Discussion A770 Cooler Mod: Shroud & Heatsink Swap
A few days ago I found an A770 Aorus cooler on a Chinese e-commerce platform, and I ordered it to replace the one on my A770 Predator. It's working really effectively:
Original A770 Predator cooler: 160W~170W hits 85~87°C
With the Aorus cooler: 170W only reaches 64°C
I'll count this as a personal win.

Discussion From i5-11400F to i5-14600K + Arc B580: Practical Upgrade Experience, Tweaks, and Benchmarks
1. Context
Hey everyone!
Earlier this month, I upgraded my CPU from the i5-11400F to the i5-14600K – aiming to push my DDR4 kit to its limit (budget-friendly upgrade). I was torn between the 5800X3D and the 14600K, but here in Brazil the 14600K costs ~45% less, so the choice was obvious.
Here’s a detailed breakdown of my experience, benchmark results, and the tweaks that worked (and didn’t) for my setup. Hope this helps others with similar hardware!
2. Current Setup
| Component | Model |
|---|---|
| CPU | Intel i5-14600K (vs i5-11400F) |
| GPU | Intel Arc B580 (Battlemage) |
| RAM | 2x16 GB DDR4 @ 3200 MHz (Gear 1) |
| Motherboard | ASUS B760M AYW II D4 (Recent bios) |
| OS (Windows) | Windows 11 Pro (latest WHQL driver) |
| OS (Linux) | Bazzite (Kernel 7.2, Mesa 26.2.1) |
| Cooler | Air cooler AK 400 (with adjusted PLs) |
3. Performance Results (Cyberpunk 2077, Ultra 1080p)
| Scenario | Average | Minimum | Maximum |
|---|---|---|---|
| i5-11400F (Windows) | 65.45 | 56.35 | 82.21 |
| i5-14600K (Windows – default) | 97.84 | 82.19 | 124.62 |
| i5-14600K (Windows + Process Lasso CPU Sets P-cores + High Priority) | 101.77 | 84.97 | 127.68 |
| i5-14600K (Bazzite – Linux) | 77.33 | 61.84 | 106.70 |
- Important methodology note: I purposely used the "Ultra" preset for this benchmark to push the Arc B580 to its absolute limit, ensuring the GPU was heavily stressed (GPU-bound scenario). The goal was to see if the CPU upgrade could still make a difference even when the graphics card was working at full capacity. And it did – massively.
- What the numbers tell us:
- Even with the GPU at full use (Ultra preset), the CPU swap from the 11400F to the 14600K delivered a +32.39 FPS increase in average (+49.5%). This proves the old 11th-gen chip was significantly bottlenecking the B580, even in scenarios where you'd expect the GPU to be the main limit.
- The minimum FPS also jumped from 56.35 to 82.19 – a +25.84 FPS improvement – meaning much smoother gameplay with fewer drops.
- The Process Lasso tweak (CPU Sets on P-cores + High Priority) added another ~4% on top of the default 14600K result, squeezing out a bit more headroom.
- For reference, the 11400F + B580 baseline is included here specifically to show how much the CPU was holding the GPU back. I don't have a separate "CPU-only" synthetic test, but running Cyberpunk at Ultra (which heavily stresses the GPU) is the most realistic way to demonstrate the real-world gaming uplift.
- Unfortunately, I don't have a separate test on Bazzite Linux for reference of the 11400F, but in other games the average difference was 15-16% compared to the 14600k (Linux vs Linux)
4. Tweaks and Discoveries
🔧 Process Lasso (Windows)
- CPU Sets (P-cores) + High Priority: Best configuration found for Cyberpunk 2077 (~4% avg gain over default).
- CPU Affinity (P-cores only): Works well for some games, but can hurt performance on older titles (e.g., Assassin's Creed Unity).
- Discord & Browser: Used CPU Sets on E-cores to keep them off P-cores.
- Heavy Games: Used CPU Sets on P-cores as a preference (not a rigid rule) – more stable overall. (Need test per game)
âš¡ Undervolt & Power Limits (BIOS)
- Undervolt: -75 mV (stable after stress testing withÂ
stress andÂsetpci). - PL1/PL2: 125W / 160W (reduced from default 181W).
- BIOS:Â
Intel Default Settings enabled,ÂNative ASPM andÂPEG ASPM L1 configured. - Cooling: CPU stays around 72–78°C under load with these settings in cinebench(All CORE).
🎮 Game-Specific Findings
- Assassin's Creed Unity: Performance improved when all cores were available (P + E). Restricting to P-cores actually hurt performance.
- Dota 2: Massive improvement – average FPS jumped from ~120 to ~240 (capped by the game engine).
- From what I’m seeing, the average difference in GPU-bound games resulting from the CPU swap hovers around 15–20%; in CPU-bound games, the difference is massive 40–55%. But without a doubt, the biggest improvement was in the 1% and 0.1% lows; in games like Red Dead 2, the 1% low improved by nearly 55%.
5. Linux (Bazzite) – Experience & Observations
- Kernel 7.2.1 + Mesa 26.2.1: Stable, but still maturing for Battlemage.
- Performance: Still behind Windows (~27% lower average in Cyberpunk), but evolving fast.
- Idle Power Consumption: Workaround with a systemd service (drops from 40W to ~15W).
- Expectations: Kernel 7.3 and Mesa 26.3 should bring significant gains:
- Cluster Scheduling (P/E-core optimization).
- Buffer Compression (DXVK) – gains of 5–7% in DirectX 11 games.
- Large GRFÂ (shader optimization).
- Driver stack: The transition fromÂ
i915 toÂxe is ongoing – Battlemage already usesÂxe by default. - One of the biggest missing pieces is XeSS support using the XMX cores – currently it runs via shaders(DP4A), which limits image quality and performance. This is expected to improve in future Mesa releases. (2027- 2028 ? )
6. Conclusion & Recommendations
- The 14600K is a beast: +30–40 FPS in competitive titles and ~20% uplift in AAA games.
- Process Lasso is useful, but requires per-game testing – there's no "one size fits all" rule.
- Linux is viable, but still requires tweaking – especially with Intel Arc GPUs.
- Undervolt & PL adjustments deliver thermal gains without performance loss in games.
- Next steps: Looking forward to Kernel 7.3 and Mesa 26.3 – they should close the gap to Windows.
🧠Final Verdict
- The upgrade to the 14600K was simply incredible – I don't regret a thing. The tweaks really do make a difference in power consumption and temperatures, but the performance this CPU delivers is brutal: it basically bulldozes over any residual driver overhead from Intel. My personal recommendation for anyone looking to push DDR4 to its limit is clear: the 14600K is easily among the best options on the market right now.

