    Areca 1882IX PCIE 3.0 Raid Controller - Need help

    dan_public2 Level 1

      I'm extremely frustrated!   I installed my new Areca Raid Card and can't get it to work!

       

      First was the issue of creating a driver disk.   After hassling with tools for two hours I finally found an old diskette drive and installed it on my system.  That finally worked.

       

      Then when I tried to install the driver, first it didn't seem to install.  I clicked Tab + F6 during boot-up and apparently that did nothing.  However it looked like it installed something.   Windows 7/64 blue-screened constantly until I restored it to an earlier version.   I went through this install to blue-screen process twice!  

       

      Anybody know any tricks to making this raid card work?   Remember that this PCIE V3.0, not 2.0.   Is this card ready for prime time? 

       

      If this thing won't work, are there any other quality controllers that WILL work?

       

      Thanks,

       

      Dan.

          Dan,

           

          I'm guessing your hassles are largely caused by the motherboard bios not being set just right. With hardware controller cards (all of them, not just Areca) your boot order is very important.

           

          If you will be setting up your boot drive or array on the Areca you must change the bios to boot from the controller, not from a motherboard SATA port (the default).

           

          Or, if you will be using a boot drive attached to one of the motherboard SATA ports, leave the controller card out of the PC until Win7 is installed and just add it afterwards. All the F6 special boot stuff is only required if you need to boot from the controller card.

           

          Finally, regarding future Areca bios (firmware) updates, they work fine using the web browser tool when I use Mozilla Firefox; they do not seem to work when I use Internet Expolorer.

           

          Good luck!

            Jim,

             

            My apologies for not being clear.  (I was totally PO'd by my experience with that board.)   Additional details:

             

            - The OS was installed and running on a Samsung 830 SSD. That will not change.  

             

            - The system was running fine prior to installation of this raid controller.

             

            -  During boot, it displays two error messages:

             

            F/W Detected: ** SDRAM Speed Not Enough** !!!!!

            No Bios Detected Disk found.  RAID Controller BIOS not installed!

             

            Then...

             

            Some volumes/raid controllers failed! Press <Tab> / <F6> to enter setup menu.

             

            Hitting <Tab> or <F6> or <Tab> + <F6> does nothing.  

             

            In Windows Device Manager,  "Raid Controller" appears as an unknown device. When the driver is installed from the freshly created floppy, the system blue screens.  It constantly blue screens until I restore it from a previous restore point.

             

            In the 196 page LONG-WINDED manual, there is NO information on the errors I'm seeing. None!  They prattle on about all the neat things you can do with the controller assuming the thing works. 

             

            How can I get this thing running? 

             

            Thanks,

             

            Dan.

              Dan,

               

              Since I live in a backward country, I'm still awaiting the availability of the PCIe-3.0 version. The consequence is that I have no experience with this specific card, but the message:

              F/W Detected: ** SDRAM Speed Not Enough** !!!!!

               

              is irregular enough to suspect that the cache RAM is not properly installed or is faulty. Can you check the module is properly seated? Otherwise I would contact Areca support. In general they respond quickly and are very helpful.

                Is the RAM stick in your Areca from Areca or 3rd party?

                  Dan,

                  I have this same card, and it installed without issue.  When the "detecting firmware" screen comes up during boot...if I hit <Tab>, then after it finishes loading the firmware, it brings me into the bios of the card.  It doesn't do this right away....it still takes about 30 seconds for the firmware to finish loading before it lets me into the bios.  I was able to setup a volume fairly easy in the bios tool, and once I had booted on into windows....I could add the volume there and it seems to be working well.  However, I'm still struggling with setting up the windows management tool. 

                   

                  If there is something I can do from a screenshot perspective...or answering questions...I'd glad to help. 

                   

                  I'm getting pretty impressive seqential read/write speeds with 10 SSD's attached.  3,600 MB and 3,800 MB/s, respectively.

                    Harm,

                     

                    I think that would be beautiful, "backward" country.   Given my issues, I'm not sure "backward" is appropriate.   I wonder if the PCIE V3.0 version is ready for prime time.

