Modded ASUS P5Q/Pro/Deluxe/Premium BIOS

[Ket]

The part number of the sticks is OCZ2N1066SR1G and they are 2 x 1GB kit . Do we have the same? Have you ever tested them with the P5Q PRO?

Oh man you maybe be the first person i meet on the net to have a P5Q PRO and some same memory as mine. lol I had started to think that i would have better made a research for what memory most P5Q PRO owners use before i made my purchase. In fact i didn't know that G.skill or Crucial was so famous.. I thought i would find more people using OCZ memory

Yep thats the same OCZ kit as I have. I wasn't looking for memory that clocked really well, just something that was fast stock and maybe had enough wiggle room to go to ~1150MHz. After 5 RAM kits I'm convinced the memory I have can't all be crap clockers, and theres another limiting factor somewhere.

First off Ket of to you my good man. Second i got all the settings on auto at the moment i know youve said it might be better leaving them loose but do you think i should try to you know configure them again and take them off auto might increase in performance ( might ). I really wanna do 5-5-5-12 on these Mushkin Ascent Redline 8000 kit i got it running at 1066.

I set some timings manually, but for the most part other timings are best left at auto anyway.

Do you mean that you have tested OCZ kits with the P5Q PRO and there is a limiting factor somewhere else but the sticks themselves? When you say 5 ram kits you mean five OCZ2N1066SR1G kits?

I'm currently running those OCZ2N1066SR1G at 1154Mhz with 360FSB (5:8 ratio) and they are stable. But as i said raising the fsb (and as a result, memory write bandwidth) there is instability with blend stress (large fft).. Do you mean the same?

If high memory write bandwidth is the cause of the instability with certain memory modules then the only thing i can think of as the cause of the problem is inappropriate timing settings set by the motherboard (because there are some timing options that cant be set by the bios. even with manual selected ofcourse).

Not 5 OCZ kits no. I thought the P5Q series was just very picky about what RAM it would play nice with, thats seems to not be the case tho I have tried to date;

Patriot PC6400 4-4-4-12 (works great @ 1066 on a AW9D-Max) on the P5Q series the system won't even POST with this kit.

Geil Golden Dragon PC6400, I'm sure on any other board this kit would do 1066+, on the P5Q series it boots all the way up to 1100+ but isnt stable even @ 1029

OCZ SLi kit, constant problems with the memory, booted 1143MHz, not stable. Again I think this is a P5Q series BIOS issue.

Mushkin PC8000 D9GMX, booted 1143MHz, not stable.. (noticing a pattern here yet?)

Cellshock PC8000 D9GKX, boots up to 1206MHz, not stable even @ 1143MHz seemingly..

The only explanation to all this I can think of is my CPU and the P45 not actually being properly tailored for 65nm CPUs.. that or asus partially fudged 65nm support. Even on a AW9D-Max I can run my "lowly" E4400 on a 400 strap @ 425FSB, absolutely perfect. What happens when I try setting 400 strap and memory divider on the P5Q boards? No POST. Well done Asus /sarcasm.

The timings you can't set in BIOS are not a huge problem, this is where spdtool comes to the rescue, you can loosen things like trc via the spd data and reflash the modules. The only pain in the arse is that w1z still hasn't added P45 support. Bad w1z, bad bad w1z

Theoretically loosening trc for intel boards should allow for better stability and higher frequencies.

This is a customised spd data file for those OCZ2N1066SR1G. As your probably aware spdtool is absolutely bloody useless on P45 boards currently However you can use spdtool on just about any other platform. Let me know if the modules play nice

my new pq5-e from newegg is a rev A3 on the north.

so far all bios work fine for me on loadline. without it i get massive vdrop/droop. with it on.. it over volts alittle on load.

Ket please drop me a PM with a changelog for this file if you can. Also please come thru me if you find a bug in SPD, im open to all help but I like to keep customers warranty in tact.

Woot ! When you say customized you also mean optimized timings or rated timings from OCZ?

Sadly i dont have any other platform to test them so... i'm waiting for an update of spdtool to recognize P45. I hope configuring timings from SPD bytes will fix stability problems.. Does EPP contains more settings than SPD? Or it's just a marketing renamed SPD?
