I have the following set up:

====================================
CPU:AMD 3200+ Venice

MEM: OCZ 2GB (2 x 1GB) 184-Pin DDR SDRAM Unbuffered DDR 400 (PC 3200) Dual Channel Platinum

MoBo: DFI LANPARTY UT nF4 SLI-DR Expert Socket 939 NVIDIA nForce4 SLI ATX AMD

CPU-Fan: ZALMAN CNPS7000B-AlCu LED 2 Ball Blue LED Light Cooling Fan/Heatsink

Vcard: eVGA 256-P2-N563-AX Geforce 7900GT CO 256MB 256-bit GDDR3 PCI Express x16
=====================================

I did some tests and found out the following:

#1.-set CPU multi to 6 or 7, this will take CPU out of equation
-set memory to SPD and 100, this will take memory out of equation
-Increase HTT/FSB up until you fail to boot or there abouts, back down 5%, (HTT * 0.95), this is your max safe HTT.

= 253.65 @ 95%

#2. Max Chip capable
- Set multiplier to it's maxium
-Set vcore to 1.6 -1.65 for 130nm chips, 1.50-1.55 for 90nm chips
-Set mem to SPD and 100, this will take memory out of equation
-starting with HTT 200 raise in about 5Mhz increments up to boards max
-At the point it starts failing within that 5 min time period, back down 5%, (CPU MHZ * 0.95), thats your max CPU speed, now test prime again at 95% for 12 hour for stable.

=240? **Here i set the Mult to x10 (chips maximum) and lowered the vcore to 1.52. I put the memory to 100mhz (1:2 i believe). 240 ran fine but i only ran it up to this speed since it was safe and i wanted safe spot for now.**

#3. Memory MAX
-Set CPUs multi to 6-7, again to take it out of equation.
-Raise HTT up to boards max or until you start failing memtest86 test 5 and 6 http://www.memtest86.com/
-When you start failing memtest86 test 5 and 6, back down 5%, (HTT * 0.95), thats your max MEM speed.

= ? **I ran these tests last night for about 5 hours and nothing failed at 2-3-2-5 and i was happy with it but i have no clue how does this give me a "max MEM speed." **

Now; coming from this website: http://math.gogar.com/athlon64.cgi
It asks for 5 parameters:

-CPU = 2670 was the max that i found stable while using SuperPie-32M
-RAM = No clue what to enter here
-HT = No clue
-HTT/FSB = 253 from the previous tests? I'm also not sure about this.
-Multi = 10x

Using those values and leaving the rest to default it gives me some options like:

HTT : 253
CPU : 10 x 253 = 2530
Memory: 17:24,141,DDR283 = 180.71 (DDR361)
Hypertransport: 4 x 253 = 1012
score: 28.4235

-------------------------------------------------------------------
Questions:

1) How do i find Memory Max speed?
2) How do i find Max Chip Capable Speed? and how is this different from test #1 on the above tests??
3) Right now i'm running at stock speeds: 2ghz, 1:1 200mhz ram, x10 multi, htt/fsb multi auto (i've read i need to lower this to x4).
-3a) Evertyhing else constant, i try to raise my CPU from 200 to even 201, i can't load to windows. (This is the value before the x10 multiplier [stock 200x10=2000mhz cpu speed])
-3b) Move CPU speed up to 240x10=2400mhz cpu speed and lowering my memory speed to 100mhz, i'm able to load into windows and the CPU is overclocked but i believe i'm cheating myself as my memory is dragging behind? (i drew this conclusion from test #1, this takes the memory out of the CPU test equations)

Here are some images from CPU-Z in case i missed any details:

===============================================
I know this is long but i've been trying to figure out what i'm doing wrong for over 2 days now. ANY help would be very appreciated. I've read about 5 manuals on how to overclock and i'm still unable to.

Thanks again guys and i'm sorry for the newbiness. :(

Wow-that is long! In the BIOS genie utility:

Set the CPU multi as high as it goes
Get the RAM running as close to stock speed as possible (your CPU might not like dividers below 3:4 - but use the lowest you can)
Get the Hypertransport running below 1000MHZ (usually a x3 divider)
Push the chipset voltage up to 1.6 (from default 1.4, I think)
Instead of setting the CPU voltage to 1.6 directly, set it to 1.45 x 110% (this option is directly under the VCore setting)

Now raise the FSB straight up to 250 and superpi

Keep raising the FSB until you become unstable/too hot

Because your mem is PC 3200, it will start to crash at anything more than about 10% overclocked (max 220mhz, if you're lucky) - memory crashes in games are usually followed by frozen picture and stuttering sound - with a CPU crash you will either see some wierd stuff happening or the screen will go black.

At the lowest divider I can use (3:4) your RAM will be working at stock speed of 200mhz at an FSB of 266. So, you should have a bit of wiggle room with that low divider. If your CPU locks out at 250-55, you can use a higher mem divider

Let me know how it goes

I dont have a 3:4 option

100 = 1/2
120 = 3/5
133 = 2/3
140 = 7/10
166 = 5/6
180 = 9/10
200 = 1/1

ok - 250 FSB with 5/6 divider will be ok, RAM at 208mhz

If your CPU will go higher than 250FSB drop down to the 7/10 divider if you can - then the FSB should be able to reach 280-285 without the RAM flaking out, as long as the CPU can take it - My opteron wont go lower than 7/10, but my CPU craps out above 311FSB anyway, so its not a major issue for my PC4000 @ 259mhz

Has changing the voltage options helped at all?

*Just setting your memory to SPD and picking a low divider will not necessarily take your memory "out of the equation". DFI is kind of notorious for having aggressive default memory timings, and they have about a billion things you can adjust.* Also, your max HTT is not 253 with that board, it just doesn't stop that low with any DFI NF4 board. Most likely one of those aggressive memory timings messed you up.

I would focus first on your memory... here's a nice guide on DFI's memory options http://www.dfi-street.com/forum/showthread.php?t=11397. So, set your CPU multi to 6x, up your Vmem to 2.7/2.8, change your HTT multi to 3x, increase the fsb voltage by .1 or so. Use the above guide to set some relaxed timings manually, there are A LOT to change, so print out the guide. Once you relax the timings, start increasing the HTT (1:1 ratio with memory). It sounds like you did 240 without problems, so start there. Keep increasing by 5-10mhz and then test with memtest until you get to where it starts erroring. Back down a little (4-5 MHz) until memtest stops erroring. Now you know your max memory speed. You can fiddle with all the timing parameters later.

I gotta go, but will check back a little later.

So THIS is how i get my MAX memory speed?

BTW, thanks for the replies guys. I'll try both suggestions now and see what's up.
