X1900 Series Overclocking and Feedback thread

[Super XP]

Ok, i'll try to make my explications more clear. Sorry for my bad english.

When you use atitool and when you disable the "ati hotkey" service, there IS NO MORE 2D or 3D mode.
So, when you OC, your card is ALWAYS at the freq. and voltage you assign to it.
Maybe your friend who fried his x1800 use for a too long time high voltages.

The trick is to create two profiles in ATI Tool.

First, save a profile called "2D-mod" (for example), with the 2D mod's setting for your card : 500MHz / 1.175v for the GPU and 600 / 2.1v for the memory (in my case, 1.955v . The memory on my card can run @ 750MHz @ 1.955v, need only 2.1v above)
Save also the voltage to this profile !!

Second point : Push the voltage, then, OC you card to your desired freq.
Save the profile under the name you want (example : 3D-mod)
Save also the voltages in this profile.

Now, in the "3D detection" panel of ATITOOL, check the "3D detection enable", and then add your 2d and 3D profiles, as in the picture below :


When a program that need 3D (like a game) is launch, Atitool swap the profile to the "3D mode", and OC your card. When you close the game, 2D mode is load.

Now, you have a 2D and a 3D mode for your card, but with an OC 3D mode now

-------------------

Thank you very much. I now understand 100% - do you know the stock voltage which the ATI Overdrie uses? like for 3D profile? for X1900XT & XTX ?

I think that should give me a general idea on stable volts at the 3D speeds.

Thank You,

In 2D mode, the GPU voltage is 1.175v - Vmeme is 2.1
In 3D mode, the GPU voltage is 1.45v - vmeme still 2.1

You have to test yourself the stable voltage for YOUR card.
On mine, GPU is stable @ 700MHz / 1.4v - and @ 732 @ 1.52v
Mem stable @ 800MHz @ 1.95v and at 864 @ 2.1v.

A friend of mine card need 1.55 @ 700MHz (GPU) and 2.3 @ 800MHz for the mem.

It is still overclocking, so results can be different for each card - and linked to the cooling too.

I cool the voltage heatsink with a lowspeed turbine blowing on it. Cooling it can help, i guess.

is that only the second slider when dealing with MEM or is it the 2nd and 3rd slider?

Good point.

One thing I know is that you "MUST" keep the MVDDC & MVDDQ @ the same voltage no matter what. Then you will OC successfully

Now i ask, how does VDDCI affect anything if we OC it?

his 1900 xtx (5.13 ) default system non overclocked t2 memory 1:2 ratio
4800 (clock 2400) dfi expert board
2g ram ddr400 (500+)

i got a his ati 1900xtx 512mb video card
4800 (2gram) dfi expert board.

all default settings (tested fully-memory) etc.

dfi chipset can get to 70dc (55-60 idel)



after the system is on for 1/2 hour

ide; temp (via ati) 69d celc for the video card

it can get to 112 (ati) ant ati tools b13 (via mbm 118) playing bf2

using 6.2 drivers

from time to time the system crashes (after a while playing) - monitor showing
(searching for dvi)
etc


did my card shut down (on restart it works)

is it something else.

iv removed mbm + ati tools, and reinstalled 6.2

tryed (non unlocking) and unlocking but (i do not overclock card)

------------

whats the problem ? it does not allways crash- but does it allot.

To me it sounds like you're having a heating problem. What's the temps in your room? How is the air circulation in your system? I have a DFI NF4-D as well, but my Chipset temps doesn't go anywhere beyond 43c dude, you are overheating and that's why your monitor goes out of sync (black screens).

Azhago,
y0 thank you so much for the reply and the great information. I was starting to get pissed off since i've used ATI TOOL .24 on my GTO and never had problems, but i figured since it's a new GFX CARD "X1900" and a beta ATI TOOL then probably would be buggy as well. Then i thought, "Why are some people not having problems like me with the B13" So i guess i'll give it another shot with ATI TOOL B13 when i get home tonight after work. I'll disable the services from the 2d/3d process from the CCC and see what happens when i use ATI TOOL B13. If i have any more problems i'll let you guys know, thanks.

Note:BTW the artifact scanner doesn't work with the X1900 and B13 right? Azhago, how did you noticed that you were stable at those speeds and votages...played games?

Must be your particular card because that is definately not typical. Run Vddq stock or just slightly higher and lean on the Vdd but only if you have good ramsinks.

VDDCI is a mystery. It might/could be the cores I/O buffer or the memory controller voltage but it any case it is already running fairly hot at 1.4+ and I have not played with it at all to get good ATItool OC's.

MVDDC. Leave MVVDQ a stock initially and see what the memory will OC to on Vdd increase alone before bumping the memory I/O buffer (MVVDQ) voltage. Use good ramsinks with increased memory voltages too.

Yes, artifact scanning doesn't work with x1xxx. Maybe in the future.

For testing the stability :
3DMARK 03 and 05 each 10MHz
3DMARK 03 make more artifact or hang faster than '05.

