I've read all the guides but I still can't overclock my A64.

Ive read all the A64 guides and Ive been trying to overclock with my new hardware but my computer randomly resets/BSODs/freezes everytime I do ANYTHING.

Specs:
DFI NF3 Ultra-D Bios 824
Venice 3200+ E3 w/ SI-120 + Panaflo L1A
Patriot 2x512 PC3200 XBLK TCCD (Brainpower)
Seagate 160GB SATA
ATI X850XT
Windows XP SP2

Everything at stock seems stable (not sure if it' stable with memory @ 1T though). I've set AGP freq to 68Mhz to lock it, and my SATA HDD is also on port 4 so it should be locked too. Voltages are all on default.

Anyways, first thing is to find max HTT and max RAM correct? For HTT, I set multiplier to 6, DRAM to 100 (take RAM out of equation), set RAM @ 1T, then proceed to increase HTT. I increased HTT thru ClockGen in Windows. I hit up to 320HTT and more (can't remember) and computer seemed fine, but when I restart and try loading in 250HTT in bios, it wont even POST or go into Windows. This means ClockGen is useless doesn't it? No point telling me I can run 320HTT if I can't even boot up with 320HTT. So far finding HTT's been unsuccessful.

Next I try to find max RAM. Multi's at default, which is 10, DRAM is set on Auto, RAM is @ default timings which is 2-2-2-5 BUT I used 1T instead of 2T (1T is default). Again, I locked HDD + AGP. I go into Windows and increase ClockGen again, it freezes after I hit 225. I reboot and try to set that in bios and run Memtest for one round but again it doesnt POST.

Someone please help me :)

this is xtreme overclocking here not xtreme helping ;)
I think someone should move this to AMD section...

My suggestions for bios:
HTT Multi: 3x
don't now about the RAM but if it's TCCD should handle 1:1
CPU Vcore: 1.5V
HTT: 265MHZ
Timings: 2.5-3-3-6-3-2-2-2 (top to bottom in A64 tweaker) 7ns/5ns (2 values (bank interleave and another), maybe they are 6/4ns or 7/5.5ns in the right row of a64 )

It's already in AMD not Xtreme Overclocking.........

Try using the BIOS instead of Clockgen.

i keep confusing myself because i read too many guides with different instructions, so im just gonna start simple, step by step here....
im gonna start first by finding MAX HTT..

tell me if these steps are correct:

1.Set CPU Multiplier at 6
2.Set LDT Multiplier at 3
3.Set Vcore at 1.55v, Vdd at 1.85v
4.Set Vdimm at 2.7v, RAM @ 1:4, RAM @ 2-2-5-2-1T
5.Then slowly increase HTT by 10 every 20 minutes and test for stability.

Please tell me this is correct and I will proceed to do this :)

It seems correct but take a look here.

What I did when o/c is trying first without any overvolt , lets all at stock volt first and find your max at stock.

Don't know what's your rev , but mine was rev1 and overvolted like hell 0.1v on vcore and vdimm (cpuz and bios reported 1.5v when it was 1.6v on DMM)

what about stop spamming around? it was moved, I saw this topic before it was moved and suggested to move it - k?

I think it is not that good to lower the CPU multi that much....there is no need to underclock it that much....9x300 was running on every winchester or venice I tried!
Vcore is too high for the clocks you're running! I would use 9x 250 on stock volts and go up from this point the way you suggested.
And try to keep your ram running @~200MHZ to high dividers are useless because you won't run them in all day use when you want good performance.

Try 705 BIOS.
Set CPU Multi @ 9.
Set VC @ Default.
Increase Vdd to 1.75 or 1.85 when going over ~290HTT.
Set RAM @ 2T.
133 RAM divider (2:3).
Leave all RAM settings @ Auto (except 2T and divider). (You could set CAS, RAS to CAS, RAS, Tras @ 2-2-2-5).
Increase VC by using "Default +.x" instead of the 1.xxx settings.
