I was going for Kingson ddr2 667 and noticed this Corsair for just 10 bucks more. Would it be a better fit for my new build - current specs of a E4300, Gigabyte DS3 (or DS3P if it gets out anytime soon) and a 7900GS GPU?

Which Kingston DDR2-667? Compared to which Corsair? You didn't provide this info so we don't know which specific products you are talking about. :?

Also hard to give any info about whether the memory is suitable without some idea of how you think you will use your system. :?

Sorry about that. This will be a game maching and some video. If it can handle that, everything else will be a breeze. I plan on OC to around 3, but nothing more aggressive, at least not now. I do want to move to the 8800GTS when prices come down.

The Kingston mem is this:

The Corsair -

I'm open to any other suggestions, I'd like to keep it under $200, fast, stable, cool, overclockable.

Oops! Maybe I got a little carried away at the end there. Best bang for the buck in reliable mem.

Well, I suppose I should begin with the disclaimer that I'm no memory expert. I probably know about as much as you, maybe less, and I hope one of the other folks out there who actually look at the memory chips will respond.

On the face of it, DDR2-667 should not have any problems with the 333MHz clock you want to try to OC the E4300 to. The Corsair appears to be both cheaper after the rebate and 1 CAS clock faster. If it were me I'd go with the Corsair. Unfortunately, this is probably just a rehash of what you were already thinking.

OTOH, if it were me I'd also ... perhaps very foolishly ... be looking at CORSAIR XMS2 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) and thinking some crazy thought like for the extra $26 I'll "future proof". However, every time I've tried going down the FP road it's never really worked out for me. Always seems that when the future arrives there's something even better for less money. :oops: Still, I can't seem to break myself of the reflex.

Whatever. It is nice that DDR2 prices have dropped a bit recently, isn't it? I wonder why it's happening and how long it will last.

Out of curiosity, what motherboard are you thinking of going with for your E4300? I've been speculating about one of the Gigabyte rev. 3.3 boards ... if they show up soon enough.

Thanks for the response, zjohnr. Yes, I was leaning the Corsair way for the reasons you meantioned, but also it has a better reputation than Kingston, I believe. I also like the fact that the Corsair has heat spreaders. Also, the DDR2 800 corsair is actually $181 after a $40 rebate.

Memory, monitor and power supply - just can't seem to get a good fuzzy feeling on any of them. My board that is on my list now is the GIGABYTE GA-965P-DS3

http://www.newegg.com/Product/Product.asp?Item=N82E16813128012

There is a new version out, but not here yet, the DS3P (DSR rev 2) which addresses some problems on the DS3. It cost a little more but has additonal features also.

Maybe the price drop is due to Vista release. Alot of mem to be sold for that upgrade.

:? Yes, DDR2-800 is $181 after rebate or $26 more than the DDR2-675 which is $155 after rebate, no? :? Sheesh, after where the DDR2 prices have been, $155 net for 2GB feels so very compelling.

After staring at the Gigabyte website for a bit, I think that what the GA-965P-DS3P (rev. 3.3) offers over the -DS3 or -S3 is that the DS3P has two PCIe x8 graphics slots and supports ATI CrossFire. This is not anything that would interest me. Having 3 PCI slots is much more important to me so I'm thinking of going with rev 3.3 of either the -S3 or the -DS3. Depends on whether I'm swayed by the market allure of "solid caps" or if sanity prevails. :wink:

Maybe the price drop is due to Vista release. Alot of mem to be sold for that upgrade.
I would expect the price to go up if people were buying more RAM for Vista. So perhaps Vista upgrades are not happening and the surplus of memory is driving the price down? Who knows ... all just speculation. I just hope I don't wait too long and miss a buying opportunity.

I second to Mondoman. Corsair mem is CAS4, Kingston mem is CAS5. I'd choose the Corsair memory over Kingston for 10 bucks more. It's actually cheaper with the Corsair if you count in the rebate.

IMHO, Kingston does not have a good reputation in the DDR2 high performance memory market (they might have in the DDR, but not DDR2). Their memory line may be good for the "value" (low end) market, but when it comes to the DDR2 high performance market, their HyperX memory line runs into quick sand for being too expensive for most of the OCer. Corsair is one of the top brand to get.
My $0.02. :)

One more thing Billyc. Since you want to get the memory for your E4300, may be you should seriously consider DDR2-800 instead of DDR2-675. The reason is simple, other C2D have 1066 FSB, i.e. quad-pumped from 266 MHz, E4300 FSB is 800 MHz, i.e. 200 MHz quad-pumped. With DDR2-800, you will run with memory ratio 1:1 by default instead with some other odd number as with other DDR2 speeds. This is for OCing only. If you don't plan to OC, stay with the Corsair DDR2-675.

... E4300 FSB is 800 MHz, i.e. 200 MHz quad-pumped. With DDR2-800, you will run with memory ratio 1:1 by default....
However, if he runs in dual-channel mode, DDR2-800 will have 1600MHz effective data transfer rate, or double that of the 800MHz FSB. I don't think he'll be able to OC an E4300 2x to a 400MHz FSB clock, so DDR2-800 is probably better for OCing the 267MHz default FSB clock C2Ds to 400MHz FSB clock.

I agree with everything you guys came up with. I'm changing to the Corsair ddr2-800 at that price. I've been concerned about the Kingston for awhile anyway. That's a great price for great mem. I will be OC'ing, but not too aggressively, this is all new to me. If I can hit 3.0, I should be good to go. I'm also going to go with the EVGA 8800GTS instead of the 7900GS.

Now on to another forum to finalize my case and power.

Ok, so my question is kind of similar.

I have a motherboard that says it goes up to DDR 550....

what would happen if I throw that DDR800 ram in there?

:? DDR 550 :? I'm confused so a few questions.

Are you talking about DDR2-550 or DDR-550 ... very different critters. DDR2-800 would not even fit into a DDR motherboard. Different number of connectors, different key slot position on the DDR2 memory stick. And I am thinking at the moment that you might have a DDR motherboard.

Why not just post the make and model of your motherboard then we can look up the specs. (I'm curious now).

Finally, assuming your board supports DDR2 and you installed DDR2-800 in it then it should work. But it would probably be running at a much lower speed than it is capable of running. (i.e. you wouldn't be getting your money's worth).

You confuse me Mondoman. I thought DDR2-800 has base clock of 400 MHz and double rate would give 800 MHz (not 800 x 2 = 1600 MHz). DDR-400 or PC-3200 runs at 200 MHz, double rate would give 400 MHz.

Correct me if I'm wrong, but I think DDR2-800 indicates the actual combined speed and not before the double rate. If Billyc puts DDR2-800 memory to run with the his E4300, both would run at 800 MHz (DDR2:CPU ratio is 1:1). When you overclock it, you OC both mem and the CPU at the same time.

Noman, you're pretty much right. I was just pointing out that you were not taking into account dual-channel mode, which doubles the throughput yet again. DDR2-800 has a 400MHz memory bus clock, an 800MHz effective data transfer rate in single channel mode, and 1600MHz effective data transfer rate in dual-channel mode.
