ASUS P5B-Deluxe; Problems & Fixes

[mele]

OK I GIVE UP!!!!

This motherboard is a piece of !

Going sell it on Ebay and try something less ing flakey!

[ziddey]

oooh

[Angelico_Payne]

Well sell it to me then.. so i can make another computer... it is true that this motherboard is acquired taste, and not for feable, but it can work, and is worth every penny, pound, drahma, beaver fur, or what ever u are using as currency

Lian-Li PC60B+2

Asus P5B-Deluxe, Rev 1.03G Bios: 910
C2D 6400, L632A919, Arctic Freezer Pro 7 HSF
Team Xtreem PC2-6400 2GB DDR-800 4-4-4-10 2.0-2.2V Dual Channel
Sapphire Radeon X1950XT 256MB
OCZ 700W GXS PSU

I am a newbie, I'll admit it, and I can't find any coherent info searching on the net so please help me...I am reading the long 150 page p5b deluxe thread on here, but it just stresses me out....

I need to understand what some of the bios options are? and what they do? reading the manual is useless.

I have no idea what those many DRAM settings are in the bios, I just know what the first 4 do, and I matched them up with my RAM timings.

I am trying to use CPU-Z v1.39, and it reads my CPU at 1.6GHZ, then I used the AI Suite and it reads them more accurately. Which program should I use?

I also noticed that my CPU jumps up and down depending on the load it needs.... I believe there is a setting to disable this so it always runs at stock high. Is it " Inter SpeedStep" or is it "Speed Spectrum" I disabled both and the cpu-z still reads at 1.6ghz. 266fsb, is there something wrong with this version of cpu-z?

I must also note that I have not done any windows updates yet, I installed Windows XP Home SP2, waiting to do updates until I understand all this.

So someone please who has the same rig as me, send me some screenshots of the bios settings, and please explain to me how I can run the system at stock and not have it jump all over the place.

My Ram Ration in cpu-z reads 2:3, I want to change this to 1:1 I believe

Thanks

Jmicron question,

If I disable jmicron in the bios, my optical drives do not show up once my system boots, if I enable it, they show fine. Does this mean I should install the new jmicron driver? I don't plan on using RAID....

I heard also that the only way to get rid of the annoying "optical drive" message upon boot, "press any key to continue" is to disable the jmicron setting in the bios...

What to do?

[sluzbenik]

Pepi - yeah it's Intel SpeedStep. When voltage is set to auto it will reduce the voltage AND lower the multiplier when the processor has no load to save electricity. It's fine, you can leave it enabled, it's supposed to do that. When voltage is not on auto, it doesn't really save you any electricity since constant voltage is always being applied but the multiplier still changes.

Not sure what CPUz and AISuite would give different values. Probably because of SpeedStep. AISuite does refresh faster...

If you want IDE support, you must use the Jmicron. Don't install the Jmicron drivers. You have to live with the pause, it only lasts like 2 seconds...

Read the guide to Intel overclocking in this forum to get started...And the p5b bios setting thread.

Easy 3.2 overclock with the 904 bios -

set RAM To 1:1 ratio (first option in RAM speed settings), change voltage to 1.375 (maybe high but with this BIOS I need that extra .5) and set FSB to 401. Change all chipset (ICh7r, etc) voltages to the first setting (don't leave them on auto), which is the default, and lowest setting. You shouldn't need to change the RAM voltage for that OC.

...by using some proper thermal goop instead of the intel stuff that has been on there forever...

Good idea. Arctic Silver's website will have pretty good instructions for what to do. A little bit is better than a lot.

OK I GIVE UP!!!!

Lol, I feel the same way. I've never had good times w/ Asus boards tho. A7N8X, P5P800, and now this one. There really isn't a better board out for my needs at this time tho. Too bad DFI couldn't hurry up w/ their 965P offering.

[xgman]

I think alot of these P5B problems can be attributed to RAM compatability.
IF you have high end micron RAM (TeamX or G.Skill etc) you might need more volts than the defualt 1.8 the board supplies..
If P5B #3 has the same problems, I'm considering VDIMM mod to bring the default to 2.0V or 2.2V

Isn't it sort of rediculous that we would have to resort to this just to boot our expensive ram?

Google finds nothing, what does this mean?

