A 2U single-socket EPYC GPU server that takes 8 cards. Several members run it; the trade-off is noise.

== What people report ==
* 1a2b3c0967 runs 8 cards in a G292. It ships with dual 2200 W PSUs and risers for 8 cards. It sounds like a jet engine, but cools far better than the mining frame he tried first. {{Source|handle=1a2b3c0967|date=2026-10-04|link=https://discord.com/channels/1518634379604136178/1518692084729511967/1556146477019963423}} {{Source|handle=1a2b3c0967|date=2026-10-04|link=https://discord.com/channels/1518634379604136178/1518692084729511967/1556148492341346345}}
* cmdrwaka324 runs 5 CMP 170HX, 2 RTX 3090 and an Intel B60 in one: good BIOS and out-of-band management, an aggressive fan tune keeps idle noise like a big box fan, and the cards stay cool even in a garage in summer. {{Source|handle=cmdrwaka324|date=2026-10-25|link=https://discord.com/channels/1518634379604136178/1534370835220004885/1564042507090788514}} {{Source|handle=cmdrwaka324|date=2026-10-26|link=https://discord.com/channels/1518634379604136178/1534370835220004885/1564074018875904101}} {{Source|handle=cmdrwaka324|date=2026-10-26|link=https://discord.com/channels/1518634379604136178/1534370835220004885/1564116874063511654}}
* danske1 has one too: the stock fans are ear-piercing, and you need EPS-to-EPS cables because adapters do not fit in the back section. {{Source|handle=danske1|date=2026-10-26|link=https://discord.com/channels/1518634379604136178/1534370835220004885/1564151316819877921}}

== Topology ==
Each GPU pair sits on its own PCIe switch, so P2P is fast inside a pair and slower between pairs. Check the system block diagram before planning tensor-parallel groups. {{Source|handle=cmdrwaka324|date=2026-10-26|link=https://discord.com/channels/1518634379604136178/1534370835220004885/1564120367398780969}} The G292-Z20 and G292-Z24 are single socket; the 4U G482-Z52 is dual socket, so half the cards would cross the socket to reach the others. {{Source|handle=cmdrwaka324|date=2026-10-26|link=https://discord.com/channels/1518634379604136178/1534370835220004885/1564123814940508274}} {{Source|handle=cmdrwaka324|date=2026-10-26|link=https://discord.com/channels/1518634379604136178/1534370835220004885/1564125329067610224}}

== Noise ==
* A YouTube video ("Taming a 12,000 RPM Jet Engine! Gigabyte G292 2U AI Server Fan Tuning") has a Python script that lowers fan speed; the minimum is still about 3750 to 4000 rpm. {{Source|handle=a1rm4x|date=2026-10-15|link=https://discord.com/channels/1518634379604136178/1534370835220004885/1560284530244591637}} {{Source|handle=voidgiraffe|date=2026-10-15|link=https://discord.com/channels/1518634379604136178/1534370835220004885/1560290311111057529}} {{Source|handle=voidgiraffe|date=2026-10-15|link=https://discord.com/channels/1518634379604136178/1534370835220004885/1560334295153909822}}
* Con3po pins fan control to a thermal target (every card's memory or GPU at 75 C max) instead of a curve, which keeps the fans at the minimum they need. {{Source|handle=con3po7016|date=2026-10-15|link=https://discord.com/channels/1518634379604136178/1534370835220004885/1560332147875913871}}
* Not apartment friendly. More in [[Cooling and power]].

== Known issues ==
* EPS adapters do not fit at the back; use EPS-to-EPS cables. {{Source|handle=danske1|date=2026-10-26|link=https://discord.com/channels/1518634379604136178/1534370835220004885/1564151316819877921}} See [[Cooling and power]] for EPS pinout warnings.
