i've had mine a good while now.no major problems apart from 1x pci-e.both lans work fine and i've had it to windows at 560fsb.i'm running it at 500fsb for 24/7 with no problems.
i find it to be a reliable fast board.sorry about other peeps probs tho'
I kinda did something to my bios while overclocking a tad too far. Started to post and froze. I had to turn the PSU switch off in the middle of posting. Things got all funky after that. I think something in the bios got pooched cause I had to shut it down like I did. I still had the 804 bios on my USB stick and reflashed. Everything was fine after that.Quote:

EDIT- Page 4-8 (section 4.1.5) in the manual..... Asus CrashFree 3 Bios Utility. It's exactly what I did... without even reading the manual:)
Wouldn't that be refreshing.Quote:

p5b-deluxe E6400,2x1gig Gskill ddr2 800 GBHZ mem, powerstream 520,8800gtx,
the problem is i oc'd to 3,2 gig started runnibg super pi in 16kb test half way into the test it shot down i reset the cmos i did it all night when i turn it on the machine comes on the fans everything the lill asus light is red too but nothing on the monitor!
I have the latest 804 bios too!
what it does when i start it, it starts few sec later beep and restarts and stays on but nothing on the monitor! I noticed when i turn it on everything is fine than it takes 6 sec.(fan wont start right away)the vid card fan speeds up and right away beep and restart and after that it starts up again but the vid card speed is up but no pic on the monitor!
PLEASE HELP me fix it!
Try one stick of memory in the yellow slot ,the one farest from the cpu.Quote:

Unplug it for 10+ seconds. then restart, the bios should be reset to defaults at that point and restart. if that doesnt work, clear CMOS and reset.
This has happend to me and the 10+ sec reset works every time.

If still nothing try below one at a time:
Unplug all your drives and pull all the other add on cards.
Try moving your video card to the other slot. Make sure video card power is connected/reseat.
Try reseating the power cables to the MB.
Try a different video card.
Try another power supply if you have one.
thx guys for help but i tried it all and still nothing! im pulling my hair! i will RMA it!
would the gigabite or the evga board be better?
I have the same MB and RAM.
It's not the MB it's the SPD in the RAM not letting the MB POST.
Try a diff stick of RAM. Manually set timmings and VDimm to 2.3v.
Save, powerdown, install GSkill, boot.
Mel
I can not speak for the evga board, but the Gigabyte DS3 and most boards that use Realtech onboard audio, they do not reproduce EAX audio properly. If you are not using on board sound, then it is not a problem. I had a DS3 before getting my PB5 and can say that it is a great board for the $.Quote:

they don't even do EAX. its a scam. maximumpc wrote a article on this, using rightmark software to test.
Doesn't that ram use Micron D9GCT (B6-37E) or Micron D9GMH (B6-3)? They should boot with 2.0V and default BIOS settings as far as I have heard.Quote:

My Crucial Anv. Ed. uses D9GMH and had no trouble with booting at default voltage and BIOS settings, until the board crapped out.:) Just a thought....
I have a problem, sone day ago i flash the bios of my p5b deluxe, i mount 0908, the problem is that i want to go back to 0711.. but de asus flash utility don't allow me go back. How i can go back, because some people said me that 0711 is more powerfull than 0908 it is correct?
Thank for all and sorry my english
go to AsusUpdate---Options----donwngrade bios enabled. that's it.
Thanks man!!! i'm going to try...Quote:

with zalman CNPS9500LED....
With that config the system boot but if i put more than 500 FSB no boot... in winXP with clockgen i get 516 FSB :d

I have a possible prob with my P5B (bios 804). I've installed a OCZ XTC mem cooler and would like to regulate its fan through Q-Fan (installed on cpu header). However it doesn't work. XTC cooler utilizes a single 3pin connector for both fans.
Does it require a 4pin fan for Q-Fan to work on cpu header? :confused:
I'm @ wc'ing for quite some time and haven't used Q-Fan.
For some reason I cannot even get my system to run at 400x8. There's no post. Before I changed the stock fan to a TTBT VX, it would boot to Windows & ran Orthos for about 5 seconds before the system halted. So I know it can get there but for some reason after the HSF change it won't post at 400. The power needs to be switched off at the wall for a minute or 2 before the system posts with the OVERCLOCKING FAILED message. Temperatures are very good and the HSF is mounted properly.
What is the procedure to ensure the system will post at 400x8 1:1 if my previous settings are 333x8 1:1?
Using BIOS 7/11 at the moment
Current 333x8 settings:

All memory timing settings were left alone.
Are the voltage settings wrong? Or are the FSB & PCIe frequencies wrong?
System specs are below in my signature. Any help would be appreciated!
try 401 instead of 400 it will change the nb strap but should boot.
Utetopia - your subtimings are wrong. I guess this is an issue with brands other than Corsair. When you switch to manual the BIOS does not put the correct subtimings in - you have 10-10-10 in there.
use Memset and get the correct subtimings.
See my post in this thread.
Ah the 1333FSB strap. Thanks a lot! 401 worked first go and the system loaded perfectly! Once it got to Windows I opened CPU-Z then the system had a freeze but the mouse still moved. Had to hold the power button to shut it off then went to BIOS to check the volts. The RAM voltage was at 1.90v but a little boost to 1.95v seems to have fixed the freeze up. Orthos is currently up to 1 hour of blend & running strong! CPU is at 1.3875v with Windows showing 1.360v.Quote:

