RAID w/ RAM help

I was looking to utilize my mobo RAID feature for the RAM.  I have a K7N2G Delta, currently i have one stick of pc 3200 ddr ram made by samsung, i wanted to know if I need to purchase the same exact stick of RAM to get the raid to work or if i can have different manufacturers with the same specs.  I am pretty sure with RAID for hard drives it requires the same models and manufacturers for it to work, was wondering if the same thing was necessary for RAM.  Thanks in advance.

If you're talking about Dual Channel, it is recommanded to use the same brand, model and size for both memory module.
However, as for the HDD RAID setups, you can try to mix and match. Results are not guaranteed though...

  • Does adding RAM help solve iMovie4 jerky playback

    I have been reading threads about jerky playback in iMovie4 in large projects, after adding music from iTunes etc. My wife has a monster project and playback during editing has became very eratic. I have emptied cache, repaired the hard drive, repaired permissions etc. I have not tossed iMovie preferences. I have 23 gigs of space on the HD and a 250gig external FW HD that I bought after she started the project on the internal HD. I would like to know from you experts: 1. Would it help to move the project to the larger external HD? 2. Would adding RAM help (currently iMac G5 1.8mhz with 768 megs RAM)? 3. Is there any way to tell if the project will export to iDVD smoothly if it continues to look terrible in iMovie playback? I hate to go through a few hours of rendering for nothing. Thanks so much for your help. I always find good and useful info in discussions.

    Michael, there are some very useful applications that I highly recommend to keep your Mac running smoothly. As a defragmenter I use Allsoft's Disk Warrior that also has a very good directory repair feature. Check out also Drive Genius that has a host of useful features. Also get iMovie file fixers, invaluable tool that is free that will allow iMovie to import certain files in audio and photo formats that are greyed out and also has other features. I believe I got mine from Mr. Lennart Thelander in previous posts here. Cache Out is an excellent application to clear out cache files. I also advise you do a regular permission repair from Disk Utility in your Utilities folder that is on your Mac. These are basically my must have applications. As for copying your iMovie project to your external, just drag your entire project folder ( the blue one with the media and star folder(s) in it directly in the external hard drive. I find that iMovie is one application that requires a clean (defragmented) drive with ample space to spare. I defrag my drives if I trash files often from them, or if I notice erratic and jerky performance or slowness in response. I hope that some of my suggestions will help your in your editing.

  • Will additional RAM help with Illustrator crashing?

    I just started a new job for a company that didn't have a graphic designer so they had to buy my all new equipment. Nice right? Except when the tech guy gets me an iMac instead of what I requested: a Mac G5 with a Power PC processor. Anyways I have the iMac which is nice, but not so quick when it comes to running Adobe CS2 programs...Illustrator, InDesign and Photoshop to be specific. THUS causing me major problems, cause those are the programs I need to use. I've only worked with this computer for a little over a week and Illustrator is consistently crashing when I open a file in Photoshop. This is getting slightly annoying. Will maxing out the RAM help with this problem? I figure it's the fact that Rosetta has to run in the background to run my Adobe programs which is causing the slowness and crashing. I'm used to using a G5, I had one at my previous job and it was pretty nice. AHH! Can I fix it with 2gigs of RAM or will I have to wait for Adobe to release CS3? boo.

    There is being able to run, and there is waiting or not realizing the benefits CS2 + Tiger offer when working on large documents. With small files, under 4GB RAM is desirable, with large files, sometimes you want/need 8 or 12GB RAM.
    And running XP on iMac for those applications while they are still not optimized - but it depends on what your time is worth. Maybe they are waiting for Mac Pro and don't want to invest in G5 (a Quad G5 isn't going to be obsolete tomorrow).
    The lack of 2nd drive or external SATA or FW800 is... odd. Even a MBP can add an ExpressCard w/ 32-bit SATA or FW800.

