P5B Deluxe: BIOS screens for maximum overclocking success

[z3speed4me]

did anyone ever put up p5w dh bios screens for "optimal" oc, maybe i missed them...

[kenofstephen]

want FCG back ........ :'(

Thanx for some of the earlier posts that helped me with my 'close cousin' mobo... did this back in February but last month rebuilt it into a new desktop. Runs BOINC 24/7/365 in addition to desktop duties so CPU is always at 100%.

E6400, Conroe/Allendale, Rev. 6-F-6 6-F-B2
CPU @ 3.20GHz (3200.05MHz) - 8 x 400.01, bus 1600.03, w/ vcore set to 1.3875v in BIOS, reads 1.320~1.328v. CPUZ under 100% load 1.304~1.312v.
vFSB=1.200v, NB=1.40v, SB=1.5v, ICH=1.057v

Any new beta bios folks ?

Are any of you guys with 2:3 in the mem ? Any problems ?

Some times when Saving & Exiting the bios, using 2:3, it freezes and doesn't restart ! But the changes ara all saved.

Any idea of what it is ? Could it be because of the 2:3 memory divisor ?

My 24h/day system is like this :

Can someone explain the result of the FSB strap change at 401 on these boards?

What happens to what timing signals (RAM frequency) that is different at an FSB of 400 vs 401? If possible could you use my FSB of 400 running my memory at 1:1 (DDR2-800, 400MHz to memory) and tell me what happens to what numbers if I bumped to 401 (I think that's the 'strap change')?

Thanx in advance, Skip

It would take along time to explain the 'Theory.' Each seccessive strap is slower than the previous one. Check out the following link;that will explain it better than I can.

Thanx, read it... good write up. Everything else I've read on P5B-Deluxe and P5B-E says the strap change appears to be at FSB=401 instead of 400. Maybe a newer BIOS.

I got a good, fairly short, explanation of FSB strap HERE.

Guys, please help me out, which is the better bios i need to use for my QX6850 using my Asus P5B De Luxe mobo? this is not the Wi-Fi Edition, i have read in one thread that you need a bios 1215 for you to run the qx6850... I am contemplating between the 1215 bios and the Latest one, which bios would you prefer i you are going to update your bios if you have qx6850? Thanks...

[Buckster]

my P5B with my Q6600 @ anything over 4x425 - seems to need 1.45Vfsb

is this ok long term ?

thanks, Mark.

Can someone upload the BIOS screens? They are not on the first page of the thread.

Why is cpuz 1.42 reporting different cpu temps than 1.38?

I'm getting some different readings from 1.38 to 1.42. Specifically the cpu voltage readings with Speedstep enabled.

My Core Duo 6600 is overclocked to 3.2 gigs.

With cpuz 1.38 at idle, the cpu voltage is 1.050 volts and cpu speed is 2136 mhz. When running an intensive program, the cpu volts jumps up to 1.28 volts and cpu speed jumps to the 3.2 gigs.

With cpuz 1.42 at idle, the cpu voltage is 1.29 volts and the cpu speed is 2136 mhz. When running the same intensive program, the cpu volts actually goes down to 1.28 volts and the cpu speed jumps to 3.2 gigs.

Something is clearly not right. I would say cpuz 1.38 is right and cpuz 1.42 is wrong.


I really need to know what's accurate here.

I would think that cpuz 1.38 is correct when it is showing a lower cpu voltage at idle for the lower cpu mhz reading. That makes sense.

I would not think cpuz 1.42 is correct showing actually a higher cpu voltage reading at the lower cpu frequency at idle than when the cpu goes to full speed.

Thx, great work

Hello,

I'm going to get a e6850 to replace my e6600.

I intend to not overclock it too much as I'm trying to get a near silent machine so I want to overclock the e6850 just a little, e.g. maybe to 3.2/3.3 GHZ to avoid having to make my fans too loud.

Woud you have any recommendations in terms of the correct settings to get such a minor overclock on an e6850 using the Asus P5b?

Thanks

I need it too.

[MrRevhead]

Also would like a link/mirror to the original images that were on Post 1.

I have misplaced the print out I use to have. I cannot PM FCG as I think he has PM's disabled.

Several months too late, but hopefully it'll help anyone still looking for these.


Edit: Hmm, the image tags didn't work for me, so here are the links...

[cmanser]

Can anyone shed any light on a video card problem I am having.

just put a 4870 x2 in my P5B Deluxe board and the system seems to be running slower playing games than my 8800 GTS 320MB card. Are there any BIOS setting I need to set for the card to run properly? This is BUGGING me because it should be screaming with the 2 4870 chips and 2GB of video memory.

HELP!


Thanks

Check to see if your PCI-E slot is running at 16x as sometimes under certain conditions it can revert to PCI-E x1

yup! you can find out using cpuz.

Folks...

My rig specs are below. This comp is plenty fast enough for us. My son and I are gamers, and play online COD-WaW. This comp is the 'gaming' machine in the house.

However, I think I got carried away a year ago and bought memory that's too fast for this MB. (G Skill 'F2-8800CL5D' DDR2-1100/PC2-8800 5-5-5-15) I have had to slow it down to get it to run. Also, will not run 8 gig. (I did change AHCI in bios).

One local tech said this Asus P5B-d will not run 8 gig of ram if the cpu is OC'd, regardless of whether one has the latest 1238 bios or not....so, either OC the cpu, or run 8 gig ram.

Having 8 gig versus 4 gig ram is not going to improve gaming performance, correct? If this is true, then i don't care about running 8 gig of memory.

I think the latest 1238 bios helps getting the MB to run 8 gig of certain types of ram, and does nothing to help overclocking the cpu.If this is true, then there is no reason for me to flash to that 1238 bios. The rig is stable and fast now.

What I would like to do, is have a more aggressive OC of the cpu, to get it to 4.0ghz. Many peeps who have this MB and cpu have had little trouble getting it to 4.0 on good air cooling. I have an excellent HSF, the Xigmatek s1283.

What do you folks think?

[ryant]

All i have to say is that this board still rocking on my rig with a 3.7ghz quad core and 8g of ram

[RIRed48]

ryant...

Questions, please...

Which bios are you running?
Could you possibly post all your Bios settings in detail for me?
I would rather run my cpu at @ 4.0ghz than have 8 gig of ram....if I can't do both...

Thx for any help...
