hitheresi Posted December 9, 2006 Share Posted December 9, 2006 I'd like to get an RMA because I'm pretty sure one of these two sticks is bad. I can't seem to pinpoint the stick because the memtest errors don't happen unless they're both in and in dual channel. I didn't test with both in on the same channel because it's testing now at a speed of 250. The errors aren't too numerous and can happen right away or within a few hours. They are always at two specific spots though and always in the pair. No pass has had a single error at one of those spots without the other. Now the reason why I'm pretty sure one of them is bad and it's not the system at all is because I have another pair of the same memory which I used in the system and those two sticks are completely stable for 24+ hour periods as well as long windows torture tests. I popped them out after a quick 5 hour test and put in the 2 suspect sticks and got a quick two errors at the usual two spots on the third or fourth pass. During a 5 or so hour test with them I only managed to get 4 sets of 2 errors so it's not the tens/hundreds/thousands of errors type of problem I've seen with bad timings or other settings. I'm currently testing at a clock of 250 just to see if it can handle that and I'll try both on the same channel. So far I'm guessing one is bad but it doesn't get pushed over the edge until it's in dual channel. I guess it gets stressed a bit harder. I tried with bios defaults and underclocked everything else but that doesn't change anything. Voltage changes didn't seem to change much either. I haven't been able to get either one to error by itself yet with 10+ hour tests.

hitheresi Posted December 9, 2006 Author Share Posted December 9, 2006 After testing for about 90 minutes with both in dual channel at 250 I finally got a set of errors at the usual 2 spots. Next I'll try both in the same channel but I'm just about sure that one of the sticks is bad now. Link to comment Share on other sites More sharing options...
hitheresi Posted December 10, 2006 Author Share Posted December 10, 2006 After about 10+ hours testing I got a pair of errors with the suspect sticks in slots A1 and B2 so it wasn't dual channel. That was with auto settings setting the memclock to 133 as well so the ram was actually running at 180 since I had the hyper transport set to 270.

hitheresi Posted December 11, 2006 Author Share Posted December 11, 2006 I confirmed it was a bad stick by using each one with one of my known good ones. The bad one failed within a few passes while the good one lasted 14 hours before I stopped the test. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted December 11, 2006 Corsair Employees Share Posted December 11, 2006 Can you tell me the exact 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...
hitheresi Posted December 11, 2006 Author Share Posted December 11, 2006 The bad stick fails when set to 270 and I tried as low as 250 and also 180. 1T or 2T doesn't make a difference. I used the default timings of 2.5-4-4-8 and 3-4-4-8. Voltage from 2.70-2.85 was tried which made no difference. The other 3 sticks work fine at any setting I tried. I also used the auto settings for all the timings and ram settings as well which were more conservative settings than I tried otherwise. That didn't help either. I also used the 3 good sticks at once also and didn't have errors so it's definitely that one stick. Basically nothing I did could stop that stick from having errors. I have the system running fine now with the old pair.Let me know if there is other information you want. Link to comment Share on other sites More sharing options...
hitheresi Posted December 11, 2006 Author Share Posted December 11, 2006 I also did the tests with the cpu at stock and underclocked speeds with normal voltage. That didn't make a difference. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted December 11, 2006 Corsair Employees Share Posted December 11, 2006 Let's get them all replaced. Please use the RMA request found in TSXpress or follow the link in my signature “I think I have a bad part!” and we will be happy to replace them or it! And please note that you are from the forum!

hitheresi Posted December 13, 2006 Author Share Posted December 13, 2006 Thanks. You didn't mean to send all 4 back did you? Since the original pair works fine I wouldn't want to send them back unless it's absolutely necessary since I'll have to be without the system.

Corsair Employees RAM GUY Posted December 13, 2006 Corsair Employees Share Posted December 13, 2006 Yes I would suggest getting all of them replaced so they all match. And once you have the RMA number you should call and talk to our customer service and ask if there is any way to match all of the modules! Link to comment Share on other sites More sharing options...
hitheresi Posted December 13, 2006 Author Share Posted December 13, 2006 Are you sure they will test all four sticks thoroughly ? It would be pretty bad if I sent all four back and had to do without the system for a few weeks only to get them back and have a bad stick again.

Corsair Employees RAM GUY Posted December 13, 2006 Corsair Employees Share Posted December 13, 2006 All of our modules are tested on a MB at their rated speed before they leave the factory! If you still have problems I would suspect that you may be trying to run the memory to fast for your system configuration and most systems would need to run the memory at DDR333 with 4 modules installed! And I have not seen any MB that would run these modules at their tested settings with 4 modules. Link to comment Share on other sites More sharing options...
