i5 6400/gtx 1070/16gb DDR3L 1600mhz

Hey huys

Someone already try the game with this configuration ?
I know CPU is below official specs (and perhaps RAM) but I also know that the game is well optimized so ...

Perhaps someone has an idea or an experiment ?

Thanks

Your RAM will make the game entirely unplayable sorry. The game needs very fast RAM. Same goes for the CPU.

The game is well optimised in the way that it's great at utilizing all of your hardware, far more than most games. But, if you don't have enough system resources for it to use it will run terribly (and you don't).

So yeah you would need a new build to play the game, though you can still hang on to that 1070 :)

Not true you can run at low. With some tune to you Nvidia profile tuned for vr you should be running well on low. The 1070 will bring your system to Low and that's not a bad thing. I've already tested your system config and I report low but playable. This is of course if your computer is already optimized. If you are running great on say Doom 2016 with 120FPS which im sure you can do as I tested that already to. Your at 137fps~ so that means low on HLA. Thats great tho maybe you can put one tab to med but remember its good to be smooth and stable. Low and have a great experience. Thanks for interest in Half Life Alyx be sure to contact me for more support.

Lucas, no way, people barely get a playable experience on 2133mhz RAM, how could 1600mhz DDR3 even hope to be playable? Settings wont matter, being on low will do nothing.

Would it run? Yeah, sure - but it would be a terrible, stuttery, mess.

Thank you guys for the answers and, to be honest I was more scared about CPU and Ram than about GPU.

@LUCAS so you've tryed with i5 6400 and DDR3L @1600mhz ?

No problem with low, since it seems to be gorgeous anyway!

I doubt it, I think he's underestimating the importance of RAM bandwidth in Alyx. Many people who were posting here with problems with performance found out that they were running their RAM speed at 2133 or lower. Those running at 1600mhz and lower found the game unplayable.

I myself disabled Dual Channel on my 3200mhz RAM, running at 1600mhz, to see what it was like and I agree it is unplayable.

Adjusting settings doesn't reduce the games need for memory bandwidth either, so you can't scrape by on low settings.

You don't have to take my word for it either, you can find a ton of posts on here saying the same thing.

I already saw some gameplay videos with i5 6400 and it SEEMS to work pretty much correctly, even if in flat it's not really possible to see what you see into the headset.

So even if CPU is under, I guess it can run on it.

BUT I read here and there that DDR3 could be a problem, because of frequency, and wanted to be sure of that by comparing if someone already tried that out over here.

To be honest, I'm planning to buy a headset (mainly for that game) so I can't even give a shot to the game and refound if it doesn't work ...

Yeah, that's the point i was worrying about ...

Well, download and unzip the program 'MaxxMEM2'. Run it and wait for a bit, it might appear unresponsive for 10-20 secs. Click the "Start Bench" button and wait for that to complete. You will get a GByte/s number at the end, and that's your overall memory bandwidth. I'm not sure the min memory bandwidth you will want for acceptable performance, but it's not under 20 GByte/s. I imagine your bandwidth is somewhere around the 12-13 GByte/s mark.

[Chi]

Here are the results :
READ 17363MByte/s
WRITE 23056MBytes/s
COPY 20603MBytes/s
LATENCY 77.8ns

Which numbers are important here ?
What do you think ?

[Chi]

And there is also a BIG 20.34 Gbyte/s that appears on top of that

[TimmyP]

Dont listen to Bilbo. Everything he says, and has said since before the game was released is a total waste.

Hey noob! Lower gens of DDR have tighter timings which make up for a lot of the bandwidth that would have been lost, should it just be the same exact thing with faster speeds somehow. (Like you think).

This will be playable on DDR3 1600mhz (uh there a ****load of i5s\DDR3 playing the game herr durr) itll be playable at 2133mhz as long as the CPU... wait it even works on FX-6300\8350 too so you dont even need a relevant CPU (though the older Intel i cores wont work)

Have a good day! Sorry you wasted your time downloading pointless software that nobody really uses. Id probably watch your malware cleaner!

[Super Bambaspis]

Thanks Timmy :)

Kinda haven't slept in 53 hours.

I can't say about the CPU and the RAM, however, the 1070 runs this game very smooth. A GREAT game!

I have to say sorry about suggesting maxxmem2, it doesn't appear to be giving reliable benches anymore for some reason. I used to use it to some success... Or maybe it always was bad! Not dangerous though, as my friend Timmy suggests. Best tool for checking your memory bandwidth, if you want to, remains AIDA64 (though you have to pay to see your results). Maybe there's other good software out there for it, but I'm not aware of it.
