NEC Takes USB 3.0 to 16Gb/s

The boffins at NEC have worked out a system through which they have tripled the speed of USB 3.0 – from 4.8Gb/s data transfer to nearly 16Gb/s. What this means is that the SuperSpeed USB 3.0 now has the ability to go even faster – at least in NEC’s domain.

In most ways, NEC’s new technology works just like USB 3.0 and sends data as a stream of binary 1s and 0s. The difference lies in its ability to deliver and maintain high speed data transfer signals. The company has not actually developed a completely new bus; rather the scientists have come up with a way of delaying the rate at which data is fed back to the input signal.

If this sounds like mumbo-jumbo, it is first necessary to understand how SuperSpeed USB 3.0 works. When data throughput rates are very high, signals tend to become distorted. But the USB interface uses “adaptive equalization” to take care of this distortion. Under this technology, the signal is split into two and one part is fed back onto the input signal to give it stability.

However, when the frequency increases, the bus chip is expected to work a lot faster in order to complete the feedback and keep distortion in check. To work around this problem, NEC boffins seem to have found a method of adding a delay tied to the data rate to the feedback waveform.

“This procedure greatly reduces the nearest-neighbor inter-bit interference in the signal waveform and thus successfully alleviates the issue of feedback-time constraint inherent in conventional equalizers,” NEC’s scientists claimed. While the entire process might seem too complicated to be understood by normal computer users, it definitely seems to work.

So for all purposes, NEC now has a USB chip with the ability to transfer data at 16Gb/s. It now has to wait for the licensing bodies to license the new technology and open the doors for its use at a commercial level.

Code 43 in relation to pci related items, makes me think of the old polling problem u would get with soundcards - where at the point of reporting to the OS what the card was, it was either late in responding or responded b4 the question was asked, if u like.

The was an XP hotfix to download for such issues - however we're not in XP country are we.

I'm looking immediately at the Windows approved drivers that u installed. They're almost never the best drivers for any of the graphic cards they offer themselves for, only drivers that they've tested in-house themselves. Display a screen, some windows functions, nothing to do with non-microsoft games - but should be safe.

Obviously something went wrong there.

I'd goto the Programs section and remove these drivers, and either install ur old drivers or get another set straight from the card website.

I'm hesitant to say download the latest drivers, cos after Win7's release, the 9 series isn't a very beneficial card. U can try them tho. Or an early Win7 version.



Hey rasta thanks for your reply, when you say programs section do you mean going to C:\Nvidia and C:\Program Files\Nvidia
and just deleting these folders?

As i have tried this already and tried older drivers :(- do you think flashing my GFX bios will solve anything?

Small update- ive just installed my dads ATI X1950 pro hopefully i will completely wipe out anythign to do with Nvidia then put in my GX2 and install drivers



hmm... Shall i install with the latest driver or one just before latest?

thanks for any input at all

Formatting should of done the job. Reseat the card and remove other PCI cards and then install the drivers. I didn't think this sort of problem happened any more:o.

sadly i dont have any othe PCI cards instaled- and i hve tried reseating or using different PCIE slots :/

i dont know the signs of a failed gfx card but is this one of them? :s

Uninstall drivers, download and use driver cleaner, reinstall drivers direct from nvidia website and see what happens.

ok after instaling the ATI x1950 pro and completely wiping everythign to do with nvidia using driver sweeper then puttin the GX2 in and instaling the new driver from nvidia it still isnt working! :(

so i installed my GX2 into my dads computer using my PSU and voilà...... the same Code 43 on my dads computer meaning that its got to be somthing with the card! :(... was kind of hoping it would be my motherboard because it would be a little cheaper to fix

Im gnna see if theres a way to flash my card and see if that works any ideas?

hmm... well i ran the flashing software and it doesnt even pick up my graphic card lol! so no im totally out of options!



My GFX card is OEM (i think thats the term used when it came as a whole pc) but i notice EVGA have 10year warrenty on these cards so does that mean im liable to an RMA seing as the company warrenty is over

OEM is usually only a 1 year warranty not sure how evga would deal with a card u got in a machine but its worth a try and give them a bell and see what they say

If the card/OS is still misbehaving after a reformat... Either the card or the board is slowly dying or somewhere along your travels - *something* has changed in the BIOS' APIC / resource tables and windoze can't deal with the setup now.

Perhaps attempting to fudge it back by:

boot the machine with the ati
shutdown, and put the 9800 in another slot (still with the ati in and it still connected to the primary monitor)
remove all your network adapters
boot up and disable anything unnecessary in the bios...serial ports, firewire, everything.
save and exit and boot windoze - just let it use whatever it finds driver-wise (if it can't find any, don't specify a proper one - specify the standard VGA driver)

The dual-card approach *should* force your board and thus windoze to re-juggle your resources around and it *might* clear the errorcode...

It might not - but it's free to try and it can't hurt any...

EDIT: 'AGP apertures' aren't relevant to your chipset - it was to do with texture sizes and transfers across AGP about 10 years ago... For example: an old 3dmark used to throw a wobbler if it was set too low and it couldn't do the 64MB texture test...
...and if your bios lets you...manually set the resources for *every* slot... Youngie1337 is thinking the same thing I am I reckon...
...and if you get up and running...nvidia vista64 driver 182.50 is a good release to test with - it's the last one that avoids all this twaddle new WDDM1.1 business...
