That Voltage is a Little Too High Bro

[afyeung]

Definitely not trying to call out anybody, but 1.6v on a 290x is impossible with temps of 50c. You need ln2 to be even close to that range. Just making sure that accurate info is posted to the gpu oc datasheet. 

 

Edit/fyi: His stress test was quote on quote "far cry 3 and other games" so not a short bench. If you guys have followed the 290x, the price to performance legend that happens to be an inferno, its temps get crazy high after you bump up the voltage. Even for a short run you need ln2 for those voltages. 8 pack got past 1600 core I believe on 1.6v. That was one of the fastest gpus on the planet at the time and still is. 

 

2nd edit: http://www.overclock.net/t/1436497/official-amd-r9-290x-290-owners-club/4030 with those temps at 1.6v you would be drawing 630+ watts on the pcb. Maybe do- able on a lightning or matrix edition card, but definitely not a reference pcb

"AquaComputer with Active XC" sounds like a waterblock/loop to me, but we can't see if that's under cooling.

[Briggsy]

its a bit high for 24/7 use, but still within the realm of sanity for extreme benching. in a short bench run a max temp of 50C is possible if watercooled, which that card apparently is.

It is water cooling lol. 1.6mv is what 8 pack used to break world records with his 290x under ln2.

Probably a typo or something.

His stress test was gaming. And its just impossible to maintain those voltages with those temps. With a modded bios if you could get that high and maintain 50c, you would literally blow up a reference 290x.

1.6v*

 

 

50c at 1.4v or so on water is doable if water is cold, but not 1.6v, that's DICE and Ln2 territory.

Yep. Thanks for correcting me. I had a brain hiccup and though that 1mv was 1000v instead of 1/1000v

I have seen setups on YouTube with radiators positioned outside in near freezing temperatures, and frosty temps on the gpu. I can't say what the temps would be at 1.625 volts in that setup, or that the tester in question has that kind of setup. If they do then mystery solved. If they don't then like you say the card is gonna fry.

I have a setup just like that, and if he really was pushing 1.6v through his gpu, his core clock would be much higher than 1250.

 

 

1250 on a 290x @ ~1.25-1.3v on water would be 50c or so, that seems more plausible.
