AMD Ryzen 9 3900 Review: a Taste of Eco Mode
https://www.tomshardware.com/reviews/amd-ryzen-9-3900-review-eco-mode

Spoke to AMD about this part.
They are telling me it won't be available to the consumer as a stand alone part.

It is only for system integration so you can buy a PC from us with it inside, but you can't buy the CPU by itself from us, which is such a shame.

The 3900X supports and eco mode with the latest bios.

Just to make sure. You are not using the RGB fusion and APP center stuff from Giga, right?

Yes, I did install the Gigabyte app, but only after exhausting every other way I could think of to get the drivers installed (the one app claims to be able to check for newest drivers and install them....once it tried to actually install the drivers, the system crashed and rebooted like always though. I was trying everything I could think of including downloading bloatware lol).

Waiting for the 3950x release so i finally upgrade my 6800k (4,1ghz).

Since i wanna use the same RAM (64gb - 2133mhz) will the 3950x get crippled comparing with 3200mhz or 3600mhz RAM?

Gonna use it mainly for AGISOFT (Photogrammetry software) and for playing a few games.

Ryzen will perform worse with such slow DDR4.

 

[xtraLONG]

Any idea how worse? -10%? -20%?

Ryzen 3 should be ran ideally with 3200MHz minimum and 3600MHz is the sweet spot for optimal performance, 2133MHz in certain applications I can see hindering performance quite a bit.

You may find you can overclock your current RAM to 2400MHz, maybe 2666MHz if your lucky.

Lowest there is 2400, but you can extrapolate.
Seems to hit 5% performance, more depending on application. Games do suffer quite a bit, even when GPU bound

Ok, guess its time to OC this 2133mhz sticks and see what i get.

Any ideia how many 3950x are OCuk going to have in stock in 25 of November?

Seeing this graph (above - from your link) the hit wont be that severe (a few seconds between the 2400mhz and the 3600mhz), i was expecting way worse. I think i could handle a few months with the 2133mhz till i have time to upgrade to 3600mhz.

ps. i have a 1080ti


Thank you guys for the answers.

So far we are seeing zero stock, still pushing for more information but suspecting stock will be more limited than 3900X was and as such after launch the prices will explode, so be warned.

What classifies as a PC? Can I just buy a case from you and you ship it in the case?

As a last ditch effort, reflash the BIOS. if it still behaves same way after reflash - get an ASUS.

Alas, I have also already tried reflashing the bios....more than once....to the current as well as the previous bios version. The problem with getting a new mb is twofold...I have limited funds which I really depleted getting what I already have (I even got "better" parts than I usually would as I need this system to last a while). Secondly, as much as I am out of ideas as to what else it could be, I can't be completely certain replacing the motherboard would solve my problem (Gigabyte says the mb tests fine...hence why I am on here hoping for ideas to try that I may have missed as well as reassurance whether it could be the cpu as that is the only other thing I can think of...it just doesn't make sense to me that a cpu could cause this...)

4750mhz Ryzen 9 3950X vs 5.2ghz 9900ks vs 4.7+ghz 7980XE

 

[opethdisciple]

Does it actually do 4.7GHz tho? Or is it 4.7GHz on the box only and in practice it's more of a "my 3950x runs at 4.3-4.5Ghz job"

AMD be like "This is by design and what we meant was it does 4.7GHz given the best possible conditions"

One core occasionally in ideal conditions, like idling.

Don't care, in heavy workloads its quicker than Intel's OC 4.8Ghz 18 core, they must be bouncing their forehead off the keyboard because Cascade Lake is yet another refresh and DOA in the face of Zen 2.

Hope not had you chasing your tail but all my readings are using aida64 (memory bench) where I had 98.8 fsb and 1796 north bridge then they went 100/1800 after turning off spread spectrum. CPUz still will say 98.8 for clock! but any how turning it off is good for me, stopped erratic clocks in bios and everything else I mentioned.

Ok, so had a look around just now and in bios it is always above 100 in bios. The difference is the figure shoots up by around 0.2 in the bios when spread spectrum is off. Right now I am seeing something like 100.48 in bios with it off.

I was actually going crazy looking for spread spectrum in the bios at one point, but it seems if you manually have it fsb set to 100 then the option disappears. So you need to have it on auto to see it.

In HWiNFO64 my bus speed shows as 100. And in CPU-Z it is 99.98. I suppose it is better than before so I will leave it like this.

Have you changed anything else that maybe helping you see the exact 100 figure in the bios?

Does anyone here know if/what difference (if any) there is between using the top slot for a gpu vs the second as far as cpu vs mb and installing drivers?

My reason for asking is because I was able once to install the chipset driver: I was frustrated and so took my entire system apart and then reassembled it doing the only other changes I could think of - I put the gpu in the second slot and unplugged one of the 8-pin cpu power cables. For the first time I was able to install chipset drivers. I then switched the gpu to the top slot and was able, also for the first time, to install its drivers. I then assumed the left cpu power connector was bad (most say it is usually unnecessary anyway). I then used the system for a while and only had Windows issues which I assumed was from all the previous crashes/reboots corrupting the install. Confident that I had figured out the issue I then did a clean install of Windows...to once again not be able to install drivers. I since rather discounted this as a coincidence as I was able to install the gpu driver and even game with it back in the top slot, but could moving the gpu to a lower slot actually have made a difference for me being able to install the chipset driver? If so, would this point to a cpu issue? A motherboard issue? Just a coincidence? Something else?

2nd pcie slot is limited to 8x speed. The performance difference is very tiny

It may very well have had an effect on chipset driver install, especially with early drivers. I would dismiss it as a software bug until it happens again.

Thanks for your help. The thing is, that is the only time I have managed to install chipset/gpu drivers on my new system without a freeze/auto reboot regardless of drivers and bios (so not just restricted to early ones, this almost certainly is a hardware issue). It just never occurred to me to put the gpu back down a slot to see if I could get the chipset driver to install again as I always thought it just a coincidence that it did that once. If putting a gpu in a lower does make such a difference though with chipset driver installation (programs install fine, it is just any attempt to install a driver that is causing my new system to freeze/reboot) would that indicate a certain defective part (cpu or mb) or is there no way of knowing?

My technical knowledge is nonexistent and although my understanding is the lanes for the top pci slot come from the cpu with amd, I don't understand how/if the cpu would interfere with actual driver install (this is a 3700x on a x570 Gigabyte Master board and I have spent a ridiculous amount of time trying to figure out why trying to install any drivers results in a freeze/reboot.) Could this be a defective cpu? It just doesn't make sense that I only have an issue with drivers...
