fizi Posted October 11, 2009 Share Posted October 11, 2009 I've tried to piece together the correct configuration for this motherboard and 4 sticks of TWIN2X2048-8500C5D by searching the forums and reading "Dominator Qualifications and Testing!" thread RamGuy has in his forum sig. I was running a kit of TWIN2X2048-8500C5D previously at 1066mhz just fine. The kit was v2.x. I decided to stick more RAM in my system and bought another kit. It of course was v1.x. I've since gotten a third kit and now have 4 sticks of v1.x that I'm trying to get working on my computer. Motherboard is an Asus Commando with the latest BIOS. CPU is a Intel 2 Quad Q6600. Here are my results from memtest86+ v3.3: memtest results Here are my BIOS settings: Settings 1 Settings 2 Any suggestions would be much appreciated. I had this running stable with just a single kit in there so I was hoping putting a second kit in wouldn't be much of a struggle. Link to comment Share on other sites More sharing options...
Wired Posted October 11, 2009 Share Posted October 11, 2009 That's not Memtest86+, only Memtest86. That version is almost 3 years old, and as you can see in the picture, can't detect the chipset properly. Download Memtest86+ v4.00 (link on the left) and test with that.

fizi Posted October 11, 2009 Author Share Posted October 11, 2009 Wow is my face red. I've got Memtest86+ 4.00 this time and it's made it past test #5 with no errors so far. I'll leave the testing in a loop over night and report back if it continues with no errors. I wonder if I need to bother upping my NB VCore after all....

fizi Posted October 11, 2009 Author Share Posted October 11, 2009 Looks like it just took longer with the new version to start getting errors. memtest86+ 4.00 results Any suggestions on what I should try tweaking? Link to comment Share on other sites More sharing options...
Wired Posted October 11, 2009 Share Posted October 11, 2009 Considering the errors are OVER 4 GB, something's not right. Personally I'd run each stick separately through one loop to be safe. Aside from that, try lowering the speed to 800 MHz. Link to comment Share on other sites More sharing options...
fizi Posted October 11, 2009 Author Share Posted October 11, 2009 4 passes running at 800mhz with no errors. Guess it's back to the store for this RAM. No point in paying extra for DDR2-1066 when I could have just bought more (6-8GB) of DDR2-800 for the same price or less. Thanks for your assistance.

Corsair Employees RAM GUY Posted October 15, 2009 Corsair Employees Share Posted October 15, 2009 With 4 modules I would suggest setting the memory frequency at DDR667 or DDR800 and set the memory Voltage to 2.1 Volts and set the NB/MCH/SPP Voltage to +.2 Volts as well and test the system with http://www.memtest.org. In addition, with some MB's (Mostly ASUS) you have to disable legacy USB in the bios when running any memory test. Link to comment Share on other sites More sharing options...
fizi Posted October 15, 2009 Author Share Posted October 15, 2009 Interesting that the Legacy USB needs to be disabled. Would having it enabled generate errors in memtest? or just cause memtest not to function? I had the RAM running at DDR800 just fine but I was hoping to run it at DDR1066 since that's what I paid for. I could easily just get some DDR800 Corsair memory for cheaper or buy 2x2GB sticks at DDR1066 instead of trying to run 4x1GB sticks. Is it worth trying the settings you recommend at DDR1066? otherwise I've got my refund setup I just need to ship the memory. Link to comment Share on other sites More sharing options...

Corsair Employees RAM GUY Posted October 15, 2009 Corsair Employees Share Posted October 15, 2009 Interesting that the Legacy USB needs to be disabled. Would having it enabled generate errors in memtest? or just cause memtest not to function? A: It is listed in the Memtest Read me file and it may generate false errors or make the system unstable. I had the RAM running at DDR800 just fine but I was hoping to run it at DDR1066 since that's what I paid for. I could easily just get some DDR800 Corsair memory for cheaper or buy 2x2GB sticks at DDR1066 instead of trying to run 4x1GB sticks. A: This is more of a loading issue and we do not test Twin sets in 4 up configurations. So if you purchase 4 1.0 Gig DDR800 modules you may still have to lower them to the next lower speed grade. Is it worth trying the settings you recommend at DDR1066? otherwise I've got my refund setup I just need to ship the memory. A: I would just keep what you have and set them to DDR800 as long as the system is stable you should be fine. Link to comment Share on other sites More sharing options...
fizi Posted October 17, 2009 Author Share Posted October 17, 2009 After disabling the Legacy USB and trying memtest again with my originally posted settings I had 0 errors after 24 passes. memtest results Guess it pays to read the readme. Thanks for your help! I'll be keeping the RAM. Link to comment Share on other sites More sharing options...

