I think you need a schroud. The dead spot of the fan is too close to the core and to the fins of the heatsink.Quote:

Oh oh artifacting at 600/700 after time isn't good. That is what I was afraid of. It seems everyone is so happy with the clocks of this card INITIALLY that they leave it at that. Very few have probably run extensive testing at those speeds for long periods of time to see how it keeps up which is may not do so very well. Let us all hope it is just heat and nothing else such as the core being weak or not taking well to the voltage increases.
The Fatality version is all copper and I have ordered that with my card for testing. The extra fan speed can't hurt anything except my ear drums. I will have it on a controller anyhow and I too plan on using Ceramique over stock or silver even.
Dnottis, you say 600/700 starts to artifact after awhile. What can you run your card at 24/7 without any artifacting or issues?

Well max overdrive clocks are 575 / 550 the system rebooted during 3dmark 2005. Alright now this is getting frustrating.
hmmm well the voltage tools may have issues or are incorrectly going about doing their job and the card reacts weird to it. As far as I remember ATI guarantees their cards to run up to the max CCC speed as during their testing of the cores this is included. It is an option that is freely available to us and ATI can't have RMA's because one of their features don't work. They also shouldn't need a voltage increase at the max CCC speeds cause ATI themselves have no voltage option in their drivers. Try not running the voltage program and run at max CCC speeds for awhile and see what you come up with especially in games over long periods of time. Get us a score in 05 if you don't mind either. Remember as well, the ceramique will take a couple days to properly cure which could bring down temps even more. I may suggest putting ceramique on your memory instead of the pads if you are using stock cooling as I did this on my current X800XL with Silencer and it works better than the stock pads on the silencer.
Good luck. Dnottis it is your results that I look forward to seeing as of now.

haha I need a voltage bump on the core to get max CCC speeds to finish 3dmark.
oh wow. A bump up to what from what?
Are you running sapphire OEM card? Trying to remember.
If you dont mind find out what max mem and gpu you CAN do artifact and crash free without a voltage bump.
I got the same :banana::banana::banana::banana: over here. I'm now running stock volt and 550-500. If i go higher on the mem i get artifacts card is screwed like hell :(. I had it with this one :slapass: Its a XT for me next. As soon as i can get one i'll dump this crap ass card.Quote:

Ah - being a slave to the OC.
Alright guys here's a tip to check things as you go.
Download and run RTHDRIBL, thats the app that will bring your GPU to it's knees. It runs windowed so you can play with volts and speeds.
Running core above 1.2v I get instant artifacts, so I backed off it was clean at 1.175v, but I dropped it further to 1.15v and am running 3dmark 2005 now at 625 core / 750 memory with core voltage at 1.15v and the memory at 1.9 stock now.
Maybe I was giving it too much juice. Once I got above 1.2v there were crazy artifacts - 1.3v was really bad, but dropping just the core voltage to under 1.2v everything cleared up. Using RTHDRIBL can at least get you to find where you need to be without corruption.
Still working on it... these might be easier than I thought to overclock - be sure not to give it too much voltage, from these tests it seems that it may be the case. Now Im working on seeing how stable 1.15v on the core is at these speeds - but at least the artifacting is gone.
Also, I notice idle temps are like 54 deg c, but the load is only 68 deg c. My GTX with stock cooler swung from 54 - 78 deg c and with the nv silencer from 42 - 58. Seems these cards run hotter but there is less of a delta between idle and load.
Thanks for the update Dnottis. Perhaps too much voltage was the key, if that is the caes than that is great! Less volts for same clocks. Now that the artifacting is gone let us test for stability again hard locks, vpu recover errors or drops to desktop when playing games. Keep us posted on how far you get and at what volts. As well let us know how long you ran your tests.
Astennu, 500 on the mem is pretty bad and also leaves me confused. The 1.4 chips are good up to 700mhz stock! IF you can't get over 500 then those chips are running worse than 2.0 chips. The only thing I can think of is that perhaps it isn't the memory but the mem controller on the card that is holding you back. I remember when the whole mod your X800 VIVO to XT craze came about it was the same deal. The cores were weakened, rejected XT cores that couldn't keep up to both high gpu and mem speeds due to a fubared mem controller. IF you went too high you got black lightning etc as artifacts.
Dnottis, when you had artifacts from high volts what kind of artifacts was it? popping pixels, flashing textures, weird colours, checkerboard, dissapearing textures, black lightning etc?
Im just absorbing all this so I have some key points to work with when I receive my card.
I dunno anymore - less volts got it through 3dmark 2005, then I run 2001 SE and instant artifacts. My efforts overclocking are becoming futile.Quote:

strange as 05 and RTHDRIBL are very GPU intensive as compared to 2001 which is mostly system dependant. You would think the first two would cause artifacts over the latter two.
It is too late to cancel my order even though I am having second thoughts on this card but we will see.
What you should do is this. You jumped straight into overclocking the minute you had the card. Did you even check to see that it runs properly at stock? Perhaps it wasn't even very strong in that respect.
When I get my card I am going to run it stock volts/stock clocks for the day to make sure it is as it should be default before I do anything else. As soon as that assessment is made I am jumping straight onto the ceramique and zalman to be sure I get a cooler card right from the getgo.
Again thanks for your findings and let us know of any updates you may have.
hm...........the results are impressive but seems like there're problems that'll arise after some stress testing.
Should I be getting this card? I was thinking of it but these issues? :dunno:
If you can deal with less than XT numbers - but on par with stock or slightly better than GTX performance - without shimmering and better AA - then yes. Also, expect to replace the cooler with something more efficient.Quote:

Seems than CCC max memory 550 with core at 560 is ok at stock voltage. (not max CCC for core though).
Newegg was showing X1800XT next in stock 11-8-05 - but I kept refreshing the page.
I just got one!! Get them while they are hot at the EGG.
EGG doesnt ship to Canada the whole they were suppose to seems like a lost cause as they are over a month late from the opening of newegg.ca.
So stock voltage you can confirm 560/550 absolutely stable and artifact free? Max core for CCC is 575 so you are only off a bit. 560/550 would kill my dads X850XTPE which already plays games quite well even with 565/600 on his card.
Would 560/550 on an X1800 be better than a GTX?
Absolutely!! I've played FEAR, BF2 at 560 / 550 stock volts.
If anyone is looking for a X1800XL, even in Canada, I'm going to sell this for $360 shipped.

the mem needs more core volage to go higher, did you forget about that? I can do 550/775 with core at 1.2v and mem at stock v. If I leave core at stock voltage mem wont go above 550 without artifacts. So its not that the memory is crappy, its just designed to work hand in hand with core volage.Quote:

Yes, I have the Zalman VF700CU here waiting for it that I previously bought for my x850xt.
If the XL is really that good, then I'll wait till they're on sale for <300, may be @ the end of this year or early next year :)
349$ Damn, here in Norway it costs 434$. :fact:
Lucky bastards ;)
Hey Astennu, why don't you try this and see how your card fares at these settings as you seem to have the most amount of problems with your card. Dnottis is back on stock cooler with stock volts and is 100% artifact free and stable at 560/550. See if your card can do that. Instead of striving for XT speeds right off the bat plus voltage increases on early and somewhat buggy software see what your card can do stock as his is clearly doing well. I am striving for the same thing when my card arrives as I was told it just shipped today. 560/550 is nothing to sneeze at with this more efficient design of the X1800. Most if not all games should play beautifully like this. If I could at least do this stock volts I would be happy. Anything else will be a bonus but I will be going ceramique and zalman from the get go.Quote:
