I have AMD Athlon64 x2 4200+ 2,2Ghz, MSI K9N nF570 SLI-2F, A-DATA DDR2 2x1GB DDR800 5-5-5-18. I put AC Freezer 64 Pro and Overlock my CPU to 2596.. FSB set 236 x 11 = 2596 set CPU Voltage to 1350V, default is ~1320. Memory settings set Memclock Value 667 Mhz next set 5-5-5-18 manual and add plus 5V (voltage). If I set Memclock Value 800 Mhz my PC crash and I get error with wrong overlock. But with 667 Mhz works fine ! :) I have max 50 CPU/CORE temps. I want do much more overlock about ~3Ghz or 2,8Ghz. But if I set FSB 238 PC crash. Imposible do more OC ? What I must set ?

 
3Ghz is too much for AMD cpu's. You should aim around 2.7-2.8Ghz max.

Try to set FSB to 250Mhz. This will give you 2750Mhz. You'll need some juice on vcore for that, i think +0.15v should be enough. Don't forget to drop HTT multi to 4x. Finally set your memory speed to 533Mhz. If you're able to boot you can try 667Mhz next. Good luck.
 
Sorry, i don't remember where it was exactly but it was like 200Mhz, 400Mhz, 800Mhz... So you have to select 800Mhz there.
 
Ok man !!! I found it ! Thank you very much ! :p I OC'ed 2,7Ghz stable, if I set to 2,8ghz I get error from Orthos. ;/

HT Link It's normal ? I set to 800Mhz
 
Yes, nice to hear you did it. You have to keep HT Link speed around 1000Mhz. When you set it 800Mhz it means Bus Speed x 4. So it's 246x8 in your case. What's your memory speed now?
 
That's ok but you might wanna try one step above than your current memory speed. If it's 533Mhz now try 667Mhz. That should give you CPU/6 ratio and 450Mhz memory speed. I think your memory can handle this with a little bit of added voltage.
 
Oh I don't say you, my CPU is 2,7ghz 246 x 11 = 2706 and I set default extra cpu voltage and set to max. voltage to 1.400 V. And now my cpu use 1.350-1.370 V. Set HT to 800Mhz. Memory use 667 MHz 1.95V 5.0-5-5-18.
 
honestly, if you wanna try to see what your cpu can do and then tweak memory/HTT bus later on, then drop that HTT to 600 or even 400mhz (3x/2x) and drop the ram to ddr400 speeds first.

the average for 4200+ am2 is about 2.6-2.7ghz. the brisbanes are ranging 2.9-3.1ghz
 
Hey, how do you guys overclock without increasing the Vcore past 1.4volts? The only way I can keep my X2 4600+ at 2.7GHz is if I put the voltage up to 1.45. And anything past 2.7, it won't be stable at any voltage. Or is it b/c I'm using a 939 cpu?

hmm..nm, for some reason cpu-z is showing 1.424V even though it's set at 1.45V. Random.
 
We don't have magic wands, not all the cpus overclock the same. I was using a 3500+ cpu and it wasn't overclocking as much as my current cpu.
