"ASUS P5Q Deluxe discussion".

[Hydrus]

With those settings it cannot boot even with a dual core E8400.I used nb vtt and pll auto to run it stably.I will try tomorrow with the q9650 at auto(pll vtt nb) to see if it will boot.I want to ask you if the 1.03g rev is good.And also what bios to use?I already have the latest 2201.Is it ok?

[*GiZmO*]

Hello! I`m wondering,which bios is top at the moment for Asus P5Q Dlx?I have some problems with booting and the picture freezes sometimes on a NV GTX 275,and I assume,there is a bios issue...

[Hydrus]

Well i faced an unexpected problem.My motherboard died and i replaced it with a brand new!Well my friend Leeghoofd i used your settings and now it works great.It seems that my old mobo was faulty.Anyway...now can i try it with a higher multiplier (9)or i must use these settings for sometime?

[scharnhorst]

Hello,

sorry to ask but I'm not sure to understand very well the settings of GTLs.
I've got a P5Q deluxe + Q9650@4.23 GHz
I'm currently using the followings settings;
Vcore ; 1.29
Vfsb ; 1.28
CPU PLL : 1.52
GTLs CPU; 0.680 / 0.720
GTL NB : AUTO
As you can see I'm using high GTL. Is it risky?
I wouldn't like to use settings that could damage my CPU or my Mobo
Please any help would be appeciated.
Thank you in advance

[In-Fluence]

GTLs are more of a fine-tuning thing mate. No cause for concern That's quite a nice overclock you got there too

[scharnhorst]

Thank you very much for you help.
Unfortunately I don't understand why it so hard to get a higher FSB than 470MHz
Moreover even at 467MHz I can't use anything else than ratio 1:1. I though that with Gskill PI black 8500 I would be able to reach more than 1066 but no.

[In-Fluence]

Have you manually set your memory timings (as listed in bios) and lowered PL, clock twister, and raised row refreshed cycle time to 50 or higher? Setting all these are crucial for overclocking memory. As for reaching higher FSB, tuning the NB GTL and the CPU/NB skews can also help a lot as well as the settings I just mentioned. If these fail you, fill out a template (available in earlier posts) and I'm sure people will be able to offer some better advice. 470+FSB can be quite hard to acheive in some scenarios, but again, it's hard to tell without knowing all your settings.

Suggestions are in bold. You might find even higher voltages may help you, but i'm trying to play it safe. My hunch is that CPU/NB skews need tuning. Also set all your auto memory timings to match the numbers listed above each of the 3 sections (except Row Refresh Cycle Time, keep that at ~55).
When trying to find which voltages are best, bump up one at a time and make notes about length of stability, and see which ones improve stability...

Thank you very much I will try with your settings ^_^

There is a sticky about GTLs at the top of the Intel section. That thread helped me out a lot. It's a good read.

If anything try a different PL. I run at a PL8 but if I try and run a PL 10 without changing anything else my board won't even post. Also there is no way that you need 1.3+ vNB. I don't even use that with 8gb of ram.

[scharnhorst]

What is according to you (and according to Intel) the maximum but safe value for vnb on P45 for H24 usage?
Thank you

@BababooeyHTJ

Thank you for your answer (I have posted before seeing your message)
With PL8 I can't boot at all. The minimum for me is 10
What is the frequency of your quad?
Thank you

I was suggesting those volts as a measure to ensure there were enough to rule out NB instability. With the NB GTLs and CPU/NB skews tuned, I actually need 1.28v to run 2 sticks of 1Gb reapers at the same FSB/PL as scharnhorst, but to run it stronger/PL7 I need 1.47v, so there is in fact a chance he might need more than that. You can't assume voltage/performance would scale the same for him as it does you..

Asus just released this new U(EFI) bios for this board. Does anybody know anything about this new generation bios and what are the benefits?

Hi Im trying to hit 4.5Ghz with my E8400 E0
So far I could hit 4Ghz with ease but Im stuck at 500 X8
Even if I try to change my multi to X8.5 I'll have to raise a lot of voltage.