First things first, time to drop the CPU vcore & see how far it can go down before it freezes. :)
So 3-11-5-14 instead of 10x4. The other subtimings are @ 42 & 6. SPD in CPU-Z says I should use 35 instead of 42. From what I can remember, they are the only 2 choices for that option.Quote:

Orthos failed at 53 mins. Not enough RAM voltage? 1.95 too low? After a bit of reading up 1.80v is apparently enough. It's even possible to do DDR1000 @ 5-5-5-15 timings with only 1.80v.
I have my memomy @ 800Mhz 5-5-5-15
but my first bootscreen called it PC-4300
What's my problem here? Do I have to worry about it?
That's no problem, don't worry.
Hi I saw your ocau post as well. btw the vdimm required wont be the same for all modules anywayQuote:

I have Windows XP SP2. I've read that I don't need to press F6 during my install for my Sata drivers. Is that true? :confused:
If not then where should I go to download the latest Sata drivers? I can't find them on Asus website and Seagate didn't have them either. So I'm not sure where to find them.
And lastly I'd just like to install this hard drive non-raid for now. Should I choose Intel(R) 82801HR/HH/HO SATA AHCI Controller (Desktop ICH8R) for my install?
^^You shouldn't need to install any F6 drivers.
Kumakichi
For RAID or AHCI in BIOS , you need F6.
Asus CD has option to create diskette for Intel and JMicron.
However, If you want plain SATA/PATA than its IDE in the BIOS. No need for F6
AHCI gives NCQ feature. Once you have the Intel diskette or Jmicron , its easy to try AHCI with the HDD.
As for Sound Card. Wait untill you have your PC running and experience with the ADI SoundMax.
JoeBar
Intel's 4pin header is a headache for me too, unfortunately.
3pin, or in my case, 2 pin , can't be controlled with just plugging them in. My fan works at 100%.
In your case an easy solution would be to use the chasis headers. they all work in unision
utetopia - your mileage may vary. CPUZ-ID and Memset should be reading the same thing - if they're not you'll have to experiment. iI don't know which is more accurate. But I can tell you 42 will be more conservative and probably not make much difference in real life performance. try bugging micron for the subtimings too.
in any case the timings I posted were for Corsair 6400-C5 ram, subtimings depend on the actual ram chips the manufacturers use, you might try posting in the bandwith forum to see if anyone knows. I know you can identify Corsair RAM chips by the revision (the sticker on the heat sink) as they do post the exact chips used by revision in the Corsair houseofhelp.com forums.
anyway you should be able to clock higher now - i can't believe i was running for 3 months with bad subtimings. I was stable at those speeds in Orthos for four hours, but then when I read about it and ran Memtest to check I got memory errors after one hour. With the correct subtimings I have run Memtest 8 hours with no errors and can clock higher.
Thanks for the reply :)Quote:

The board seemed promising though, i was able to get it to 530mhz on air. 6x multi just for testing, it looked like it was going to fly under phase but i didnt even get that far.
forget what pass experience you had with another board...anytime you switch boards, you start anew!
try taking it down to one stick of memory and also using a PCI video card....you might need more than 1.8V for Vdimm voltage
I've tried all of that and this same memory has booted up just fine on other boards that default to 1.8v on initial boot. I wish i had other memory to test but i dont and i dont think thats the issue. The same memory worked fine for 2 days and is still working fine right now in my aw9d-max.
I also dont have a pci video card to test with and dont think i should need one to get a board to run stock. My question was directed at those that have experienced the same issue with this board. Is there a fix or did you guys just rma?
MrDeeds :
Its dead. Unless its the PSU
If cpu/ram/video , i.e basic , minimal , won't boot ...
P5B Deluxe is one of the best there is atm. It has its quirks - audio crackling, all Cha Fans work together Only, and few others. And you got excellent OC results. There you have it.
Kumakichi :
NCQ brings few %. Google for that.
I've never used it. But you may have problems if you change BIOS to RAID, or add inferior HDD.
I would try NCQ , but create image file after I've finished setting my OS up.
Thats always a good idea :)

