Intel Pentium G645

Hello guys, I have a question. It says on Intel's site that the G645 can only support DDR3-1066. Does that mean that a DDR3-1333/1600 will not work with this CPU? I am building a new system soon and this processor fits perfectly with my tight budget. I am sorry, I'm noob when it comes to computer stuff.
Any help is much appreciated :D

my PLANNED specs:
Gigabyte H61M-DS2
Intel Pentium G645
G.skill 4gb DDR3 (1333/1600mhz)
500gb WD HDD
Sapphire HD 6670 1gb GDDR5
Antec VP550

  1. DDR3-1333/1600 will work. It simple gets "downgraded" by the motherboard.
  2. Yes, the motherboard auto-downclocks the RAM speed, so it works. I thought it supported 1333 though, weird..
    Anyway, I have a similar system being planned out friend! G860, MSI H61M-P31, Crucial RAM, and a 7770 :)
  3. if you mean downgraded it is slower, right? :) thanks for the quick replies guys
  4. hi! is that MSI motherboard better than the Gigabyte? I heard from a friend that MSI mobo's have high failure rate and that i should go with Asus or gigabyte only. Is that really true?
  5. It's all preference, I mean, Gigabyte & MSI both make really good boards! MSI doesn't have a high failure rate, I mean come on, every company has their own bad batches. Just so long as you go with either an ASUS, Gigabyte, or MSI board you'll be good - they're known as the big 3 for motherboards!
  6. I have the G645 and MSI H61M-P31 :p built it a couple of days ago, this motherboard has OC genie for overclocking "K" series cpu.. very useful I think because practically you can't overclock on an H61 chipset..
  7. Dude better to get g860 3.0ghz and 1333mhz at same price.
  8. ^ I agree, but the G860 is $5 more on newegg.. but it's worth the price because of the higher ram frequency and 100MHz speed bump.. Good for gaming.
  9. i have a very similar system as the OP is planning to build. its a great budget system for gaming . though you might wanna go for 7750 instead of 6670
    will give you a good performance boost

    Not really!The frequency will be lower, but the latency will be better (i.e. 7-7-7-20, instead of 9-9-9-24). Some utils, like HWINFO64 can read the SPD, the tiny chip on the stick, that contains the table of parameters for different frequencies.

    I would love to, unfortunately I can't a find a store who sells g860 here in my country.
  12. Which country are you from?

    Is it worth the $30 difference? because here in my country the 7750 is about $110 while the 6670 is only $80 :) if it's worth then I'll go with the 7750

    Philippines. components are really expensive -_-
  15. Yes its worth to get hd 7750 much faster than hd 6670 and consumes less power.intel g645 can easily handle upto hd 7770.go with it

    Thank you! last question, with the 7750 and g645, at what settings can I run far cry 3?
  17. High at 1366@768 or at 1280@1080

    hello fella! i'm from Baguio City... I think tipidpc and pchub are Manila area only, right?
  22. Nope, only PCHub, tipidpc is like ebay where you can buy or sell pc components. May be you can find some shops near you in there!
