"ASUS P5Q Deluxe discussion".

[Dalten]

P5Q Deluxe rocks. I have virtually no vdroop at all. 1.3000 set in BIOS, 1.296 reported by CPUZ under load.

Currently running my X3350 @ 470 x 8 w/ 1.3000 v in the BIOS. 3 cores are stable with lower voltage but the 4th core always crashes p95 so I'm still finding stable settings for 3.8ghz.

Thanks
it helps i still have AI Clock twister on auto and going to do some stability tests now

Thats what I wanted to see.

Guys , what can the Maximus 2 do that the P5Q deluxe cant ?

[Cob]

Slightly is a bit of an understatement. I have LLC enabled with my q6600 @ 3.62ghz.

1.381v bios
1.408v idle
1.424v load

I like LLC because it lowers my idle temps from having to use 1.5 in bios to get 1.42 under load

That's ok until you try to understand why your 24 hour Prime95 stable rig is unstable at idle.

[Iannis]

New mobo for me with Q6600

400 fsbx8 multi

Why core temp appears ok and CPU-Z wrong

[Leeghoofd]

You still got EIST on mate in the bios... it drops down to 6x multi when CPU is idle... do you need 1.39Vcore for 3.2Ghz ? LLC enabled yes or no ?

Leeghoofd - hi mate , what do you reckon ?

[Leeghoofd]

Dunno mate, I don't have the MF II, but next week my mate will have his 2 4870 cards and he will test them on his P5Q dlx, hopefully he can deliver us some good news that the Tweaktown review was a bit over the top... I like my board with a single card solution... totally amasing to me... P5K Dlx revisited for me...easy setup and reliability... and coming from an Nvidia mobo you will be pleasantly surprised

Now LLC is enable and disable some Intel throating technologies

Solved

Thanks man

I will post later my bios settings

How I will go higher with muskin 800MHz 5-5-5-12 memory
Triyng with all straps I can go higher than 400 fsb and KEEP MEMORY AT 800 MHz

How do you know if your computer is stable at load but unstable at idle?
I never shut my computer off and it has been sitting on idle for about two weeks. What do you use to test idle stability?

[Cob]

You can't test for stability at idle, other than letting the machine sit idle.

[Iannis]

How I will go higher with muskin 800MHz 5-5-5-12 memory
Trying with all straps I can go higher, with 8 multi, than 400 fsb and KEEP MEMORY AT 800 MHz 1:1

any suggestion?

[iboomalot]

best Bios so far is ???

[Cob]

No real differences from 0702 onwards.

[aussie-revhead]

.. P5K Dlx revisited for me...easy setup and reliability..

That sounds good to me , I think I will order one .

Just installed 1 4870, getting around 17k 3d06 with cpu at 4250mhz. Got another 4870 sat here but dont wanna try to run 2 with PSU in sig so will have to wait till a new one comes next week.

Guys, the values of overvoltage of this mobo, that the jVIDIA posted a few days ago, is occurring in the same way in these new bios?
You check bios 0803, jVIDIA?
thanks!

Just finishing measuring the voltages of the 0901.

All stays the same as my previous overvoltage readings with the 0702:



But I downgrade back to 0803 because I feel it more solid than 0901.

[Paodaf]

Thank you for information,
is it mean putting a min.voltage value on this mobo leading to serious overvoltage? also for SB and PCIE?

[truehighroller]

What are the pullins for?

Thanks mate!
So i will flash the bios to 0803. you don't test thios bios (0803) about these readings yet?
I don't have a DMM.
And, I do not know how to use it
If I had one, and use knew, I could help you with these readings

[Tirade]

Hey guys and hope you can help.

New install E8400 and P5Q Pro using 2 X 2GB Corsair DDR2800 PC6400 5,5,5,18 1.9v

Everything runs fine at default, all stress testing is ok.

I made only a few changes. Just taking FSB Freq to 400 (which my RAM is rated for) and rasing DDR Volt to 2.0.

I can not get through memtest w/o errors. I lowered CPU ratio so CPU is not at 3.2ghz. I tried raising DDR volt 2.1, and no help. I also tried using DDR slots 2/4 instead of 1/3.

This RAM ran fine @DDR800 in previous P5B 965 board. What should I try next? I really don't think the RAM is bad.

Edit: I changed all the voltages from AUTO to the "defaults" I found in this thread (or close). I lowered CPU ratio to X 7 so Im now running 2.8ghz. I'm not sure if changes the voltages fixed it or dropping the CPU down below stock speed. Either way I just completed 1 pass of memtest w/o error. I will let it run for a bit and see what happens. If I increase the CPU speed, is the CPU voltage the only thing I should raise? I'm on water cooling and it seems that 55c is max load temp currently.

SB and PCI-E I don't know yet because I don't know where are the reading points for those two values.

Anyone knows that ?

Thanks mate!

The 0803 is 99% the same.

What are the pullins foir?

[-n7-]

What are the pullins foir?

I believe they are almost the equivalent of running one notch lower tRD (Performance Level).
I know they affect Everest scores about the same was as dropping to one lower tRD notch anyway.

So in my case, i run tRD 8 + all pull-ins enabled, since i cannot POST if i run tRD 7.

[-n7-]

Well, i've spent hours & hours changing timings & rebooting, running HCI & rebooting...etc.

Doesn't really help that i've updated bios pretty much every time a new one is out.

There are three sets of subtimings on this mobo, & unfortunately for my tweaking, one (or a few) of those timings affects HCI Memtest stability in a big way.

So i'm presently running the 1st set manually set to the same timings as auto puts them at, & the second & third set i've set one notch looser for each one, since auto sets one (or more) of them a wee bit too tight...just haven't figured out which one(s) wrecks stability...there's only like 12 to pick from

One thing i am happy with is how much lower i've been able to drop NB voltage & vDIMM.

I've gotten to somewhere i'm pretty happy with in terms of performance, but also stability, though i'm still going to eventually try to figure out which of those remaining 12 subtimings prefers being set looser.

Gotten my Everest score up a bit too, & on stable settings.
I can get it quite a bit higher, but it'll fail HCI then...

Thanx everyone for the help again; i'll continue to tweak
