The RX Vega 64 Owners Thread

OK Vega 64 Nitro watercooling update.
Since I had some issues with the Predator 360 today after putting the waterblock on the Nitro, thought it was the block.
Even if I was filling it up, everything was overheating even at stock. (CPU included)
And since the Predator doesn't have anywhere any clear waterflow diagram, thought I put the QDC connectors on the GPU the wrong way around. (it has clearly IN and OUT flow markers).
So had to drain the block and retry again.

In the mean time decided to remove the block and see first what happened to the Predator..... Yeah. I was filling it up alright but not fully -_- After tilting quite a lot while working managed to refill it properly.
By that time I had put the original heatsink on the Nitro. (but the block is filled up now might re-install it next week).

Few things from deliding the Vega 64 Nitro. The thermal paste was rock solid like it was there a decade. And is one of the new cards manufactured around Computex.
Doesn't like liquid metal on air -_- True temps are better, BUT it relies on certain temps to be hit to turn on the fans. So one moment you run Spy at 48C on 0% fan and next moment it spiked at 55C the fans kick in and system crashes :P

On just Turbo mode temps are even lower than before and the fan doesn't work as all while benching clocks also are fine.

Lol I'm gonna be using a spare GTX 1060 I have here in the meantime so yeah kinda. I won't buy brand new Geforce again though. Buying second hand Nvidia feels more er humane. Like buying an old fur coat instead of getting a new one made. You know it's wrong but it's better than buying brand new xD

Hopefully when AMD have something new out I'll be able to afford it ! Am skint right now lol.

Those predator aio's seem to be a nuisance, seen a lot of complaints about them, which is surprising considering they're made by EK.

I hadn't an issue for 18+ months I have it. Plenty of hardware used with it (6700K, 1800X, 6800K, back to 1800X, 8600K) and pre-filled waterblocks (Nano, GTX1080, FuryX).
However is a damn annoying there is no fricking diagram of the flow :mad:

So whole world broke loose because

a) My Nitro waterblock (not made by EK) has a direction IN and OUT. So clearly I cannot put the QDC as I see fit. But without diagram kinda stuck.
Spent hour trying to find out the flow, and used the Nano as an example of how to put the plugs. That didn't seem to work, so I had to drain and move the plugs the other way around.
But :

b) Given the size of that behemoth (Predator 360), didn't want to dismantle the whole system, so used the side plug to fill it as per instructions. However while it is up to the top in water/liquid the loop was in low water even of it was full at the plug. :mad:
Videos and manuals and EK support told me to use the side port (as the rad is horizontal) if I just top up. But clearly that's not the case. The loop was missing half litre of liquid.
So at the end I had to dismantle everything, tip upside down the predator and start putting water from the bottom plug. Then move it around and keep going. Yet still after 1 hour with the CPU alone the side plug needed topping up :mad:
If I had normal loop I would know which direction the waterflows, and how much water is missing.
But is ok :)

Also figured out why the Vega 64 was crashing on stress. The liquid metal reduced the temps by a lot. So the 7% overclock was trying to push the card to 1800 core, from previous 1727 at same setting (hahahah :D)
Why I use the slider? Somehow i get more stable overclocks with the slider than setting straight speed at P7.

Also now, on benching, half way on benchmarks the temp drops to mid 40s after the fan has kicked for few seconds at 100% speed so it turns off the fans while still half way the graphical benchmarks! Which is kinda annoying because I have the bellow setting on the damn Wattman and should at least work at 2500rpm not go to 0.

Don't get me wrong I love all these challenges with the V64, that is why I am saying for a month now, and why the GTX1080Ti Xtreme was a boring and no sport.
(didn't even bother to overclock the Xtreme, :o but for what 40Mhz core over factory overclock?)

I know can tame the card when put under water. grrrrrrr :p

@LtMatt some help with the fan speed settings? Why it drops to 0 when minimum is set to 2500 half way the benchmark?

