yaz1485 Posted November 11, 2007 Share Posted November 11, 2007 i have the Asus P5n32-E Sli mobo, running vista 64bit Intel Core Duo 2 E6600 PQI 2Gb Ram (800mhz)(two 1Gb sticks) i'm trying to upgrade to 4Gb with the 'Corsair TwinX 4Gb Twin2X4096-6400C5' but every time i'v put the memory in i get blue screens. however it works fine with one 2Gb stick. i've updated my bios to the latest one. chipset for my mobo has been updated aswell. same occured when i added 2Gb corsaire memory to my existing "gb PQI memory..Blue screens. but when there is only 2Gb of ram in the system, it works fine. i know that vista ultimate 64 bit, can take 4Gb.

DerekT Posted November 11, 2007 Share Posted November 11, 2007 Insert a single stick into slot 1 and test with memtest. Do this with the same stick on all four slots. Then insert stick 2 in slot 1 and test with Memtest. Results? Link to comment Share on other sites More sharing options...
yaz1485 Posted November 11, 2007 Author Share Posted November 11, 2007 heres a mind boggler for ya! before you replied i was seeing how many Gb my motherboard would accept. it went up to three before getting blue screens. at the moment i got 4Gb corsaire that i mentioned ( 2 sticks of 1gb) and i've got my original 2Gb of pqi ram ( 2 sticks of 1 Gb). i put both corsairs sticks, total of 4Gb, in the first two slots (channel 1)..result blue screen. i then changes it so one stick sat in slot 1, and the other sat in slot 3 (1st slot of the 2nd channel).....result?................blue screen! i put one of the corsair sticks in slot 1 of the 1st channel, and put both sticks of my pqi ram in both slots of my second channel...giving me 4Gb ram....result?...............blue screen! then i took one of the pqi ram out and left corsair in slot 1 and remaining pqi in slot 3 (1st slot of 2nd channel)..result?......................... worked fine. to see if one of the sticks were daulty, i swapped the pqi that was in the system, with the one that i took out, and again it still worked! so my conclusion is that i don't think my mobo is accepting more than 3Gb! however it says it can accept 8Gb, 2Gb in each slot! so wats goin on? lol!

DerekT Posted November 12, 2007 Share Posted November 12, 2007 yup will do. could you please tell me how i can do a memory test? Certainly. Download memtest from http://www.memtest.org and extract the ISO image. Burn the ISO image to an CD-ROM disk. Boot to the optical drive with the memtest disk and allow for two full passes on each stick singly. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted November 12, 2007 Corsair Employees Share Posted November 12, 2007 Please post your Memtest results. With an ASUS MOBO, you will need to disable Legacy USB Support while running Memtest as this setting conflicts with the test. Also, mixing different brands of memory is not recommended. This could be the source of your instability. Link to comment Share on other sites More sharing options...
yaz1485 Posted November 13, 2007 Author Share Posted November 13, 2007 hi mate. i was jus browsing other forums, and i few people had the same problem as me. same mobo and vist au,timate x64! said it was to do with a (kb................777) patch. installed it with 2 Gb, shut down the pc and booted up with the 4GB corsair..................and it worked. had nout to do with mobo slots, cz i put both sticks in the same channel, when i tried it the first time (without the patch, it didn't work). however i keep getting the message about 'dipslay driver caused an error but now has recovered' message, a few time here and there.........................u know what that could be? was using the latest nvidia beta 169.04, so changed it to the official one. but same thing happened so i'v changed it to the beta one again.

Do you have another computer that you can test the video card in? If the problem occurs then you have isolated the issue. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted November 13, 2007 Corsair Employees Share Posted November 13, 2007 Some users have had to do a clean install of Vista to eliminate errors similiar to yours. Link to comment Share on other sites More sharing options...
tooon Posted November 13, 2007 Share Posted November 13, 2007 I had to update the BIOS to the latest version on my mobo along with the MS patch to keep my machine from crashing with 4GB. I have the same mb/cpu running on Vista x64. Link to comment Share on other sites More sharing options...
