Could be over temp protection triggering at those temps - 220F+ is pretty hot if you ask me.

I've heard VRM temps around this are normal though even made for to cap at 125 celcius.
post #14773 of 38701
Two questions:

1. With a factory-overclocked non-reference 7970 (Sapphire Dual-X OC), is it worth trying the Gigahertz BIOS if the card already runs at 1050MHz on factory settings? Is it mainly for better video memory settings to consume less power or some such? All the reviews I've seen seem to indicate higher power consumption for the GHz BIOS 7970s, but that might have been vs. reference cards.

2. I'm using 12.7 beta driver, as I had a very positive experience with it using an HD 7870. Is there any improvement with 12.8, or mostly a wash?

Just leave your overclocked speeds via software and stick with 12.7 because 12.8 are unstable for many users.

I would really appriciate that! biggrin.gif I haven't crossfire any setup before, so I thought it sound like a smart idea to mix two great cards!

Im looking to sell 2 of my 3 7970s all 3 have an asic of 80% + I want at least $325EA or I will do $600 even for both and may do $550 for both . It's according To where I have to ship it to . I still have both the boxes they come in and can take pix on request . It will be shipped in the same box I got it in .

I may end up selling the other to for the same price im getting out of pc gaming and getting a laptop . I'm in dire need of the money , my grandpa passed away I lost my job and I just need the cash I have a ebay account but I really dont know how to go about selling it . When I go to sell everything I have a MSi Big Bang Marshall and a Intel 2700k cpu 16gb of Gskill ram and lots of other stuff . I have a DoubleSight 30" I payed $1500 for and I want atleast $700 For it it is hardly used and in real good shap . I will sell my whole computer screen and all for 5k also has trifire 7970 msibigbang marshall and h100 water cooler and 16gb ram Intel 2700k CPU this includs my logitech g19 and logitech g13 and my 30" screen

Hey I just noticed 12.8 drivers are available for download

seems like they skipped the whole 12.7 and jumped from 12.6 official to 12.8 official

has anyone try them yet?

--- EDIT ----

never mind, i just read the messages above tongue.gif

My main GPU Temp lingers around 75-80 during this so It may have something to do with the VRM Temps for #1. I stopped it early, because of the huge temp differences between #1 and #2 and my system was on a verge of another system hang.
Edit: Decided to let it go fully and the VRM temps for #1 caps at 115 Celcius lingering to 113-115 and if you leave it for like 15 minutes it crashes. This is with the main GPU Temp to be at 80 degrees Celcius and the 2nd VRM Temps to be at 78 degrees Celcius.

yeah thats what is making it crash thats way to hot imo

have you tried removing the cooler and checking the pads ?

Lol. I just tried my VRM temps again as well after they overheated during a few hot ambient days here.

For the ones that didn't read that: Using a reference 7970 with a Accelero 7970 - fan module and with 2 Slipstream 1600RPM fans tied to it.
VRM sinks of Arctic are just way too small, and the thermal tape self-mix goo is rather bad as well. With a voltage of 1.243v and 1230Mhz core, 1.625v VRAM and 1700Mhz VRAM I hit well over 100c in BF3.
Also, Heaven 3.0 on all max could pull it pretty high, but not as high as BF3. Current load was about 140-160 amps in BF3 max.

Tried them at those clocks again now that ambients are back to 20~ish deg. celsius. Roomtemp was like, 21c now.

Ran Heaven, somehow VRM's stayed REAL cool, only 66c for VRM1 and 54c for VRM2 in GPU-Z. Current draw was pretty low, only averaging about 124 amps.
So, I decided to REALLY test them with something that pulls EVEN MORE amps and load then Furmark does. OCCT.
That managed to pull a figure well over 200 amps quite easily with the average current being about 223 amps. (VDrop was quite extreme, it did artifact lightly due to it)
Well, that load on the VRM's caused VRM2 to behave very normally and slowly go up to about 65c and staying there, but VRM1 just SHOT up like a rocket and within 60 seconds it had reached 105c and seemed to stabilize there but no, every 5 seconds it would climb a degree and every 4-5 degrees VDrop increased till the point OCCT just died with the VRM1 temp at about 128-130c.
So, This Arctic heatsink is VERY good in terms of core temps, only 65c even with 200+ amps (240-260w) on it, but the VRM sinks are severely worthless. I'm going to find a way to cool them better.
