My PC is ignoring any changes I make in the BIOS to overclock my CPU

[Arson]

CPU: i3 8350K and i9 9900KF

Cooler: Corsair H100i v2

Motherboard: Gigabyte Z370P D3

RAM: 32GB Corsair Vengeance LPX 3200MHz (2 kits of 2x8GB sticks)

GPU: ROG Strix Vega 56

PSU: EVGA G2 750W 80+ Gold

Boot Drive: Western Digital WDS500G2B0B 500GB M.2

 

Recently I got a new CPU (9900KF) to replace my old 8350K. I had a stable 5GHz OC on the 8350K with no issues with my BIOS changes being ignored. Before I upgraded my CPU I updated the motherboards BIOS to the latest version (F15b) just in preperation for the new CPU as I only like to do it when I'm replacing hardware. My overclock was still fine with the new BIOS with the 8350K and so I used the system as it was while I waited for the 9900KF to be delivered. I swapped the CPU and everything seemed fine until I tried to overclock it and noticed that no matter what BIOS settings I changed the CPU stayed with its standard settings. I then installed Intel XTU to see if I could overclock it that way, which worked but was not ideal so I continued trying to overclock in the bios with the settings I found to be stable in XTU. Does anyone have any idea on why this may be the case?? And also how I might fix it so I can overclock my 9900KF please? Thank you in advance.

Did you try and clear the cmos during the cpu swap? If not, now is a good time. 

 

Jump the cmos jumper 10 seconds...

Or

Remove the battery, power off the PSU and wait 10 minutes.

You can hit the power button to relieve caps.

Assemble the battery and switch on the PSU.

 

Good luck!

You’re right he needs to do a cmos reset but you’re instructions are terrible.

Shorting cmos clear pins as per the manual often doesn’t work so the best way is to remove the cmos battery, turn mains power off from your motherboard AND monitor then hold the power button on your case for 10-15 seconds. You may see motherboard LEDs blink on for a second as the capacitors drain. It’s very rare you need to wait more than 10 seconds for a modern system to drain so don’t worry about exact timing unless it doesn’t work first time. 

 

Any overclocker would recognise your issue which occurs after a failed overclock so you obviously need a cmos reset and potentially a bios update. Anyway hope that helps.

The only difference from removing the battery and using the jumpers is it clears the time and passwords. nothing more.

 

No, you don't have to hold the power button. That's not even in any manual anywhere. That's just a "trick" and takes ONE second to relieve caps. lol. (Why you see the diag leds flicker once)....

 

Not sure if he hot swapped chips and didn't clear cmos after the flash or bad OC. Typically after a bad OC, you can still save settings... because they remain saved. 

 

By most well written manuals that I've read, 5-10 minutes battery removed, 5-10 seconds on the jumper. removing the battery requires the PSU switched off. There's little more instructions for clearing a cmos. Some boards, like mine has a nifty clear cmos button on the back panel. Makes it super simple.

You're digging a big hole pal. Paragraph 2 and 4 directly contradict each other and paragraphs 1&3 are completely false. I don't think you've completed a cmos reset as resetting the bios(its actually uefi but meh) time is absolutely reset after a cmos reset. Generally hobbyist market boards can have there bios password reset with a cmos reset but its important to be aware many oem systems passoword systems survive a cmos reset and the only way to get around this is reprogrammig the chip.

 

ALSO PLEASE STOP ARGUING YOU ARE CLEARLY ONE OF THOSE PEOPLE WHO CANT BE WRONG.

So far, any time I've suggested a way to clear a cmos, haven't had a problem until you stepped into the forum.... So I'm not entirely sure about your claims here. 

 

I can agree that some bios's differ than others, UEFI and legacy, the effects of going bad batteries, some boards work find and great without a battery and some don't. On and on so forth ect ect.

 

And then we are mentioning OEM systems when clearly we are talking about (staying on topic here) a Gigabyte Z370P D3 which is clearly posted in the spec list at the OP. 

 

So, I'll just come out and ask what's your beef with me? You seem to have the only complaint so far. I've been polite with you so far..... What gives?

I've encountered several instances of the BIOS not saving with my Gigabyte Z390 Aorus Master MoBo.

Have you tried going into the BIOS, using the Restore to Default, Save changes and REBOOT. Then go back into an make the changes.

 

This is when I was messing around with my DRAM overclocking / timings, though.

I was frequently making small changes, PC crashing, going back into BIOS, etc.

I did clear the CMOS during the switch but to be thorough I have done it again and it did not fix the issues I have been having, thank you for your suggestion though!

I tried this today and it did not seem to fix my issue, thank you for your suggestion!

Clear cmos and try to reflash the bios (same revision is fine) and see if that does the trick.

P sure my msi b350 bios does that too. Sometimes.  So this is probably spot on.
