Updated: NVIDIA 196.21 WHQL Driver Disables Users to Overclock

Update:

NVIDIA has told TomsHardware that the driver’s behavior with overclocking tools is indeed a software bug and they’re working on an updated driver package to fix it.

The folks at EVGA also act quickly by updating their utility to version 1.9.1, and you may click here to download.

Yesterday NVIDIA updated its GeForce/ION driver to 196.21 WHQL version which includes SLI and multi-GPU support for many new gaming titles as well as some bug fixes, but several users have found that after upgrade they’re unable to overclock any more.

Expreview did a small test to check out if it’s true. We run the test with Galaxy GeForce GT240 under Windows 7 64-bit operating system, and used the following four popular overclocking utilities to see what would happen.

* RivaTuner V2.24C

* EVGA Precision V1.9.0

* Galaxy MagicPanel HD

* MSI AfterBurner V1.5.0 Beta 5

RivaTuner V2.24C

As you can see, RivaTuner V2.24C just allowed us to tweak GPU clock and memory clock, while oddly, the shader clock just disappeared.

EVGA Precision V1.9.0

We had the same problem with the newly released EVGA Precision V1.9.0 – the shader clock can’t be tweaked either.

Galaxy MagicPanel HD

Things get even worse with MagicPanel HD – none of the core/shader/memory clock can be tweaked.

MSI AfterBurner V1.5.0 Beta 5

MSI AfterBurner V1.5.0 Beta 5 was the only software which “survived” during our test – everything works great.

Why the new driver won’t allow overclocking? The only reason that we could think of is the new driver was specially optimized for NVIDIA’s upcoming Fermi-based VGA cards, making it working against the current overclocking software.

If you feel the need to overclock your NVIDIA cards, we suggest you to stick with an earlier driver version or use the latest AfterBurner utility until the problem is resolved.

    Son of a B! They must really be having problems with those Fermi cards if they can’t overclock them AT ALL!

    EVGA Precision 1.9.1 works without problems :)

    Version History:
    EVGA Precision v1.9.1 (01-21-2010)
    Added workaround for overclocking bug of ForceWare 196.21. Please take a note that the workaround is applied only to 196.00 – 196.21 driver versions range in order to ensure compatibility with future fixed NVIDIA drivers.

    I don’t overclock anyway. I get massive tearing and damage to my gpu due to heat.

    I have something a lot better for you. Don’t use OC software, just export your bios from graphic card, edit clocks, fan speed, anything you want, then save it, make bootable pendrive or something and flash card. Voila, u got self-OCed card x]
    It’s 100% safe, did that on many cards, many times (tested OC, FANs, Boot String)
    Check out this package:
    http://www.mediafire.com/?izajnz0veyk
    There u have all tools needed to do whole, easy operation. (unpack WIN98 folder and choose it in ‘HP USB Disk Storage Format Tool’ as custom DOS files, use FAT32 if FAT don’t work.

    Oh, after booting pendrive, type:
    nvflash.exe YOURNEWBIOSNAME.rom
    Of course u must copy nvflash and other one .exe file from nvidia flasher directory to bootable pendrive.

    Zune plus iPod: Most persons compare the actual Zune to be able to the Touch, however after seeing exactly how slender not to mention surprisingly small then light it happens to be, I think about it that would be a rather unique hybrid that combines qualities of both the entire Touch plus the Nano. It’s rather colourful and lovely OLED screen is actually slightly small than the actual touch screen, but the entire player itself feels quite a bit small not to mention lighter. It weighs regarding 2/3 because a lot, then typically is noticeably small throughout width and height, whilst being only a hair thicker.
