How to read memory SPD?

If I’m not mistaken, by looking at memory frequency we can roughly know one’s memory brand is better than others. But the problem is that I don’t know how to read/understand by looking at that RAM timing such as my Corsair Value Select stated by CPUZ as 5-5-5-12-1T. Is my Corsair better than a Patriot that has timing 4-3-3-12?

Any information will be much appreciated.

timing-wise, the lower the better (meaning the Patriot has your Corsair for lunch).
Now, the impact of having the Patriot in place of your Corsair is 1-2% with an AMD processor, and almost nil with a Core2.
CPU-Z will give you all that's in the SPD, including timings per clock speed (there can be several profiles recorded for several clock speed).

Since the manufacturers intentionally choose relatively slow settings for the SPD in order to maximize compatibility, SPD settings are pretty much useless for evaluating module quality.
Another program you can use to look at memory (and other) info is PC Wizard 2007.

Frankly, it depends - some memory will be able to handle tighter timings than specified, others will hang if you try to push them.
The Corsair might me pushed some; the Patriot, you MIGHT be able to remove a point for the first parameter (CAS).

So, which one is better? DDR2 667 Corsair Value Select 512 Mb PC5300 or DDR2 667 Patriot Signature Line 512 Mb PC5300?

on an AMD system, the Patriot will give you a 2-10% boost; on an Intel system, the Corsair Value has hardly any speed penalty and costs less than the Patriot - and comes with a lifetime warranty.

You do the math.

My system will be:
Intel E6400 2.13 Ghz
Gigabyte GA-965P-S3
XFX 8600GTS/8800GTS? (still undecided)
Western Digital Caviar 80 Gb SATA
SilverStone ST50EFPlus 500W

The price for Corsair Value Select is $. 29 Lifetime warranty and Patriot SL is $. 33 with heatspreader. Personally I like patriot over Corsair just because it has heat spreader but I dunno both brands timing and their performance will do best for my upcoming system, plz help me choose. thanks.

I have no experience with Patriot RAM, but i definitely know that corsair makes damn good stuff.. I would choose corsair... The Corsair XMS 2 DDR2 667 range isnt much more expensive than the value select, maybe you can check that out also.

Unfortunately, while Corsair's premium lines are top-notch, their ValueSelect line is no better than generic RAM (except for the good warranty). They just contract it out to the cheapest bidder and then slap a Corsair label on it.
I'd say the Patriot is definitely better.

Since I don't have anymore budget to spend on RAM (especially Corsair XMS or Dominator) just because I will overspend on GPU (8600 is bad, I'll choose 8800GTS 320 Mb extra $. 100 more) I think I will test on that 2 brand before purchase and see which brand timing offer the best. I'll let u guys know ASAP. Thx

I won't disagree on this. In that case, the similar offer from Kingston would be more interesting: same warranty, similar prices, and all the chips I have tested were very good and stable.

I've tried Kingston Value before, its timing 6-6-6-15 is worse than Corsair Value Select 5-5-5-15.

on a Core2, this has hardly any effect.
