lyandr Posted March 16, 2005 Share Posted March 16, 2005 Hello, i'am french so sorry for my bad english. I bought Twinx1024-3200XL, a cpu Athmon64 3500+ and a motherboard NF4 Ultra MSI K8N Neo4 Platinium. With paramters a default value (2225) and in dual channel mode (both module installed), if i run a SuperPI 32M i have errors at the first iteration. But if i change timing at 2,5 3 3 5 it's ok. After i decided to try one module, by one module. WIth the first one all is ok (memtest, superpi, prime95 etc...). With the Second one i have memtest error and the same trouble as in dual mode. So i think i have a bad part. Could you tell me what can i do? I also sent a email to the technical support (ramguy@corsairmemory.com) Regards Yann Link to comment Share on other sites More sharing options...
Captain_Morgan Posted March 16, 2005 Share Posted March 16, 2005 I too have a MSI Neo4 Platinum/SLI with an AMD Athlon64 3500+ running Twinx1024-3200XL memory. When I run the system in dual channel mode, I have errors with memtest86 with test 6 (about 1464 errors to be precise) and the system crashes constantly. I have adjusted the timming to 2 2 2 5 with voltage at 2.7V (max recommended for this board) with no luck. I have tried both slots 1&2 and 3&4 with no difference. I even tried running it with default bios settings with no luck. I can run in single channel with no problems. Not a single error is found, system is stable and I am using board detected settings in the bios. I want to run this system in dual channel and I am not sure what to do now. Any ideas. I know it is nothing else causing this problem due to genral troubleshooting procedures. This only seems to happen with the dual channel configuration. <EDIT> I up'ed the voltage to 2.8V and the errors decreased to 665 in test 6 of memtest86+. Also setting the the timing to 1T reduced the errors to 490. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted March 16, 2005 Corsair Employees Share Posted March 16, 2005 Please set the Dim Voltage to 2.8 Volts and then test the modules one at a time with http://www.memtest.org and if you find you have one module failing then please follow the link in my signature “I think I have a bad part!” and we will be happy to replace them or it! But if you get errors with both modules that might suggest some other problem. Link to comment Share on other sites More sharing options...
Captain_Morgan Posted March 16, 2005 Share Posted March 16, 2005 I finally tested both chips individually, at 2-2-2-5 and 1T 2.8volts, and the first chip passed, the second chip had 26 errors in test 6. Link to comment Share on other sites More sharing options...

Captain_Morgan Posted March 16, 2005 Share Posted March 16, 2005 Why would the system pass with flying colors in a single channel setup, but continuously fail in a dual channel setup? When I firist set up the system, I thought I was going crazy with all the random restarts. I could barely get the O/S installed without it rebooting when I was in dual channel. Even after it was loaded the rebooting (memory dumps) would occur at random. Then I went to a single channel setup, and the O/S installed fine, and not a single burb in the system since. Which is fine, but I picked this system for the dual channel. It just isn't making much sense to me. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted March 16, 2005 Corsair Employees Share Posted March 16, 2005 That would suggest either a power problem, or an issue with the memory controller. Some AMD 64 CPU's will just not run with agressive timings in dual channel. And you might check with the MB maker to make sure the PSU you have is compatible with your system.

Captain_Morgan Posted March 16, 2005 Share Posted March 16, 2005 I have an ANTEC True550EPS12V for my system. The voltages appear real stable +/- .03 volts when running. Why would it indicate a PSU problem when it runs like a champ in single channel, but when in dual channel it is highly unstable? I would buy a possible memory controller problem in the CPU.

Corsair Employees RAM GUY Posted March 16, 2005 Corsair Employees Share Posted March 16, 2005 As I know this platform most MB suggest you use a ATX 2.0 Compliant PSU and the PSU you have is NOT, so I would check with the MB maker to be sure there is no issue with that PSU. I think the NEO power would be compatible, but again please check with the MB maker to be sure. The difference is ATX 2.0 provides 2 12 Volts rails so all devices have enough power and even though the voltages are stable they may not be able to provide enough power. And yes its entirely possible that you have a failing CPU, but I would check on the PSU first to make sure. Link to comment Share on other sites More sharing options...
Captain_Morgan Posted March 16, 2005 Share Posted March 16, 2005 I thought all the 24 pin ATX power supplies where 2.0 compliant? I did ask their support guys about this, along with MSI's so I am waiting for the reply. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted March 16, 2005 Corsair Employees Share Posted March 16, 2005 No if you go to Antec site only the Neo power series is ATX 2.0 compliant. Link to comment Share on other sites More sharing options...
Captain_Morgan Posted March 17, 2005 Share Posted March 17, 2005 After testing the PSU with data given to me by Antec, the PSU is running in parameters. I haven't ruled it out, but I don't think it is it yet. MSI had a revision to the BIOS (one that I couldn't find without thier help) and I installed that, and reapplied all the settings to the memory. It has been running in windows now for about an hour without a sudden reboot. That is longer than the past. I will update if that was the helped. I also have tested both chips with many passes of memtest86+ and one still comes up clean, and the other has numerous errors on it. I just need to keep the system stable for a week, and then I can go from there. I will follow your insturctions on the RMA in about a week and see what happens.

Corsair Employees RAM GUY Posted March 17, 2005 Corsair Employees Share Posted March 17, 2005 No problem, please let me know. Link to comment Share on other sites More sharing options...
Captain_Morgan Posted March 18, 2005 Share Posted March 18, 2005 So far so good. I still get over a hundred errors in memtest86+, but for the most part, the system hasn't reboot on its own accord since getting version 3.1 of my bios. So for now I'm happy. I now have dual channel memory with the latencies that I wanted. Thanks for you help. If the system becomes unstable then I may RMA, but it is looking good for now. Thanks for your help.

Corsair Employees RAM GUY Posted March 18, 2005 Corsair Employees Share Posted March 18, 2005 You should not get any errors, can you tell me what test you are getting errors on? Link to comment Share on other sites More sharing options...
Captain_Morgan Posted March 18, 2005 Share Posted March 18, 2005 The errors are always on test #6 with memtest86+. I got a few freezes/BSOD since the last post. In discussing the power supply with the motherboard manufacture and the psu maker, they both agree that the Power supply is compaitble and shouldn't be causing a problem. It needed to be either ATX 2.0 or an SSI, which mine is the later. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted March 18, 2005 Corsair Employees Share Posted March 18, 2005 Ok that is good to know. Let's try replacing the modules and see if that solves the problem.
