ShaneC Posted November 12, 2004 Share Posted November 12, 2004 I have recently built a new rig. MSI K8T Neo2-F TWINX1024-3200XL BFG 6800 GT 500W PS XP-PRO SP2 I have had constant BSOD and complete system lockups. I have tried RAM slot combinations of 1&3 and 2&4. I have the memory voltage set to 2.75 and timmings of 2-2-2-5. I have rebuilt the OS 4 times and problem never goes away. I have tried driver upgrades and downgrades for video and sound just to see this is my problem. I have also loaded the latest MSI BIOs image. Still having issues. Does anyone know if I am running into some sort of compatibility issue between these components. SC Link to comment Share on other sites More sharing options...
Wired Posted November 12, 2004 Share Posted November 12, 2004 Try 2-3-2-5, where the 3 = RAS to CAS delay. Link to comment Share on other sites More sharing options...
ShaneC Posted November 12, 2004 Author Share Posted November 12, 2004 I can't try this till I get back to PC this evening but this fixes my problems I will be one happy camper. SC Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted November 12, 2004 Corsair Employees Share Posted November 12, 2004 You should set the Dim Voltage to 2.8 Volts as well. Link to comment Share on other sites More sharing options...
ShaneC Posted November 12, 2004 Author Share Posted November 12, 2004 I got another ?. Like I mention above I have my memory installed in DIMM Slots 1&3 currently. I just carefully read through MSI site an found that they reccomend that Dual Channel configuration should be in 1&2 or 3&4 or 1,2,3&4. Do I simply have my memory installed incorrectly? http://www.msicomputer.com/product/p_spec.asp?model=K8T_Neo2-F&class=mb If this is the case and I do have my memory installed incorrectly should I still monkey with Memory timmings and Voltage or should I leave it at 2.75 and 2-2-2-5?

ShaneC Posted November 12, 2004 Author Share Posted November 12, 2004 I have doubled checked I have one dim in the green slot 1 and one dim in slot3 which is the first purple slot. I think I am ok there. Sorry about that last post. SC Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted November 12, 2004 Corsair Employees Share Posted November 12, 2004 Please check the user manual for the correct slots. and I would set the timings to whats listed bellow with the Dim Voltage at 2.8 Volts. With this MB I would suggest you set the Rass to Cass to "3" so I would set these timings and then set the Dim Voltage to +2.8 Volts: CAS Latency CL=2.0 Row Cycle Time tRC Bios Default Row Refresh Cyc Time tRFC Bios Default Ras# to CAS# delay tRCD 3 Row to Row delay Bios Default Min Ras# Active Time tRAS 11 Row Precharge Time tRP 2 Write Recovery Time Bios Default Write to Read delay Bios Default Read to Write Delay Bios Default Refresh Period tREF Bios Default Enable 2T Timing Disabled Then test the system with http://www.memtest.org and make sure it's stable! If you have problems, I would set Enable 2T Timings to AUTO and test it again! Link to comment Share on other sites More sharing options...
ShaneC Posted November 13, 2004 Author Share Posted November 13, 2004 Ram Guy, So far with those settings I have made 7 passes with Memtest86 and no errors. I am not sure how long this needs to run so I am going to let it go for a while. Currently it has ran for 2 hours. I have seen other post that talk about running this for 10 hours so I am going to let it run for at least 10 more. Now the settings you have recommended are a far cry (not a bad game ;-) ) from the factory specs. What gives? Will I be able to at least drop "Tras" back down to 5? I will be most curious to see how 3Dmark responds and Doom3. I will keep my fingers crossed! SC Link to comment Share on other sites More sharing options...
ShaneC Posted November 13, 2004 Author Share Posted November 13, 2004 I have ran Memtest for 14 hours at the recommended settings error free. Whats next? Should I try 2-3-2-5 and see what happens there? I did run 3Dmark CPU test and I got a BSOD IRQL less than or equal when switching between the flying boat and space demo test. It was bombing during the boat demo everytime so I did manage to make it through an entire pass (1st time). Also I didn't configure anything in the memtest. I let it boot up and start running and let it roll. Shane Link to comment Share on other sites More sharing options...
ShaneC Posted November 15, 2004 Author Share Posted November 15, 2004 Ok my system is runing very stable with Mem V = 2.80 and 2-3-2-11 1T settings. After enabling 1T setting I have not had any BSOD for 3DMark, Doom3, or Dr. Hardware apps. I have ran the Everest Memory Test and it reports my latency to be 2.5-3-2-11. :confused: Is this the best result I can expect from this MoBo/Memory combo? If so I should have save my self some money and got some cheaper memory. I am going to attempt 2-3-2-5 tonight with Memtest to see what happens.

Corsair Employees RAM GUY Posted November 15, 2004 Corsair Employees Share Posted November 15, 2004 Shane, please check with the MB maker and make sure that you have the latest bios and or the bios you have properly supports the CPU you have.