************************************************** *******************************************
FAQ :
PCI-E 1x Link Width issue :
Happens when OC-ed. After restart link width is automaticlly set to 1x instead of 16x, which causes significant performace downgrade. Reason unknown. Happens mostly with ATI GPU cards. Possibly a BIOS protection measure, preventing percieved possible damage to GPU or motherboard, or a BIOS problem with proper video card initaition.
Symptoms :
PCI-E Link Width switches from 16x to 1x after a restart.
Solution :
- Unplug PSU, wait a few seconds, replug PSU.
- Unplug PSU, reset CMOS, replug PSU, renter all BIOS settings, save, shutdown, power on.
- Combining slightly lowering or uping voltages of PCI-E, Vmch, VCore and FSB can usually fix it. Also try
disabling ASUS C.G.I and PEG Force 1x., and changing values to PEG Link Mode.
- Flash to BIOS version 0711, then reflash to 0804.
Issue regarding insufficient default vDimm value for some higer voltage rated memory sticks :
Symptoms :
Not being able to cold boot, or motherboard giving memory error beeps.
Solution :
Use a 1.8/1.9 voltage rated memory stick, to boot in BIOS. Then change the vDimm value to hardware specification of your memory sticks. Save BIOS and immidieately unplug PSU, not giving the motherboard time to boot, hence preventing the lover voltage rated memory to recieve excessive voltage. Replace the memory. Power on.
Onboard sound card issue :
Possible symptoms :
1) Optical cable sound distortion
2) Sound distortion and cracking/popping-like sound within OS and while running games.
3) Slow OS boot time.
4) Lower OS and HD performance, response times, and micro freezeups.
5) No sound on 2 rear speakers.
Solution:
1) Keeping your onboard card enabled (Might not solve the issue) :
- Update to the latest drivers.
- Set your speakers to 'Large Speakers' in the preferences of the SoundMax utility.
- Disable all DTS and digital output related options.
- Put PEG link value in BIOS to Normal.
- Disable the HD AUDIO in BIOS to achieve faster Windows boot time.
- Try using Microsoft’s BootVis utility to speed up Windows boot time.
- Put Windows sound sheme to “No sound” in “Sound and Audio Devices” located in Control Panel.
2) Disable onboard audio and use a PCI sound card. Resloves issue 100%. (if drivers have allready been installed, a new OS installation might be required, as some issues still remain after uninstall).
FSB wall issue :
Can be due to improper voltage settings, or CPU, memory or motherboard's inability to achieve higher FSB.
* All hardware components are unique, and therefore have unique propreties within, and possibly out of hardware specifications. Also there is a hypotesys that motherboard cannot boot at certain FSB speed due to strap settings.
Symptoms :
Not being able to OC over a certain FSB setting either by computer not being able to boot or being unstable when tested.
Solution :
1) Experiment with voltages (and other BIOS settings), by sligtly increasing them, and restesting after every change.
2) Try increasing the FSB speed by larger increment (e.g. try going directly to certain FSB setting that is not influenced by the strap issue – 400, 500,...)
3) Narrow down the problem to a single component, and try to replace it with other, same component, or newer.
Jmicron controller issue :
Symptoms :
Slower HD speeds then rated, slower HD response time, reading/writing issues with ATA Optical drives, high CPU usage.
Solution :
1) Try installing latest official drivers
2) Try installing latest beta drivers.
3) Disable Jmicron controller in bios
HDD shutdown at reboot or in Windows: Install latest Intel Matrix Storage Manager .
Double restart issue (Ghost start) :
Starts happening when FSB is raised (usually around 400 MHz).
Resolved from bios version 0804.
*Double restart after changing FSB in BIOS is normal behaviour, due to BIOS NB strap changing.
Wrong Memory SPD detection issue:
Happens when manual option is enabled in bios. In which case manual adjust of BIOS memory settings is nessessary for proper functioning.
1) Corsair Twin2x2048-6400 : 5-5-5-12 - 5-42-3-11-5-14
"Unknown Device" in Device Manager :
Install the ACPI driver for ATK 0110 virtual device either from ASUS CD or by dowloading it from X/misc/utils/ACPI_10136.zip.
Vdroop issue :
Symptoms :
Voltages that the components are reciveing are lower then set in BIOS. Also drop in voltage or voltage fluctuations are noticeable durig testing/stressing of system (e.g. using Orthos to see maximum Vdroop).
Solution :
Vdroop of up to 0.1v is normal for ASUS Intel-based boards. Any higher Vdroop is reason enough for RMA.
1) U can stabilise the system by raising the voltages in small increments.
2) To be able to achieve motherboard giving exact voltage to components as set in BIOS vMods are nessessary (Caution : Vmods void guarantee).
*Note : The only valid way to obtain voltage readings is by using a multimeter .Windows based programs can sometimes display inaccurate readings, esspecially when system is OC-ed. On instructions how to use a multimeter read this tread - http://www.ocforums.com/showthread.php?t=403837
Additional notes / warnings :
1. CMOS clear and Chassis open detection jumper are really near. So watch out not to mistake them.
2. When doing an OC, never leave any value in BIOS at AUTO value, always set everything manually. First, by setting them according to your hardware specifications, and if the settings prove to be stable, work your way up from there. Or if you don't know the values, you can see your default (auto) values, from within windows. After the values observed are inputed in BIOS, go to windows and observe if the values read with this manual setting are exactly the same as when the auto values were used. If they are not, change accordingly.
3. Several people have reported USB issues, ranging from freezing up of system, to low response time and detection of USB devices. No solution known.
4. It is needed to load RAID drivers for SATA discs, during windows install even if RAID systems will not be utilizied, or a single disc is used, to be able to use full benefits of AHCI. This can be done in 3 ways :
a) By pressing F6, during install, and supplying drivers via floppy disc
b) By slipstreaming the drivers into a Windows installation disc, prior to installation.
c) If you have allready setup your instalation of Windows without using the first 2 methods. Instead of reinstalling the system, go to device manager and update the ide controller that's connected to SATA drive. Make sure you force it to select “Intel® 82801FR SATA AHCI Controller”. Restart, and go into BIOS before Windows starts and change 'RAID/ATA' option to 'RAID/AHCI'. Boot into Wndows.
5. Do not update any drivers trough Windows Update.
6. 1:1 is the lowest divider on 965 chipset. Best-buy sticks for this motherboard, are those whose speed = 2 x FSB speed.
7. Several users have reported that motherboard’s PCB was covered with saltwater-like destilation residue (some grey “goo”), althought it is directly out-of-the-box. Reasons not known. No known sideaffects.
8. For dual-channel mode use same color slots (A1 – B1, A2 - B2), or different color slots, by placing one stick in first 2 slots, and second in second 2 slots.
9. The SB heatsink has a bent pin. Can be easily straightened. Possibly a manufactoring process error. No known sideaffects.
10. Do not install any of ASUS programs from a CD that is supplied with motherboard unless absolutely nessessary.
11. All Intel CPU’s Conroe core have a FSB wall, that prevents from reaching higher FSB speed. Also they can sustain core voltage up to 1.7v. They automaticly shutdown at 85 °C. Best OC pieces are marked week 29, revisions B and C.
12. Memory frequency is more important then timings, so if timings must be sacrifised to obtain higher frequencies, make it so.
13. You can have a front panel "headphone/audio out" that is on an entirely separate channel (as new device). This is enabled from SoundMax preferences.
14. When System monitor option is clicked, system freezes for a few seconds. That is normal for this motherboard, since by design flaw, longer amount of time is required for BIOS to read FAN speeds.
15. Select "S3 only" setting to shutdown fans when entering in suspend mode. Also, if left to AUTO, when system is OC-ed it will reboot when coming out of suspend state.
16. Setting PCI-E frequency to setting higher then 120 MHz will cause disconnection of SATA drives (probably due to chip going offline).
Flashing BIOS :
When flashing BIOS use the following procedure.
*) Write down all BIOS settings relevant to OC. If your computer is OC’ed, set all options to
stock/spd/hardware/default settings.
a) Load Optimised Default settings option, save BIOS settings(F10)(computer will restart).
b) Save current BIOS to a file.
c) Update with new BIOS, restart computer.
d) Load Optimised Default settings option, save BIOS settings(F10)(computer will restart).
**) Renter OC settings that u have written down.
***) If system shows instablities with same settings, try modifying settings, primarily by lowering and uping voltages. If nothing works, reflash with previous stable BIOS following the same steps.
CLEARING CMOS :
*Note: Turning off the PSU is mandatory step before trying anything
1. Connect pins 2/3 with a jumper for 4-5 seconds, then return jumper to previous position.
2. Remove the CMOS battery, connect pins 2/3 with a jumper for 4-5 seconds, return battery, return jumper to previous position.
3. Remove the PSU motherboard connectors, remove the CMOS battery, connect pins 2/3 with a jumper for 1 hour, return battery, return jumper to previous position.
4. Remove the PSU motherboard connectors, remove the CMOS battery, connect pins 2/3 with a jumper for 24 hours, return battery, return jumper to previous position.
5. Remove the CPU, unplugg any SATA/IDE devices, plug in PSU, turn on the power a few times (e.g. tapping the power button a few times), unplugg PSU, reseat CPU and reconnect unplugged devices. Repeat the procedure a few times if nessessary.

