i386 vs amd64 .... x2 4400,3gb good enuf Core/Hybrid?having MD Playback issues

[cnadarajah]

Hey Guys,

first time poster,long time reader!!

I am in love with MCE, its amazing....so much in love that i just bought a crap load of motherboards,cpuz memory, audio cards, nics, cables, hdmi cables,speaker.... basically a ton of crap on ebay for 80% off hahaha.  bought a asus hdmi board for 30 bucks shipped!. 


anyways i have a core/hybrid on a 4400+ , 3gb dd2 1066  and a few local hard drives.(sata bus)

Im experiencing some performance issues.  a  remote MD start playing a movie fine, but it starts jitterring and cutting up maybe 2 minutes into it.



Issues could be i think
#networking issues, maybe go to gigabit on the internal network card on the next reinstall.?
#networking issues, cables could be crappy but i dont think so.
# could UI2 on the MD be causing this issue?
# is my Hardware good enuff on the Core/hyrbid?, i can bring it to 8gb and drop a phenom tri core or quad core in there if needed.
#considering my load does moving the core to a seperate box makes sense?will i see a performance increase?

Testing
im going to try playing a DVD locally 2nite on a md 2nite, if it works networking is prob my issue.



Im curious as to if this is cuz the HW is taxed... anyone else running similar hardware  supporting 4 MD`s and a few orbiters?

I could also split the core and the MD but i will only do so on the next reinstall if any of you Linux gurus think i should!!!

i should let you know that linux is not my first language.... ima a Cisco/Vmware/Systems IT guy so LinuxMCe is  fun ,but has a bloody hard learning curve!!...  lol at least this is a fun hobby!

The Cpu power needs to at the MD's not the core.
8gb will not help

Gigabit enet will help
Try changing to Ui2 masked if on alpha.

Processing/Video power is handled at the MD, not the Core.

What video and how much RAM does your MD have?

[cnadarajah]

Wel the Mds  Range from 3200+ to 5000+ am2 procs on DDR2 for the most part. 1 MD is a 939 3200+ ddr 333mhz with a nvidia pci xpress card with full blown ui2 which works great. ,but  i cant get good network playback on it... haven't tried local from disc yet but thats 2nite! to eliminate the network or ID the issue as the MD


I just wanted to verify with you guys... first thing is first i will test locally using a dvd 

. I got tons of ram and Cpuz and motherboards, so ill be adding alot to the wiki in the next few days!.


hey Talking about things that will help... anyone running N wireless to a MD?  i wonder in N is fast enough for network connectivity for LMCE Mds. full duplex wirless... aww man so sexi

[cnadarajah]

oh yeah and second ? is does the amd64 version  show any performance gain over the i386 build??

[colinjones]

the bandwidth of 'n' wireless isn't the issue.... question: how do you PXE boot a PC off wireless? More detail? OK, how does the wireless card know which SSID network to connect to and which WEP/WPA key to use to complete the association so that it has layer 2 access to your LMCE network? See the problem? No one has found a BIOS yet that actually allows you to preconfigure these values and then PXE boot off the wireless card, so that the card can connect to your wireless network without an OS present to configure these things. Limitation of wireless and BIOSs, nothing to do with LMCE. The only immediate way around this is using an external wireless bridge that can be self configured, then plug this bridge/AP into the ethernet port of your MD.


No, you will not see any noticable improvement with 64 over 32 bit.... too little of the workload benefits from 64 bit.... go with 32 bit as it is more stable.

Colin, you are the man.!


I see the issue, i was thinking the same thing.... i was going to try  to play with some wacky stuff with Vmware workstation...
connect wirelessly to the ssid and then just use networking  setting  on the workstation to emulate etho on the vm to use the  vm bridge
 which would be the wilress network

kinda the same way a network bridge would work xept the switch is virtual.

I know Directx9.0c works thru workstation.... i wonder how LMCE performs in a VM...
anybody have any hand on with LMCE and Vmware Workstation

boy i love hobbies that are fun and tedious... but so rewarding!

I don't really have a need to do this at the moment but...
Is there any reason why a second stage bootloader couldn't be built that has the wireless drivers and configuration and then forwards on to PXE boot sequence. GRUB already has the PXE bit and I think can have drivers.
The bootloader could then be loaded on cheap bootable media (ie: USB, CF or local disk).

There seems to be a lot of people asking for wireless MD's and IEEE 802.11n should have enough bandwith (at least on paper).

No reason at all, I looked into it at one point... there are lots of booters out there you can stick on floppy or USB, but kinda lost interest after a while (once I saw the forum post about kludging a disked MD, figured I would do it that way when I have the need)
