Project for carpc
I am from Portugal and I bought a Fiat Stilo this week.
I want start a carpc project and I need some help and tips.
First I want to start buying some hardware.
In mind I have something like this for PC:
1x4gb RAM DDR3 1600
Board AsRock H61M-VG3 (http://www.asrock.com/mb/Intel/H61M-VG3/)
CPU Intel i3 (3220 with HD2000 or 3240 with HD2500, I think this will be enought)
Hard drive, 60GB SSD
And for sound card I think in Asus Xonar D2X/XDT PCI-e (http://www.asus.com/Sound_Cards_and_...ers/Xonar_D2X/)
What you think think about this? I dont want a high end machine just fast and with nice sound.
I am using 2 GB ram , for one reason , when you go into hibernate , your ram contents get written to the harddisk, and when you wake the PC up those contents need to be read.
The less GB ram you have , the less needs to be written/read , wich ultimately speeds up the shutdown/wakeup process
Only the amount of memory actually being used needs to be written/read upon hibernate/resume. I use 4gig and it resumes pretty quick. SSD is the key.
The only reason the hiberfil.sys is close to the same size as the physical memory size is to avoid having to resize the file if memory consumption is high. The contents of this file are also compressed to allow faster reading.
As for the soundcard, I would try to avoid PCI card , as they wiggle loose during driving.
See if you can find a nice usb soundcard in your area.
Honestly, I wouldn't even invest in a USB sound card until you have at least attempted to use the onboard sound for your motherboard.
Onboard audio hardware is much improved and it's possible it will suit your needs without having to sink more money into the project or deal with the hassle of another physical piece connected to your PC, either USB or PCI.
So first is better to test the onboard soundcard before buy a pci card?
I Will put the PC near the amps so the cable Will be short. I think that Will have enought voltage for the amp. Can a onboard soundcard have the same quality has a 120€ radio? My last radio on My Fiat bravo was a pioneer 2120 e think.
ok , I cant argue with that :D
So if I use the onboard sound card I will have the same (or more) quality than my old radio (Pioneer 2280ub)? That radio was great in my old car (Fiat Bravo) and was enought quality for me, I just want something like that.
I will put the carpc on the back so the cables for the amp will be short, I think I dont will lose mutch quality, am I right?
For the touchscreen what you recomend for a cheaper price? I see this on ebay:
Different motherboards have different audio hardware, output different voltages, etc.
Can the onboard sound hardware be as good as your Pioneer aftermarket? It could, yes.
Will it? You don't know until you try.
Until you start procuring hardware and doing some bench testing, you're not going to know anything.
Another option is that a large number of computers have an optic output on them that can be sent to a DAC or other processor. A fiber optic cable won't carry any RF and you won't have Ground loop issues. These allow you to totally remove the CarPC from the audio path electrically. It is an option if you should so desire to go there.
I believe there are a few on here that have gone this route and the DAC can be controlled through USB by the computer for settings. If you are looking for sound quality this is your best path.
