    Compatibility issues with ram on x58 mobos?

    semajha Level 1

      Hey everyone, new to the forums and looking for some advice on choosing ram.  For the past 2 weeks, i've been doing some research for my pc build and have discovered that a lot of x58 mobos have compatibility issues with certain ram modules.  From my understanding, x58 mobos are very finicky about their memory, so it's best to use memory that is recommended by the manufacturers memory support list.  One big issue that i've seen is that some motherboards have trouble detecting memory in full slots. So if a person were to run 2 6b triple channel memory kit (total 12gb), their motherboard will only detect half of that.  So a few of my questions are.... Is anyone here running 12 gb or 24 gb memory with no issues?  If so, what motherboard and memory configuration do you have? Is it possible to run a 3x2 gb kit and 3x4 gb kit(total of 18) together or would it be better to stick with identical ram?

       

      Here's what I plan on building:


      Mobo: Gigabyte X58A-UD3R or Asus P6X58D-E (I really want the UD3R but after hearing so many issues with memory with that board, i've considered the asus one)

       

      CPU: Intel i7 930

       

      GPU: Nvidia GTX 470

       

      Memory: No clue anymore, but i've been looking at Gskill and Corsair.  3x4=12 gb kit or 6x2=12 gb kit?  I hear that 2 gb modules have more overclock headroom?

       

      PSU: Corsair Modular 750HX series... I think 750 should be enough, because I don't ever plan on running SLI but if it's not enough please suggest other wise.

       

      HD: 2 x Samsung Spinpoint F3 1tb... I would add an SSD but they're a bit pricey atm.

       

      Additional Cooling: Kingwin XT1264

       

      Case: Lian Li PC-8NWX Mid tower

       

      Please let me know what y'all think, Thank you.

          My ability to choose components hit the wall at RAM also. I posted on this forum, this is the thread http://forums.adobe.com/thread/695662?tstart=60. (hope that link works for you). I am using 6 sticks of Kingston Hyper X. KHX1600C9D3K3 (2 kits of 3 x 2GB sticks) on an Asus P6X58D Premium motherboard and all 12 GB are posting. I have not begun to over clock yet, still reading up. Hope to get to 1600Mhz. I couldn’t afford the 4GB sticks yet(24 GB total), plan to upgrade later and pass these on to my son.

           

          My take:

          Try to stick to the QVL

          Seriously consider 4 GB sticks

          Note: a lot of people are using Corsair Dominators and getting it done

          Be ready to go beyond specks to achieve the power editors need (at your own peril)

           

          PS I am very happy with my CPU cooler. Noctua seems to care about their name. Great packaging, instructions, quality, and even included a tube of thermal paste and a nifty screwdriver (Note: very large; see Rowby’s Build on this forum).

            The two mobo's you are looking at are the same I've been considering and I also have been looking at RAM sticks with the same level of confusion. I didn't know the GIGABYTE board was fussy about ram. Was highly touted on Tom's Hardware and I see 4 users on the CS5 benchmark are using that board. I have a similar build going with the exception of a CM 932 X case and a couple more HD's. Maybe one of the big hitters on this great forum will chime in with some advice?

              This has all been discussed extensively here, but here are some general remarks:

               

              1. PSU: Check here eXtreme Power Supply Calculator Pro v2.5 , get the Pro version, enter ALL your components, including burners, fans, USB and firewire devices, set your CPU load to 100%, capacitor aging to 30%, calculate and add 10 - 15% for safety. Check the required amperage on each rail for the PSU you consider.

               

              2. Case: Get a big tower, not a mid-size. Easier to assemble, better airflow and cabling, more expansion room.

               

              3. RAM: More is better than faster. First is amount of RAM, 24 is better than 12 GB, second is speed, DDR3-1866 or 1600 is better than 1333, third is timings and the lower the CAS the better.

                I have the Gigabyte X58A-UD3R with 12GB of RAM with the i7 930 and a GTX 470. I've had no problems with the RAM and no problems in general. This setup is a replacement for a dual Xeon Tyan server board that I was running. My new setup is WAY faster with Premiere and cost about a 1/3 as much. I am using 2 packs of OCZ Gold XTC 6GB DDR3-1600, cost a total of $300 with a rebate, I think you can get it now for even less.

