What I really need to do is test memory with CPU at stock speed (one variable at a time). Get that stable and then work on upping CPU clock...Might do some testing this weekend.

Yeah that's the ticket.

1/ Max stable cpu oc with default ram

2/ Ram stable oc with default cpu

3/ Combine the 2 and test again, hopefully they work together and are stable if not more testing and adjustments will be needed redface.gif

Option with a bunch of memory profiles, i tried the one that just about mached my SPD (it had extra voltage) and it just bricked the thing. Cleared CMOS and went back to stock memory speeds. Supposedly this bios even has the updated AGESA code. Using G.Skill Flare X 3200 14-14-14-34 and an 1800X @4ghz.

I have the same exact memory and cpu. XMP worked ok. But it does not work in tandem with memory try it. It is one or the other , not both. Hope that is your issue. Easy to fix.

So why are my 4 Flare X DDR4 3200 DIMMS now running slower at 2133 with bios 1.4 than the 2400mhz it ran at with 1.3 and all earlier bios versions?. I give zero veracity to the claim of 4 dimms running at 32000mhz. Especially since the claim was four 16GB dual ranked dimms on a Crosshair VI. I still doubt the Gigabyte users claim. It is totally inconsistent with what I have heard unless MSI has not developed their bios code properly. Something isn't right. I have seen or heard no such claims on the Titanium for 4 dimms. I would not be surprised if the claims on other boards are validated by others that MSI has once again fallen short with their bios team.

That's strange....
But exactly the reason why I'm still on beta bios 1.45. It works for me, 4 DIMMS at 2666mhz. The highest I got so far with tight timings.

Tried both and one at a time, also manually setting. Cant get above 2400

Flashing bios from 1.31 to 1.4 also resulted in less stable ram for me. I was running 2667 with my 2x8gb dual rank Crucial Ballistix Tactical with the 1.31 bios. Now with 1.4 I cannot get stable with any settings; tried manual, XMP, and Memory Try it. I had to lower down to 2400 to be stable.

I flashed to 1.40, and I got a WHEA error when running Cinebench with my 1700 at 3.7Ghz, 1.25V, when previously I never got WHEA errors. I upped the voltage a bit and the errors stopped.

Should I be enabling Cool and Quiet and CPU C6 State (I think that is what the setting is called)?

By slower , do you mean higher latency , lesser throughput , clockspeed?

Lower frequency doesn't always mean it's performing worse. Say AMD updated the microcode to allow for lower latency, that could make it more difficult to reach higher frequencies on the ram with the same measure of stability. At the same time, it may perform better. Tools like superpi or AIDA 64's cache and memory benchmark are good ways to measure this.

AMD is still working on a solution - it's not completely on MSI at the moment. Early on , AMD said it hoped to have most things ironed out by May on it's end - if they can keep their timetable, beyond that more of the burden will be on the motherboard manufacturers.

The fellows that are serious bencher's tend to use ASUS boards - look at the submission count for the CH 6 vs the Titanium on HWBOT . Those guys are the ones that are able to get what at the present time are "extreme results ( 4 dimms 3200mhz ram for example). This doesn't necessarily mean that the Titanium is less capable , rather that more capable overclockers are using the CH6.

It's a lot more complicated than it used to be "back in the day".

Even though there are ony a handful of actual IC's used, as Mega Man had mentioned there are differences in the actual DIMMs. The DIMM store tables with recommended settings but those are based on the Intel memory architecture. What's the difference? I cannot say definitively, but line impedance, frequency, voltage, and trace length all have an impact. Mismatched impedance will cause signal reflections, trace differences impact signal transit times, etc.

AMD is modifying their code to correct for differences between the given DIMM data and their actual requirements (at least that is my understand of this). The latest update may by misreading your DIMMs identity or have a mistake in it's "translation". The BIOS has more controls enabled that we can manually set to override some of these values, such as impedance, but without technical specs it is all guesswork and a PITA.

I would suggest that if a BIOS updates makes things *worse* for you, that you submit a service ticket to make the manufacturer aware. Don't expect a "fix" as a response, but at least they pass it along to the dev team to look into.
