I want to know wich is more stable overclocked and their max speeds

More about : wich overclocking 7900gtx 1900xtx

ima buy a car Fan/radiator for that card


-X1900XTX


yeeeaaaahhhhhh

Are you sure? I thought the whole 7900 GTX problem business was that the factory overclocked cards (which you know are hardly overclocked at all, maybe by 50 MHz or so) were causing programs to freeze up for a minute or so at a a time.

I am not sure which is a better overclocker but what I do no is with ATITool you can change the vgpu to allow for higher clocks (proper cooler permitting). I think on the 7900GTX (at least it was on the 7800GTX) you had to solder some resistors on them.

Stock cooling on the X1800XT or X1900XT can achieve around 725MHz core and 1700 MHz memory which is spraying some pixels on screen.

i read an article that might help u decide if u want the 7900GT. Check it out, its amazing! read each page to really get the feel for it.7900GT

overclock it to what? At this level they are both the fastest single cards, and you are worried which one oc's better? makes no sense.

If you wanted to get the gt/gs (or ati equiv) version of a given card and wondered if it would reach a level equal to the gtx/xtx version then I see the logic, but at this level you are saying "how high can i get" w/o having a unit of measure.

I could say "you can get up to 14billion pico-pajixels" but you have no frame of reference, so it means nothing.

If one oc's 50Mhz and the other 25, they are such radically different architectures that the 25 may still outperform the 50, or you could see no gain at all in a real game. Plus there is no certainty that YOU would achieve the same oc.

You need to buy based on the architecture, which is by nature based on what games you play... once you figure that out, and you have the $ to get the top end one for said arch, just get it and be secure knowing that it is the fastest.

sorry, end of rant. :roll:

exactly... err :oops:  is it
Word! :wink:

I concur... the 1900xt is a good card. Not like the Nv gt vs gtx that have different chips/mem, both 1900s are exactly the same except for clocks.


...and ya, dont really care about the size of my e-peni$... (not that I have any complaints! :o  ) I do use bungholio and others to see where an oc gets me relative to my "old" speeds, but dont usually compare to others unless diagnosing issues on my system or helping others w/ similar prbs.

I do have plenty of TP though, just in case there is a bunghole that needs it...

oc'D MY x1900xt to the max settings in ATI tool (690 GPU and 1600 mem). I use the new Zalman VF900 cooler and the ram sinks included in the Zalman package. No artifacts and game play is clean. 3DMark 2005 is 11,080 on a AMD 4000 with 2 gig ram and a Asus A8NE.

I overclocked my X1900XT on stock cooling to 690 core and 1600 mem then overclocked my 4000+ to 2.6ghz. After running 3dmark 05 I got a score of 11,700 marks. I guess I have a pretty darn good running system 8)

After adding some more case fans and an aftermarket fan for the X1900XT I am able to game at 702 core and 810 mem when playing Oblivion, so far it has been stable with no crashes after extended game play.

I have had my HiS X1800XT overclocked to 690/1600 for just over 6 months straight now, and no problems with heat or image (artifacts)!
May 1, 2006 6:34:29 PM

I had my 7800 GTXs at 520 core (could have gotten 535ish had I tried) 8O

I may have Nvidia but I recomend ATI... I love market timing issues

x1900XT oc'ed to 760/1710
x1900XTX oc'ed to 790/1740

Both using the stock voltages. The x1900XT is using a Zalman VF900 while the x1900XTX is watercooled using an Alphacool NexXxos NVXP3 ATi block.

With a volt mod the 7900GTX will overclock higher, but the X1900 has the ability to adjust voltage through software, making it more overclocker friendly.

In Nvidia the GT's are more overclocklable than the GTX's. I manage to clock my 7800GT from 425/490 stable at stock cooling. The GTX on the other hand only goes from 460/485 stable at stock cooling. How I don't know the cheaper card was able to be clocked higher and both this cards are BFG and are already with factory overclocked.
May 1, 2006 7:44:54 PM

But the 7800GTX still outperforms the 7800GT at those speeds.
May 1, 2006 8:05:51 PM

yup, more pipes... the big glaring diff between Nv's top 2 and ati's top 2 are that ati's are identical architectures/features and Nv's are not.
May 1, 2006 8:11:57 PM

Hmm I got my 7800GTX to 490 on stock cooler and 535-540 on water.

Dude please tell me how in the hell you got the X1900XT clocked up that high! I can only hit 710 on the core and 1630 on the mem before artifacts! I have tried raising the voltages but no matter what I cant get higher :evil:  My card is only getting up to 68 celcius so I know its not heat!
