[Solved] AMD Dual Core Timing Issue AKA Mouse Bug - Page 29

I've reverted to using CPUS=1 until a proper fix has been found

Stability is more important to me than performance. Nothing worse than an app quitting and losing work!

Voyn1x, if you haven't already, try Leo4Allv3. It might solve the problem.

However, I use zephy's release and it seems to work fine, even after about 10 hours of uptime.

You seem to be one of the lucky ones Puttabong. My machine runs great, but as soon as I start loading files into Photoshop, run a few filters and layer styles, the bug appears and a reboot is necessary. I'm toying with installing Leo4All until my Intel kit arrives.

@Puttabong, yeah i've thought about it - i'm hoping it might of fixed itself after updating to 10.5.3. I haven't got around to trying it again without CPUS=1 yet.

I'll report back when I have.

[cite] snyder9:[/cite]Unfortunately about 5-6 hours later, the mouse movement bug reappeared along with some weird behavior in Safari and segmentation errors repeatedly crashing Adium.
I changed the ACPI settings to S3 but this didn't seem to help.
Installed the 9.2.2 kernel, and though the system felt a little smoother - the mouse bug was still persistent.

Would this bug show up if I install leo4allv3?

I am using Leo4all v3, and i have no problems, so i guess you can give it a shot.

Can you tell me what all you have changed in the BIOS (if anything) to solve the problem?
Memory Timings, APIC, etc.

The stuttering problems usually for me occurs after watching 720p content which puts a lot of strain on my 4200+X2 with VLC.

Also, does it matter that I have 512mb x 4 running in dual channel in my system? I read earlier in this thread that someone solved the problem running 3gb instead or 4gb. Is this the same sort of problem?

Your memory configuration should make no difference the 4gb problem is caused by 32 bit limitations. As for solving the mouse movement bug as far as I know the only cure is still the idle halt in com.apple.boot.plist "see earlier in this thread". If you use it keep a close eye on your processor temperature.

I thought IDLEHALT=0 had cured it for me initially, but after working for a period of time in photoshop the jumpy mouse came back unfortunately

It only seems to delay the problem.

Have you tested the keyboard mouse? Go in System Preferences -> Universal Access -> Mouse and switch on the keyboard mouse. Now you should be able to control the pointer with the numpad keys.

Have you a function 'USB Legacy support' enabled in BIOS? Some computers have problems with mouse and/or keyboard if it's enabled.

Exactly the same problem here mate.

Hm, the only problems with mouse I ever had were artefacts caused by a wrong gfx driver. On 5 machines, all using Logitech PS/2 mouse/keyboard combos. But USB works too.

I read a long time ago that AMD stuttering problems could be solved to set the CPU multiplicator to a .5 value if the BIOS supports this. so 10.5 insted of 11. But this was maily ment to Dual-Core CPU problems.
