Well. This is new.

daTS · Posted: Sun Dec 07, 2014 3:26 am Post subject: Well. This is new.

This is my seventh AMD build, and I've NEVER gotten this before. Since when did a processor need to install drivers?

I mean, it's no big deal, really, and definitely worth the 5.5GHz I can run when OC'd, but I've never seen this before.

Also, CoreTemp and several other CPU monitors are saying I'm running at a breezy ~40C (Liquid cooled) but my BIOS says I'm running close to 90C. I feel like that's incorrect, seeing as I've got my auto-shutdown protocol set at 75C. Any ideas why It'd say that?

Probably it's due to the CMT architecture - that the CPU have 8 integer ALUs but only 4 floating ALUs, so there is a driver to aid Windows on sharing threads between cores efficiently. (don't give floating- operations to core 1 if core 0 already has such while core 2 is free etc... this doesn't make a difference at other architectures IIRC).

I bought a AMD Athlon 64 X2 4200+ back in 2008. I remember having to manually install CPU drivers for it from a CD - it worked without drivers, but very slowly. My Phenom II didn't need a similar procedure (or maybe the drivers are just bundled with Windows).

Although if you swap hardware and keep the same Windows installation, I think it will always detect the new hardware and install drivers for them.

90'C is certainly incorrect, AMD desktop CPUs (at least Phenom IIs and FXs) tend to go unstable and give a BSOD at slightly above 70 AFAIK.

Hm, I was running my Athlon II (which is essentially a Phenom imo) around 80°C 'til last week - CPU fan met with an air compressor thereafter to clean off the dust - and I only ran into BIOS shutdowns, but no BSODs...

Every CPU has a driver to go along with it. It's just not always installed in the same manner.

The most likely situation is that your motherboard isn't able to read the temperature from your processor (maybe 9590's have this issue?) so the board defaults to reading 90c as thats where most CPU's shut down so there's really no point I suppose in reading higher. I would check the pins on the processor and maybe send it back if that's what's going on, as it may have a defective pin/missing one.

I've never seen this either with several AMD 8's.

EDIT: Scratch that, no need to send it back since CoreTemp is reading correctly, I would still reseat it though.
