information here or on the internet for the Opteron 8386 CPU.
Would anyone have any performance stats/indicators for the Opteron 8386? They are fairly cheap and therefore easy to set up a mini-farm of sorts.
Hello there,
1st post is a bit of a long one, but hey…
I’m fairly new to the mining business, but can comprehend certain technical aspects of it.
Of all the coins that I’ve managed to read about, XPM seems the most inline with my life philosophy. I’ve volunteered for BOINC in the past for different projects (AQUA, POEM, SETI, etc.).
I’ve managed to start mining experimentally on my i7-Q720 laptop, just for fun, with beeeeer, after reading through the last 20 pages of the main topic.
OK, now for my inquiry. Let’s presume I invest, say, 1000$ in a Intel Core i7-4930K machine. Going by the Hardware comparison table for Xolominer + anty.info’s Primecoin Mining Calculator, a 3.050 Chains/d machine would yield 1.29 USD/d.
This would imply a ROI of 775 days = 2.12 years.
I get that these are very rough estimates, but even for a ROI of one year, wouldn’t that be not-such-a-bright-idea investment, given the fact that difficulty is (almost) constantly on the rise?
Thank you!
Marko

Hello!
As far as I can understand, the Primes per Seconds now are not indicative the mining speed. Much more important is to know Chains per day parameter. Right?
Please tell me what value of Chains per day do you have with your FX 8320 (without or with overclock) and Xeon E3-1230 v2?
Thank you!
