Forum: The Classroom Topic: building a dv workstation started by: whiskey@throttle Posted by whiskey@throttle on Nov. 16 2001,06:16
Should this have gone in the geek forum? Anyway, here's what I'm putting together: (both HDDs are U/ATA) Interestingly, the best price I could put this together for (after scouring the net) is about or so. I know a guy selling it with this: ...for Ŭk, configured. So, that sounds a bit tempting seeing how I really want those programs and am too busy to build this thing. Okay, lazy. Question is, is the Tiger + Athlon combo worth it? Or would it be better to go with dual PIIIs? I know that's a heated debate waiting to happen, but I'm curious about legit compatibility problems. I'm not very hardware savvy, so I'm a bit ignorant on this one. If anyone has experience that could be of assistance, I'd really appreciate it if you spilled your beans here. Thinking about getting a DVD-Rom and swapping out that Asus card for a GeForce3 as well...maybe an Audigy instead of the Live...but then we're reaching "ramen-for-three-months" mode.
p.p.s. - if anyone has experience/knowledge in the dv systems realm, I'd love to hear from you. This message has been edited by whiskey@throttle on November 17, 2001 at 02:05 AM Posted by miNus on Nov. 16 2001,10:41
Well first of all, I hate you Second, I don't really see any huge conflicts of hardware there... there have been known a few things that the 760mp chipset doesn't like too much, like Netgear NICs. What about swapping that Asus card for a Radeon dual head with 32MB of ram? And I personally don't think it's worth going with an Audigy rather than a SBLive, but then again, I don't like creative anyway Ok, now to the IMPORTANT PART. If you're going with dual Athlons, DO NOT SKIMP ON THE COOLING! Make sure you go with a good heatsink/fan combo, or else you are setting yourself up for major problems. Another suggestion: don't buy MP's right now (I'm assuming you don't want to splurge and buy dual XP MP's?), but instead buy two 1gig durons, or 950mhz durons. Yes, they will work on that board (I've heard of quite a few people doing just that), and that way you can save some money, and use it until you can afford 2 1800+ MP's. Anyway... I hate you Posted by smart on Nov. 16 2001,10:57

We used ata/100 hard drives to capture video and we were still seeing dropped frames. That was a dual 800 with 1 gig ram. Best results we seen are with scsi drives. But, I havn't tried the newer drives of today. But we did see dropped frames with those drives of the first ata/100's. But either way let me know how it works now and I may save some money on the next system and get ata/100'sThis message has been edited by just_dave on November 17, 2001 at 07:04 AM Posted by Observer on Nov. 16 2001,12:03
I've been told that TDK's VeloCD burners have Plextor mechanisms. I haven't found any evidence either way.edit: Were those ATA100 drives 7200rpm? 7200 vs 5400 rpm makes a big difference when capturing video. ------------------ This message has been edited by Observer on November 17, 2001 at 09:42 AM Posted by blanalex on Nov. 16 2001,15:26

raid is awesome, however if you're going to be doing a LOT of dv work, keep the raid array separate from your system; i partitioned 60 gb of raid 0 into two parts for system and files and it works just fine and very fast, but for best performance its better to have the os on its own drive and have the array just for storage.
Posted by ASCIIMan on Nov. 16 2001,16:21
Important question for drive speed requirements:Are you going to be using this system for DV/miniDV/DVPro or for capturing analog uncompressed/at low compression ratios? For DV, the system will be fine. If you want to capture high data rate analog, it won't even start to cut it. OTOH, if you were interested in editing video at high data rates, you probably wouldn't be looking at 100GB drives... Posted by incubus on Nov. 16 2001,18:29

The drives we used were the first ones out. Maybe it was just our card the pinacle dv500 or 5000 i cant remember. But we used 2 9 gig scsi 100000rpms it was nice and flew on video.But that was a couple years ago. Posted by DeadAnztac on Nov. 16 2001,20:26
I might suggest Dv.Now. My dad made up his own DV system, and I must say, it is damned awesome (He used 1.2 Ghz T-brid (not MP) and lot's off DDR RAM, with ATA/100 7,200 RPM drives and it works really really well. The DV card I suggested comes with some cool software (Premiere with it).< http://www.dazzle.com/products/dvnow.html > ------------------ Posted by whiskey@throttle on Nov. 16 2001,20:36

Well, I think I'm going to go with these cpus...just because I've seen 'em paired for pretty good prices with the Tyan mobo (and, that's what's included in the package deal I mentioned). I see your point though. I guess as long as it does the job proper I don't mind spending the money now and not upgrading later, you know?

I'll have to check up on that.

