I think my favorite one is just
PCIe Stop & Scream Support [Disable]when you open the IntelRCSetup (what's RC?) the setup utility tells you "if you change some of these settings the system may malfunction"
that's an understatement of the year
-
heyyyyyy. check this out
i bought one of those chinese motherboards which get the UEFI package from American Megatrends and then enable options with the guiding principle of "YES."
check out how many juicy bits it has
you can turn the memory scrambler on and off! it even tells you the seed it has on, i think, this specific boot?
@whitequark love to swizzle my bits for maintenance
-
@whitequark lol nice... not sure if you saw my lab upgrade threads recently but i just scored half a TB of free DDR4 RDIMM and a pair of xeon platinums that i'm starting to deploy (it's a lot of work because each upgrade is displacing RAM/CPU that I then want to use to upgrade something else, so it's not just a single part swap)
@azonenberg niiiiice
I bought 16GB of 2133 DDR4 for this thing (it's going to be a quiet build server) plus 100GB or something of Intel Optane that I'll use as swap; this is my strategy for getting 100GB of almost-RAM for $100 or so

you can disable GPIO lockdown!
there's a function that prevents malicious UEFI Flash wearout, a type of attack I have not considered before. also you can turn it off
you can set UEFI boot stage breakpoints!
@whitequark UEFI boot stage break points is crazy. I want this now.

@whitequark @azonenberg I see there is a whole load of cheap Optane floating around on eBay.

it also lets you unlock these specific MSRs that are completely undocumented and have no search hits besides some hackintosh person poking at them. no idea what they do or why there's a toggle

if you want this motherboard, it is unbelievably easy. it's on sale for 30€, including the Xeon CPU it needs: https://www.aliexpress.com/item/1005008826220177.html
note that it is made to a price point and it is barebones: it has no USB3, for example. but on the flipside, you can split its PCIe x16 graphics port four ways and connect six PCIe Gen3 NVMe drives to it (plus some SATA)

@jyn do you have 30 euro? it could be yours https://social.treehouse.systems/@whitequark/116143280563821829

@kbm0 @azonenberg been for a while yeah! 3DXpoint is great

@whitequark I should start a conspiracy theory that spread spectrum clocking and memory scrambling are evil attempts to decrease your performance by intel, and use this board to "prove" it

@kbm0 @whitequark @azonenberg is it really still cheap? I've been a refurb enterprise flash enjoyer but all the usual places got the same price rise as the new market

@whitequark Isn't the RAM worth more than the price of the bundle these days?

@david_chisnall @whitequark the (sold out) ram version adds 65€

@david_chisnall a 2x8GB bundle cost me like 3 times the motherboard lol

@implr @whitequark @azonenberg Maybe not for much longer, given the way storage prices are going... I get the impression that there is a lot of it left over from back when Intel were pushing it for the desktop market.

@whitequark @azonenberg ... you can still buy optane ??!?

@niconiconi beautiful

PCIe Stop & Scream Support [Disable]@whitequark i like the fact that when i google that, the search results contain a bunch of references, some manual entries, but apparently no explanations anywhere.
oxide was right to remove the bios root and branch
