Can somebody explain to me in full the relationship between the two?
I was going to buy some 1150Mhz RAM with a Q6600, but then was told to just get 6400.

Just tell me everything about CPU's, Overclocking, an RAM that I will ever need to know :D
 
Install all of the hardware -> enter bios -> load default settings -> save settings :p

The 6400 ram will allow you to overclock your cpu to 3.6Ghz before the ram itself has to be overclocked. The ram you were looking at would be used to attain very high overclocks, whilst running @ 1:1.

There are lots of threads that provide very descriptive guides to overclocking etc with various boards, that will help you understand all the settings etc.

The popular P35 motherboards include (as they clock very well, and generally very feature rich):-

Asus P5K-E/Premium
Abit IP35/Pro
Gigabyte one that ocuk doesn't seem to stock anymore .... can't remember
DFI Lan Party DK P35-T2RS
MSI P35 Neo2-FR

Hope that helps ;)

erm... Hard to describe

Basically as you rasie the front side bus (F.S.B) if will begin overclocking your ram.

If your ram is running @ default 1150Mhz then it will be overclocking from 1150Mhz (meaning the high its gets, the more volts and slacker timings to be stable)

However if you use a memory divider then you will be running your ram @ a slower speed. The benfit of this is that you can then overclock your processor bringing your ram speed back to its original speed (i.e. overclocked processor and ram @ 1150 keeping the timings tight).

Also by lowering the divider you can overclock your processor further becasue the ram won't be limiting your overclock.

I found that hard to try and explain - I'm sure someone will manange a much better job/correct me :p
 
I'll have another attempt.;)

1:1 means the memory is running at the same speed as the fsb eg 400Mhz fsb = memory running at 400Mhz (so with ddr2 memory it means 800Mhz)

So with a Q6600 and you are running at 9 x 400 = 3.6Ghz and your memory is set to 1:1 then your memory will run at 400Mhz = 800Mhz effective.

Yes you then can run your 1150Mhz memory at 1150Mhz by setting the fsb/memory ratio to say 2:3 which would then overclock your memory to 1200 however round number ratios work quickest such as 1:1 and 1:2 plus if you have to slacken your timings to get 1200Mhz running stable then you may lose more than you gain.

There is a balance between tight memory timings and fast speed eg memory running at 900 @ 4-4-4-12 may perform faster in games/benchmarks than memory running at 1000 @5-5-5-15. You just test and find which is quicker with your overclock. Higher speed of memory in general is quicker than faster timings with Intel cpus but there is a point where that doesn't work. Google ddr2 ram reviews where you will find ram running at 1300Mhz which is slower than 1150Mhz ram due to the slacker timings.

And finally what Happy said about the ram you listed used for high overclocks running at 1:1 is just rubbish. I have yet to see a motherboard capable of runnign at a fsb of 575 stable unless you are using a multiplier of 2x to have the cpu running at 1.15Ghz as well.
 
Ahh k Groovy.
I think I got it now.

With that ram you saw in the other post and a way ott air cooling system, I was thinking...

How bout 8x500 on Q6600 and 1000Mhz DDR2. Acheivable?

P.S. I was even thinking of sticking a couple of Delta 120mm's in an antec 1200 and maybe one on a Themalright Ultra 120.

1000Mhz ram is okay but you have two problems there.

1. mobos which run at 500FSB stable are few and far between. Google mobo reviews and you will see what I mean.

2. Q6600 which run at 4Ghz are also few and far between. With the voltage normally required for that, custom water cooled or better is the only normal way to get that. Look at the Q6600 overclocking database. I think there are only 3 running at 4Ghz and their temps are very, very toasty and thier voltages scary.

So I think you are been too ambitious. 8 x 450 = 3.6Ghz with your memory either running at 1:1 and 900 with very tight timings or probably even 5:6 ratio and then running at 1080Mhz is a acheivable target.

You might then get yourself up to maybe 8 x 475 = 3.8Ghz which is what I can do on mine.

haha, thanks for the info.
I think I went a bit wide-eyed then.
This is far too exciting for me. Im still stuck on a 2.8Ghz Pentium D with a gig of 533Mhz at 4-4-12-16.

You are hardly going to notice any difference then :p;)
