Well i read everywhere and have a pretty good ideas about overclocking but i just can't stablize my system. i've got

650 Watts of thermaltake PSU
DFI Lanparty nF4 ut ultra-d
AMD athlon 64 X2 3800+
Corsair xms 1gb pc 3200 ram
8800 GTS 640 mb
Stock cooler, (temp. never went higher than 42 C even under heavy load)

I tried FSB 200 to 250 with 5 intervals. increased some DRAM voltage and LTD voltage AND chipset voltage with .10 intervals. Couldn't find a way to increase cpu voltage. some1 told me it's risky increasing voltage without knowing anything. so i'm here. Currently it's back to factory settings. but can any1 tell me how i can overclock it. and any good settings?
 
You cant just overclock everything at once (cpu, memory and motherboard) and expect it to be stable.

First off, what bios do you have, some shipping bios'es for this mobo are fine, some arent. 6/23/05 which came on mine stock would be fine, but ive seen 3/10(?)'s which wont be. What type of memory do you have, if you have TCCD chips, then that wont be your limiting factor.

This is explained in many FAQ's but I mite as well restate it.

First thing you want to do when overclocking your system is to drop down your memory divider to 1:2 (DDR200) or something low, and drop your LDT multiplier to 3x. What I would do is start raising your fsb to overclock your cpu, little by little intill you get to a good stopping point (2.4 ghz isn't that big of a stretch for your x2), you mite need to raise your vcore as well at this point. Then get into windows and prime95 your cpu (inplace FFT) (two iterations of prime95), for about 10-15 miniutes, if it doesn't fail then you know you can go higher, if it does, then you mite just need to raise your vcore more.

Anyways you keep doing that intill your cpu wont go faster or your heatsink becomes the limiting factor on the overclock.

Then to overclock your memory, go to 1:1 memory divider, keep the LDT at 3x, and drop your cpu multiplier to something low (6x sounds good), and start going up in frequency with your memory, to test its stability (to get a good idea) I say use memtest (test #5) thru 5 passes, if you can do 5 passes of test 5 w/o errors, then its a good (not definite) indicator that your memory is still stable, keep going up in 2-3mhz increments, increasing the memory timings as needed (other topics which discuss this) intill you get to a maximum number, (you mite be able to increase your mem voltages by .05 or .1v if its TCCD, but tccd doesn't respond well to voltage increases.

I don't think your mobo will be a limiting factor for you overclock (unless your going above 300 mhz fsb), but it mite be helpful to test it anyways.

A successful overclock would be to combine the highest cpu overclock with the highest mem overclock + get the FSB as high as possible.

I currently am at 2805 mhz cpu, 280mhz fsb, 3xLDT multiplier, 233(ish)mhz memory, 10x cpu multiplier, DDR333 memory divider. I also increased the fsb (HTT) and LDT frequency's by .1v. increasing these voltages is trivial to how it helps increase stability, but It hasn't hurt yet.

I'm sure theres more which I haven't added but alot of this is stuff that is better learned if you spend the time searching forums (xtremesystems.org forums in preticular).
 
I see a couple problems here beyond your methodology.

XMS doesn't play well with an ultra-d in my experience. Mine was very finicky, I did eventually get it where I wanted it, but it had spots in between stock and my final overclock where the mem was just NOT stable at all. And as a note, my ultra-d probably had 6-8 different CPU's and at least 10 sets of ram in it over the course of it's life. That was by far the most finicky of the bunch.

Second, Ultra-d's love good clean power, I question your PSU choice. BUT it SHOULD be fine.
 
well thank you so much for helping. i got it overclocked to 2.4 Ghz Memory running 200 Mhz.

was stable in in 2.5 but when try to get the memory to go little higher it just doesn't work. So I got the FSB to 240 and memory 5/6 and it was stable. it was stable through 1 hrs of torture test by prime95 and some memory test. i couldn't get the memory to over a little. and i din't want the cpu to any higher than 2.6 becasue i got stock coolers. but i'm happy with having it at 2.4 and 200 memory. Thanks for helping me out.
