Motherboard Teardown: DFI LanParty DK X48-T2RSB+

Hey there.

This is my motherboard 3 years ago. The motherboard was really great for overclocking, plus the catchy UV-reactive color slots. Until, suddenly the MOSFET burned when I turn on the computer.

Don’t really know why, I assume it might be from ESD, because I don’t use any chassis before. My board are just laying on my desk.

Even the MOSFET already burned, I tried to remove it from the board, and viola! it still works!

The Audio jack housing is broken, intentionally, because I want to see inside the connectors.

Ok, Here we go~

ICS 9LPRS918JKLF – FSB Controller/Clockgen(?) I don’t know the exact name for this chips…

 

SONY DSC

VIA VT6307 – Firewire IEEE1394 Controller. Honestly I never used the firewire peripherals… and ITE8718F Low-Pin Count (LPC IO). This chip controls much minor things, like Floppy Disk, Hardware Monitor, Fan Controller, PS/2 Keyboard and Mouse, UART, CIR, Parallel Port, etc…

 

SONY DSC

HCT164M by Texas Instrument : a simple logic circuit. Converts Serial to Parallel. Maybe for the 7-Segment Debug LED?

Old Jellybean Op-Amp! LM358 beneath the PCI-express slot…

 

 

Will post more motherboard later!
Wait for my MSI P67 Motherboard!

Configuring Cisco ODR Routing Protocol (CCNP Route)

On Demand Routing

odr1

 

ODR – Do you ever seen ODR words? you may notice it when you issue the command “show ip route”.

odr2

ODR – On Demand Routing. Most of Cisco router support it, but Packet tracer doesn’t have any ODR features.

Curios what kind of routing protocol is that? This is dead simple routing protocol. Even more simple than RIP.

ODR is Classless routing protocol (supports VLSM). ODR is considered as a third choice between Static Routing and Dynamic Routing. ODR itself doesn’t fully qualified as a Dynamic routing protocol.

NOTE: In the Cisco routing table, ODR-learned routes are marked with lowercase o character “o”. Don’t be confused with OSPF that using uppercase O.

NOTE : ODR only works in Hub and Spoke Topology. And CDP must be enabled on the router.

And, How it works?

ODR uses proprietary CDP (Cisco Discovery Protocol), as a transport to bring ODR’s information. and ODR uses very minimal router resource.

The spoke Router, is a stub router (spoke is always stub though), will gives the network information to the Hub. And then, every spoke router just using default route pointing to their hub, for communicate with other networks. The Hub router will read the CDP information/networks information from Spoke router, install it on the routing table, and use CDP source address as the next-hop IP to reach the spoke networks.

The Hub router, can redistribute ODR learned routes to another routing protocol such as RIP, EIGRP,OSPF and so on.

ODR does not have any metric calculation, However, the metric in routing table always shown as 1, and the default AD(Administrative Distance) is 160.

Commands for configuring ODR

In the Hub router, use router odr command under global configuration mode

In the spoke router, nothing required to configure. But, you can’t use any routing protocols in the spoke router in order to make ODR working.

Optional Commands to tweaks ODR:

– R(config-router)#timers basic

– R(config)#cdp timer

Overclocking a Locked Core i5 – 2400 (Sandy Bridge)

This is my current overclock,

Daily OC on 6 July 2014

Daily OC on 6 July 2014

for daily use, rock-stable, no BSOD’s

with extremely low voltage, so heat dissipation is very low.

My pc is almost dead silent; the 7200RPM Seagate Hard drive is the noisiest in the system. There are 4x 120mm fans, running at 650rpm (sometimes 0 RPM if the room temperature below than 23 degree celsius).

 

Ok, This is my first time posting in my own WordPress CMS and this is on my own home server. Wish me luck to continue maintain this server

Thanks for reading!
