Which 780 Ti should I get? Asus DirectCU II OC or EVGA SC with ACX cooler? - Page 2

post #11 of 46

As for the variance in core VID.. its similar to that of CPU's. One might call a .8v VID for a stock 4770k.. "golden" .. though plenty of folks have gotten much worse. The same can occur  with GPU cores, and it has a direct affect on things like temps, power consumption and OC range. Point being... unless stock voltage is listed.. dont take 100% of what reviews have to say as 'gospel'. No 1 GPU core is the same.. same can be said for CPU's - 2x different sample of same CPU.. and one runs cooler/lower VID and can OC more.. etc.

 

OEM cooler... well...most of the coolers effectiveness ... or lack there of (in any case, not just these GPU's) is greatly determined by the airflow and ambients its subjected to inside of its new home.. (that being your CPU case).

 

*Most reviews test things on an open bench, where coolers have ample supply of fresh cool air... not exactly a 'real world' test.. but I suppose it provides some insight as what to expect when you start OC'ing the beast, or at stock.

Depends on what you prefer.

The DCII does have beefed up components assuming you win the silicon lottery and have a chip that can take advantage of that beef. However, with the DCII you're also limited to EK's waterblock only, whereas if you get the EVGA you would have a much larger variety of blocks to choose from, if aesthetics are important for your build. But, if EK's style is what you prefer, then the DCII is perfect.

Water aside, either air cooler would be enough for a decent OC as-is.

Ok, understood. thumb.gif

My main concern with Asus is that obnoxiously high VRM temps of ~100ºC, reported by Guru and some folks on the internet. If the card is hitting that mark at stock clocks, there'll be no room left for tweaking. I can't understand those temps, as the card has a custom PCB with 10 phase VRM. Perhaps it is the backplate's fault, I don't know... That's the only issue with this card. That and the fact that Asus has a warranty sticker that should block me from changing the stock cooler.

It would be really good if someone who owns this card (Asus) could chime in and report his VRM temps.

That's due to the VRM temperature sensor not being in the correct spot. ASUS has gone on record saying that we can rest assured that the VRMs are being cooled well within specs. It's just too bad that they just didn't make sure that the sensor was in the correct spot. After all, didn't they know that we'd want to know what the VRM temps are? lol

I dont own the Asus card..but I am modding a sample that has been tested on stock cooling though by the owner (a reputable member here on OCN). This particular GPU had a default boost setting of 1300mhz and completed an array of 3D benching at those speeds, on the stock cooler without issue. While I cannot agree more with Nuclear's comments regarding the 'silicone lottery'.. I will admit that for the most part in the past, EVGA has been a good choice for good performing cores... though the power circuitry on their top-tier GPU's is not always sufficient.. or up to 'par' when compared directly  to other brands (be that Asus, Gigabyte or Zotac)...and while the premium power components do NOT promise a premium core.. If you did.. its sure hard to OC a good core, very far without them. ;)

Let's hope for that. I don't mind having more from EK inside my case, I think it would combine with my EK Supremacy in Copper/Acetal. I just don't want the CSQ version. One thing is to have those circles on a small area like the CPU block, other completely different is to have them spread all over the giant PCB area of the VGA. smile.gif

Really? Is it really that simple? Shame on Asus for that, of course we want to know what the VRM temps are!

Btw, any info regarding the warranty sticker? I've just read about that on a ROG forum, so I'm curious if it is true or not. It'd better not be.

Good to hear that. I'm much more confident now about the card. Let's just hope I get lucky and get good cores to go along with the premium components towards a nice OC. smile.gif

Yeah, unfortunately it is that simple.

Ok, thanks. wink.gif

So, I've made my decision of getting the Asus card. I should be ordering it tomorrow and will probably receive it by Monday. I'll then update the thread to let you guys know what the card is made of and to give the info about the warranty sticker.

Thank you. +Rep for you all!

I could have purchased the Asus DC II 780 Ti for $530 a week ago, and didn't pull the trigger. doh.gif

Waiting for that deal to come around again.

The R9 290 isn't far behind the 780 Ti, and you can get the DirectCU II for $489.99 shipped right now.