                     

                    The memory stick looked seated, but I reseated it anyway.   No change.

                     

                    I'll contact Areca about it.

                     

                    Thanks,

                      The ram stick is Areca - dead, stock standard.

                        My goal is to achieve your results.  One question - Do you have the PCIE V2.0 or V3.0 version? 

                         

                        Thanks,

                          3.0 version.  According to Wayne, mine was the first shipped. 

                           

                          I would post a screenshot of my disk benchmarks....but I've been getting just a grey box when I click 'Insert Image' for the last couple of weeks.  Don't know if it's just me or if it is impacting everyone. 

                           

                          You can see pictures of the card and benchmarks in this post on my build log thread.

                            Chris,

                             

                            Thanks.  Good info.

                             

                            I'm think that there are three possibilities:

                             

                            1) The board or memory module is defective.  I'll contact Areca support.

                             

                            2) The system bios is old and needs to be updated.   Updating the bios should be simple.  I'll try that.

                             

                            3) There is something inherently incompatible between my motherboard and the Areaca board.  My board is 30 months old, which shouldn't be an issue.  But I wonder.

                             

                            One option I'm considering is to upgrade my MOBO, CPU, and memory.   I want to that anyway in the next few months.  Given that your 1882ix V3.0 works perfectly on a newer MOBO, maybe now is the time.

                             

                            Thanks,

                             

                            Dan.

                              I hope Areca is responsive when you call them.  I would guess it would be unlikely to be #2, but #1 and #3 are possbilities.  Have you pulled the memory out to see if it looks damaged on the connection part of the PCB? 

                               

                              If your Board is 30 months old...it clearly isn't PCI-e 3.0.....so I would root for you to get a new board....even if that is not the culprit.  Take advantage of those fantastic new speeds!  Joe Biden would say that you are "puttin' it back in chains" by using this card in a PCI-e 2.0 socket.

                                Chains?  Hmmm...  Y'all don't think I should doin' that, do 'ya?!? :-)  I guess I'll be buyin' a new MOBO.

                                  Quick update.  I bought and installed a “P9X79 WS LGA 2011” MOBO , with 32GB of memory using an Intel Core I7/3930 CPU.   Good news - the system is VERY (blindingly?) fast!   Bad news - there is NO change with the Areca raid card.   None.   Same error.  

                                   

                                  And hitting <tab>, <F6>, or <tab> + <F6> does nothing.  

                                   

                                  I've contacted Benjamin Jiang with Areca who is listed as the USA-Areca tech support guy on this page: http://www.areca.com.tw/company/worldwideoffice.htm.  For reference, his email address is: benjamin.jiang@areca.com.tw.

                                   

                                  For now, I'd strongly suggest you not buy this raid card.   While it may simply be that I got a bad card and that Areca moves quickly to deal with this issue, there may be something more fundamental going on.  

                                   

                                  I'll keep you up to date with progress.

                                    Sorry to hear that.  You must have a bad card if you're getting the same error on two separate motherboards.  As mentioned previosly, my card installed without issue and has been running smoothly.  I've changed it from a Raid 0 to a Raid 5 and I'm getting amazing read/write speeds both ways. 

                                     

                                    Does the card show up in your device manager once you've booted into Windows?

                                      The card shows up, but none of the drives show up (there are 6 SAS drives attached to the card).  

                                       

                                      I've tried multiple things to get it to work, including disconnecting the drive cables.   Nothing changes.

                                        Status Update - The first round of Areca Tech Support was NOT good!

                                         

                                        Benjamin Jiang told me that I need to contact their distributor - Areca Direct - for tech support. 

                                         

                                        So I contacted Calvin Chen at Kaleidonet.  (Apparently some relationship to Areca Direct.)  

                                        Calvin was very couteous and helpful.  He sent me a new version of the card bios to install.   However, ALL of the Areca documentation for installing the Bios directed me to methods that don't work!