Okay...But I hear the XP isn't approved by AMD to work in dual. I'm not sure, though... Oh, and Just_Dave:
quote: I was talking with some people about this and got to thinking...were you running win98? That setup shouldn't be dropping frames at all. Perhaps you had an irq conflict...some sort of config issue. My friend here is mentioning that if it was win98, it may have something to do with acpi being partially manual as opposed to entirely auto in win2k pro.

quote: Let me first correct one little thing up top. That being done. Most of the time when someone says they are going to run a raid its a superbadass scsi card that acts as a mini-cpu for disk accessing. Its usually very expensive and a pain in the ass to setup, BUT once done you can have either super high speed data access, quintuple data redundancy or somewhere in between. Some of the new mobos come with it on the board and I have had only limited performance gain over straight ata with it. If your mother board comes with it good, if not, dont let that be a deciding factor. For the average person, including you, you dont need hardware raid. A. Because your only using 2 drives. If you wanted to run say 25 drives (no you cannot hot-glue more connectors on an IDE cable) or wanted scsi then it may intrest you. Next question. What os are you going to run? And the last part. Now if your gonna be running something besides windows Im sure one of the local j00n1x ninjas around here can help setup you up. If anyone is inclined to setup a hardware raid might I recommend Mylex as your brand of choice. (24 hour tech support and they will replace a defective card in 2 business days.)

quote: Now that I think about it, it was the 500 realtime board by Pinniacle (sp?) but we ran windows off a ata/100 and used the 2 9 gigs for capture and work. But with the phillips mpeg chips that were on that board.. 30 minutes ends up to be about 3 gigs.. if I remember right but I was working on that a couple years ago when the 800's made their debut. The dv500 if I remember right had an onboard controller for a scsi drive. When I went through a crash course video school we had a Mac running AVID with a 200 gig scsi raid. That was a beast with two 21" monitors. But anywho..
quote: Come to think about it, I think it was win98, well crap that was the problem all along I feel totally stupid. Maybe I will call him up and see if he is still using that system.

the tiger beat a xeon on benchmarks plus some other intel dual mobos. it just rox beyond beliefEdit: oh yeah you dont have to use athlon MP's with the board all other athlons are capable of working with it but seeing as it was designed for MP's AMD are trying to get a reason for people to buy them and also make sure you use registered ram otherwise it wont work. ------------------ This message has been edited by Dark Knight Bob on November 18, 2001 at 07:08 AM Posted by semper on Nov. 17 2001,15:31

The more expensive "DV" cards are just IEEE-1394 cards together with some editing software. (some may have analog video I/O too). So, you may want to just get a cheapo commodity IEEE-1394 card, depending on what software you plan to use. (I'm currently building a DV system for myself, but it's all Linux based. I've written a driver for one kind of IEEE-1394 card and I'm writing the editing software now =) BTW about dropping frames... The datarate of DV is 3.6 MB/sec, which is like 10\% of what a modern drive can do. If you are dropping frames then you are having interrupt or scheduling latency problems; try running stuff at real-time priority, or switch to Linux =) This message has been edited by CaptainEO on November 18, 2001 at 10:27 PM Posted by askheaves on Nov. 18 2001,03:44
My tiny thoughts, from never doing DV. Firstly, if cost is an issue with SCSI and it were all that important to speed, I'd get myself a small SCSI drive (enough for a 2+ hour video, or 18Gig) and do most of my storage on an IDE drive. Do my producing on SCSI, my storing on IDE. Also, I haven't seen a GeForce3 that is worth it's salt for analog video. Unfortuanetly, others are more suited. I'm an Intel and MS whore, so you know where I stand on that front. And, Plextor CD-Writers rule, but quality seems to have rubbed off on all their competition if you just need to do one-offs.I guess, if it's a purely DV machine, build it as such. You'll probably come off cheaper in per-performance if you make a DV machine and a workstation/gaming machine. Whenever you try to hybrid a special use computer with a general use computer, you end up spending more money and sacrificing one of the two. That's not the way they're designed.

