Overclocking a P35C-DS3R

[Ararat]

Hi, I purchased a Gigabyte P35C-DS3R motherboard a few days ago, and much to my chagrin (amidst my excitement about overclocking), found that it doesn't have a 1:1 memory divider. I have an E6300, along with DDR2-800 Memory (Samsung). Now, with this 400MHz memory, I should have plenty of headroom to overclock my 266 MHz CPU, right? WRONG!! The stupid piece of crap (which aparently automatically adjusts the divider to suit the FSB, yeah right) tried to run my DDR2-800 at '1200' (presumably 600) MHz. That's ok, I can do it myself, right? Nope, the only option in the BIOS is a '2.5 multiplier' (doesn't include synchronous speeds, and yet it includes the oh-so-useful muliplier of 4). Is there a way around this? What if I had bought DDR2-533, overclock by default? Presumably it would run at stock by SPD, but anyone with such memory would be unable to modify these settings.

How can I get the memory to run synchronously with the CPU, so that I can overclock? I am using BIOS revision F2 (latest atm), and it seems to me that it would be SO EASY for Gigabyte to have put that option onto these boards, but instead they have shot us in the foot. A helpful poster in the motherboard forum has told me that his DS3Pro has the option for 1:1, does anyone know which of gigabytes P35 boards let me do it? Should I take it back to the shop and buy a Pro? (I would consider this a downgrade, as while I see DDR3 as something I may not use, I could never afford 2 fast gfx cards, and frankly would prefer the extra PCI slot).

The best oc I have got atm is 333MHz (2.33GHz CPU), with my RAM running at '833', and thus overclocked, I'm not sure I should push my RAM further, and would like options. A nice trick would be greatly appreciated. Thanks.

I am considering this board, but will holdoff on it until this problem is rectified. Like Ararat..I feel the fix should be EASY for Gigabyte to get on the ball and do the right thing for their customers. How about it Gigabyte..let's get with it..you do want to sell this board..RiiGHT ?

"You need to hit Ctrl+F1 to reveal all the overclocking/RAM settings"

I believe you do this in the main BIOS menu.

M.i.T
Cas Speed
Mem Multiplier
I cannot Find it either
I paid Extra for this Memory
OCZ

It's there, you don't need to press ctrl+f1 (unless you want to access the timings), the dividers are there in basic mode. The thing that stopped me from seeing it is that they are out of order. The 1:1 divider (called a 2x multiplier by the BIOS) is a ways down list.
It goes like this:

Auto
2.50
3.00
2.00 <-- here it is
2.40
3.33
4.0+

So ronach, you don't have to worry about the board, the options are there, and you should be able to oc it ok. If you want, I'll post on how far I pushed my 6300.

Here is my thread in the overclocking forum for those who want to see:

the 2.00 = 1:1 so if you have your fsb running at lets say 325 fsb then using 2.00 will give your ram a speed of 650.....325x2.40=780, 325x2.50=812 and so on....so i have my e4300 stock is 9x200 running at 9x325 i set the ram 3.00=975 cuz my pc6400 is rated to do 800 but with a lil more volt 2.0 it can run higher with out any problems
