post #3261 of 7589
Aquacomputer Backplate arrived today and i assembled it just now. While mounting it the watercooler lost contact to the card a few millimeters. Do you think i trapped air inside the thermal paste now?

What are your delta temperatures to water temperatures while running heaven? Im sitting at 15°C ∆ to water temp here @ 2050/1350 running heaven in loop.

Room 26° C, both cards don't exceed 40°C on firestrike/timespy loops, mostly stay around 35-40

+200/+500 resulting in 2050 clock

I will pay if i have to

If you modified it. They won't .

IMHO, much like the audiophile community, I believe that you truly believe you are seeing a difference, but that it is all placebo effect. Human brains are silly things and can not be trusted, not even your own tongue.gif

Personally, in modern times on LCD panels I cant visually tell the difference of anything above 30fps. 30fps "feels" off when I move the mouse though, and it keeps feeling off up until about 60fps, above which I can't tell a difference at all, and I couldn't when I was young and nimble either 15 years ago, when I had a 100hz CRT tongue.gif

I absolutely don't believe in scaling. The #1 reason I get larger monitors is for the extra screen real estate. Scaling the display completely counteracts that benefit. IMHO, nothing above ~100-120DPI makes sense on the desktop. For higher resolution a larger screen is the way to go.

IMHO, my 48" 4k screen is too big. It only results in ~92DPI which is a little bit too low to me. At 42" to 44" 4k would be perfect though.

I'm really going to limit this discussion as much as possible. There is a significant difference in the two things you mention. First is that medically/biologically, there are certain limits to human hearing that prevent people, no matter how trained or fine-tasted, to hear something. It's simply something that can be measured, just as human vision perception can be.

Now, the human vision. People don't see in frames or pixels, but there are time frames where people can see something and there are dots related to distances which humans can or can not see. To cut this short: humans can see a short frame even at high refresh rates above 200Hz. 240Hz considered the upper limit where people will not see flickering, even subconsciously. Every normal human can see a difference between 60Hz refreshed motion and 1xx Hz refreshed motion. Period. Unless you have a medical condition that would render you unable to see it, like some people do have issues with 3D, VR etc. As the refresh rate goes up from the 60, the change required for you to perceive it, is larger. You need a much bigger change to see it at high, than low framerates e.g. you'll easier see 30 to 50 FPS change than 100 to 165Hz.

Now, the resolution. Scaling is not something to believe in or not. It's also, like framerates and motion, science. Not something tied to personal preference. There is a term "retina" you may have heard, which is one of the terms related to human resolution perception and which says that at a certain distance and dot (pixel) density, you should not be able to see individual dots.
At a normal, 40cm distance from a display, the resolution of 2560x1440 on a 27" display still makes it possible to see individual pixels and jagged edges or lines. The point of high density displays is not to make it run at 100% scaling and have more real estate, but to scale content up to make text and other elements more clear and close to paper print (300 DPI usually). A 5K display exhibits a 217 PPI measure, still short of 300 DPI a printed magazine has.
By increasing the panel density making pixels and dot pitch smaller, our perception of the content improves. We're capable of reading smaller text and noticing tinier details at the same distance of the same diagonal panel we're looking at usually. With a 5K display on 27" you're able to see much more and finer detail than with a normal 2560x1440 display, at the same content, but scaled up to 200% making one content pixel be made up of 4 physical pixels.

DSR technology that Nvidia promotes and people tend to use to "try high resolution" has nothing to do with it. Higher fidelity of high resolution displays is a physical property and physical feat, not something you could ever simulate on a normal resolution display since all the benefits come from the higher physical pixel density of the display. DSR can only provide a better quality source for content sampling, but not much more.


Hopefully you'll read this wall of text and consider learning from it, not attacking it.

Instaled the hybrin evga 980 and the card dosnt work!!!! Oh god
Im uploadin some photo only the pump works the gtx led logo dosent work
Please help somebody






Please tell me you didn't actually install it with only the waterblock attached as pictured!?

That'd certainly explain why the logo didn't turn on, lol.

so i have spoken with electronic lab and they said that it can be fix
hopefully
just reinstated my gtx 980 and i can swar i heard my pc saying "are you kidding me!@!@!..."

in case they cannot fix it and the card is lost, just swallow the sore pill since you learned a valuable lesson here. You won't be so careless and daunting next time with a card of this value and stick to safer more proven methods of cooling like e.g EK blocks, read and follow guidelines better, use the plastic washers everywhere, don't overtighten screws etc.... I sincerely hope it won't cost you the card eventually to learn that but in the long run it will benefit you and the industry I'm sure so if it comes down to that just realize that all you lost was some numbers on your bank account wink.gif

I'm sorry to say I'd have to kind of side with Joker on this one. If you aren't going to go full custom loop and get respectable and tested full blocks from EK or aqua-comptuer.de, then stick with the stock coolers. Taking an AIO off a different card and going that route doesn't seem worth the risk.

I really hope you get your money back and nvidia doesn't read this thread !

Side comment:

So I was running more Fire Strike Ultra Benches and this time had the Power Limit displayed in the Precsion X OSD.

I have the power slider set to its max of 120% and + 175 Mhz on the GPU clock and +500 on the Mhz.

I was watching clock speeds and power usage (the temps are fine to me under the EK blocks) and noticed the cards seemed to max out at 2000 and then one card or the other would smack into the 120% (briefly would see 121%) and then one or both would rapidly drop down to 1975, 1987, 1974, 1962, etc. The highest I would see was 2000 and it wasn't sustained very long before that power limit hit. I ran FSU back to back in this config and got:
Run 1: 13817
Run 2: 13749

I really hope someone can crack the BIOS and let us crank that slider to 125% or 130% and not have to deal with strange PCB mods !!

I've been following this thread a lot!

I had two gtx 1080 EVGA FE in SLI and I just switched to one titan x pascal becase I noticed stuttering on my 4k television with SLI (also have a 165Hz g-sync). And one card is just way simpler IMO.

I installed AIO watercooling with kraken G10s on my gtx 1080. The first time I damaged the card (don't know why because I was really careful) and it wasn't even detected in my system. I had to RMA it and the reason I chose EVGA is because they have the best warranty. I replaced the original cooler and without a single question they gave me a brand new gtx 1080 FE without any fee (for this reason I will always buy EVGA when I can).

Now, titan X Pascal is from Nvidia directly and they don't seem to have a really good warranty... but it's not our fault if a 1800$CAN GPU has a cooler that SUCKS REALLY BAD. So it's totally legitimate to change the cooler...

I guess your best luck is to replace the original cooler as clean as you can and tell them the product was dead on arrival... it was possibly already damaged and just by changing the cooler it killed the card... who knows!

I hope you will get a replacement...

I just received my EK custom loop kit today. Will be installing my first custom loop this weekend!
I'm a bit stressed now that I see someone has broken his card...

The worn circles look like you gone in with a socket which is to big and pushed down to hard as you have unscrewed the hex bolts , damaging various parts on the pcb.


im not gonna send it to nvidia its Obviously and very noticeable that i have scratch the PCB so it gonna be waste of time
thanks guys for helping
i will send the card to the electronic lab and keep updating y'll

It's cool, I feel for you man, been there, done that!

Hopefully this place can fix the PCB for you...
