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

Just a little perl script I wrote to allow me to test changes easier.

Code:

There, in stead of bragging.. small basic change.

tFAW = 0  
Really, do I read this right??

Elpida... you can change some random things and it will still work...

In comparison with Samsung, Elpida runs on 3 cycles, which is interesting

Anyhow, tFAW 0, i'd suggest to try it, you'll see works fine.

How did you get timings in MISC register? From below I could deduce that first byte is trpwra and last bits in the last word (4-5) are trp. Now the only place where you can have trprda are bits 19:16, so you can fit trfc between bit 15 and 5 (which is probably 7 or 8 bits, I don't know as I don't have specs), but:
1. none of the values makes sense to me compared to 146 and 160 values
2. there's still a part left in bits 23:20 that changes between your straps - what is it?

Just a little perl script I wrote to allow me to test changes easier.

Thank you..

Dude you are awesome !! I have been waiting for this try for quite some time. I will let you know the results soon. If you want to describe whatever small change you did.. How would you do it? In other words What has changed in the strap by you? Thank you

Nice

Interesting to know that there are others out there (who seemingly popped out of no where) with some decent knowledge.

Kudo's!

Has anyone had an issue with modding the bios where after they flash a bios that works fine when a single card is plugged in and shows the correct settings but when 2 cards plugged in that same flashed bios shows the minimal settings like 680 core and 975 mem?

Yup, nailed it

You equalized TRCDR and TRCDRA and set TREDC at 2 cycles. Better indeed! Kudo's!

ATW consumption?
Voltage offset?
Results are great but at the end power consumption and heat is the biggest problem for the summer

ATW is Ugly , i didnt measure for the Dual cards since they are in my 24/7 Home PC , and that Elpida was just a random test before flashing complete rig.

However i have numbers for this

Triple MSI RX480 Gaming X 1180/2125 DCRI 16 - 72mv , pulling nasty 550W ATW from seasonic 1250W Gold PSU


I can lower the core while maintaining  same memory clock with higher offset to  lower ATW to 480W while losing 1MH

[laik2]

840W ATW 6x Sapphire Nitro+ RX 480
