sharan_ahuja Posted July 11, 2009 Share Posted July 11, 2009 Hi, I just bought a new system (see dropdown). Running Bios Version F7 which is the latest .. Now the problem i am having is getting the ram stable @ 1600 Mhz. OCCT and LinX both crash on me in under 5 minutes when i run the ram @ 1600 mhz.I have no problems with the ram set to 1333 Mhz and the machine seems to be stable even after 30 mins of OCCT or LinX. I have tried with XMP enabled and disabled and it makes no difference at all to the stability at 1600 mhz. I still get crashes in under 5-6 mins. Nothing like this happens with the ram set to 1333mhz. I have set the ram manually to 1.65V and the Qpi to 1.36V and am not stable . I have NOT OVERCLOCKED the CPU at all. Just trying to get the ram to run at 1600 mhz and i cant even seem to do that much. My setting are Cl 8-8-8-24 2T @ 1600 mhz and i cant get stable. I tried QPI volts all the way up to 1.4V and still was not stable. But what i did notice is that the UD5 is not picking up the correct timings for the Ram. I would highly appreciate it if someone could give me the Sub Timings for my ram so that i can run it @ 1600mhz and get stable. these are my current settings on the UD5 and i cant get stable with them..

And i dont think i have a bad Mobo either cause i can run the ram @1333 mhz stable on OCCT for 30 minutes no problem but i crash in under 5 minutes with my ram @ 1600 mhz Thanks in advance for all the help guys and cheers :) Hope i can get to the bottom of this... :) Link to comment Share on other sites More sharing options...