[OMEGA3]

Was not this Vfsb mod shown already...?

The FSB limit seems not to change though Vfsb mod was tried.
It changes in each CPU's.

Sub timing question?

does someone know of a good combination of sub timings to increase performance on the p5b deluxe??

my rams are already at 1200mhz 5-5-5-15 but my ram sub timings are stock , so if anyone know of a successful combination plz tell me

and what is better 400 fsb or 401 for games?

Damn, I thought there was only rev 1.03?? I wonder if Asus fixed the 16x PCIE issue on this rev

400fsb. get mbench and do quick runs with changes in memset to see what's best.

I'm using 3-9-4-10 at the moment. I've found that when I run my ram at slower speeds and using spd, it'll set 3-9-4-11, so I worked from there.

Also, trfc has a bigger influence than the others I'd believe. Since you have d9's, try for 35, 30, 25, 20. You'd probably find it stable at 25 though since you're running 1200.

That said, running a 2:3 wouldn't help that much in day to day things. If you could run 480fsb and 7x multiplier and 4:5 for ram, your cpu would be 3.36, and ram at 1200 again, but you'd make a little better use of it.

but i don't think my motherboard can handle 480 fsb :\

Yea the weekend! But I'm starting to feel very uncomfortable right now...



Click for 3MB hi-res pic of Asus P5B Deluxe that got on the wrong silk screen lane...

hey anybody else here running with 4GB? I can only see 3.5GB in 64-bit XP or Vista with memory remap enabled(only 3.2GB with it disabled).

can this mobo work correctly with the full 4GB showing in windows?

just noticed in fact even BIOS is only seeing 3.5GB yet CPU-Z correctly shows the 4GB. is this a known issue with p5b?

[Mr Dead]

running 4gb here on vista ultimate x64 with no probs. 4gb all there and useable.

must be with these OCZs then, I take one out and 3GB shows in BIOS. put it back in and 3.5GB again. tried swapping them round, the sticks are 100% working just will not show in BIOS or windows as 4GB though fine in CPU-Z. bah!

well ive got an evga 680i coming tomorrow so im sure they will go fine in that. lots of benching to be done.

I have problems with Wake On LAN. In BIOS I've enabled Power On PCI and Power On PCIe, both interfaces are enabled with Boot ROM. In WinXP I've set in HW properties Wake Up Capabilities to Magic Pattern and Wake On Shutdown to On. I've checked that the computer receives magic packet (using Wireshark) but it will not wake it up.
Strange thing is that when I shutdown the computer, LEDs on switch for one interface goes both off and for the second one the 100MBps goes off but Link/Act is blinking.

Any idea what to do, or test?
Thanks.

Hi,
I can not change the Command Rate ( CR ) in bios, it is now on 2T.
Do you have the same thing?Can you modify it??

[tzitzos]

command rate is always 2T at the p5b
you cannot change it

I don't mean to spam or anything, but this is simply too huge of news and I figured I'd try to spread the word as fast as possible. I noticed something interesting yesterday. When I had misc. voltages bumped up beyond stock (vmch at 1.6v for example), I noticed that even without a fan connected to the cpu header, I'd get an rpm reading of 42. I figured this must have meant there's a lot of electrical noise in the motherboard. Also, I noticed I wasn't able to pass beyond 460fsb stably, and at 460fsb, I could use all stock voltages.

So that got me to thinking about what spread spectrum did. I've always been told to turn it off and always have. But after thinking about it, I decided to turn it on and try fsb500 with all voltages at stock. Holy mother ing . It posted. I reset it several times (at 460fsb, it'd randomly not post when I had spread spectrum disabled) and it came one each and every time. I'm running memtest #5 and it's passed 4 iterations already. This is simply unbelievable.

My p5b (vanilla mind you) which has never seen beyond 460fsb despite misc. voltage bumps is now sailing at 500fsb with stock voltages across the board.

[allany]

Very impressive

[pumbertot]

sounds.....unbelievable? I will try it out when I have my tuniq, im just running crappy cellie just now so cant set FSB high.

yeah i was totally blown away. I can't believe I added two and two together and it worked so well. I guess the long lasting spread spectrum idea got shattered.

I did a test again with spread spectrum disabled and on save and exit, it no longer posted and I had to kill power to the psu.
