I had decided to upgrade my PC and can really use your help in trying to figure out what parts I would need to reach 4Ghz OC from this PC!
I currently have ABS Tagan BZ 800W PSU, 9800GTX, 3 WD640AAKS HDD (two in raid 0) and Cosmos S case that I will be keeping. I live in the US and newegg had always done a good job delivering my parts in the past, but if other websites have the parts cheaper I dont mind ordering from them. I currently have Two 24" monitors. Im not in a rush ordering these parts. I will be using raid 0 & if a MOBO has SLI & CrossFire enable that would be a plus, I don't plan on using it right now (maybe in the future) but if a certain MOBO is a great for OC but is 3 way SLI crossfire then it doesn't make a difference to me. For now my goal is to get to 4Ghz 24/7 stable. Online Gaming is the primary role of this PC. I don't have a budget but im not made out of money ether if u know what I mean. If an extra $100 is something that will be a big help in getting it to 4Ghz then I will get it.
Its been about a year since I did any extensive research on computer parts, but from lasts night search here is what I have in mind so far. I am 99% sure that I want to go with the i7 920 CPU. I heard this processor are very OC friendly, and a lot of people were able to get to 4.0Ghz with good air cooling. The hardest part for me is to select a good MOBO that will handle a 4.0Ghz OC and good RAM to go with it.
Someone told me that these are the Top Tier Overclockers:
EVGA X58 Classified
ASUS Rampage II Extreme X58
Gigabyte X58 EXTREME (can't find it on newegg anymore) All of these boards are about $375-$400 Do I really need one of these boards to get to 4.0Ghz? How hard will it be for me, someone who doesn't really know a lot about OC to get to 4ghz with other MOBO’s?
The other MOBO’s that I was told are also good are ASUS P6T or P6T Deluxe, Gigabyte GA-EX58-UD4P or UD5, EVGA X58 3X SLI.
From what I hear in order for me to get to 4Ghz I need at least 1600Mhz RAM. I never liked to settle for “at least” so would it be fair to say that 1800+Mhz would be perfect for me? Or will 1600Mhz will be more than enough for me to get to 4Ghz?
well most x58 boards will reach 3.8ghz+ stable the main thing will be cooling the cpu at that speed and forget ram faster then 1600 only the 965 an 975 can use higher then 1600 to its full potential this will do fine http://www.newegg.com/Product/Product.aspx?Item=N82E168... what you looking for in i7 ram is voltage 1.65 or lower a low cas latency and then you look at the speed for instance 1333 cas latency 7 ram will perform as well as 2000 ram at cas latency 10
And there are 3 different RAM's I'm having hard time deciding what to get... What what I hear ASUS recommends not going over 1.6v for ram on the P62, but a lot of people have 1.65v RAM and are doing fine.
Not sure what you are asking for... is it any CPU that can go to 4 Ghz on stock air cooling or is it a quad core than can OC? I think you'll have a problem getting any quad core to go 4 Ghz on stock cooling. You're asking 4 cores to push themselves toi the limits to squeeze out 50% or more past their manufacturer rated capacity and all this on stock cooling??
Will there be a noticeable difference in boots and games with 7-7-7-20 compared to 9-9-9-24 ? And in terms of getting the i7 to 4Ghz + will this speed difference matter? I really don't know much about RAM as you can see. By the way the 1600Mhz is good enough to get me to 4Ghz but what about if I decided to try and push it just a bit more, 4.2Ghz - 4.5Ghz will the 1600Ghz still be able to take it or will the 1800ghz or 2000Ghz will do the job much better?
The numbers "7-7-7-20" and "9-9-9-24" indicates: 1. CAS latency 2. needed clock cycles and 3. "Ship out" Time cycles.
Which means that a RAM with better "Timings" will take less time (Milliseconds) to let's say ship out the data which then the speed is determined by the memory FSB freq.
So basically 2 memories A. 1600MHz, 7-7-7-20 1tb B. 1866MHz, 9-9-9-24 2tb the A memory would win, Why??
Because look at it that way: Memory A takes 7 cycles to finish a CPU's command let's say that's 0.7 milliseconds (just let's say!) while it takes the result info (also let's say!) 0.7ms while memory B takes 9 cycles to finish the same command that's 0.9ms while it takes it 0.5ms to deliver the info to target devices.
So A= 0.7+0.7=1.4ms while B=0.9+0.5=1.4 !!!! Well that's weird but those aren't benchmarks nor theoretic calculation it's just what i can recall now and what i understand but ALWAYS the memory with (Significantly) better timings would beat the memory with (Significantly) higher memory freq. .
Hope I helped some, I am not an expert but thought i could benefit you this time.
Please if there's anything wrong let me know as I just wrote a summery of what I know and understand from this subject.
@Psycho Sykes, this did infect helped me understand ram timing a bit. Thanks.
So looking at the two links that I provided above, is it worth the extra $$$ to be getting one over the other? I mean like you sad in theory the lower timing would be better, but this will be an OC PC to 4Ghz so taking this in to account, what you think?
Well, As far as I know OC'ing the RAM FreQ. is far easier than lowering the timings so if you get the 1600MHz 7-7-7-20 1tb you may easily get it to let's say ... 1733MHz 7-8-7-20(or 24) 1 or 2 tb (Hopefully not 2!!, or it doesn't worth OC'ing the RAM).

Why you need to get 4ghz? your saying the i7 920 benefits 4ghz more than 3.6ghz?
"By the way the 1600Mhz is good enough to get me to 4Ghz but what about if I decided to try and push it just a bit more, 4.2Ghz - 4.5Ghz will the 1600Ghz still be able to take it or will the 1800ghz or 2000Ghz will do the job much better? "
LOLLL, you can't get to 4.2ghz - 4.5ghz without watercooling, unless you get a lucky sample of the chip and doesnt burn at 4.2ghz which is next to impossible.
just get 1333 ram with tight timings or 1600 ram with slightly higher timings, the performance will be around the same though, so save some money with the 1333.
