In case if someone is looking to build a compact and powerful 8-core
ray tracing machine, the example below may be helpful.
Compact WS around X7DCA-L –
- Dual X5450 (8-cores / 3GHz 45nm Penryn ) or Dual X5440
- 12GB RAM
Components:
CPU (2 options)
• $1724 = 2 x $862 = Dual Intel Xeon Quad-Core X5450 3GHz 1333MHz
771pin 12MB CPU
http://www.ewiz.com/detail.php?p=XE-...a910e98fe7a214
• $1352 = 2 x $676 = Dual Intel Xeon Quad-Core E5440 2.83GHz 1333MHz
771pin 12MB CPU
http://www.ewiz.com/detail.php?p=XEO...a910e98fe7a214
$279 Motherboard X7DCA-L
http://www.atacom.com/program/atacom...Disp_item2.y=5
Note: I’ve purchased one of X7DCA-L boards from this store however I
do not know this store well to recommend, in my case it was totally
fine.
Memory 12GB 6 x KVR667D2D8P5/2G
$336 = $56 x 6 (6 x 2GB=12GB)
http://www.ewiz.com/detail.php?p=D22...a910e98fe7a214
Note: X7DCA-L is built around 5100 chipset and it uses DDR2 ECC/REG
memory (not FBDIMM)
$106 = $53 x 2 = Hard Disks 500GB RAID-0
2 x Seagate ST3250410AS 250GB SATA2 7200rpm 16MB NCQ Hard Drive
http://www.ewiz.com/detail.php?p=HD-...a910e98fe7a214
Computer Case (2 options):
• $99 “Troublesome” Small Size case (fits in carry on bag): If small
size of WS does matter then I would recommend SILVERSTONE SG03-S
however usage of this case will require some “metal work” to fit X7DCA-
L in. $99 SILVERSTONE SG03-S Silver Aluminum MicroATX Computer case.
This case is only for handy person. This case has only single 120mm
fan and one more 120mm fan would be recommended in case of X5450 CPUs.
http://www.newegg.com/Product/Produc...82E16811163082
OR
• $39 trouble free normal size case: $39 ENERMAX Chakra ECA3052B Black
ATX Mid Tower. One or couple more 120mm case fans would be recommended
if X5450 CPUs are installed and/or “video heater” card like
8800/9900GTX.
http://www.newegg.com/Product/Produc...82E16811124114
$65 Power Supply: RD550N-2SB-SL-BK ATX V2.2/SSI, EPS 12V 550W
http://www.newegg.com/Product/Produc...82E16817182151 Note:
Any EPS12V PSU 500W+ (24+8pin (4-pin is unnecessary)) should work fine
with listed configuration. If you are going to use power hungry video
card or/and battery of hard-disks then you need more powerful PSU and
normal size case.
$53 Video Card GeForce 8600GT. Note: The ray-tracing I run on this
machine has no use for GPU so any video card with decent 2D output was
fine with me.
http://www.newegg.com/Product/Produc...82E16814145146
$27 DVD Burner: Sony NEC Optiarc AD-7200S-0B. Note: X7DCA-L does not
support IDE connectors only SATA devices.
http://www.newegg.com/Product/Produc...82E16827118012
Total: $2257 (normal case and dual E5440)
$2689 (small case and dual X5450)
- Floppy drive may be required to install RAID-0 drivers (“F6” Windows
cumbersome procedure).
- The speed difference between X5450/E5440 is around 1.06 times (6%).
By the way, E5440 is around as fast as X5365 (65nm 3GHz 8-core) for
CPU intensive tasks and for memory intensive tasks E5440 is 20% faster
then X5365.
All X5450 CPU I’ve installed (12) exhibit strange/inconsistent
temperature readings however it has never gone above 48C (room <24C).
I did not see this behavior with E models (E5440 or E5450).
I’ve built two such machines in compact SILVERSTONE SG03-S case with
couple X5450 and 12GB RAM. There is some issue with back USB
(WindowsXP-64) but USB on MB works fine (probably chipset 5100 bug
since this strange behavior has been observed on both : X7DCA-L
machines).
Have fan.