  • Adding a RAID card to help speed up export (and other drive question) in Premiere Pro CC

    First of all, I have read Tweakers Page exporting section because that is where my primary concern is. First my questions, then background and my current and proposed configurations:
    Question 1: Will adding a hardware RAID controller, such as an LSI MegaRAID remove enough burden from the CPU managing parity on my software RAID 5 that the CPU will jump for joy and export faster?
    Question 2: If true to above, then compare thoughts on adding more smaller SSDs for either a one volume RAID 0 or smaller two volume RAID 0 to complement existing HDD RAID 5. That is, I'm thinking of buying four Samsung 850 Pro 128 GB SSDs to put in a four disk volume to handle everything (media/projects, media cache, previews, exports), or split it up into two volumes of two disks each and split the duties, or keep the four disk volume idea and put the previews & exports on my HDD RAID 5 array.
    The 850's are rated at SEQ read/write: 550/470 MB/s thus I could get around 2000/1500 MB/s read write in a four disk RAID 0 or 1/2 that if I split into two volumes to minimize volumes from reading/writing at the same time, if that really matters with these SSDs?
    The Tweaker's page made a few comments. One is splitting duties among different disks, rather than a large efficient RAID may actually slow things down. Since the SSDs are much faster than a single HDD, I'm thinking that is no longer accurate, thus I'm leaning toward the Four disk configuration putting OS & Programs on C drive, Media & Projects on D (HDD RAID 5), Pagefile & Media Cache on SSD (2-disk RAID 0) and Previews &Exports on 2nd SSD RAID 0 (or combine the two RAID 0's and their duties).
    Just trying to get a perspective here, since I haven't purchased anything yet. Any experience/stories, I would appreciate.
    My current drive configuration:
    My D drive is software RAID 5 consisting of four 1 TB Western Digital RE4 (RED) 7200 RPM HDDs with a CrystalDiskMark SEQ Read/Write of 339/252 MB/s.
    The C drive is SSD 500 GB (Samsung 840 (not Pro) and does 531/330 MB/s. My OS, Program Files and Page File are on C, and data/media files/project, etc all are on the RAID drive.
    Problem:
    Current setup allows for smooth editing, only the exporting seems slow, often taking between two and two and a half times the video length to export. Thus a 10 minute video takes 20-30 minutes to export. 15 minute video can take 30-40 minutes to export. The first 10% of the two-pass export takes under a minute (seems fast), but it gets slower where the final 10 or 20% can hang for many minutes like my system is running out of steam. So where is the waste?
    I have enabled hardware acceleration (did the GPU hack since my GPU isn't listed) and it may spike at 25% usage a few times and eat up 600 MB of VRAM (I have 2 GB of VRAM), otherwise it is idle the whole export. The CPU may spike at 50% but it doesn't seem overly busy either.
    Our timeline is simple with two video streams and two audio streams (a little music and mostly voice) with simple transitions (jump cuts or cross dissolves). We sometimes fast color correct, so that might use the GPU? Also, since we film in 1080 60P and export 1080 29.97 frames/sec, I think that is scaling and uses the GPU. I know without the GPU, it does take a lot longer. I have ruled out buying a faster GPU since it doesn't appear to be breaking a sweat. I just need to know if my system is bottlenecked at the hard drive level because I'm using software RAID and my disks are slow and will hardware RAID significantly reduce the CPU load so it can export faster.
    Our files are not huge in nature. Most our clips are several MBs each. Total project files are between 5 GBs and 10 GBs for each video with Windows Media File export being 500 MB to 1.2 GB on average. We shoot using Panasonic camcorders so the original files are AVCHD, I believe (.MTS files?).
    Considerations:
    1. I'm thinking of buying (and future proofing) an LSI Logic MegaRAID 9361-8i that is 12Gb/s SAS and SATA (because some current SSDs can exceed the 6Gb/s standard).
    2. I'm not replacing my current RAID 5 HDDs because not in my budget to upgrade to 6 or more large SSDs. These drives are more important to me for temporary storage because I remove the files once backed up. I don't mind a few inexpensive smaller SSDs if they can make a significant difference for editing and exporting.
    I can only guess my HDD RAID is slow but the CPU is burdened with parity. I would imagine running RAID 10 would not help much.
    My setup:
    my setup:
    CPU - i7-3930K CPU @4.5 GHz
    RAM - G.SKILL Ripjaws Z Series 32GB (4 x 8GB) DDR3 2133 @2000
    Motherboard - ASUS P9X79 WS LGA 2011
    GPU - Gigabyte GeForce GTX 660 OC 2GB (performed the compatibility list hack to enable hardware acceleration).
    C drive - 500 GB Samsung 840 SSD (Windows 7 Pro 64 bit and programs).
    D drive - four 1 TB WD RE4 Enterprise HDDs 7200 RPMs in software RAID 5