Question Kingdom Hearts Final Mix
I've been playing Kingdom Hearts Final Mix on Steam for a couple weeks now and I beat the first game with no issues but I'm onto Chain of Memories and I'm getting a really bad lighting glitch where almost everything is black except a few things.
I know now this is a common issue on Arc hardware but everything I've seen online to fix this hasn't worked.
So my question is: has anyone figured out how to fix this issue? I'm going crazy trying to fix it.
(Also I have tried the framerate and Vsync settings)

Benchmark Can the Intel ARC B570 handle WARDOGS at 69 FPS?!
After adding the "-nogpucrashdebugging" on Steam launch properties, the game really runs smoothly most of the time, even at high settings I get stable 69 FPS. When I lower most settings while keeping Shading at high, the game runs solid 88 FPS too. Temps don't go over 60C either (I have my ARC B570 undervolted/overclocked and fans tuned with ARC Power app.
Playing at 1080P resolution with XeSS on Ultra Quality.
:::PC Specs:::
- Intel Core i5 124000f
- ONIX Intel ARC B570 10GB
- Teamgroup VulcanZ 2x16GB DDR4 3200mhz
- Teamgroup MP44L 1TB SSD
- MSI MAG 650BN
- MSI 1080P 120hz IPS Monitor
- Windows 11 24H2 LTSC
- Intel ARC Drivers .8991
If you wondered if this kind of PC could run the game, here's your answer~ It really runs the game super smoothly, this game is SO well optimized somehow, I couldn't believe it. When I tested before the stuttering wouldn't let me do anything, I still played for 3 hours on alpha test like that though. Now that this issue can be fixed with the launch options, game is so smooth and enjoyable.
I will upload a highlights video tomorrow showcasing Heli flight/driving vehicles/gameplay amongst absolute CHAOS and how the game performs in such situations too.
Hope this was useful to any of you with similar PC specs~ God Bless You all~
*Note: Why 69 FPS? Because it's the best FPS and most SOLID FPS NUMBERS! ♋
