3DMark06-7089 <---NOT BAD FOR A PENTIUM HUH??



For 24/7 use I have it at 720/828 1.400/2.102/2.102/1.500

[darksythe]

my latest update.
i managed to get my card runnin at 715/830 @ 1.45/2.18/2.18/1.5[stock HSF]
not really sure whether that can be considered good.
btw, my 3d mark 05 scores are only 11686 with an Opty 170@2.78
kind of low right?

is ok what .. defrag ur hd? restart ur windows?

mine can do up to 725/835 1.45/2.13/2.13/1.5

higher also can but score less, maybe have to increase vgpu a bit..

[darksythe]

blek irenic.
how come thats ur max? im so sure u can do better than that.
and ur 0550 UPMW is just a gem.
btw, anyone else noe why im doing so badly with my 3d mark scores?

Whenever I up the voltage on the GPU pass 1.50v I can't get the same mem clocks. It artifacts like crazy. Could it be that my PSU is crapping out on me??

Edit: Now, it doesn't like anything above 840 on the mem. Is Sapphire BIOS better than ATis??

[cantankerous]

they are identical as far as I know.

[ben805]

can you guys loop the 3Dmark06 with your overclock at all? mine is only clocked up to 700/830 1.475/2.13/2.13/1.51 but 3Dmark06 didn't finish the overnight loop and I woke up to a black screen and had to reboot. Though gaming BF2 for couple hours is not a problem and the gpu temperature is only around or below 60

[nicepun]

Well, I guess I can't really complaint since I do 720/828 @ 1.400/2.101/2.101/1.500 with temps 31c/38c !

Edit1: I just figured out how to OC my card. I leave the GPU voltgae @ 1.400v, but change the VDDC/VDDQ/VDDCI to 2.201/2.160/1.515, respectively to achieve 873, then after it's set, I go back and raise the the gpu to whatever voltage I want for it and raise the core accordingly. I will post results later. I knew card had a little left.

Edit2: Results have been posted on reply #251. I'm not sure if anyone else uses this method to OC their card. Also, I'm using ATi Tool 25b14 only.

[fallguy]

Just got 2x1900XT's. Hope this works on both.

[fallguy]

Is there a way to do this within Windows? Where are the instuctions..

[LivingL@rGe81]

This is the max I think my cards got on the stock cooler!!!

darn i need to work on my 1900XTX man,
just dun have the time nowadays.
nice stuff u got there dude ^^

[neologan]

my xtx is artifacting like crazy as soon as i go around 675MHz.

So my question is, what's happening to people when they hit their cards core limit, are they getting a few artifacts and then lowering the clock a bit and then all is fine, or are they getting what i'm getting - complete corruption even after i lower the clocks and voltage back down, and this is in windows as well, all my icons are messed up.

i'm

[cantankerous]

for me I don't get aritifacts at all. If I push the card too hard I simply get a hard lock up or a vpu recover where my monitors go into standy mode with a solid black screen forcing me to reboot the system upon which al is fine again.

I can see a normal XT having issues on a core that high as they aren't normally known to go quite as high as an XTX but your XTX should do that fine? I have to ask what is your volts at when trying to achieve that core and what program are you using to overclock your card? ATI's overdrive tab allows you to go as high as 689 on the core and still be under warranty. If CCC is having issues getting your core I would suspect something is wrong with your card and it should be warranted. Using CCC I got to 689 np and with atitool, with 1.400v on the core I am running now at 685 clean and stable after looping 3dmark 01 and 06 for a couple hours as well as letting atitool scan for artifacts for a couple hours too.

How long have you had the card? When has this started happening?

[neologan]

I've just got the card now and have been playing with it. I'm using ATI Tool beta 14 with 1.425v vgpu. I'll try the CCC instead and see if it holds up ok.

[neologan]

small update, using overdrive i could crank it up to 689 with no issues, it passed a few runs of the Doom III timedemo , hmmmmm i seem to have a real problem in ATI Tool.

