Hmmm, in mulling this over I'm wondering if the XMP Profile on your admittedly older sticks conform to the minimum XMP 1.2 Profiles your board allows.
YEA! Screenshots .... Please. Those will speak volumes to all this. |

Haha, if that's the problem, that wouldn't be just nice, that would be great! I'll provide you the printscreens around 21h00 / 22h00! Thank you for your help!

Dear Wardog, Petrolhead, Here are the printscreens... It looks there is something strange about the RAM. Should be a 1600mhz like it is mentionned in the "part number" of the SPD section. It is stated as 1333mhz in the BIOS and here in CPUZ I see max bandwith 667Mhz... Is this normal? Anyway I let you check all the things you asked Can you see the printscreens?

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. |

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. 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?

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!

Hello PetrolHead,
Done that through the Bios (1.65V was actually the voltage from the Auto setting)

Ok, I set the RAM to 1.5V through the BIOS and it's confirmed by FStream.
Do you want me to set the RAM at 1600mhz in the BIOS? If so, shouldn't it need to go back at 1.65V instead of staying at 1.5V?
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?

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?

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 Edited by wardog - 07 Jan 2016 at 7:03am |
