I just tried running the mem voltage at stock 1050mv at 980mhz and my system just crashed 5 seconds in firestrike lol.

Different chips i guess or your power sliders a bit lower than i had mine , i cant overclock memory at stock volts without nudging the power slider up.
I haven't yet touched that voltage though , like i said it's not known to stabilise higher clocks.

Like i said i can clock memory to 1100 but what i didnt mention is that 980-1000 i couldn't get stable at all at any point ,1050-1100 24/7 games fine etc

power limit slider was set at 50% which is the "max" you can do on wattman.
Here is my setup which i'm probably going to leave alone now as i am pretty happy with the results. According to HWinfo64 the GPU chip power topped at 311w which if i am reading it correctly is lower than the turbo setup which is at 345w?

All good mate. Wasn't critisizing just passing on what i heard and learning more.

Trouble is no-one wants Vega64 just because of the price vs performance against the 1080 and power consumption. Lot of reviewers etc are ignoring it and focusing on the 56 more.
I'm struggling to find things about the 64 tuning etc from other people and i guess people are waiting for better cooler too.

In the last few days I did not get much time to try to tune my Vega 64 further.
I got other projects going on.

I got problems with PSU, as I mentioned here:
https://www.techpowerup.com/forums/...urning-on-pc-by-pressing-power-button.236818/

My new Corsair HX1200i should arrive tomorrow, hopefully all will work fine again with the PC.
On the bright side Cosair HX1200i offers monitoring of power draw on all the lines so I can measure power draw of Vega more accurately.

Furthermore, I delided 7700k yesterday and changed thermal paste under IHS to Thermal Grizzly Conductonaut and also changed thermal compound on Vega from IC diamond to Thermal Grizzly Kryonaut.

People told me how IC Diamond should be avoided as it could cause damage to the card. Here is the related thread.

Should be interesting to see how a change of thermal paste affects the temp on Vega.
Just played Prey for an hour at the beginning at maxed settings with freesync enabled(72hz) and the framerate has not dropped once at all. Temps was hovering around 69-73C while GPU load was hovering around 60-90%.

Vega64 is good but not for that price. At $399 it would totally be amazing.

Let's hope Vega11 and Vega20 gets better.

Why 1100mv for memory its not noted(not just me many review and oc guides) to either do much or stabilise memory , with stck memory volts im good upto 1100mhz game stable and mire volts doesn't change that top limit for me atm.
My best oc varies 1729-1751 core 1100 memory GtaV etc stable ,i run it lower to save power though.

my guess is that at some point you're going to experience crashes or some sort of performance degradation (stutters most likely) due to that memory OC. there is a chance you just got extremely lucky, but it's too early too tell. i've messed with three Vega 64s, memory would not stay stable when OCed at stock voltage. i had to go to 1100mV every single time. some pro reviewers had to go further. guru3d had to go to 1200mV to get 1060Mhz on the memory

and second, those core speeds are useless because at that point you are pulling about 350W just for the GPU. those extra 1-2 FPS you'll get in games are not worth it. the best performance scenario for vega 64 is to undervolt as much as possible while maintaining stock clocks to cut power draw. personally i've shaved nearly off 60W from total system power draw doing this, bringing the card's draw to 275ish, something I can live with. but i will not live with 350W. that's just ridiculous.

For sh*t and giggles here is my comparison score on heavens benchmark between my Rx580 vs Vegas.

 

[turbogear]

Here is a video from @buildzoid on undervolting RX Vega.
Thanks a lot for making this. It would definitely help some Vega owners here.

Thats undervolted to 1.18 , so slightly and I said I don't game or run it with that much power use it's just a bench oc in reality and I can do better im waiting for reasonably useable oc software maybe some bios tweaks or useable power play tables.
Mine is on 24/7 @ 1340/1100 core mem clocks at 1V on the core and it's not getting above 42°C , it's fine and at approximately 240 watts.

how do we upload the vega 56 bios to tpu?

