Is today patent day or something?
GDDR5 has CRC, but AFAIK that is generated on the fly and won't detect bit flips in the cells ... it's also not error correcting.
PS. I'm wrong, it is error correcting.
It's only computing CRCs on data bursts, so bit-flips in memory aren't detected. I don't see how this is similar to ECC in server memory. ECC memory actually stores the CRC so that when you later retrieve the value, you can see if there's been an error introduced.
Yes, I was attempting to use the same terminology as the original poster.This is incorrect. Server memory does not store CRCs as it won't allow you to correct. The store various ECCs which generally are variants of hamming code.
Really? mixing GDDR5 and ECC are that hard?
Theo disagrees.

I've yet to see an example of the opposite...On a related note, does anyone else get the impression Theo has no idea what he's talking about sometimes?

In general it isn't, but the one they used is.CRC is not error correcting.
I didn't know Aussie sources were koalas...Hmmmm so "half the planet" believes it has severe hw problems and it won't appear prior to Q2 10 and the other half believes it'll demo as early as September. NV has managed to close all possible leaks since the beginning of this summer, so I'd really love to know where either/or get their supposed infos from. Maybe I should start chewing eucalyptus leaves, hug a tree and claim to be an australian "source". I bet it'll work

If you take Charlie's fast-track story you'll end up with a mid-September availability of those chips. in the best of all possible cases they could have GT300 up and running at the time the HD5 series goes on sale. Retail availability still won't be there in 2009, but a demo in their own September event has to be achieved if they want to have the slightest change at debunking NV30=GT300.
On the other hand, there's still this group that has GT300 as a radical new design that's much smaller than GT200 and that has been secretly implanted in a lot of devices to take over the world, once again.
I find it interesting that people haven't started speculating why they decided to add the CRC to GDDR5.
An alternative to ECC for Tesla?Ok. Your thoughts? :smile:
Am I the only one that has that impression with many other online "journalists" (with very rare exceptions)?
It's just there so they can go closer to the edge as far as signal integrity is concerned.An alternative to ECC for Tesla?
