Exclamation Re: 8400M GS : Low performences

reg00: base=0xfffe0000 (4095MB), size= 128KB: write-protect, count=1
reg01: base=0x00000000 ( 0MB), size=2048MB: write-back, count=1
reg02: base=0x7ff00000 (2047MB), size= 1MB: uncachable, count=1

??? maybe some mtrr-wizard can say something about this, but IMHO it looks fishy.

third:
[ 355.972000] APIC error on CPU0: 40(40)
<snip>
[ 2002.716000] APIC error on CPU0: 40(40)

ouch, with some sata errors, yay. are you using s3 or suspend to disk?
Hello, and thank you for answering.

Well I do not expect incredible rending from my graphic card, I just want 3D desktop effects to be nice. I have a ****ty Aspire 3023WLMi with a lame ATI X700 on it, and 3D effects are running smoother than on my brand new computer.
You can thus understand I am kind of pissed about this.

I do not use s3. As for "suspend to disk" I don't really know. gnome-power-manager supports it but I do not know how to see if it is enabled or disabled.

As for

reg00: base=0xfffe0000 (4095MB), size= 128KB: write-protect, count=1
reg01: base=0x00000000 ( 0MB), size=2048MB: write-back, count=1
reg02: base=0x7ff00000 (2047MB), size= 1MB: uncachable, count=1

I found out that mtrr's are Memory Type Range Registers but I don't know how to deal with these and don't get your mtrr-wizard thing. (keep in mind I'm just an advanced user, not an expert)

I still believe there is a problem with the support of this card. I've read a lot of posts that were dealing with the same problem on a 8400M GS.

Thank God there is wikipedia so I can understand what IMHO means, we don't use that much in France

Thank you for helping
