How is the ATI BIOS editor coming along? - 2006/03/02 22:10
I was just looking up the memory stats that the X1900XT carries, it's very nice, and underclocked against spec significantly. We should be able to increase memory clocks to 900MHZ, but power could be an issue.
Question is if you loosen the timings a bit to work at higher clock rates if you could reach 900mhz which is a 30% increase then http://www.samsung.com/Products/Semiconductor/GraphicsMemory/GDDR3SDRAM/512Mbit/K4J52324QC/
