Looking for thoughts & pointers for my new system.
I’m researching the build of a new pc around my existing M-Audio 1010LT. Aside from that, I intend to spend around GBP 500 not including the monitor. I’ll want dual monitors. I’ll be using it for heavyweight image processing in Gimp as well as Ardour stuff.
I don’t mind which distro runs on it although I’m more familiar with Debian distros than any other.
Any thoughts on a good mobo/processor/case combo? Any existing preconfigured systems from Dell, Lenovo etc out there? I quite fancy a Shuttle just cos they seem small, quiet and cute but fear whether the 1010LT will fit.
I think your 500 pounds will be quite enough
I can’t really recommend any specific mainboard, but I would go with one with 4 PCI slots. Most mobos only have 1 or 2, but maybe you want to add some delta 1010LTs at some time. I use 2 for 16 channel recording and they work very well together (besides with jack2… ah well). Yoo can even hook up 4 or more Delta1010(LT)s.
There are some mobos with onboard graphics, but I’m not sure if it’s possible to use those with dual monitors. If you get the chance, go for intel graphic chips, they are fully supported in linux.
I use a ATI radeon HD 3450 which is pretty cheap and works well for dual monitor. The support is getting better, I just recently had some success with free 3D support but it’s still not usable in conjunction with realtime audio, so I have to turn the 3D support off.
Regarding the CPU I would go with the best
It’s an 4x 3,4 GHz CPU, man, I got the 4x2,5GHz and it rocks It’s a pretty good price for around 150 pounds, and it might get lower at some other shop. If you are concerned about power consumption, you might want to consider the 4x3,2 GHz version.
Distro: Use a 64bit version to use all the RAM. I use 4GB and it feels soo good
Thanks for the reco Benjamin. My only worry with power consumption on a powerful CPU is fan noise - I’d really like a quiet machine if possible. Are my fears justified?
about noise, you can definitely have a “powerful” CPU and a silent PC.
I have a Core 2 Duo 2 x 2,4 GHz which is plenty for my use, and I have a kinda huge zalman cooler+fan on top of it, which I keep at the minimal speed.
see for example this link:
When the cores are 100% active, I get about 45-47 deg. In summer, I may get 50 deg. but never above.
I have an Intel mobo (DG965SS or something like that) which has an onboard graphics. It can be extended for dual monitors thanks to an addon card (intel SVDO on PCI express which will provide an extra DVI port). I worked with this setup for a long time but I finally gave up on the intel IGP and replaced by a passively cooled GeForce 9500 GT on the PCI express slot. This was almost night and day in terms of performance And it was not at all conflicting with the audio performance. I believe the MOBO has 2 PCI slots, so you can definitely have 2 Delta’s.
I have stuffed all this in a Antec Sonata III case which is very nice for silent operations. And its PSU is very efficient.
My hard disks are SATA 2, 2.5’ laptop sized HDs. The HD I use for data is really fast on its own (non RAID configuration). An ‘hdparm -tT’ shows very good results (~ 77MB/s).
I chose 2.5’ HDs for their quiet operations and lower power needs.
The PC sits below my desk, on a cushioned board for extra vibration absorption. I don’t hear it at all, even at night when the whole house is silent. When I turn the PC on, I hear nothing. I have been very happy about the result from the start
I use the arctic cooling freezer 64 pro for my Amd Phenom 4x 2,5 GHz and it’s pretty quiet. It becomes audible under full load, but it’s still very decent, and there are better coolers than mine. I think the Phenom 955 with 4x3,2 GHz matches the TDP of mine, but I can’t say if it gets hotter or not.
The main sources of loudness are my harddrives, so thorgal’s option sounds very good. I have 2 SATA II 3,5" Western Digital in a Raid 1 (mirror). They are not too loud, but most of the time louder than the CPU fan.
Thorgal: The free radeon and radeonhd drivers just introduced 3D acceleration support for the ATI HD series and are therefore still unstable and cause problems with realtime audio, at least on my board. To my knowledge, there is no free 3D support for nvidia cards at all (http://xorg.freedesktop.org/wiki/nv), or am I wrong here?
