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. :(

1) the way it said to - what happened is the mobo max is lower than the memory max according to what you reported. See if your mobo has the higher RAM ratios enabled and maybe you can use them.
2) what do you mean by chip capable? The chipset? CPU? memory chip? They are all chips, so I'm not sure what you're asking.
3) That's right - lower it to x4 until you break 250mhz, then go to x3. You can play with it to find exactly where you have to lower it or play it safe and never let the result go over 1000 (200x5).
3a) Try setting the htt multi to 4 for this and see.
3b) Lower the memory speed to 166 in this case - the RAM would be slowing you down otherwise.

I don't use those calculator things - but you can if you want to. In the HT you would put the htt multi (x5, x4, etc.). Hmmm... How can you have a CPU at 2670 with a mobo max of 253 and a max CPU multiplier of 10? If you got it to 2670 on that mobo, then the mobo has a max of 267... I'm confused. :?

What I would use myself is the 'brute force' approach (probably a bad way to say it...) and start clocking up:

Set everything to stock - RAM @ 200, HTT @ 200, HT Multi @ x5, CPU mult @ x10. Set the HT Multi to x4 and turn up the clock a few. If it won't boot, loosen the RAM timings & keep going. If you hit a wall before 250, you know its the RAM (based on your earlier reports). Set the RAM speed to 166 and keep turning up the clock. At 250 set the HT Multi to 3 and keep climbing. You should hit 267 at that point. If you want to keep going, do so, or call it a success and stop.

Mike.
