Overclocking on 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.

Set your memory multiplier(spd) to manual(in bios).Now choose 2.0.This will set ram to 667mhz.When you raise the cpu host frequency(fsb) your ram will follow.

So:7x400=[email protected] memory divider=800mhz on ram.If you need to change ram timings,place bar on M.I.T in bios.Push ctrl and f1 at same time.Reenter M.I.T and you will see ram timings.

At this time,the latest bios is F4G Beta.Can be found at Gigabyte web site.

I'm having hardware failure or Prime95 has nothing but hate for me. Comp will run great as long and someones playing with it, but don't leave it or she'll get ****ed and crash.

I have:
GA-P35C-DS3R (rev. 1.x) | Core 2 Duo E6600
OCZ 2GB DDR2 1066 (PC2 8500) Micron D7 Chip
spec's on the memory says it runs at 2.3v and if the MB default setting is 1.8v (Gigabyte tech support) then I increased my memory voltage [0.5+].

and I'm having the same problem. I should nvr bought the MB, too many buttons (M.I.T)

I don't follow the formula...(7x400=[email protected] memory divider=800mhz on ram) can't seem to rap my pea around it.

I'm looking for a LIL' help, just tell me what to set and to what to set it at in the BIOS and I can.
