If you can muster 1200/1625 from the card using that BIOS, I am pretty sure you will get better scores.

What are your issues really?

I guess I lost my "nice score" reference from watching you and fyzzz. blushsmiley.gif

Anytime I used to apply an OC (using trixx or afterburner) I'd get a split second of weird artifacting.
That's gone now with the stilt's memory timings though.
I always thought 1130 ish was pretty low with +100mv but I guess the benchmark scores are good.

Right now I'm hitting 78c with a max voltage of ~1.328-1.35 on GPU-Z... (fan speed reaches ~50%)

thinking.gif Not sure I'd want to go to +200mv but maybe +150mv is doable?

It's nice to stay away from hitting the power limit actually.

What I do is to get the memory to max knowing where each of the straps ends.
Keeping the core at stock first.

1250
1375
1500
1625
1750

If you tend to artifact (it's actually a lock up and a bios dependent trait as well as a card's) in a value in between those straps, go back to the previous one set at max. (performance is better there) then move on to the core.

Also try setting the DPM7 value a bit higher than your VID.

Shoot for the perfect blend of core clock and Voltages to minimize heat.

Hi!

I have a strange problem - no one of provided BIOS'es working for my card (Black Screen and no POST).
Tried ELPIDA MOD and NO MOD, STOCK MOD and NO MOD - result is the same.
My card iz XFX 290X 4GB Reference with Elpida memory.
Flashing performed through BIOS (atiflash.exe).
Flashing back to stock working as before, so no problem with flash process.

Original bios from my card attached.
Stock_Backup290XHawaii.zip 128k .zip file

If someone know, what could be done with this to successfully flash 390X bios please let me know smile.gif
post #706 of 1872
Okay guys I just found something a bit strange.

A while ago I flashed the 390X bios and did a clean install of amd's latest beta drivers.
After playing around with that for a while I decided to go back to stock and just modify the memory timings. *I DID NOT REINSTALL DRIVERS*

At 1060 core and 1375 memory it gives me this score: http://www.3dmark.com/3dm/9254751? 12664.

Now here's the interesting part. After all my messing around I decided to wipe the amd drivers completely and do a clean install.
Look at the score I get with the same settings: http://www.3dmark.com/3dm/9255159? 12112.

So my score just went down 550 points JUST from doing a clean install of the new beta drivers, both tests were using THE SAME BIOS.
I literally ran the first test, wiped/reinstalled the drivers and ran the 2nd test right after. (ran it twice to confirm)


TLDR: I hypothesize that the amd drivers detect what card you have through your bios, and apply different settings depending if it is 290(x) vs 390(x). So to get a 500 boost in your firestrike score flash a 390(x) bios, install amd drivers, then flash the bios you want to use WITHOUT reinstalling amd drivers. I don't know how this affects stability though tongue.gif

Install HxD
Open your rom.
Hit ctrl-f and search "rgr"
Scroll up till you see the memory timings. Easy Peasy

Just installed HxD... looking at my ROM now. Holy shinzu... awesome!

You rock man. thumb.gif

How do you know where the memory timings start? Need a clue here.

Edit: NVM... think I found it. This is cool.

Sorry, didn't meant to send that yet. tongue.gif

Okay here it is.

First thing to do is to look for the stock BIOS and mod it via a HEX Editor. I use HxD Let's begin (Click to show)

Hit Alt + F to do a search query and type "rgr" this is very close to the memory timings section.

Scroll up till you see these: Marker, the timings should be above these (Click to show)
Warning: But before that, A little rundown. (Click to show)

Some roms can support two memory types, namely Elpida and Hynix. As shown above.

Now, if you look at the Memory timings section of the rom, you will see the pointers showing 01 and 02. If the card can only support one chip make, it shows 00.
In this rom, as shown by the image above, Hynix memory was listed first. So 01 stands for Hynix and 02 points into the Elpida thing.
Timings section. (Click to show)

It means that, if you have Hynix, you should only mess with the timings that points to Hynix. And Elpida and Samsung. Whatever!

The picture above also shows what @fyzzz and I were talking about DD-D1, 77 71, etc.
She's sooo tight, she said (Click to show)

Final Output.
This is yet to be proven but tightening the timings sometimes bring stability at higher clocks. It does it's magic on mine. So try your luck.
What I did was, copying the timings one step at a time. Say, 1000 for 1250, 1250 for 1375, 1375 for 1500, 1500 for 1625, 1625 for 1750, save the rom. Flash, test, go tighten her more.
If she scored better, I try some more til she won't get to run even 1500 after targeting 1625.

I think I ended up using the timings from 1250 for 1625.

If you spend time with caressing her, she will be tighter (Click to show)

Lastly,

Correcting the Checksum for the rom file. Checksum: WRONG. (Click to show)

Hi guys,

Great work here, and thanks to all who contributed to this awesome project.
Any advice on which 390x BIOS to use for my Asus r290 DCU II @ 1000Mhz core and 1260Mhz mem w Elpida memory.
The stock bios on the 1st page only has the reference core @ 947Mhz, and the modded BIOS is probably too high for my card.
Thanks!

hi, i have tried the 390x elpida mod on my asus 290 reference and its working great.. much more cooler, 95c to 65-70c due to more active fan profile and less coil whine.. thanks for the mod!