But then again, 3D pretty much doesn’t matter for audio and image processing
Vtech, I did consider water cooling briefly but I don’t think I can be bothered with it. I, too, have concerns about 64 bit. I’m asking myself whether it’s really worth the trouble.
Benjamin, I’m sure you’re right about 3d not being too important but I do want to do the odd video edit (nothing too tough, though). It’s a shame there’s no simple solution yet for RT+3d. I do need a dual head so I can run 2 monitors, tho.
I thought about using SSD’s to keep the noise down but they remain too pricey at the moment. Looking at my ‘parts bin’ I have an unused Hitachi Deskstar 500GB drive which I couldn’t get working on my old mobo (iirc it was to do with jumpers not available on the drive to make it back compatible with SATA 1). Presumably any contemporary mobo like the ones you guys are describing will be ok.
Thorgar, the Antec Sonata III case seems perfect. It’s on the shopping list.
I use the proprietary driver, especially since it can use the VDPAU (h/w pure-video for linux or so). I sometimes watch some HD videos from this PC (rare since I use it only for audio but it happens). It’s really great to see the CPU load remaining at 1% while enjoying HD-MPEG4 videos
The NV driver (open-source) has reasonable performance (2D) but no 3D. I think the “Nouveau” project aims at providing the 3D capability to users who wish to stick to open-source. Check it out, it may actually be already there.
I am very happy with the closed-source driver, so I didn’t dig it further. Note that I don’t use an RT patched kernel. The vanilla performance is already outstanding on my system, but I suspect it’s because I use an RME HDSP card (I disabled on the onboard sound). The only app that craps xruns on my system is lmms (which I never use anyway :D) but it’s because they do some “illegal” stuff (according to the jackd doc) in the main process callback.
Thorgal, if you can watch HD vid full screen on your set up then I’m pretty sure it’s going to be good enough for me.
Anyone have any keyboard and monitor recos? I guess I should ask on a graphics forum about the monitors, but for the keyboard it’d be interesting to know if anyone has found nirvana. At the moment, I’m tempted by a full sized wired Apple keyboard - I’ve never come across anything better.
Keyboard: I have no preference here, I just use a Logitech EX110 (which I will switch to a fully wired one because of the use of 1.5V batteries). I just need a US layout kbd but I live in DK, so it is quite annoying even though the US layout is in “my fingers”.
Monitors ? I don’t know, if you do serious graphic work … I have two Samsung SyncMaster 226BW. Very decent for my needs. They only go up to 1680x1050@60Hz (vert. refresh). They provide DVI-D (so digital only) and VGA (no HDMI). From my nVidia card, I use both digital ports (I have a little converter HDMI to DVI-D) so I have nothing plugged to the VGA port (neither the nVIDIA, nor the onboard Intel). I could actually use a third screen via VGA, which I have around but I see no use for it.
Note that these screen monitors are not fancy (no extra connectivity - USB - S-Video - etc) but they do the job right. I use the nVIDIA in twin-view mode so I have a virtual screen of 3360x1050. I disabled Composite (you know these funny desktop effects … useless), which improves the HD playback performance (no image tearing).
Anyway, this PC can be ON for weeks, with jack2, ardour, rosegarden, some VSTis, no crash, no problems. Very stable. I use kernel 2.6.32 provided by sidux (not debian sid since I want the high freq timer). I used to build my own kernels but since I am no longer using the RT patch, the sidux kernel is good enough
Keyboard: Silicon Graphics - Light gray (originally shipped with Octane2). The best keyboard ever for me. I have a bunch of them from Ebay and use them everywhere. (but I know, my preference is weird )
Mouse: Logitech MX
Note about disks: I use RAID-0 on the workstation for maximum speed (2x SATA on one machine, 3x 15krpm SCSI320 on the other) and RAID-5 on the fileserver for safety (2x 4 drives, zillion fans (ok 12) ). Network is gigabit.
Silicon Graphics: no, you’re not weird. The first time I toyed with unix was Irix on an Indigo about 15 years ago. I got two of them repo from a burnt out biotech company. It remains the prettiest box I’ve ever owned. And yes, the keyboard was world class (wish I’d kept it when I junked the box). Means I’d need a mobo with a ps2 socket, I guess.
