Hello all! I have proublem with G750JZ.

If i run films from my HDD i have random laggs every 10-40 minutes per 1-3 sec. If i install some games on HDD, when i playing in it, i have laggs too. If i use SSD, i haven't laggs. I started taskmanager and when lags situated i see 100% load on HDD for a few seconds.
I tried reinstall W 8.1, install new iamge W 8.1 MSDN, removed the factory partition HDD, and it doesn't help.
What could be the problem? Was anyone faced with similar problem?

DoomGart, HDD's suck - they sleep, they pause, they APM and used to AAM - replace it with an SSD and live lag free :)

But, until then you can use quiethdd to disable the effects of APM and AAM, stops the head parking noises but also stops the pause lags - like when loading textures in games from disk - and some video lags.

If you are getting video stuttering, and still get stuttering after installing / enabling quiethdd, look to increasing the priority to High of the process, and / or use Processor Affinity to set 1 Core exclusive to the video playback - some codec's try to multi-thread and don't pull it off convincingly.

Try quiethdd with these settings to stop the APM noise/lag.

https://sites.google.com/site/quiethdd/

Put these config lines in the quiethdd.ini file

FirstRun = 0
AC_APM_Value = 255
DC_APM_Value = 255
AC_AAM_Value = 254
DC_AAM_Value = 254
AAMEnabled = 1
APMEnabled = 1

Try different codec's too. I use the K-Lite Mega Codec Pack from free-codecs.com - read the installer options carefully to find the tools to change the priority of codecs to set "default" codes of your choice to test for best performance.

Thank you for tips, i'll try it. But, i have my home desctop PC, there are 1 SSD and two HDD (WD). And i don't have laggs in video/game in desctop PC.
Therefore, I think that such disk may be defective.

P.S. I've dealt with a lot of computers and laptops, and have not seen such delays. Hell, on a laptop for $ 2500 should still fly, why do I encounter so many deviations ?!

DoomGart, these lags are common with HDD's, your experience while broad and respectable, doesn't include everything in the universe :)

There are lots of times I have helped people here with HDD lags and quiethdd cures it, it is very common - search in the forums for quiethdd. And, for many years I have recommended other tools to adjust HDD APM/AAM, but they are too low level for most people, at least this one runs on Windows.

You encounter deviations because all complex systems have their own idiosyncratic behavior, and coming into it for the first time there will be specifics for which you have no previous experience, no matter how much experience you have, there is always more to learn, it is part of the joy of change through technological progress.

If you can mellow out, and kick back a bit, you will get more enjoyment out of your $2500 laptop. :)

Maybe you are right, and i must kick back a bit. In all cases, when i return my book from service, i'll try you tips with quiethdd, thanks in advance!

DoomGart, that's the spirit, everyone goes through this at some level with Asus / ROG frustrations, so you aren't alone... it isn't as bad as it seems at the time, and it gets better.

I will give you the big one now, Asus doesn't update drivers for hardware once they release newer models... you need to follow their new hardware releases to find the newest updates.

The G750JW/JX/JH download areas haven't had new updates for a while, at the time of this post the JM download area is where to get the latest Windows 8.1 updates, after the new G750 models after those are released then their download area will be the ones to watch. BIOS updates still happen in your model's support area, so still check there from time to time.

Here is the list of places I look for updates for my G750JH, so when you get your G750JZ back from RMA you can update all your drivers - the best way to get a stable fully functioning G750 is to update the drivers to the latest Windows 8.1 drivers.

G750 support areas - The JM download area has the latest of all the G750, with JS/JZ next, the G750JW/JX/JH are out of date:

Here are the Asus posted VGA drivers, it's better to get the latest from Nvidia - currently 340.52, except for the JM owners you probably want to keep using 332.60 to avoid random crashes - as reported by a lot of people.

That's about it as far as issues with Asus support. At least here in the US the laptop support group is great, and has quick turnaround for RMA's

What is your G750JZ RMA'd to fix?

They replaced subwoofer, but it doesn't help. Now the try to install original Windows 8.1 Image (i tried to install Win 8.1 MSDN Image), but i think it won't help them:)

Thank you for links, i don't know about situation with updates!

DoomGart, hopefully tuning the Subwoofer level, and the MaxxAudio Equilizer will give you good results when you get your G750JZ back from RMA. At least you know Asus replaced the subwoofer and tested it, so it's as good as it is going to get.

I would recommend getting a fast 16GB USB 3.0 flash drive to make an Asus Backtracker recovery bootable flash drive for future use - like upgrading your HDD to a SSD - or if you want to experiment with larger M.2 NGFF SSD's to replace your RAID0.

If you can share a link with Audio/Video material that is causing your sub to bottom out, I will see if I can get tuning settings that work. I don't get on here as much as I used to, but I will check in and look for your posts.

Unfortunately, i don't have RAID0 on my notebook. My subwoofer ckrak down, when i playing Divinity: Original Sin, or listen Rammsteon or Gregorian. I tried to decrease sab settings to 40-50 % and it was help me, but I thought it was - the fault, and passed the laptop to the service.
I read about MAXX +3 and think it can help me too.
