MY LAPTOP'S MODEL IS HP COMPAQ 315. WHAT IS THE MAXIMUM RAM AND MAXIMUM PROCESSOR OF HP 308C KBC MOTHERBOARD.

Hey;

Start your computer and right after the hp logo, keep pressing the F8 button until you see a large list of options.

Select

"USE LAST GOOD KNOWN CONFIGURATION"

and press enter. Let windows load and it should work just fine.

That's an old mainboard (Motherboard), used in a Compaq Presario 5716 desktop computer. (And perhaps a few other Compaq Presario's)

1) Uses a Slot 1 (Intel) processor slot.

http://en.wikipedia.org/wiki/Slot_1

2) Maximum Intel Slot 1 processor that can be used, is an Intel Pentium III, with a 100MegaHertz Front Side Bus. (100MHz FSB)
Maximum frequency rate for the processor is 700MHz.
('Speed')

(Scroll the page down)

3) Ram memory is SDR Sdram at 100MHz. Or also known as PC-100. (168 pin. 82 on each side. Two Locating Notches on bottom. Commonly just known as Sdram, but that is a misnomer)

http://en.wikipedia.org/wiki/PC100

Maximum TOTAL Amount of ram memory is 384MegaByte.
Maximum Amount for each ram memory slot is 128MB.
There are 3 ram memory slots.

4) Do not know what the jumper settings on the motherboard are.

5) Do not know what the Front Panel header pinout is.

6) Can run Windows XP Home Edition, but do not expect a world of performance.

This is info on your motherboard:
http://h10025.www1.hp.com/ewfrf/wc/document?lc=en&dlc=en&cc=us&docname=bph07843
Your system comes with Intel P4 2.53 GHz processor and 512MB ram. total ram could be 1GB, bt adding another 512MD stick. You have Socket 478 and processor would be up to you. The system comes with a 200w power supply so, in an upgrade, you should up the power supply. You have an AGP expansoin slot and, you could upgrade to a graphics card but again, power supply is only 200w. The system as it stands is not Windows 7 compatible. If you incraesed your ram and got a graphics card, you would get better performance.

Yes. Up to 2GB officially, 4GB unofficially.

Not graphics card, sometimes the processor although HP are usualy keen on intergrating it onto the motherboard...so in short..NO!

According to my sources a Compaq Presario 4090us is supposed to use an FIC AZ31 motherboard.
FIC = First International Computer, Inc.)

I don't have a motherboard manual available, but MAY have a motherboard layout.

Supporting Data:

Specifications from HP Support: (HP bought out Compaq)

http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00009310&tmp_task=prodinfoCategory&lc=en&dlc=en&cc=us&lang=en&product=92635

1) Processor:
AMD Duron 900
Maximum Frequency Rate: 900MegaHertz
Front Side Bus: (FSB) 200MHz
Voltage: 1.6 Volts (DC)
Wattage used at maximum capability: 36.5 Watts
Part Number: (Top of Processor case. Heatsink, and thermal paste removed)
D900AUT1B

http://en.wikipedia.org/wiki/List_of_AMD_Duron_microprocessors#Duron_.22Spitfire.22_.28Model_3.2C_180_nm.29

2) Ram Memory:
Maximum Total Amount: 768MB
Maximum Amount for EACH ram slot: 256MB
SDR Sdram at 100MHz (PC100)

[Note* SDR Sdram is Single Data Rate Sdram, ram memory. Misnomer of just naming it Sdram is incorrect. All ram memory from SDR up to DDR3, IS Sdram]

3) Harddrive: 30B IDE harddrive. Should be a Quantum Fireball LCT20. (Part Number: QM30000-LD-A)

4) Motherboard Chipset: Sources state that it's a VIA KT133 chipset.
[Chip and Chipset are slang terms for I.C., or Integrated Circuit]

http://en.wikipedia.org/wiki/VIA_chipsets#Slot_A_and_Socket_A

As you can see in the chart reading across from KT133, this chipset supports AP graphics cards that are 4X. Same thing is stated in the specifications from HP Support.

5) The HP Support specifications also state that the mobo (MOtherBOard) has one Primary IDE header for an IDE harddrive, one Secondary IDE header for an IDE optical drive, and one IDE header for a Floppy Disk drive.

Motherboard layout for an FICAZ34 mobo, which I believe is the same, in an additional comment to follow.

No for that model you will need PC2700 DDR SDRAM DIMMs Memory Type

Hello

Yes your computer is compatible with 2GB of Ram.
The second Ram module is located under the keyboard.

Please do not hesitate to let me know if you need any further assistance.

Kind regards

Is this motherboard in a working computer, and is internet capable?
(One never assumes, as the person asking the question, may be using another computer to post the question)

If so, I suggest going to CPUID.com, and download CPU-Z. (It's free)
CPU-Z will tell you all about,

1.Mainboard, (Motherboard): Who makes it, what model number it is, what processor socket it has, what motherboard chipset it uses, what integrated audio, (Sound), what integrated graphics, (Video) (Unless it doesn't have integrated video, and relies on a graphics card), and so on.

2.Ram memory: How many ram slots it has, what ram slots are being used, what ram type it uses, what ram 'speed' it uses, and so on.

3.Processor: What processor is installed, who made it, and what model number, what the Front Side Bus is, (FSB), what the internal clock is, and so on.

Finding the motherboard manufacturers name, and the model number, you go online to the motherboard manufacturers website, go to Support, and type the model number in. This will take you to a Support page for that motherboard. There you will find a CPU Support List, (Processor), plus what the Maximum TOTAL Amount of ram is, and what the Maximum Amount for EACH ram slot is, plus a host of other info.

You can also try downloading Belarc Advisor.

If the motherboard is in your hand, look on the motherboard, and see if you can see the motherboard manufacturers name.
(Examples: Asus, AsRock, Chaintech, Gigabyte, Intel, MicroStar International Inc.,(MSI), ECS, Evga, PNY, PCchips, and so on.

Look for the model number on the motherboard. It may be in-between the expansion slots, near the edge of the motherboard, or in the middle.

If this is a motherboard that came out of an HP, or Compaq computer, things gets a little tougher. Post back here with the computer name and model number.
It's on the back of a desktop computer, right next to the Windows Product Key, or up on the side of the tower.

For a laptop it's on the bottom. It may be in a Service Tag.

Your CPU is tied into your motherboard. Only CPUs that are compatible with your motherboard will work. You can get your motherboard model from start>programs>system tools>system information. Once you have the model # then you can start searching for the CPU options. Good Luck.
