Is that at 1080p or 1440? Seems quite good boost in those 2 games.
I would love to buy a i7 8700k, but I can't justify it as I'm currently on 1080p 60hz and next monday will be moving to 1440p 75hz freesync,

1440p mate

Anyone have any info on the GPU Hot spot?

According to GPU Z whilst gaming for a few hours Max temp gets to 91 degrees. Have fan speed set to 3600 max (I wear headphones). HBM only gets to 83 degrees...

Is GPU -Zaccurate? Normal for Vega? Faulty card?

Reaching just over 1600mhz on stock settings.

The hot spot is between the HBM and the GPU by all accounts and it always runs hotter than either. on an air cooled card that sort of temp isn't unusual. Go AIO mod.

silversurfer · 9 Dec 2017 at 11:10

Sounds normal, whats the case temp at. Add a couple more 120mm fans so the vega has the best intake temp possible otherwise it needs stronger cooling fitted. I dont believe it causes any negative personally, the heat paste will need changing at some point most likely.
The stock fan setting doesnt always use the full range, upto 3900 rpm is still ok and upto 5k rpm you better be playing a noisy game with good earphones or something which I do and I dont hear it personally

This just shows how crap the default settings are.
My maximum fan speed is 3000 RPM and I get way better temps.

Finally cracked 26k,that's me happy now.
I used an lc to get there.

Hi fellow red teamers

As for the GPU-Z temps etc.
Has been already discussed here, but still....

59 00 (89°C) USHORT usSoftwareShutdownTemp; For AIR cooling a.k.a reference designs.
69 00 (105°C) USHORT usTemperatureLimitHotSpot;
49 00 (73°C) USHORT usTemperatureLimitLiquid1; For liquid versions. 73C on the core. all the rest should be the same (HBM and VRM etc.)
49 00 (73°C) USHORT usTemperatureLimitLiquid2;
5F 00 (95°C) USHORT usTemperatureLimitHBM;
73 00 (115°C) USHORT usTemperatureLimitVrSoc;
73 00 (115°C) USHORT usTemperatureLimitVrMem;
64 00 (100°C) USHORT usTemperatureLimitPlx;
40 00 (64Ω??) USHORT usLoadLineResistance; No idea what that is really

Meaning that the if the core is over 89C it will shut down or throttle seriously . (AIR)

Hot spot limit is 105C. that I have reached. It either crashes and resets your OC or sometimes hangs for good.

HBM2 starts throttling if it reaches 95C.

From my experience: if the "hotspot" reacher over 60c (already) it will start turning your clocks down. I have tested this. With my 2x360m MAYHEM monster rads i can achieve this for a short period. I have serious OC-s also, nothing near stock. But after it crosses 60C, it begins some minor downclocking....after that it does some SERIOUS downclocking with the temps I described or shuts down. Had that when i was still using AIR stock coolers.

Hope it helps anyone

Take care!

Davedree · 9 Dec 2017 at 12:36

Yeah def around 60c I see clocks drop 10mhz or so and then at 85c heavy throttling like my polaris 470

If you think 3900 RPM is okay then I'd really consider going to the doctors.

I've got mine currently at 75c core maximum at 2800 RPM.

That's at 1025mv and I'm pretty sure I can get that down more.

Almost exact to what i get on the Lc bios for my 56 (with Aio)
Good stuff champ

There's my Vega settings.

That will max around 75C. I don't see any throttling.

I could gain about 10% if I smashed voltage through it to increase the core clock but it's pointless. at 2800RPM my card is solid.

Hello,
Using 64 LC but cannot get past 25000 gfx score firestrike points and maintain also a stable overclock. Viewing matt's and iucidium score's and trying to see whats wrong. Are you using wattman or overdrive? At 17.11.4 drivers atm.
Care to share any settings stable oc? Also HBCC on or off?
Thank you guys!

gupsterg · 9 Dec 2017 at 22:19

@Kei

Ahh did not know you had V56 flashed to V64.

@Illuminist

Last time I checked the VBIOS in zip is latest for ref PCB V64 AIR, reg file works for me on v17.11.4. The file is stock, in OCN thread is the reg file editing tool which I included a screenie in zip.

@Davedree

Nice result

.

jimpsar · 10 Dec 2017 at 15:13

My best for firestrike

https://www.3dmark.com/3dm/23879741

clocks stock, -20mv
1105hbm/950mv
Power +20%
Hbcc on

Trying to get at least 26000 gfx

nashathedog · 10 Dec 2017 at 15:29

Gigabytes Vega card.

https://www.anandtech.com/show/12131/gigabyte-unveils-radeon-rx-vega-64-gaming-oc-windforce2x

Looking at the card breakdown picture I hope that's not what the heat-sink really looks like as it'll be too thin to cool Vega.

Gigabytes 480 and 560 were both poorly made cards and this looks like it's going to keep them consistent if nothing else.

Possibly one to avoid.

Use a more demanding bench, like timespy Extreme, Firestrike Ultra, or even Extreme and use that as a comparison for performance.

Standard results can vary a bit as its not as demanding and you have other limitations which can affect score. You can already see that some of the highest Vega G scores come from using lower clock speeds in Firestrike Standard. You won't generally see that in the benches listed above.

Might not be the right thread for it but how do the Frontier Edition cards stack up against the competition with the newer drivers?

shankly1985 · 10 Dec 2017 at 15:31

If they was a online game to show of "smooth" It is Battlefield 1

I wouldn't recommend buying a Vega FE GPU if your main aim is gaming. Gaming driver optimisations and bug fixes via drivers will be delayed in comparison to Vega gaming SKUs.

Vega gaming SKUs will get frequent updates, 2-3 per month as required. Vega FE may only see driver updates every few months.

Thank you for the prompt reply. Okidoki, thank you and understood!
