TLB...TLB...TLB....![]()
I've had two Phenom 9500's since Nov.26
One crunching at stock speeds full load-> NO TLB CRASHES
The other one been overclocked
been running at 2772Mhz since Dec.27
TLB fix disabled
running games,benchies and crunching-> NO TLB CRASHES
If I had TLB crashing I don't my Phenom would have made it to 32nd spot on Riesel Sieve Boinc for daily RAC in less then a week

Does it matter if there is TLB bug on Phenom... Answer NO
The bug is very critical for servers.

Thank you for those links, this is the first time i see the bug in action.
The guy who answerd is working for AMD according to his sig, so it seems to be no BS this time.
I could not make the bug occure with xen and differen guest osses all running prime95 or other benchmarks.
It would be interesting what software he ran.
It is not as easy as such. The guess is its due to hot spots. Thats also one reason it could be safe at under 2.4Ghz. So Its abit like OC and chips. Random picks. Maybe only 5% of all chips have this bug at stock speed. And with an increased chance with higher frequency.
if it was a fixed bug so to say. I am pretty sure AMD would have caught it in their QA process.
We have a few people here with 0 bugs, and we have an example of a person in WCG forum where it crashes.

There is a detailed description of the TLB-thing at LostCircuit here.
I dont want to say the bug does not exist, but i experienced it is pretty hard to trigger it.
Thx, gona try to trigger the bug with WCG. Do you remeber when the crash was reported in the WCG forum.
According to LostCircuit the bug can only occure with hardware enabled virtualisation. What did the person at WCG use?

He just ran WCG and it crashed a few times.
Also i think you misunderstood my post. Its not hard to trigger as such. It just depends on your luck of CPU. If there is a hot thermal spot or not and if so, at what frequencies. I do not believe it s a virtualization only bug. Its a pretty lame excuse. Also you would just have the BIOS setting where you disable or enable virtualization to enable or disable the fix aswell. I call it a smoke screen![]()

Best answer I can give you is it not crashing under full load at all. The stock one is running Boinc 24/7. The OC'ed one, the only time it's not running Boinc is when I'm gaming or benchin'
True. Especially if your running virtualization on that Server
The thread title is about Phenoms not Barcelonas.
I don't think you'll see too many using a Phenom for virtualized mission critical servers.
Is TLB bug on Phenom going to crash Average Joes(sinlge OS Windows machine) multithreaded game...No
The TLB bug doesn't prevent you from overclocking but overclocking should increase your chances of tripping the bug
Can anybody show me that somebody actually tripped the TLB bug on Phenom(not Bacelona) running a single OS. Please, because I want to try too.
The crashing on WCG probably has more to do with ram compatibility.
