I'd like to run a 8400 at 4.0Ghz (445 X 9) and am wondering which memory would be able to do the job

  

http://www.newegg.com/Product/Prod [...] 6820146726
with increased clock and voltage

 

OR

 

http://www.newegg.com/Product/Prod [...] 6820146755
clocked down with (hopefully) slightly better timings

 

no need to worry about the other components, they can take anything that's thrown at them

 

*Edit* links actually work now

I'd go with the PC8000, it's a safer bet since the PC6400 aren't guarunteed to run at nearly 900mhz.

I thought so... any idea if I'll be able to trim down the timmings at all?

What are the stock timings? I didn't see it in the link.

Either way generally with a underclocked module you "should" be able to tighten the timings. Again no Guarantee.

You will get tighter timings then if you were using the 6400, as the 6400 would have to be loosened up to hit 900mhz (if it even could).

the timing on the 8000 are 5-5-5-12 (I chose the memory cuz the last number was lower) and it's the fastest I could find (other than another memory from mushkin that cost twice as much for 2 1Gig sticks)

http://www.newegg.com/Product/Prod [...] 6820146114
with 4-5-4-11 but giving it's half the capacity at twice the price it'd be a waste

Hmm you should be able to lower this when you underclock it. Even if it's just a little. Something like 5-4-4-12, or if your lucky 4-4-4-12. You won't know till you try:)

As I mention in the other thread you asked, I'd just look around on the web for an hour and read a bit. There are plenty of sticks 0f 800Mhz RAM that can do 4-4-4-12. That means you at least get 850ish from almost all of them. And some will reach 900, unfortunately its the older ones that OC better! believe it or not.

But if you pay attention you'll notice something with the new sticks, the 800 Mhz 4-4-4-12 stuff by most major brands is the same as the 1000/1066 junk at 5-5-5-15. You'll note that they always seem to have the same "special" functions and voltages.

BUT... that means that almost all of the 4-4-4-12 can run at 1000+ if YOU do the same thing they did, and loosen the timings.

Lame but true. They appear to pick through the new stuff and get the good ones and label them a higher model, or "factory overclocked edition" And the many names for that.

It appears to hold true for processors as well.

Waaaaaahhhhhh!

yeah, I went on one. Thats why my name fits the personality!

Oh, but at least you have a chance of hitting 4-4-4-12. The 1066 junk doesnt like to underclock and tighten timing cycles. I have 4 x 2 gig GSkill 1066 and it wont hit 4-4-4-15 until about 700 mhz.

So at least you HAVE a chance at hitting the better timings at 900 with the DDR2 800 Mhz Sticks!

so the "ideal" thing to do would be to find a place that sells both, buy both, test which is better and return the other?

Thats a bit questionable, but sure, if you dont mind the moral implications, go for it!

Hell, I took a flash drive with me to 3 office depots and checked the VIDs of their processors and worked them for the display model on my good 1.2000 VID q6600!!

So what the hell. And like I said, you have 10 x the chance of getting some 800 Mhz Ram to hit 900 than 5-5-5-15 junk 1000/1066 LOWERING to 4-4-4-15 @ 900Mhz.
