Questions about Mobo/cpu/ram FSB's Upgrading system?

Hi, i want to upgrade my brothers computer. Here are the hardware im planning to get:

CPU: Intel Dual Core E5400 2.7GHz 2MB 800MHz:

-SPEED : 2.70 GHz
BUS SPEED : 800 MHz
BUS/CORE RATIO : 13.5
L2 CACHE SIZE : 2 MB

Motherboard: Asus P5G41T-M LX Intel G41 ICH7 mATX LGA775 DDR3-1333
-CPU Intel® Socket 775 Core?2 Quad/Core?2 Extreme/Core?2 Duo/Pentium® dual-core/Celeron® dual-core /Celeron® Processors
Support Intel® 45nm Multi-Core CPU

Chipset Intel® G41 / ICH7
Front Side Bus 1333/1066/800 MHz
Memory 2 x DIMM, Max. 8 GB, DDR3 1333(O.C.)/1066/800 Non-ECC,Un-buffered Memory
Dual Channel memory architecture

RAM: SuperTalent DDR3 1333MHz 2GB PC10660

-So I wanted to know that since my RAM is at 1333MHz and my motherboard needs that to be overclocked to support that amount, does that mean it will still work when i first install it?

-Also, can someone please explaing what bus/core ratio is?

-Also is my proccesors bus speed slow since its only 800mhz?

- For example, if i were to have a processor, which had a bus speed that was higher than the motherboards FSB, would it still work? if it did, would it slow down the processor clock.

lol i know its pretty long, but just need some clarification.

  1. I don't recommend socket 775 at all.

    go up to 1156 and an i5-750 or go to an amd AM3 chip
  2. What hardware is currently in the computer?
  3. Current:
    -Pentium 4 - 3.0GHz (not overclocked)
    -ASUS P5S800-VM
    -1GB DDR400 RAM
    -ATi Radeon AGP card (forgot the model) 128MB
    -500GB SATA hdd

    Yea the reason behind the upgrade is that I think the motherboard is dead. because i cannot get it to post, no beeps no display. Just fans spin. I have tested PSU, all fine. I have done all diagnosing, reseating memory, taking out gfx. etc

    So Yeah.
  4. Hmm.. ok. I'd still either go for a 1156 platform or AM3.

    What budget are you on and what're you using this for (gaming, photoshop, general use etc)?

    To answer your earlier questions:

    1) Using the correct settings You can natively use 1333 on 1156 and AM3 afaik, I'm not sure the limits on 775

    2) I thought I knew the answer to that.. but then looking at what you've said I don't actually know. sorry bout that.
    Ed: I think this is the ratio between FSB and bus speed.. mb? lol I'm just having guesses here.

    3) Bus speed doesn't really matter in CPU speed if the total speed is still high. bus speed is just one of the things that, when put together, make up the CPU frequency.

    4) Not really sure on that...

    Anywho.. answer and first set of questions and we'll go from there.
  5. Since i'll be using my old case, hdd, monitor etc. Ill only need to get the cpu, mobo, ram. My brother will mostly be using it for causual things such as email, internet, watching movies and Photoshop.
  6. ok, a casual computer. What's your budget?
  7. i guess around 500 or lower, since i dont need to get other parts, just cpu, mobo, ram.
  8. Hmm. I'm thinking an Athlon X3 build. What about you Mr/Miss Squirrel?
  9. sounds about right. MAYBE an SSD for faster OS boot since no HDD/Monitor/Case.

    Let me stretch my newegg legs. I'm thinking an 880 Mobo, an X3 or x4 Athlon II, 4 GB of RAM, a new PSU (400W-ish) just because of the age of the PSU in the P4, and maybe a low-end graphics card
  10. yes. here's a build:

    AMD Athlon II X4 640 (3.0 GHz) Plus Gigabite 770 motherboard with 2 USB 3.0 ports: $162.98 + $10 MIR
    http://www.newegg.com/Product/ComboDealDetails.aspx?ItemList=Combo.524271
    the motherboard doesn't have SATA 3 (but you won't be using it), but does have 2 USB 3.0 ports for future needs.

    Mushkin Enhanced Callisto Deluxe 40 GB SDD: $99.99
    http://www.newegg.com/Product/Product.aspx?Item=N82E16820226168
    40 GB is enough for an OS boot and several applications you use all the time. Mushkin Callisto uses the newest Sandforce 1200 controller for maximum lifetime out of your disk.

    Mushkin Essentials DDR3-1333 4 GB: $66.99 + $10MIR
    http://www.newegg.com/Product/Product.aspx?Item=N82E16820146748
    Basic DDR3 RAM, cheap, yet from a reliable brand. Its hard to argue with this price.

    Xigmatek PC-402 400W 80+ Bronze Power Supply. $39.99
    http://www.newegg.com/Product/Product.aspx?Item=N82E16817815007
    This was reviewed a couple weeks ago, and managed something like 645 or 685W at peak power. It is probably the exact same parts as the 600W version

    EVGA GTS 450 1 GB Video card: $129.99
    http://www.newegg.com/Product/Product.aspx?Item=N82E16814130572
    I picked this because it had free shipping. There is a gigabyte that's the same price with a $20 rebate, but it was $8.00 shipping. This card is nicely factory overclocked too. As it is, it will handle any game thrown at it at resolutions up to 1600x900.

    total cost: $499.94 with $20 in MIR, and $11.49 shipping.
  11. Wow. Thanks alot guys. im going to take this into consideration seriously. Thanks again both of you!
