Motherboard / CPU mismatch - Would it work?

Here's a general queston. Just wanted to updated my knowledge.
My Motherboard has FSB of 533 MHz.
Would a CPU of higher (say 800 Mhz) or lower (say 233 Mhz) speed work on my Motherboard??

CPU with 800MHz frontend-no
CPU with 233MHZ frontend-yes
it is going to be off sync.
may go to have some issue down the line, mainly sped issue, since the frontend want to run at 533MHZ anything close to it should be fine but not more than 10% difference. spec tolerance.

I have motherboard Mercury PVM7P, i installed 2 GB DDR2 RAM 800 MHS but its showing only 448 MB what is the solution for that anybody can solve it, how much maximum RAM can support this motherboard


Hello you can find info here:

http://www.mercury-pc.com/product-detail.php?link=p-mainboards&subtitle=Mainboard&productid=677

The mainboard supports:

2 x 240-pin DDR2 DIMM socket support up to 2 GB DDR2 533
Maximum: 2GB

533 mhz is probably limited speed by the CPU and the FSB settings.
So you have to try with another type of ram module, the 533 module, because 800 mhz is probably to fast for this mainboard.

Good luck

HP Pavilion Media Center PC not detecting memory in slots 3 & 4.All memory works in slots 1 &2.Memory is all the same.


Info from the manual:

Memory configurations

You can install 128 MB, 256 MB, 512 MB, and 1GB DDR SDRAM DIMMs into the DIMM sockets using the memory configurations in this section.

• Install only identical (the same type and size) DDR DIMM pairs

using the recommended configurations.

• Make sure that the memory frequency matches the CPU FSB

(Front Side Bus). Refer to the Memory frequency/CPU FSB

synchronization table on the next page.

• This motherboard does not support double-sided 16-bit DDR DIMMs.

• Do not create a three-DIMM configuration in dual-channel mode. The
third DIMM is ignored in the dual-channel operation.

Power on ok but no display. ram not detect


First disable the onboard VGA then put in a known good AGP graphics card to see if you can get through the POST if your BIOS i rejects the RAM chips it should give you a short series of beeps this would indicate that the memory is not compatible as a rule of thumb PC2700 speed memory is for a motherboard and processor with a 133Mhz FSB this is quaded to 533MHz. you can usually place faster memory but not slower memory look at the table below for rated Frontside Bus Speeds.

800 MHz PC3200/PC2700*/PC2100 400/333*/266 MHz (min busspeed 200Mhz)
533 MHz PC2700/PC2100 333/266 MHz (min busspeed 133Mhz)
400 MHz PC2100 266 MHz (min busspeed 100Mhz)

Replacement for INTEL Desktop board D865GLC


I've found an Asus P4SD i865GV online:
http://www.geeks.com/details.asp?invtid=ASUS-P4SD-NOAGP-R&cat=MBB

It seems to have the same CPU socket, FSB and RAM types, and the chipset is almost the same model. I'd say this would work.

If you can't get that, just make sure to get a motherboard with the following qualities:

Front side bus (FSB): 800, 533, and 400 MHz
RAM type: Dual Channel DDR 400 MHz (PC3200), 333 MHz (PC2700), and 266 MHz (PC2100).
CPU socket: 478

I have 810 bu mother board


your board is compatible with pentium 3 processors through the "coppermine" revision, the pentium 3 "tulatin is not supported" here is a list from wikipedia of the "coppermine" processors supported by your board.:



Coppermine
  • 100 MHz FSB: 500, 550, 600, 650, 700, 750, 800, 850, 900, 1000, 1100 MHz (E-Models)
  • 133 MHz FSB: 533, 600, 667, 733, 800, 866, 933, 1000, 1133 MHz (EB-Models)

Coppermine-T (the only coppermines with an attached heatsink)
  • 133 MHz FSB: 800, 866, 933, 1000, 1133 MHz

The Tulatin core is NOT compatible with intel 810 boards, and they can be easily confused with the coppermine-t's because they also have attached heatsinks.
