FiringSquad brengt ons meer info over de AMD 760 chipset delay die onlangs door Gigabyte aangekondigd werd. Kort erna kreeg Dr. Tom al de geruststelling van AMD zelf dat alles nog gewoon volgens schema loopt. Anyway, volgens de info van FiringSquad was er inderdaad sprake van een klein probleempie met de AMD 760 die echter direct gefixed kon worden door het aanbrengen van een extern circuit:
After discussing the matter with a trusted source, we've discovered that a glitch has indeed been found with the current version of the chip (B2), but a fix has already been implemented by AMD.
According to our source, under certain conditions the 761 Northbridge will generate a clock glitch into the CPU that may cause the system to hang. To resolve this, motherboard manufacturers will have to integrate an external circuit to filter out the glitch.
We're assuming that it is this glitch that the Gigabyte representative is referring to. If this is indeed the case, the representative may not have known that a fix exists for this and in fact has already been corrected on AMD's latest reference design, Corona EVT-8 (Which includes the circuit.) For reference, Corona EVT-8 was made after initial samples of Gigabyte's 7DX were released. [break]Er blijft echter nog steeds wat onduidelijkheid bestaan over de tijdige implementatie van de fix door mobo fabrikanten. Hoewel dit dus misschien betekent dat de eerste plankjes wat later op de markt komen moeten we niet vergeten dat 133MHz Athlons en de AMD 760 chipset pas begin volgend jaar echt goed leverbaar worden:[/break]So now that the problem is known and the fix determined, AMD and its motherboard partners must decide how they will proceed. For the first batch of motherboards, the fix will have to be resolved via the previously mentioned external circuit.
It remains to be seen if AMD will resolve this glitch with an upcoming revision of 761. This next revision is rumored to solve the heat-related issues some have encountered.
Our source suggested that some motherboard manufacturers don't even know the full story behind the glitch with B2, which hints that a few manufacturers may not be prepared to implement a fix.
[...] Now that the public knows the glitch exists, it's up to motherboard manufacturers to implement the fix as quickly as possible. Will this lead to some delays for manufacturers? We can't answer that question, but during our conversations with AMD, they made it clear that 760 and 266MHz Athlons won't be as readily accessible in the retail channel upon launch as their products have been in the past -- "widespread availability" isn't expected until the first quarter of next year.
