Abit IP35-E with DDR2 1066? Basic OC question.

I'm putting together a new rig and have already purchased about 3/4 of my components, including 4 GB (4 x 1GB) of Corsair DDR2 Dominator 1066 memory. The last 3 things I have to get are MOBO, Video Card, and CPU.

I know I'm going to go with an Intel 8400, and some form of Nvidia 8800GT. Now I just need to pick a good MOBO.

I don't plan to run RAID, won't do SLI, don't need Firewire, nor do I really need more than 4 SATA ports, but I do want to overclock my 8400 to either 3.6 GHz or 4.0 Ghz.

I understand the relationship between the clock multiplier, CPU FSB, and memory multiplier. Using a clock multiplier or 9, a memory multiplier of 2X, and CPU FSB of 400/445 I should be able to OC the CPU to 3.6GHz/4.0 Ghz (with some additional cooling on the high end). This would have my memory running at 800 Mhz or 890 Mhz.

What I don't understand is how/if a MOBO that says it only supports DDR2 800, can be pushed past this to 890 Mhz.

Is that just considered a RAM overclock, or will it just not work?

Will I run into any problems if I do this with my RAM being too fast?

Can anyone help me understand this better?

I'd love to be able to pick up this MOBO for $89 at Newegg, but if it's going to limit me in any way, don't mind spending a bit more to make sure things work well.

Thanks for the help!

"Support" of RAM means it can run that RAM speed at default speeds.

So you could run your E8400 @ its default 3 GHz with RAM @ DDR2-800 (instead of say only DDR2-667).

That in no way means you cannot overclock your E8400 to 4 GHz, or are prevented from getting that RAM to DDR2-1100 speeds :D

You understand things fine...in this case, don't worry about what the motherboard "supports", as only those running stock would care about those things.

Thanks for the quick reply n7. Sounds like this MOBO could work for me.

In general are overclock limitations when it comes to MOBOs with respect to the MOBO's FSB/voltage?

One other question -

Does anyone know if the IP3-E will run 4 sticks of 1GB ram? I was also looking at the ASUS P5KE (on the high end) and had read it has trouble with having all 4 DIMM slots filled.

Thanks again!

yes, it can.
2x 2Gb is usually a better configuration for mobos than 4x1Gb though.

Thanks all.

I just placed my order with Newegg, and also decided to send back a kit of DDR2 2x1GB memory. From what I've read, combining 2 different kits (especially when versions are different) is just asking for trouble.

Now I just need to pick out what version 8800 vid card I want, and wait for Newegg to get Intel 8400s back in stock.
