Hi all,

My name is Carlos I and live in Irthlingborough, UK. As member of SETI.USA I was invited by Bryan to join your forum with regards on a few doubts I have concerning where to buy cheap refurbished hardware in the UK, like the 24 thread xeons. Can you guys support me on this?

Kind Regards,

Carlos

Hi Carlos. Welcome to the forum.

I don't live in the UK but sometimes browse the Ebay UK site to point out some systems. On Ebay, the systems which already have 2x 12 thread cpus, at least 24GB RAM, HDD and OS (system ready to go) usually go for top dollar, but if you're comfortable adding RAM, cpu, HDD and loading an OS, it's possible to buy a a basic system and the parts you need on other auctions or elsewhere and build a 24 thread system for a reasonable price. What's your comfort level on PC builds? budget?

I'm comfortable on building and tweaking computers. My budget is around £600 with monitor included.

A 24-thread system, what possibilities do we have here?

AMD-wise: A dual Socket G34 mobo with two real 12-core Opterons (Magny-Cours) or two 6-module Opterons (Interlagos or Warsaw).
Intel-wise: a single socket mobo with a 12-core Xeon, or a dual socket mobo with two 6-core Xeons.

6-core Xeons might be the easiest/cheapest way IMHO, but this bloke sells 12-core Magny-cours for a mere 18 quid

A G34 mobo from the Czech republic for $250/£175.23

Here's my doubt as an energy consultant. I think a new skylake machine is more efficient than a 24 thread old Xeon but I see a lot of my team mates buying the latter, which I think it's wrong in long term as well in productivity per watt usage.

Skylake Xeon means Socket 2011-3 and DDR4 RAM and, being meant for a Xeon, ECC registered RAM at that.
Your budget is fading fast that way -but in the long run you are right in productivity per watt usage.
Another problem is that there is as yet no Skylake Xeon 12-core, the newest 12-core Xeon is Broadwell-EP.

When you go i7-Exteme you can use normal DDR4 RAM, but are as yet limited to 8 cores at max -though a 10-core i7-6950X looms at the horizon.

I certainly wouldn't disagree with your assessment of the power requirements and credits/watt. However, the price of electricity in the US is much less than the UK so that is not as big a factor for us. Also, if you consider the price of the dual Xeon X5650 systems versus the newer Haswell generation Xeons, it pays for a lot of electricity.

As Scole mentioned, you can buy a machine that isn't totally configured and add memory, 2nd processor, OS, etc and it will probably be less expensive than one that is fully configured. Be advised that on the Dell T5500s adding a 2nd CPU isn't just buying the processor and sticking it on the MB. You will also need a CPU/memory/fan riser and they usually aren't inexpensive.

I'm not familiar with the HP Z600s. They may already have a 2nd CPU socket on their MB.

I don't have a credit-watt-time comparison between the skylakes and the dual 12 thread LGA 1366 xeon cpu systems many of us are running but my dual X5675 cpu system pulls 353 watts. There are only 8 threads max in the skylake cpus, but I imagine a dual 8 thead xeon skylake cpu system could crunch as much as a dual 12 thread X5675 system. How many watts would a dual 8 thread skylake xeon system pull? Compare that to the 353 watts and the upfront cost of each system to each which one is cheaper over a 2-5 year period.

@Carlos, since you spend a lot of time chasing primes, then you might want to read THIS article. It may or may not be applicable.

Bryan, I am aware of this skylake issue since last November before it went public. Motherboard manufactures already released a patch and some still have to do it.

If I go for prime hunt clearly the new chips are more efficient than the Xeon due to avx2.0 even if the former has more cores.
If I go for ecm clearly it's pure GHz I need as other BOINC projects.

U.K. eBay is the best place to buy these xeons?

You can certainly find any flavor of system or parts on Ebay but I'm not familiar with the terms if you buy an item that's in the US. Do import fees have to be paid? How much or %? The bargain hardware link you provided has a Z600 you can configure. Looks like one can be bought there for less than £600.

Welcome to the forum Carlos. Think we need to start charging all you SUSA boys an entrance fee :D
I believe a certain scoundrel from your team sent you this way looking at xeon servers. I've made a new thread for you in the hardware section . Have a look over here and we will see if we can point you to a suitable choice.

Carlos, any comments :lol: ???

Perhaps the driver thought he would never be stopped. Or that traffic officers do not watch The Simpsons. Or that Homer Simpson really does live in Milton Keynes.

Whichever way, it was not the best choice of fake picture. Not if you want to evade detection, anyway.

When an officer from the Thames Valley force stopped a driver recently, the picture on the licence he handed over was of Homer Simpson.

The name was H. Simpson, and the address was 28, Springfield Way, USA.

Thames Valley Police said in a tweet: "Earlier this week, PC Phillips stopped a car in Milton Keynes.