Why is 0db even a "feature" on some cards? The fans stay spun down till it hits a gaming load then they spin up, but at idle they spin so slow they can't be heard anyway. Just seems like another daft thing they can slap on the box as a checkmark feature.

I agree on that. I mean yeah is nice to have a dead quiet card etc. But even at 2000rpm the Nitro+ is more quiet than the Predator 360 at 50% and the system fans which generate a normal hummmmmm. Also is completely un-audible when playing games or listening to music even at 2500rpm. At 3300rpm yes can hear the card, but usually that happens on benchmarks and FC5 :p But who cares that moment when you have 20 people shooting at you :p

@AmateurExpert mate THANK YOU. :D That should be the issue. Damn Vega64 guides.
Some people have no clue.... (including me still). :o
 
I agree that all fans have a speed below which they're practically inaudible unless you are in an unusually quiet environment like a recording studio; there will always be some who care about silence and don't realise that slow fans are quiet enough. There is a little merit in not having fans spin to save on bearing wear and slow down accumulation of dust on the heatsink, but these advantages are slight to say the least.

Anyhow, the Nitro Vegas do look nicely built, and would be on my shortlist if I was looking for an air-cooled card for another build.

I did wonder also. That "dirt" is impossible to be washed out :p
For penance should own an AMD card for the next 10 years straight :p

Lol boys, I'm fine with using older GPU's I already have. I will never buy a brand new Nvidia card, I am the same with Apple. Just will not fund them anymore. To many ethnically / moral reasons to not buy them. Each to their own, if you have no problem with them than that's fine with me.

On the subject .. Wait until the you see the prices of Nvidia's next gen stuff. Even the most loyal fan boy will struggle to swallow it xD

Yep you can bet it on. The moaning of the initial GTX1080 & GTX1080Ti pricing which wasn't that loud just died over.
Next one will be even louder. But NVidia has given them the incentives to buy one....

I was fiddling with downvolting and found some peculiar things.
a) Losing 100W from heat and power consumption from Turbo mode, loses you less than 10% perf. Went from 280W to 180W fps drop from 110s to 100s the FPS on the game i was running to test these.

b) Losing 180W (half) from heat and power consumption on custom overclock at 1742, loses you 15% perf. (from 360W to 180W).

c) If clocks are left alone, and drop from P7 from 1200mv to 1000mv, and P6 to 990mv (the clock near the memory dropped to 990 also), keeps the same high 1500s clock.
However if clocks are set to -1%, the performance and clocks remain the same, yes the power consumption drops.

d) If the default powersave mode is used, it drops to 180W as before, but the performance plummets by 40%.

e) There is some voltage "step" at 940mv. Any bellow that, and the performance drops faster than before but power consumption remains the same.

I will keep experimenting with the Nitro+.
 
Update on my experimentation, due to looking how to heat less the room these very warm days.

I have moved the card all way to 110W power consumption and the clocks just keep dropping very slowly. Only note bellow 930mv P6/ 940mv P7 the card drops HBM VRAM to 800 from the stock 945.
At 120W (from initial 280W) the FPS in WOT is as follows.
280W 110-120 range.
180W 98-105 range.
110W 85-95 range.

So for 2.8 times more power the FPS growth is just 30%. Not bad at all.
On games like EU4, CK2, the power consumption by default was already at 76W that hasn't changed. (update, add to the above list X3AP and X3TC with graphical mods installed, power consumption is around 60W with the fps cap at 143fps)

Does anyone knows a good graphic game/benchmark that we can take as a good example so I could create a graph with my findings?
It has to be graphic heavy game, like Crysis 3 maybe?

Finding some funny things with battlefield 1, was flying with a plane earlier on sinai and noticed large grid patterns on the sand when using my titan card, hadn't seen these at all with the vega card installed. Will try and get some pics tomorrow, pretty odd looking regardless.
