is 1066 really worth it?

I'm getting a q6600 and planning on oc'ing to 3.0 - 3.4ghz. I'm sort of stuck on which ram to buy. I was going to go with 4gb (2x2) patriot viper ddr2 1066, 54.99AR. Then I saw a deal on Corsair, same thing except ddr2 800 24.99AR. Is it worth double the price to get 1066, or will 800 work fine for my overclocking plans?
 
Dont know, what ARE your OCing plans ?

8 x 400 for 3.2GHz puts 800MHz ram right on spec and you can likely get another 25MHz of FSB before having to loosen the timings with a nice 1:1 ratio topping out at around 3.3GHz with a respectable rock solid OC.

or

see if 9 x 366 works and the lower FSB lets the NB strap tighten up for a better Trd but you will be underclocking 800MHz ram and the next lowerst mulitplier will probably OC the 800MHz ram significantly requiring loose timings but maybe not just have to test and see.

Or go with 1066 give up the synchronous setup and basicall try the above with higher memory mulitpliers or stay with 1:1 which will underclock the ram, by a lot, but take it completely out of the picture as far as casuing issues while you OC the cpu.

Or really push it and see if you can get to 9 x 400 for 3.6GHz and run 1:1 with 800MHz memory or 2.5:1 with the 1066

or

Find that no mater what you get there is no memory multiplier setting that will let you maximize FSB but still run you memory with tight timings without underclocking it.

The 800 will work fine. The 1066 will give you more flexability but is not really needed. Frankly it depends on what board you are going to use and its avaialble settings for NB straps and memory multipliers and how stable it is at non 1:1 memory ratios.

So its all about how hard you want to push the 6600, From my experience speeds over 3.2GHz really dont make that big a difference in any apps, games included. (I am sure there are some exceptions out there) and you should be easily able to get to 3.3GHz 1:1 with tight timings with even a poor OCing 6600 and 800MHz ram. If you happen to get a good one and have a top of the line heatsink, good case cooling, strong PSU, do the board prep etc. etc. and intend to go for 3.6GHz go with the 1066 stuff just for the flexiabilty and ease when setting up the system. You can set the memory multiplier to 1:1 and would have to run the FSB up to over 500MHz, which aint gonna happen, before the memory specs are exceeded. That lets you just worry about what the cpu can do and after that is sorted out you go back and play with memory mulitpliers and timings to get what you can out of the memory. With the 800MHz stuff you might have to juggle both systems if the cpu does not like 9x settings ( and some boards and cpus dont).


or

I have it all wrong.
 
The best way to overclock is to find the highest fsb your board can do reliably with the RAM you have, and then find the highest Mhz your CPU can do reliably.

If you want an easier time of finding the highest FSB the motherboard can do, the faster RAM will help.

Also, running the RAM over 1:1 doesn't help on Intel setups before i7.

Ideally you want close to the highest FSB your board can run as well as having the CPU close to the highest Mhz it can do reliably.

3.6Ghz at 9x400 is a bit slower than 3.6Ghz at 8x450.
