theboyfold Posted September 22, 2010 Share Posted September 22, 2010 Hi all First post here, so please be nice :) I have a Gigabyte GA-X58A-UD3R mobo and have installed TR3X6G1333C9 RAM. However, the system doesn't always pick up all the RAM installed. I've also tried the 1600Mhz version of the RAM I've listed above. This is what I'd initially installed, but I had the same problems. Sometimes the system boots with 4Gb of RAM and sometimes 2Gb, and on good days all 6. Now I've never built my own system before (how many times have you heard that gem!) but I'm more than happy with what I'm doing. The Corsair site suggests the ram that I've installed as usable with the mobo. What should the settings on in the BIOS be set to? At the moment I'm using the Optimized Default settings. Any help will be gratefully received. Link to comment Share on other sites More sharing options...
Wired Posted September 22, 2010 Share Posted September 22, 2010 There's a sticky regarding missing memory. Aside from that, try enabling XMP. Link to comment Share on other sites More sharing options...

Any help will be gratefully received. I had the same problem with my motherboard. I updated my bios from their website and found Bios update "F6n" fixed the problem. Other RAM Manufactures are having the same problems it is just not a corsair issue. Link to comment Share on other sites More sharing options...
theboyfold Posted September 27, 2010 Author Share Posted September 27, 2010 Thanks pat5zero, I'll have a look at that update and let you know how I get on. Also where do I enable XMP? I can't find it anywhere in the BIOS, or is it somewhere else? Link to comment Share on other sites More sharing options...
theboyfold Posted September 27, 2010 Author Share Posted September 27, 2010 Having finally come across the list of supported RAM for the motherboard, am I wasting my time trying to get the RAM to work as it's not even listed? http://download.gigabyte.eu/FileList/Memory/mb_memory_ga-x58a-ud3r_v2.0.pdf Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted September 28, 2010 Corsair Employees Share Posted September 28, 2010 If you were having the same issue with two separate kits something else is most likely causing the issue. Go ahead and update to the latest bios from Gigabyte. If that still does not work test each memory slot individually or try reseating the CPU.

theboyfold Posted October 4, 2010 Author Share Posted October 4, 2010 I've updated to the latest BIOS and now everytime the system boots it sees 6gb of RAM, so that's good. What's not good is how unstable the system is! Almost everytime I start up Windows I will get a memory_management BSOD. Seems the RAM timings when set to Auto in the BIOS don't match the true timings of the RAM, so I'm going to set them manually to match the sticks and run some tests. Any advice is welcome!

theboyfold Posted October 4, 2010 Author Share Posted October 4, 2010 After reading up on the memory_management issue I've upped the voltage from 1.5v to 1.6v and it's no sustaining a IntelBurnTest, which is couldn't do at 1.5v Maybe that's part of the issue as well? I've been reading in a few places that the voltage needs to be lifted on these DIMMs Link to comment Share on other sites More sharing options...
theboyfold Posted October 4, 2010 Author Share Posted October 4, 2010 Now giving Memtest86 a go and have come across 39424 errors in the first 3 mins. I'll leave it running for a few hours and come back and see what's what. I might swap out the RAM that I have with the other RAM to see if I get the same issues. Being getting loads of BSOD all day long now, sometimes when it's just sat idle and I'm working on another machine :( Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted October 5, 2010 Corsair Employees Share Posted October 5, 2010 Let us know what happens with the other kit as it is possible it is a bad module. Link to comment Share on other sites More sharing options...
theboyfold Posted October 5, 2010 Author Share Posted October 5, 2010 Have run Memtest on all three modules (at least 5 passes) in the first slot and they have all passed. So I'm not sure what it is now. Any suggestions as to how I can test it within Windows? Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted October 6, 2010 Corsair Employees Share Posted October 6, 2010 Have you tested the individual memory slots? Link to comment Share on other sites More sharing options...
theboyfold Posted October 7, 2010 Author Share Posted October 7, 2010 Not one by one, that's something I'm planning on doing now. Can I use just one stick or all the sticks in all the slots?! Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted October 7, 2010 Corsair Employees Share Posted October 7, 2010 All of the white slots will work with only one module. Link to comment Share on other sites More sharing options...
theboyfold Posted October 7, 2010 Author Share Posted October 7, 2010 Running 1 or 2 sticks of CM3X2G1600C9 with XMP enabled I get no errors in Memtest. When I insert a 3rd stick I get loads of errors. This is the case with any combo of sticks. Now if I set the MoBo to run at fail safe defaults (excluding setting the correct clock speed for the CPU) I get no errors with 3 sticks in. FYI it sets the clock speed to 539MHz (DDR3-1079) if that makes sense. Is this normal? I've not tested the stability within windows just yet *** I'd like to see how well this RAM performs first and to see if there are any suggestions as to why this might be the case?

theboyfold Posted October 7, 2010 Author Share Posted October 7, 2010 What are the voltage and other BIOS settings I should be using for the RAM? Link to comment Share on other sites More sharing options...
trackrat Posted October 8, 2010 Share Posted October 8, 2010 The TR3X6G1600C9 memory is tested to run at 1600 MHz., 9-9-9-24 2T @ 1.65V. The CM3X2G1600C9 probably has the same timings/voltage but I can't confirm this?????? Your CPU however is only rated to run memory at 1066 MHz. The BIOS fail safe default setting is attempting to set the clock speed to the Intel official CPU max rated memory speed of 1066, (533 MHz. x 2). XMP overclocks the memory and may not run successfully with all of your hardware components. Manually setting the BIOS options is often required to obtain a stable overclocked system, assuming the hardware is willing to run overclocked. http://www.corsair.com/products/corei7/faq.aspx http://www.intel.com/products/processor/corei7/index.htm Useful reading: http://www.techreaction.net/2010/09/07/3-step-overclocking-guide-bloomfield-and-gulftown/ Link to comment Share on other sites More sharing options...
