I see a ton of terrible Corsair support stories on here. I wanted to share a different experience I had just to balance it out.

Had a Corsair Vengeance RGB 64GB (2x32GB DDR4) that was gifted to me years ago. One stick gave my pc reboots since day #1 so I was using it on and off. Always thought it was some compatibility issues with my mobo. Got to know about MemTest and tested it out a few weeks ago - it would abort at 58% from sheer error count lol. Kit was probably 3-4 years old easy. The person who gifted me this was no longer a part of my life and there was no way to reach out to them for receipts.

Submitted a ticket in late April with no expectations.

Timeline:

• Apr 22: Submitted ticket, explained everything honestly.
• Apr 23: Was asked for some pictures and some other information. RMA approved within 24 hours.
• Apr 25: Agent Wayne L (GOAT) confirmed everything, and kept me in the loop
• Shipped the bad kit back somewhere around Apr 28
• May 4: Replacement shipped
• May 7: Delivered at my door (3 days from Taiwan to WA, US lol)

Genuinely hope y'all also have good experiences like this 😸 (not sponsored)

In another post I had someone ask me about the power draw of the 4x 3090 setup so I'm sharing a a full test I conducted to understand the efficiency curve. Used this blog post (not mine) as a reference.

Setup:

• GPUs: 4x RTX 3090 (Dell OEM, EVGA XC3, 2x ASUS Strix)
• PCIe Topology: Gen 3 (Bifurcated: x16 / x8 / x8 / x4)
• Model: Qwen3.6-27B (FP16)
• Backend: vLLM v0.20.2 (TP=4)

Power Limit (W)	Output (t/s)	Prompt Processing (t/s)	Total Throughput (t/s)	Efficiency (t/joule)
350/390 (Unrestricted)	29	239	269	0.77
300	29	238	268	0.89
275	29	236	265	0.96
250	29	232	261	1.04
220	27	220	248	1.13
200	24	196	221	1.11

Takeaways:

1. The 220W Sweet Spot: Peak efficiency (matches the blog's findings)
2. Diminishing Returns: Increasing the limit beyond 250W provides diminishing returns

Hope this helps someone. Happy to answer any questions.

I'm VERY satisfied with Qwen 3.6 27B as a daily driver, but I would still like to know if there are any better/bigger models I can run on this setup. My understanding is that the best I can do is DSv4 at Q2 - not sure if it's fully supported yet though.

Additional context: it's an open build on a generic mining frame. I'm cooling it with 10x TL-C12C-S (5 on each side of gpus perpendicularly). I finished building this very recently so I'm open to suggestions on how to improve it.
