My Pencil Trick

[psykoikonov]

OK pencil trick accomplished successfully errr somewhat. My BBA8500LE128 infineon 3.6ns measured vcore=1.63V and vmem=2.83V, after mister HB measured vcore=1.77V and vmem=3.18V. I reboot after changing R3D to 297/297 and sure enough as soon as R3D applies the OC my desktop does a back flip (figure of speach, all the icons and the taskbar go smeared) until I move the mouse. This happened before the volt mod as well. I can't increase the AGP voltage on my MB in my bios. If I turn the clocks down to 295/295 everything is perfect. Has anyonelse seen this sort of thing? Is it just the infieon ram neering it's max speed (277MHz rated, 6.5% increase)? I don't want to go higher until I can clear this up. I'm not loading any other programs on boot. I've ample cooling to do this.

You did a pencil trick to your videocard? Can you tell me where you found an article about that?

Cool I edited that last post.

Ha-ha!

Just another example of it being more profitable to manufacture the exact same card, but with a single, tiny little difference that allows to to put a performance difference between them.

God, I love MBA's. I have absolutely *GOT* to get me one, too...

now if only I could do something like that to my vid card, last time I tried a voltage mod *shudder* my pretty new kyro 2 melted into brown goo (it rhymes....SHUT UP!)

It depends who makes them.

There are a few key differences between the retail ATI 8500 and 8500LE

Two main things apart from clock speed:
- 8500 has 2nd monitor support (DVI) and all the associated electronics, 8500LE doesn't
- 8500 has Infineon 3.3 BGA, 8500LE has Infineon 3.6 BGA

Of course 3rd party cards can be anything. ATI guarantees the cores to run at 250, so that's what most of them are clocked at. If Saphire or Powercolor clocks them at 275 and they work fine, good for them. If they don't work they can't blame ATI.

I think before ATI got the manufacturing process perfected not all the cores would do 275, hence the 8500LE and OEM 8500. As time goes on the cores get better and better, and any newer core should do 275 easily, so the line between an 8500 and 8500LE blurs somewhat. But the real 8500s still have dual monitor support plus faster memory and that serves to differenciate them.

Of course if you only use one monitor, a late version 8500LE is the board to get. I picked up a retail ATI 8500LE 128mb yesterday that ran 315/305 right out of the box all night long. Not bad for CDN$170 (US$105).

What tweaker did you use and if R3D did you tweak the registry settings for the clock speeds only or other as well? I can only get mine to 295/295 before my icons go goffy on boot until I move he mouse. Have you measured vmem yet mine is ay 2.88V which according to infineon should only be 2.50V? I bumped up vcore from 1.65 to 1.78 with no diff also tried 3.18 on vmem and got nothing.

I just used PowerStrip to adjust clock speeds. Whenever I played with registry settings on my 7200 it would only slow it down so I leave them at default now. I'll check voltages when I get home today. Is there a proggy that does that or do I have to drag out the Fluke?

Drag out Fluke and go here <A HREF="http://www.xcl-clan.com/articles.php3?id=29" target="_new">http://www.xcl-clan.com/articles.php3?id=29</A> should be everything ya need just watch you probably have the Infineon BGA 3.6ns and his voltages don't apply to us.

If I had a fluke, I'd drag it out every chance I had. All I got is a "free gift" multimeter from Omega.com. Should have gotten the free mutiplier instead...grumble...grumble...
