Custom RAM Timings for GPU's with GDDR5 - DOWNLOAD LINKS - UPDATED

04 is +25mV and F0 is -100, EC is -125

I'm assuming you're replying to me? I'm just showing Heliox "Something else" (he might never have seen) although indeed never negative. Finding a vBios with 06 was when i changed my naming convention.

The difference between 04 and F0 is 125. So i used to (over half a year ago?) write "-125" for 04 -> F0 (such as NITRO's 8G) at the end of my vbios mods, like this;



It made sense to me and that's the way i presented it to tharp, a long time ago, because the undervoltage offset vs stock was -125mV, i.e. F0 in this case.

At some point, it started getting messy for a client, because he had some card at 03, 04 and 06. So i realized it didn't make sense to write it down that way anymore, stock voltage was completely irrelevant/not understood by my client anyways, so he didnt need that information.

Now i write -075 for F4, etc.

can anybody help me please, best strap for hynix 470?

Can you push hynix to 2100mhz?  I can only get 28.9 (hynix) vs 29.5 (samsung)

I'd say not without cooling for the RAM.

It really depends on the DPM voltage set. Some gpus have higher DPM state without global vddc offset, for example my last MSI Armor 4G 470 has 1.185V DPM7 voltage, while RX 480 Sapphire with global offset of 04 has default 1.0V+0.25V. Open wattool and it will tell you all

I have my hynix 30.4 at 2080, it does 30.5 on 2100.

GPU #0: Ellesmere, 4096 MB available, 36 compute units

Thats on windows though...

FWIW, for months I've been running MSI RX 470 Gaming 4G Hynix @ 2040, and MSI RX 470 Gaming 4G Samsung @ 2080

Didnt think I should squeeze them anymore.

And what core clock speed?   I see about +0.7Mh increasing core by 100mhz

So I assume you can break 31 @ core 1250 then?

1220/2150 = 31+ on linux


This is a screenshot of 1165/2150 on an old kernel 4.10 with old drivers, same settings on 4.11 and latest amdgpupro drivers gets me 31+ with these clocks.

It depends...sometimes raising core might not work as expected, besides I like my gpus cold and powersaving.
When this timing passes 72h barrier I will do additional tests.

Given the low values for 32AW, I had guessed that it was a multiple of FAW.  Just in case it wasn't I had been zeroing both in my first experiments with custom straps.  Today I did a test and found out 32AW does make a difference even when FAW=0.

Cool.  Still on 4.4.0 and 16.40 here. I may have to upgrade!

What strap has given you the best hash rate with the rx470?

depends what type of memory it has

My Samsung strap was posted before, but here it is again:
777000000000000022CC1C00CE615C45C0571016B30CD50900400700140514207A8900A00300000 010103139962C3617

With 2100 mclk I'm getting 29-29.1 with sgminer-gm 5.5.5, kernel 4.10.5 & AMDGPU 16.60.

What core clock?

That's with core not locked, and Powerplay seems to settle around 1200.  If I lock the core at 1167, I get the same speed.

What do you get with same core and 2150?

The memclock seems to have a hard limit of 2100 on the Sapphire ref-style 470.
