LG’s 27-inch Tandem OLED gaming monitor is cheaper than ever

The price of LG’s UltraGear 27GX700A-B 1440p gaming monitor that came out last August has dropped to nearly its best price yet. You can grab it at Amazon for $484.99 or at LG for $499.99 (originally $599.99). That’s a great deal considering this is one of LG’s Primary RGB Tandem panels built with fourth-generation WOLED […]

Dbrand’s Steam Machine Companion Cube is canceled

Dbrand announced Monday that it's refunding everyone who bought its Steam Machine Companion Cube, which it said it made "without a license from Valve." Dbrand announced the Portal-themed Steam Machine accessory in November and took preorders for it last Monday. But a few days later, the product had disappeared from the company's website and the […]

It’s a bad time to want a new computer

It's not exactly surprising that RAMaggeddon is making new tech hardware really expensive. But if you've been in the market for things like a new computer or tablet, this week has been filled with sticker shock. Given how many companies announced price hikes related to component shortages, it seems unlikely things will get cheaper any […]

Riot now lets you enable its anti-cheat when you want to

If League of Legends and Valorant players have the right hardware and elect to opt into "pre-boot security mechanisms and Windows' own native protection features," then, starting today, they can switch the Vanguard anti-cheat software from always-on to one that's "on demand." With "Vanguard Pre-Check," the kernel-level driver won't launch when your system does, according […]

How much would the Steam Machine cost to build?

The Steam Machine is here, with a base price of $1,049. Yes, that's nearly twice the price of a PS5, but what you're buying here isn't a console but a full-on PC - and a tiny one at that. Valve says it's selling the Steam Machine basically at cost. So we asked ourselves: What would […]

I’m not giving up my Steam Deck for MSI’s new Claw

This is not a review of the MSI Claw 8 EX AI Plus, the first gaming handheld available with Intel's new Arc G3 Extreme handheld gaming chip. Now that my colleague Sean Hollister is done reviewing the Steam Machine, I'll let him go deep on the new Claw at some point in the future. This […]

Valve describes just how brutal RAM negotiations are in 2026

Valve's Steam Machine finally has a price: a whopping $1,049 for the 512GB configuration or $1,349 for the 2TB version. And those are without bundled controllers, which drive up the cost more. The prices are so high in part because Valve isn't subsidizing the hardware, and the company has already indicated that the component crisis […]

Here’s how you can reserve a Steam Machine

The Steam Machine is here, but getting one is a little complicated. Valve is taking preorders using a reservation system, which is intended to make the process more fair and harder for bots to exploit. However, it's a bit different than the $5 reservations Valve used for the Steam Deck. Starting today, you can sign […]

Valve explains why it isn’t subsidizing the Steam Machine

Valve finally announced the price of the Steam Machine, and like a lot of new gadgets these days, it's not cheap: It starts at $1,049 for a 512GB model, and a 2TB model costs $300 more. Configurations with a bundled Steam Controller cost an extra $79 each. Despite Valve offering a console alternative with the […]

NVIDIA peermem invalid argument-fix

nvidia-peermem "Invalid argument" on Ubuntu — Fix GPUDirect RDMA with DMA-BUF TL;DR: If modprobe nvidia-peermem fails with Invalid argument ( -EINVAL ) on a system using the inbox Ubuntu InfiniBand stack ( rdma-core ), the module is not broken and you do not need it. nvidia-peermem requires an API that only exists in MLNX_OFED. On Hopper/Blackwell GPUs with the NVIDIA open driver, use DMA-BUF instead — it does GPUDirect RDMA natively. The one gotcha: you must enable nvidia-drm modeset=1 . Applies to: Ubuntu 22.04 / 24.04, inbox rdma-core stack, NVIDIA open kernel driver, H100 / H200 / B200, ConnectX-6/7 (or any HCA with ODP support). The symptom $ sudo modprobe nvidia-peermem modprobe: ERROR: could not insert 'nvidia_peermem' : Invalid argument dmesg shows nvidia-peermem loaded but registered nothing, or the load returns -EINVAL . GPUDirect RDMA appears to be unavailable. Why this happens (and why it is not a bug) nvidia-peermem is the legacy path for GPUDirect RDMA. It registers GPU memory with the InfiniBand subsystem through a Mellanox-proprietary kernel API: ib_register_peer_memory_client () That symbol only exists in MLNX_OFED's build of ib_core . It is not in the mainline kernel, and it is not in rdma-core , which is the inbox InfiniBand stack on Ubuntu. If you are on the inbox stack, nvidia-peermem was compiled without that API present, so it can never bind and always returns Invalid argument . No module parameter or config change will fix it, because the thing it needs was never there. Do not install MLNX_OFED just to make nvidia-peermem load. That works, but it is the wrong fix — you would be adding a heavy proprietary stack to revive an obsolete module. There is a native path already in your kernel. The fix: use DMA-BUF On Hopper and newer with the open driver, GPUDirect RDMA works through DMA-BUF , a mainline Linux framework. No external module, no MLNX_OFED. Requirements (check these first) NVIDIA open kernel driver (not the proprietary build) nvidia-drm
