ASUS P5B-Deluxe; Problems & Fixes

[jonny_ftm]

This mobo is a replacement from newegg. Newegg is great for replacement from the original purchase, but replacement don't have warranty and final (no return). So this is suck if I have to go to Asus route. I will try with Asus CD as suggested. Thanks!

If your mb don't even beep, you should have guessed it, the mb is dead. You lost your money changing the CPU, if the CPU dies, the mb still will beep

Oh btw, when I pulled all the rams out (video and cpu intact), the mobo beeps 3x. So it gives a signal and is not dead???

I did swap with working CPU, RAM and video..... and even PSU.

I could be wrong, but, I thought 3 beeps was memory. Have you tried one stick at a time? Still could be the MB. ASUS has fairly good tec support. The PH is posted at Newegg on every ASUS listing.

Also EZ RMA practices.

I decided to start playing with my OC again and now that there are new bioses out for this board I was wondering what the best one is? I am currently on 0804 running an E6400 at 3.0GHZ with 1.2v. Thanks in advance.

You have two options:
3 short beeps
- Base 64K memory failure: A memory failure has occurred in the first 64K of RAM. The RAM IC is probably bad

1 long, 2 short
- Failure in video system: An error was encountered in the video BIOS ROM, or a horizontal retrace failure has been encountered

As you removed the RAM, it is the base 64K memory missing alert

Try removing the bios battery fo some mn, and test with one stick of RAM each time, but sounds as your mb is dieing...

1004 was fine for me for a long time. 1216 has same OC potential as 1004 for me, 1221 too, but 1223 lost my OC.

Once you update to anything 12xx and above, no way to downgrade, even using AFUDOS 2.07: you'll get a CMOS checksome error all the time + OC failure, So, be advised. In any case, if you're looking for only OC potential, give 1004 a try before upgrading above, as they won't give you more headroom

I was happy with 1221 and am going back.

Thanks jonny anc chuckbam. It was actually 1 long, 2 short beep.

I tried your suggestions. Removed bios battery for 5 minutes (got to remove video first). While waiting for 5 mins I tested the video on another machine and works fine. Then insert battery back and video and plug the 6pin video power. Without RAM (only video, CPU and PSU) it gives me 1 long 2 short.

Then insert one stick 2GBHZ, nothing no post. Insert another stick, same nothing. Insert one stick on each slot at a time, same nothing. Can you or someone else intrepret this. thanks!

If my mb is dying or died I will call asus tomorrow monday. Thanks anyway guys!

Try the RAM in another machine, if it is ok, than your MB is dead

[zaina]

thanks, ram is good on another pc so the p5b is dead.

[jonny_ftm]

thanks, ram is good on another pc so the p5b is dead.

If you're sure your PSU and hard disks are well connected, than your MB is dead, I fear too

Hi all,

I have installed G.SKILL 4GB ( 2048 x2 ) and i have the following problems:

*With bios "1101" i get the next results:

- In bios it shows only 3008 MB.
- Under windows vista 32bit it shows 3006 MB.

I think this is not normal

Can you please help?

Go into your BIOS and enable/disable the "memory remap" feature.

What you read by Microsoft is wrong. Vista 32-bit will not read 4GBs of memory, The motherboard needs you to enable the memory remap.

I am happy now ! I am back to Bios #1219.

[allany]

O.K,

I have enabled Memory Remap, but :

-in bios it shows 4096 MB
-in vista it shows 2046 MB

Is that normal?

[MacClipper]

Normal, go 64 bit if you want to see 4GB RAM in both BIOS and OS.

[allany]

Normal, go 64 bit if you want to see 4GB RAM in both BIOS and OS.

With "Memory remap" disabled in bios i can see up to 3008 MB in both ( bios, vista )

With "Memory remap" enabled i can see 4096 MB in bios and only 2048 MB in Vista!!

In Everest it doesn't matter if the "Memory remap" is enabled or disabled, it always shows that the Physical Address Extension (PAE) is Active !!

I mean if you enable the "Memory remap", you should get more memory than have it disabled.

My question is :
Why i am getting less memory with "Memory remap" enabled?