I’m now searching mobos and am somewhat bewildered by the choice
here is mine (a little bit “old” by nowadays standards but for my use, it’s great) :
Thanks thorgal. I can pick that up for £75; I can think of no reason to choose sthg more ‘contemporary’ but I’m sure there are.
Just a few comments based on my somewhat limited experience:
Re: ShuttleX – very nice units but, with their small enclosure, cooling could be an issue. I had repaired one recently with massive hard drive failure (I believe due to heat-failure). Further, they have very limited pci expansion.
Re: Monitors – I use a beautiful 22" Sun dual input CRT - X7149A which I picked up used for a song four years ago. Excellent graphics capability with resolutions to 2048x1536, dp 0.24. I can’t believe what they’re going for now used – in the $700 range!
A couple of points… I also use the propietary nividia drivers (mostly for the convenience of twinview, and I have used RT Kernel and gentoo-patched kernel without noticeable latency difference… (round trip I leave it around 4ms at whatever freq I am using, I can push it further but don’t really feel the need)… I’m using a Saffire Pro 1010 on ffado, but on my older Delta 1010 had approximately the same performance.
One thing I would highly recommend is looking into any of the current Phenom II processors… (I have a triple core 720 BE) The performance is fanstastic for ardour even at clock speeds and the temps stay very low… so fan speeds can be kept very low…
I use an older Scythe Ninja rev B (about 4 years old) in a push pull configuration with one fan on the case and one on the cooler… both at low speeds and my system is OC’d to 3.5 GHz under I haven’t seen it go over 45 degrees C at about 25 degrees ambience (gives more headroom on the DSP/audio thread but it rarely goes beyond 60% so I could probably lower back to stock speeds)… I get more noise from my 2 * Raid 0 arrays creating vibrations through th, which I plan to replace with single SSD’s when the prices drop some more… (in fact the 2 arrays is probably overkill anyway for a DAW system)
I also don’t recommend the Shuttle boxes for the reasons above, both PCI slot limitation but mainly heat… for price/performance I recommend Antec cases especially the Sonata range… (but don’t use the slot cooler… it performs better without it)…
As for monitors … last year I won a Compaq 1600*900 20" monitor… this was never going to be my choice until I used it… (I bought a second)… 16:9 ratio goes very well for ardour as you get room for everything… getting a second down the track is something to consider as you can have your mixer on one screen and main edit screen on the other without need for switching between virtual desktops… (will post pictures to the other conversation in the next couple of days)…
Thanks for your comments allank & booniesboy. It looks like I’m moving towards a Phenom II with an nvidia card (a quadro?) in an Antec Sonata case. As far as the monitor goes, I’m a keen photographer, so I’m going to splash out on a good monitor (probably a Dell 2410WFP) ; to sit next to my existing cheapy 4:3 V7 for dual screen.
Am still bewildered by the number of processors / mother boards out there.
Which Phenom II should I buy? Does a quad core make any sense?
And married to which mobo? I’d be pleased to see firewire and a ps/2 socket (for the vintage silicon graphics keyboard I’m going to pick up). And obviously it needs a couple of standard PCI slots to accommodate my 1010LT.
ok, this is how my A/V system is shaping up. I’m not a PC builder by nature and only do this kind of thing every few years. Each time it’s a real headache catching up with technology changes. I’d appreciate any comments; especially any howlers I may have committed in navigating all of this!

I’ve got some budget left over for a graphics card, keyboard & mouse
I read that the Phenom doesn’t benefit massively from DDR3 RAM so I’m sticking to cheaper DDR2. I’ll run my old graphics card before deciding on a new card as I don’t have any brain cells left to work out what else to do. I’ll also cannibalise the DVD reader from my old box.
so you’re going for a 3.5" HD ? I hope it is not too noisy
ah no, it is 2.5" but is it SATA2 ?
The HD is a 3.5 SATA 3 Gb/s 7200 rpm I have lying around in a parts box doing nothing. If it ends up being too noisy I’ll look at buying something else, maybe SSD
