Best Memory timings for X8x0 XT/PE -> HERE

[eshbach]

tested all working values (ie ones that didn't cause artifacts) at stock speeds. These are the best I have found, with them i gain over 5 full frames per second in nature at the same clocks vs. stock timings.

TRCDRD: 7
TRCDWR: 3
TRP: 5
TRAS: 13
TRRD: 4
TWR: 6
TR2W: CL+2
TW2R: 4
TR2R: USE TWR RULE
TR2R: 2
WR_LATENCY: 1.5
CAS_LATENCY: 7
CMD_LATENCY: 0
STR_LATENCY: WR LATENCY
REFRESH_RATE: 0x75
TRFC: 23

[G H Z]

Thanks for this eshbach:)

How do the best timing affect overall speeds? Did they lower your clocks at all?

[eshbach]

my max benchable memory clock is unaffected but i do start to get artifacts earlier.

[saaya]

stickied! :D
great work ehsbach! thx a lot for sharing :)
what are the best timings to reach the highest mem speed? maybe loose timings help to reach high enough speeds to make up for the worse latency again?

[k|ngp|n]

Good results....5 frames accounted for.

i will work on this next and post when i have the info.

[Evil_Spork]

tested on my x850xt.

i noticed a very good boost in low detail tests in 01, and a few in high detail. 10fps in nature.

a+ settings! :)

[gocchin]

The settings gave me a big boost in nature and a bit in drag but I had to clock the memory down from 668 to 650 to be artifact free...

[Moonman]

Wow!
How long did it take to figure this out?

My nature vent from 258.8 to 265 on stock frequencies.

Looks like a nice job , well done :)

actually 264.5 before timings and 269.6 after timings w/ stock 2ghz cpu and 200mhz ram.

Yes, it starts to artifact earlier, but if you wanted to you might still be able to bench at 668 without it crashing.

[Kinc]

Gave me a boost from 661 to 678 in drago low and 276 to 286 in nature (580/600MHz stock cooling and voltage, FX-55@3200MHz). These timings sky rocketed the temp of the memory and gave me artifacts as early as 605MHz. So I did a quick setup of active cooling and managed to match the default timings in max-oc.

Good job there eshbach!

[sinsinking]

hm.that's a nice result for tweakering.
What heatsink is good for oc and low temp for X800XL?
ATI silencer 5? zalman any good, not the 80D-HD one.

[fatty]

Hmmm what program are you using to adjust the cards mem as ati tool 0023 or whatever the mem settings bit is corrupt??? this is with an x850xtpe

for X850 you'll need the .24 version.

[Xassius]

I'm getting corruption (straight after applying settings) on my Asus X800XT.

And some of the "optimal" settings listed here seem to be increasing the latency (e.g. for some..value (original) 6 to (supposedly optimal)7)

Does the Asus X800Xt have a different BIOS?

Does you X800XT have 1.6ns or 2.0ns RAM?

i think since XT RAM is rated at 500mhz it may have difficulty doing these timings.

and based on my bios, only one timings goes up and it does actually boost performance setting it higher rather than lower.

[LikwidKool]

wow I wish I had an x850 to test this out! Hopefully soon!;)

[ZeroHero]

great tweaking. Is there any tool to tweaks geforce timings ?

[Slimmie]

I'm curently running my x850xt pe @ stock settings. Will the stock cooler allow me to run those memory settings without artifacts? Or do I need some better cooling?


Edit: I have tried the memory settings and they are kickass!

Testrig:

AMD Athlon 64 3500+ Newcastle (stock)
DFI NF4 Ultra-D
G.Skill PC4400Le @ 200mhz 2-2-2-7
Sapphire X850XT Pe 540/590

Before the memory tweaks:

3dmark 2001se: 260**
3dmark 2003: 132**
3dmark 2005: 6332

After the memory tweaks:

3dmark 2001se: 262**
3dmark 2003: 134**
3dmark 2005: 6417

Nice tweaks, but when I scanned for artifacts with Atitool I had artifact @ stock settings, so extra cooling is a must have.

