Which PC2-6400 Memory, does it matter?

Hey,

I'm looking to buy 4GB memory for a new PC (from Scan, so I was hoping to get the memory from them too) 2x either:

2GB (2x1GB) CorsairTwinX XMS2, DDR2 PC2-6400 (800), 240 Pins, Non-ECC Unbuffered, CAS 5-5-5-12 (£58 x 2)

or..

2GB (2x1GB) CorsairTwinX XMS2, DDR2 PC2-6400 (800), 240 Pins, Non-ECC Unbuffered, CAS 4-4-4-12, EPP (£68 x 2)

Is there much difference? It's going to be used in a Asus P5K-E motherboard and a Q6600 processor which a few months down the line I hope to overclock to around 3GHz (probably no higher) if that matters?

I'd appreciate any opinions,

Thanks.

I doubt you would ever notice the difference.

No. Its splitting hairs.
There is a good chance they are the same anyway, just with a different SPD table. The "cheaper" stuff will probably do the same as the other, even if it needs a tad bit more voltage.

Great, Thanks.

Will use the £20 saved to upgrade something worthwhile.

I have the £58 stuff, runs fine at 4-4-4-12 / 800 on my HTPC setup. And it didnt even need any extra juice :)

If you are only going to 3GHz I would of thought you would have been plenty comfortable with PC2-5400 which Corsair do in XMS2 4-4-4-12 flavour for about £50 a matched 1GiB pair. Of course if you are getting into watersports later the faster RAM may give you more headroom.

That £58 RAM looks like a bargain, I was going to get http://www.microdirect.co.uk/(16746)...R2-PC6400.aspx but I'm trying to save as much as possible so that I'll pick that at £7 cheaper.

Just browse through reviews from here and see that there's no noticable difference between CAS4 and CAS5 on C2D platform

i would go for the £58 stuff too...and just run it at the £68 stuff's timings