And after, yes, games

 

[Dynamic]

That's got to be strange really! I know what you're talking about because if you really want to stress a system out (CPU/RAM/GFX CARD) then instead of running a kiddy game run something that supports HDR/SOFTSHADOWING then you'll notice if your system is stable or not because it tends to drain more power and heat out of that compared to a game that is from 03/04.

I.E. run COD2 instead of COD1, you get the picture...and don't cheat yourself by switching the DirectX from 9 to 7, run it at 9, hehehe.

 

[Dynamic]

That's probably the reason why my monitor either goes out of sync or my system restarts when i move the levels for CORE/MEMORY from 625/725 to 700/800 in ATI TOOL B13 because i'm not giving it any higher voltages then the stock voltages it's set at don't you think? So don't think just because if someone has their X1900XT/XTX at a particular voltage overclocked that you will have the same results with those voltages on your card. Can't wait to get home tonight and fry i mean overclock my card, LOL!

Friendly advice, make sure you have good ventilation for your PSU and video card. Put another fan on the other side if you have to. Make sure you remove the dust from inside with a can of air.

Get as much efficiency from your PSU as you can.

 

[EastCoasthandle]

This is not making sense. What other services must you disable when ATI Tool reports that it has disabled them for you? How do you go about disabling them? What are you disabling (I need the exact file names) that ATI Tool did not disable? I do have ATI OverDrive enabled but I don't know what you are talking about. If ATI Tool doesn't disables these services what more am I to do??

ATItool doesn't disable any services. It will close running instances of Ati2evxx.exe in the current Windows session whch disables the 2D/3D splits clocks and Vcore on XT or better cards. If you disable the ATI Hot Key Poller Service that permanently disables the2D/3D splits clocks and Vcore, CCC overclocking and the PC shutdown cold bug in one whack.

...3DMARK 03 make more artifact or hang faster than '05.

I have found the nature test in 03 to be the most easily artied. Crank up the res/AA/AS and let the tearing begin!

I haven't seen it art. but it does creep down from time to time.

why isn't this a stick yet??

ATI TOOL problems with X1900XT

Can anybody explain this?

It get's this way I only use the scan feature, and the card is not even OC'ed ??

Thanks,

If that is a pure stock card and drivers the card is probably bad.

Viper

 

[Super XP]

Well, it only does that when I want to scan with ATI Tool. Someone from another thread told me that the new ATI CCC 6.3's should fix that problem ??

I don't know about that. Well, I do have warrenty so I will see.


Thanks.

Try to keep your mosfets and vregs cool. Here let me show you.

ummm i'd try to mount that fan better lol.

 

[oarsome]

Okay so I've got an ATI x1900xt, bios flashed to x1900xtx

I've overclocked with ati tool 0.25 beta 14

I'm managed to reach

747/864 artifact free
my voltages are:
VGPU 1.575
MVDDC 2.157
MVDDQ 2.157
VDDCI 1.575

Temps idle/load:
Voltage regulators 51/84
GPU Temp 30/41
Temp of temp chip 33/40

Cooling
Swiftech MCW55 waterblock 1/2
Swiftech BGA memory sinks
arcticsilver applied to mosfets heatsink

3DMark05 13017
3DMark06 5691 seems low for clocks

Any words of wisdom?

I'm concerned that my core voltages are too high, what you do folks think, am I shortening the life of my card?

Or is my cooling sufficient to the volts?

Any tweaks so I can get my memory to 900 the rated spec?
cheers,

a.

 

[yogurt_21]

odd on my x1800xt i can get my memory to 927 on stock volts, actually i get artifacts with higher voltage and not at stock, I've heard it's do to the mem being heat sensitive more than volt sensitive.

the wierd thing is my x1800 has 1.26ns mem (ie 1000/1.26 ~ 800x2=1600MHZ max rated)
and your x1900 has 1.1ns memory (ie 1000/1.1 ~ 910x2=1820 max rated)
and yours is maxing out at 865 thus 1730 which mine achieved on stock cooling again with worse ns mem.

granted you x1900 easily outperforms mine at the same speed, but it's still odd, i would have thought that the x1900's would easily hit 2GHZ+ with that cooling. the core makes sense due to the 48 shaders, too complicated to achive higher clocks.

I'd recomend doing stock voltage overclocking like I did here

post# 35
one thing at a time thus finding the max the core will do at stock volts, then clocking it down and finding the max for the mem. then adjust the core voltage only and see what you can hit without artifacts or freezing, something tells me that your mem doesn't like the high volts, you might even have to drop the mem a bit to say 1.996 like chew did.

 

[oarsome]

Okay so I've gone back and tried what you suggested

At stock voltages

I can achieve
714/594
499/855

I havn't tried to put them together though

I played some more and continued to bump core voltage up to 1.575 and max core is still 747

How does VDDCI effect the equation, should I leave it stock or keep on par with core voltage?

any ideas?