[MaxxxRacer]

I tried the tweaks on 3d05 and only gained about 45 points... within the margin of error. but atleast you guys are getting good results

btw is there anyway to make it so that ur computer boots with these settings?

3d01 result?
which card exactly and what bios?

are you sure the timings applied correctly?

[M.Beier]

Great performance leap !

But... Damn its hard on the card..
Tested at my "std" settings, the one I use normally... Reached 29960 marks i 01SE, and 288xx before, quiet a leap... But I wanted to test at my "bench" setup, couldnt even apply,... It seems my mem has to go 20 mhz down than topspeed, and then it doesnt pay :( - Got 200 marks less than without the tweaking - but hey - Just my card, great job mate :)

glad to help you push past the 8k mark, great score.


@saaya: So far it seems to varry from card to card. I get the same maximum clock speed, but without more cooling it does artifact a little more.

[saaya]

with more cooling it artifacts a little more? then remove the extra cooling! :lol: j/k :D

you mean with the tweaked timings it artifacts a little more?

[eshbach]

with more cooling it artifacts a little more? then remove the extra cooling! :lol: j/k :D

you mean with the tweaked timings it artifacts a little more?

for me (and a few others it seems) running the tweaked timings causes more artifacts when running at max OC unless extra cooling is added to the ram. i get no artifacts at stock speed with these timings.

hope that clears it up.

[Viss]

Tried the timings.

Almost +600 in 3D01 :)

[[XC] moddolicous]

Wow, I'm gonna try to figure out these onmy only ati card (9200). Does anyone here know if I can do these on an NVidia cards?

[TekXoID]

This killed my FarCry stutters! Great work man...:D

[Mini]

So logically when you turn down the timings you lose max mhz... Just like with ram in PC? Hehe...

The question then is if it gives more performance with low timings low mhz or high timings high mhz...

Im not gonna meddle with my timings if my max mhz drops... I think you can max gain .% performance and its just not worth it :P But thats just me...

[JohnyKnoxville]

worked great for me

[uclajd]

Caused mine to lock up and artifact. I'll have to try with individual settings one at a time.

And how many volts do you use on your gpu?

Does anyone have the full list of the stock timings?

it actually varies a bit between bios/manufacturers.

great job eshbach! bumped up my score by ~350 points in 3dmark03.

[Rauf]

did a little test changning just TRP and the rest stock timings yesterday:
card is a X800Pro Vivo@XT PE (AGP), no v-mods

maxclock TRP 5 is 625MHz:
Drago low: 445.0
Drago high: 222.9
Nature: 249.9

625MHz with TRP 6:
Drago low: 445.0
Drago high: 222.3
Nature: 247.7

and now for the interesting...maxclock TRP 6:

660MHz:
Drago low: 446.6
Drago high: 223.3
Nature: 256.3

car high and low actually managed 670MHz :)

haven't tried with the timings you posted though. so don't know how that would work with TRP 6...

[mike]

Thanks for the timings - awesome! Got 90 more points in 3Dmark05 at stock settings.

I didn't back up my original settings - assuming the reset button would bring everything back to stock - anyone can give me the stock timings for an ATI x850 xt pe pci-e ( ATI version)

Thanks

And 300 vs 295 in high dragon.
Can other people please test this if this is true, because i think there are best memtimings for each game test in 01se.

I was hoping that those timings would work for me too, but sadly they don't; eshbach's still give best FPS, both in Nature and Drag's. The timings that you posted are actually almost identical to my stock timings -- only refresh_rate is changed.
Just thought I'd chime in and let you guys know.

Props to eshbach though, never thanked you, but those timings give me ~7fps in Nature and a boost in the Drag's too :cool:

[Rob94hawk]

why should I dl Ati tools? is it better?

This is what I would like to know. Everytime I try to scan for artifacts with ATITool (.23) and stock settings I still get artifacts yet I play games with no issues @ 1600x1200 (Doom3, Dawn of War)
:confused:

[Sucka]

This timings helped me break 97K in AM3 with a stock cooled card, thanks a lot. I didn't even test them on other benches yet, i imagine i'll see the same results.

Even boosted my x800XL, nice work.

