G75VW with GTX 660M poor performance


Dartel

Recommended Posts

Hi

I have recently purchased a used ASUS G75VW with Nvidia GTX 660M. GPU-z reports PCI-E 2.0X16@X16 2.0

other utility reported PCI-E 3.0x16@x16 2.0. There is definately some performance issue.

Any help much appreciated. Also the keyboard backlite does not work but I am not too concerned about it.

Don't flash your bios unless you have to. One small mistake and you have a bricked mobo. Try the lastest nvidia drivers and see if that helps. Even try the beta drivers if the WHQL drivers don't. Beta drivers just mean that they haven't sent them to Microsoft to be "Approved."

I had a ton of issues when I bought my G75 last year. It took almost a full year before most of the problems were fully worked out. For instance my touchpad has finally started working this past week reliably. I had major sound issues which required a couple new versions of drivers before most of the problems were resolved. Now I have an issue with the speakers and headphones working together or not working at all after a fresh install of Windows 7.

My recommendation is to update your bios to the latest version. This will fix the issue with booting from sleep mode if you are running an older bios. Install a fresh copy of Windows and install drivers and utilities from scratch. Be sure to check the official ROG asus forum for the latest working audio driver. The Via chipset they used in this model was not the best but the latest driver seems to have fixed most of the sound issues. Other than the problems I had to sift through and fix I have been satisfied with Asus and even this model. I will be sticking with it for another year before I upgrade. I am hoping for a more advanced processor in the next one. Maybe someday we will get the hexacore without having to get a tombstone sized box.

I'm having similar issues with my G75-VW....I got it at the beginning of this year, not for gaming but rather development, running ubuntu inside of a VMware workstation with all other kinds of tasks going on in the host and guest OS...and lots of lag. It shouldn't be running as slow as it has been considering the specs, so I will go with your guys' suggestions, updating the GFX card drivers and the bios if possible before trying to overclock this badboy. Appreciate the support and I hope nobody minds me posting in this thread with the same issues as the OP, I figured it'd be better not to open a new one :)

hey OP, first make sure your laptop is plugged in with the original powercord, second, go into control panel and make sure your power options are set to high performance, if not it will clock down the cpu and pci express in order to save power, i have noticed that you have to set custom power profiles for things to work properly, after that i never had an issue, hope this helps
