I am trying to talk myself into buying a really decent pair of ram. I want extreme timings for my ram. Im getting the P5W DH Deluxe mobo with the thermaltake armor w/ 25cm side fan. The sticks im thinkin of getting are these: <a href="http://www.newegg.com/Product/Product.asp?item=N82E16820231077" target="_blank">http://www.newegg.com/Product/Produc...82E16820231077</a> Will they help the speed of the computer compaired to there 300$$ counterparts? If I overclock my processor can i go passed 1066 speed? The reason i ask is because the mobo says it accepts 800/1066 speed. Will this be a problem?

Well... the superpi record is still held by the DDR2 800 $300 kit. So I guess that will do just fine <img src="/images/smilies/smile.gif" border="0" alt="" title="Smile" class="inlineimg" /><br />
<br />
Do remember that the 1:1 divider is at DDR2 533 speeds (stock), thus you'll need an FSP of 533MHz to hit DDR2 1066 speeds on a 1:1 divider. You can of course set the RAM on a divider advantageous to the RAM (thus on DDR2 667 at stock or so). The DDR2 800 kit should be able to hit close or a bit over DDR2 1066 speeds.... <br />
<br />
You have an E6600, and with a multi of 9 I don't expect your FSB to go that high. I'd save the money.

Nah!, that's too much $$$. <br />
<br />
Just like Chozart says, get the $300 G.Skill DDR2 800 kit and you're be doing DDR2 1000 with a 4-4-4-8 @ 2.2v. <br />
<br />
But if you have the cash for them? Go for it.

So what kind of peformance would i get out of the 2? How would it affect games?

Performance would be awesome in either case. Personally, I would be surprised to see a whole lot of difference between the two kits. With an E6600, you can run the RAM at DDR2 667 speeds anyways (which is faster than the CPU). I don't think any increase in RAM speed relative to the CPU will improve performance (RAM can only handle CPU instructions as fast as the CPU delivers them).<br />
<br />
Imagine: you get your CPU to run at 3.6 GHz (thus and FSB of 400MHz). Your RAM will run at DDR2 667 speed (stock) and the effective speed will be 400/266 x 667 = DDR2 1003 speeds. As Nasgul says from experience, that's a speed attainable with the DDR2 800 kit.

Chozart where are u getting the 667? my ram (stock) runs at 800.

Yeah, but you want to overclock! Thus, running at 800 stock won't do when yuo overclock. Let's say, again, an FSB of 400MHz (CPU=3.6GHz). If you set your RAM at DDR2 800 speeds, it'll run effectively at 400/266 x 800 = DDR 1200 speeds. Too fast for DDR2 800. Thus, like with any high-speed RAM, you knock the speed at stock down (i.e. put the RAM on a divider). <br />
<br />
Not again, the 1:1 divider for Core 2 Duo is DDR2 533 speeds.

What divider would i use to get 667 speeds?

That would be a 5:6 divider (in favor of the RAM). 1:1 is DDR2 533, thus 5:6 will result in 533/5x6 = DDR2 667 speeds (a little rounding)<br />
<br />
Generally, you can simply set the RAM to DDR2 667 speeds in your BIOS (depends on the motherboard/BIOS how it exactly works)

</div>I'm a bit confused here 'bout "correct" RAM for C2D.<br />
A thread somewhere left the impression, that where AMD generally benefits most from the timings as opposed to frequency, it's the other way around, generally, with Intel. <br />
The question is if there's enough benefit from the 8800 Dominator RAM 4-4-4-12-2T at 2.4 (from corsair sales pitch), to legitimize thier price over e.g. Dominator PC2-6400 at CL3. <br />
It's on the P5W64-WS which seems pretty <a href="http://valid.x86-secret.com/show_oc?id=126287" target="_blank">capable</a> (<- with a Mach2) but all this divider stuff says that there's no reason for chosing the MHz impressive Dominator PC2-8800 over lower cas PC2-6400?

As Nasgul said, the $315 G.Skills will overclock to DDR2 1000 with a 4-4-4-8 @ 2.2v.<br />
<br />
To me, it's not worth to spend the extra $$$ on the Dominators.<br />
<br />
Also, I don't see an PC2 8800 Dominator on Newegg... it's either PC2 8500 or PC2 8888

I would agree with Chozart...I have the PC-8888 Dominators with an E6600 on water and I can do just as much with my DDR2800 that I can with the Dominators....I only got the Dominators because I wanted to see how far I could push an E6300...It is here that you are going to need all the Speed that you can get...<br />
<br />
PS - Get the G'Skills or Get some Corsair DDR2800 C4's...They are both about the same amount of money....$300 vs. $610...Hmmmm <br />
<br />
Hope this helps

I have GSkill DDR21000 4445 timing native RAM with my 6600. It's currently OC'd to 1.1 GHZ at 5455 timing. The computer is a screamer. I'm a believer in GSkill.

I was thinkin of getting those sticks Frankenpc but i decided its not worth the money when i could just oc. They do have better timings though. Chozart, with that cpu cooler the Zalman i think it is, what temps are u getting with the E6600? What temps are u getting when the E6600 is overclocked?

The Zalman works fine for me. At 3.51GHz, I hit about 59C - 60C at load.<br><br>
This cooler is highly dependent on a good airflow in the case. If you have good airflow, it's a good cooler. However, coolers with a more powerful (120mm) fan perform better in cases where airflow is not that good (think Tuniq Tower, the Noctua, Scythe Infinity and such)

hehe, my bad, yes it's PC2-8888 I mean <img alt="" class="inlineimg" src="/images/smilies/wink.gif" style="border:0px solid;" title="Wink"><br><br>
So a pair of "G.Skill 2GB DDR2 GA PC2-6400 (2x1GB) CAS3 Dual Channel Kit (F2-6400CL3D-2GBGA) (MY-016-GS) " 3-4-3-8 owns the 1111MHz, but only 5-5-5-12, PC2-8888? And at a 120£ lower price <img alt="" class="inlineimg" src="/images/smilies/smile.gif" style="border:0px solid;" title="Smile"> (@ overclockers.co.uk)<br>
Sweet .. I might even end up with enough dough in the budget for MachII/VC-LS. Again ... sweet <img alt="" class="inlineimg" src="/images/smilies/biggrin.gif" style="border:0px solid;" title="Big Grin"><br>
But I don't see why all the fuzz around the Dominators when even the PC2-8500 arent too impressive on the timings, and I was under the impression that pure MHz was all the Intels really needed. They got a fancy cooling feature, but that about it? Even the Dominator PC2-6400 3-4-3-9 are more (a little) expensive than those G.Skill.<br>
[edit]sorry, my bad ... what I called "Dominator PC2-6400" are <i>not</i> Dominators but 'regular'[/edit]

I am not saying that the DDR2 800 G.Skills own the DDR2 1111 Dominators. I am saying it's not worth spending double the money for not too much increase in bandwidth.

My plan is to hit 426.4fsb and change the multi to 8 so my ram will reach 1066 and my proc will hit 3.4ghz. Will this be possible with the Gskill 6400's? My ram will be divided by 5:6.

Not sure about 1066, but Nasgul is running 1000 on them, which is plenty fast<br><br>
Personally, I would put on 1:1, get a bit higher FSB, and thus run yuor CPU a bit faster.... and RAM at like DDR2 900. (FSB = 450, multi 8, RAM 1:1 @ DDR2 900). That'll give you 3.6GHz on the CPU, and a good speed on the RAM

What if i increase the voltage and fan cool the sticks? Will it be possible then?