Thanks or clearing that up, ASCIIman.
quote: Yeah, but I keep reading things like this:
quote: Then again, DKB may have a point:
quote: I don’t know. You guys know more about this than me. Still, I'm kinda sketchy about taking a chance. The last thing I want is this system hanging or otherwise fucking up. Perhaps the 1.2 MPs will be good for now, and I can just drop in two news chips when AMD releases a 2ghz+ version next year… (assuming I need it/have the $$$)
quote: Yeah, but ECC RAM costs more than double, IIRC. Approx. 贡 for 512mb DDR, and about 跋 for ECC. I'm not sure if I can afford that right now. Besides, do I really need it? I'm doing anything mission critical, running a file server, etc. Interestingly, though, in my research I came across this:
quote: Very interesting.
quote: Thanks for pointing that out. I’ve read about nightmares with the 75GXP, but not the 60. Still…I’m kinda worried now that you mention it. Anyone else have input on this? quote: Um, no. You are grossly mistaken. First of all, no respectable DV capture board is ฤ. I have a StudioDV (all rendering -> software) and it sucks major ass. I should mention that the StudioDV is about as cheap as they come. An RT board (like the Canopus Storm) completes a normally lengthy render in mere milliseconds: by the time you select a complex 3d transition, type in scrolling titling, or use a intricate after-effect, an RT card is ready for output. All hardware, no waiting. You can forget about this should you choose to use a “commodity” card, as you call it.
quote: Of course you do…how else are you going to know what it will look like on a television? Remember, your monitor is showing millions and millions of colors…an NTSC television is only what? 256? 1000? Also, your tv is running 640X800 – another thing to keep in mind. Don’t forget that while things may look in frame on your system monitor, they may be cropped differently on a tv screen.
quote: Yeah, I agree. But are the indented uses of this system (DV, graphics, music, games, office) really that far off? The DV is the primary usage, granted. But due to the fact that it's got major cpu horsepower, a nice amount of RAM, etc...it seems already qualified to do many other things as well. I mean, if your tractor looks like a Porsche and can do 90 down the highway, why not take it for a spin? The music and graphic applications I plan to use (Acid, Fruity Loops, Photoshop, Illustrator, etc) go hand in hand with with the DV thing. That's all part of the DV process. As for games, we’re just talking about the addition of a GeForce3 instead of that Asus 32mb dual head (I plan to only have one monitor anyway)…and I don’t plan to mess with analog video at all. So, I think it’ll be all right. Right? BTW, I see what you’re saying about SCSI, though. You have a good point. But I like the idea of having 100gb over 18.2, you know? Decisions, decisions...
Posted by miNus on Nov. 18 2001,21:15
A couple things:Any Socket A chip WILL WORK (as far as I have heard, as in, people DOING it) on the Tiger. Durons, Athlons, MP's (earlier MP's, palomino core, but marked at CPU speed), XP's, MP XP's (later MP's, palomino core but marked at PR speed). On to the ECC RAM issue. You _NEED_ ECC RAM. Although... I cannot recall if it's on the tiger or not, but on some DDR boards, you only need ECC if you plan on using the last two slots... You're better off going all ECC though, that way if you want to upgrade, you don't have to buy all new ram. I.E. if you have two sticks of ECC and you want to upgrade, put two more in... if you have two non ECC sticks and you want to upgrade, throw those away and buy more. But I'm pretty sure you just NEED ECC for the Tiger, period. Posted by ASCIIMan on Nov. 18 2001,23:09
Actually, you just need registered SDRAM, but good luck finding registered RAM that doesn't have an extra chip or two for ECC.

I'm not reading all that (above) shit!Last time I did DV editing was on a PII 300 w/ 392MB RAM. Beefy by the standards of the day. I think the only reason we didn't drop frames right and left was the SCSI disk. If I were to build a DV workstation today, I would seriously consider a G4 Cube. Then I would remember that its nice to buy things like food, and I'd go with an Intel setup w/ twin 10K RPM Ultra160 disks running striped (hardware RAID). This is the important part. Every god-damned memory benchmark I've seen on AMD setups has been absolutely horrible. Now, maybe my understanding of what goes on during video editing is flawed, but it seems to me that you want a lot of RAM, but more importantly, you want to use it quickly. I would even go so far as to suggest that you invest in one of those cards that lets you create giant virtual disks out of sticks of SDRAM. It's cheap, and would make extremely fast scratch space for editing, then commit to disk when you're done. Posted by miNus on Nov. 18 2001,23:49
quote: Oh yeah, *slaps forehead* that's what I meant the whole time. DDR SDRAM, though Posted by askheaves on Nov. 19 2001,04:21
quote: One problem you run into is that you need superbeef CPU to accomplish that. Simply, RAM read/writes are more closely monitored by the CPU, whereas disk hits are farmed off to DMA controllers and notify the CPU when they're done. Ramdisks went out a while ago for this reason. Posted by cr0bar on Nov. 19 2001,04:56
Still, I would think that the raw throughput would be higher, no? Also, it is very likely that these cards I'm thinking of (no URLs off-hand, though) emulate IDE or SCSI devices instead of true ramdisks.

ok heres the thing with the whole MP AMD thing.AMD wanted to get hold of the desktop market before they branched out into the dual processor market. a while back tyan who are the guys who suck AMD big fat cock made a business tiger prototype dual mobo. this was approx 2-3 times the price of the current commercial version. cos tyan have been best buddies with amd for so long they could take advantage of full support from amd and seeing as they are currently the only ones to be allowed to make a dual mobo for amd they made a goodun. AMD brought out the AMD MP which was updated from the thunderbird for more efficient use in a dual mobo. the xp i think has this tech as well as it use that palamino thingy. tyan and amd states u should only use MP's because thats what they were made for that ONE motherboard. of course because they're all socket a chips all socket a's will work in it. however now that theres the beefy 1900's out theres no reason why you cant take advantage of the increase in power. just dont tell amd you did it ------------------ |