Hello peoples.. i have just switch my X1800XT for a X1900XTX... really nice my first result on air impressive me..
X1900XTX one hour installed air cooling, 3D 05, 690/800 : 12'438
http://service.futuremark.com/compare?3dm05=1914641

my ask.. with the X1800XT, we have need decrease the voltage on memory for have more of 900mhz ... is same with the X1900XTX?--

Other what voltage are fine for try get 800/900mhz??

( watercooled of course)

really impressive difference between the X1800XT and the X1900 in performance.. really nice..)

[Eastcoasthandle]

Is it just me or is it that VDDCI seems to be some sort of voltage gatekeeper for MVDDC, MVDDQ & VGPU? I can do:
VGPU 1.425
MVDDC 2.108
MVDDQ 2.108
VDDCI 1.486
core 720/mem 832.5

On 3d06 FPS is flip flopping all over the place, meaning that FPS is consistently changing every second on the second.
If I increase VDDCI to 1.491V FPS is more stable, meaning that for a few seconds it will remain steady then either goes up and hold for a few more seconds or maybe dips down but still holds for a few seconds. I am still experiementing at lower clocks for now. However, has anyone noticed this? I also noted if I try to do VDDCI 1.500 (at the voltage & core/mem settings noticed earlier) it will simply lock up in game.

Though gaming BF2 for couple hours is not a problem and the gpu temperature is only around or below 60

I had the same issue. 3dmark2006 was freezing overnight, while i could game for hours and not have a single hiccup. I had to bump the core voltage from 1.425 to 1.45 for 3dmark2006 to stop freezing. This is at 698/792.

I have to lap my heatsink, i get ridiculously high temps of like 70c under load.

Some ask for OC the X1900XTX...

Ok no prob so far, is a damn OC'er: 772/891: 1.475V , 2.192, 2.192, 1.5V No corruption no artefact.. clean image
3D'05 13'451: http://service.futuremark.com/compare?3dm05=1916716 ( link will certainly not stay longer available, but i put it for the moment)

I need certainly increase voltage then for go higher, but i begin just play with the card..


--edit: i have a strange thing happpend, i have not have time test more but perhaps somoene can help me understand this..

After having bench at 772/891, i decided increase a little bit the speed memory and core.. i launch at 802/900
1.575V,2.25, 2.21 and 1.5V.. during all the bench i have thnk kill my score.. the peak of FPS was incrediblly high, last test with 190FPS ( when the snake attack the flying boat..), peak really higher in the place i look in general for see if there's a prob or not.. and the score appears.. really under the score i was having.. i ahve think have forget the AA or anything else.. it seems not ... any idea? Is this can be caused by a instability?not enough too much voltage? But the 3 benchs have look more speed..

I put WC on my x1900xt


(more details here: http://217.172.39.212/~forum/index.php?showtopic=139223 )

What is the maximum safe temperature for GPU? PCB? Vregulators(mosfets) on x1900?

This card runs into a wall above 74c, it's circuitry has little headroom above above that.

Just got a new His x1900xtx card. I have onlly done some tests and it seems to oc pretty good.

His x1900xtx
Water, TherMaxTech XtFlux-GA
VGPU 1.425
MVDDC 2.124V
MVDDQ 2.086V
VDDCI 1.486V
760/880 3DMark and Ati Tools stable.
Got 12,8k in 3dmark05 with the cpu in only 2.8ghz.
Maxtemp with these settings 3dm01 nature loop 30min is 47c (atitools)

24/7 i go:
VGPU 1.375
MVDDC 2.124V
MVDDQ 2.086V
VDDCI 1.486V
735/860

More results will come when i get a new opteron 165.
Tonight i'll test some 06,03 and 01 too.

[Lane-k]

Yes the HIS Oc well.. i do 772/891 without prob.. i can OC more without artefact.. but my score dercrease lol.. i have do 810/900 - 800/900- 820/910 and my score will not increase in 3D 05..
I m at 13'505 772/891 after i m only at 13300...lol
PSU?.. CPU i don't think..any idea?

those are some nice clocks... what is the highest you can OC?
