Memory timings advice

I got bogged down with other issues over the last couple of weeks and did not get around to the timing tests as I had stated/indicated that I would. That is until today when I tried a few timing changes/reboots/Load Bios Defaults...and with the newly flashed ver 3.10 BIOS.

Although little can be added from my prior post, I now can confirm that not only do I always get boot DRAM errors when I attempt to use any entry on the 'OC Tweaker/DRAM Timings' screen but also with the latest BIOS I am down to 2933mhz...-sniff-, from 3066mhz with the ver 3.00 BIOS. - which was down from 3200mhz with ver 2.40/June AGESA 1.0.0.6 release.

The only way I get 2400/2666/2933 to work is to leave all entries on the 'OC Tweaker/DRAM Timings' screen to 'AUTO' and then enter my timings(some sub timings as well) on the 'Advanced/AMD CBS/DRAM Timings' screen.

I'll try to get images and possibly more tests this holiday(U.S.A) on Monday. Afterwards I may flash back to the version 2.40 BIOS even though I found voltage issues with that version. The 3.10 version appears to be just as stable with voltages as the 3.00 version from what I can tell over brief testing that I did today.

i was reading it as in he is getting this ALL  the time not just first boot

no it should when working correctly just start like any other pc

If you open the SPD tab of CPU-Z, you should find a Timings Table, with a number of Frequencies at the top, and the basic timing values below them. You must select a Slot (memory slot) at the top that contains a memory module. For example:



Frequency is one half of the actual speed of the memory. DDR means Dual Data Rate memory, the effective memory speed is twice the frequency.

In your board's UEFI/BIOS, in the DRAM Configuration screen, do you see an entry for DRAM Tweaker? If so, that is a feature that lets you easily choose among the timings programmed into your memory.

Or download Thaiphoon Burner, below, the free version, which will give you more information about your memory than you will ever need, including timing tables:

When entering timing I see that they are pretty much the same? http://www.corsair.com/en-gb/vengeance-lpx-16gb-2x8gb-ddr4-dram-3200mhz-c16-memory-kit-black-cmk16gx4m2b3200c16 SPD latency 15-15-15-36 - This number is always the same (2133,266,3000,3200mhz) What about option on the link Tested latency? EDIT: So for updating BIOS (x370 K4 - From 2.5 to 3.1) just to reset to default and update? I think someone wrote long time ago that clear cmos is really necessary... SPD latency is only for the SPD speed, which is the stock, non-OC speed, only for 2133. You might be able to use those values at say 2400, but they are not for the higher OC speeds. Tested latency on the page in your link is 16-18-18-36, at tested speed of 3200. You should see that in the SPD column for 3200 in CPU-Z. I don't see anywhere on that page 16-18-18-35. You could try using 35, but it won't make much if any difference.
