OVerclocking AM2 3800+ X2

Radio91P

Hey,

I am trying to overclock my 3800+ X2 and seem to have run into some problems. I have had no problems overclocking my 939, but can't get the hang of the AM2. I talked to a guy that clocked his X2 3800+ to 2.7. Supposively the same chip as the FX-62. If any of you have had some experience please give me a few tips. I am still novice at overclocking, so all advice is welcomed.

Thanks,

hmmm try upping the vcore a lil...and the ramcore a lil just to give some more stability, its all trial and error in my experience

The first thing you'll want to do is use a lower RAM divider (i.e. the 667 or lower). Also, once you start passing a reference clock of 230MHz, you should drop the HTT/LDT multiplier to 4x (800MHz). Just increase it a few steps at a time until you see some instability. At that point, you should begin increasing the vcore.

A few questions:
1) What brand/model/spec ram are you using in this rig?
2) What brand/model mainboard are you using?

Most of the steps in the guide I wrote for 939/754 still apply to AM2 (see link in my signature). I hope to update it soon to include AM2 overclocking.

Best of luck!

Hey Lemon,

Thanks for the tips, your guide is how I even have an inckling of what I am doing, so thanks.

Asus M2NE
2x512kb DDR2 800 Mushkin extreme w/ stock timings of 4.4.3.12
AMD Athlon X2 3800+
Antec Truepower 550W

What is the most accurate temp guage. Using both coretemp as well as PCProbe. Probe states 46 under load and coretemp states 38-40 under load. Which is best for accurate readings?

Thanks,

Also bios revision 0203

Hey Lemon, this is where I am at right now!

FSB=301
Multiplier=9
Vcore=1.47
3x htt
w/DDR2 800 divided to 533 at 4.4.3.12. 2T

Which leaves me at a final speed of 2709.

idle running at 44-45, load 55 with crap cooler(according to pcprobe)

I have the new Zalman CNPS9500 AM2 cooler coming which will hopefully keep this a lot cooler. Going for the FX-62 speeds for $150 bones,

ahhahahahahahhaha

Later
by the way, it's stable for over one hour on Prime95

Awesome! Congrats on an awesome overclock so far!

What was holding you back? was it the RAM divider? I'm happy to see your ASUS board was able to handle a 300MHz reference clock. Hopefully your new Zalman will lower your temps enough for you to push further a bit. If you can keep the temps under 50'C, you should have some ideal conditions to push ahead (and increase the vcore a bit more).

Best of luck! let us know where you end up

Thanks Lemon,

I think part of the problem was that I forgot to change the htt multiplier from 4 to 3. In addition, my motherboard would automatically multiply by 10 instead of the 9 that I had it set on. This would cause the board to fail POST everyother time. When in windows this bugger is stable as a rock. Haven't had any more problems now though. Don't know if it was just a glitch or what.

Thanks,