    ........software RAID 5 off the motherboard ??????......NOT a good idea, from what I have read here on this forum from experts like Harm Millard and others. They have mentioned a LARGE overhead on the CPU doing this....causing sub-par performance. RAID 0 off the motherboard will NOT do this, however.....RAID 0 would provide optimum speed, but, with the risk of total data loss if ANY drive fails. You may wish to reconfigure your RAID to be RAID 0...BUT...you would need to DILIGENTLY back up its entire volume onto perhaps a quality 4TB drive very frequently.
         A lot depends on the nature of your current and FUTURE codecs you plan to edit. You may not want to sink a lot of money into an older setup that may have trouble with more demanding future codecs. For now, in the 1080p realm, your rig should be OK....the read/write performance on your CURRENT RAID 5 setup is not great, and a definite drag on the performance. The rest of your components appear to be fine.....the Samsung SSD, though not ideal, is OK.....it's write speed is WAY lower than the Pro model,but, the drive is used mainly for reading operations. Since you have Windows 7 Pro, and NOT Windows 8.......you CAN put the entire windows page file onto the RAID 0 you might create.....this will take that frequent read/write load OFF the SSD. Read the "tweakers Page" to see how to best TUNE your machine. To use your current setup most efficiently, without investing much money, you would :a. create the RAID 0 off the motherboard, ( putting all media and project files on it )  b. install a quality 7200rpm 4TB HDD to serve as a BACKUP of the RAID array. Then, install a Crucial M550 256GB or larger SSD, ( close in performance to Samsung 850 Pro...much cheaper), to put all previews, cache , and media cache files on....AND to use as " global performance cache" for After Effects...if you use that program. Exporting can be done to ANOTHER Crucial M550 for best speed...or, just to the either the FIRST Crucial or, the 4TB drive. Your current GPU will accelerate exports on any video containing scaling and any GPU accelerated effects. Your CPU is STILL important in SERVING the data to and from the GPU AND for decoding and encoding non-GPU handled video....your high CPU clock speed helps performance there ! You may want to check out possibly overclocking your video card, using MSI Afterburner.or, similar free program. Increasing the "memory clock speed" can RAISE performance and cut export times on GPU effects loaded timelines,or, scaling operations. On my laptop, I export 25% faster doing this. With my NEW  i7 4700 HQ laptop, I export in the range of your CURRENT machine....about 2 to 3 times the length of the original video. PROPERLY SET UP...your desktop machine should BLOW THIS AWAY !!
        Visit the PPBM7 website and test your current setup to possibly identify current bottlenecks,or, performance issues. THEN, RE-TEST it again, after making improvements to your machine to see how it does. Be aware that new codecs are coming (H.265 and HEVC,etc.) which may demand more computer horsepower to edit, as they are even MORE compressed and engineered for "streaming" high quality at a lower bandwidth on the internet. The new Haswell E...with its quad-channel memory, 8 core option, large number of PCI gen. 3 lanes, goes farther in being prepared for 4K and more. Testing by Eric Bowen has shown the newer PPro versions provide MUCH better processing of 4K than older versions.

  • RAID 5 + RAM general slowdown

    Hi everyone
    I have a 2006 Mac Pro which was fitted with a RAID card last year and configured with 3 disks + 1 rebuild spare. The disks are 1TB 7200rpm SATA drives.
    Now even though Xbench gives me a good score for the drive (142 global, 227 sequentil, 104 random) Everytime I fill my 4GB of physical RAM up (not very long with the Adobe CS applications) the computer grinds to a halt, even my music cuts out and it doesn't even have time to beach ball. before writing to disk
    Is this likely something to do with the RAID card or should I be looking somewhere else?
    Thanks for any help or tips
    Robin

    4GB may be cutting it close and not really enough.
    1-2GB for system, 3.5GB for CS4, 2-8GB for handling files and system cache.
    Adobe really needs its own non-system primary scratch, there is more complex I/O with RAID5, and isolating boot + scratch + media is always a good idea.
    The Apple RAID card... not such a great piece of technology.
    You are probably seeing page outs at this point.

