nelsongs Posted October 28, 2005 Share Posted October 28, 2005 What is the best settings for these specs? I am running a pair of Nvidia 6800GTs in SLI mode, and have an Intel Pentium D 830 3.0GHz, with a bios version of 0708 on the Asus motherboard. What should be the settings to make it stable? Please help. Thanks. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted October 28, 2005 Corsair Employees Share Posted October 28, 2005 I would set the memory voltage to 2.1 Volts and you can follow the link in my signature for the tested setting of your modules. Link to comment Share on other sites More sharing options...
nelsongs Posted October 28, 2005 Author Share Posted October 28, 2005 i tried the settings you told me, but no success. any other particular settings for this motherboard to work with the TWINX2048 6400? Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted October 28, 2005 Corsair Employees Share Posted October 28, 2005 Can you tell me the bios settings you have set for both CPU and memory and any performance settings that you may have set? And what is the problem that you get? Link to comment Share on other sites More sharing options...
nelsongs Posted October 29, 2005 Author Share Posted October 29, 2005 It just didn't post if i set the RAM Freq to 800MHz with the DRAM voltage of 2.1V. For the performance settings, all were just default. The only things I configured were the DRAM timings, 5-5-5-12-5 and the clock cycle was set to Auto (there were two choices here, 1 or 2). The other things I configured were the performance, set to manual to configure the CPU/Mem Freq and set both to 800MHz. The PCIe was default to 100, which is the minimum. I'm using the bios version 0708. Link to comment Share on other sites More sharing options...
DownBringer Posted October 29, 2005 Share Posted October 29, 2005 I've had the same problem - you need to upgrade your nforce chipset drivers upto 7.13 Then update your bios to 0802 - most people that have had problems using the 0802 bios whilst using dual core processors, reset their bios settings back to default - which sorted that out - I have Pentium D 830 but never had any problems after upgrading to the 0802. Put the Overclock mode to manual in Jumper Free Configuration (I think thats where the oc settings are) and manually adjust the voltage to 2.1v, nothing higher or it may damage your memory. I'm using the PRO version of the TWIN2X2048 6400, I've the odd system freeze and immediate reboot but nothing as bad as it was prior the 802 bios upgrade. Make sure before you update your bios that create a floppy disk with the 0708 from ASUS support website - or you can download it here so if you have any problems you can easily revert back to the original 708 bios. ASUS' support with the motherboard has been ****! and in my eyes I wouldn't actually recommend this mobo to anyone, unless I really hated them.

nelsongs Posted October 31, 2005 Author Share Posted October 31, 2005 I tried to use the Bios V0802, but looks very unstable. It gave me Bios Checksum error for all three boards that I upgraded to 0802. It didn't look like a problem with the motherboard that I have because this is the third that I used. That's why I've been using the 0708 and there really aren't much of difference, as what I noticed with the parameters, and even in the Asus website. I tried to use the timings given by Ramguy, 5-5-5-12, with the voltage of 2.1Volts, but didn't post. When I set the Chipset settings to Auto, the mobo sees the DRAM timings to 5-5-5-18 with clock cycle 2T. Frequency settings were 800MHz for both CPU and DRAM, with PCIE at 100MHz (default). Setting the DRAM voltage to 1.9 Volts with this DRAM timings didn't post as well. What I did next was set timings to Auto, then set DRAM voltage to 1.9V, CPU freq set to 800MHz, but lowered the DRAM freq to 667MHz. I was able to post, run Windows, but just trying to play MP3 using Windows Media Player would freeze my system. It even freezes when I ran 3DMark 2005. To this stage, I'm not sure what's going on with my system. I checked the Corsair's website again for the memory modules compatible with my motherboard, and the TWIN2X2048-6400, the one I'm using, is listed as one of the compatible modules for my motherboard. So, where am I gonna ask for help now? Just want to remind everybody again, I'm running on SLI mode, with 2 Nvidia 6800GTs. Please tell me what to do, the exact parameters I should check. Ramguy told me to use the tested settings, and the DRAM voltage parameter, and I have used them all, but didn't work. All the parameters were at default, and I was just changing the ones Ramguy suggested. Link to comment Share on other sites More sharing options...
nelsongs Posted October 31, 2005 Author Share Posted October 31, 2005 Okay, this is what I noticed. When I tried to set the DRAM voltage to 2.1Volts, and set the frequencies for both CPU and DRAM to 800MHz, with the rated timings you told me Ramguy, it posted, but then tells me that the Windows system is corrupted and I have to do the Windows recovery. And when I restarted, it just gives me a bios checksum error. It happened to all the three same Asus P5ND2SLI boards that I've been testing. And this doesn't look like a problem with the board. When I tried to reset the bios settings again, set the DRAM timings to the specified settings, and set the DRAM voltage to 1.9Volts, it posts, but gave me a bluescreen, and then immediately reboots. Tried to decrease the DRAM freq to 667MHz, with the same DRAM voltage, it gives me a post, boots Windows XP, but hangs when I tried to play MP3 and run 3DMark05. What now? Please help!

Corsair Employees RAM GUY Posted November 1, 2005 Corsair Employees Share Posted November 1, 2005 Please set the memory frequency at DDR667 and see if the system is more stable. Link to comment Share on other sites More sharing options...
nelsongs Posted November 1, 2005 Author Share Posted November 1, 2005 I set the memory frequency to 667MHz and it booted Windows XP, but by just playing MP3, the system freezes. I tried to set the voltage to 1.9 and even 2.1 but still freezes. What's next? Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted November 1, 2005 Corsair Employees Share Posted November 1, 2005 If the system is freezing that would normally suggest some other problem. Can you run http://www.memtest.org on the modules and see if it will pass 2 or 3 passes? Link to comment Share on other sites More sharing options...
nelsongs Posted November 2, 2005 Author Share Posted November 2, 2005 I tried one module at a time running memtest and both of them passed for 3 passes. I tried them both too, and they both passed. I tested the other two boards, and the other pairs of Leadtek video cards too, and still, the systems were unstable when running just for playing music. What seems to be the problem then? I have tested two power supplies just to isolate the problem is, but still nothing. Any other suggestions Ramguy, please? THanks. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted November 2, 2005 Corsair Employees Share Posted November 2, 2005 That would suggest the problem is not with the memory. Have you talked to the MB maker? Also I would suggest testing the memory and CPU in another system if you can. Link to comment Share on other sites More sharing options...
nelsongs Posted November 2, 2005 Author Share Posted November 2, 2005 i contacted them already but never replied yet. i'll keep you posted for updates. thanks for the help. Link to comment Share on other sites More sharing options...
Yellowbeard Posted November 2, 2005 Share Posted November 2, 2005 I realize it is an enormous job but, you may need to strip the system to a bare system to see if you can isolate your instability. I would suggest a single video card, 1 stick of RAM, and the CPU. See if it will boot and run Memtest. Then, add ONLY the drive with the OS and see if you can run the OS stable. Then, if you can run stable, add the 2nd stick of RAM and reverify. Then, if still stable, add the 2nd video card and reverify. Also, if you have determined that it is not the RAM, we'd be happy to assist you at the http://www.houseofmobos.com Good luck, Mike. Link to comment Share on other sites More sharing options...
