[Solved] AMD Dual Core Timing Issue AKA Mouse Bug - Page 42

taikn · #**411** 07-10-2008, 11:20 AM

Hi everyone!

My specs:
Motherboard: Asus A8N-E (Bios 1013)
CPU: Athlon X2 3800+ (2Ghz)
Memory: 3Gb (2x1Gb, 2x512Mb)

I've used in BIOS auto-overclocking profile which sad - '10% overclock'.
So my CPU was 2200Mhz
BUS Speed 220Mhz
RAM 440Mhz
and HT Link 1100 Mhz

When i installed Leo4All v3, i started experiencing mentioned above problems, so i switched to one core and updated my system to 10.5.4 and kernel 9.40 without problems.
Then i've manually overclocked my system, so i've set
Bus Speed to 240 Mhz
Multiplier to X10
HT Link to X4 (960 Mhz)
and RAM running on a divider 240/12

Then i removed 'cpus=1' flag, and system was up for abt 13 Hours, Transmission Downloading, Photoshop, stress tests and so on. I haven't noticed any problems. So i think for me it was HT Link: if it is above 1000, then system becomes unstable.

P.S. In 'Hardware Overview' next to 'Total number of cores' it shows 1? But in 'Activity monitor' i've two cpu graphs?
Is the second core recognized?

It is recognized, System profiler doesn't show the infos correct. My system is also overclocked, from 2.6 to 2.86 Ghz.

thats normal, if the activity monitor shows two cpu's, the system uses both cores

so after 20hrs hardcore test, leopard runs without any of the anoying issues!
no mousejumps no crashes!
try to raise your memory CAS settings to 6 or higher, if i lower them back to normal (e.g. CAS 5) i got back the mousejumps and crashes!

I'm not sure how to check the HT speed, but I've set the mulitiplier to 5x, so with my bus frequency of 220 MHz it should be 1100 MHz. I'll see what happens.

Is anyone able to record the movement bugs?

Well i can tell you, when i start posting here i had less errors with both cores and i had it overclocked.

I have a 3800+ X2 2ghz OC @ 2.6ghz with a 333mhz ram @ 420mhz.

now that i took off the overclock, i have my problems with dual core, so yes, overclocking reduces our problems.

I could try increasing memory timing but i dont know anything about it to be honest.

naquaada · #**416** 07-10-2008, 07:50 PM

You have 333 MHz RAM? It is labeld 333 or does your board not like it? I had on my Asus boards various problems with different RAM types, I have always bundles with 3200 speed, but they only work in correct combinations. Are you using Dual-Core or Single-Core RAM?

pmcnano · #**417** 07-10-2008, 08:05 PM

I guess you refer to dual channel, yea im using 2x2gb dual channel ddr 333mhz ECC memory.

With the overclock on my system the ram is setup to 420mhz, and i dont have that much issues compared with non overclocked rig.

naquaada · #**418** 07-10-2008, 08:11 PM

Hm, I can't overclock my RAM, computer won't start then. But my RAM is 400 MHz without overclocking.

if you want to OC RAM sometimes its possible to higher your ram voltage!
some mobos have special settings for that

naquaada · #**420** 07-10-2008, 10:54 PM

Yes, I have settings for that. But I don't try it, my system runs fine like it is now. Always say: NTARS
