Topic: Why are the VRMs on some of the 280x's running in the 100C range?!?! - page 2. (Read 1624 times)

I got 1 280x in a windows box, ran it at 730KH/s and yes VRAM temp is 103C for #1 and 101C for #2. I don't know is this a problem though?

If they were to die, I guess I would just return them. I mean they do have warranty?

EDIT: I also noticed something funny, when running the GPU-Z tools the hashrate actually drops about 40KH/s for me. Simply closing it put's it back at 730KH/s.

Ok, I'm looking for a way to get VRM temps in Debian... seems hard to find an app that will do it

I have two Sapphire Dual X 280X VRM at 106 and 96 C been running for almost a month. I hope it doesn't fry.

I hear ya man

Hmm.. I got 2 Sapphire 280x Vapor-X each pushing about 760KH/s, both hoover around 60-70C, never been higher. I love these cards.. All my 7950's struggle to keep under 80C..

This is for the VRM temps not core temps.  VRM temps can be read in GPUZ

You are right.  I have a toxic that performs great too.  This is for the cards that have throttling issues

My Sapphire Toxic is performing great at full load. Its been going full boat for the past 24 hours and doesnt go above 72 C.

For all of you that have throttling 280x's from running scrypt that bounce from 64-99% it is because the VRMs are running over 100C!

Last year's 7970s did not have this problem!

So after buying some heatsinks yesterday and getting ready to put them on, guess what I found when I opened a card up?  Heat sinks already on the card...

So what is going on?!?!?!  MSI released a fix for their cards.  SAPPHIRE GET YOUR ASS IN THE GAME AND FIX THIS NOW.

Just to be clear I have many 280x Sapphire OC running spaced apart by a window that has been 0 degrees outside with a box fan exchanging the air and the VRMs are still overheating

And for those that may be confused VRM temps are not core temps.  Use GPUZ or another monitor for reading VRM temps.




Alright I took a couple screen shots for you guys.

Both rigs are near a wide open window with box fans exchanging air with the freezing outside.  The 7970 rig is at 80% fan speed, the 280x is at 100% and the 280x rig is also on the bottom shelf with access to more of the cool air from outside since it is a wire shelving unit and there is plenty of space below it for airflow.  Now if VRM temps are in the 100's when it's 0 degrees outside, what can you imagine it will be in the summer!!!

Also, the throttling isn't so bad on this rig (ATM).  The rig in the living room has hashrates throttling to the 500s because it is warmer.

Here is a system with last years 7970s.  All Sapphire OC
