Question about AOpen AX4PER 845PE P4-533MHz DDR333/5.1/AGP4X/LAN/ATX Motherboard

3 Answers

Ax4per with 1.8GHz does not recognize new 2.8GHz processor. Socket 478. BIOS is current. Is it not plug and play?

    Thanks. MoBo is jumperless,and AOpen says it does. perhaps the CPU is DOA.

  • scotdonovan6 Sep 10, 2009

    Hi Wayne, I do have that PDF file. I will follow the steps you listed and tell you what happens.

    The system does not POST, the CPU fan comes on, but then nothing. When I swapped the old CPU back, I found that the NEW CPU did not generate any heat at all.

    I am able to access BIOS every time the 1.8 CPU is in.

    The new CPU is INTEL P4 2.8 GHz 1MB 533 478 Desktop CPU SL7E2.

  • scotdonovan6 Sep 10, 2009

    I notice that Core voltage is 1.25 - 1.4. With the 1.8G in, BIOS is set to 1.75v. Should I lower it, then shut down, install, and restart?

    Reset CMOS. Still no POST. I'm going to try another CPU. The specs from Intel say this CPU SHOULD work. Tomorrow I may try booting with the 1.8GHz into BIOS and manually setting. I think I tried that already, but I'm kinda blearry eyed.

Hi,

Does it POST and can you get into the BIOS? You need to set the FSB to 133MHz and the Ratio to 21x.

(I am assuming you did install the CPU correctly and installed the fan.)

If you can't get into the BIOS, you may need to reset it using JP14 on the motherboard.

Turn OFF power. Remove the AC power cord. Hold the power button in for 5 to 10 seconds. (This is done to discharge any capacitors.) JP14 normally is on Pins 1 and 2. Place the jumper on Pins 2 and 3 for approx. 10 seconds. Then place it back on pins 1 and 2. Connect the power cord and turn it on. This will set all the BIOS settiings to default and you should be able to set the FSB and Ratio.

Do you have a manual for the MB? you can get it from:

ftp://ftp.aopen.com/pub/manual/mb/ax4per/ax4per-ol-e.pdf

Thanks for using Fixya.

    That link for your manual is messed up. (Thanks Fixya!)



    Try this one:



    ftp://ftp.aopen.com/pub/manual/mb/ax4per/ax4per-ol-e.pdf



    Wayne



    BTW....Yes your MB should support a 2.8GHz processor. That is the max though.

  • Wayne Mineard
    Wayne Mineard Sep 10, 2009

    OK. Fixya insists on putting a prefix on ftp links. Grrrrrrr!



    If you click on the link, you will get a "Page Not Found". Just delete the "http://www.fixya.com/" in the url and hit Enter or GO. That will work.



    Sorry for any confusion.

  • Wayne Mineard
    Wayne Mineard Sep 10, 2009

    If you reset your BIOS, I'm not sure what the defaults will be for the CPU. For the 1.8GHZ the FSB is 100MHZ and the Ratio is 18x.

  • Wayne Mineard
    Wayne Mineard Sep 10, 2009

    Actually your MB is supposed to have a voltage auto-detect system.

  • Wayne Mineard
    Wayne Mineard Sep 10, 2009

    The specs say the SL7E2 is a 533MHz FSB processor so yes, it should work.

Your board has a 533 mhz FSB and the Pentium 4 2.8Ghz uses a 800 mhz FSB. The socket for both chips are the same but the FSB is different speed. You will need to upgrade *********** board to a board compatible with a 800 mhz FSB Like the one on the link. It has a 533/800mhz FSB. Yours only has 533mhz.

Either it does not support this speed or there is often a jumper setting on the mobo that allows you to switch to different speeds. Try changing the jumper (if available), but most likely the mobo does not support this CPU.

How many processors supports my motherboard p4m80-m4 biostar ? specially can it support dual core processor...??? also tell me about supported graphics card please help me>>>???


You have a very old motherboard here. It only supports the older AGP 8x video cards. Good luck finding one of those anymore that is worth the price, and don't expect anything you find to be new in box. This is probably where your HD video woes start, although the board was never designed for the higher frame rates that HD requires to be viewable.

As far as the processor goes, this board has the Socket 478 for Intel processors. There are no dual-core processors that are supported by this socket. Here is a link to an article that shows what processors are supported by the socket. Be advised, however, that depending upon the BIOS revision on the board, some of these may not work properly, if at all.


Socket 478 Socket mPGA478B


Really, if you want to view HD, it's time for a real upgrade.

Pls provide new processor's will match KOB 845GL NDSMx board


It uses a Socket 478 for an Intel Pentium 4 processor up to 400MHz. You are somewhat limited being this a older (in computer yrs) model. This is the fastest and for some reason the cheapest I could find.

I need to know what kind to buy for this board. the processor heatsink ASRock ge pro-ht


Socket 478 is a very old socket type, it's been around for nearly a decade. The only processors that work with this socket are Intel's Northwood Pentium 4 and Celeron processors, which are now far surpassed in performance. I would definitely recommend buying a new motherboard for whatever you were going to use this one for. If you are set on this motherboard, however, read on.

Many computer hardware companies have stopped carrying Socket 478 processors. You will most likely have to buy one second-hand. A quick search on Amazon will give you a few buying options (all used) for around $20-$30 US.

Due to the age of the processors, you will probably need to purchase a heat sink seperately. This heatsink is $20, will fit Socket 478, and has very good reviews, but of course feel free to use any heatsink as long as it fits Socket 478: http://bit.ly/hk6yZ5

If you also need memory, be sure it is DDR 333/266, as this is the ONLY type of memory that the 2 memory slots on motherboard will take (maximum 2GB of memory). You can find list of DDR 333 memory in varying capacities here: http://amzn.to/fOGbeV

Right i need the size or model for the cooling fan that all intelboard mode E210882


The Heatsink/Fan combo is based on the processor socket used.

After a few search hits, I have seen E210882 on Intel based motherboards, that use two different processor sockets.
The Socket 478, and the LGA 775 processor socket.

The socket for the Socket 478 has the pin holes. The Processor has the pins. (478 of them)

http://en.wikipedia.org/wiki/Socket_478

The socket for the LGA 775 processor socket has the pins. The Processor has the pin holes. (775 of them)

http://en.wikipedia.org/wiki/LGA_775

Identify which processor socket you have, buy accordingly as to the Heatsink/Fan combo.

One example of a Heatsink/Fan combo for an Socket 478 processor socket,
(Only Intel uses the Socket 478 for their Processors),

(Only Intel uses the LGA 775 socket for their Processors),

http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=3302824&CatId=1588

Remember to observe Anti-Static Precautions, Thoroughly clean the top of the Processor's case, and aplly fresh new thermal paste.
(A Processor is the most susceptible hardware component to Static shock)

[ Example of thermal paste,

If you would like advice on how to properly clean the processor's case, properly apply thermal paste, and/or what Anti-Static Precautions are, post in a Comment.