                  The problem with the DDR3 ram and the X58 platform that you are seeing has to do with the Secondary timings or Sub timings as they are called that the boards detect based on the profiles loaded into the ram and the compatibility profiles the boards have listed in the bios. This is why you see many board manufacturers such as Asus update bios just for a memory compatibility change. The IC's on the ram decide what timings are detected by the board and also the latency for many timings boards don't show. These IC's also will decide what latency the sticks can handle for the primary timings and the secondary. The problem is the current bidding market with the short manufacturing cycles are causing Manufacturers to build less at a time and order parts more often. This is pushing component prices up in the bidding going on especially for IC's that are performing better than others. The Ram companies however are trying everything they can to keep prices down do to the economy. This means they are often changing IC's constantly especially for the lower end  IC's where price is the overall deciding factor. These IC's are normally your 1333 sticks at CL9. First off find a brand from the QVL that the vendor is testing. This means likely they are getting ram compatibility updates from the manufacturer and the different speeds should not make a difference much in compatibility even if the particular model is not on the supported list. Second thing is look for DDR3 1600 sticks with CL6 timings if they are 2GB sticks and CL9 for 4GB sticks. Likely these IC's are the better crop since they are able to handle better timings. The last thing when buying 2 kits is look at the S/N. Often the S/n tells you on the sticks if they were made in the same or close production run. This likely means they have the same IC's in both kits and will run together. The problem most people have is with this last one. If you have 2 sets of DDr3 1600 with 2 different IC's on each set, that often causes the problem you mention. One way to fix it though is disable the XMP profile and manually set all of the primary timings, trc, trfc, and command value. That will often fix this problem. If not 1 of the sets has to be replaced with one with a similar IC or a bios update has to be made to update the compatibility for the board with those modules. Like Harm has said in the past, if you are going to buy 6, try and find a Hex kit where you know the sticks are from the same production run. That is just a little background and why this problem is so prevalent when you check forums.

                    alot of issues are down to people not understanding how to correctly set the settings and voltages in the bios.

                     

                     

                    I am running Corsair dominator 24gb kit 1600mhz with no issues.

                      True but the XMP profiles are suppose to make it easier. Also this issue shows up often on the first boot when the ram is running at the default profile which is normally based on 1333 or 1066. DDR3 1600 running at that speed can handle the default 1.5V as well as the QPI handling the default 1.1V when it's at 4.8. So it's not due to a lack of understanding as much as you might think.

                        Thanks everyone for the inputs!  I've been kind of busy with school so I haven't been able to reply back soon enough.

                         

                        Richardrocks, thanks for sharing that info. I have considered 24 gb but right now those are ridiculously expensive.. I refuse to pay that much for ram.

                         

                        Jay Knobbe, yes the ud3r is a highly praised budget mobo but from my research, I have found that it is picky with ram.  If you search up ud3r mobo on hardforums.com, you'll find that there's a 20 page thread on people having memory issues and most are only running a 6gb configuration.

                         

                        Harm, thanks for those tips. The PSU calculator will be extremely handy!

                         

                        jkosmicki, good to hear from someone using a ud3r board. OCZ seems to be a good brand but I've read a lot about the gold series ram and it seems to have quality control issues.

                         

                        ECBowen, wow... I am enlightened.  Thanks for taking the time to explain all that, I now have a better understanding of the whole memory compatibility issue and why ram is so damn expensive now.

                            X58 boards take 1.65v ram.

                              I have limited money and need something that works...

                                I am confused about this.  There are ram kits for x58 listed as 1.5v.  I think even some of the manufacturer tested ram kits for my Gigabyte x58 UD3R board are 1.5v. (I will double check this later to be sure of my recollection).  Well, I have Mushkin Silverline 3x4gb set of ram waiting to be assembled into my new PC.  Hope I am not in trouble?

                                  1333=1.5v

                                  1600= 1.65v

                                    Ok that is good, I have the 1333 at 1.5v.  For some reason, selecting the ram has caused me the most stress so far in this build.  I will not be free of stress until the parts are assembled and the RAM is working fine for a few weeks, lol.

