Getting continous drop-outs. DPC Latency showing massive red!

post #1 of 13
Thread Starter 
Hi all,
Hopefully with the help of you I can figure out which driver is causing my system to have massive drop-outs. I am getting constant red bars on the DPC Latency checker. I have done the following:
- disabled wifi card
- disabled sound device
- rolled back my GPU drivers

Still getting these massive drop-outs and its starting to worry me. The most recent upgrade I did to the PC was add a Plextor PCI-e SSD.

Any thoughts?

Cheers

This version of dpc latency checker does not work corectly with windows 10. Sorry i don't remeber which one does work because i am on my mobile. Just type windows 10 dpc latency and google it.

Welcome to NV driver lag smile.gif

Also try this:
http://www.resplendence.com/latencymon

If you want low latency then disable Hyperthreading and delete NV driver.
(i know you need the driver but have a look how much latency is reduced without one)

Edit:
CPU throttling introduces latency aswell.
In power options you can set minimal CPU state, i have mine clock down to 3200mhz instead of 800mhz and it improves latency alot.

I get the same results with the LatencyMon that works with windows10. What is NV driver?

Nvidia Driver.
Un-instal the driver and see how much latency drops.

In BIOS disable HPET and Hyperthreading and see if latency drops.

You can re-enable Hyperthreading and install then NV driver again later, just see if it lowers latency or not.

Also dont forget to adjust power options to make your CPU throttle higher then 800mhz.

How am I supposed to do that and not loose my video? how about when gaming, don't i need the nv driver for all that?

I don't really know much about DPC latency.
But are you only able to tell you are getting latency spikes because of the program, or are you actually noticing it while using your computer?

I was noticing it while watching a TV show or streaming music off Spotify. I haven't noticed it in a couple days tho.

Just to see if its indeed the driver that give's you a high latency.
I said to re-install after you tested it wink.gif

Have you tryed the other things i mentioned ?

I just disabled Hyperthreading and so far I have not gotten any dropouts per LatencyMon. Hmmm, interesting. Any thoughts? I have the CPU minimum power state set to 75% at the moment.
