ASUS P5B-Deluxe; Problems & Fixes

[chuckbam]

hmm, found this thread too. i dont want to repeat the post so go here to read it: http://www.xtremesystems.org/forums/...&postcount=701

also chuckbam. i seem to have the same mobo/ram/cpu as you. id love to get your exact bios settings if you could message that to me. ram timings etc, etc.
thanks a bunch.

Hi,
My settings are basically:

CPU.. 360
DRAM 900
PCI Express 100 ( Any higher it keeps reverting to 1X bus vs 16x on some re-boots)
PCI Clock 33.33
Spread Spectrum .. Disabled
Memory Volts 2.3
V Core 1.3875

CAS 4
CAS Delay 5
RAS % 5
RAS Active 12

Ie 4-5-5-12

For some reason, default or looser memory timings result in a overclock.
failure. I was running 4-4-4-12 when I had 2GB RAM. But when I went up to 4GB, I had to change it to 4-5-5-12. I tried about every RAM timing possible on this board.

Most everything else is at default.

I had greater overclocks but I settled on this for stability and 24/7 operation.

heh, when my pcie freq is 100 it runs at 1x, i changed it to 110 and it enables 16x.. odd how its opposite.

ok ive copied those timings off you, ill try tightening them up after i find out if this is stable or not (so far so good). but i was wondering about the other timings. TRFC, TRRD, etc. could you post those as well please?
thanks.

I do not have enough knowledge to adjust those. There are no specifications for the memory available and ASUS provides no information either. I keep them at default. I do know that my memory is T2.

If you find any improvement for adjusting any of the other settings, please let me know.

The PCIE thing is odd.

Is there anyone here that could give me concrete BIOS-settings so that I could get my E6600 to 3GHZ? I've tried reading some overclocking-guides but most don't make any sense to me.

I'm using http://corsair.com/corsair/products/...X2048-6400.pdf if that's any help.

The memory specifications are only the 4 basic settings and voltage.

I've hit a wall with my P5-B - any ideas please ?

specs are E6600 (L624), original ver of P5-B Delux, 11.01 bios, 2 gig 8500 Crucial

9*365 with Vcore @ 1.5 (set in bios), memory at 1090 CAS5, Orthos stable (Blend) for 10 hours

9x370 with Vcore @ 1.52, memory now dropped to 960 so 4:5 multiplier (I've tried both CAS4 and CAS5 to no avail) - Orthos Small stable for over an hour - Orthos blend always fails at about 35 mins, whether RAM set to CAS4 or CAS5.#

normally if I have Vcore set too low for the CPU, Orthos small fails much quicker than Orthos blend, so I'm suspecting RAM or Mobo. RAM I've had up to 1030 CAS4 - so I doubt that.

Mobo voltage settings are ICH to Auto, all the rest in the "pink", can't remember exacts but MCH is 1.45, South = 1.6 etc.

I can't try the x8 or x7 multiplier as my mobo/cpu combination HATES it with a passion - 3.25 gig on x9 only needs 1.5Vcore, but 3.2 gig on x8 needs 1.525 just too boot !

thanks for any tips, Mark.