[DarkManX_BG]

Help guys, I just tried these timings, got a performance drop and now when I use my stock timings (which I had written down), I get almost 100FPS less in Drago Low. The other tests are fine.
My guess is that I've confosed some of the timings, can someone post the stock timings for a Club3D X800XL please? Thanks...

[DarkManX_BG]

Nevermind, solved it. These timings dropped my Drag Low by 2FPS but gave Drag High and Nature a healthy 3 respectively 6.7FPS boosts. Definatly a keeper :D


(it was artifact city at my 24/7 overclock though, so I'll only use them for benching...)

[busta`]

Could anyone please give me the default settings for an X850 XT? I accidentally overwrote them and I want to make sure that I have them to fall back on.

They dont work with ati tray tools, they dont have same values.
So ati tool is the only if you want it correct.
This is the value that make mem artifact faster:
TRCDWR: 3 instead of 4

Correct values if you use ATI tray tools:

Well, this is the second straight card that just doesn't like eshbach's enhanced timings. This time my new x800xt-pe when set to these timings will artifact even at stock speeds lol. I guess I am destined to bench on the stock mem timings for my video cards lol.

[deltarealm]

I have messed with the settings alot. I determinded with my card particular card there was no articfacts, yet if let looping something like 3Dmark or ATi tool for any length of time, if would lock the card up at some stage sooner or later.

Just for people's info:

I'm using a Sapphire X850XT (not PE) and eshbach's timings gained me 180 points in 3DMark '05 when the card is at stock.

LOL @ the score!

I only had to drop somewhere between 6 - 20 Mhz off the memory clock, but using your timings gave me the extra 200 points I needed to get 8k!

Have a beer! :toast:

EDIT - I'd be intrigued to know what people's experience would be of using different refresh times. I calculated the best refresh for me to be 0x23, but didn't bother to test more. 0x75, as suggested by eshbach, sounds too slow to me.
I suspect refresh would be more of a stability setting than a performance setting. Those of you on DFI boards - think about the Tref setting in the BIOS...

not shure if it has been posted but the 7800gtx uses the same 1.6ns ram that the x850 uses if someone knows what timings it uses then in theory you could make a custom x850 bios that would be able to overclock to almost 1400 ram! does anyone know what these timings are?

I`m check "Memory refresh rate", ATT bench.
Default is 35 - 7250

Thats a wicked idea, would wish somehow it could be possible without some sort of advanced coding/hacking of the bios to make it trick out. Maybe its a hardware limitation would make such a thing impossible.
Personally I have virtually tryed every timings setting possible with the X800 and no luck getting any better (well not at least 100% stable).

Good thing is the X800 and X850 still stack up well to ATI's lastest offering and is still DX9 based, so no need to feel as being far technologically behind in the hardware (for those of use that cannot afford the lastest and greatest immediately as something new is released).

[RipperFk]

So, I`m trying...
Reference X850XTPE
Stock vs Modify
7250 vs 7400
+2% perfomance. No bad :).

TWR ->6
TW2R ->0
TR2R ->1
Memory Refresh Rate ->255
TRFC ->16

I disagree.

Many posts in this thread show lower timings outweigh the slightly reduced overclock, meaning latency is the limiting factor.

My results (see previous posts in this thread) show approx. 15 Mhz reduction in clock speed as a result of the tighter timings, but the tighter timings equate to 50 Mhz clock speed increase!

How should I set them?

[theonlybabyface]

I'd like to know that too??? :confused:

My guide is for changing the timings with ATI tool, not for bios. I haven't tested timings with any bios editors.

[X850xt]

can anybody help me... i nvr overclock my cpu and my x850xt but my idle temp is around 54degree and full load is at 91 degree. previously i did change the memory setting but howeer i had already format my pc, the ram setting still stay inside my bios?

[sean478]

how did you edit them? :)

[X850xt]

how did you edit them? :)
under the memory setting in ati tool lor... just use the drop down box and adjust it.

[sean478]

that way i believe can be saved to be aplied every time windows starts but other than that it's not perminant :) it doesn't change your bios it just overrides it :) :)

7485 ----> 7639 05 with what esbach posted. 154 mark increase at 650 mhz mem. there were some tiny kind of 1 pixel wide artifacts at rare intervals but hey :D. n1 man!