fizi Posted April 4, 2010 Author Share Posted April 4, 2010 Just a quick follow up. After running the above settings stable since my last post I now appear to have a bad stick of RAM. I'm going to run individual tests on each stick to narrow it down. I think this is just a failed stick of RAM and not a settings problem. Even when bumping things down to 800mhz from 1066mhz and changing the timings to 5-5-5-18 I still see errors in Memtest86+ 4.00. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted April 6, 2010 Corsair Employees Share Posted April 6, 2010 Let's get them replaced, please use the On Line RMA Request Form and we will be happy to replace them. Be sure to check the box that says “I've already spoken to Technical Support and/or RAM Guy.” Link to comment Share on other sites More sharing options...
fizi Posted April 6, 2010 Author Share Posted April 6, 2010 I did individual tests and isolated a single stick throwing up errors. Thanks Ram guy! Already submitted an RMA. You guys are fast. I think I'm having additional problems. Trying to narrow down if it's the mobo of PSU. With the two good sticks of RAM I re-ran Memtest86+ on it. After 3 hours the interface froze on Memtest. Been having other random and strange problems. I ran Spinrite on my hard drives for 12 hours straight with no problem. Re-installed Windows 7 and start trying to copy my backups off my NAS and Windows BSOD's. There is an error in the event log about a sudden loss of power. I'm trying to scrounge a spare PSU right now to test with. Link to comment Share on other sites More sharing options...
fizi Posted April 21, 2010 Author Share Posted April 21, 2010 Since I can't seem to figure out how to send another message to Tech Support about my RMA I'll post it here. Do RMA's expire? I just shipped my bad RAM to you guys today but my RMA # was issued April 4th. The package should arrive to you in 4 days. If RMA's expire how can I ask for my RMA to be extended? I can provide a tracking number for the package if that's needed. Since this is a repair is there customs fees on the shipment? Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted April 21, 2010 Corsair Employees Share Posted April 21, 2010 Yes RMA numbers do expire after 30 days. Your RMA should be ok. As far as the custom fees you should not receive any however I do know some countries do have forms you can fill out to take care of those.

fizi Posted May 6, 2010 Author Share Posted May 6, 2010 So I got my replacement RAM. Corsair CM2X1024-8500C5D v4.3 which runs at 2.10v. Now what do I do? I sent you RAM that runs at 2.20v and you sent me back RAM that runs at 2.10v. I still have two sticks of 2.20v RAM in my computer which won't be compatible with the replacement RAM you sent.

Corsair Employees RAM GUY Posted May 7, 2010 Corsair Employees Share Posted May 7, 2010 Just go ahead and leave the memory at 2.2v it will be ok. Link to comment Share on other sites More sharing options...
fizi Posted May 7, 2010 Author Share Posted May 7, 2010 Darn. Wish I'd known that when I first bought this stuff. I originally had two 2.1v sticks and a year later bought two more that were 2.2v. So I ended up buying another matching pair of 2.2v not knowing I could have just run it all at 2.2v. Oh well. Thanks for all the help! I'll try the sticks tonight and run memtest on them with the settings I started this thread with. Link to comment Share on other sites More sharing options...
fizi Posted May 7, 2010 Author Share Posted May 7, 2010 System won't even post with mixed 2.1v and 2.2v RAM in it running with this threads BIOS settings. I haven't tested the two new sticks one at a time yet but let's pretend you guys didn't ship me DOA replacement RAM. Any suggestions as to what I should do next?
