My custom timings for 470 8GB Nitro+ OC (11256-02-20G) - Samsung mem

For the powersaver guy :
(1126/2100 @ -120mV)

For normal usage guy :
(1300/2100 @ -100mV)

Congrats, you have a card that won the sillicon lottery...

You do realize that 98 out of 100 cards like that can't handle -100mV while running 1300 core??

Try this on a 6xGPU rig.. and while NOT using claymore.. if you can do that, i will say: Congratulations to you sir.

Why do you think that 1300 is much when the def clock is 1266 ?  

Also why not claymore ? Not enough power hungry? Better sgminer ? Why?

Also im running a 5xGPU rig with -120mV for weeks now on ETH (145mhs)...

Read your post.

1300 core with a down-volt of -100mV..  (which is very unlikely to last long (perhaps on a few cards..))

then you say: "for the power savings guy.." core 1126 <-- that's almost minus 200 core!! and you lower voltage by -20mV in comparison with the other one.... am i the only one who finds this disturbingly ridiculous?

I was talking to a friend of mine, who is one of the few out here who can also successfully add vddc/mvddc/vddci offsets in a rom, we will, just because windows seems to be the the new thing in the mining world...   , we will, as soon as we find a few spare minutes, we will setup a windows rig and play along.

This is normal for 470 NITRO+

I have 6x gpu rig same card all full stable 1300mhz/2125 -100mV for Zcash & XMR, for eth Use lower gpu clok 1150/2125 -175mV

i don't know why are you stuck with the voltage thing?
If you can't lower it by -100 then you simply won't do it, the hashrate stays same (or even better) if i don't undervolt.

The point is the ~ 850hs at 1260/2100 with samsung memory. Thats stock core/+100 mem, which doesn't add on the power consumption.
On full stock 1260/2000 i get around 815hs.

Will put this rom tomorrow on my 5x470 rig and run with sgminer if that's whats "the thing".

No no, do it on linux with sgminer

I want to see you do 800 + ..

There's a thread from a client of mine testing a 480 4G rom i did for him, i got 800ish on lniux.. he did 850 with ease on windows..

That's my point..

The undervolt point is fairly simple. Card A has an asic quality of X percent (a low one!), which means it has an X amount of leakage, which means it can easily be undervolted and will remain perfectly stable.
CardB has an asic quality of X percent (a high one 'yeah sounds weird..'), which means it has a different amount of leakage and will not easily undervolt.
If you happen to have a good batch, your cards will handle that. If not, you will have systems crashing non stop.

I had a very good batch of Nano's, i could easy do -125mV VDDC and -175!!mV MVDDC, on all of my 100 nano's, others with the same reference design nano's couldn't even handle -100mV MVDDC....

Again, that is my point....

I think sgminer is faster, maybe 900hs with same clock

[Eliovp]

I think sgminer is faster, maybe 900hs with same clock

Well, prove it, linux + sgminer..

If you can do 900 on linux, stable for longer than 12hrs, i will fly over and personally shake your hand on my knees, and you can take a picture of that..

Core clock 1250, memory clock 2075 , -69mV vddc.

850h Linux, sgminer

i'll run this on windows with clay clay, i will most probably hit the 900 marker and go over it if i raise that core even higher.

I would agree its not bad.



I flashed this on windows, strongly based off Heliox older work, just to see what barely breaking 800 on Linux gave me on Clayclay windows, since people like to shoot down my/his work because they almost get as much on Windows/Claymore than we do on Linux/sgminer-gm.

This is with undervolted vbios, i wonder what i would get if i overvolted the f out of it ? But this mod is very bad compared to 850 on Linux.

I think that mod above from Heliox would probably break 900 at fairly low core... It seem like you can get 10% more on windows vs linux, which should help all of you evaluate how good a mod is when you see sgminer/linux.

[doktor83]

No no, do it on linux with sgminer

So if you use macOS you would say do it on macOS...
Anyways all my rigs are on windows, all my friends rigs are on windows, everyone i know is mining on windows..
Sorry i won't install linux just to prove you that my modification can do 800+ on it lol.

Even if it can't it doesn't bother me because i am just into increasing hash = more earnings, doesn't matter if its on freebsd, ubuntu, windows lol

I have cards like yours and I use Linux - I can test your rom and make screenshots for the community

What is your vddc with -69mV offset?

I took a screenshot for you on windhows.




Here, clay clay on windhows. I probably didn't even use the right drivers
Bye bye 900 marker.

915h, core 1320, mem 2025




Got 908 with core 1266 and mem 2050 stable as well.

 


Edit: linux after 10hrs 850 rock solid.

Nice result Eliovp, if Windows+clay is better, why not use this combo? Funny that I get better results with win+sgminer combo (about 5-10h/s more than claymore).
Seeing that you guys achieved more, it's probably time for me to get back to the drawing board. I obtained my timings using claymore+win to test, maybe I should have used sgminer instead, seeing that it's faster, and also, maybe it liked some of my other test timings better.

I feel that r9 390 should obtain better scores though, has a ton of bandwidth, so I think that some really tight timings on a 1100-1200mhz mem clock (the 512bit bus will do the rest), should top off any RX card easily.

I dont get it, you said 1250/2075. On the screenshot i see vddc 0.950 which is amazing if the core is really 1250, but you cut it off from the shot. and the mem shows 2025, so is it really 0.950 on the 1250/2075 or these are diff settings on the shot?

Its 1320/2025. You can see that on the shot... look at GPU-z It's pretty nice core for -60~mV

I wasnt sure its from the same moment, because oen was screenshot the other one is camera photo. Anyway if it is 1320 on 0.950 is amaing.

If it's earlier than RAS, but it matters, it's probably PMG.

I think in preRX PMG is later than RAS, although it is earlier in RX. At least i am guessing it is PMG.
I am more interested about first and third 32bit words from the end of timing string.
First 32bit word from the end looks like set of four bytes with some Ts
(they are growing from strap to next strap in almost all cases).

It's PMG. Oh, first and third? That would be your ARB_DRAM_TIMING2 and your MISC_TIMING2, IIRC.

Anyone know what register[7] contains?

Code:

                  PMG      RAS      CAS      MISC                                             
77700000 00000000 22339D00 CE516A3D 90551112 30CB4409
