Question 1

is it  interchangeable with e6700?

Accepted Answer

They're both LGA 775 sockets, so "yes" either will fit if your motherboard has the same socket.

HOWEVER....It might not *work* in your motherboard if the manufacturer (usually the BIOS) doesn't support it.

The best thing to do is to go to your motherboard manufacturer's website, and confirm your motherboard will work with this particular CPU. Some manufacturer's offer a BIOS upgrade to allow it to work with newer processors, while others don't.

Question 2

i have this mobo on my pc evga nf66 nForce 650i Ultra, using an Intel Core Duo E6420 and want to make sure would this processor be compatible with my system and would i notice a speed increase?

Accepted Answer

IMO, not worth the upgrade.  Here are the specs of the two, from the Intel website:

Status  EOIS 
Launch Date  Q2'07 
Processor Number  E6420 
# of Cores  2 
Clock Speed  2.13 GHz 
L2 Cache  4 MB 
FSB Speed  1066 MHz 
FSB Parity  No 
Instruction Set  64-bit 
Embedded Options Available 
  No 
Lithography  65 nm 
Max TDP  65 W 
VID Voltage Range  0.8500V-1.5V 
Recommended Customer Price  N/A

Status  End of Life 
Launch Date  Q1'09 
Processor Number  E7500 
# of Cores  2 
Clock Speed  2.93 GHz 
L2 Cache  3 MB 
FSB Speed  1066 MHz 
FSB Parity  No 
Instruction Set  64-bit 
Embedded Options Available 
  No 
Lithography  45 nm 
Max TDP  65 W 
VID Voltage Range  0.8500V-V1.3625 
Recommended Customer Price  BOX : $125.00
TRAY: $113.00

Notice your processor has 25% more l2cache, which is like internal memory on the processor, before it hits the ram.  While the clock speed is higher on the E7500, you will lose performance on multitasking or demanding applications.

Also notice the voltage range on your processor is higher.  My suggestion on that system, approaching End of Life anyway, is tweak the FSB and voltage (overclock it) with mother board settings, and drive it like you stole it till time for a new computer.

Question 3

Does this come with heatsink and fan? How much improvement over the 6400?

Accepted Answer

I ordered this product a few months ago. It does come with a heatsink and fan assembly. Unfortunately, I don't know how far it outperforms the 6400 model. I upgraded from a single-core CPU, so for me the improvement was very significant.

Question 4

Is this interchangeable with the intel E2200? And does this have integrated graphics support?

Accepted Answer

I can't say for certain if they are interchangeable. They are both socket LGA775 processors but the FSB speed is different (and I honestly don't know if that will make a difference). As for graphics, these processors don't have graphics integrated - that would come from the motherboard/chipset. Only the newer gen processors have the graphics on board with the CPU.
