Please help - board won't boot! PLEASE!

I have built many PCs and have never had a problem until now.

I have the Intel DP43BF motherboard; an intel core 2 duo E7500 processor (BX80571E7500), and am using Crucial RAM DDR3,1333mhz (CT2KIT25664BA1339)

When I start the computer I get 3 beeps; which, according to intel, suggests a memory issue. I have now tried 4 seperate DIMMS (one by one) and none of them have worked, so I concluded it was the board. I replaced the board and am having the exact same problem. I have taken the board out the case to make sure it is not shorting/grounded- it is not. I used the Crucial memory finder to make sure that this memory matched this board- and it does.

I am going insane!!! any help would GREATLY be appreciated!! I have asked tons of people and no one can figure this out!

Here are the product specs:

Removing the ram and getting 3 beeps indicates that there is a problem with the memory. Aside from this it also indicates that the board is probably ok. Testing the ram one by one and finding out that your system does not work means ram problem and not the board. This is confirmed by replacing the board which still resulted to the same problem. Is the PSU adequate? Is the ram voltage requirement properly satisfied in the bios? These are only some of the information that you should check. Others might be the power connectors to the video card (you need one) and processors.

Yes- when I remove the RAM I still get 3 beeps.

The PSU is 430 watts- which should be adequate.

The motherboard supports RAM voltages 1.3-1.65 and the RAM is 1.5. The BIOS is still at all of it's defaults because I have never got to a point where I can even access the BIOS. I get the 3 beeps immediately after hitting the power button- there is no video output.

The video card I have does not required a power connector.

Thanks for the suggestions! Unfortunately I'm still lost :/

Hi,

When you tunr it on, are three beeps one after another, or one then a bit after the next 2? are they all teh same tones?

Do the fans spin up and stay spinning? or do they start and stop?

When you say you have tested 4 RAM moduls, were they all the same make model?

The three beeps are all the same tone and are all right after one another, then a long pause, then the three beeps again- and it just continues to repeat. The fans spin up and stay spinning. The RAM modules were all the same make and model but 4 different sticks.

I'm totally lost :/

Ok, i would def try with another make model of RAM.

Also what make model PSU do you have?

I would prob, just for teh hell of it do a CMOS clear and a BIOS recovery update, see if it helps.

Saying that what happens if you put the board into maintenbance mode does it still give three beeps?

Hi-

Yeah I think I will try a different make/model of RAM- but it's frustrating/confusing because this RAM matches the specs of the motherboard exactly. I used the Crucial memory tool to find it. The power supply unit is a 450W coolmax ca-series. I have tried clearing the CMOS and putting the board into maintenance mode I still get three beeps

yep the first thign to do will be to test anotehr set of RAM.

If that dosen't work, i would suggest testing another PSU, although i doubt it will be that, the PSU only has ATX 2.01... shoul;d prob be 2.2

Also check that teh PSU meets these:

Output Voltage 3.3 V 5 V 12 V1 12 V2 -12 V 5 VSB

 

Current 2.38 A 3.17 A 5.92 A 2.95 A 0.04 A 0.64 A

As i said i doubt it is, but in your situation.....got to try everyhting!

I am having the exact same problem, any assistance would be appreciated.

I have:

Two separate Intel DP43BF motherboards

1 Crucial 2GB Kit # CT2KIT12864BA1339

1 Crucial 4GB Kit # CT2KIT25664BA1339

1 Intel Core 2 Q9400

1 Intel Core 2 E8400

Testing w/ an Antec BP430 430W power supply.

It doesn't matter what combination of motherboard, CPU, or memory I try, I am getting the 3-beep code at power-up.

You'd think that between all these parts I could get at least one working system. Suggestions?

D Jones- if you look on your actual RAM DIMMs there is a product number on it. there will be a long string of characters and then a "." and then 3 more characters. What are the characters after the "."

is it .000? or something else?

Tyler06,

The two DIMMs from the 2GB kit both end in ".4FD", while the two DIMMs from the 4GB kit both end in ".8FD".

The DIMMs are branded Crucial but actually made by Micron. The DIMMs from the 4GB kit contain all these numbers:

On the Micron label:

MT8JTF25664AZ-1G4D1 1024

2GB 1RX8 PC3-10600U-9-10-A0

DPAA8NG002

 

On the Crucial label:

DX111GP.KY

CT25664BA1339.8FD

2GB 240-PIN DIMM 256MX64 DDR3

Okay-

I can't tell you for CERTAIN but this is what happened with me...

I called crucial and explained to them the situation. They had me read them the model number- specifically the last 3 numbers. There are either 8 chip modules or 16 chip modules (i dont know exactly what this means but the support person at crucial told me that this board only supports 16 chip modules which is why mine did not work) I also had the 4 gb kit which ended in .8fd she said the 8 stood for 8 chip- so i am guessing you had the exact same problem as me. When I told her this she said it was not a problem at all- and that she would send me the 16chip version for free if i send the 8chip version back. I would recommend doing that and seeing how it goes. My RAM comes in Friday so I am hoping it will do the trick...

Good luck!

Tyler06,

Please post what happens when you get your memory. I might wait to see what you post before I call Crucial. Need to decide if I want to work with Crucial, or return these to the retailer and then try I don't know what.

According to this page (http://http://www.intel.com/support/motherboards/desktop/dp43bf/sb/CS-031268.htm http://http://www.intel.com/support/motherboards/desktop/dp43bf/sb/CS-031268.htm), the DP43BF supports single-sided 8 chip 1 GB DIMMs, double-sided 16 chip 2GB DIMMs, single-sided 8 chip 2GB DIMMs, and double-sided 16 chip 4GB DIMMs. Which would mean that the 2GB kit I received is incompatible (since they are single-sided 4 chip DIMMs) but the 4GB kit *should* work.

