Corsair Employee RAM GUY Posted October 19, 2011 Corsair Employee Share Posted October 19, 2011 I would check for the memory controller Voltage and try and increase it +.2 Volts, might be called NB/MCH or just NB Voltage. Link to comment Share on other sites More sharing options...
memnot Posted October 20, 2011 Author Share Posted October 20, 2011 Still got the same problem, iv been trying to increase the NB voltage by +2 verytime untill 1.26 but still the same problem.

Corsair Employee RAM GUY Posted October 20, 2011 Corsair Employee Share Posted October 20, 2011 What do you have the timing set to? Cas 5, TRCD 5, TRP 5, TRAS 15 and what is TRFC being set to? Link to comment Share on other sites More sharing options...
memnot Posted October 21, 2011 Author Share Posted October 21, 2011 Using CPUz, timings: Dram frequency: 400mhz FSB:Dram = 5:6 CAS# letancy (CL): 5.0 TRCD: 5 TRP: 5 TRAS: 18 TRFC: 52 CR: 2T Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted October 21, 2011 Corsair Employee Share Posted October 21, 2011 I would set the memory frequency to DDR667 and increase the memory Hub Voltage (NOT Memory VDIM) it will be called like NB or NB/MCH voltage. And I would increase it +.2 Volts and try setting the TRFC to a higher setting if possible like 64. Link to comment Share on other sites More sharing options...
memnot Posted October 23, 2011 Author Share Posted October 23, 2011 Memory frequency is set to DDR667 in BIOS. NB is set to 1.24 (was set to auto). Tried TRFC at 64 bit didnt help so put it to highist 132. Still the same problem, what else can i change? Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted October 25, 2011 Corsair Employee Share Posted October 25, 2011 Have you tested all of the modules one at a time with http://www.memtest.org to be sure one is not failing? And please note with most ASUS MB's you have to disable legacy USB when running http://www.memtest.org. Link to comment Share on other sites More sharing options...
memnot Posted October 28, 2011 Author Share Posted October 28, 2011 Yes i have tested all individually. Link to comment Share on other sites More sharing options...

memnot Posted November 4, 2011 Author Share Posted November 4, 2011 Got it working! was playing with over clocking settings etc but nothing seemed to work. It was ok at NB=2.0 and dram=2.10 but still some issues. Reset everything back to default and set nb=1.20 everything else auto/default and it worked fine for some reason. Now thinking about getting a Asus ATI Radeon HD 6950, might need to upgrade my PSU thou. Just waiting on my headset being sent back from you guys and im good to go for skyrim :D Link to comment Share on other sites More sharing options...