Can you help please

[allany]

Just discovered something interesting with SiSoftware Sandra :


Look under Mainboard->Total Memory , and compare it with Chipset 1->Total Memory

Is that normal!!

Seeking ideas:
I've just upgraded from an E6400 (rated 2.13G) that has been running at 2.975G for some months. The replacement is a Q6600 G0 stepping that seems to hit a wall at 3.024GHz (336 x 9).

After bumping the FSB termination voltage up a notch to 1.4 Memtest passes my Corsair CM2X1024-6400C4D matched memory sticks with the CPU/memory frequency set at 350MHz (running 1:1). Prime95 (v25.5) will run 4 threads rock solid at 336MHz but all 4 cores crash out on the first test at 340MHz.

I've tried raising Vcore by up to 4 notches (it's not a temperature problem - all cores staying below 60C in Coretemp) without success. Have also tried even higher FSB termination voltage, and higher Ich but it just doesn't seem to want to know at 340MHz.

Anyone with thoughts on what to try next?

*************
OK - Problem solved. The key was the NB voltage. I am nervous about this as there is no monitor for the NB temp and I suspect that cooking this was the failure on an earlier P5B board that I had ( that smell - you know the one - and the NB was the only component hot to touch and it was HOT). However, I bit the bullet and upped it to 1.55, and with a couple of notches on the CPU voltage to 1.375 Prime95 has now run through one cycle successfully. A few hours to go before I will be satisfied that it is stable but looking good so far at 350 x 9.

Heads up, another new Bios out. Amazing support from Asus considering the age of this board now

BIOS 1226 (Status Unknown) Dated 11/23/2007, released 11/30/2007

Description:
1. Fix CPU ratio will not reset after load BIOS default
2. Enable support for N/2 Ratio option

ftp://ftp.asus.com.tw/pub/ASUS/mb/so...P/P5BD1226.zip

Comments:
Like a couple others of the latest BIOS releases (1219, 1223), this one also stops in POST and says: Checksum Error, Overclock failed, press F1 to enter BIOS.
I deal with it by entering BIOS and loading BIOS defaults (<F5>), and then reinserting all my preferred BIOS settings. Save and Exit (<F10>).

I had the same problem, for more than 2048MB of memory, you need the Vista 64-bit, Just like XP. Your memory and your motherboard are working fine, You have an operating system limitation. You need to take Microsoft to court for misleading advertising. I was trying to read white papers for days before I went 64 bit.

I have read that anything other than 64-bit decreases performance with 4GBs. not from this link.

I had problems with the last two bios and slowly went back to #1219. It was very painful. I was getting random problem all due to that Dam ATK0110. I find that is the first thing that gives under any stress. I gave up trying to take it off my system a long time ago.

With the Quad CPU I have, the bios posts wrong MHz, but all the utilities show the correct MHz, benchmarks are good and I am rock solid.

What is N/2 Ratio?

I agree, ASUS has done a good job keeping up with CPU support with this board. I have set up a few P35 systems and would replace my motherboard if I thought it was worth the effort. Other than, a small memory performance improvement. I think there is no real reason to upgrade till the new socket comes out and the memory controller is on the CPU. I think that is in Q4 of 2008. And, I may give it 6 more months to make that upgrade. Or, maybe I will not be able to stand it and jump in.

Since this is my main machine and stability is foremost, I just did a little OC today after about a month at stock speeds.

BIOS 1219
--------------------------------------------------------
BIOS SETTINGS
JumperFree Configuration
AI Overclocking set to: MANUAL
CPU Frequency : 333MhZ
DRAMM Frequency :667Mhz
Performance Mode :Standard
PCI Express Frequency : 100Mhz
PCI Clock Sync Mode : 33.33Mhz
Memory Voltage : auto
CPU Vcore Voltage : 1.350v
FSB Termination V : auto
MCH Chipset V : 1.55V
ICH Chipset V : auto
--------------------------------------------------------
It worked the first time. I run FAH SMP and get 2500+ PPD with this machine alone. I'll have to update my sig. . .

At this moderate overclock you should do not need 1.55 for MCH with 2Gb of ram. It runs HOT. Try 1.45v or auto. I would instead set the low end range of your memory stock voltage for 2Gb.
