wmountney Posted December 18, 2007 Share Posted December 18, 2007 Hello, I just build a system using the ASUS P5E3 Deluxe motherboard, Intel QX9650 CPU, and two pairs of the Corsair CM3X1024-1333C9DHX modules for 4 GB total RAM. I am not overclocking anything, just running at the stock 1333 speed. It seems that the system is stable with either pair of the modules installed by themselves, but becomes unstable when all four modules are installed, resulting in random freezes. I noticed that although I purchased the modules at the same time from NewEgg, one pair of the modules are labeled as version 1.1, while the other pair is labeled as version 3.1. I have made sure I kept the matched pairs in the same colored banks, but I'm not sure whether this version number difference could be causing my problems, or if the board simply won't work with four of these modules at all. Alternatively, maybe there is some custom BIOS setting I can use that might allow it to work? I wouldn't want to have to lower the speed below 1333, however. I would appreciate any help that you could offer. Thanks, Bill Mountney Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted December 18, 2007 Corsair Employees Share Posted December 18, 2007 Can you tell me the Bios settings you have set for both CPU and memory and any performance settings that you may have set? Link to comment Share on other sites More sharing options...
wmountney Posted December 18, 2007 Author Share Posted December 18, 2007 I have everything set for auto, just the stock standard "Load Setup Defaults" settings. I've since done further testing and it is completely stable with two modules whether they are in the orange or black slots. The problems only begin when all four modules are installed.

Corsair Employees RAM GUY Posted December 19, 2007 Corsair Employees Share Posted December 19, 2007 Try setting the memory Voltage to 1.8 to 1.9 Volts and with 4 modules you might have to set the memory frequency at DDR1066. Link to comment Share on other sites More sharing options...
NOMAD555 Posted October 4, 2011 Share Posted October 4, 2011 Hi....I have a Asus P5E3 Deluxe WiFi-AP@n Edition same as the last member ive purchased the first ones when i got my BM they are CM3X1024-1333C9DHX @ 9-9-9-24 1.60V VER3.1 (TWIN3X2048-1333C9DHX),worked fine no prob.,and just a while back i got another 2 of the same but just the voltage changed to 1.5V VER3.1 and will not boot and i just noticed that one of the mods heat sinks was not on straight it has a gap more open then the others and at the top fin area are closer if you see it from the short side it looks like an upside down V,well think thats not the prob but just in case,i dont know if i should do like the other member you told to raise the voltage....please help me,i dont want to buy 4 new ones just to have 4 mods @ 4GB ...thanx Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted October 4, 2011 Corsair Employees Share Posted October 4, 2011 I am sorry but officially we do not support mixing sets, you are welcome to try it but it many cases it may not work properly or require you to manipulate the timing and or voltages. The heat spreader issue is not a factor and if you like you can request an RMA on that set and we can replace them Link to comment Share on other sites More sharing options...
gatormoe1 Posted October 5, 2011 Share Posted October 5, 2011 I never recommend using 4 sticks of ram in a dual or triple channel system. You do not get the benefits from it at all. Some systems won't even boot with 4 sticks (possibly your problem) and even if they do, again, you don't get benefits. You're better off getting two or three (depending on dual or triple channel memory) and just making up for the ram (if you really do need it) by increasing the size of your other sticks of ram.

What do you mean Gatormoe? 4 sticks in dual vs two sticks in dual. Where is the loss here? 4 sticks is an incresed load on the memory controller, but other than that, thats about it. Also this is the first that i have heard about some MB not booting with 4 sticks. If the MB has four slots then it is should boot with all slots filled. Can you tell me where you got your information? Link to comment Share on other sites More sharing options...
gatormoe1 Posted October 7, 2011 Share Posted October 7, 2011 Some motherboards have problems booting with 4 sticks of ram. Thats a fact. You lose performance when you use 4 sticks of ram, also a fact. Do you still benefit from the overall ram? Yes, but you don't get the full potential out of it.

peanutz94 Posted October 7, 2011 Share Posted October 7, 2011 Some motherboards have problems booting with 4 sticks of ram. Thats a fact. Maybe initially. But after the RAM is set up it should not matter. Even at that, those problems will be few and far between. You lose performance when you use 4 sticks of ram, also a fact. I have to disagree with you. I dont see how you could LOOSE performance from having 4 sticks or 6 sticks installed for that fact. You would still be running dual or triple channel at increased capacity. I would just like to know where you get your information. I have been around these forums for about a year and a half now and this would be the first time i've heard of this. If you go by this then a person would be limited to 8 or 12 gig or RAM max and should not use a 16 or 24 gig kit. Sorry i have to say this is wrong. Especially for the renderer or person doing video encoding or something similar that will use every bit of that 24 gig's Do you still benefit from the overall ram? Yes, but you don't get the full potential out of it. Again, i'm not really doubting you, just asking for some thing to back up what your saying. I understand that under certain circumstances performance does not scale linearly with the amount or frequency, but saying you LOOSE performance or dont benifit, isn't exactly the truth. I never recommend using 4 sticks of ram in a dual or triple channel system This seems to be your own personal opinion, and does not exactly reflect Corsairs position on this. Otherwise they would not sell/market 4 or 6 stick kits. Link to comment Share on other sites More sharing options...
gatormoe1 Posted October 7, 2011 Share Posted October 7, 2011 Dual channel is a technology that allows two sticks of ram to work together to receive and send data to your CPU. This means one action is being worked on by the 2 sticks of ram to make it faster. If you add 4 sticks of ram you are only increasing the load in the FSB and adding more calculations at one time for your CPU. If you want 4gb of ram you are going to get more performance, less latency with 2-2gb sticks of ram as opposed to 4-1gb sticks. It increases latency and reduces performance. They can market whatever they want to market but that doesn't mean it is beneficial for you. Think of it as a 4 lane highway, you take 2 lanes of traffic going in and out with cars in each lane, everything runs nice and fast because its set up for 2 lanes of traffic going each way (dual channel). Now, add two more lanes worth of traffic on those roads without adding the capability (more roads/more channels) and what happens? Your road can handle it but its going to take a lot more time to get all those cars through that highway. Link to comment Share on other sites More sharing options...
