I havent much experience of overclocking with a a64 so am hoping someone on this forum could help me here.

My gear is - Dual core A64 3800+ using a freezer 64 cooler.

G.Skill 2GB DDR ZX PC3200 (2x1GB) CAS2 Dual Channel Kit (F1-3200PHU2-2GBZX) (MY-007-GS) CAS Latency : 2-3-2-5

Asrock dual sata 2 motherboard (bios 1.60)

I would like to overclock it to 4400 speeds, so 2.2ghz can someone tell me how to do this please? I'm not sure about htt and things. Would I be able to get this speed on the default voltage?

Temps at the mo are 40c full and case is 33c

Any help welcome. :)
 
2.2ghz should be easy to get to. I have the same cpu and mobo and got mine to 2.5ghz on default volts with the stock cooler.

First set the ram to run at a 133mhz divider. Then set the overclock mode to cpu, pci-e, Async. Just increase the cpu frequency to 220 for 2.2ghz. Go into the chipset options and set the cpu NB link speed to 800mhz if the freq is under 250 and set it to 600mhz if it's over 250.
Keep increasing the the frequency until it's unstable.
When the system is unstable increase the volts. The max volts on this board without the mod is 1.4V which is safe.
Check the temp and try not to let it get higher than 55c.
 
Ok I'm sorry my brain isnt working today, I never noticed the overclocking guide on this page. I'll have a good read and see if I can start overcloking my x2 3800. :)

Just posted before I saw your reply, thanks very much for the info mate. I'll try it and see how it goes, big big thanks. :)
 
The overclocking guide needs updating if u ask me, its good but ive read it a few times and ive always ended up still posting, it doesnt talk about deviders for one.

The best thing to do is to just search google for a review of the motherboard u have, ther is usually an overclocking bit of the review. I did this when i wanted to overclock, it helped me understand specifically how my board worked, so now my 3700 clawhammer is at 2.8 :D

I got water though :rolleyes:
 
Yeh for AMD these days thers loads of things to consider and adjust that doesnt even get a mention in the guide.

Theres running a devider, adjusting the ht ratio, the HTT, multiplier etc. Theres a lot more to it these days.
 
I have applyed the settings you told me Lee87, and I now have a nice little overclock with no extra heat or very little.. check it out...

Delighted, thanks mate. :D

I'm now running at 4200/4400+ speeds now right?

No problem, as said it will run at 4200+ speeds, the extra cache is the same as 200mhz so you need it at 2.4ghz for 4400+ speeds.

Did you overclock it any higher, you should be able to get it to at least 2.4ghz maybe 2.5ghz on stock volts
 
Havent treid any more overclocks just yet as I had to do a reformat of windows. I will though in the future, maybe try for 2.4.. that would be very nice. :)
 
Excellent thanks,

Seems very stable @ 2.2 as I would have thought it would be. Gonna try for 2.5 that would be amazing, I just need to change the cpu frequency and nothing else right?
 
As long as you have changed the settings I mentioned earlier then thats all you have to do. If it unstable when you do this change the cpu voltage to 1.4V.

edit: for 2.5ghz set the CPU-NB Link Speed to 600mhz
