8790 Artifacting - Page 11

Under Memory Timings: M10 menu, I have a MEM_REFRESH_RATE setting of 0x20. Should this be changed to 0x1D for a mem setting of 236.25 or just 1D. Thanks.

Just installed, no mod. (How would you mod it?)

But... at first I played for 30 minutes with no problems, right before posting the above. Now it has degraded to the point where I can only play for 5-10 minutes and I get artifacting again. It even artifacts when I play Bejeweled. I was trying to avoid driving down to Sager AGAIN (my extended warranty expires March 2007) but it looks like I'll be taking another trip to beautiful downtown City of Industry.

I just read that you can mod the regular Catalyst driver so I just assumed you could do the same with Mobility, however, the mod that I cam across simply modded the regular Catalyst to work in mobile computers. So it seems it would defeat the purpose to mod Mobility drivers since ATI has so graciously done it for us already, but you never know, it could make a difference. Although, I have not tried it.

Can someone update with results to verify the normal timings work? I currently have my machine at 405/220 as per instructions months ago and I don't have any major artifacting. I would like information on the application of thermal compounds or thermal tape that can be used to replace my old tape. Also, what is the compound/tape found on them memory chips? It looks like some sorta white/yellow pad.

I have installed the Catalyst 5.11 and adjusted the settings via ATI-Tool to 460.80 / 235.80. Ran the Artifact tester at that speed for over 18 hours straight without a single "burp". I have no ida what the "think" thernmal transfer tape is on top of the chips that I described (I think that they are the same ones SEMC references).

Only problem I experienced is the failure to "RTFM" as pertains to making the changes persistent accross boots. Finally figured that out and have been a happy camper with a very cool machine since. Last night I was rendering DVD's and both CPU's were set at 100% load for over an hour per DVD. The machines temps waived between 56C and 58C without employing the "Turbo Fans / Fn+10" mode - Room Temperature was 72F - no extra fans, etc...

This may have been mentioned before but I have been away from the forums since I finally got my computer to work but I sent my Sager in 3 times the first 2 times the motherboard was replaced and the artifacting continued, finally the third time they replaced the RAM.... no more artifacting now for about 3 or 4 months and i game extensively...

ps. I never paid for shipping... if you push hard enough they will give you a shipping label.

G-man, yes that's the tape I was refering to. It covers the video ram (the little silver things), which is why the tape has a sorta baked/burnt look to it (not your smoking, its the chips melting the pad). I'll look into that supplier for replacment tape. Also, I use the latest Omega drivers (2.6.75a), do you think that will hinder my tests? Your post you referenced said that your tests with Ati Tool made the problem worse and then you said it worked. I'm slightly confused. With your timings of 460.80/235.80 or the 432/236, which one works and what is the memory refresh set to (1D, 1E, 20)? Thanks and please respond soon.

Memory refresh remains at 20.

I was confused because when I rebooted the machine it reverted back to the default settings - I didn't set the over-ride to the default profile. When I set the overrids, everything was again A-OK. I tested the 460.8-/235.80 for the 18 hour sequence that I indicated above. Now, I wasn't playing any games; however, I was rendering video (don't know how much that counts). I found that resetting the memory refresh to a value other than 20 made the artifacts reappear after as little as five/six minutes or as much as an hour depending on what I was doing. Since changing it back to 20 - no problems have been encountered.

Hope that this helps you. I'm not sure about the Omega drivers or how they would equate to the catalyst's.

The pads were discolored by tar - I was able to remove the "gunk" and the resulting pad is an off-white/yellowish color.

Edit: FOrgot to mention - One of those little silver "things" bottom right one was completely covered with gunk & was dark brown/black in color before I started the cleaning process.

Okay G-man so let me get this straight:

You are clocking at 460/235 at mem refresh at 0x20 and it works fine?
If not correct, what times work for you. See, I've got your times and refreshes all jacked up in my mind.

I am running at 405/220 at 0x20 and my system works fine and runs cool after each monthly cleaning. I'm hesitant to modify my timings higher unless the new ones are really and truely the best ones for extending the lifespan of my machine since I'm jobless right now and buying a new machine is the least of my worries.

Just thought I'd share my pain with everyone.



Yes, that's me and my wife Christmas shopping... online... via instant messaging (and a friend in San Francisco just chatting). No, that is not the source of the aforementioned pain.

Those settings are working for me. Remember, I cleaned off all points that has a potential contact with the metal plate below the keyboard and used thermal tape between those componets and the metal plate. I "futzed" with a few other setting; however, the ones that work best for me right now are 479.65/235.06. Both a cool machine and no artifacting or other problems. I truely think that the settings must be customized for each unit and what works best for me might be really really bad for you. So caution is the word....

That was about the way mine looked at default settings and beofre the cleaning and use of thermal tape.

And you're saying that solved the problem? Wow, I'm happy for you. I think mine is permanently boned. I've got AS5 on there now and while everything is running much much cooler (should've done it ages ago), I'm underclocking and reducing hardware acceleration and I still get corruption. Can't send it in now though because I need it.

OC/UC Noob Question about ATI Tool

Are you guys following some kind of formula or ratio when experimenting with core and memory clocks? How are they related to each other, and to the memory refresh rate?

Not to rub it in but hope you got the extended warranty if you cooked it as they can't get parts to fix it anymore

Who did you send it to for repairs? Sager? Or someplace else referred by Phillips?

I do have the extended warranty through Warrantech/Repairmaster, good til April 2007. However, thanks to the info in this thread I didn't have to send it in. Added some Arctic Silver and clocked down to 405/220 and it's running like a champ--not a single misplaced pixel for about a week now.

I called Sager directly and they quoted $440 to refurb the mobo + $80 labor. If you send it in yourself Warrantech only reimburses you up to $350, so I have to do it through Warrantech if I don't want to pay for it, but I can't be without the computer that long. But, looking at that other thread, it would be even nicer if they just replaced it with the current model... but somehow I doubt that will happen. I'm good for now.

load up ATI profile

Once you find a core/memory underclock setting that appears to work, how are you getting it so that the new profile is loaded automatically each time you start up?

Settings > startup > load on windows startup >

then are you doing it through the registry or on the start menu for all users?

What advantages do one have over the other. If I "tweak" it some more and I do have it starting up in the registry, will the new settings be automatically transferred?

As much as I hated doing it, this seems to be working for the time being.

I use the ATI tool. Just download and set different profiles. Their is an option to load profile on startup. Good luck.

In the ATI tools setting you have to select OVECLOCKING in the first pull down. The select your profile and have it startup wheith windows. It's kind of hidden.