                                         

                                        Since I can't get access to McRaid, I can't use it that way.  It also mentions the nFlash utility in the \Firmware folder.  The only problem is that there is NO nFlash utility in the \Firmware folder!  

                                         

                                        I tried the CLI method on page 160 of the manual.   The Cli documentation is virtually unreadable, but I tried serveral options.  All failed.

                                         

                                        In frustration, I went to the Areca support link.  On a hunch, I downloaed "DosFlash".  Inside was "nflash"!!!   Lovely.

                                         

                                        I'm going to try "nflash".  Since I have to reboot my system, I'll end on this sour note - since everything else has failed with this product, I doubt if the nflash method will work.

                                          I'd give updating the firmware a 1 in 100 chance of solving the problem and would suggest you RMA the card. Their hardware support is glacially slow, but the did a fine job on only bad card I've ever had from Areca.

                                           

                                          While Areca controller cards may not seem like a budget card since they cost more than normal PCs, they are actually a pretty affordable card in the uber-performance catagory and cost less than ACCO solutions; I understand ACCO makes really excellent hardware and have extremely responsive support to go with it, but I consider them out of my price range.

                                            I'm not arguing that they aren't affordable.   Unfortunately mine doesn't work.  I looked for ACCO and could find nothing like that.

                                                Bill,

                                                 

                                                Good morning.   On the Areca "Contact Page" page (http://www.areca.com.tw/company/worldwideoffice.htm), it's separated into two areas - Areca Taiwan headquarters and USA Areca Tech Support.   Benjamin Jiang is listed as USA contact.  

                                                 

                                                When I contacted Benjamin, he asked who I bought the card from.   After writing back and telling him it was Areca Direct, he said that I needed to contact them because they provide support.   Apparently when you buy from an Areca distributor (like Areca Direct), the distributor provides support.

                                                 

                                                At this point, neither the hardware nor software work.   Two people from Areca Direct have contacted me with suggestions, but none have worked.

                                                 

                                                What's worse is that the software installation documentation is so confusing, that it's almost useless.   It assumes that the install will work peachy-keen and doesn't tell you what to do when the installation fails.   Most technical documentation is poor, but this stuff is extremely bad.  The "usage" documentation may be OK, but since the product doesn't work, I haven't gotten to that point yet.

                                                 

                                                Having written thousands of pages of technical documentation in the last  30+ years as a software developer, I have a decent idea of what's good  and bad.   These install docs are poor.

                                                 

                                                To be clear on one point - I want this to work.   I do NOT want to return it and buy another card.

                                                 

                                                Regards,

                                                 

                                                Dan.

                                                  I just got an email for Ray at Areca Direct requesting that I fill out a long-winded form re-asking for info already provided and/or info that's not available because the card is dead!   Now I'm becoming frustrated.

                                                    I'm concerned that Areca Direct is giving me the run-around.   If Areca Direct does not provide adequate support, I'm going to return the card and file a complaint against them with Areca Corporate.  I don't have time for this foolishness.

                                                     

                                                    Are there any other reputable US vendors that sells 1882IX cards?

                                                     

                                                    Thanks,

Just a quick wrapup.   As I mentioned above, it was a defective memory card.   The Areca UI is a bit confusing at first but it took only an hour or so to set up my Raid 0 and Raid 3 arrays.   The Raid 0 was ready in few seconds, but the Raid 3 took about 2.5 hours to go through it's configuration and formatting.

                                                                  About Areca Direct, initially there was a couple of rough spots, but they shifted gears quickly and I'm quite happy with their support.

                                                                    I'd be glad to rebuild mine into a Raid 3 array to keep that part comparable...since I don't have mine really placed into production mode yet.  I have 10 SSD's attached to mine, and there are so many forum members that talk about the poor write performance with SSD's, that I think it would be interesting and eye opening to run some comparative benchmarks. 

                                                                     

                                                                    I still get a black box when I click insert image though.  Is this just me or is anyone else getting it also?  Started a couple of months ago.  Before that, I could upload pictures fine.
