Bit of a long vid and I don't understand German but fits a new waterblock on the Rad VII with some benchmarking.

The machining doesn't look very good at all on the die area. You can clearly see machining marks!

MeddlE · 25 Mar 2019 at 17:56

So the Bykski works out to what, £90-100? Uses original backplate.
Ek is £130ish? plus £40 for a backplate.
Alphacool is £115 and includes a functional backplate.

Hmmm.

The video is interesting in that he left 2 sprung screws out on the 4th row from the front of the GFX card when he was looking to fit the original back plate. have to agree that the machining looks very visible but is highlighted by the high gloss reflective coating.
have to say the temps were quite impressive even so, especially giving it 1.2mv plus! I will look closely at mine when it arrives tomorrow after paying the customs charge. but do like the idea of using the original back plate.

Have tried out my Radeon VII on air and normal watercooling. Tested with 7700k at 5ghz 4.2cache 3000mem with bad timings. stock voltage for card is 1031mv.

On Stock air it does:

1801/1250 with Uv 905 MV FSX ,Fs,3dm11 etc stable. avg clock 1750mhz core / 1250mem

score FsX: 13950 gfx points (140w highest power peak). 0% power. junction temp 75 load degress.

Max clock on air it does:

1970/1250 with 1008MV FSX,Fs,3dm11 etc stable. avg clock 1920mhz core / 1250mem

score FsX: 14925 gfx points 5% power. junction temp 98 load degrees

Well since card was so hot in temps with low volt i removed stockcooler and mod and Ek supreme Hf cpublock for watercooling. Suprice no contact nearly with pad. Was like 20% of pad had contact. Was no residue on silicon of graphite pad.

With watercooling mod and 28 deg water temp it does:

1801/1250 with Uv 896 MV FsX,Fs, 3dm 11 etc stable

sore FsX: 14297 gfx points (130w highest power peak) 0% power junction temp load 34 degrees

For same setlings as max air (stock) under water.

1970/1250 with 980 MV stable 5% power. 50 degrees junction

score Fsx: 15324 gfx points

Max clocks under water.

2200/1250 16502 gfx points Fsx 1190Mv 55% power 74 degress junction temps. Real avg clocks 2150/1250. About 390-410w avg gpu power draw.
2200/1250 34600 gfx points Fs 1190Mv 55% power 70 degress junction temps. Real avg clocks 2155/1250. About 380w avg gpu power draw

Tested with some Tess tweaks Hwbot.(No other tweaks like LOD and windows setup etc)

Same clocks volt power etc:

FsX: 18335 gfx points

Fs: 37530 gfx points.

Think any higher then avg 2150/1250 avg clocks is hard with ambient water. 2200-2400 we nead chilled water for or colder like cascade/Ln2. My Radeon VII scales with colder temps on voltage nead at stable clocks. 20 degrees lower junction netted in 230mhz higher stable core oc. Highest Air stock oc of 1970/1250 neaded 1008mv on air but on water 980mv. Then water had higher avg clock from same settlings set in wattman. So 30-45mv less voltage on same avg clocks.

Turned into a costly block getting stung by customs. 20% vat plus a handling fee? I've gone with the alphacool block. Quite like how the backplate clamps the whole card together.

not to costly really, block was $85 plus 11.27 customs charge, so all in 93 quid so not bad.

I had a promo code for my block too so turned into £110.66 delivered.

How do you get 1250mhz memory when it only goes to 1200?

Thanks for the detailed undervolt/overclock results! I reckon a watercooled Radeon VII could be worth it if it performs between a 2080 and a 2080 ti (FP64 performance and 16 GB of HBM2 is enticing too).

This is what has miffed me regards the EK block, Their RX56/64 block would accept the original back plate, why on earth have they decided no to do the same with the VII?

Seems daft that any manufacture does this if the original card comes with one, especially if it's the reference that has one by default.

@Gibbo Any clue if OCUK will stock the Bykski VII block? They don't seem that popular over here. I nearly pre ordered a EK block but OC don't list the copper+plexi anyway.

Pulse88 · 25 Mar 2019 at 22:56

Did an run with test rigg on Fsx. Without any tweaks. 5.2ghz on 7700k on water. Real avg clocks 2140 avg core on 28 deg water temp and 74deg hotspot.

You nead to mod powertables to max Radeon VII on water or better cooling. Thread over at overclock.net. i use MorePowerVII_77 when watercooled in ambient. Can likly go higher on core and hbm with other regmods. Will have card waterchilled first before going to the heavy reg mods.

When radeon VII are clocked at 2130-2140 avg core is it most likly faster then 2080Ti stock at games. Seen youtube reviewers got tied with 2080Ti already at 2060-2080 core set clocks in many games. My guess those cards are avg at 2010-2030 core. All cards oc different. You likly want an card with god Uv on stock clocks to hit high clocks on normal water cooling. 1018-1032v seems to be top bins on Radeon VII. To find out bin voltage use gpu-z check gpu volt sensors when running gpu-z load test.

Its alarming how big of a range the voltage binning is on these cards! Thanks for sharing the table!

Why does wattman reset my computer instead of reseting the driver when I mess up my overclock now, am I doing something wrong?

What do you mean by reset your computer? All WattMan will do is restore any changes within WattMan to default in the event of an unexpected system restart or driver crash.

As a noob with only a 240mm aio on my cpu. What should i look to buy other than an alphacool or ek waterblock.

Based on what ive been told its either an eisbear aio or a custom loop. However for a custom loop i wouldnt know what to buy, but i would be wanting a 360mm rad. Any suggestion on what i should get for my thermaltake p3?

whitestar85 · 26 Mar 2019 at 19:21

What sort of junction temp should I be aiming for on stock cooler atm

Got MV 1005 MV
1825 MHz core
1050 memory
Nothing too mad

60c in game junction 79-86 if I add any MV it soon motors up to the 100 area

I did try once at 2075 MHz 1100mv but junction was 108c but broke 30k firestrike hehe
