Rpasma Posted August 10, 2013 Share Posted August 10, 2013 Hopefully the problem described below will be an obvious one you can help me with. Where I am at now: A brand new ASUS M5A99X EVO R2.0 MB with one Corsair CMX16GX3M2A1600C11 8 GB memory module, will start the BIOS setup menu, however fails to boot the Windows 7 64bit OS. The Windows 7 splash screen starts with the Windows title at the bottom of the screen. After several seconds four different colored dots appear and start a jerky circular movement. Before they get very far the OS shuts down and restarts the BIOS boot. Where I have been: A MSI 970A-G46 MB, two memory modules, and most of my current components was not recognizing a DVD drive and causing an occasional OS freeze, requiring a power or reset button push. Memtest86 did not indicate any problems with memory. Unplugging and exchanging components along with different cables did solve the problem As the MB seemed to be the problem the ASUS board was purchased figuring, even if I was wrong, a better MB would be gained. What has been done: The Asus MB BIOS was updated to Version 1903. To minimize memory problems only one of the 8gb memory modules in recommended DIMM Slot A2 was used. Doing this with each of the memory modules produced the same result. The Dram frequency was left at 1333 MHz and the DRAM timing was reduced to 11-11-11-32 with a voltage increase to of 1.5 volts (Factory recommended specification) with no effect. Observation: None of temperatures or voltages displayed by the BIOS menu after running for over 15 minutes showed any variance, or were excessive. The other stuff: CPU: AMD FX-8120 BIOS reported voltage 1.368v Power Supply: Antec 500W GPU: ASUS HD7770-DC- -V2 Radeon HD 7770 GHz Edition 1GB One 2 TB Hitachi and one 2 TB Western Digital SATA hard drives. Both have bootable copies of Windows 7 and both fail in the same manner described above. I am at a total loss as to what the problem might be or what to do at this point. Any comments or suggestions towards solving this problem would be greatly appreciated. Thank You, Rich Pasma:biggrin: Edit: This problem was also submitted to Asus tech support and placed on the Asus forum. A reply from Asus tech support is supposed to be given within 48 hours (Probably Business Day Hours). Once the problem is resolved, the solution or lack of one will be posted here. In the past both Asus and Corsair have given me excellent tech support. Asus would seem to be in a better position to answer this question since the Bios on this motherboard has a gazillion memory setting. Corsair’s staff would without a doubt understand all these memory settings, however, I wonder who else in the working, forget the consumer level, would.