________________________________________
Simple guide to help get you set up and start overclocking your P5B motherboard.
Things not covered are sound, usb etc as they are enabled as users need.
BIOS
Bios 0710 or later should be used. for this guide I am using 0711. Grab it here If you have the wifi version of the board make sure you download the version of the bios you need.
Some helpful tips.
it seems Asus have a little known tweak that resets the board. Basically all you do is power on the board with no CPU for 10 seconds and this resets the board to factory defaults. If you have a none boot for some reason this may be the fix you need.
Moving to the bios an explaination of the options and what to look for.
Advanced section options, all we are bothered about for overclocking is Jumper free configuration, CPU configuration and chipset.
You open Jumper free config and this is what you get.
Next option to look for is AI tuning, this is where the overclocking starts.
Set this to manual, this open up the bios still further.
Working down the list you will see:
CPU Frequency, once chosen just use the + or - option on the numeric keypad to push the FSB up for down, the limit is shown top right of the bios screen and is 100 to 650fsb. Real limit for most boards dual channel is 540ish at this time.
DRAM frequency is where you choose what speed the ram will run at, on the P5B this is directly linked to the CPU Frequency, so as you push up the CPU fsb the Dram frequency pushes up with it...a nice touch from Asus.
I have decided to explain the DRAM ratio's further into the artice so now we move onto:
PCI Express frequency.90 to 150MHZ is selectable, selecting 120 or so can add a healthy boost to PCIE bandwidth if the cards you have can run this frequency. This option needs to be tested thoroughly to see how much the video cards can stand.110 is usually very safe, 120 is starting to push it a little.
PCI Clock...just set this to 33.33 and forget about it.
Spread Spectrum is best disabled for overclocking.
Memory Voltage 1.8 to 2.45V, only supply the dimms the voltage they need to get the overclock or speed stable. I recomend no more than 2.5V for DDR2 maximum and with this board hitting 2.45V max you should be safe. Remember to cool the ram with a fan if you can.
CPU Vcore Voltage Auto sets the voltage the CPU is hard coded to set, I always set this and view the voltage in the hardware monitor section of bios so I know my start point. Remember more volts = more heat, on air cooling with C2D try to stay at under 1.5V, 1.6V with water and phase change cooling.
FSB termination Voltage useful option when pushing the FSB frequency high on the CPU, adding a little voltage here can help stabalise things as you clock higher.
NB Vcore Remember the memory controller is on the NorthBridge, adding some voltage here can have a huge impact on how well the CPU and memory overclock. Just remember if you set the max 1.65V to keep the NB cooled by adding a fan over the heatsink.
SB Vcore useful for adding extra voltage to the PCIE bus when overclcoking video cards and trying to run them on an overclocked PCIE frequency, I would tend to use 1.7v as a max here.
ICH chipset voltage I have found no need to alter this during testing, some say it adds stability, I set auto.
CPU Configuration page. I scrolled this down so you can see all the options in the pic. For overclocking you may want to drop the multiplier on the CPU an option or two, highlight the Modify ratio option and you see the following.
Now, not all C2D's are fully unlocked, some are partially unlocked so to see what you have available to tweak I highlighted where to look.
Remember to also set the following if you are adjusting Vcore and the ratio on the CPU.
Moving on its time to look at Northbridge Configuration
Once you enable this page you see the following.
The memory Remap feature is for when you are using 4GB of stsrem memory and XP, this option hardware maps the allocated ram from just over 2GB to just over 3GB with good performance, if you have only 2GB installed just leave this to disabled.
Configure DRAM timing by SPD if you leave this option to auto it will read the timing tables off the modules and apply them to the memory during normal operation, issue is we have found Asus force a few timing options of their own and only partially use what is coded into the SPD, this is why we always recomend end users set their memory timings manually. To do this force the SPD option to Disabled
Once Disabled the page opens up to reveal the following.
Most everything you need is included, the following pics reveal all the options and where to look for the options available. Some require you to select the option and choose from a list, some require you just use the + - options once the field is highlighted.
Remember to initially set the default timings for your modules, usually manufacturers quote the timings in the following order...tCAS, tRCD, tRP and tRAS IE: 5-5-5-15. This just so happens to be the order of the top 4 options in the Asus P5B bios, so if you are unsure just work down the list setting what you see quoted on the dimms and you will be good to go.
Dram Write Recovery time 6 is ultra lose and good for high memory overclocks, 4 is about as tight as most dimms will go, keep this in mind as you test.
DRAM TRFC simple rule for this option. If your memory is Micron IC based you may be able to go as low as 20, everything else we have found 35 works best. Options are 20 25 30 35 and 42. obviously 42 is very lose and will allow higher overclocks.
TRRD Options 0 to 15, around 10 is where most leave this, no big effect on performance.
Rank Write to Read delay Real important timing, start at 10 some dimms may even need 12, tigher for more performance.
Read to Precharge delay again important timing, start at 10 with some dimms needing 12, tighter for more performance.
Write to precharge delay again another important sub timing, same rules..start at 10 or 12, tighter for more performance.
