Water cooling is a bit above me.  I haven't ever set it up so wouldn't know.

Any overclocking can shorten the life of your PC parts it deosnt matter how cool they are kept.  The cpu will be doing more than its designed to do and will more than likely have more voltage going through it than standard.

I believe when you do rig up watercooling you have to do a leak test, for obvious reasons.  Water and electrics IMO ar a no no.  I just air cool, I run 50C max at full load in summer, down to about 45C now its gettin cooler. Its all to do with airflow.

If you are going to overclock you really need some benchmark programs though.  Sometimes overclocking can cause throttling or smothing you do make your system run outta synch, so even though you have high MHz etc your system is running like a heap of junk.

For example My system as below scored 24000 or somthin in 3dMark01.

I overclocked my CPU to 2600MHz so a lot faster than it is  to do this though I had to run the ram out of synch.  Thus my bench score went down to just under 20000!  Big numbers dont always mean good results and you need somthing that will show you what tweeks you are making make an improvement.

The 6800 cards when overclocked to much also throttle.  My card @450/1200 scored 13457 which is pretty good.

I set it to 465/1200 and it passed all tests required.  Benched it and it scored 12200 or there abouts.  The card was throttling itself 

Just a few things to take into consideration when overclocking.

Futuremark as well I think.  Same people made it that made 3dMark03 and 3dMark05.

That was with 3dMark01SE

I think this loooks nice!

Thats the same stuff I got.  I run Corsair XMS PC3200 2x512 sticks in my PC.  I managed to tighten the timings a bit though over standard.

No good if you want to overclock though!  You wont be able to raise the HTT much at all with that ram.  Its only my ram holding me back at the moment.  You shoulda realised this if your planning to overclock so much though 

bout this?? http://www.newegg.com/app/ViewProductDesc.asp?description=20-144-114&depa=0

can i over clock that well?

Thanks:)

Ok so PC 4000 is the best? Ya got any suggestions of PC 4000 1gig dual channel ram? I will worry about clocking the ram once i get it. I just want ram thant can overclock alot and thats really fast.

To get lower FPS wou want memory with a high bandwidth and Low Latency, i.e. tight timings.  A lot of the good quality ram is capable of achieveing tight timings.

Be careful when purchasing ram as for exampl OCZ do more than one type! i.e. performance ram, ehanced bandwith ram etc etc

Ideally you want ram you dont have to overclock. So you get ram with a speed that matches the FSB of what you will be overclocking too.

I think you should go look into overclocking a bit more especially with regards as to what your mobo is capable of and any probs you may encounter.  For the speeds you are trying to achieve you should kinda have a good idea of what you are doing otherwise your gonna end up with all kinds of unstability problems.

As for the ram, I cannot reccomend any.  You will have to make your own decision on that one.  I haven't purchased any rams with higer speed than PC3200 so cannot quote whether its good or not.  It would be a shame though you spend more money on high speed ram and at the end of it you struggle to overclock and end up with you system running at a low FSB as your ram will be wasted then.

Myself when I buy ram will buy OCZ PC3700 Enhanced Bandwidth Ram.  This only 466MHz but it has tight timings and my Multiplyer is locked one higher than yours at 11 so 11*233  (Half of 466) = 2563MHz which I would be happy with.
