BSOD KMode Exception Not Handled? HELP!!

[Ashleyjames98]

Hi,

So as the post title implies, I'm getting the Blue Screen of Death with the error code (KMode Exception Not Handled.)
I have looked into this online and I struggle to get a definitive answer. Before anybody asks, yes I have made upgrades, but only to the RAM (from 16gb 3000Mhz to 24gb 3000Mhz) yet I can't see this being the issue. This always happens when I'm playing games; it hasn't happened when using browsers, File Explorer etc.

If anyone has any idea why this is happening, please let me know,
Thanks

The KMODE_EXCEPTION_NOT_HANDLED error means that a process running in kernel mode (that is the privileged mode in which the Windows kernel runs) has generated an exception (that's something that shouldn't have happened) and there was no specific error handler to deal with that exception - so the system BSODs.

The most likely cause is a driver, because drivers run in kernel mode and yet they are rarely written by Microsoft themselves. Since it happens in games only it's more than likely your graphics card driver. These drivers are a fairly common cause of BSODs in any case.

I would download DDU and use that to uninstall all previous versions of your graphics driver, then download and install the latest driver for your card. If that doesn't work, use DDU again to remove that driver and then download the version immediately previous and try that.

It is possible that your additional RAM could be the cause. Are you quite certain that the new RAM you bought is exactly the same as your existing RAM, and by that I mean exactly the same part number. All your RAM cards must be identical with exactly the same timings etc. or you will have issues.

24GB of RAM suggests you have 3 RAM sticks? RAM should be installed in pairs unless it's a 3 channel motherboard (rare).

Is this a PCS system?

It's true that you won't get dual channel across 3 RAM cards but it still works perfectly well.

Hi,

Yes, it's a PCS build except for the RAM in which I ordered and installed. The first two RAM upgrades worked without a hitch. The third stick seems to be causing problems however. Could the third stick be faulty?

*UPDATE*

Since the BSOD had stopped temporarily, I ran Windows Memory Diagnostic and it says ' Hardware problems were detected.' Beings as this is a memory diagnostic, would this further support the theory of a bad RAM stick? Any answers would be appreciated.

Windows memory diagnostic is not a great tool, but yes, would point towards a bad RAM stick.

Better to use memtest86 from here and create a bootable usb:

Hi,

So after disabling XMP, taking out the module, reinserting it and re-enabling XMP, the system started without a hitch (Normally it'd start with three short beeps, indicating a fault with memory) however running a diagnostic says otherwise.
Any other ideas?

Thanks in advance

The usual process is:

Take out all RAM except 1 stick

Run memtest. Note the results.

Remove the RAM and put another stick into the same slot, and run memtest again

Identify any faulty sticks.

If all sticks are faulty, repeat the process with a different slot for the RAM.

Any incompatibility whatsoever with that RAM setup is going to cause problems. Its never recommended to fill 3 slots. RAM is always recommended to be added in pairs with a matching capacity across the board.

If I were in your shoes I would either stick with 16GB of RAM and return/resell the 3rd stick.... or purchase a 4th to go with the far more common 32GB of RAM.

There's a reason multiples of 3 aren't available on the configurations. You're running a W12 engine on 9 cylinders.

Again, I can't fully agree with this.

For maximum performance you definitely want matched pairs of RAM to take advantage of dual channel bandwidth, but for some the size of installed RAM is more important that getting dual channel across all of it. PCS (or rather Clevo) certainly used to make laptops with 3 RAM slots, my Optimus IV has only three slots.

It is absolutely NOT true that filling 3 RAM slots will cause problems, as long as they are the same type of RAM they will work perfectly well together, you just won't get dual channel bandwidth across all of it. My Optimus IV has 12GB of installed RAM and it runs like a dream, even when I load up that RAM.

I think we would better serve the users on here by making the relative advantages/disadvantages of any given configuration clear rather than claiming that a less than perfect config performance-wise 'will cause problems'.

It certainly seems that the OP has a faulty RAM stick - or the new RAM stick is not compatible with the existing two. Personally I don't think it necessary to run Memtest, if the Windows Memory Diagnostic is reporting errors then there is certainly a RAM problem. Testing each RAM stick on its own is certainly the way forward to find out which one is faulty. Then the OP should replace it.

Hold on.... where did I state that it will cause problems to use 3 sticks? I said any incompatibility will cause issues, which is absolutely accurate.

I merely stated that it's not recommended and there's a reason why it's not available as an option in the configurators, as it's a pain to match properly (RAM is mostly sold in pairs). Even with the 3 slot option I'm almost positive that you could only select the RAM in pairs.

I'm not sure why you have a bee in your bonnet with me about this but you have misinterpreted just about every point I made in my post. I don't mind a healthy debate but at least understand what I'm putting out there before berating me.