Static Read Control Disable for moderate to high overclocks.
Little further down
PEG Link Mode has a huge effect on video performance, I personnally leave to Auto, Fast and Faster for the brave.
Asus C.G.I if you are running Xfire (maybe SLI also) you need to enable this option as it looks to enable Peer to Peer writes which allows the Video cards to talk to each other.
last but not forgotten, South bridge chipset Configuration You are going to want to set 4X mode for best performance if running SLI or Xfire.
Memory controller issues you need to know.
For the i965 chipset to stand a chance of hitting high FSB speeds some clever manipulation of the chipset internal timings are needed. Most know Intel release CPU's with various default FSB speeds, the usual suspects are 533, 800 and 1067. Celerons are usually fixed on the 533 bus but should be moving soon to the 800, most other P4 775 CPU's are 800 bus speed apart from the older Extreme Edition and the new C2D CPU's that are based on the 1067FSB.
The CPU has a set of pins or dots on the base called the BSEL . These pins or dots actually tell the board what FSB to apply to the CPU and tell the chipset what strap to run. The strap is actually a set of ram ratio's and a clock muliplier along with an internal latency setting. Try to think of the northbridge pretty much like a CPU...it uses a default frequency and a muliplier..and yes you can overclock it.In difference to a CPU though it also controls the memory and as such has internal latency settings that can be changed also.
Now....what you have to remember is as you push up the FSB on the CPU you also push up the FSB on the chipset. By default the chipset hits its max clock way before the CPU does...so what do you do?
The answer is manipulate the chipset into thinking it is working with a CPU that has a higher FSB default speed.
How this is done is by altering the BSEL signals the chipset uses and by setting the undocumented(at this time) 1333 strap...this means the chipset thinks it is working with a CPU that has a base FSB speed of 333 (quad pumped is 1333)
Now Asus have been quite slick with the P5B range of boards as they allow the chipset to overclock quite a bit before they slow it down by altering the strap, what this means is that once slowed down by the 1333 strap it is already in an overclocked state. The bad part is that between 360 and 399fsb the chipset is massively overclocked and really does struggle some what, the consequence of this is an "FSB hole" where it is hard to get the board stable. In reality all you have to do to avoid this "hole" is set 400fsb or higher as the strap changes here to 1333 and the board takes off again usually all the way to 500+FSB. I explain more on what exactly is happening here in more detail.
What would be nice is the 1333 strap coming in at 360FSB but with the internal latency set using the 1067 strap which is faster than the 1333 latency setting, this would allow the board to work well up towards 399FSB.from 400FSB you would relax the latency setting to the 1333 default and allow the board to clock all the way to 500+ without the non usable hole we see at this time. hopefully if Asus see this article they will tweak the bios to set more like what I have quoted...but for now the board is an awesome overclocker as it is by default but it has this 1 quirk.
Memory Ratios
Default ratio's on the P5B range of boards, I added a small table along side the available options explaining how these ratios are made available.
Default 1067 strap has the following option available.
533,667,800 Or 1:1 (Sync with CPU FSB) 4:5 (async upclock) and 2:3 (async upclock)
By strap manipulation Asus have managed to add 2 options from the 800 strap which are 889 and 1067. 889 is 3:5 (async uplclock) and 1067 is 1:2(async upclock)
All should work fine with the CPU at default speed, the issue is they work very differently once you start overclocking.
If you are looking to run high FSB speeds then you really do want to stick with 533 or 667 mode. 800 will push the ram speed way to high normally.
If you are at stock speed you may want to try 889 or 1067, the reason for this is that these ratios are based off the 800 strap so the chipset is already running faster than it is when using the default 1067 strap memory ratio options. The downside though is the chipset will in no way overclock as well, infact some are right on their limit trying to run the memory in 1067 ratio and will error quite bad. 889 though is quite nice and does allow for some moderate overclocking. With the chipset running overclocked and a moderate overclock on the CPU you may find you have a wicked fast system, just remember we are not talking huge FSB speeds though...using a dram ratio taken from the 800 strap you are limited to moderate CPU and memory overclocking as the chipset is already overclocked with the CPU at stock speed.
There is 1 last tweak to be aware of...Often known as TURBO mode. Turbo mode takes chipset overclocking to the max, on a board like the P5B deluxe it would only run at the CPU's default speed. Turbo mode would involve forcing the chipset to run the 533 strap with the memory in 1:1. Using memory that is capable of tight latencies at DDR533 you would see performance from the board as if it was running memory at DDR1000 or higher. This would be due to ultra tight 533 based chipset latency and the fact that the memory controller would be massively overclocked.
The only downside is Asus usually limit this mode to default CPU speed, as soon as you set 1FSB over default the option turns its self off.
At this time I have not seen Turbo mode in the P5B bios, would be nice to see it appear soon though for the non-overclockers looking for a little system performance boost
I hope this small guide has been helpful, more guides are on the way as time allows, and board manufacturers send me boards (shamelss begging!!)

