carcass_dev0 Posted July 27, 2006 Share Posted July 27, 2006 hi there! like you can see in my profile i got a corsair CMX1024-3200C2 pair, which i would like to run at dualchannel mode. my motherboard: MSI K7N2 Delta2 LSR. in singlechannel mode it works quite perfekt, without any errors in memtest86 within about 3 test-cycles. but if i make a dualchannel-configuration i always get some errors on test 5, it doesn't care which slots are the memories in. tried combinations: slot 1: mem1 slot 3: mem2 slot 1: mem2 slot 3: mem1 slot 2: mem1 slot 3: mem2 slot 2: mem2 slot 3: mem1 --> a lot of erros at test 5 slot 1: mem1 slot 2: mem2 --> no errors within 3 test-cycles the strange thing is, that i don't have obvious errors/malfunctions under linux, just windows while playing games is crushing the whole time... straaaange.... here are the appropriate bios-settings: no CPU-overclocking FSB: 200 MHz memory clock: FSB: 200 MHz memory voltage: 2,75 V memory timings: 2-2-2-6 i also tried less voltage but this didn't change anything. according to corsair the memory is also tested with 2,75 V and the 2-2-2-6 timings. and now the magic question: i have bad modules? or seem some bios-settings to be incorrect? i look forward if someone can give me some help! many regards, phil RAM GUY, i know that you read this :P please help me :!: Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted July 27, 2006 Corsair Employees Share Posted July 27, 2006 Phill, First thing, the timings should be Cas 2.5-3-3-6 with that MB not 2-2-2-6. And the modules should be in slots 2-3 and set the memory voltage to 2.75 Volts! Link to comment Share on other sites More sharing options...
carcass_dev0 Posted July 27, 2006 Author Share Posted July 27, 2006 ok, thanx for the first time ;) but these settings won't work either :(: on the total pass of 40 percent (test 5) memtest86 reports many many errors... hmm, why does memtest86 recognize the BIOS-setting Cas 2,5-3-3-6 as "2-3-3-6"? is this an kown issue, or it doesn't matter? i don't get it... why doesn't work it with dualchannel mode? i've tested so many different settings... if the memory-modules are bad it won't work in singlechannel modus either, will it? many greets, frustrated phil Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted July 28, 2006 Corsair Employees Share Posted July 28, 2006 What are the exact bios settings you have set? Link to comment Share on other sites More sharing options...
carcass_dev0 Posted July 29, 2006 Author Share Posted July 29, 2006 hi RAM GUY i'm just desperate about this! yesterday i tested my memory modules within the system of a friend and everything worked well! the ominous test 5 "block move" run 5 times without showing errors, in dualchannel mode! we tested different slot-memory combinations and every configuration worked! i tested my friends cheap lowcost memory which worked well in dualchannel-mode on my MB, without showing erros on memtest at all. now i guess that this memory is completely incompatible in dualchannel mode against this MSI board as well as my old MB (EPoX 8RDA+) which got broken somehow. do you know something about this? buf if you have some tricks left, please let me know. here are my relevant bios-settings (too lazy to write this stuff manually *g*): http://img81.imageshack.us/img81/4921/settingshn9.jpg bios version: http://img82.imageshack.us/img82/1189/startscreenmw7.jpg many regards Link to comment Share on other sites More sharing options...
Wired Posted July 29, 2006 Share Posted July 29, 2006 when you tested successfully your friend's memory in your system, what were the memory timings / voltage? tried updating the bios? Link to comment Share on other sites More sharing options...
carcass_dev0 Posted July 29, 2006 Author Share Posted July 29, 2006 i don't remember the exact settings, but i know that i let the default/SPD settings. but i'm sure that i already tested my memory with these settings, because i tried every damn configuration! Oo and you have to keep in mind, that his memory was another one than mine (very cheap one :D: ) about one month ago as i bought the MB i made the last BIOS-update! i guess my BIOS is up2date...

carcass_dev0 Posted July 29, 2006 Author Share Posted July 29, 2006 ok i just checked it out, my BIOS is up2date! there are no newer revisions. while testing today i suddenly realized some strange happening: my bootloader grub needed about 12 seconds to show the os-selection-screen. in several forums i read about a possible forthcoming harddisk-crash when the superblock-entries slowly get lost. maybe this is a possibility for some errors?

Corsair Employees RAM GUY Posted July 31, 2006 Corsair Employees Share Posted July 31, 2006 Let's get them both replaced. Please follow the link in my signature “I think I have a bad part! Or *New* Tech Support Express” and we will be happy to replace them or it! Link to comment Share on other sites More sharing options...
carcass_dev0 Posted August 1, 2006 Author Share Posted August 1, 2006 i don't think they are bad, because they worked well on my friends MB. we made extensive tests with prime95 and memtest86 and no error occured. i'll just sell the memory and buy a compatible lowcost memory which has almost the same performance but more than 50 EUR cheaper... anyhow, thank you for your attention ;) Link to comment Share on other sites More sharing options...
