Help!!! Memory Choices. DDR2 800 vs. DDR2 1066.

If the prices are similar, go with the faster (1066) RAM. Otherwise, go with the cheaper RAM.

How about you get Crucial Bullistix 800mhz Cl4 MicronD9 2x1GB dual channel pack for 70$ after rebate or OCZ 1066mh Cl5 for 100$ 2x1GB dual channel package after rebate for only 100$. A simple glance at newegg memory section and you'll see it. Either way, both sets are lower than your 140$ budget after rebate.

Edit: I see you spotted the 70$ 2x1GB Crucial deal too.

Can someone please explain to me or give me a link to explain about the differences 800 and 1066 RAM would make and if it would help a lot at all during overclocking having 1066?

Thanks.

Here's a good link for lots of info for 800mhz vs 1066mhz.

it will just give you more headroom with your overclocking. the actualy performance in ram itself is very small- 533, 667, 800, etc.

but if youve got 1066 ram, you know you can freely mess around with any speed below that, whereas with 800 you may or more not get past 800.

That just takes you to the memory forums.......

Thanks for replying, I will probably sell my 4GB of 6400 DDR2 Ram I have at the moment as they aren't compatible with the motherboard I want and get some good 2GB DDR2 1066mhz.

If you do video editing then why aren't you getting the Q6600? It is going to be $266 after the price drop.

Money is the main reason and I don't do a lot of it. Also, I would go with the OCZ DDR2 1066, but it isn't on the list of memory for this motherboard and at Newegg it says that it only supports the supported memory.

(click on memory support list)

Don't trust that memory thing as on the RAM's websites such as crucial and corsair it says some ram not on their is compatible!

Get the Crucial Ballistix 8500 1066mhz RAM from newegg that is compatible with that mobo if it is the same one I'm getting and its quality stuff. Check the crucial website, it confirms its compatible.

If I was going to get DDR2 1066 I would want to pay $180 plus for it. Max at $140!

According to this from Gigabyte, the OCZ ( OCZ2N1066SR2GK ) is on the list. DDR2 1066 and it can run dual channel????

OCZ2N1066SR2GK which is found at Newegg under:

I'm not entirely clear on this, as this is why I started a new thread to see if anyone here was using this particular mobo and memory combo.

If you don't plan on overclocking go with cheaper DDR2 667 as it will run at a 1:1 fsb ratio with your 1333mhz fsb processor. DDR2 800 will allow you to run your processor at 1600mhz fsb or 3.2Ghz.
Just because the motherbord supports DDR2 1066 dosn't mean you have to use it. The differance in memory speeds is small if you don't OC.
I would try the 4Gigs of ddr2 800 you already have, more than likely it will work. I have yet to find DDR2 memory that will not work on DDR2 motherboard.

Well i was confuse about which to get 800 or 1066 ram model I think 800 will be best if your getting an q6600 9x333 -- ddr 800 going to running at 677.

The Q6600 runs stock at 9x266. DDR2 800 at 1:1 would only run at 533. 9x333 would OC it from 2.4Ghz to 3Ghz, you would still only be at 667. IMO if you do not OC you do not need faster ram.

so i dont need the 1066 model ram do i?800 will be fine at 3.0 on q6600 right as you said 9x333 .

yes 667 ram will be fine, unless you want to overclock, because you will get a 1:1 ratio with the 667ram

The E6750 will run @ 2.67Ghz by default with DDR2667 RAM.
DDR2-800 (Not OC'd) will allow for speeds of 3.2 Ghz
DDR2-1066 will allow for speeds of 4.27 Ghz

Traditionally 3.2Ghz was a good OC number for the C2D and higher OCs may not have been very safe due to heat/voltage issues.

However, the new 1333FSB chips have a new stepping that will allow for much highe OCs at low temps/voltages.
Rumors of stable 3.8+ on STOCK coolers with 4.0+ on top end air coolers.

This means that the DDR2-800 Ram may be limiting in your OC potential because of the new steppings.

My advice, go with 2x 2gig @ 800fsb ($140 after rebate?) filling 2 of the dual channel slots, doubling the memory to 4gig (MUCH faster than 2gig @1066) and better performance. Still within your budget, better performance. Don't skimp on a video card. With the box you are building you will want at LEAST a 512 meg vid card (1 gig would be better). This alone will take a load off your processor and system ram.
I have a similar gigabyte board, and pretty much went / going with the same as I am recommending. (bought 1x 2gig ram stick and adding another... remember, you dont HAVE to add them all at once ;o) )

PS... I also recommend against overclocking. You really don't get that big a boost and it usually comes at the cost of stability and reduced system life (mostly due to the excess heat from the overclock)
