ASUS HD 7970 DirectCU II 28nm Graphics Card Review
- Details
- Written by Evan Hiner on March 01st 2013 at 12:09am
Now seeming as a traditional staple of ASUS' non-reference product stack, their DirectCUII graphics cards have been well-received because they enable high performance without the acoustic footprint. A 3-slot beast of a cooler allows only two 100cm fans to reduce thermals on the GPU by 20% while remaining 14dB quieter than the reference cards. And while the DirectCUII technology brings along with it a prominent lineage, so too does the packed feature-set that comes in the box, both inside and outside of the large aluminum shell. The 7970, the first GPU based upon a 28nm architecture is at the top of AMD's single-GPU product stack and supports AMD's EyeFinity technology with up to 6-display capability.

Unboxing and Included Accessories
Out of the box and neat internal packaging will emerge the beastly ASUS 7970 DCUII, the typical user's manual and driver CD, 4-pin molex to PCI-e power cable adapters, a DVI-to-HDMI adapter, a CrossFire bridge, and an additional VRM heatsink to accommodate an LN2 pot. A pretty basic loadout for a card that is anything but basic, so let's get into the juicy details.

It's a huge issue on these models. To be straight ti the point: http://www.xtremehardware.com/recensioni/schede-video/arctic-cooling-hybrid-7970-pt-ii-test-accessori-e-confronto-con-asus-7970dc2t-201211157843/?start=10
ASUS DCT2T, 60 degrees on the core and 100 degress on the VRM section. That's a huge amount and this is why they limited the Over-Voltage capabilities. If being overclocked at 1GHz with 1.112mV it generates 74/112 degrees celsius for core/VRM
note: che first setting it's blank due a graph error but as you can see in the other images it's "ASUS HD7970-DC2T-3GD 5 AUTO/40%, 1974 RPM"
The 7970, as it's shown in your review, it's a very solid performer. Good day
please avoid missinformation
Hi Ivan
Show me something, a link to an Asus Statement or something like that. I've never heard of such clarification, would you be so kind to show it ?
If you're right, this should mean that eveery VRM sensor mounted on the Gigabyte and Asus, or even 7970 reference designs, should have some issues. As you can see from the graphs, ad stock speeds it's all right for gigabyte 797OC-3GD but if overclocked it behaves similar to the Asus one.
Have you made personal tests that proove that the sensors are broken ?
What I've posted it's what I've seen also on other designs, not only Asus and if you check the ROG forums it's full of reports, like this one (7950 DCII model, faulty design): http://www.behardware.com/news/12153/asus-hd-7950-directcu-ii-fault-report.html
It's not a ''rumour'' if it happens to an entire comunity ;)
Another link, HWINFO program tells the same story (it could be obviously the same sensor, but it's not a software related problem): http://hardforum.com/showthread.php?t=1670759&page=22
In this lik there's a person which states what I've seen on my test lab, Gigabyte 797OC-3GB capable of heat the VRM section at 65 degrees with the stock settings.
I suggest you to read carefully hte review, the Arctic Cooling accelero Hybrid it was installed in the gigabyte 7970 797OC-3GD not the Asus DC2T.
I suppose that you're referring to the Core temps, since that GPU Tweak only reports it, and it's perfecly in-line with the temperatures reported in the review.
Before stating that what I've done is misinformation, please let us know about what you're talking about.
Many thanks in advance
