Being curious I booted into 64bit. There no agp modules were loaded at all (no agpgart, no via_agp, no amd_k7_agp), but testgart produced the following output: version: 0.100 bridge id: 0x31881106 agp_mode: 0x1f000a0b aper_base: 0xc0000000 aper_size: 256 pg_total: 240640 pg_system: 240640 pg_used: 0 base=00000000c0000000 range=0000000010000000 base=c0000000 entry.key : 0 entry.key : 1 Allocated 8 megs of GART memory start=1377994247, end=1377996514 MemoryBenchmark: 1764 mb/s start=1377996519, end=1377998745 MemoryBenchmark: 1796 mb/s start=1377998748, end=1378001398 MemoryBenchmark: 1509 mb/s Average speed: 1689 mb/s Testing data integrity (1st pass): passed on first pass. Testing data integrity (2nd pass): passed on second pass. But that does not really help me on my 32bit system :-( P.J. -- ---------------------------- Peter-Josef Meisch Mail: pjmeisch@web.de ----------------------------