ShaneC Posted November 15, 2004 Author Share Posted November 15, 2004 I had verified that previous to to posting in this forum. The MB only supports Socket 939 processors. I also mentioned in my first post that I had loaded the latest version of BIOs. Here is a quote from their website in regards to CPU support. CPU • Supports 64-bit AMD K8 Athlon 64/Athlon 64 FX Processor (Socket 939) • Supports 64-bit AMD K8 Athlon 64 3500+ and higher CPU • Supports 64-bit AMD K8 Athlon 64 FX processor FX-53 and up I have a 3800+ CPU. I also have a thread going in the MSI support forum and currently I have been given advice there to check memory and power supply. I have a 500W power supply that supplies 24A so I don't think that its the issue. Shane Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted November 15, 2004 Corsair Employees Share Posted November 15, 2004 The latest bios for this MB K8T Neo 2 939 is Bios Ver. 3.2., do you have this version installed? And do you have the ability to test the modules in another system? Link to comment Share on other sites More sharing options...
ShaneC Posted November 15, 2004 Author Share Posted November 15, 2004 I do have version 3.2 installed. I really do not have a another system to test the modules in. I wish though :) ! I have friend who lives a few hours from me who has my exact same setup (Mobo/processor/memory.) As a matter of fact I sent him my invoice and he built the exact same system. He has not had the same stability issues that I have ran across. He is setup like this though. Dim V=2.7 Timing = 2-byspeed-byspeed-byspeed all @200Mhz. I had him try 2.75 and 2-2-2-5 and he had stablility issues. BSOD and a few lockups. So he was happy to go back to the old settings. My PC on the other hand has not been stable till I tried your recommended settings. Shane Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted November 15, 2004 Corsair Employees Share Posted November 15, 2004 Well we can try replacing the modules if you like, but stability issues can be caused from many things, not just the memory. Like a noisy PSU is probably one of the most likely causes of this symptom. Please follow the link in my signature “I think I have a bad part!” and we will be happy to replace them or it!

ShaneC Posted November 15, 2004 Author Share Posted November 15, 2004 I tell you what. Let me try the test tonight with the following settings. 2.80 and 2-3-2-5 and see what happens with Memtest86. If all goes well and I don't have BSOD when running a few intense apps. I am willing to live with what I got. I would want to take some sort of action if I can't improve the current settings. BTW, is there any reason that Everest Bench would detect my latency settings at 2.5-3-2-11 when I am set to 2-3-2-11? I just thought that was interesting.

Corsair Employees RAM GUY Posted November 15, 2004 Corsair Employees Share Posted November 15, 2004 I would suggest you check at MSI's user forum to be sure, but I think you have to enable high performance mode under memory configuration. Link to comment Share on other sites More sharing options...
ShaneC Posted November 16, 2004 Author Share Posted November 16, 2004 Turns out I am good at 2-3-2-5 1T. Everest Bench Mark still showing latency to be 2.5-3-2-5. I was able to pass all test on Memtest86 I let 4 pass complete and then tried my Windows apps. 3Dmark Highest Score yet (5308). Doom3 ran with no issues. I tried 2-2-2-5 on Memtest and failed test 5 on the first pass. :( I am going to leave the setting alone for a couple of days and see if everything remains stable.

Corsair Employees RAM GUY Posted November 16, 2004 Corsair Employees Share Posted November 16, 2004 No Problem, our modules are guaranteed for life so we will be happy to replace them anytime should we need to do so. But I would wait till the next bios release to be sure. Link to comment Share on other sites More sharing options...
ShaneC Posted November 29, 2004 Author Share Posted November 29, 2004 Ram Guy, I would like to start the RMA process with my memory modules. Since our last communication my PC has had intermitten problems. During the past holiday I was able to use this PC much more than normal. I had several BSOD. Using the same settings that was last discussed (V= 2.80 Latency = 2-3-2-5) I am now failing test 3 and test 5 of Memtest86. I will follow the link in your signature to get the RMA started. I just wanted to update the thread so the RMA would not come as a surprise. Shane. Link to comment Share on other sites More sharing options...

ShaneC Posted July 11, 2005 Author Share Posted July 11, 2005 RamGuy, I never RMA'd my memory from the last time we spoke. My wife insisted on needing the PC and didn't mind suffering through the BSOD and reboots. I have decided to buy new memory to see if this makes a difference (still failing test 3 and 5 on memtest) and if does, work on replacing the memory I currently have. I noticed that now Corsair has new memory for Athlon 64 systems. Is this due to all the problems people were having with the standard Corsair LL memory sticks when paired with the Athlon 64 systems. I can only imagine there had to be some initiative for making this custom memory. I also notice that timing settings are slightly less than some of the standard XMS LL sticks. From looking at the product information all the AMD 64 memory I read about on the Corsair site was tested on a ASUS MB. I have the MSI setup so I am a little concerned about compatibility issues and running into more problems and be out another $250 bucks on this system. I plan on purchasing the TWINX1024R-3200C2. <- Your thoughts on this buy. Regards, ShaneC Link to comment Share on other sites More sharing options...

The R stands for registered, which is not compatible with 939 boards! TwinX1024-3200C2 is fine however.

ShaneC Posted July 11, 2005 Author Share Posted July 11, 2005 I am confused. Registered XMS - Designed Specifically for Athlon 64 FX Are these for the newer Processors? SC Link to comment Share on other sites More sharing options...
Garvin Posted July 11, 2005 Share Posted July 11, 2005 Yep they're designed for those cpu's, BUT are used in server motherboards NOT your MSI board. The "R" versions won't run at all on your board, as it doesn't have the additional circuits needed to make use of the extra error checking register circuits on the "R" version sticks. Wired provided the following link: Recommended Modules for the MSI K8T Neo2-F Left click on the above underlined link to see Corsair's list of compatible ram for this board. ps: When using two double sided sticks (the sticks you currently have) for dual channel in this board, MSI says to use dimm slot 2 (green) and dimm slot 4 (purple), not slots 1 and 3, or problems will ensue according to Msi. Msi also warns to always plug a stick into the green slot first. Msi Link for your board- http://www.msi.com.tw/program/products/mainboard/mbd/pro_mbd_detail.php?UID=608 ps2: Good luck.
