x2 3800 @ 2.5Ghz

post #1 of 10
Thread Starter 
Hey,

So I gave it another try at 2.5Ghz on air.
FSB 250Mhz
HTT 4x
DDR2 533
Vcore on bios 1.38v
Vcore on SpeedFan 1.25
Vcore on CPU-Z 1.28

Max temp 50ºC


http://valid.x86-secret.com/show_oc?id=210933

I ran the OCCT torture test for 30 minutes, it said it was stable but I was monitoring temperatures with SpeedFan and Temp 3 went up to 70ºC, and then when it finished, it went back to 2ºC.... what could possibly be that temp?

With those varations, I'd say your temps are no being reported accurately!

Might want to try out CoreTemp to monitor your temps. I've got my X2 3800+ all the way up to 2.70Ghz, but everything kept saying I was running 90 degrees C! I went with CoreTemp...still running really hot (about 80), but it seems much more accurate. I've now gotta figure out how to "lap" my CPU and cooler, hoping that'll do the trick. By the way, you should be able to hit higher than 2.5 if you try. Mess with your RAM timings and speeds some. I haven't ran DDR2 yet, so I couldn't tell you what to set it at...I'm still on Socket 939. Anyway, hope this helps some.

Thanks. CoreTemp says Core#0 is around 21ºC and Core #1 at 23ºC, while speedfan shows 33ºC...

I prefer to guide myself with Speedfan.

Edit: how can I get 1:1 CPU RAM ratio?

21 and 23 degrees idle! Overclock the hell out of that thing! Mine idles at 45-50 C stock! CoreTemp for me has ALWAYS been a more accurate temp reader. It has something to do with the sensor the programs use I think. I don't know for sure...but Speedfan will usually give you a higher temp than what you're actually running.

With that being said...even 33*C with speedfan, that's still a great idle temp. Overclock it! Lol.

RAM @ 1:1
That would require RAM that can match the CPUs bus speed!

From time to time the computer freezes... don't know why. I've lowered the RAM frequencies, and it froze again. I thought it could be the PCIe clock, so I locked it at 100Mhz and set back the ram to 533.

I'll try to run Orthos, to get a more accurate stability test.

Edit: I have the ram @ CPU/8 right now. with the Intel Processors, the Ram must be equals to the FSB right?... so with AMD cpus its different?

Some RAM is funny with certain dividers!
Also, as another member points out...
Try the TRFC @ 105 or 127...
With AMD systems, there are a few advanced timings that can drive one nuts because of there effect on instability!