Anyone having trouble running crossfire with 2 X1950 Pro? I see results here at XS of people running it but the official word from the Asus support was that the P5B DLX dosen't support crossfire with the X1950 Pro cause the 965 chipset doesn't have support for internal writes?
So anyone know for sure? Maybe I should mention that I can't get it to work with my board + 2 Sappgire X1950 Pro, other then run a few runs in 3dmark. In games it's a total no go. Tried cat 6.10, 6.11, 6,12.
Many thanks again Ancient1 for taking the time to reply. I did a lot of digging and found some interesting posts.Quote:

Maybe after awhile I'll switch to Vista and try out NCQ.
NCQ works just fine in XP.
good work. thanks. :)Quote:

The B cpus all clock well and i so far have only seen them get better with newer weeks. But the way you state it makes it seem like a 31B somehow isnt that good compared to a 29B.
Like i said above it would probably be best to leave the portion out.
you come to a forum to get help and YOU chastise me for trying to help!...you ungrateful fool!:mad:

Thanks for the info.
Regarding NCQ for SATA, this is where u enable it
http://img166.imageshack.us/img166/2323/ncqar6oa7.jpg
Several users have reported that there is a bug with NCQ in Windows
XP, ranging from small freezeups to not being able to boot problems
So if u experiance these kind of problems u will have to disable it again.
Also read review of NCQ on Tom's Hardware : Can Command Queuing Turbo Charge SATA?
Esspecially on page six of this review where u can see comparison charts nonNCQ vs. NCQ enabled drives
Also I found a good hd bench software : Nodesoft DiskBench
The program is using the current filesystem to save a file. If it is fragmented, the performance will be degraded, as it is in real life.
So, to figure out how fast your computer is, you can copy a file from A to B and use a stop watch.
Or you could just as easy use this program.
All it does is:
1) copies a file from A to B, times the time it took, and deletes the file from B again.
- or -
2) The other way to benchmark is to choose Create File. This way it just creates a file (consisting of a repeated 128 byte string). So if you only have one harddisk, this is the optimal test for you.
Questions :
1. Have someone actually tried to use 2x4 connectors for CPU power supply, and what are the advantages or disadvatages of using/not using it?
2. Few users have reported voltage spikes that destroyed their memory, so have anyone experienced voltages spikes while working normally or running orthos, on unmodded boards?
3. Where can drivers for Wifi be downloaded, since there is no link on official webpage?
4. I noticed that some users posted links to asus ftp server. How are u able to get listing of asus ftp server, since i get denied directory listing error?
Dude, there is no C for any week, only A and B, and I've only seen an F.
NCQ is not activated like that, at least not on Intel based boards, that's an nforce you posted there, it's not even similar.
And to answer your questions :
1. Yes, I have. Didn't notice any difference.
2. No.
3. No idea, sorry.
4. It's easy actually, copy a download link from their FTP and delete the file name. Worked for me.
Thanks. This option isn't viable to me cause i have other fan connected on chassis headers and want to run them 100%. Thanks anyway!Quote:

Some advice needed.
I got a 6600, have had it run at 3.2ghz since that have been the sweetspot for it.
I got some issues now that i dont know what is the cause of it.
I cant get it to boot other than at 9x319 or lower fsb.
I tried anything I know of to get a higher boot but to no avail.
My specs are,
p5b deluxe wifi.
2gb corsair 5.5.5.12 and I use auto in bios for a 5.6.6.18
6600 core2duo
raptor hd.
Hiper 580w replaced by a Cooltek 600w psu.
x1950xtx
watercooled.
vcore 1.55/1.6 tried different variations.
I flashed to bios 9.10 and it run fine also. tried to overklock a little with the new psu to see if could go a little higher.
Reflahsed back to 08.04.
No go.
The funny thing is, I cant boot it at 7x400 or 401 or similiar.
8x401 and such is a no go also.
Trying to find out what is the cause of this either it is the mobo who are acting up or it is the cpu.
My guess is with the mobo.
I tried to set manual memory timings which does not work at all. (never has with the mobo)
Auto seems to be the only one it boots with no matter what i try.
So, since i cant get a stable boot on any combinations at a higher fsb which I have had a long time before it seems for me to indicate the mobo.
I have had it boot at 8x400/401 but very rarely and it seems most luck and when I mananged to get such a boot, then restarting does not boot up.
so, what to do?
Tried clockgen and got a 3200mhz without any lock ups.
What are your vFSB, vMCH voltages? You should raise them a bit when overclocking.
I always used auto which have worked very well.Quote:

