Building Cheap Miners : My "Secret"

[michaelw911]

I prefer the Z400s myself (I only did two T5500s) -- as of now I have one Z400 running with six GPUs no problem. I verified what my friend did.

I hadn't posted that update yet -- but it's exciting. The Z400s are beasts. Rock solid stability... cheap RAM & CPUs, and run up to six GPUs.

Have you ever tried more than 6 GPU's?

No -- I have not.

hey all...
im fairly new at this, but I like it a lot..
I have a chance to pick up a couple of old servers for about 250$ total...

1. Dell Poweredge 2950 (2U Server)
 Dual (2x4) Quad core Intel E5410 Xeon processors (8 cores total)
 8GB DDR2 Ram (Max 64GB Ram)
 Dual 150GB SATA hard drives (system supports SAS or SATA drives)
and
2. Dell Poweredge R610 (1U Server)
Dual (2x4) Quad core Intel E5504 Xeon processors (8 cores total)
 8GB DDR3 Ram (Max 192GB)
 Dual 160GB SAS hard drives (system supports 2.5" SAS and 2.5" SATA drives)
 Dual Redundant Power supplies

my question, what kind of hash rate could I expect out of these two for say, monero or other cpu coin?
would it be worth it at the end of the day?
thanks

Anybody have hash rates on E7-2850 Xeon?

The journey continues -- seven more racks going in. I have electricians in right now adding the power I need... I have the equipment already to fill at least 5 of the new racks & start on the 6th rack.

What's your opinion on the state of card prices at the moment?  Just curious as to your outlook on them.

I've been doing a ton of electrical wiring myself.  I had to pull 200a service 500' away to the container I'm retrofitting as a server farm.  Fun stuff! :/ lol

I quit buying cards because there are zero deals. I did back-order a bunch in December for my new racks and they are trickling in.

Do you own or rent the warehouse space?

Edit - also, this has made me really interested in cpu mining with servers. What kind of returns would you expect from one of those servers doing 2,200 h/s? Also - how much power would one use, and how much is heat an issue, compared to, say, gpu rigs?

Where do you get the commercial shelves?

I get them from ULINE.com

[sundownz]

I have one of the DELL Servers rolling... getting ~2100 H/S out of the box first try.

Using ~675 watts or so.

[sundownz]

And also pretty awesome... 20.3 KH on Yescrypt from the Dell servers.

That is like $11 / Day right now on GlobalBoost coin... not bad at all.

This algo pumps it up to an 800-watt draw.

I used Cpuminer-Yescrypt & compiled on Ubuntu.

Also... 64 threads is the fastest. I tried a ton of different thread counts.

How much were these servers again?

[PharmEcis]

How much were these servers again?

 They WERE 700 to 900... They are now close to 1500 and even an 63xx CPU is going for a premium thanks to someone we know.  Heck, they are even being advertised as miners on Ebay now!

You can get broadwell chips with L4 cache. P6300 and P6200 both have the same 128MB L4 edram that others were talking about previously in this thread.

Note: there was a change with the edram/L4 in skylake. There are also skylake processors with iris pro, but I have no idea if it will work the same as the other chips.

That was totally not worth it for $249....

I had a source lined up for $100 chips (ES Xeons with P6300) but the God damn Chinese are worthless to me and lied about having them. Between this and my PUBG experience I am beginning to hate them.

If you think that is a good value then you'll love the the new AMD apu's that are based on Ryzen with VEGA graphics on die. Only $100 for the cheapest one (Quad core + 512 VEGA GPU cores, unlocked CPU and GPU core) , should do at least 500 H/s between the CPU and GPU. In the least it would be a better choice for a rig CPU than a celery that will never ROI itself.

Video card prices seem to have hit their peak and I'm seeing prices "slowly" slide just a bit, especially on ebay.  I'm hoping this recent bloodbath in prices has scared away a bunch of people so card prices can return to normal and I can fill all these empty PCIe slots...

Yah I saw that, Didn't want to pull the trigger even at $700 when I saw that they were putting the word miner in the title, you know they are fucking you on the price then.  Mining aside, I don't understand why these Opertons sell for so much.  Like they are almost selling for over retail price, its kind of odd.

get your racisit bullshit out of here. You know my grandfather fought in WWII. He hated certain people because they made him kill civilians. Those people would put their civilians in guard positions with sticks in their hands. My grandfathers CO said kill anyone with a weapon. After they looked at the bodies they realized they were holding sticks. He hates the people that would do that to their civilians.

What side did he fight for and in what theater?  I don't think Juggar meant that he hates every Chinese person.  From a business standpoint of buying bulk electronics, they can be very frustrating.

I think 500 H/S is wishful thinking.  The 8 MB cache will be a limiting factor and I doubt the onboard GPU will contribute much if any hashrate as it will drag down the cpu performance.