If the 16 chip version fixes your problem, I'll be on the phone to Crucial chop-chop.

tylerl06, Do you have the Crucial part numbers that worked with your board. I am having the same problem and after trying GSkill, and Corsair memory, I would like to get something that works. Thanks.

Experiencing the same issue with:

DP43BF Rev. E78171-303 board,

Pentium Dual Core E6600 CPU, and

pair of 2Gb Samsung 1Rx8 PC3-10600U-09-10-A0 M378B5773CH0-CH9 Comp/2Gb C-die DIMMs;

I believe that memory should run at 1066 in this configuration (as in http://www.intel.com/support/motherboards/desktop/dg41tx/sb/CS-031405.htm# speed http://www.intel.com/support/motherboards/desktop/dg41tx/sb/CS-031405.htm# speed )

Single side 2gb DIMMs are also supported by DP43BF (as in http://www.intel.com/support/motherboards/desktop/dp43bf/sb/CS-031268.htm# dimms http://www.intel.com/support/motherboards/desktop/dp43bf/sb/CS-031268.htm# dimms ).

But I get 3 beeps instead. I have no option to check configuration with another memory, and wondering which I should try to return to retailer - MB or memory.

That memory is not compatible with that motherboard. Neither is defective, they are just incompatible. You can return whichever you prefer and either get different memory or get a different model of motherboard.

Your problem *is not* the memory speed. It is the memory density. You cannot run 2GB 1Rx8 in this motherboard. If you want 2GB DIMMs then they have to be 16 chip DIMMs.

Personally, I would return the memory to wherever you got it from and order the memory direct from Crucial by phone. Make sure to tell the salesperson the exact model motherboard you have and make sure they are aware of the density issue.

I think I have a similar problem. I just installed additional RAM (Kingston 1GB 533 MHz DDR2 SDRAM). I already had a similar 1GB RAM (Transcend 533 DDR2). I am on a Dual Core Intel Pentium D 950 3.4Ghz on a Intel D102GGC2 motherboard. Though my comp recognizes both RAMs if installed individually, it does not recognise both when installed together as 2 GB. Can anyone help?

Dear All.

I just solved same issues. You need 25 minutes, USB Flash, temporary DIMM low size 1Gbit chips and patience. See below how.

REASONS:

1. According to [ http://www.intel.com/support/motherboards/desktop/dp43bf/sb/CS-031268.htm Intel� Desktop Board DP43BF — System memory ] MB supports 4Gb DIMM with 8 chips + 8 chips in 2 sides in total ( 2 Gbit per chip).

2. THE REALITY is that according to [ http://downloadmirror.intel.com/19694/eng/RK_0088_ReleaseNotes.pdf http://downloadmirror.intel.com/19694/eng/RK_0088_ReleaseNotes.pdf ] it works ONLY SINCE THe MOSt FRESH BIOS version 0088 - "Added memory support for DIMMs with 2Gbit SDRAM density".

3. As result in case your BIOS is older than 0088 - you will not be able EVEN TO RUN SETUP of your PC with 4GB DIMM - you will always hear 3 BIP-BIP-BIP. The TRAP 1 from INTEL.

4. Second TRAP 2 is that in case your version of BIOS is lower than 0085 - you will never be able to update your BIOS to 0088 - so, you must update 2 steps - first to 0085 and then to 0088.

5. Third TRAP 3 is that you will not be able to update BIOS from USB Flash even in case you will switch on "USB Update F7 prompt" in BIOS unless you will ensure that your USB Flash stick is formatted FAT32.

SOLUTION:

1. Find at least one DIMM DDR3 where you have 1 Gbit chips. Examples:

2Gb with 8 chips + 8 chips (in total 16 chips in 2 sides of DIMM)

or

1Gb with 8 chips in one side only.

Put given DIMM into your DB42BF and run it. BINGO. It works! But please follow next item.

2. Immediately press F2 and keep it pressed intil you will enter to BIOS Setup.

3. You will see there the BOIS version like RKG4310H.86A.0070.2010.0212.1856 -

 

Here you see 0070 < 0088 = your BIOS doe snot uspport 4 Gb DIMM at all!

4. In separate PC download BIOS 0088 and BIOS 0085 ( in case you have BIOS lower than 0085).

Download area for selection: http://downloadcenter.intel.com/SearchResult.aspx?lang=eng&ProductFamily=Desktop+Boards&ProductLine=... Download Center . You need BIO file like RK0088P.BIO

5. In separate PC also prepare USB Flash by formatting it into FAT32 (all data will be lost) in case yo udo not have it already with such type of filesystem.

6. Put 1 or 2 BIO files into given USb Flash stick.

7. In DP42BF BIOS Setup screen find in Advanced menu the "USB Update F7 Prompt" and set to ENABLE.

8. Insert USB Flash stick with BIO file(s) into USB socket of DP43BF.

9. Save and Exit BIOS setup.

10. Press F7 and keep it pressed until you will see the UPDATE dialogue.

11. In case your BIOS is lower than 0085 - first select it for update and pass the update, then repeat again the F7 and update for 0088.

12. Now switch off PC. Remove temporary memory. Insert 4Gb memory DIMM(s). Run PC - BINGO - it works.

Little more happiness: your MB now supports even 16 GB (they forgot to mention it in specification as well).

Enjoy using INTEL - I just battled, discovered and passed all above nighmare myself. Successfull.
