G.SKILL DDR3 Memory not running at advertised speeds

[charlie310]

I have G.SKILL F3-10666CL8D DDR3 1333 memory with advertised timings of 8-8-8-21. When manually changing the timings from 9-9-9-24 to 8-8-8-21 in BIOS, BIOS reverts back to 9-9-9-24. Your help would be appreciated.

MOBO: ASUS M4A87TD/USB3
CPU: AMD Athlon II X4 640

Using the most updated BIOS version.

Are you using any ASUS Utility i.e. AMD OverDrive Utility or ASUS AI Suite? If so those Apps override BIOS changes made 'manually' in the BIOS.

The better choice is not to use them, and set everything in the BIOS Manually. If you're not using some BIOS invasive App then I assume that you are 'Save & Exit = Yes' once the changes are being made. Lastly, if none of the above applies then swap out your CMOS battery.

^+1 i can't believe the advertised settings wouldn't work by default.

charlie310, the problem is that the AMD platform does not support Intel XMP profiles. The timings of 8-8-8-21 are from the XMP profile. Try out Thaiphoon Burner's DCT Tuner to set this timing set from withing Windows. DCT Tuner is more friendly and easy to use comparing with AMD AOD utility.
