Hi,
I'm new to tom's hardware and new to building and overclocking PCs.
I built a new system in Dec 09 and I'm really pleased with it, but I know with a bit of tuning and overclocking I can make it somewhat better!
This is my system...
i7 860
asus p7p55d motherboard
corsair CMD4GX3M2A1600C8 4GB 1600MHz 2x 2GB RAM kit
nvidia 8600GT 1024MB
2x 500GB Western Digital caviar green 32MB Cache
Win 7 x64 Ultimate Edition
I plan to upgrade my graphics card and double my RAM in the near future.
I want to tune up my system now to get the most out of it. I have been trying to do as much reseach on overclocking before i start so I have as good an idea of what I am doing as possible, however I still have a lot of questions that haven't been answered in any of the articles I have read so I decided it's time to start asking people in the forums!
Okay first things first... I want to use my computer mostly for computing, not games. I mostly use it for a heavy amount of photoshop, Illustrator and web browsing and also some coding of websites and word processing. Also in a year or so I expect I may well get into video editing.
What I have so far learnt is that the type of computing I do is very memory intensive and so therefore I should try to configure my system with this in mind. I have been told that I should try and get the most out of the potential my RAM has to offer.
These are the stats for my RAM...
Fig 1)
Fig 2)
Fig 3)
it is 1600 MHz RAM but I have a couple of queries about it..
1) what is the difference between Real Clock (beign 800MHz) and Effective Clock (being 1600MHz)? is that normal to have a real clock that is half the effective clock? if I only had 400MHz RAM would it's real clock be 200MHz?
2) in Fig 3 it says 'DRAM Slot #1 2GB (DDR3-1333 DDR3 SDRAM)' does this mean that my memory is actually only running at 1333MHz? I read that the maximum speed supported by the intergrated memory controller on the i7 860 processor is 1333. Does this mean that 1333 is the maximum i will ever get out of my memory? Figs 1 & 2 show the memory to be running at 1600MHz (800MHz) so what is the truth? What speed is it actually running at?
Fig 2 shows that my DRAM:FSB ratio is 6:1. This is what I have been told I need to tweek. I've been told I need to get the ratio as close to 1:1 as possible so that there is no redundancy in the speed of my RAM.
As I understand it, anything where the ratio is higher than 1:1 on the DRAM side means there is redundancy in the RAM and it is simply not getting used and so it would acctually make no difference to have RAM with a lower speed as long as you didn't go below a ratio of 1:1. Is that statement correct? can you corroborate this for me? If there is a point to having fast RAM when you don't have a 1:1 DRAM:FSB ratio then please could you explain it too me!
So to get a better DRAM:FSB ratio I hear I need to raise my Base Clock speed. In all of the tutorials for overclocking my processor or or one of the processors in one of the i7 or i5 families the Base Clock has been raised to around 190 - 200 MHz. Raising my BClock to 200MHz would give me a DRAM:FSB ratio of 4:1. That sounds like a good improovement but it's still a long way from the 1:1 ratio I desire.
In none of the overclocking tutorials I have read does it mention anything about why they have settled on this Base Clock. So why have they decided this is the best place to stop raising the BClock and instead raise the multiplyer? They have given no reasoning in any of the tutorials. Is there a danger in raising the BClock higher? or Is it possible to have a really high BClock and a low multiplier? Such as a BClock of 266MHz and a multiplier of just 14 to give a Core Clock speed of around 3.8GHz? A BClock of 266 would give me a DRAM:FSB ratio of 3:1 which is better still.
So what I need to know really is:- Is there a danger in having a very high Base Clock speed?
If there is a danger what is the nature of this danger? Is having a high Base Clock dangerous full stop?
Or is it only dangerous if I want a high Core Clock speed as well ( say 4GHz). I would be happy with only overclocking my Core Clock to 3.4GHZ or 3.8GHz if it means I can get faster memory and overall better system performance.
Or is there no reason why they chose this value to stop at and it was purely arbitrary that they chose 200MHz to stop overclocking the base clock at?
here are a couple more Figs to give you any extra info that may help you help me...

Thank you very much for taking the time to read all of my article.
Any help that you can give is much appreciated!
