Wrong thread.

Also, they are working on it already.

Also, i will be putting up for sale an Elpida strap for Cryptonight.

1070h/s on a RX 580 at 1380/1950.
Maybe a bit more of tweaking and testing before that.

 Messrs. here all such clever and advanced, could you tell me please MICRON 8GB there are two timing one stable on frequency 2270 and gives 32.6 mh/s(777000000000000022AA1C0073626C41B0551016BA0D260B0060060004061420EA8940AA0300000 01914292EB22E3B16) . And the second at the same frequency gives 33.4 mh/s but slip errors (77700000000022CC1C00CE615C45C0571016B30CD50900700140514207A8900300000 0151031399D2C3617).)
 Tell me what can I improve to get the Golden middle. Interested in concrete clauses affecting radically on the speed and the accuracy of calculations.

Very Interesting ...

We will have a look soon.

Thanks!

Hi,

I tried to use the timings you posted on my Nitro 380x 4GB Elpida but it crashes in windows. If you have some time to spare maybe you could help me figure out what could be the cause and which timings to try to loosen to see if that helps?
You can also find my original 1500 timings below. I'm using this card to mine cryptonight.

Many thanks for your time!

Try mining with a small dag (i.e. Ubiq, Expanse).  Part of the issue is the memory controller isn't as efficient as GCN3 and later, but most of the issue is the large DAG size combined with 4K pages causing TLB misses.
I haven't tried it, but the 2M page support should work with Linux kernel 4.15, which would make a big difference mining ETH.

Inneresting... so this is a hardware flashed modded BIOS at stock clocks?

I'll throw what I have in here for search results if it can be helpful to anyone.
Pretty stable, been watching for 30 mins.

Why just not masq the rom as mining and get nvidia sign it for us

P.S: Just a gentle push to p106-100 micron, not much to gain of it but still worth it. ( GPU9 modded only )

Now a bit more for samsungs p106-100.

A lot of people have a raspberry laying around, a pomona clip is 25 cents....

Yes, my data structures are the biggest. It's definitely worth showing off those nasty, unsanitized fields and those dirty, dirty timing blobs.

Not sure why you guys are using flashrom instead of just buying a little SPI programmer...I suppose flashrom is a cleaner interface, but the SPI is more portable/versatile, and cheaper (Rasperry Pi's are around 25 USD, right?).

Haha, we can all start showing off shit too, "look who has the biggest one".

Is it worth it?

Nah..

I use to post screenshots to show how big mine was too though.. Realized quickly that i didn't need all the attention and that it was a waste of time



Btw, the better ones (screenshots), are those of the showoffs begging for info in PM's.. those are the good ones, and boy do i have plenty of those  


Oh! Flashrom tool works just fine (threw it on my github with P106 rom a seriously long time ago), a raspberry pie and a pomona clip is all you need....

Cheerio! Have fun getting your GTX 1080 TI up to 64Mh (edit: and higher..)  

Oh god, don't give the team ideas...

...oh god, I -do- kind of like it. That's even worse.

You'd definitely like Amiga, at least visual style (cca 1988)

Interesting.

Was that supposed to scare me, frighten me or excite me?
I already did modify GTX bios its pretty plug and play soltution, just can't find time to unbox my old SPI flashing tools and start playing around.

We even have AMD PBE clone! Note: Vega is not supported.

Lol!



It gets shittier.

Wattman? Its not THAT bad

Edit: nm, I see it now...I'm GUI person since I saw first Amiga

However, I'm also ATI person, only had 1 nvidia last 20+ years

Do you like shitty UI's, boys and girls?



EDIT: Pasted the unshitty-but-still-shitty version.

Go modify a GTX VBIOS, then flash it.

And I mean actually modify the values. Not cross-flash another model.
