Help a confused noob?

Hey
I'm trying to overclock my computer and I'm a little confused about some of the stuff.

First, is the Athlon X2 3800 multiplier locked? i ask this because i realized this morning when i was doing the increase ram speed, do memtest86, increase ram speed, do memtest86+ etc. that even when i have it sayin that my computer is at a 6x multiplier i was still getting a 10x multiplier in memtest86+. I don't know if this is a problem with memtest and if cpu-z will show differently (i had to get to school so i couldn't check) or if its a problem with my board (ASRock 939Dual-SATA2) since i've been concerned on how good the board's bios is recently...

[edit]
I just noticed a thread in OCWorkbench ASRock section and i think i finally understand these settings but I'm a bit confused, so the CPU-NB Speed is actually a mutliplier? How does that work? what number correlates with what? so far i gather somethin glike 1000 = 5x and 600 = 3x, would that mean you just divide it by 200 to get the multiplier?

[edit: disregard the following]
Second, I'm want to keep the HTT thing below 1000, i know from zebo's great thread, but i have absolutely no clue where my bios puts the LDT. I've looked through everything and the only thing i can find is CPU-NB Speed/aperture and similarly for NB-SB. are these related to the HTT speed or is it some other setting that my motherboard doesn't have (shout out to budget stuff...)

Specs:
Athlon X2 3800
ASRock 939Dual-Sata2
OCZ Plat 2x1gb

The Athlon 64's are mult locked for higher mults, not lower ones, the X2 3800 is locked at 10, but can do 9, 8, etc ... Ideally you can test your max FSB speed, your memory speed, and your CPU speed.
Example, I run my board at 250Mhz fsb, 4 X HTT mult, 1:1 memory, 10X cpu mult, so I get
2500 Mhz, 1000Mhz HTT, 500 Mhz DDR Memory ...

I have tested the FSB upto 300Mhz with memory at 5:6, with a HTT mult of 3, but chose 250 to keep memory and CPU at optimal speeds, ie the cpu doesn't like 2700mhz (9 X 300).
That result was 2.7Ghz, 498 Mhz DDR Memory, 900Mhz HTT.

Your Htt speed is simply your FSB X the HTT multiplier. 800 - 1000 is a suitable range. Now I'm not sure whether or not you can adjust that on your board.

Thanks Uhtrinity,
Does anyone then have a problem running A64 X2's on my board, ASRock 939Dual-SATA2, at lower multipliers because right now according to CPU-Z my bios fails...
