NINaudio Posted January 18, 2006 Share Posted January 18, 2006 My system specs are listed in my sig. I am unable to stably run dual channel mode with twinx1024-4400c25 in my dfi lanparty expert mobo. I have tried very relaxed timings at 2T to no effect. I am unable to run prime95 in dual channel mode, and the system is generally unstable. I can pass memtest in dualchannel mode for over 70 passes of test 5, and 15 passes of everything with no errors. If I use a single stick of ram in the orange slot furthest from my cpu I can run prime95 without any problems. Please tell me what I can do, or if you need more info to help me out. I can post screens of my dram settings from the BIOS if wanted. Thanks! Link to comment Share on other sites More sharing options...
NINaudio Posted January 18, 2006 Author Share Posted January 18, 2006 I have everything set VERY loose in the hopes of getting dual channel working correctly and then optimizing later, but I had no luck doing that.... http://img.photobucket.com/albums/v231/NINaudio/bios%20screens/P1000291.jpg http://img.photobucket.com/albums/v231/NINaudio/bios%20screens/P1000292.jpg http://img.photobucket.com/albums/v231/NINaudio/bios%20screens/P1000293.jpg http://img.photobucket.com/albums/v231/NINaudio/bios%20screens/P1000294.jpg I have also tried the settings listed here: http://www.dfi-street.com/forum/showpost.php?p=242863&postcount=4 with no luck either.....

Corsair Employees RAM GUY Posted January 18, 2006 Corsair Employees Share Posted January 18, 2006 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...
NINaudio Posted January 18, 2006 Author Share Posted January 18, 2006 All my ram settings are shown in the bios screens that I posted links to. I currently have them set very loose in an attempt to get dual channel at least working correctly and then tweak it later. The system is not overclocked as of yet My settings in the genie bios are: htt: 200mhz ldt: x4 cpu multi: x10 cnq: disabled Dram voltage: 2.80v ram: 1:1 cpc: disabled tcl: 2.5 trcd: 4 tras: 8 trp:4 trc: 16 trfc: 19 trrd: 5 twr: 3 twtr: 2 trwt: 5 tref: auto twcl: 1 bank interleave: disabled dqs skew control; decrease skew dqs skew value: 50 dram drive strength: 7 dram data drive strength: level 2 max async latency: 8 dram response time: normal read preamble: 7 idleCycle limit: 256 cycles dynamic counter: disable r/w queue bypass: 8x bypass max: 7x 32 byte granularity: enable (2 bursts) Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted January 18, 2006 Corsair Employees Share Posted January 18, 2006 What do you have the CPU Frequency set to? Link to comment Share on other sites More sharing options...
NINaudio Posted January 18, 2006 Author Share Posted January 18, 2006 cpu frequency is set to 200 Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted January 19, 2006 Corsair Employees Share Posted January 19, 2006 Please make sure that you have the latest bios and then load setup defaults and set the following settings and test the modules one at a time with http://www.memtest.org and let’s make sure one is not failing! Dim Voltage 2.7 Volts CAS Latency CL=2 Row Cycle Time tRC Bios Default Row Refresh Cyc Time tRFC Bios Default Ras# to CAS# delay tRCD 2 Row to Row delay Bios Default Min Ras# Active Time tRAS 5 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 Link to comment Share on other sites More sharing options...
NINaudio Posted January 19, 2006 Author Share Posted January 19, 2006 what settings would you like me to use for memtest? (ie loop one test 50 times, or all test 20 times....etc etc., single sticks first, then dual channel?) 1t, 2t, or both? Edit: why would you want me to run memtest at tighter timings than what is listed for the ram? Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted January 19, 2006 Corsair Employees Share Posted January 19, 2006 DO NOT change any of the settings in memtest or you may get errors, just use the default tests for 2-3 passes And the modules you have will support these settings when running at DDR400 and would be a good way to make sure its not the system just will not over clock that well. So don’t over clock and leave the memory and CPU at 200 MHz with the settings I gave you and see if the system is stable. Link to comment Share on other sites More sharing options...
NINaudio Posted January 20, 2006 Author Share Posted January 20, 2006 memtest passed in dual channel, I let it go for 10 full passes; about 4 hours. I'm now running dual instances of prime95 to make sure it all works in windows. Once this is all going well at stock speeds I do plan to OC, should I leave everything as is in the BIOS with the exception of changing CAS to 2.5, tRCD to 4, tRAS to 8, and tRP to 4? Or does that go in a different section of the forum? The last mobo, MSI K8N Neo2 Plat, I had these sticks in I was able to run them at 250 2.5-3-10-3 without a problem, should I expect similar results?

Corsair Employees RAM GUY Posted January 21, 2006 Corsair Employees Share Posted January 21, 2006 You will just have to try it, may depend more on the CPU and bios more so than anything else. You just have to try it. Link to comment Share on other sites More sharing options...
NINaudio Posted January 23, 2006 Author Share Posted January 23, 2006 I can't seem to get anything but 2-2-2-5. I've tried 220mhz at 2.5-3-3-10 and 2.79v and it blue screens on me before I get into windows. I have to right now use the memory dividers to get it to run near 200mhz at 2-2-2-5 timings, and I haven't been able to go much higher than about 210 at those timings.

Corsair Employees RAM GUY Posted January 23, 2006 Corsair Employees Share Posted January 23, 2006 What do you have the HTT frequency set to? And how about the CPU multiplier set too? Link to comment Share on other sites More sharing options...
NINaudio Posted January 26, 2006 Author Share Posted January 26, 2006 HTT is 290, cpu multi is x9, ram divider is 7:10. This puts the ram right at DDR400, which works just fine. I have successfully run dual instances of Prime95 at these settings for 9 hours until I manually stopped them. If I try to get the ram much higher than 210 I have issues in Prime95. If I loosen up my timings to 2.5-3-3-10 when trying to go past 210 I get a blue screen before windows even loads. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted January 26, 2006 Corsair Employees Share Posted January 26, 2006 As you increase the memory frequency ratio you may have to lower your CPU Frequency as there will be more loading on the memory controller. Link to comment Share on other sites More sharing options...
NINaudio Posted January 30, 2006 Author Share Posted January 30, 2006 I've tried running them at a straight 1:1 ratio with a lower cpu frquency and looser timings with no luck either. It's no big deal if I can't get them higher, I'm perfectly happy with tight timings on a divider. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted January 31, 2006 Corsair Employees Share Posted January 31, 2006 Well you still have a great OC going. As the bios matures you may be able to get a bit more out of the system. Link to comment Share on other sites More sharing options...
NINaudio Posted February 1, 2006 Author Share Posted February 1, 2006 I still don't think it has anything to do with the bios, cpu, or the mobo as I've seen plenty of people with the same or very very similar setup able to achieve high ram speeds. I could almost certainly get much more out of this cpu if I wanted to take the time, but I had enough issues setting it up and getting the ram running in dual channel that I just wanted to get back to playing some games! If you happen to have any other suggestions on settings I could try, please let me know. Thanks! Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted February 1, 2006 Corsair Employees Share Posted February 1, 2006 You might see if a friend can load you another PSU to test with would be the only thing I can see that might be a issue. Link to comment Share on other sites More sharing options...
