Ryzen "2" ?

DarkHorizon472 · 18 Apr 2018 at 17:07

Is the IMC much better on the 2nd generation of Ryzen ?

For me while not desperately slow it is a bit of a weakness for a cpu who’s performance is more strongly related to ram speed.

The second quote seems to be sourced from AMD which would suggest 1.35v is ok.

Still I would start again on the o/c stability testing and make sure cpu stress testing is reasonable. Or you could just drop the cpu 100mhz from where it is now and see if it suddenly becomes more stable from that.

The Robert Hallock video people have been referencing when Ryzen first launched, he goes on to say 1.4v is safe 24/7 for Ryzen.

Their more or less the same price. And ok cooler is one thing but in my instance a £7 mounting kit from Noctua alows me to use my existing one.

I see them as the same price.

Even the mobo are the same!

For example the Prime Pro from Asus, is basically the same price whether it be X370/470 or Z370.

So no I disagree, they are like for like the same price.

Heat yea, you have a point.

But then clock speed. The average oc on the 8700k is what like 4.7-4.8GHz?

And Ram speed goes up too 4000MHz.

Those numbers are dream world on Ryzen.

Clock speeds are irrelevant, you can have a thousand Ghz on the core and the memory and still have a slower CPU.

The multithreaded performance on Ryzen is clock for clock identical to Coffeelake, if that last video is true Ryzen is about to get a 10% IPC bump, which core for core clock for clock would put Ryzen 2### 10% ahead of Coffeelake.

There might not be much in it between the 8700K and 6 / 8 core Ryzen 2###.

Well I do hope the 2700x is a decent CPU as it will be a cheaper easier upgrade from my 1700.

It's about the same, 8700k only a tiny amount faster, by the time you factor heat and the 2700x being much cheaper (no expensive cooler needed), I'm going amd this time.

Plus the easy upgrade path

Even on the desktop I've found things to be a bit jittery with my 1700.

Something is wrong then. Me and my mates have done various Ryzen 5 builds,some with decentish RAM and others with bog standard stuff,and they have been fine.

Edit!!

Wasn't some of the earlier Ryzen CPUs affected by some fault which AMD would replace the CPU for free if it had it??

Its starting to sound like you have a problem there, that's not normal.

That was some compilation error I think.

I.e manifested it's self when compiling things like Linux kernels.

That was under heavy gcc compiling conditions on Linux.

My 1600 is smooth accross all applications, windows and linux. How do you mean 'jittery'?

Ah,OK. It does seem like something is not playing right with the setup opethdisciple has!

It's worth testing your 1700 for the segfault bug, if it has it it's a quick easy way to get a new 1700 that might have a much better IMC for zero outlay

Loque · 18 Apr 2018 at 18:56

how do you test for this segfault in windows? Is it a simple test program? Or do you have to have a degree in C+ to be able to decipher the scripts?

Hi all

I run at present a 1700X ( not overclocked) on a Asrock Taichi X370 with 32gig Corsair Vengeance LPX DDR4-3000 MHz.

I run 9/10 Virtual machines off it as well for other things i do would i notice a huge difference if i swapped over to the 2700x and also could i just swap the CPU out of my current build ?

And one last question what would my 1700X with box be worth at present ?

Thank you.

Start menu can be a little bit 'janky'.

Could be more ram related not being 100% stable.

There a 1700x for sale at the moment for £200. Which I thought was high.
