At 2.5Ghz 1.552v during SP2004 my cpu temp is ~38C. Core Temp Beta program shows that cores is about at 55-63C. Are thes cores' temperatures normal for X2 cpu?
 
Those core temps seem accurate if you are at 1.5v+ vcore. That 38c is probably just your ambient temp around your cpu. Trust the core temp temperatures over your motherboard reading. But, I guess you could call them normal for overclocking, although they are getting up there a little high. I'm guessing you are on air, not water.

Open 2 instances of SP2004 and set one to each core.. then let it run for 5 hours or so and let us know your core temps. At about the same vcore and 3.0ghz, I'm significantly lower than that being water-cooled.. but if you are on air, expect those temps to be higher like yours are. I'd back off a little bit. I'm sure you can get it that fast with a much lower vcore, but you failed to let us know what your hardware specs are, what all your other settings are in your bios, ram type, mobo, etc.
 
I'm using DFI LanParty nF4 Ultra-D and corsair twinX2048-3200C2PT.
FSB:RAM divider is set to 5:4 and HTT multiplier x4. SP2004 is not stable at 1.536 and it fails after 1.1/2 hour. At 1.552v SP2004 is running fine.
 
Set your HT to 3x. That usually helps a lot with stability when overclocking.
I guess you are still on air though? What processor?
HTT? Multiplier?
 
X2 3800+ sc 939 with AC Freezer 64 Pro.
FSB 250Mhz and multiplier x10.
 
Before you start the CPU stress test in SP2004, you'll see the option for CPU 0 or CPU 1 in that little drop menu. Right now yours is probably set to "any". Open one program of SP2004, set it to CPU 0. Open another instance of the program, and set it to CPU 1. Then start both of them running. I think the new beta of SP2004 supports both cores in one program though.

I'll try... What core temp is dangerious for K8 core?

depends on voltage.. and how long you plan on keeping your cpu.

as a general rule of thumb, every 10c increase is roughly 1/2 the lifespan. typically, cpus are designed to handle 70c without a problem at stock voltage... i've brought my clawhammer over 100c and it still works today (actually typing on it ;))
 
Well.. I'm on water cooling, and I really don't want mine to go over 1.55v. I want my temps to stay cool and my processor to last. If you need to be raising voltages much higher to achieve a little bit more of an overclock, it isn't worth it and you hit your processor's limit. Not all processors can overclock the same, even though they might be the same brand and model. For example, someone's 4600+ might go to 3ghz, where another persons's might only go to 2.7ghz. Different motherboards and ram can factor in as well.
 
In Athlon 64 overclocking guide I've found that it is recommended to keep K8 temps <55C. Is it about cpu temp or core?
 
2.4Ghz/ 1.488v/ while gaming cpu temp ~38 and core temp <55C.
2.5Ghz/ 1.568v/ while gaming cpuu temp ~40 and core temp 55-60C.
At these settings SP2004 is stable >10hours.
At 2.6Ghz 1.568v I can play games, but SP2004 fails immediately.
What to do you think about my OC results?
 
Speedfan 4.29 shows the cpu temp and the core temp. Someone told me that cpu temp is around cpu and core temp is cpu core temp.

That's correct most of the time.

There aren't a lot of programs out there that actually monitor the on-die thermal diode, and instead use a thermal diode located in or around the CPU socket on most motherboards.

I believe what you are seeing in Speedfan is:

CPU Temp = Motherboard based thermal diode
Core Temp = On die thermal diode

The on die temp will typically read quite a bit higher than the motherboard diode...
 
In Hardforum ( Athlon 64 OC guide) it's recommended to have Athlons' 64 temps <55C. 55C is for core temp or not?

I'm pretty sure that was written with the motherboard diode in mind, but you'd have to check with whoever wrote it.

From what I understand you should ideally not go past the TCaseMax for your processor - you can find this out through the AMD spec sheets or some programs like "Core Temp.exe".
