[SOLVED] Intel I5 8400 is not performing as it should.

Sounds like boot partition is on the HDD and is giving you a confusing error message. Try reinstall Windows. Turbo should work then.

Well to start, Userbench is reporting turbo below base clock of 2.5 when it should be closer to 4GHz. Check temps and frequency with Coretemp under load playing a game or stress testing. Userbench can be inaccurate so do check.

Another issue is lack of ram. 8GB can be fine sometimes but Win 10 can consume quite a bit for itself, onwards of 3GB so out of 8, that doesn't really leave much for more ram
hungry applications or games. In which case, 16GB ram is recommended.

I do have 16 GB of ram. I just forgot to add it to the PC partpickerlist. I have 2x 4GB and 1x 8 GB which is probably a very weird weird to do it but I recently upgraded to 16 GB so I went with the most cost effective solution,

Here are the CPU temp stats while playing a game, still stuck at 2.5 it seems.

Download CPU-Z and on the memory tab check the 'Channels#'

Temps are fine, nothing to prevent turbo. That could be a Bios setting or Windows. Was anything changed in Bios or Windows power plans?

Maybe try reset Bios to defaults and run Windows with high performance plan.

Regarding memory, see example for dual channel with three sticks.

https://www.intel.com.au/content/www/au/en/support/articles/000005657/boards-and-kits.html#dual

Very first slot, closest to cpu, has the 8GB and 2nd and 4th slot populated by the 4GBs.

You have enough ram, not all in dual channel but good enough. Need to find out why turbo isn't reaching higher.

Tried plugging in the ram like you said but then the DRAM light comes on on my motherboard and there is no video output.

Edit: Seems that the slot closest to my motherboard is blocked by my cpu cooler unfortunately. So I can't use that one.

I'm having some problems with my CPU bottlenecking in games it really shouldn't. When I went and test it it seemed that my CPU is really underperforming. Any idea how that might come?

Just to make the pot a little smaller remove the 8GB stick of ram and fit the 2x4GB sticks in a2+b2.
Here's the manual which shows a pic of which slots to use.

Rerun UBM and post a link to the results.

Heatsink isn't that large to block slots. Maybe fan is in the way but you can raise that up a few heatsink fins to make room for ram if case side panel has enough clearance to close.

Ah yeah you're right. Fixed that now thanks! I have also reset the BIOS but that didn't make a difference sadly.

Ok so lets assume your cpu is now turboing properly and your ram is running semi dual but with 16GB, what game are you having trouble with? Keep in mind, 8400 6core, + 1060, is an ok combo but what games are you expecting more in?

On FiveM (GTA but with mods) I usually get around 30-40 fps and CPU usage jumps to 100% and then it really starts going up and down.

Not familiar with Gta5 mods sorry or how cpu intensive they are. Is your cpu turbo sorted out now? Because your latest userbench link doesn't look like it.
Click to expand...
No the turbo is still busted it seems. Gta with mods is a really CPU intensive game. I'll try updating my bios too

Download and run ThrottleStop.

https://www.techpowerup.com/download/techpowerup-throttlestop/

Turn on the Log File option and go play a game for at least 15 minutes. When finished testing, exit your game and then exit ThrottleStop so it can finalize the log file. The log of your CPU performance will be in your ThrottleStop / Logs folder. Attach a log file to your next post.

Also show me some screenshots of the main ThrottleStop window, the FIVR window and the TPL window.

After doing the above, play your gta5 mod and run Coretemp. Check what that reports cpu speed at and temperature.

Turbo is an automatic feature so it's either turned off in Bios (shouldn't be at default settings) or it's getting too hot and cpu is preventing turbo to save itself.
