As far as I know, you're the first to have this issue, and if that's true, then I wouldn't count on a special bios update for it.
(Considering the fact it's likely an incompatability issue).

You also did not list your system specs nor information as to how you determined you have a high DPC Latency issue.

 
Its a dupe thread http://forums.evga.com/fb.ashx?m=1758484
 
Given his issues..
He should remove the X-Fi card and run a Driver Fusion pass for Creative drivers -and- disable his onboard sound. 
Could also be his SSD, he never did state he had done a secure erase...
Nor did he ever post his OS/driver install method...
 
 
 

i already have format C: and test with sp1 and chipset driver gtx 690 driver only but no improvement.
but the card in other PC from a friend and bbrother and its the same issue

when i switch back to my 580 there are no problems, the latency is always under 50 microseconds (in windows, in games always...) and no sound crackle. But with the GTX 690 the latency is in idle 400-800 microseconds in games 400 - 25000

Is your 2Tb WD hard drive a internal or a USB add-on?

You really need to go back to square one.
You missing something in either the OS install or in the config.
 
" i have all devices deaktivated in device manager"
This should NEVER be done.
-->Proper testing protocol is one device at a time and test, then re-enable and move to the next. 
 
Remove -all- attached devices except for your mouse, keyboard and monitor. No flash drives, headsets, webcams.. nothing else connected.
Remove your X-Fi sound card and all other installed cards except for your GTX 690
 
Secure Erase your SSD
*(go to the OCZ site and download the -correct- Secure erase Tool for your make/model/firmware of SSD)  
 
Quick format (do NOT full format) your SSD and re-install the OS
Do NOT allow Windows Update to install -any- hardware or device driver updates -PERIOD-
During this testing keep the internet -disconnected-
Install your MB drivers with the disk that came with it, only install the Chipset, LAN, SATA drivers. Do NOT install any monitoring or other "optional" drivers that are on the MB driver disk, and disable MB sound in BIOS and do not install the sound driver.
 
Do NOT install keyboard or mouse drivers, use only the Default drivers that Windows automatically installs.
 
Make -NO- OS settings changes whatsoever from defaults. None.
 
Install 306.23 Nvidia with a CUSTOM/Clean install
Leave the NVCP at defaults except to check the correct settings for the monitor (Screen res, refresh rate and bit depth) make no other changes.
 
This will give you a clean OS, MB driver and Videocard install to test with.
 
I suggest latency testing once -before- reconnecting to the internet and doing your Windows Updates.
Do NOT allow Windows to update -any- hardware or device drivers PERIOD. This setting can be found in the Windows update "change settings" panel.
 
After you have done your "Critical" and "Security" Updates -and- continued to return to the Windows Update page until no further such updates are available.
Then Test again.
 
Add in -any- programs, monitoring software or device/drivers ONE AT A TIME with a reboot after each install, and test.
 
In this manner you will find out what Device, Driver or Program install is causing your issue -or- if SSD controller stress was the cause.
 
Do NOT add in any device, driver or program install, without testing both before and after each one.
 
This is the only way you are going to find "whatever" is causing your problems.
 
Good luck
 
 
 
 
 
 
 

You appear to not understand the issues involved, nor proper testing protocol.
You do not even know how to properly uninstall a current Nvidia driverset
" i deinstalled driver in safe mode" is incorrect and should never be done.
-->One can only imagine what other mistakes you are making if you are unaware of how to use current Nvidia drivers properly.  
A GTX 690 is not a 580 or a 460 or a 590, and none of them have any existing known latency issues. Such issues are 100% user/config based 
 
I suggest you contact EVGA for a RMA and have them bench test the card.
-->This way you will know if its the card or your config.
 
Good luck    
 

fLaXi0n

the Nvidia support say to me should deinstall driver in safe mode with network

 
I fail to see why your having any driver issues at all, its not the Nvidia driver that is causing your problem.
 
Just RMA the card and have them bench test it.
-->If the card is defective, you will get a new one
If the card tests out ok, you will have to learn how to work the issue and find the cause.
*My personal opinion is that its probably some Asus software thats conflicting. Your motherboard has quite a bit of stuff from Virtu to Gpu tweakit to its overclocking/monitoring software that could cause this issue. That or the Creative drivers....
The list of things that could be the cause is quite extensive, you appear to not be aware of many of these.
 
Good luck.
 
 
 

 

i think the latency is so high because, Nvidias Frame Metering on GTX 690 :) otherwise please make a screen with gpu-z (GTX 690) and DPC Latency Checker and post it.
In the other thread from me is a person who has high latency too.
In 2 different computers who i tested it, its the same ONLY WHEN GTX 690 is installed. (No issues with GTX 560, GTX 580 and GTX 260).
I do not like to let kidding me .
I payed 970€ for a mistake from nvidia, where I have to live with????? OMG
U have to test it urself, then we can talk again, sorry that I'm so pissed. :(  and sorry for my english
 

dont use dpc latency checker, it has know issue with  win7 and dont show latency right (basically show latency incorrect), use Latency monitor its much more accurate and more detailed . dpc checker show much higher latency compared to latmon and most people agree not to use dpc checker on win7 and above. because of the fact it shows the latency with incorrect values.

ok Latencymon shows nvlddmkm.sys this is the nvidia driver

306.23 drivers normally are in the 200-500 dpc range a lot people any higher  would be deemed  questionable if its spiking to like 1k+ there is something wrong with either cards or some driver are conflicting and causing the issue. Run lat mon for like 30 min or so with bunch stuff running A game,Media player running music and maybe browser running too.
 
  Also Realtek drivers are know to cause issue with dpc, alot people fix that by using .53 drivers
 
 
  
  This is with Swtor Running, Winamp Streaming music, and a Firefox open. Note I am also running Hpet 64bit in bios and Hpet enabled in Win7 with Setplatformclock set to true
 

tell me more!