On my X800GTO2@16p, 580/600, I only get 6300 on 3DMark05. With the memory timings, I get 7100. How do u make those timings the default? ATITool always goes back to the default timings everytime I restart.

save to default, and run atitool with a schedule task wen u logon

or use a bios editor such as rabit

[shimq1]

Everytime I save it to default and restart ATITool, it gets grayed out, like I never saved to it.

[KoHaN69]

You can use RaBit to make a custom bios

But apparently you can do it in ATT (Ati Tray Tools) which I do not know how.

[KoHaN69]

Alright!

I talked to Ray, the creator of ATI tools, he helped me out.

IN Ati tools (att) Go to Hardware->Overclocking->Timings

IF thats not there,

Edit atitray.ini (default directory C:\Program Files\Radeon Omega Drivers\v2.6.87\ATI Tray Tools)

change hide_timings=1
to hide_timings=0


And YES, you could load them in profile, just be verrry careful, make sure they're stable.

I also recommend using "auto 3d detection", and make 2 profiles, one overclocked and one with default settings. When you play a game (or a 3d application) it will launch your overclocked profile, when you go back to windows, it goes back to default. That way there's MUCH less wear and tear on your poor x800 ;)

I just tried that, but everytime I set a setting, my computer would crash. If I did the same thing in ATITool, it wouldn't crash.

Some of the wording is different in Tray tools,

for all of us not technically savvy, here's how you do it

open ATI TOOL, no, not tray tools, ATI TOOL, click [mem], put these settings:


TRCDRD: 7
TRCDWR: 3
TRP: 5
TRAS: 13
TRRD: 4
TWR: 6
TR2W: CL+2
TW2R: 4
TR2R: USE TWR RULE
TR2R: 2
WR_LATENCY: 1.5
CAS_LATENCY: 7
CMD_LATENCY: 0
STR_LATENCY: WR LATENCY
REFRESH_RATE: 0x75
TRFC: 23

[APPLY]

Keep ATItool open, and open up ATT(ati tray tools),
Go to Hardware->Overclocking->Timings tab (if you don't see it, see my post above)

within the timings tab, there will be 3 tabs "Timings 1" "Timings 2" "Timings 3"

Within each of them, click [Read], and it will read the timings that you set in ATItool!

After "Reading", check "include in profile" and save them all to the same profile

Just don't be stupid, and play it safe!

Hope that helps! ;)

I used ATITool 0.24 instead of 0.25 Beta 10 and it loads the timings everytime now. :)

[deltarealm]

RaBiT v1.7 does not list all the timings and in the correct order, (e.g. REFRESH_RATE: 0x75 is missing from the bios editor).
Would of been good to make a custom bios based totally on all the settings, so as not to have to load/use ATi Tool each time windows loads.

[deltarealm]

read my post

I have read all posts and yours says nothing but use an editor or use ATi Tool (which I would perfer not to).
I saying RaBit does not have all the options and if it does, it is difficult to navigate to input the exact data to match the drop down menu.
Easy said than done for most people if you inclined that way.

Are these timing working with X800GTO2 that unlocked to X850XT PE too ??

[shimq1]

Yah, I'm using those timings on a X800GTO2.

[[cTx]Philosophy]

will try on x800xt AIW as soon as i get back my mobo...

[X3non]

Do you think these timings will be good on my X800GT ?

I have some timings much more tight than these. Have you tried to push it a little bit more ? :rolleyes:

[g0dM@n]

This will come in useful for me... gonna test it right now. :)

16 or 20ns?

[fscussel]

tell me something, can I safely use these timmings with the memory overclocked? cause here is my tought: when you overclock your ram, and then lower the timmings, sometimes it simple get stuck and wont work again until you reset your bios. If the same applies to the VGA memory, then if you get stuck after lowering a timming, you are dammed, because how will you reset the bios?

[shimq1]

If you use ATITool, the timings will only be applied when you want it to, it doesn't save to the BIOS.
