I pre ord' a Ryzen 7 1800X last night.

Feel free to have it shipped to my address ;)

Some notes on DDR4 memory for new Ryzen boards.

"Hi there


Just to help educate a little.

Ryzen is compatible with all current DDR4 memory and officially supports upto 3600MHz.

However the sweet spot is 2400-2666MHz, this speed will work with all mainboards including cheaper options.

3000MHz and above will ONLY work at such frequencies in the flagship mainboards like Asus Crosshair for example and even then the maximum stable speed we achieve with a lot of messing around was 3200MHz, which really makes 3000MHz the maximum speed we advise.

Of course you could buy 3200 or even 3600 kit now, and just run it at a lower frequency with more aggressive CAS Timings and as BIOS updates come out then you might be able to achieve higher frequency.

As such we recommend 2400-3000MHz kits for use with Ryzen, faster kits will work just fine but you might have to run them below the rated speed and just set the memory timings more aggressive. :)"

Thanks for the notes.

I went with 16GB 2666MHz CL15 kit.

It's less that CPUs are more expensive than they used to be and more that there are price categories that simply didn't exist back then. Top-end chips these days are a bit of a niche market that may-or-may-not be profitable, but drastically affect potential customers' perception in that customers often compare brands by looking at the top-end products even if they are not affordable to determine which brand is "better", then selecting a product from that brand that's within their price-range even if there's a better option at the same price or less from another brand.

Its AMD, you can go with DDR4 unbuffered ECC on desktop. But board has to be Asus, because other brands suck*.

*Edit: to clear up, the other brands usually just disable ECC support in BIOS/UEFI, although hardware supports it, and usually only ASUS does a proper job and enables it.

Wtf is a "AMD fTPM", which can be seen in Manual of AB350M ?..

Btw, speaking of Asrock, geizhals.eu lists it as "ECC supported", however they hardly are. There is a single question on Asrock forums regarding ECC capability of these boards, and the official Asrock answer was: "Whats your CPU"...

I mean... I have 8gig ECC AMD server, which is powered by .... $20 CPU. Mainboard is ofc Asus.

Something to do with this perhaps?

I found that its a TPM implementation done completely in firmware.
That could be the reason for AMD to abadon libreboot...

Basically, they are indeed shoving drm and trojan stuff via blob firmware even on desktop. Nobody really need this, if someone wants true security for own data, its should be detachable module - but this is an integrated blackbox.

Could be that modern Linux desktop OS would be as exploitable as Android, within the firmware RTOS.

The spec for the ASUS board I went for doesn't claim to support ECC, unfortunately. This was the most expensive of the ASUS boards, and the ASUS boards were the *only* AM4/Ryzen compatible boards I could find in my store at this time..

From what I read on OCUK forums or somewhere, Intel already has something like this.
I guess we're never really going to be allowed to be left to our own devices, pun not quite intended.

Well, Intel was always evil. For example, I can't deactivate IPMI, even if I don't use it.
With AMD it was different, unexpected.

Does it work on Linux at all or is this whole DRM-madness making it incompatible?

Looks somewhat promising.

I'd forgotten about no windows7 drivers for Intel or AMD, or at least official ones.

AMD's latest CPUs/APUs contain a small programmable core which manages all the power management stuff without OS-intervention apparently, so with any luck (meh!) someone'll create something.

From one of the biggest Hardware publications in Turkey apparently.

To sum up the things he stated;

"Overclock is no problem at all. Though we can not say a certain frequency due to NDA, I can say that it is impressive. Overclockers will be happy."
"I have friends from AMD Engineering department due to my experience in the hardware industry. Zen 2 or Zen B will be even more competitive. So we can say that Intel shall brood on the future"
"With our overclocked 1800x sample,under Noctua cooler given by AMD, we have passed beyond the stock single thread performance of 7700k, in a specific bench, and the temps were great. We had no concern about temps during our run which passes the ST performance of 7700k."
"In some benchmarks AMD(!). It seems ironical yes but AMD is presenting a CPU performance that Intel can not keep up with even with their 10 core 6950x!"
"Breaking NDA won't be a problem since the scores are beyond fantastic. But we will stick with the tradition."
"With one click I can reach great OC's. So I won't really bother with the manual OC no more."
"Single thread score will be so great. According to this performance we can say that 7700K will be history, even for gaming, from now on" he said.
"Intel shall shake themself. Because Ryzen will be a great choice for Overclock enthusiast."
