i wouldnt be here if it was that easy haha the frequency list only goes up to 800
edit: ill try what the screenshot says, gimme a sec

Have you updated your bios?

Double Data Rate RAM, DDR. This means that the listed frequency of the RAM is double what it actually is due to being able to read and write at the same time.
Example: DDR2 800 RAM is really running at 400MHz, but because it can read and write data in one clock cycle instead of one at a time, it's listed as 800MHz. Essentially, it's just double.

Setting the RAM to DDR2 533 makes the RAM run at 533Mhz. DDR2 1066 is really a problem with naming, as that's what it's rated for overclocked. Meaning the RAM is guaranteed to run at 1066MHz, overclocked from the standard 800MHz. Thats why you pay a premium for the 1066 RAM, its the cream of the crop. Of course you can usually take it higher then that, but 1066MHz is what the manufacturer is guaranteeing that memory will run at.

If the board does support natively up to 1066, which Yellow's post says it does, you may need the latest BIOS for it.

well the list expands when i change stuff to manual but then i have to know what to change everything else to such as timing and voltage

On the RAM itself, there is usually a sticker which lists the timings, voltage, etc.

This is when the manufacturer's specs come into play, let's see.

1066MHz DDR2
EPP 5-5-5-15
(CAS-TRCD-TRP-TRAS)
Available in 2GB (2x1024MB) Dual Channel Kits
Unbuffered
OCZ Lifetime Warranty
2.1 - 2.3 Volts 240 Pin DIMM

Copied from OCZ's website here: OCZ Technology | Products | Memory | OCZ DDR2 PC2-8500 Reaper HPC Edition

So I would set the voltages to 2.2v, which most of us here agree is the safe limit for DDR2 RAM when overclocking. Any higher and you risk damage. The timings should be 5-5-5-15 2T, which is normal for running RAM at 1066MHz

Since the specs goes up to 2.3v, I think he should set it to 2.3v first, then see if he can scale back. EVP goes up to 2.35 without losing warranty, if you're going extreme :P

i tried those settings and its the same for every other time i try, it just restarts and doesnt work with it, im beginning to loose confidence =( perhaps ill just be stuck with 800mhz

first of all: could you please make a sig or just list all the hardware specs in your computer so we can help you?

for hints what should be in the sig look at some members signatures.

i did but its not showing?
