AMD Shanghai/Deneb Review Thread

HT3.1 is not supported yet. these 45nm cpus were the first to actually support HT 3.0 as the original phenoms only half supported it. HT 3.1 has already been designed but hasn't been implemented yet.

now it all makes sense am2+ 2600mhz am3 board supported 2,600-3,200mhz. maybe.

now it all makes sense am2+ 2600mhz am3 board supported 2,600-3,200mhz. maybe.

the am2+ chips and the am3 chip should have the same exact ht speeds. ht 3.0 has a max hyper transport speed of 2.6ghz. i have always thought that the only difference between the two chips was one supported ddr3 and ddr2 and one supported ddr2. http://www.hypertransport.org/defaul...Specifications

so just because everyone was curious about am2+ cpus using ddr3 i asked about it. k10 does infact have a ddr3 controller on it but am2+ cpus can not use it because it is disabled through fuses. so i asked if am2+ cpus could work in am3 motherboards. he wasn't sure but he said if it would work it would not work with ddr3. so even if am2+ cpus would work in am3 motherboards the am3 boards would have to have ddr2 memory slots.
edit: so im doing a google search for fuses on k10 and i get this from our own forums from last year when k10 was first released: http://www.xtremesystems.org/forums/...&postcount=699. it also states that there is a ddr3 controller but it is disabled through fuses.

IF the AM2+ Deneb works in AM3 motherboards, as someone has claimed, then it would be because of the following:

(DISCLAIMER: This is based ONLY on my opinion and a guess)

There might not really be a "true" AM2+ Deneb. All DENEB chips might be AM3 chips that will work on AM3 or AM2+ motherboards. They may just release the first couple of chips before AM3 motherboards are available and say that they are AM2+ Denebs for marketing purposes.