using vmem at 2.05 have worked well also.
Using clockgen I get it up to 3.2ghz without an issue.
Anoyther thing that just happen, when saving into bios it does not reboot but left the biosscreen open.
had to manually reboot from bios.
Maybe it helps:
In Bios CPU Function I have everything disabled but CPU TM, Execute Disable Bit and PECI. The last I think it's for getting more accurate temps.
On the other hand, anyone knows why I can't use CG to raise my FSB? Should I use small steps increase? Because otherwise I get blue screens.
I'm booting in 1066 strap, FSB 400, and I'm trying not to jump in 1333 strap. I read that over 400 you're in 1333 strap. What am I missing? :confused:
Ups, sorry... i thought it was the same, and since I didnt yet assemble my rig, i used a pic from belgian system admin with nforce chipset.Quote:

No, you can't disable or enable it, just from BIOS.
I was benching my pc last nite to see if everything was working ok. My new case hasn't arrived yet so I thought it would be a good time to check everything else out. Unfortunately I can't get it to boot up. I double checked my connections. I have both 2x4 connectors installed. And I even tried it with just one. I reset the CMOS. It just doesn't want to post.
The LED does lite up and the fan on my vid card jiggles a little bit. I'm thinking that I might have to try a stick of 1.8v ram to reset the voltage in the bios to get my pc running. Does that sound right to all of you?
So a few days ago I go to my pc only to find out that it had apparently rebooted and stuck
on the windows loading screen. Upon rebooting I get no post, no error beeps, no nothing...
Somehow I just figured it was the North Bridge or a mboard related issue (I have an inverted
motherboard/case and they have issues with heatpipes on most boards). I figured the
Norhbridge probably burned out or stopped. Even power cycling to clear the settings didn't
work... I even took out the battery and cleared the cmos data that way... No Avail. So I
figured it's definately the board. ANYHOW I got a new p5b-deluxe yesterday and replaced the
nbridge cooling with a thermalright HR-05 and the other chips with some ramsinks... my first
boot was just fine, just changed the date in bios and booted to windows. When I got into
windows since it was the same board windows acted like nothing changed. So I proceeded to
update my bios to the 0908 revision like I was using on my previous board. I reboot and now
back in the same boat... the new board won't POST and I haven't even touched the voltage
settings or anything. When I try to boot it does the whole double boot thing that usually
does when you change voltages etc... where it will start up for about a second..power back
down then fully start again. Now heres my dilemma... I could have possibly put my nbridge
cooler on wrong... and the nbridge burned out again possibly (even though I never touched
the stock settings)... Or maybe there is an issue with those particular bios (which doesn't
make sense because I was running that revision for like 3 weeks on the original board before
there were issues.)? Or maybe with this bios revision there is a hardware compatibility
issue? I'm stuck... I need my pc up and running and willing to buy a THIRD board, but I
can't keep going through this. So now I'm thinking which board to buy... ANOTHER p5b-deluxe,
an asus Striker, the new RD600 DFI board... Not sure what to make of this issue and also
what to buy next or how to fix the old board.... What do you guys think? I know there is
alot of information here and alot of questions... any troubleshooting tips or advice about
this board or the possible purchase of a new one would be GREATLY appreciate.
I need a stable board that I can get as close to 500FSB with 1:1 and good timings as
possible... I'm a gamer and this machine is my powerhouse machine so I need a board that's
made for performance, features, and to be pushed with the newest games...
Also, someone suggested trying different ram just to get the board setup...
Whats a good cheap 1.8/1.9 volt rated ram stick I could buy?
I ordered a $32 stick of patriot 1.8v DDR2 off Newegg this morning. But with shipping and express service it comes out close to $50. $50 for a stick of ram that has no purpose other than helping me my mobo to boot up. What an incredible waste of money but I have no alternatives that I can think of.
So you really think that the issue is probably a RAM voltage issue, and that I didn't even need to order this other board? Is this a common problem with this board or with 965 chipsets all together or what?
Kumakichi
Hi. You can reprogram the SPD
I believe that it could possibly be the ram voltage issue. I've read about this happening with 975 and 965 chipset boards. On forums like this one where people are avid overclockers a lot of these guys have extra parts sitting around so a ram swap for bootup is a minor thing. I think thats why you don't see much mention about "hey I had to swap in 1.8v ram to get my mobo to post" type of replies. I've been overclocking for around 15 yrs now but I'm not addicted to buying hardware. So my extra parts boxes dont have much in them and I certainly don't have DDR2 sticks sitting around.
Some bios' are fussier than others as well. From what I read 0711 is pretty good in that respect. I haven't read as much about 0806 or beta. Supposedly in 07xx and on versions one of the fixes addressed better support for ram. Perhaps that didn't mean from a voltage sense. I have read some posts where people concluded that by flashing to a newer bios it set there voltage back to default which could cause a problem if your ram won't post at 1.8v
I think you have 2 alternatives. Buy some 1.8v ram locally from a store that has a good return policy. This way you have a choice whether to keep the ram or not. Or mail order it from some place like Newegg. If it works its probably not a bad idea to keep the ram and use it as a boot up tool of sorts. Somewhere down the road it could come in handy.
How can that be done ? Reprogramming the SPD I mean ?
We could do this to our ram? I recall reading something about this but I forget what it was about.Quote:

