[Openchrome-users] slow GART memory - CN700

[Dmitri Khokhlov]

Hi,
 
I have EN15000 board - C7 1.5Ghz, CN700 & VT8237R (Optimized settings in
BIOS). FC5 with kernel 2.6.17.
The testgart shows extremely low memory performance:
 
version: 0.101
bridge id: 0x3141106
agp_mode: 0x7000a0b
aper_base: 0xe8000000
aper_size: 128
pg_total: 224768
pg_system: 224768
pg_used: 0
entry.key : 0
entry.key : 1
Allocated 8 megs of GART memory
MemoryBenchmark: 14 mb/s
MemoryBenchmark: 14 mb/s
MemoryBenchmark: 14 mb/s
Average speed: 14 mb/s
Testing data integrity (1st pass): passed on first pass.
Testing data integrity (2nd pass): passed on second pass.

dmesg:
 
Linux agpgart interface v0.101 (c) Dave Jones
agpgart: Detected VIA P4M800CE chipset
agpgart: AGP aperture is 128M @ 0xe8000000
 
What could be a problem here?
 
Thanks
Dmitri