I cant seem to find the tab on gpu-z

This fucker clocks well with no voltage added at all..

 

[fullinfusion]

Sorry I posted this in the wrong thread so deleted it so pasting it here where it belongs..

What's the typical HBM2 on the 56 able to run in frequency with no additional voltage?

I only had 5 hrs of playing time with my Vega 56 on Friday and didn't push it to hard. Managed *edit* +4% on the core so stock1590 to 1652 and 900 MHz on the memory.. then was to tired and went to bed but it was rock stable at stock voltage..

Im happy it has absolutely ZERO coil whine with this card unlike what the reviews were saying, it's a real quiet card

But man did the performance ever jump with that small bump infrequency

One of my games I always play was maxing out at 143.9 frames per second lol.. I had the frames in game settings set at 144 for freesync and was totally amazed how well these cards perform plus had all settings on ultra and one other on insane ( only one with it)

 

[MrGenius]

Watch the vid in post #110. Around the 7:50 he starts the explanation of why Vega has no "real" memory voltage control. You need to watch until he finishes explaining it around 16:30.

And in the beginning(during the first 4.5 min.) of the vid below he says Vega 56 tops out around 950MHz HBM with 1.25V(which is stock, and isn't "really" adjustable). And should be able to get ~1100MHz with the Vega 64 BIOS and 1.35V HBM. Note the vid below was recorded before the previous vid(so he knows more about it in that vid).

BTW...coil whine has nothing to do with performance and doesn't gain you anything one way or the other. So saying the card is "good" because it has no coil whine is misleading. It's quiet. If that's what you want to call that a "good" thing...fine. Just specify that's why you think it's a good card. Stupid people will think no coil whine = good performance. When they aren't related to each other in any way.

 

[fullinfusion]

Besides I have better sources then you may think

Well straight from the horse's mouth, and I didn't need to wait till tomorrow, these chips are all the same. Only first run reference boards use the exact same parts so now I feel better about flashing the v64 bios and not killing it.

Time to get my flashing tools out

 

[T4C Fantasy]

does anyone have the silver limited edition? please gpuz shot that

Vega 56 = C3
Vega 64 = C1
Vega 64 Liquid = C0
Vega 64 Limited = ??

 

[fullinfusion]

The limited is the exact same card as the regular V64 card. Only difference is the shroud

Edit:

Oh sorry didn't notice your the updater.. how about updating the pictures in the data base so not to confuse people on what bios is what.

Another topic.. I see the Asus Strix V64 isn't such a good card. Apparently the reference card beats it hand down as it can't maintain the clocks like the reference does despite Asus having a better cooler..

I've never had any luck with Asus cards in the past.. every card from them were slower then MSI, Sapphire ect.. jayz2cents on YT has a good video on the card and he's even like wth!

Anyone having problems with wattman not saving profile with 17.9.2 drivers? Mine keeps resetting back to balanced after shut down,would it be because of stability or is it because i turn the desktop off from mains?

Haven't noticed it on mine tbh.. if anything it holds the preference.. especially if I hammer the memory to hard and it locks up.. wattman won't pull it back on its own after a reboot..

Have to hit preference and then reset to default to get it to default back so not to crash again..

Edit: if you OC the card or change the last 2 P states voltage and you have a crash be sure to check the voltage after a reboot.. some systems are jacking the voltage higher.. only fix ATM is to increase the core slider bar to +3 and then hit reset and that'll bring the voltage back to normal.

Have you got afterburner loading at startup , it can auto reset the wattman profile.

 

[fullinfusion]

No I'm beta testing wattman drivers only.. I could but then there's to much conflict going on.. once the hotfix comes out I'll test AB

I've only undervolted the last 2 state voltages and haven't had any crashes at all.

I do have afterburner loading up at startup but i thought ticking the option in the settings in afterburner stopped resetting the crimson wattman profile to default resolve it? It worked on 17.9.1 but after installing 17.9.2 it appears it doesn't work. I'll have a go at disabling auto start-up on Afterburner.