    More RAM, better storage strategy, pull the RAID card and selling it...
    Also, Apple only certifies using their Pro RAID card with their drives which have custom firmware. Saying "1TB SATA" tells me/us nothing really. WD Black or RE3 or Enterprise while nice drives, are not supported (nor is Samsung), not sure if other retail drives (Seagate, Hitachi) work and if so how well if at all.

  • How much improvement would a RAID 0 setup help my speed?

    Hello so i do lots of HD rendering and im wondering how would a RAID0 help my render times because i thought the CPU does most of the work. anyway the drives would be 2 750 GB 7200 RPM's in RAID 0. what would be my speed increase if any?

    You should not oversimplify such considerations. The question really is, how you handle your footage and what your render settings are. This includes things like multiprocessing, naturally, but even for conventional renders it matters where and how the items are stored and what format they are in. Yes, a RAID may help, if you use lots of footage and that footage is stored on the drive, so reading the frames goes faster, but it may not necessarily help with storing the files, as only every few seconds or minutes a framer will be written. In reverse, a RAID could help, if you are outputting the same clip to different formats just by adding multiple output modules to the same render queue entry, but that one is rare. One other possible improvemnt would relate to the disk cahe, but it's really mostly only relevant for RAM previews. It also becomes a question, of whether AE actualyl fills it in the first place - if your project is not structured accordingly and AE thinks, it can calculate your effects faster than reading them from the cache, it will not use the disk cache for this stuff... It's really much more complicated, so you should evaluate your options based on the pointers I tried to give you.

  • RAID controller on G4; problems... is RAID dead? Help please!

    Hey.
    Here's the deal... Our graphics department has a MAC G4 (fully upgraded. newest patches, OS, etc.) that's got a 4 port SATA RAID controller. They use this with four 750GB hard drives as an external RAID (the OS is on a seperate, 65GB hard drive). The way it's set up, through Apple's OS, is we have the four 750GBs in pairs... those pairs are striped, and then the two sets of striped 750s are mirrored. This has worked just fine for a number of months, but we recently had a power surge, and now we're unable to mount "Monkey" (the name of the 1.4TB array).
    See the below screenshots for more clarification.
    http://www.amcdoors.com/lorenzo/raidsetup.JPG
    This shows the RAID card, and the four SATA cables coming out of it.
    http://www.amcdoors.com/lorenzo/leftside1.JPG
    As you can see in this and the below screenshots, this shows the 1.4TB Striped set as 'online', but the two below (the two 750GB hard drives) show up as "offline".
    http://www.amcdoors.com/lorenzo/leftside2.JPG
    this shows the actual drive i click on. same thing
    http://www.amcdoors.com/lorenzo/leftside3a.JPG
    If i click the entire array, you can see how it's set up (the Mirrored RAID set consisting of the two Striped RAID sets). The RAID sets (all 3 of them) are showing up as online, yet the drives are offline. No idea why. The drives are all powered, and are spinning, and plugged in.
    http://www.amcdoors.com/lorenzo/leftside3b.JPG
    when you click "Monkey Drive", nothing shows up in it. i don't remember if anything ever used to. if you click 'mount', nothing happens.
    http://www.amcdoors.com/lorenzo/leftside4.JPG
    http://www.amcdoors.com/lorenzo/leftside5.JPG
    this shows the exact same problem as the first RAID set.
    http://www.amcdoors.com/lorenzo/verifyRAIDset1.JPG
    If you try to Verify the RAID set, it shows that no repairs are necessary
    http://www.amcdoors.com/lorenzo/verifymonkey.JPG
    If you try to verify Monkey, you get a "Volume Needs Repair" error... but when you try to repair it, you get this:
    http://www.amcdoors.com/lorenzo/repairmonkey.JPG
    Really need help; this is a pretty critical problem. Someone that's familar with RAID solutions on MACs please help me out. We can't risk losing any data if at all possible.

