vernon Posted October 21, 2010 Share Posted October 21, 2010 hi- have the combo as per title but am having a terrible time getting things to run as stable. i am happy to run the ram at 1333, speed issue isnt of that much of importance, a stable system being my preference with voltage set at 1.60 up to 1.64 i have tried 8-8-8-24 8-8-8-27 9-9-9-24 (motherboard default) 9-9-9-27 each with the same result, pc crashes with either memory management or you have overclocked the system as error messages. any suggetsions as to other tweaks would be great. also would it help to bump the cpu voltage? im not great with this sort of thing so please be gentle with me!! (running this on windows xp at present) Link to comment Share on other sites More sharing options...
trackrat Posted October 22, 2010 Share Posted October 22, 2010 Is your PC stable when you run the RAM at 1333 MHz.? Is the CPU overclocked? Have you run Memtest 86+ on one DIMM at a time to check for errors? With Cool and Quiet and C1E disabled in BIOS, your CPU voltage should be ~1.4 V +/-. A 9-9-9-24 2T setting @ 1.5 V would typically be the "auto" detected settings. You'd need to manually set anything different. Running the RAM at a higher frequency than 1333 MHz. may require an increase in the RAM voltage to 1.65 V (see the DIMM label for the specified voltage) and raising the CPU-NB voltage. Try 1.2 V on the CPU-NB. Link to comment Share on other sites More sharing options...
vernon Posted October 22, 2010 Author Share Posted October 22, 2010 hi- no overclocking memtest86+ shows no errors, pc not fully stable at 1333 but better than 1600! have everything set to motherboard default at present other than the ram voltage which is at 1.64. this is the most stable it will run. will try bumping the cpu-nb and see how we go :) thanks Link to comment Share on other sites More sharing options...
vernon Posted October 23, 2010 Author Share Posted October 23, 2010 could i ask another question here: my motherboard has CMD4GX3M2B1600C8 as being compatible, would this also make CMP4GX3M2B1600C8 compatible or is there a difference that would affect this? thanks Link to comment Share on other sites More sharing options...
trackrat Posted October 23, 2010 Share Posted October 23, 2010 Both kits are AMD Phenom compatible memory according to Corsair's actual RAM testing so they "should" both be mobo compatible also. Mobo makers only test a few RAM kits from RAM suppliers to help consumers find suitable RAM. Link to comment Share on other sites More sharing options...
I_Claudius Posted November 25, 2010 Share Posted November 25, 2010 How many sticks of CMP4GX3M2B1600C8 have you got in your DIMM slots? Link to comment Share on other sites More sharing options...