                                        Hey guys, I wanted to give ya'll an update on my build.  So far, my mobo has no trouble detecting 12gb of ram in full slots(2x 3x2gb), However, I am having a difficult time overclocking it to 1600mhz. I'm sure it has nothing to do with the ram itself but more on the memory controller or in my crap batch i7 930.  I'm using 2 sets of Cas 6 Mushkin Ridgebacks, which has recieved excellent reviews everywhere.  I know Mushkin doesn't sound quite as popular as Corsair or GSkill but apparently they have a very good reputation of making high quality products and have excellent customer service.

                                            Also - has ANYONE ELSE - with ANY brand/type of 3x4GB ram? I can find NO positive confirmations of this and am looking for my first!

                                             

                                            Please understand I am not interested in any other RAM configs - and whether or not they work as well.

                                             

                                            Thanks to all!

                                              Does any one currently have 24GB of Mushkin running OK?

                                                  Scott - what are you running and what are your system specs? You have this rig at functioning @ home?

                                                          What Scott means to say is we use predominantly Mushkin in every system. We have a direct relationship with them and their engineers which allows us to make sure the ram is compatible and working with the boards in 3 or 6 stick configurations. With the volatile ram market as it is, the IC's for the modules are constantly fluctuating which makes compatibility between Ram sticks and boards a serious pain. That is why it's normally best to get a Hex kit when you get 6 rather than 2 tri-kits. Mushkin is well aware of these issues and takes allot of QA and testing time to try and eliminate them at the production level. We order bulk orders so they have to as much as possible to ensure compatibility whether we have 3 or 6 in a system. That is a nice benefit you get with Mushkin that you may not get elsewhere.

                                                            No system specs - no confirmation. Just your word. As everywhere else in every other forum. But I'm supposed to listen to you why? Thanks for nothing.

                                                              Thanks for the kinder disposition ECBowen. While I appreciate what  you are saying - I was looking for someone to  confirm that they themselves own or have seen this rig operate flawlessly. Specifically with the Asus P6X58D as originally posted.

                                                               

                                                              A  lot of what "should" or "might" means nothing and I would think that  across the whole of the internet that I could find one confirmation  anywhere. So far not a one. My guess so far is the mobo can't handle it but I cannot verify this yet.

Had you simply said, "Yes, I have built multiple systems with 3x4gb(6x4gb) Mushkin chips in the P6X58D mobo" then my questioning would have ended 3-4 posts ago.

I can just tell you that the Mushkin ram is tested with Asus boards specifically at Mushkin and that is the primary board company they work with besides EVGA. I have direct experience with about every performance ram line Mushkin sells and every one is profiled correctly and works with every board I have tested with including Xeon boards thanks to our allot of testing and feedback between us. Mushkin is one of the few ram companies that does test ram in user configurations such as 3 and 6 stick configs versus just 1 stick which is useless anymore. That is the most information I can give. BTW I believe Mushkin uses that exact same model board for Asus testing but I would have to ask them since I forget the exact model.

All hardware/compatibility tests were passed with flying colours! :-D

                                                                            I updated the BIOS to the most current version successfully (from FA to FC).  Maybe things are going too smoothly, and I am in for trouble.  I admit to being over cautious, to the point of running a wire from the table and wrist strap to a cold water pipe, to bleed off any static, lol.

                                                                             

                                                                             

                                                                            Did you end up making any changes to the memory settings in your BIOS?  One thing I notice in my BIOS, even though the latency on the Mushkin memory is something like 9, 9, 9, 24 (don't have the exact latencies handy), in my BIOS the settings are something like 7, 7, 7, 21.  Not sure if these are just generic defaults in the BIOS and I should change them, or if the BIOS set these latencies based on some property of the memory.  I am not sure if I should leave the values as-is currently in the BIOS (at least for now), or set based on the values documented with the memory.

                                                                            • 37. Re: Compatibility issues with ram on x58 mobos?

                                                                              If you are seeing timings of 7-7-7-21 instead of 9-9-9-24 in the BIOS which is the timing at which the RAM you bought is rated for that means it probably is running at a lower DDR Data Rate... 1066 instead of 1333. If it were me, I would deselect SPD in the BIOS, manually set the DDR Rate to 1333 (which the RAM is rated for) by changing the memory multiplier option, then manually change the timing to 9-9-9-24. I am assuming you just want to run the RAM at its rated speeds and you do not intend to overclock the CPU.

                                                                              • 38. Re: Compatibility issues with ram on x58 mobos?
