Building a Pc for Crunching.

[RigRebel]

Personally,

I love my Seasonic X650 gold. It's rated at 60amps and actually pulls over 70amps in testing. It has a single rail, fully modular, lifetime warranty (I believe) and you can get them now for about $120.00
I got mine for @$225.00 3 years ago so that's a good deal lol.

Also, you should be looking at this site > http://www.hardwaresecrets.com/page/power
It's my number one site for PSU info.

Also Their article "The Anatomy of Switching Power Supplies" is AWESOME!!

Good luck

Knoxx, you can use reg memory. Just look for 3x 2gb triple channel sets.

Is that a eatx board?

I thinks so.

It's actually SSI EEB, but most of the standoffs will work in a E-ATX compatible case (i think 3-4 are gonna miss align which isnt a big deal)

If the board will take regular ram (non ECC) I would go with that since it can be used on your other rigs if you need it for some reason,

This is absolutely true. But the ECC ram is only like 7 euros a stick

Scored my board.......Supermicro LGA 1366 Xeon Motherboard - MBD-X8STi-B paid £ 30.00 ( the buy it now vendor wanted £ 39.00) 30 quid and free delivery
The Cpu is enroute Intel Xeon E 5620 paid £13.00 including delivery.

I am selling a Giga GA 880g UD3H and Athlon ii x4 630 as a combo and i think they will cover the £ 43.00. The board unlocks the L3 cache turning it in to a Phenom spec chip. It will be a good buy for someone, it has certainly served me well.


So.....I should be Xeoning (new word) by the weekend.. Wahey

if anyone (UK) wants a link to vendors please PM

Hi everybody.
I am build my last Cruncher Machine but unfortunately I have a big problem.
Both socket are working and both cpu are working (I have tested it)
But here it comes the problem, if I install just one cpu the pc work perfectly but after I install the second cpu and i turn on the pc the fans keep running at full load and it doesn't boot.

Does anyone has any idea how could I solve this problem?

Cheers.

@TRWOV mentions something page 1. Sorry on my phone.
He refers to Windows server o/s.

Did you populate / seat the RAM correctly? I mean like specified in the manual. I've had boards that needed RAM to be inserted closest as well as farthest from the CPU's. Just my 2 cents. As both CPU's and sockets are working as you said, the problem probably lies somewhere else. Are your BIOS settings correct? I've never experienced this problem but it may be just a simple setting that needs adjusting.

Are you using the E3-1240 V2 CPU'S on that board?
Maximum configuration for those chips is one CPU.

he is using : Intel CPU Xeon L5640

So the problem its somthing on the motherboard im pretty sure, maybe some bios configuration, or a damm jumper...

 

[Heaven7]

Thanks, @peche , those CPU's should definitely work with his MB. Probably some faulty "CPU Configuration" settings in the BIOS. Hope @Knoxx29 can figure it out. Man - look at your credits, there! Are you ready for 100K?

 

[peche]

dont know this goal to get 100K has been pretty hard....also im pretty sure that some CPU configuration may help @Knoxx29 i have found this... http://www.tyan.com/manuals/S7010_Manual_v1.1.pdf

Yes, the S7010 is a real nice board! If @Knoxx29 didn't already check the manual, he should take a look at those BIOS options. Best reset the CMOS (used boards may have incompatible settings), then try the usual troubleshooting (1 CPU, 1 RAM module, onboard VGA only, no expansion cards/peripherals, then try again with 2 CPU's. See if any RAM modules are faulty/unsupported). Check full EPS power is connected. Good luck!

im afraid that our good friend knoxx is already sleeping ...!

Looks like he is... It's 4:34am, after all. Probably isn't on vacation, poor guy Hope he can solve the problem!

im pretty sure that tomorow our great friend will come up with a final solution!

I don't get the dual socket motherboard to work with both processors but just with one
Last night was a nightmare, I went in bet at 3:30 am and didn't solve the problem.

Note: the dual socket motherboard is running but just with one cpu

 

[krusha03]

Hey knoxx did you try running the board with 1 cpu in either socket? To make sure that the both sockets are running working. Also what's the bios version, maybe update the bios to the newest available and reset it to default settings with one cpu and add the 2nd one. Both 8 pin eps 12v are plugged right?

 

[krusha03]

Edit I just read the previous post that you tried both cpus and sockets. Also as @Heaven7 try running each cpu with just 1 stick of ram. Namely 2 sticks that you are sure to be working by having them tested with 1 cpu first

So here is what I did:
cpu 1 tested on both socket and worked, cpu 2 tested on both socket and worked, the bios version that I have installed is 3.01, I downloaded the bios 3.02 and 3.03 but when I try to installed it says that it's not compatible

I did try 2 sticks Ram that works.

I think you need to flash it in dos. It's really simple you just need rufus. Check here how to do it

http://www.howtogeek.com/136987/how-to-create-a-bootable-dos-usb-drive/

Also i see v302 has this
- Microcode Update :
1. Nehalem-EP(D0)
2. Westmere-E(B1)

So it may be that you need 302 or 303 (install 303 as that is the newest) to have the board running in dual cpu mode

 

[Caring1]

It might be the placement of the ram that is preventing it from booting with both CPU's in place.
Peche posted a link to the manual, it might be of some help.

 

[FireFox]

I know what I will do, because when I try to install the bios and failed it says that the windows version is not compatible I will try to install another windows version.
