I tried the setting ss-silver posted and works great for me on my Vega 56’s, only one I have some minor hashrate. Thanks for the great post and information!

What are the best brands for reference vega 56 cards?
Powercolor? Sapphire? Xfx?
I’m talking about mh/w efficiency. Or reference vegas 56 that can reach 200mhs.
I have several options where i live but first i want an opinion.
I dont guarantee this and if someone know differnt please correct me but according to Techpowerup’s bios pages Sapphire and MSI reference(not the AirBoost) 56 cards can only have Samsung memory so those are my favorites. Or if you buy reference 64s, all 64s only have Samsung memory.
other brands you can check the bios in techpower up and see if they come in hynix or only samsung
Some people like the hynix since they can be more efficient but its less hash so if you are thinking of targeting 190-200 I would try to get samsung memory, because looking at one doing 185 will bug you 
Also Im curious if anyone out there with a hynix has tried lowering RC to 34 and what results were. With the samsungs dropping RC from 37 to 36 gave +3Mh, and the TRM guide for ETH suggest this strap for the Hynix…
amdmemtweak --cl 18 --ras 23 --rcdrd 23 --rcdwr 11 --rc 34 --rp 13
–rrds 3 --rrdl 4 --rtp 6 --faw 12 --cwl 7 --wtrs 4 --wtrl 4
–wr 11 --rfc 164 --REF 17000
Looks like it would out preform the other strap with RC 36

What cards are better, vegas 64 flashed with 56 bios or vegas 56 with samsung memory. Or are they the same?
Vegas 64 are slightly more expensive here.
About the same really, depends on the actual card I have some reference 64s that are better and some that are worse than my reference 56 Samsungs. Cant go wrong either way reference Samsung Vegas will all be pretty good on ERG, even the ones I have with issues can do over 190, just takes more watts then I would like.
Can someone possibly give me some guidance, i have a vega rig and trying out the ergo. my 56 with hynix mem just cant get that sweet spot…
im running below straps
amdmemtweak --CL 20 --RC 36 --RP 11 --WR 14 --CWL 8 --FAW 12 --RAS 22 --REF 65535 --RFC 239 --RTP 5 --RRDL 6 --RRDS 3 --WTRL 9 --WTRS 4 --RCDRD 13 --RCDWR 12
1340 core / 850 vdd / 845 mem Soc 860
just keeps going dead. ive tried a few of the strap in the thread but nothing seems to work.
Try decreasing core to 1300, my vegas can’t do much over 1300 with 850 vdd.
If that fails, try increasing RCDRD.
It’s wierd for me about Samsung vs Hynix. In my case the Hynix are more efficient at running about 180 MHs, while the Samsung require more juice to get there.
For example my preset for ‘efficient’ is core 1300, vdd 850, mem 847, soc 850. My Hynix cards can get 180 MHs with these settings easily.
But my Samsung cards do 170 MHs with these same settings, and need 1350 core and 875 vdd to get close to 180 MHs.
The Gigabyte is just an anomaly and requires it’s own straps.
I tried your Hynix straps with RC 34 and it did give a slight boost. Will wait to see how long before any invalids:
amdmemtweak --CL 20 --RC 34 --RP 11 --WR 14 --CWL 8 --FAW 12 --RAS 22 --REF 65535 --RFC 239 --RTP 5 --RRDL 6 --RRDS 3 --WTRL 9 --WTRS 4 --RCDRD 13 --RCDWR 12
In terms of the TRM straps they are much lower because RCDRD is so high. They state this as the main factor for improving hashrate.
amdmemtweak --CL 18 --RC 34 --RP 13 --WR 11 --CWL 7 --FAW 12 --RAS 23 --REF 17000 --RFC 164 --RTP 6 --RRDL 4 --RRDS 3 --WTRL 4 --WTRS 4 --RCDRD 23 --RCDWR 11

i tried these straps
amdmemtweak --CL 20 --RC 36 --RP 13 --WR 13 --CWL 7 --FAW 12 --RAS 23 --REF 65535 --RFC 248 --RTP 6 --RRDL 5 --RRDS 3 --WTRL 9 --WTRS 4 --RCDRD 20 --RCDWR 11
seems to be working for now, with 1300/850/847 but im only getting 150-160mhs
the lower power settings is quite nice .
Try this standard Hynix strap from @ss-silver :
amdmemtweak --CL 20 --RC 36 --RP 11 --WR 14 --CWL 8 --FAW 12 --RAS 22 --REF 65535 --RFC 239 --RTP 5 --RRDL 6 --RRDS 3 --WTRL 9 --WTRS 4 --RCDRD 13 --RCDWR 12
Check in the miner and confirm your MemMhz is actually at 847.
Also, what brand is your Vega? I have 1 Gigabyte and it performs differently to the others.
will give that a crack , its a msi airboost oc. blower type these would be reference type cards i believe ?
checked the miner. its 1300/960 for socmhz and 847mem… but those straps dont work wither. crashes.
could it be the bios on it ? the bios label is just xxxxxxxxx in hive…
I haven’t got an MSI Airboost so I don’t know if they have peculiarities. But these are my suggestions:
Firstly, set SoC Frequency to something like 860, this should set an effective SocMhz of 850 which will reduce power usage.
Now the harder part is figuring out the crashes. It might be time to start from the basics. Remove the straps and see how long you can run at 1300 core and 850 vdd. If it still crashes then increase vdd to 875. Basically you want to find what vdd it takes to get the core stable, without putting much stress on the memory.
Once you have a stable core/vdd combo, then add the straps back in. If you crash, the main culprit should be RCDRD - increase this gradually until you are stable.
do i leave memory clock blank for the time being ?
You can set memory to 847. This way your settings will be:
core 1300, vdd 850, memory 847, soc 860 (850 real).
I set my blower cards to 65% fans but I don’t know if this is too loud for you.
And remove the straps.

well so far looks like
amdmemtweak --CL 20 --RC 36 --RP 11 --WR 14 --CWL 8 --FAW 12 --RAS 22 --REF 65535 --RFC 239 --RTP 5 --RRDL 6 --RRDS 3 --WTRL 9 --WTRS 4 --RCDRD 19 --RCDWR 12
is holding.
1300/850/847 … doing around the 173-175mh im guessing this is the best i will get out of it… which one would i tweak up to get some more out of it ? the core or mem ?
That’s good work.
First thing to do is remove the SoC Frequency setting, to give yourself more headroom.
Then you can increase the core clock until you crash, then up the vdd and repeat. You can increase vdd until according to your comfort levels for power usage and temps.
Take note that the power usage in software is usually underreported by about 32%, so if HiveOS reports power usage of 140W then your actual usage would be 185W. But for some models, like Gigabyte, it reports the actual power usage. eg. 850 vdd showing as 170-180W would be the true power usage, but if it shows 130-140W it’s underreported.
When you hit your limit for power/temps you can start increasing mem clock, start from 900. Generally Hynix ram will start to fail around 960.

could you share Gigabyte Hynix straps?
Finnally… Get my nitro+ vega 64 with bios 56 working perfect…
5 Days and always working around 198MH/s
Update…
Same straps…
And now with a Pulse 56… 204Mh/s
First Vega 56 Pulse… Going to see if runs ok…
