Recommended 2x Intel Xeon X5650, S 1366, Westmere Six Core Build parts?

Postby backbeatdeano » Sun May 01, 2011 3:07 pm

Hi peeps, i have been drooling over the 12 core Mac Pro recently, and seeing as i can't afford £4000, i have been considering an equivalent powered PC.

I'm slightly confused by the myriad of Intel code names, so i was just wondering if you could have a look at the proposed parts, and let me know if they're suitable/comparable with the build.

I'm after 12 cores, showing up in Sonar as 24 :-) Here's what i'm thinking...

2x Intel CPU Xeon X5650 Six Core Processor

BX80614X5650 - Intel Xeon X5650, S 1366, Westmere Six Core, 2.66GHz, 6.4GT/s QPI, 12MB Cache, 95W, Retail
---------------------------------------------
Mobo - Supermicro X8DTI Intel 5520 Dual 1366 Motherboard

I have chosen this board purely because the Scan Xeon workstation used one. Looking round the internet there doesn't seem to be anyone stocking this at the moment though, so if there are any other boards you recommend, please let me know!

For Ram, i am unsure as to weather i can use what i already have?? I am currently running this with my Dual quad core i7 setup. If this is not compatable, could someone suggest an alternative 6gb.
----------------------------------------------------------------
Corsair Memory XMS3 6GB DDR3 1600 Mhz CAS 9 Triple Channel Desktop

TR3X6G1600C9 - 6GB (3x2GB) Corsair XMS3, DDR3 PC3-12800 (1600) Non-ECC Unbuffered, CAS 9-9-9-24, 1.65V


Cheers guys...if you could let me know on this one that would be great. As i said, any comments or suggestions welcome!

Cheers now

Hi, can I ask? Why are 2 i7's not enough???

Are you scoring the War of the Worlds sequel?? Won the lottery, etc....

Hi,

1. Chipset - Intel offer two chipsets for socket 1366 Xeon DP CPU's: 5500 and 5520. The only difference between them is that the 5500 provides 20 PCIe 2.0 lanes off the IOH, while the 5520 provides 32. Both supplement this with a PCIe 1.1 x4 link.

2. Form factor - Supermicro only offer 5520 boards in the EEB/E-ATX form factor (305mm x 330mm). ATX boards are limited to 5500. Tyan, meanwhile, produce 5520 boards in the CEB form factor (305 x 267mm vs. the 305 x 244mm of ATX), as well as EEB/E-ATX.

3. Memory - Xeon DP CPU's support a maximum memory frequency of 1333MHz, and max voltage of 1.5V. Your 1600MHz memory operates at 1.65V. While the speed is not an issue per se - the board will simply default to 1333 - the voltage setting could be problematic, since manual memory voltage adjustment is not available in the bios.

In addition, you'd need at least twice the number of DIMM's you already have in order to operate in triple channel mode. Realistically speaking, six (or twelve) sticks of 1.5V, 1333MHz is what you'd want on this platform.

4. Power supply - All 5500/5520 boards technically require a PSU with 2 x EPS12V (8 pin) connectors.


You really need to decide on the memory capacity, PCIe bandwidth and form factor you require in order to make an informed choice.

ps - what do you mean by "dual quad core i7"?

Ah ha...i thought this would be trickier than i first imagined, thanks for the comments though :-)

My bad on the i7 front, i have a quad core which shows up in sonar as 8 Hyper Threaded cores, and am finding that the shear number of tracks and plugins i run is causing me to run out of cpu :-( I also play in a lot of synths by keyboard, so need to be operating at low latencys.

Don't forget your OS has to be able to see two physical CPUs - in the case of Win7 Pro and above

Why not get two 12 Core AMD Opterons and have a twenty four core monster... or two eight cores for a sweet sixteen

either way you might be upgrading your PSU as well

Yeah I tested and set that board up with the Quads originaly and I've not refreshed it yet, so I wouldn't look at it as being the optimum board for the purpose.

With the Extremes and now the Sandys being able to beat the dual quads in benching the hasn't been much call for the Xeons of late (as they are bloody expensive) but I've had enough interest that they really do need a look over. On my todo list currently as I've been out of the office a lot of late.
