Hi, I'm new to this forum, so go easy , eh ...

Specs are in my sig. VCore is 1.28125v with LLC enabled, Vtt is 1.2v, BCLK is 195 with Turbo on (195 x 21 = 4.095 Hz). HT is on (8 threads). Mem ratio is 6 giving 1170 MHz. Uncore multiplier is 16. Vdimm is 1.64v. IOH and ICH core are 1.2v. Everthing else is stock (I think). All power saving settings are on. F7 bios. Memory settings are 6-6-6-16 and Turbo.

I can run Prime 95 stable (v25.11, build 2) for 5+ hours. with a max temp of 79 deg C (recorded by Real Temp 3.0.) for the hottest core (the lowest is ~74 deg C). Idle is 40 / 41 deg C (for an ambient of 25 - 26 deg C).

So, all good so far.

However, when I run LinX (v0.6.1) after about 35 seconds I get an alarm from the MB speaker, as if a fan has failed, but max core temp is only about 74 deg C. However, even if I set all such alarms (including the CPU temp alarm) to off this still happens.

Any clues as to what is causing this? As it stands, this is preventing me from pushing higher

P.S. I have briefly run Prime 95 for ~10 minutes as a check (after which I stopped it) with a BCLK of 220 with Vtt at 1.24v and a low CPu multiplier of 12, so I am pretty sure that the board is good to go higher than 195.
