Im looking at a computer build and for the most part it will be using a e6400 and I intend to OC it to about 3GHz, nothing extream.

What I am curious about is the different "speeds" of ram on the market.

A example is im looking on newegg.com and I can either get OC extream performance in 2 x 1GB sticks or "normal" 2 x 2gb sticks for the same cost.

But even then its not that simple, ill show ya.

Here are two 4gb kits that im looking at:

G.SKILL 4GB(2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model F2-6400CL6D-4GBMQ - Retail

Cas Latency: 6
Heat Spreader: Yes
Labor: Lifetime
Parts: Lifetime
Timing: 6-6-6-18
Voltage: 1.8V - 1.9V
Price: $399.99
AND

G.SKILL 4GB(2 x 2GB) 240-Pin DDR2 SDRAM DDR2 667 (PC2 5300) Dual Channel Kit Desktop Memory Model F2-5300CL5D-4GBMQ - Retail

Cas Latency: 5
Heat Spreader: Yes
Labor: Lifetime
Parts: Lifetime
Timing: 5-5-5-15
Voltage: 1.8V - 1.9V
Price: $399.99

Now the 1st one is a faster speed (6400 vs 5300), but the slower one has a lower latency, which I assume is better. So which is it?


The 2GB kit im looking at is this:

OCZ FlexXLC Edition 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model OCZ2FX800C42GK - Retail
Cas Latency: 4
Features: OCZ FlexXLC (Xtreme Liquid Convention) heatsink
Heat Spreader: Yes
Labor: Lifetime
Parts: Lifetime
Timing: 4-4-4-15
Voltage: 2.0V
Price: $223.99

Its also a 6400 but the CAS is 4.


I dont have alot of extream overclocking in mine, just as much as I can get with air cooled. I want to go watercooled, but that may be 8-12 months after the inital build.

So what is better? My main uses for my system is City of Heroes/Villains, DVD encoding/burning, Command and Couquer 2 and Supream Command when they come out. I dont really play games like Half-life or 1st person shooters, at least not in a way that most extream gamers play.

If I can get 30-40 FPS, im happy. I dont need 90-120 FPS.

As far as the G.Skill 4GB kits, they are very likely the same sets, just with a different SPD. Take the DDR2-800 set, drop it to DDR2-667, and you should be able to run it at 5-5-5-15 also. Same with the DDR2-667....most likely will run DDR2-800 @ 6-6-6-18. Notice all the numbers are the same(voltage, model #..even price..except speed, ). The reason for the higher latency's, is because the bigger the DIMM, the harder it is to get tight timings with it. i.e..a 2x512MB kit will run tighter timings than a 2x1GB kit, which in turn runs tighter timings than a 2x2GB kit. The OCZ kit should work well. If you only plan on 3GHz with your E6400, thats's 375FSB(therefore 375MHz RAM speed@1:1). Running the OCZ @375, you may be able to snug up some timings...say 4-4-4-12, or maybe better(especially if you put a little more voltage to them. GL :)

Thanks for the info, but does the CAS really make that much of a difference.

Since I dont plan on OCing the ram, would the 4GB kit work just as well as the 2GB kit. Its kinda the Price vs Performance issue personaly.

I would perfer to have 4 gigs since I run alot of stuff when im gaming, but not if its going to hinder the performance by 10% or more.

The slightly looser timings of the 4GB kit won't make "that much" difference...maybe a couple %. Some apps will benefit from the extra RAM, but not many... and not many games either. 4GB will be more important with VISTA, and/or 64bit OS. Using 4GB in XP...only 3-3.25GB will be available to the OS, so it seems like somewhat of a waste, under most circumstances. You have to decide whether the added cost of 4GB is worth it at this point in time. Eventually, it will become "the standard", but that may be 1-3 years down the line.. Will 4GB be cheaper then, or now? I'm thinking it will be cheaper then (1GB DIMMs were quite expensive when they first debuted, but are standard now, 2GB DIMMs will likely follow that same trend). Just some food for thought. GL :)