    I wouldn't take the risk of buying RAM from an eBay vendor. You ask a very relevant question -- "is this a good piece of RAM or is it junk?" -- and with a no-name vendor, nobody is likely to be able to tell you.
    Many people can answer that question for a whole bunch of known, reputable vendors.
    Some good choices in the US include OtherWorld Computing and Small Dog Electronics; scan the discussions on this forum for many, many others.
    Macs can be touchy about RAM, and the few dollars you might save buying from an eBay vendor simply aren't worth the risk.
    Buy from a reputable, known vendor who will stand behind their product and offer a warranty.

  • RAID 1 failed, help!

    Currently using an 875P NEO-FISR and have the ICH5R raid controller set to RAID 1 (mirroring) with 2 Western Digital SATA drives, both exactly the same model number, size, etc. Had a power outage last night and when the power came back up i was unable to boot into windows. The POST revealed that Disk0 was corrupted but Disk1 is fine. When i browsed the RAID config menu it gave me the option to setup or break the RAID but with a warning that i might loose all my data   how can i get my system up and running? Please help.

    okay this isn't working :( went into the ICH5R's config utility and set to non-raid. Switched the SATA cables on the drives so that the good drive (Disk1) would show up as the primary. Went into the bios and setup the raid controller to be read as independant drives, set boot order to read from the good drive. Reboot and POST finds no bootable devices. Setup to read from the second drive (original Disk0) same deal. Went back and reconfigured the bios to read the raid controller as a raid controler (remember i reset it to read as seperate drives) then recreated the RAID1 with the (supposedly) known good drive as the new Disk0. Still no bootable devices found. As a whim i pulled both drives from the machine and hooked them to my good working computer and ran western digitals scan utility, both drives check out fine. help :(

  • Running Windows XP on my Mac. Would more RAM help?

    Unfortunately I need to run XP on my Mac and Im using a parallel, VMware fusion.
    However most of the time my Mac crashes or, if doesn't crash, it works VERY slow.
    I was thinking to buy more RAM (I have 2GB), would that help?
    Thanks
    B

    It depends mostly upon how much RAM you have allocated to your VM and the amount of RAM the VM software requires. Only one VM application should be used, either Parallels or VM Fusion. Trying to use both will require too much RAM for what you have installed in your computer. It's also critical that you have the most recent version of OS X required by the version of Parallels or VM Fusion that you have installed.
    The VM software can require over 1 GB of RAM when running the installed VM assuming you have allocated the minimal RAM needed for the version of Windows you are using. So a system with 2 GBs of RAM is obviously stretching the RAM resource pretty thin. If your particular Mac supports more RAM, then it would be a good idea to install more.
    If your MacBook is a Core Duo model, then 2 GBs is the maximum you can install. If you have a Core2Duo model then 3 GBs would be the maximum based on the information you have provided regarding the version of OS X that's installed. Open System Profiler in your Utilities folder and look at the machine ID listed. If it's 1,1 then you have a Core Duo. If it's 2,1 then it's a Core2Duo.

  • 915P Combo No Raid option please help

    Hi everyone,

  • RAID Mirror failed - help interpreting error code?

    Hi all - I run the primary disk mirrored on my Dual 2.0 Xserver (10.4.7) using Apple's software RAID. No problems for two years, but found this am a warning on System Monitor, showing my RAID as degraded - one disk had dropped out of the set. All functions continued forward without interruption.
    Here's all the system log has to say:
    Aug 12 18:29:34 mail kernel[0]: AppleRAID::completeRAIDRequest - error 0xe00002ca detected for set "Xserver80G" (9477A440-E50F-11D9-B65B-000D939C5BEC), member E612F8B0-3082-4222-A9FE-B58D35CDA3B8, set byte offset = 907558912.

    The System Monitor shows no pre-failure warnings on the HD's themselves, and I'm assuming there was an error in the mirroring, and the RAID software gracefully dropped the offending volume.
    My questions are: Any help interpreting the error code so I can narrow down the likely cause, if any? any ideas what causes this kind of error? Is it likely to recurr?
    Any help much appreciated. I'll be rebuilding the set tomorrow after working hours.