The problem is that when I raise my vCore to very high for X8.5 (v1.36+) my computer become really unstable. Symptoms are
1. Random BSOD
2. Could run p95 small fft for hours and when I restart it can't even do 10 sec. (random)
3. When I could do the small fft test for hours, I couldn't even do 1 min blend,even though I didn't even touch my memory settings and voltages that were rock solid when I was doing 4Ghz on the cpu.
4. When I bring down my vCore and multi to X8, the memory becomes stable again.

HALP!

[Leeghoofd]

you prolly need to up the FSB termination voltage to get anywhere above 4ghz , Note that this also changes the the way the GTL's need to be tweaked...
I would try to first get blend stable on 4Ghz...

First thing to check : does the rig survive Memtest 5 and 7 (via bootable Memtest CD) ?

If so enter windows and then run Blend... this needs to be at least a few hours stable... FYI small FFT only checks (mostly) just the CPU

Try the above changes for Blend stability...

[Brandito]

so no one else has tried that efi bios yet???

[Pants-Of-Fire]

While it looks good, there seem to be a lot of bugs with it, such as no overclocking, not correctly mapping memory, having to select boot device every time, etc. It's not ready for primetime, so you'll get a lot of bugs for a BIOS that you may rarely use. It does however boot very quickly, so it may be the way to go in the future.

There is quite a bit of info and some pictures in the thread linked above at the Asus support forums.

No no Lee the setting I posted is the rock solid setting I currently use. What I want is to change the multi to 8.5 and then eventually 9. Yes my memory and cpu are both rock solid with that setting. It's just that I don't understand why my computer acts so random and unstable when I change the multi to 8.5 (I couldn't even try 9 cause I couldn't get 8.5 stable) I didn't even touch vNB,vFSB or anything. I just changed brute vCore for 8.5 to be stable but if I do that, all the sudden, my memory gets affected too? :O? So that is my question. How would I get to 9 multi? I can start from the above settings I assume, because that setting is rock solid for me.

[deaffob]

does my vfsb have to be higher than my vcore to offset this random unstability?

[Leeghoofd]

due to the increased CPU speed it could be that the NB get's a harder time to keep it all together... usually upping FSB term voltage (influences CPU and NB reference votages) helps, but you need to tinker with the GTL values too then... I suggested the above to relax the stress on the NB ( looser ram settings etc) so it's easier to work from there...

For the FSB term voltage, it doesn't need to be specifically higher than the Vcore... I had one CPU that ran at 1.2FSB term voltage at 4Ghz with 1.3Vcore...

Also note that not all CPU's do 4.5Ghz stable (heat generated is the biggest culprit, and the temp readings on most Wolfdlae CPU's are way off or totally borked)...

[deaffob]

Even if I increase the FSB ter voltage, wouldn't AUTO setting pretty much be fine? Also I thought NB GTL is based vNB not vFSB :O

If CPU GTL and NB GTL are both based on vFSB, can't I just increase the vNB like end of the day to get it stable?

[Leeghoofd]

Give it a go and report back... but monitor ya CPU temps !! could be you need over 1.45Vcore to get anywhere...

Make a bootable Memtest CD, test 5 and 7 have to run without errors before going into windows.
In windows always test CPU first ( I do custom 20-20K set and let that run for an hour or so ) then try Blend...

Hello all !! This is my first post on XS
Ok, am think of purchase quad.
And consequently questions
1. Whether can my motherboard stable work on 500 fsb 24/7 ?
2. What processor necessary to buy (cpu ratio) q9550 or q9650 (so expensive ) for my p5q-e? In an ideal I want Q4.2-4.3 Ghz on 24/7
3. What the most successful weeks of release of processors (successful on overclock)
And last question
4. Can i feel the power 4 core's except as gta4?

PS sorry for my bad english
PPS sorry for a little offtop

[Leeghoofd]

Lo Moscow,

if your rams can't do 1200mhz forget 500FSB quad action daily on the P5Q series... Buy yourself a 9550 and you will have 4Ghz for sure... more is all luck: good CPU, High speed rams, Good mobo, PSU , Cooling etc....

Unless you are multitasking or ya apps support the extra cores, you will not feel much difference over ya OC'ed dual core...
