"ASUS P5Q Deluxe discussion".

[CryptiK]

Am i right, does -E and Deluxe have same NB cooling ? Atleast it looks like perfectly same

From pics it looks to be the same, except the P5Q-E has no heatpipe from NB to SB, and I've read that it has no backplates on the Mosfet sinks as it has 8 phase PWM and no fets on the backside of the board.

475 FSB, 333 strap, 5:6, 8GB RAM at DDR2-1140, tRD 8 / vMCH 1.40, vDimm 2.0v


448 FSB, 266 strap, 4:5, 8GB RAM at DDR2-1120, tRD 7 / vMCH 1.44, vDimm 2.0v


from past experience with this board, in order for me to set tRD 7 when system overcloked above 400fsb, this used to be possible only to use 400 strap (e.g. 400fsb / DDR1066, 450fsb / DDR1200).
also, my gskill 8GB kits (2 kits of 2x2GB) have never overclocked well on this board, the ram kits are not a very good overclocking ram by themself, however, the ram kits can now be overclocked to DDR2-1140 (and not on a low fsb), this used to be max stable at around DDR2-1128 for 8GB.

That's really nice to see that FSB with a quad and 8GB of ram at that speed stable. What is Ai Clock Twister set to and are you running static read control and dram read training enabled? They gave me a nice boost in performance, as did running clock twister on stronger. Not sure if you could manage that with a quad + 8GB at those speeds though.

I'm just happy to be stable; the system is far more powerful than my needs anyway. Fast, quiet and able to game with insane FPS when needed. I enjoyed the learning process but I'd be quite happy never to sit doing prime95 runs again Can see this system lasting a few years for me.

Good to see a wholly satisfied person, your setup is nice.

opp sorry i haven't answered any of the questions...

static read control - enabled (in some of the previous bios versions i set this option on auto. but as far as i remember i never disabled this option completely)
dram read training - enabled
Ai clock twister - for my hardwares even before i use this ram kits, this setting is always set on moderated. however, i believe depending on hardwares quite a bit, i can't set Stronger when using this 8GB ram and before, and maybe include the voltage setting that also have effect on the setting. i also used to find some cool booting problems with Strong mode

the CPU batch that i got is a very hot CPU on full load, it's the very first retail q9300's that were available in retail store before q9x50, it was some time back in around Mar-April.
my max daily use for this particular CPU have been 467 at its default multi 7.5 and DDR1120, this is for me to keep a low voltage use in system, include RAM,
but 480FSB still can be stable on this p5q-d board. i might rebuild the cooling system if i'm not too lazy and start to use 475FSB for daily setting.