Anyway I have regular Corsair 6400C5, and didn't have a problem. But that only needs 1.85-1.9v That one of the reasons I bought it (the others were price and the fact that I wasn't getting cooling that would let me go past 450FSB anyway)- even in August there were plenty of these types of stories and it seemed to be the accepted wisdom that the BIOS was not recognizing the required RAM voltage and thus booting with high-end sticks was nearly impossible.
I haven't heard a similar prob for a long time on a P5B also...Quote:

Where can I find that list of compatible RAM at for this board?
I'd be willing to bet that our mobo's have pre-07xx bios.Quote:

QVL RAM is on the left side of the product page...Actually since it only goes up to DDR2 6400 RAM there isn't anything on there that needs more than 1.8v I think. It hasn't been updated either since I looked at it last August.

well it happens to me 3 times already....unplug de 24 pins and the 8 pins from the cpu,took off the batterie,one dimm on the yellow slot further from the cpu,and clear cmos all night long.Quote:

Thanks for all your help guys.
In bios under the hard drive options where it says how to run the sata drives... the options are RAID, IDE and ICH8.... what does ICH8 do? Anyone know?
ICH8 is AHCI mode, update your BIOS, since 0711 it doesn't say ICH8 anymore, it says AHCI as it should.
i have overclocked my e6400 to 3.2 Ghz but at post it reports my clock speed to be 16.92GHz !!!!!!!
wtf
windows & cpuz reports the correct speed
anyone else have this ???
So what is AHCI mode?
that's normal, don't worry about it. it's just stupid incorrect readouts.Quote:

is this XtremelyLazy.org/forums ? ;)
Yeah thats why we build computers that can think for us :DQuote:

If u do mutitasking - yes, if u do normal operation - slighty or none.
That is offcourse in theory, u cant know until u make the comparison realtime.
Maybe somemone that has been using IDE and reinstalled to ACHI, can share some info?
So anyway, yesterday I finally got my gpu and mem, so i assembled it, and booted. I was happy as a child, since i was w/o cmp for almost 3 months. :woot:
It booted fine, i got into BIOS and set it up and when i pressed save, I almost got a heart attack - computer shutdown like I cut power to it... I could hear my HD head fell as a rock. :slobber: :slobber: And then it turned on again by itself fine.
I have read all there is about this board, but until u acctually experiance this, u have no idea how it really feels, esspecially if u have data on disc, or after u did OC.
And then during post i saw that my revision is 0507. Jesus, its even miracle i booted fine.
I can tell u, ASUS makes good boards, but always manages to kill all that hard work and beauty with some little crappy thing that annoys hell out of ppl. :slapass:
After that I had a mishapp with partition magic, so i spent all night repairing partitions... and then i realized that i forgot my AIO in the firm, so i went to sleep, and will be finally doing the system in about an hour or so.
Piece of advice which most of u probably allready know : Never do anything with computer when u are tired. U will live longer :D
Next time i write here it will be from my own comp :banana: :banana: :woot: :banana: :toast:
if your drives do not support NCQ then i assume there is no benefit to using ACHI mode?
Can't get my CPU lower than 50C idle for some reason... I bought a new board because some other issues and added EXTRA AS5 this time on the chip but no matter what I do, it still stays between 47 to 50C at idle... what could I be doing wrong? Maybe I'm mounting it wrong or something else? There is an issue with the square piece of foam around the backplate of my cooler (Tuniq Tower)
Since it had adhesive on it and stuck to my original board....but I don't really think that piece is THAT important...I got the backplate on just fine and screwed the HSF in as tight as I could without cutting my fingers too much LOL... why in the heck do they make that heatsink so freaking sharp...? LOL
ANYHOW this has actually made me want to try other types of cooling other than air...but I'd rather stick with what I bought than spending more cash...
Suggestions?
OH YEAH this HSF is REALLY hard to get on so in installing it, it does slide around a bit...could that have slid some AS5 onto the side of the IHS possibly or something or what? Any help would be appreciated.
More AS5 can actually increase temps, maybe you should try lapping the base of the cooler and properly installing it again.
Hey guys, which bios are you using on P5B DLX, is there any modded bios which works good on that mobo?
regards
Gosh, I was using only 1gb stick ... So I decided to buy another 1gb today for dual-channel ... cpu-z show as dual channel, so does the bios at boot.
I tough about getting a higher score at PcMark05 , but no increase whatsoever for dual-channel ? WTF ?
I've made some testing with 0804 and 0910 regarding PECI option in CPU Functions.
On 0804 with PECI disabled TAT reports bad temps, one core with negative temps, and the other with positive. -43/~50.
If I enable PECI everything comes back to normal. ~48-50 in idle with TAT and ~35-38 with Asus Probe. On load with Probe goes up to 50.
On 910 with PECI enabled or disabled I get same temps with TAT(idle 50/load 65).
But with ASUS Probe, with PECI disabled the temp remains constantly at 40(idle or load).
After enabling PECI the temp with ASUS Probe is higher than the one reported with 0804 bios, being around 40. Also higher on load, 55C.
Pretty strange, I might say. Hope I haven't done anything wrong or get confused with all those temps.
My C2D is at 3.1Ghz, 1.32 idle, 1.304 load, 1.350 bios.
So what does PECI do afterall ?
LittleDevil Everyone use the last one (0910 current). There is no any modded bios, cause it inpossible to do it.
Hey, maybe disabling or enabling PECI can hlp with sub zero temps? Cause I remember when it was auto - TAT always reports that CPU temp is +13, but in real it was -17.9(S&M says that) Anyone can try?
