Hallo Leute
könnt Ihr löten?????
es gibt eine Möglichkeit die Streifen bzw. Grafikfehler loszuwerden
2Widerstände müßt Ihr tauschen und die Spannung geht hoch und Ihr könnt weiter hoch takten.
Hier die Daten:
1) First, decide wheather you have a oem(250/250-LE)card, or a retail (275/275)card.- powerstrip 3.1 or rage3d tweak will show you this.(If you're having problems at this point, stop.)http://www.entechtaiwan.com/ps.htm
2) Second, review the posts to determine which resistors need modification for voltage increase.http://virtual5.nebula.fi/~efidata/...i/vmem_res2.jpg

3) Third, review the posts to determine what replacement resistor is required for your desired voltage increase. (REMEMBER- OEM AND RETAIL CARDS REQUIRE DIFFERENT VALUE RERSISTORS!)

4) Forth, remove and test removed resistor to determine existing OHM value.
5) Fifth, choose desired replacement resistor and test it for actual value. (Note: resistors may be placed in a series to get desired resistance)...You can get some resistors from http://www.maplin.co.uk
Part Numbers:
M1K8 = 1800 Ohm 0.6 Metal Film Resistor (for Memory Mod). If you want a higher overclock then try a M2K (2000 Ohm) resistor.
M910K = 910 Ohm 0.6 Metal Film Resistor (for GPU Mod)
They cost about 7p each but you'll have to pay about 3.00 UKP for postage. Also in the U.S. Radio shack sells them.
6) Sixth, using a spare female fan or CD-ROM cable lead..(http://utenti.tripod.it/Cifer/photo.../8500_mod_1.jpg)... solder 2 of the wires to the pcb location of the removed resistor.
7) Lastly, insert resistor into appropriate socket/s and insert card into m.b. Power up with voltmeter(-) already attached to case or agp mounting screw and quickly but carefully touch (+) end of voltmeter to the VMEM pin (downside pin of capacitor)to get voltage readings d/c. http://virtual5.nebula.fi/~efidata/...mem_voltage.jpg - You should be within the voltage specs on the above table for an oem card using the chosen resistor value.
-Good luck all!
