Neil.Robinson Posted August 25, 2009 Share Posted August 25, 2009 Hi I am a newbie to computer building and have this problem. I am building a tower system for Photoshop. The computer mainly refuses to boot with the four sticks of memory installed. So far boots every time with 2X 2048 and 1X 1024 sticks of memory. Thanks in advance for any help.

Wired Posted August 25, 2009 Share Posted August 25, 2009 It's never recommended to mix memory sizes. Does each pair test ok? Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted August 25, 2009 Corsair Employees Share Posted August 25, 2009 With 4 modules I would suggest setting the memory frequency at DDR667 and set the memory Voltage to 2.0-2.1 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...
Neil.Robinson Posted August 26, 2009 Author Share Posted August 26, 2009 Thank you for the replies, I am a little nervous but I will try to adjust the settings as suggested and see how it goes. Thanks Neil. Link to comment Share on other sites More sharing options...

Neil.Robinson Posted August 26, 2009 Author Share Posted August 26, 2009 Thanks again. I had a go at replacing the extra 1gb module 2x2gb and 2X1gb. I did not get your suggested setting correct and it failed. I have now printed out your suggested settings and Will try again in the morning it is now midnight here. I may change the 2 X1gb modules for 2X2gb before I do. One more thing as I live in the UK is there a good time to contact tech support and is it done on line?

Wired Posted August 27, 2009 Share Posted August 27, 2009 Corsair is -8 GMT. They have no online chat if that's what you mean. They can be contacted via phone, email, TSX, or contact form. The only live option would be phone of course. Link to comment Share on other sites More sharing options...
Neil.Robinson Posted August 27, 2009 Author Share Posted August 27, 2009 Hi Wired Thank you very much for your trouble, I have tried the recommended bios settings but the computer refused to boot. My next move is to purchase a second pair of the 2gb modules when the shop opens and proceed from there. Thanks again Neil. Link to comment Share on other sites More sharing options...
Neil.Robinson Posted August 27, 2009 Author Share Posted August 27, 2009 Hi Ram Guy and Wired. Just some feedback, I now have 8Gb of memory installed two sets of 4gb Corsair Dominator PC8500 DDR2. Motherboard is an ASUS P5Q-E with an Intel Quad Q9550 2.83GHz, 4 hard drives, 2 DVD writers and 1 ATI 3800 series video card. My PSU is only a 450W, a few years old now originally a top of the range PSU but I fear now a little under powered. I intend to get a 600W ModXStream PRO. All the bios settings are set at this time to the auto settings, at this stage it is stable MB temperature is 39 Celsius and the CPU is about 26 C at rest. I am now feeling all of my seventy two years of age after all the problems getting the system stable. Cheers Neil. Link to comment Share on other sites More sharing options...
