Building a Pc for Crunching.

[Norton]

Ah i meant the e3-1240v2 @Knoxx29

The setup that @Knoxx29 is referring to will have 24 threads total. I would expect 10-12k ppd from that setup and at around 160w

I just need a confirmation from the seller about the Bios Version.

That setup plus the 2 Xeons that I already have will Rock

Yeah i know. When discussing it over PM I suggested him that build instead of going for another 2 Xeon e3 rigs since it should be cheaper

What i wanted is comparisons in PPD or PPD/W for lets say 2 xeon re3-1240v2 rigs vs one of these rigs. I expect actually both to consume the same ~160W (as you suggested) with the difference being he would need here only 1 PSU and HDD and the GPU is integrated on the board. Adding that I found some really cheap 2nd hand xeons on ebay for him i think it's a better investment but since I do not have experience with multi socket systems I wanted to double check with more experienced members.

Also since the multi socket board requires for PSU with 2 8pin EPS12V and those PSUs are normally expensive high wattage. Would it be okto get a cheap bronze psu like the Corsair CX430 and a molex to 8pin EPS12V cable for the 2nd EPS 12V connector? Finally in the manual there is PW2 connector that looks like a floppy disk power connector but i think the 12V and 5V are switched. Can anyone confirm this? It's 2am here so brain is not working 100% right now

Edit: Nvm I think it should be fine

An XFX TS series 550w has dual 8pin power connectors and is fairly inexpensive

Update.
Hi Guys.

i need help urgently.

I would like to buy this Motherboard: Tyan S7010 // Dual Sockel 1366 Serverboard + 2 CPU's L5640 6c/12t @ 2.26GHz 60W
can someone tell me if the board is compatible with those CPU's?

Cheers.

motherboard: http://www.tyan.com/product_SKU_spec.aspx?ProductType=MB&pid=633&SKU=600000023
processor : http://ark.intel.com/products/47926/Intel-Xeon-Processor-L5640-12M-Cache-2_26-GHz-5_86-GTs-Intel-QPI
both are 1366 socket, thats a old socket but still capablo of hard work loads, i really doubt about the power consumption, 66W ..mmm i think 96W because on heavy load
1366 bloomfield xeon's processors are power hungry ...

That is wrong because a cpu cannot consume more power than what is rated at for sustained period of time (excluding Turbo). The total power consumption will of course be higher than 120W because motherboard, hdd and ram also consume some power and there is the <100% efficiency of the power supply but i think that a 160W is a reasonable estimate because this:

Just a suggestion.......socket 1366.......dual chip........cheapish...........new..........loads available


http://www.ebay.co.uk/itm/New-HP-Z8...6-Sockets-576202-001-460838-002-/121556714145

Spoiler: Badger

 

[krusha03]

I found some relevant info. If cinebench is re-presentable to crunching it seems that the dual L5640 will offer almost double the performance for a bit more than double the power consumption for the same price as one E3-1240 system

Problem is that its in the US and when the EU customs gets involved it gets expensive

@krusha03 If that board is suitable i will happily hunt for EU options, i have also noticed the quantity of "blade" server boards available 2nd user, although not a conventional shape they often come with CPU s included, possibly another option to consider.

It should be compatible. I dont see the L5640 listed in the specs of the Z800 but should work as the 5600 series xeons are listed. I have seen only one blade server with L5640 for 400 euros but seeing as I have no idea how you can make use of it without the Blade chassis and servers like this are not my theritory I cannot recommend them

just throwing it out there as a possible solution/option. They can be bought cheap as they are often replaced "en masse". Chassis for me wouldnt be a problem as i would make a case for it anyway.


If efficiency is key then i think a 2nd user blade mobo/cpu combo could be a good way to get lots of threads.

Its not about making a case where it cast stand, but making an interface to it for power + kb/mouse + video or network such that it can be controlled.

That's a dutch website not a german one And i think prices in germany are cheaper

My mistake, for some reason I thought you were in Holland.

The cheapest that I have seen here is 500 euros for a HP PROLIANT DL380G6 with PSU, 2xL5640, 2xheatskinks and 4x2GB ram

My mistake, for some reason I thought you were in Holland.

I am @Knoxx29 is not

I am waiting for the seller to confirm what Bios version is installed on that Motherboard

Worst case you can pick up a cheap dual core chip to do a bios update for the board before installing the hex core ones

That's mean that I could even buy the motherboard if has old bios version?

Correct! You would have to consider the additional cost of having to buy another chip though.

You could borrow one, if you were in the US then I believe @t_ski would be able to help you out... shipping to your area from here probably isn't very reasonable though.

I am going tomorrow to a computer shop where I buy all my hardwares and ask what they can do.

I would like to buy it before is gone.

So 24 threads total and 160w 10-12k ppd, that means that the ppd of each processor will be around 5/6k each one?