    The RAID set got out of sync. You might see this from time to time if you use Apple's raid driver.
    Take a look at softraid.com for a better driver.

  • Mavericks uses upp all my ram help ?

    I have 8 GB of ram installed and mavericks seems to use it all up. The memory cache as per activity monitor seems to keep all the data in it until all RAM is used up and then makes free space. I know restarting my MacBook Pro would clear the memory, but I would like to know if there is an alternative? Can anyone please help.  I know my RAM is good and my the hard drive I have installed is an SSD. So this problem is really crippling the potential of my system. Thanks in advance for your help ..

    Maybe we need to see what you have on your system as there is nothing about the way Mavericks is handling your RAM. This is the way OS X's RAM allocation works now.
    OS X Mavericks will use all of the available RAM and dole out that available RAM to other applications, as needed.
    Maybe your issues are elsewhere.
    It would help us to help you if we could have some more technical info about your iMac.

  • RAID BATTERY CONDITIONING, HELPFUL INFO.

    Point of Information: It took my MPRO 6 hours and 30 minutes (exactly) to complete the battery conditioning process, from a status of completely charged. It may not take this long if, for example, your battery is partially discharged. I spoke with an Apple Product Specialist via telephone who advised that there is no documented time parameters with regard to the conditioning process. He did advise that cache size, as related to the individual drives is a correlative variable. The Product Specialist also advised that I could carry on all normal work tasks while the conditioning process was active. He did state that I might notice slightly inhibited overall system performance until the conditioning process was completed, and the related write caches were re-enabled. IT IS VERY IMPORTANT not to reboot or shutdown your system during this process. If you do, the conditioning process will start all over from the beginning. For some unknown reason, my MacPro insists on 2 cycles of the aforementioned conditioning process resulting in about 13 hours total time allocated. After the first conditioning cycle is complete (battery shows charged and not conditioning), I have to shut the MacPro down, wait a few minutes and start it again. At that point, after a few minutes, the RAID Utility enters into another conditioning cycle. If I don't intentionally allow for the second conditioning cycle, it will automatically enter into the second conditioning cycle the next time I start the computer resulting in write caches being disabled and a drop in system performance prohibitive to editing and post-production workflow processes in FCPro/Motion, etc...
    The entire conditioning process can be monitored in more detail (in conjunction with the Raid Utility) using the OS's System Profiler utility. Open the System Profiler utility and select the "Hardware RAID" option on the left. From the System Profiler, you can monitor whether the battery is charging or discharging. The following information is displayed in Syst. Profiler:
    Hardware RAID
    Battery Info:
    Firmware Revision: 1.0d19
    First Installed: 3/8/07 3:10 AM
    Last Date Conditioned: Unknown
    State: Working battery
    Fault: Normal battery operation
    Status:
    Charging: No
    Conditioning: Yes
    Connected: Yes
    Discharging: Yes
    Sufficient Charge: No
    Here you can see that my RAID syst. is conditioning the battery; is currently discharging the battery, and there is not a sufficient charge. It is important to note that the system profiler does not automatically update it's own status real-time, i.e., you must refresh (command + R) the window to get the latest status.

    I found that, at the end of the conditioning cycle, if I allow the battery to continue charging for 9 hours after system profiler and the raid utility indicate a full charge, the computer does not enter into a subsequent, charging cycle. Accordingly, I can only deduce that either:
    1. although both the system profiler and the raid utility indicated a full charge, the battery has not actually reached a full charge, and thus enters into a subsequent conditioning cycle upon the next restart / boot.
    2. The raid card battery is bad, or on the way out (not even a year old).
    Apple Product Specialists (APS) have been very helpful, overall, and have shipped me a new replacement battery. While there are no specific battery replacement instructions available to the public, the APS I spoke with excerpted replacement instructions from the Apple Technician training manual and emailed me these. I have these available if anybody needs them. I will be happy to email them to you as I don't think I can post them anywhere here. You can find an email address to reach me under my profile.
