I take out the dedicated physx card and POST is back and visible.
I think i might have messed with the PCI/PEG setting but i changed it back and its still doing it.
Any Ideas?
Congratulations OP Ochman!

It's PROBABLY showing your BIOS screen on the physx card. Try plugging your monitor into that card and then change the settings on the PCI/PEG to what it was before. thumb.gif

Good luck!

Well, my friends... it's been done. I've listed my P45 rig for sale on CL. frown.gif

I'd put it up here, of course, if I had the 35 rep, but just don't yet. Boosox. Ah well. We'll see if I get any bites on CL... I have to admit... I'm crying inside. frown.gif

Hello guys. I guess I'm welcome here with my Asus Maximus II Gene and P45 Northbridge smile.gif

I've recently bought a Q9450 2.6GHz 12MB L2 Cache for it coming from a Budget E5800 'Pentium Dual Core' processor. And I must say wow.
Before this processor the highest possible FSB I could ever achieve on this board with the budget processor was like 340MHz, and 400± with an even older E6400.

I've successfully managed to achieve a 12-hour Prime95 stable 480MHz FSB and IntelBurnTest stable for 30 minutes. The hardest part was to find the right CPU clock skew and GTL values but I managed to get it rock stable. Memory is currently still on 1:1 ratio so thats like DDR960 effective. I'm now trying to get the ram to run above DDR960 to DDR1150 with different memory divider/ratio.

Before I go and fully tune the processor's clock speed with the required amount of voltage I'd really like to get the FSB/Memory part of my system as fast and stable as possible. But I do know that I can easily manage 3.6GHz with only 1.168v Vcore. So I'm pretty confident that 3.8+GHz shouldn't be a problem at all.

For now I'm going to try and pump up the memory a bit to get it to run stable at 480MHz FSB with 2:3 ratio or something and I've almost got it stable with some timing tweaks. When my system is finished I'll drop a template here it might perhaps help other people.


This system feels like a new i5/i7 computer!

thumb.gif

(I really wish I could reach a stable 500FSB but so far I've had little luck. I've managed to boot it up even at 515FSB with some tweaks but I forgot how I did that (LOL) after 470Mhz FSB the board gets really sensitive to CPU clock skewing and at my stable 480FSB the only working option is a delay of 200ps. 1 option lower or higher doesn't even let the system boot.)

Welcome!!!

Great dude,you're doing it right!!! thumb.gif

I always say :

1. First tune your max FSB (with 6x CPU multiplier),test it with P95 Large FFT..

2. Then up multiplier to what you want and add Vcore,then test it with Intel Burn Test..

480MHz FSB stable in Prime 95 is great with C2Quad processor,it requires a Top end P45 motherboard with advanced CPU GTL and NB GTL options in BIOS..


Great job.. wink.gif

CHEERS..

Haha thanks for the confidence. The only thing that worries me a tiny bit is the FSB Termination voltage. The absolute minimum on 480FSB is 1.34v with tuned GTL Reference voltages but I'm not sure if this is an appropriate amount of voltage for a 480FSB compared to others.. Still the Intel Documents for my specific quad core states that 1.4 (or 1.45v cant remember exactly) is the absolute maximum.

Yeah, just make sure the boards not running too hot, that's not too bad. Pretty sure mines at a bit higher then standard too for 425FSB

On my P5Q Pro, I had FSB Term voltage and NB voltage both at 1.2V @ 450MHz FSB, and I think even at 466MHz too.

In this club, we like to say no higher than 1.4V on either NB or FSB for safety. thumb.gif

I'm currently on a P5Q3 Deluxe, and running 533 FSB with ~1.34V on both NB and FSB, if I recall correctly. However, I haven't messed with GTL options at all yet, and its not completely stable. Do you mind sharing your settings for GTL options? I have no idea where to start with them lol. Note that the P5Q3 Deluxe is a DDR3 board though.

Well I have a big fan at the side of my case which blows cooler air towards the NB heatsink and the mainboard itself so thats pretty sufficient. NB temperatures are 60-65c idle and increases to 70± under load (Blend prime95 test/memtest)

Well it seems I've got it running pretty stable at 480FSB/576Mhz Mem (DDR1152) at 6-6-6-15 timings. I suppose thats still better than DDR2-1066 which (I believe) generally runs at 6-6-6 anyway. I could drop the Performance Level from 10 to 9 with the different Ratio. Running some preliminary tests to see how it goes.

