Good afternoon!

First of all, I want to introduce myself in the new forum.
I am Hugo, of Portgual. : D

With the config I have, it is stable at 45.
It follows in the bios:
AI Overclock Tuner - Manual
1 - Core Ratio Limit - 45
2 - Core Ratio Limit - 45
3 - Core Ratio Limit - 45
4 - Core Ratio Limit - 45
CPU Core Voltage - Manual Mode - 1.325v
DRAM Voltage - 1.65000v
CPU Spread Spectrum - Disabled
Timings - 11-11-11-28
VRM Spread Spectrum - Disabled
SpeedStep - Disabled
Intel Adaptive Thermal Monitor - Disabled
Dynamic Storage Accelerator - Enabled
SpeedStep - Disabled
CPU C-States - Disabled
PCI-E Speed - Gen2
PCI-EX16_1 Link Speed - Gen3
ASMedia Storage Controller (SATA6G_E12) - Disabled
Anti-Surge Support - Disabled
Everything else is in Optimal Default

Given this OC, should change some parameter? This is because there are certain opcções, which should not be in self.
In the bios put the 45x, but when it is in full, go to the 46x, as you can see in the image.

This is due to the clock bus, move to the correct 102Mhz? I then switch from auto to 100Mhz?
Given that the CPU this stable, wanted to stay with a lights, for the memories.
Should I change the frequency of them, as they can go to 2400MHz? There currently are 800, as you can see in the image.

Another question I have is how do I decipher the voltages that are here, representing the bios voltages?

It has different names, and I'm not sure what matches what.
In System Agent Offset noticed that gives + 0.102v, should keep or change to another value?
Thank you!

Hello Nightwalker

Welcome to the ROG forum !

You overclock your pc like I do in manual mode and it all looks good.

If your ram is a 2400MHz kit set the ai overclock tuner to XMP this will set your ram at its rated speed, timings and voltage. The main voltage to be concerned with is the cpu core voltage, that is shown in HWMonitor as vcore.

You can enable anti surge support.

If you want your cpu to throttle down speed and voltage when at idle you can set the cpu core voltage to adaptive and enter in 1.325v in "Additional Turbo Mode". Make sure the windows power plan is set to balanced.

Raising the BCLK (bus speed) will raise the cpu and ram speed so keep that at 100.0.

I tried to cover what you asked if I missed something please let me know. 🙂

Before too, thanks for answers Nate 152!

Yes, we answer questions, but I still have some doubts.
It's not even necessary to change most any parameters? I want it as well, 24h / 7 days! I see a lot of people talking about LLC, VCCIN, etc ...
For the adaptive, methoxy "+" or "-"?
Yes, I know that to raise the BCLK, will raise the cpu and memories. The problem is that in full load, go to the 102, I do not know why. But I will be fixed in 100.

PS: By the way, my memories are as follows:

GSkill TridentX 16GB 4x 4GB DDR3 2400MHz PC3-19200 CL9 - F3-2400C9Q-16GTXD

You can set LLC to 4 or 5 (medium) anymore than that and it will overshoot the cpu voltage you set.

I'm not sure why the BCLK would raise on its own to 102 normally it holds at what you set it to.

You could try resetting to defaults then enable XMP, sync all cores and set the cpu core ratio to 45 and the cpu core voltage to 1.325, F10 and Enter and see how it acts.

Since you are overclocking in manual mode you could try setting the windows power plan to high performance and see if the BCLK holds at 100.

Hello Nate!

I did what you said. Put LLC - Level 5, XMP (Profile 1).
Took off smoothly, but ran the IETU, soon gave error.
Then switched to manual again, and put the memories the 2400MHz and timings to 9-11-11, the rest left in default. I ran again the IETU and RealBench for 15 minutes and passed without problems. Which leads me to believe that is a parameter that was on auto, which causes the error. Is the command rate? Relaticamente the BCLK definitely HWiNFO64 is a reading error, because the CPU-Z keeps us always 4500Mhz.

Let the command rate at 2 and it's fine to set your ram manually as you've done, be sure to set the Dram voltage to 1.65v. If all is working for you it sounds like your ram is good to go.

You can check in the bios what the vccio voltage and cpu system agent voltage is drawing and give those voltages another .01v - 02v and run IETU again.

If this doesn't help your cpu may need a little more vcore.

Hello Nate.

I apologize only answer now.
After all, this does not seem very stable. Just take a bluescreen.
Here's a pic:


What could it have been? Anyway, I went to 1.330v in vcore.
Will it or memories? I noticed also that the board has overvoltage.
In the DRAM Voltage, I 1.6500v but goes to the 1.662v. Does crashes by overheating? Descend until even in 1.6500v?
After discovering the problem with your help, I'll do what you said in the last post. Just I do not quite understand the last part. "VCCIO voltage and cpu system agent voltage." Can you be more explicit please?

Thank you

You're welcome

It's looking like your cpu needs a little more vcore, your temps look good so try up to 1.35v - 1.40v. Start at 1.35v and add .01v until the crashing stops or temps get too high.

Your ram at 1.65v and fluctuating to 1.662v is fine, your ram isn't over heating.

OK! I put the 1.330v for now. Because it took two days to have error. So I think it is not necessary to go soon to the 1.350v. But correct me if I'm wrong! If you do not mind, can you explain better what you said to do?

Yes

If you still get bluescreens or crashing raise the cpu core voltage to 1.35v and run a stress test, if it still crashes try 1.36v and test again, if it still crashes try 1.37v and test again and so on up to 1.40v until the crashing stops.

Keep an eye on your temps.
