Question Pc won't boot after RAM speed changes

[xbarnum96x]

Hi everyone , last night i tried to change the speed of my ram cause for some reason was locked very low , in doing so tho i risen the speed at a level that is in the possibility of the ram but not of the CPU , that lead my pc to not boot anymore, therefore i tried to clear the BIOS by removing the CMOS battery and shorting the CMOS pins (done it multiple times) and while the computer seems to act slightly different after reset , in the sense that the CPU error LED on the motherboard after reset stays on for a bit (about 15 seconds) before turning off , it still doesn't boot at all not even giving me the chance to enter the bios to reset to default settings , the motherboard seems to still recognise when a component isn't present , since the error LEDs turn on when something is removed , the only signs of life it gave were 2 error messages at screen telling me that the ram was slotted in the wrong slots ( while i was trying all slots ) and that the system was set up in gaming mode (that i have no clue what that would mean) , and couldn't replicate neither a second time tho, i don't really know what is the problem at this point , i also tried to use one monitor at the time with different cables, the computer was perfectly functional till yesterday and when trying to post all the lights turn on both the case and attached components. Is there something left to do , maybe another way to reset the BIOS to base settings without having to access it at monitor , or could it be that something got fried in the process ?

The components of the pc are as follows
MB: B450 Gaming Plus Max
CPU: AMD Ryzen 7 2700
GPU: Geforce GTX 1660 super
RAM: 2 sticks of corsair vengence DDR4 8+8 gb 3200MHZ
Power Supply: EVGA 550 b3

Thank you in advance for the help i hope i was clear enough in the question.

You know I'm surprised that your system isn't cooperating with you as that seems to be a stable system for 3200Mhz RAM. Strange............................Anyways, if this was in your post & I didn't read it please let me apologize in advance cuz these methods worked for me somehow. Back then, I had installed 3333Mhz RAM in my system and ran XMP with it and wouldn't boot; would just show RGB lights and that's it. I removed the farthest left channel slot and reset CMOS: it booted. That was one method I did. Another time was I installed a newer CPU with the same RAM and forgot to reset to default XMP and it wouldn't boot. So, I turned off the PC, unplugged it from the wall & let it sit for like an hour or 2; came back; held down the power button while it was OFF to drain anymore excess power from the remaining usage; plugged it back in; turned it on; BOOTED UP. Idk how I do it but it's just intuition and luck for me. It's like it KNOWS................................With you I'd say Remove your GPU and use IG if you can as it'll recognize your using a different integration for your display driver and will have to restart to rerecognize it so don't be alarmed if it turns on; TURNS OFF after. Worked for me when I wanted to use 64Gbs of 5200Mhz RAM with my current CPU a while ago.....................agane, LUCK.........................and food for thoughts............................

i'll try to mess around with the components than, thank you . But maybe i wasn't clear i'm sorry , i didn't upgrade the RAM i just changed the frequency through AMD ryzen master , that for what i know just goes to change the BIOS values for overclocking of the CPU and other things that are accessible trough BIOS , in this case i just changed the RAM frequency i moved it from the 1450MHZ that for some reason was set to , to 3000 that seemed to me resonable considered the RAM but i didn't informed myself that the CPU caps at 2700 or soo , sorry it wasn't clear in the first message

Hey there,

I'm not quite sure what the advice above related to, but it's a bit too much 'wing and a prayer' for me.

Do you still have the old ram? What happens if you put that back in? Have you tested each stick of ram individually? If not do that. It may be that one or more DIMMs are faulty or damaged.

When you did the reset CMOS, did you update the bios before this? Which bios is it running?

Test your mem outside of windows (if you can get to the bios or boot options) with memtest86+. This will test your ram to ensure it's running correctly. If it's not running corerctly, you will see loads of errors. This means the ram is faulty. Again, check with both DIMMs and then each one indivdually.

When you changed the mem speed manually, did you also put the mem voltage up to 1.35v? This is very important and if you didn't could be the reason it's not booting.

Were both sticks of ram from a kit? If you bought two different single sticks, this could also be the issue.

Yep, another AM4 system with Corsair Vengeance that won't run at rated speeds.

First, update your BIOS to the most recent available. Pull the RAM since it isn't needed and may be causing trouble and use M-FLASH. You'll need another computer to download the BIOS file and copy it on to a USB flash drive, ideally formatted FAT32.

Then try to boot the machine with a single stick of RAM. Once you get it running again we can try to make the RAM cooperate.

soo removing the GPU actually got me into the the BIOS somehow , after a couple of tries of resetting the CMOS with the GPU out it worked , i set back bios options to optimized default ones , but windows doesn't boot , i tried restoring the drive i'm booting from to a restore point i made yesterday but that didn't solve the problem , i guess is still a problem with the bios options that seem still a little weird to me ,

is it a problem with the options or do i have to reinstall windows ?

thank you NanoSuit3 for the intuition about removing the GPU , it actually worked , and thank you kira-faye for the more in dept solution i would have needed otherwise
