Mix i am testing at the moment

231-233GB/s (216GB/s Stock) +7.5%! WOW
1375 - 1500 - 1625 Mix
No EDC Errors Mem@2100Mhz (1000mv) / Core @1350Mhz
Tested with 3DMark ,Valley,BF1,FC Primal




Hi mate,

I have a question, did you try these timings with any memory intesive app (like some newer games)? I tried this timing, ok for membench, but any game I started I got insta-crash.

What voltage are you using for this timing? Your input would be highly appreciated. Thx! smile.gif

I've tested farcry primal, the witcher 3 , need for speed, project cars (ultra + ssaa),3dmark, battlefield 1, the forest,gtav, doom, watch dogs 2 ... Not a single crash
2100mhz is my max stable freq.

I can say that tw3 is reeeeally hard on the core, perfect to find the lowest voltage possible.
Battlefield 1 (Ultra + 125% Scaling) is really hard on the memory, 10min and you'll know if the memory is ok. Valley extreme hd is also good for fast memory tests

bios.zip 109k .zip file

thanks for that. I am running a G3258cpu with igpu so I am confident I can boot into Windows if anything goes wrong indeed but you are right, the red devil has a physical BIOS switch anyway so risk is very limited. will try certainly over the week-end and see how it goes.

Grazie m8!

Forgot to ask, does your card have Samsung memory? mine does, thats why I am asking. And do you currently use the before mentioned timing right now? Asking because the mem timings are the last unexplored section of my OC testing, would want to get that one out of the way also, but for some reason all timings I found on this topic don't really work for me, aka unstable, funny enough 1750 timings in the 2000 bracket work just fine.

Thanks again!

My Samsung memory does not go over 2050 even on stock timings and voltage.

So i decided and i am using the 1750 strap on the 2000mhz which is rock solid on 2050 mhz with no EDC ERRORS.
Tried Uber-Light Timings - rock stable on 2000mhz, but gives a plenty of EDC ERRORS on 2050 mhz, so i went back to mine 1750 strap on 2000mhz.

Today i am going to the shop to get the Accelero Mono Plus and probably later today i will post some output here about the results.

even if I said I am confident to recover from a bad BIOS flash modifying memory timing, reading you guys comments with memory clocks limits you are reaching, I am wondering if its worth the pain considering I can hit 2250Mhz with my card at stock voltage
guess its up to me but any further thoughts appreciated

Every single card has a different overclocking capabilities. My card is really limited on memory overclock as others aren`t and can reach 2300mhz.

The best way would be to find your individual card capabilities by testing it on different speeds. If your memory doesn`t like much overclocking, it would be worth to try and set more aggresive timings running on near to stock speeds.

I am more biased onto 24/7 stability and even a single EDC Memory ERROR is not sufficient for me as i am looking for a total stability.

Test it with very intensive memory apps such as - Unigine Heaven, on it`s maximum graphical settings, eg :

8x Antialiasing
Extreme Tesselation
Max Anisotropic


This is forcing the card memory and power draw to maximum, making EDC Memory Error detection much faster.

I am using Heaven to test both core and memory OCing capabilities dont worry.

as I said on this thread I have reached 1450Mhz core and 2250Mhz memory at decent, read not high, voltage. I am just looking at the last oomph the card can give me for the money I paid (which I am not complaining with of any sort BTW $$/fps is fine with me with my RX480)

Even if you're able to reach 2250MHz, uber timings at +2100MHz yields a bit more performance, and also it puts less stress to the memory controller and the core as vram frequency isn't that high.

Why? I have a card running 24/7 on memory intensive algorith with bilions of mem Error.. So I think single mem errors have absolutly no impact on GPU working...
