Find a better 4GB kit than this?

G.Skill, DDR2 800 2x2GB.

Anyone know of a better kit (meaning price:specs)?

This one is nice, but expensive:

Same specs but $57 after rebate. OCZ rebates are usually trustworthy (I did 4 and all good).

As for the other one, that's DDR3 and it may not work on your laptop. Besides, you can get DDR3 for much cheaper than that.

 

OCZ 2x2GB PC2-6400 DDR2-800 CL=5 (5-5-5-15)

57 BUCKS after $25 MIR (Expires 31 Aug, 08)

EDIT: ^ The same

 

What laptop do you have? On the Intel side, only the newest Montevina platform supports DDR2 800 and DDR3. Older Napa or Santa Rosa platforms only support DDR2 667 so getting DDR2 800 won't help you.

 

You're comparing DDR2 and DDR3 in those links. Make sure to only get what will work in your notebook.

If your notebook only uses DDR2, DDR3 will be useless to you... Also, say if your motherboard maxes out at 667 getting 800 would be a waste of money.

Look in your manufacturers spec sheet or check out the crucial memory adviser to see what your notebook maxes out at. Once you know that we can compare.

 

Wonderful! I like OCZ. Thanks, that's great. Dell is going to charge me $210 for 4GB on the new E6500 latitude, figured I could get a DDR2-800 (which is what they give) for cheaper.

75% cheaper and good brand sounds worthy to me .

*Oops, seems like I'm a bit ignorant. The laptop I'm purchasing is E6500 which offers up to 8GB RAM, so what do you guys recommend? 667 or 800? DDR2 or 3? I thought the processors in this guy would be manly enough.

 

It'll just downclock to 667MHz so there's nothing wrong with buying 800MHz RAM for a Santa Rosa laptop if it's a good price.

 

^ Yes, and the timings will also downclock from 5-5-5-15 to 4-4-4-12....alongwith the frequency, so the OCZ DDR2-800 kit falls out to be much cheaper and better than most 4GB DDR2-667 CL=4 Kits

 

If it's a good price is the key assumption there. It's important to know what your notebook can handle so you don't spend extra on speed you won't use.

DDR3 has a few more pins I believe. If that's the case then it's a matter of incompatibility, not downclocking.

 

Yes DDR3 is totally different from DDR2. They both have different sockets....

 

I have the OCZ in my laptop:

Works great, no complaints. Highly recommend it.

 

I was referring to DDR2 800MHz RAM and Santa Rosa laptops. You must have quoted me within the ~30 seconds that passed after I posted before I edited it.

 

I don't believe that's true. I'm pretty sure DDR2 667 4-4-4 timings is actually more aggressive than DDR2 800 5-5-5 timings. I'm pretty sure DDR2 800 DIMMs only downclock to DDR2 667 5-5-5, although it may have changed since the last time I checked was when DDR2 800 SODIMMs were first announced.

 

No that it is not true by any means. The timings are pre-coded for each frequency rating. If the frequency downclocks, so do the timings. If they wouldn't, the whole DDR2 backward compatibility thing would have been considered as useless.

For eg. My CPU's FSB is 533MHz (133MHz), and I have PC2-5300 DDR2-667 CL=5 RAM installed with timings 5-5-5-15.

My ram has downclocked to PC2-4200 DDR2-533 (266MHz) - with timings 4-4-4-12....

Same was with my old D630, in which I initially had a T2330, with DDR2-667 CL=5 RAM, and the frequency and timings with the T2330 were 533MHz (266MHz) and 4-4-4-12, but after upgrading to the X9000, my RAM functioned at a frequency of 667MHz (333MHz) with timings 5-5-5-15....

 

I wasn't questioning that DRAM makers provide for lower frequency operation in their SPD chip, I was only saying that DDR2 800 with 5-5-5 timings probably downclock to DDR2 667 with 5-5-5 timings rather than 4-4-4 timings.

DRAM frequency and timings do not have to change together. RAM standards are determined by JEDEC, and when DDR2 667 was first released the official standardized timings were 5-5-5. It was only in a later revision of the DDR2 spec that DDR2 800 was added at 5-5-5 and DDR2 667 with 4-4-4 timings was standardized. DDR2 667 SODIMMs seem to have standardized at 5-5-5 timings which is why they are so common while the newer DDR2 800 SODIMMs are also 5-5-5. There is no requirement that DDR2-800 with 5-5-5 timings must lower their timings to 4-4-4 when operating at DDR2 667.

You can see that the DDR2 667 memory that Intel validates seem to operate at 5-5-5 timings. So it would make sense for backwards compatibility that DDR2 800 supported DDR2 667 at 5-5-5 timings since it's more widely supported.

 

Memory Timings are directly related to the Memory Frequency....
