“It’s all about the bad coordination, bad communication, bad support and
bad timing to launch this platform in my opinion. With all these issues, none
of us could start manufacture the boards sooner. Also, in January and
February, all board vendors’ production lines were occupied with Intel 200
series boards before Chinese New Year and tried to ship as much boards as we
can to ensure we won’t have stock issues while Asia was on New Year vacation.
In late December, AMD decided to pull in the launch date (it was scheduled to
launch in late Q2) and launched it right after Chinese New Year but AMD keep
the CPU supply quantity secret from us the whole time. They only shared the
data 2 weeks before the launch, we didn’t understand why they were doing it.
Also, their BIOS team and engineers were doing terrible jobs on supporting us
on the BIOS microcode updates, driver updates, CPU samples for testing. They
have done nothing they should have been doing to support the launch platform
partners and always delay or give no response on support requests. We were
all having huge issues to debug with limited AMD resource support including
validating the parts, and fixing the memory clock speed that is all limited
by AMD.
In general, it’s been too long for AMD to launch a new CPU, so they forgot
how to do it, so they launched the CPU just like they were launching the
graphics card. They didn’t care about the platform eco-system, so the
eco-system is suffering and stock is delayed.
We are flying in new batches every 3 days to try to fulfill the back orders
ASAP, so they should be all back in stock soon. With all the board reviews
released, per Newegg and Amazon, the AMD memory limitation issue is slowing
down the sales though.
We need your help to feedback that to AMD as well on their supports issues.”
