Without reading through the whole four pages, I would like to suggest AMD Radeon RAM Kits. Since the memory controller is within the (AMD) CPU, why not use AMD RAM?
I am aware that most QVLs are dated and they surely concentrate these tests to the Intel field, but even though Radeon kits were not in those lists, I never had problems.
 
A general recommendation is to check the "sub-timings". For example if a kit has CL10-11-11-30, by sub-timings I mean all the others.
I often see mainboards not reading out SPD correctly. Not even if XMP or AMP is being used! A great tool to read nearly all the timings is AIDA64. Even AMD Overdrive will do most of them. These sub-timings tend to be most important for long-time stability when running at specification limits.
 
And remember using memory above 2133 MHz (theoretically 2200 MHz) is no good at AM3(+). OC'ing the CPU-NB can be an incidious matter and has nearly no performance impact, especially on memory side.

Thank you for posting the pics.

If you look at the recorded clock speeds, you'll see a big difference there too. I wouldn't expect changing RAM voltage to cause you CPU to run at 4 GHz most of the time. It's likely due to your computer doing something that prevents it from accessing those lower performance states.

Hmm. Your AUXTIN temperature seems a bit high if we assume that it's the PSU's temperature sensor and that it's working properly. Are you able to check if the PSU fan is working and if yes, is the air that it's blowing out warm?

P.S. CPU-Z, HWM and FSTREAM info will do just fine, at least for now.

No, I don't. But maybe PetrolHead has.

Let us know how it goes.

If it doesn't behave setting them via XMP we can take a stab at entering the specs in manually.

Have a good day at work

Hi Wardog,
 
Ok thank you, I'll follow the procedure this evening and will keep you posted.
 
 
Do you need something else than the standard CPUZ, HWM & FStream printscreens?

And check that DRAM Voltage is at 1.65v, which is proper for these sticks at 1600.

Core voltage looks lots better. Reasonable.

I believe I'm going to lead you straight here ...... I'm using the online manual, sigh

First, lets reset your BIOS back to all defaults...
BIOS > Exit tab > choose "Load UEFI Defaults" save and reboot right back into the BIOS, then the Exit tab again, then "Save Changes and Exit, then right back into the BIOS. I know, PITA

OK, let's set the sticks to their 1600Mhz XMP Profile.

BIOS > OC Tweaker tab > and here on your board I believe you want to select "DRAM Timing Configuration" , and you should now be presented with an option to change to an XMP Profile.

That's all you need to do is select an XMP Profile, the save and reboot. Don't muss nor fuss with anything else at this point. After selecting the XMP and rebooting go right back into the BIOS to check that your sticks are running at 1600.

Again, doing this in a forum sucks, post back please what you find.


edit: OK, not PK

Guys,
 
 
I wanted to check again the HWMonitor and I'm rather surprised the CPU Voltage is completely different than the one I experienced when the Ram was at 1.65V
 
 
 
While before it was oscillating between 0.88 and 1.408 (most of the time it was @ 0.88), now the spread between the Min the Max is very tight.
 
Can this be related to the fact the RAM voltage has been changed?

Ok, I set the RAM to 1.5V through the BIOS and it's confirmed by FStream.

It's DDR memory. Dual Data Rate, so dual of 800 is 1600. 1600/800

That it shows 1333/667 is again the JEDEC Default that it automatically sets to. We'll get to changing this in a sec .....

Um, your Core Voltage is terribly high for the Clock Speed displayed. Too high!

Have you been in the BIOS making changes, and the truth here please, as your answer matters greatly and much that will follow is dependent on the answer you give.
 
As said never touched anything. Everything was set on Auto on OC Tweaker. The only non Auto thing is RAM voltage set @ 1.5V instead of Auto (1.65V).
 
Am I meant to do anything with the Core Voltage?

Hello PetrolHead,

Thank you for the screenshots. Your RAM timing values seem to be okay, but for some reason your RAM voltage is higher than it's supposed to be for that speed. You might want to set it to 1.5 V at first to make sure it's not causing the issues you're experiencing.
 
Done that through the Bios (1.65V was actually the voltage from the Auto setting)

The core voltage displayed by CPU-Z does also seem a bit high. It should be closer to 1.375 V at 4 GHz. F-Stream does show it to be 1.376 V, so the question is which one is closer to the truth? If you run, say, HWMonitor, how much does the voltage fluctuate?
 
 
So here are the test HWMonitor results after about 5minutes

I never touched anything, neither in the Bios or in FStream :s
 
I will make the hwmonitor test in a few moments, about 30-45m. Need to put the kids at sleep!
