Overclock QX9775 processors on Intel D5400XS (Skulltrail) motherboard

[RedKiter]

Good evening, this is my first post. I would like to overclock the Intel QX9775 Extreme processors a little. They come with unlocked multipliers as standard. I have no idea and it's my first overclock. I have had this PC since 2008. I don't know which parameters to touch, but I am interested in not touching the Ram or anything else that is not the processors.

I tried to increase the multiplier from the standard 8 to 9 and it went from 3.20GHz to 3.60GHz. I ran Aida64 and it doesn't crash and barely reaches over 58º on the CPU. I tried 10 for the multiplier (4GHz) and immediately the blue screen appears.

I have read that for this you have to increase the voltage, but there are several parameters in the BIOS and I get lost there, and just in case, given my lack of knowledge on the subject, I have come this far.

If necessary, I will take a couple of photos in the BIOS and some guru of the subject will help me please, goodbye.

Hello and welcome. I assume you will have a good heatsink.

If you have touched the multiplier you are supposed to already know the theory. Have you touched the FSB? It is advisable to touch it in addition to the multiplier and play with it. The voltage depends on that particular micro but normally you have to try to raise it from 0.005 to 0.005, to be careful.

Best regards

Hello, a question. If I raise the front bus, everything will be raised, right?

If that's the case, I'm only interested in raising the processor. The ram on my motherboard is FB-DIMM and it gets very hot. Also, my graphics cards, when I use them to play, go over 70°.

I put Noctua heatsinks on the processors when I bought them and they never go over 55°.

My question is. Is there any way to raise the processor to 4GHz while leaving the other components intact?

More data. My frequency appears at 400mhz
Front bus 1.2v
MHC (I imagine northbridge) 1.25v
CPU0 voltage default (1.250v)
CPU1 voltage default (1.250v)

Some voltage offset in disabled

And the multiplier 8 now modified to 9, if I put 10 I get a blue screen with aida64

For a multiplier, it will cost you more to be stable, the technique that suits you best is to raise the FSB and lower the multiplier, blocking the PCIe so that it doesn't go up any more. What you can do is touch the divider so that the memories don't go up so much with the FSB.

I enter the bios and this appears:

I go to the performance tab:

I enter the first line where it marks the processor parameters

With the multiplier at 8, the voltages below in both Current and Default are at 1.250V, now that it is at multiplier 9, the "Current voltage marks 1.300V

That's all I did, as I have no idea, can you tell me what else I need to touch there?

[Sylver]

I can only tell you the theory, I do not have or have never had that processor and I do not know what the optimal values are to get the best overclock. What I do know is that if you do not want to touch the FSB you are going to complicate things a lot. The best processors for overclocking by touching only the multiplier are the Sandy, Ivy and similar recent ones from Intel, the versions with unlocked multiplier, which with just raising the multiplier easily exceed 4Ghz stable air-cooled.

1,4v for 4GHz, too much voltage. It makes no sense to not want to touch base clock and go overboard with the voltage, if you want to run via multiplier you will have 3,6GHz. To touch the voltage change from default to manual and to go above 3,6GHz touch base clock (Performance - Host Clock Frequency) but, don't think that this board goes up as much as a P45, if you want to get close to 4GHz go with a multi of 9.

Editing: By the way what power supply do you have?

Ok, so, to do it right, exactly what do I have to do, beginner's manual. :love:
