X1900 XT overclocking

[MingoDynasty]

Hello. I'm trying to overclock my X1900 XT using Ati Tray. Does anyone happen to know the highest temperature it can go? Btw, I'm tryin to overclock with the stock cooler. Is that bad?

stock clocks, and maybe a little above.. 640 or so, there's probably no problem whatsoever at 90C(normal for R580), but the higher you try to go the cooler it needs to be..

Just use Atitool to overclock and make sure you Scan for Artifacts to see if the oc is stable. You can monitor temps, adjust fans, save profiles, etc with atitool.

I hit 83C on accident once while testing the maximum core clock. Just be sure to manually set the fan control options. I try to keep my 1900xt from going over 70C.

1. How do you manually set the fan stuff?

2. I tried running ATiTool but it said my card was not supported (X1900).

Anybody here??

Hmm x1900 is supported i had a x1900xtx and it worked.

To manualy adjust the fan speed, when you open the atitool software go to Settings there is an option for adjusting the fan speed manualy and by temperature.

Okay I got teh latest ATiTool. Problem was I was using an uber old version. Everything is all set, but when I click on find max core, the computer freezes after liek 2-3 seconds and the screen goes blank.

What temperature is the atitool reporting when its at idle and when it starts to Scan for Artifacts?

Clocks: 654core/729mem

Temps: approx. 50C idle with normal fan/approx. 46C idle with full speed fan
68C load with full speed fan

The x1900xt comes clocked stock at - core 625 and mem 725 (1450).

You have the card oced at core 652 and mem 729 (1458). I dont know how you can get core 27MHz in 2-3 seconds when you press find max core unless you had it oced already at around core 650. Probably the 652 is the limit with the temperature at 68C. Just like some of the other users have said that around 70C it hits the brick wall. I had the x1900xtx and best that i could oced it and be stable was at core 729 mem 828 (1656) with zalman cooler (stock speeds at 650 and 775 (1550)).

The idle temps look ok to me.

Seems kinda weird that such a premium graphics card can only overclock 25 mhz. That's why I'm thinking it should be higher, or maybe just something wrong with something else. To achieve that 650 core, I actually manually raised it and ran Scan for Artifacts for awhile. The Find Max Core still freezes my computer.

 

[sarsoft]

Yes that seems to be a bit low oc with that card. Cooling the card does play a big role in stable oc.

Try to start from core 625 and press find max core and see where is goes from there and monitor the temps.

One more thing that can play a roll and it is the PSU. If the card is not getting enought amps it could be a factor especialy when under the load. What kind of PSU do you have and state you whole sig?

The following link has all the info you need to get the best X1900XT overclock:

I used this guide to OC my X1900XT, and as you can see in my sig, the results were better than I had expected. Think twice about changing the stock cooler. The beauty of the dual slot rear exhaust design is that it removes GPU heat from the case, whereas other designs only recirculate the heat they create, which can be a major disadvantage when you're gaming and trying to keep an OC'd CPU cool. 8)

Dunno about you, but a simple Scythe Inf + Silverstone brings my cpu temps to only about 28C idle. Plus, the Silverstone fan isn't even up all teh way.

My rig:
E6300 overclocked 3.01ghz stock vcore
Scythe Infinity + Silverstone + AS5
Gigabyte DS3
2x 1gb Corsair XMS DDR800 5-4-4-10 (not 100% sure of timing stability)
2x 320 GB Seagate 7200 RPM 16MB cache PMR 3.0 GB/s SATA
NEC 3500a DVD-RW CD-RW DVD-DL RW drive
CoolerMaster 550W
Thermaltake Armor case (4 case fans)
3DMark06 - 6720 marks

Your PSU is not the best but will be enough.

One more thing... make sure that CCC is not running in the background and also disable it at startup and then try ocing the card.

I hope that helps.

My CCC stopped working a long ass time ago (piece of crap Catalyst). That's why I went to other methods of overclocking (ATiTool). I dunno what process CCC takes up in startup or msconfig, but I'm somewhat sure it doesn't run at startup.

I followed CompuTronix's MadShrimp's X1900 overclocking guide. http://www.madshrimps.be/?action=gethowto&number=1&howtopage=160&howtoID=61
With these new clocks, 634/747 (which are actually supposed to be default), I reached an all time high of 6970 3DMarks :O
Before I couldn't even break 5000 3DMarks. The only thing I'm concerned about now is stability and artifacts. I remember I destroyed my friend's 9800 XT card accidently due to constant overheating (I'm guessing its fan broke, and I was uber noob and didn't know how to monitor temps), but he wasn't too pissed cuz he already had a 7800

The screen typically does go black during this... It is trying to find the fastest OC\temp. Let it sit for 5-10 minutes and if it doesn't come back up reboot.

 

[MingoDynasty]

Well I'm attempting to overclock manually right now (raise clock then scan for artifacts until the temp can't go any higher) according to the madshrimps guide. Right now it's topping off at around 71C with full 100% fan.

 

[CompuTronix]

That's exactly how my X1900XT temps out; 71c @ 700 GPU / 1700 GDDR3, 7003 3DMark06. 8)

Update: With full speed stock cooling fan, I can only reach 661.5/801, stock voltages, 72C max Scanning for Artifacts. I'm guessing this is my limit? :\

 

[CompuTronix]

The MadShrimps article has some OC examples with ATI Tools software volt mods, which I performed, enabling the card to reach peak OC. I'm traveling out of town, so I'm on my laptop, otherwise I'd give you my voltage settings. If you're interested, PM me, and I'll give the the info over the weekend.

Sounds like a good idea, but I reached my overclocked settings at 72C load, which is high enough according to the range of acceptable temperatures. Pushing the voltages would likely even bring it higher. Right now I need to save up my money to repay some people I owe, otherwise I'd get a HR-03 or an Evercool Turbo 2, or maybe watercooling. So I guess I'm stuck with stock for awhile.

Fair enough. You've done very well, but stock works great if you setup an RPM / temperature table in ATI Tool, which controls the fan in 8 steps. I have mine tweaked in this way, so it idles at 23% RPM, and reaches 100% at 69c.

 

[MingoDynasty]

Yea thanks. I've tuned my fans too so it idles around 40% fan speed, and when it goes over 70C the fan cranks up 100%. I just wish you can change the temperature graph scale; who would want a temp of 90C and when do you ever see a 30C gpu?