Memory voltage at this speed is a surprising 1.9v at the moment which seems pretty stable. That would almost make me believe the memory can run even higher then 1152 but the first next FSB/ram ratio puts it to 1400+ so thats a tad too high hehe. I will leave it at this for a bit and do some memtest passes.

The one and only timing I really had to change (besides 5-5-5 to 6-6-6) was the READ to READ Delay (S) from 4 to 5 (or possibly 6). Any other timing had no effect at all, so those might even be decreased without stability loss. Upping the voltage had no effect at all, even 2.25v which would probably even make the memory more unstable didn't help, only that specific timing. Took a while to figure out but the results are pretty encouraging.

Sure. But I think the specific GTL Ref voltages are totally dependent on the CPU and are probably totally different with every CPU, even when having the exact same model. But here are my current GTL voltages anyway based on my current VTT of 1.35v;

GTLREF0: +50
GTLREF1: -10
GTLREF2: -50
GTLREF3: -10

A note on the GTLREF2: This was really a very sensitive adjustment and unless it was close to -50 the system kept freezing. GTLREF3 at the other hand was not that sensitive at all, and it could boot and keep itself stable for a big while from -75mV to +75mv± so for that adjustment i just took something in the middle like -10mV. It could be because Cores 2/3 are less important then Core 0/1 since core 0 is probably most utilized anyway when booting up the machine and all that.

Its nice to see how both Die's (0/1 and 2/3) both need different values. +50 and -50 for the first Die (0/1) and -10 and -10 for the second die (2/3) since the processor is virtually just two E8400's or something, not exactly sure.

I could perhaps give you a easy and fast way to get a nice starting point for your GTL ref values though, not sure if its really accurate but it seemed to work well for me;
First find out a near-stable setting at a desired FSB speed, lets say 475MHz FSB and then pump up the FSB voltage to something decent like 1.35v. Then you could do the following method for getting a start on the values;

Put all the GTL's on Auto and first start with the ADDRESS values (should be GTLREF 2 and 3) and tune them one by one and start at +155mv (or the upper limit) and go all the way down to -160mv and see where it boots and where it doesn't. Write the values down and then take the sweet spot in the middle of the upper and lower boot limit.

So an example with adjusting the GTLREF 2 or 3 for instance (Both ADDRESS, I start with these values because these values seems to freeze the system the most instead of actually giving out errors in prime95 for instance);

+125mV (The upper limit for the system to boot and keeping it stable while going throuhg the bios setting.)
-45mV (The lower limit for the system to boot and keeping it stable while you can move through the bios selections)

Now I just took the sweetspot value between these values so I had an average value which +should be a stable starting point to further tweaking it. 125 minus 45 = 80, then we devide that in 2 so the result = +40mV.

I hope that make any sense.
Sorry I didn't have much time posting this so if it's not entirely clear I can elaborate.

So just start with the two ADDR values which are shown here, so you know what GTL's are which (Just in case wink.gif

And afterwards begin to tweak the DATA values as I've described above. At least you have a starting point now. The ADDR value are much more sensitive here and at least here its easy to find out if where and when the whole system freezes because of it. The DATA values seem to reflect more errors in prime95 rather then freezing the whole system. I use the ultimate boot cd to quickly start up prime95 and return to the bios after a successful test.

Changing this setting also helped me in the past, in a similar way. It let me lower voltages a good deal. smile.gif

Ok, thanks. I know my settings will very likely end up being different than yours, but I'm rather confused on what to do with them and appreciate you giving me a place to start. Here's your first +REP. thumb.gif

Np and thanks smile.gif

Let me know if my method is of any help to get you where you want. It might work but then again it might not smile.gif
It's my own way to get a starting point for further tweaking. I mean, you need some sort of reference point to work with anyway.
However some things are just based on feeling and cannot be properly explained by text and descriptions but you'll probably know all about that as a overclocker smile.gif

Well for my own bit of overclocking, memory seems stable now at 576Mhz (DDR1152) after a slight voltage bump to 2.10v with 10 full memtest passes and a lot of individual loops for test #3, #5 and #8 where it showed a couple of errors. I might try and lower it again and fiddling around with the DDR reference voltages since they were optimized on 2.2v. I don't want them to overheat although they do not get hot enough to burn your fingers on without any active cooling on them though. (More like the edge of hurting/not hurting my fingers. I'd estimate a 25% heat increase before saying 'Ouch tongue.gif But I do this on purpose without any airflow to make sure they cannot give any errors during hot summers smile.gif
