800mhz or 1066mhz memory?

I am about to order a new pc from www.cougar-extreme.co.uk I have chosen the Q6600 and the Gigabyte GA-P35-DS3R, which supports 1333mhz fsb and 4x DDR1333.

I can get 2 x 1Gb Corsair 1066mhz Ram for an extra £108 pounds, or 2 x 2Gb of Corsair 800mhz Ram for an extra £116 pounds.

Seems like a no brainer to me and get the 4Gb of 800, I am assuming all else is equal exept the speed. I dont know much about memory but I know can OC it to a degree and the extra speed doesnt seem as good as having twice as much. Looking for opinions, Thanks.

  1. If you machine comes with Vista 64bit version then get the 1066mhz memory but if its vista 32 or windows xp 32bit edition then consider only getting 2gb of memory any how.

    Otherwise your right , its a no brainer.
  2. I disagree - IMHO, you should go with the 2x2GB DDR2 800 choice. At a FSB of 1600, your Q66 will be at either 3.2Ghz (8 multi) or 3.6Ghz (9 multi), and you will be able to run the that 4GB of DDR2 800 stuff at 1:1. From personal experience on a different mobo - the Q66 likes 8/400.
  3. There is no such thing as DDR2 1066 according to JEDEC. Memory sold as 1066 is just quality DDR2 800 which the manufacturer guarantees will work at 1066 speeds overclocked but any quality DDR2 800 will easily reach those speeds and more. My suggestion would be to get the 800 and overclock it youself and as Scotteq wrote you won't need to overclock 800 until you get over FSB1600 anyway.
  4. Ye I also thought 800 was the max for DDR2, This '1066' stuff just seems like a total rip off. I need to get more info from them before I buy it, could it be 800mhz Value Select or something? hence cheaper price. The whole website is pretty vague but also cheap, check out the configure you PC page.

  5. I would also appreciate if someone could throw their eyes over the cases on that page and which looks good, I am willing to buy any exept the £250 water cooling one :). Cooling is more important than looks to me than looks. And Preferably doesnt sound like a jet taking off when I boot it up.
  6. I think the best case on there is the Aurora, check it out here

    As for the RAM I would just call them and ask, find out the brand, rated speed, latency, and voltage. Then you can use that info to see if it's really a good value or if their trying to pull something over on you.
  7. He gave me the model number CM2X1024-6400C4 for memory
  8. exept it will probably be the 2gig version of that
  9. My best guess is they will use this for 4Gb.


    So it would be 5-5-5-18, is that any good?
  10. If they gave you that model number their probably using 4 sticks. Here's a review
