AMD Memory Tweak - Read/Modify Timings on the fly!

Good to have HBM2 at 1050Mhz up to 1120MHz for Gaming at Lowest possible mV (Cool & Quiet means less tW)
+ Timing Tweak (You need to Load it every time You restart WinX)

 

Thanks for releasing the awesome tool!

Running vega 56 Pulse with Hynix @950Mhz core (3Dmark misread it as 960 because of registry setting)

Firestrike Left is tweaked timings right is default timings
Graphics Score + 4.1 %!

Is cl setting really working because results not changing when adjusting that value only?
Is there a way to apply values on boot I was trying a shortcut but couldnt get it working is there a help guide somewhere?

Default timings

Code:

<values cl="18" ras="24" rcdrd="23" rcdwr="12" rcab="37" rcpb="37" rpab="13" rppb="13" rrds="3" rrdl="3" rtp="6" faw="13" cwl="7" wtrs="5" wtrl="5" wr="14" rrefd="7" rdrddd="3" rdrdsd="2" rdrdsc="1" rdrdscl="3" wrwrdd="3" wrwrsd="2" wrwrsc="1" wrwrscl="3" wrrd="1" rdwr="17" ref="3200" mrd="4" mod="12" xs="216" xsmrs="216" pd="7" cksre="8" cksrx="8" rfcpb="96" stag="7" xp="7" cpded="2" cke="7" rddata="17" wrlat="5" rdlat="14" wrdata="1" ckestag="2" rfc="208" timing="0" zerorpm="True" tdplimit="50" maxtemp="85">

Tweaked timings

Code:

<values cl="14" ras="24" rcdrd="12" rcdwr="5" rcab="42" rcpb="42" rpab="14" rppb="14" rrds="2" rrdl="4" rtp="4" faw="14" cwl="6" wtrs="4" wtrl="9" wr="14" rrefd="8" rdrddd="3" rdrdsd="2" rdrdsc="1" rdrdscl="3" wrwrdd="3" wrwrsd="2" wrwrsc="1" wrwrscl="3" wrrd="1" rdwr="18" ref="25000" mrd="8" mod="15" xs="270" xsmrs="8" pd="8" cksre="10" cksrx="10" rfcpb="120" stag="7" xp="8" cpded="2" cke="8" rddata="17" wrlat="5" rdlat="14" wrdata="1" ckestag="2" rfc="208" timing="0" zerorpm="True" tdplimit="50" maxtemp="85">

 

Best is to Upload screen with Tweak (better readability)

 

Not stable for me
tFAW & RDDATA on -1 is artifact showcase
tRAS on 27, 26 creates bugs in AC:O (Today playing some of it w/New Tweaks to check)

 

RDDATA 17 was my stock value and is stable for me and a bit faster than 19. tRPAb and tRPPb stock was 13 but I get black square artifacts with other timings reduced so raised to 14 for the moment but these timings do have an impact so I might play around more.

Reducing tRas from 28 to 24 and tRFC from 244 to 208 gained me about 10 points in Superposition.

I am artifact free with these settings and no errors reported with OCCT GPU error check or game crashes yet.

Setting tCL to 12 seemed to make no difference in results.

 

So IMhO Vega64, 56 & Vega2 all have different HBM2 Timings.
What's good for 64 not always work for 56/VII etc.

 

Yes and even my friends Gigabyte V56 with Hynix memory has slightly different timings to my Sapphire V56 with Hynix. His tRFC was down at 168 or so.

Perhaps each batch of memory is given some defaults like an SPD that is then used for all cards using that batch. Or Perhaps each manufacturer is using their own settings. Without a larger data pool we won't know.

Edit - Also it seems good Hynix chips can have tight timings equal to Samsung chips at least at 950Mhz 1.25v.

 

Okay so I had a mishap yesterday and messed beyond recovery up my current win 10 install...so this morning I decided to grab a 1903 iso and install it. Plus I have magic drivers...been using the public for the last week...however using the same timings as my above 27k I now got this amazing score with full tessellation on.

 

Nice score! Whats your combined score like compared to previous windows? I am also using 1903 but with 19.4.3 and noticed my combined score seems higher than other people using similar hardware and wondering if it's Windows 1903 boost. Are you using AMD 26.20.11010.4?

Edit- Yes I see your picture on previous page you got 50% increase in combined score while only 8% extra for Graphics and 6% for physics.

 

@mtrai
As i said, 30k is for Us to take (30k on Vega64, if You say that to someone they will not believe it )
I will join the 30k Party in summer when i plug my ZEN2 into current build

But here we are....
@wannabeocer will be first to take it iMO or You

 

Prior to win 10 1903 it would hover around 6800 to 7100. That 50% is due to windows 1903 IMO...it just works better. Also keep in mind I am using a non-public driver aka vanguard. Yes the program is doing well...and is considered an essential part of driver development. When I post with these drivers I will only screenshot vs link to validation on 3dmark. Can't give away things. The screenshot of my previous 27k was edited to remove things.

 

Yes 30k is now in range of the average user. We are showing it. Yes I have access to drivers that are not public. However they will come. Note I am having to recreate all my testing since my mishap yesterday.

 

Nice tool guys!
Here are the timings I use ,I think they are pretty stable.

 

Υes the high combined score is due to 1903 build, I am with windows insider build and I score about 9k to 10k depends on the cpu clocks.

 

Are you sure that P3 state activates? For me, if i set P2 and P3 the same voltage, than P3 is not activated. It locks on P2. So i set 951mV for P3

 

Υes there is no problem. At what speed have you clocked your hbm?

 

Now i have it at 1070. but it doesn't matter at what speed i set it. If i set same voltage for P2 and P3 it locks at P2

 

Are you guys checking for memory errors becouse im sure most games will be unstable playing with such a tight timings.

 

May it's bios difference, mine is a sapphire reference. What's yours?
