@Plexus sure, for just work purposes I have W530 here and it works very well after upgraded it to i7 quad core and pulled 24GB RAM in to the machine.
A friend of mine thinking about getting a secure machine (coreboot, heads and so on), so I thought about an allrounder, that could have more power (just to have it, without concrete purposes). Is there any possibility to use a better grafic card, for example?
Awesome to hear! Im glad things are working for you.
Ah thats great to hear, I have also been involved with heads for quite some time and the approach is second to none.
Well again that comes down to use case. I mean, it really depends on what the intention is. As I’m sure you know a w530 with i7 and 24Gb and SSD is going to do very well for all of the envisaged use cases I mentioned earlier.
The GPU has always been an interesting conversation with QubesOS. GPU passthrough is an age old topic going back to the start of the project. IOMMU/VT-d/AMD-Vi certainly help, but that is by no means the solution. I don’t see anyone taking up QubesOS wit a view to playing games, so I assume its the number crunching ability that is the topic of conversation in that regard?
The problem is, that I’m not sure, if this friend of mine can manage Qubes for a long time in practice, so in case of he will not manage it for his purposes, I will install something like PureOS or even make a dual boot with windows (dual boot with Qubes does not make sense), if he does need windows for some reasons in future. Thats why I thought about a machine that can even manage video edditing with GTX card or something like that.
Nitropad offers T430 with i7 3840QM (but just with 16GB of RAM, why not 32??). For just Qubes it’s enough.
That’s the point, I don’t think, that Qubes will get though to a better GPU. But the problem is, that there are not just people, who want to play games with G/RTX or something like that. There are some, who want to edit videos and photos for there work. On that point Qubes would be a very nice extra on security… but I think, these are wishes that will not come true

The X230/T430/T530 have 2 RAM slots. Only the W530 has 4 RAM slots (32GB = 4 slots x 8GB/slot)
For the W530, the fastest 55W TDP CPU is probably the i7-3940XM, the fastest 45W TDP CPU is i7-3840QM.
or, sure… forgot that.
ah, ok, so i can do another upgrade… but i think, than i need a better cooler
Just doing some surfing around about the w4530. I’m find them on ebay with i7-3820, not the i7-3740QM as suggested above. Is the 3820 an improvement over the 3740?
Have I it right that the w530 has four RAM slots that would take say 4 X 8gb?
I’m giving consideration to maybe getting one if it can get 32gb working.
Yes, i7-3820qm is quad-core and so will have four slots according to the specs:
Thank you very much for that spec sheet
At the moment I am using another laptop for gpu intensive things. I’d rather use a dedicated gaming laptop (not connected to the net) than gaming in Qubes. The same applies for some video/photo related stuff. The basic/normal stuff is also working with Qubes quite well (like editing photos and videos).
As for all the other stuff I use Qubes on an older corebooted Lenovo laptop with 16GB RAM and I am very satisfied. I usually run a dozen Qubes without any problems.
The only problems I have run into in the past related to insufficient memory had to do with a Windows7 Qube. I had allocated half the memory to this Qube in order to try a few things. Other than that I have never had trouble with memory.
Of course, if you’d like to render something in blender or work with certain CAD programmes then you’re more likely to run into trouble at some point. Or it will just take more time, it all depends.
I guess it depends not only on your use case but also expectations/wishes. I’m currently on a dual core i5 2520M with 16GB RAM and SATA SSD and don’t use heavy programs a lot. I can run a lot of qubes at the same time(including memory heavy Windows qubes) without using manual memory management. In that respect it is perfectly fine. However, I would still like a faster CPU with more cores and preferably also a NVME SSD. It takes a few minutes to boot the machine, starting a VM takes some time. A single one is doable, but multiple at the same time or after each other takes too long for my taste. For example, when I want to open Thunderbird, it boots up my VM, then the vault VM with GPG keys and when Thunderbird is finally open and usable, almost a minute has passed. Every time I shut a VM down, the HDD led blinks constantly and my system becomes largely unresponsive, sometimes even more than 10 seconds. Booting a Windows VM can take multiple minutes. Don’t get me wrong, for such an old machine I’m impressed that it can run so many VMs concurrently, also thanks to the optimizations done by Qubes devs. If I were just to run VMware/VirtualBox on a standard Linux or Windows system, it would be impossible. I consider this hardware usable for Qubes OS, but there is a difference between usable and capable of providing a smooth experience. I can get annoyed often at having to wait all the time. Also keep in mind that 2nd and 3d gen Intel i CPU’s are now also EOL and not receiving microcode updates anymore.
Heavily recommended use premium thinkpad workstations if you want something better then ssh in console.
P-series based on Xeon.
I use i7 and 32G ddr4 ram , evo SSD , while no GPU acceleration and not fast CPU, no OpenGL support, it works but not perfect. For example, sluggish web browsing if simple.
Also every each VM need thousand tweaks
grub/sheduler/ram <400mb, modify kernels.
4.1 works more slower than 4.0
what I don’t really understand (even after reading some tutorials) is the allocation of the RAM to the VMs. What does make sense? How much “initial mem” and “max mem” should I give to the VMs? Sure, it depends on what kind of VM it is. Sometimes its a little bit hard to understand, what the VM really needs.
For example untrusted VM for youtube, surfing and such things or VM for just thunderbird and so on.
After the great advice here I have decided to grab a w530. I’ll replace the hd with a fast ssd and max out the RAM. And of course get rid of win10 and put qubes on it!
Would someone who has done this be kind enough to recommend some top shelf, quality RAM that would be suitable for this laptop?
Could you elaborate on that second part? What do you mean the laptop isn’t good for all-day use? I’m thinking about getting a Librem 14 but I want to do more research into the quality of their products before spending over $2k on it.
Usually you don’t have to do anything, see the following post:
There are ways to reduce memory consumption like Mirage firewall and some fine tuning but in my experience 16GB is enough for ordinary stuff.
I think he is just talking about writing on a foreign keyboard layout/mapping isn’t a good solution for everyday use.
I just mean that the librem without german keyboard layout is not good for my purposes.
@Raphael_Balthazar: ah, ok. But what about, if i’m running a VM that needs rather much RAM and there I have something like 1G intial and 4G max and need more? Will it automaticaly give me more than max?
As far as I know you have to increase the maximum memory in the settings of said Qube. Then it should be able to use more than 4GB but also only if needed.
ah, ok, thanks!
I have nothing special, just 3 of 8GB DDR3 PC3-12800 1600MHz SoDIMM
Thanks for that. I’m thinking of Corsair or Kingston as they get good wraps. Not that I’d know that difference probably
