MY BIOS settings for P5B Deluxe

[Regalk]

For guys with rock solid overclocks - I thought if we have a thread with BIOS settings we can put our heads together and come up with optimal settings plus it will be helpful to newbies joining and not sure what to change in BIOS

Here are my BIOS settings - CPU temps using an E6300 with Thermaltake Big Typhoon around 46C idle and 60C load with chipset temps around 36C constant and SB 40C. RAM is Corsair XMS2 DDR2-800 rated at 5 5 5 12.
TIP - copy and paste these in your reply and change

Surprised that no one else cares about contributing - anyway hope that it benefited some - it took me almost 3 weeks to get to 3400 and with all sorts of home grown solutions out there you have to sift through a lot of stuff. Still don't really know how some of the RAM timings work other than just monkeying around with them.

 

[Boa99]

Great Info! Thanks for Posting.

I have a P5W and a little trouble with stability over 320 FSB.
(Corsair DDR2-800 MHz, P5W, x1950xtx) (Voltage and Latency already changed 20 times)
(Temp is about 45C° running Prime95, prime is stable but battlefield 2142 not it crashes after apr. 2 Minutes)

If you have some more tipps, keep it coming.

 

[Regalk]

Noticed something else I have since decreased the Vcore to 1.425 and temps are 44/42C. The system feels more spiffier now - programs load a lot faster - only change I made. Looks like these bad boys like cooler temps BUT not 100% stable - good for everything except 3D games which may crash after a while (3Dmark 2001 runs as well as 2003 and 2006) UT 2004 so so

 

[n7]

I can run either 8x425 4:5 or 7x486 1:1
For 7x486, RAM is DDR2-972 4-4-4-4


Bios 0711

AI Tuning = Manual
CPU Frequency = 425
DRAM Frequency = 1063
PCI-e Frequency = 100
PCI = 33.33
Spread Spectrum = Disabled
Memory Voltage = 2.1-2.3V (haven't nailed it down quite yet - using 2.3V for most of my testing thus far)
CPU VCore Voltage = 1.45V (in Windows, this results in 1.42V idle; 1.4V load)
FSB Termination Voltage = 1.3V
NB Vcore = 1.45V
SB VCore = 1.5V
ICH Chipset Voltage 1.057V or auto

Memory Remap Feature = Disabled
Configure DRAM Timings by SPD = Disabled
DRAM CAS# Latency (TCL/CAS) = 5
DRAM RAS# to CAS# Delay (TRCD) = 5
DRAM RAS# Precharge (TRP) = 5
DRAM RAS# Activate to Precharge (TRAS) = 5 (warning: most RAM cannot run this low)
DRAM Write Recovery Time = 6 (this i will tweak more later, but i can go down to 4)
DRAM TRFC = 42 (improves PI times, but i haven't tweaked it for 24/7 yet; likely will be using 30, since 25 isn't stable)
DRAM TRRD = 10
Rank Write to Read Delay = 10
Read to Precharge Delay = 10
Write to Precharge Delay = 10
Static Read Control = Disable

Aside from TRFC, in the testing/benching i have done, the last five setting affect performance in a very minimal way, so i haven't bothered with them much.


I am lucky i guess, as i haven't experienced the PCI-e 1x issue or any other real issues actually.

 

[tommo123]

thanks for this

am not putting a conroe in mine, i just built the basic today with a PD 805 i had laying around - until i get a quad core anyway.

hopefully some of the above info will come in handy

 

[Regalk]

N7 -- you said can run either 8x425 4:5 or 7x486 1:1 - can you explain how you get memory to run at 4:5 I could not find any settings to change the memory to run async unless I overlooked something - Oh yes i see now you can go faster than 1:1 but not slower than 1:1 - ignore my comment above

Yeah, 5:4 would be running the FSB faster than RAM.
4:5 is vice versa

 

[Raider1284]

well if you run the memory using SPD wont it run slower then 1:1 if you raise the FSB?

Originally posted by: Raider1284

No. Timings might be looser, but as mentioned, there is nothing lower than 1:1 for pretty much all P965 mobos

 

[Malk]

I would like to see which settings you would use for 350-400 FSB as i cant go much higher due to air cooling limitations.

So if any of you would try to help me with this i would greatly appreciate it

 

[n7]

370-399 isn't likely going to work terribly well.

I'd suggest dropping to the 8x multi if you have trouble with that range on the 9x.

Here are my Bios settings, I have two different configurations, one for 3,2Ghz and another one for 3.6 Ghz, I'll post both of them so that people can appreciate the changes made, specially concerning RAM "misterious" timings for many..hehe!! Remember both of my configs are ORTHOS Blend test +12 hours stable. Ok, here we go:

i received the zalman and placed a fan on the northbridge and put arctic silver underneath north and south bridge and can run at 480 fsb. i had to bump voltage up so i run it at 477 now.

 

[Regalk]

Doing that is also good - but not really necessary. Mine is at 486 FSB and I play games for hours on end
My XFX7800GS is really at its limit at 607/824 but runs good even after 3 hours game play - so even with MB, CPU and video card overclocked no crashes
The only problem I have is at start up every day The windows XP scrolling screen stops and I have to reset - after that all is good.
One additional minor issue I have is when viewing pictures/photos the monitor suddenly blanks for a second and comes back on - happens when using Firefox and viewing photos

 

[ingenue007]

UGH i have issues loading. i think it is the newest bios. i didn't have issues before 804. i can't do a restart and have problems shutting down and starting. none of this occurred with the previous bios i was using.

[ingenue007]

i put some copper HS where there is supposed to be another HS near the CPU and can run at 480 w/o orthos errors now at lower voltage than previous.

last bump

Hi This is my first time to this site.
I cant seem to get my system beyond 2.99. It wont boot passed that mark.
Any suggestion as to why it cant go higher or is it my ram topping out?


P5b Delux-WIFI rev 1.03g Conroe E6300 @ 2.975 with 711 Bios 7x425
Memory OCZ 6400 Platinum @ 2.2 4 5 4 12 Timing

[Roguestar]

Loosen the ram timings just to be sure, then try it again.

 

[josh609]

I have an Asus P5b Deluxe and I can't seem to get my FSB over 322 without it staying stable. I have Corsair XMS2 DDR2 675Mem and the ratio at 1:1. My CPU voltage a 1.37. I have an E6600. What could be my problem?

Set your memory to DDR2-533 (the lowest setting). Your memory speed goes up with FSB and will really be operating at 533*322/266 = 644. Your memory should be OK (less than 675), if still unstable increase its timings.
