I think it will support them because you can easily run a 1333MHz FSB right now through manual timings. If you are talking about 45nm Penryn chips, probably not, but who knows right now.

Processor: Intel Core 2 Duo E6320

I've tried different memorytimings, speeds, voltages, slots... but nothing. Most of the times the system wont even reach the bios before it freezes, other times it will work for some hours in windows before it suddenly reboots/freezes.

I got no idea what to adjust. Has anybody tried this memory?

Try running Memtest on each stick individually to see if one is bad. If it checks out fine but won't boot with two I'd probably just return the memory and try something else. I think Newegg has a deal for Crucial Ballistix 2GB (2x1GB) Pc2-6400 for $85 ($45 after MIR) which is an insane price since its Micron D9 chips and will get 1100MHz easily.

@diZrupt0r: I see you're using the beta 1201 BIOS... I've read that this revision changes the vdroop. Can you confirm this rumor?

Since BIOS 1004 it is supported, the 1333 Mhz bus. But I don't think it will support the new CPUs in 45 nm (Penryn).
So I guess if you want to the Core 2 Quad with the 1333 Mhz you will have to see if the core is Penryn or not.

I don't know what are your intentions, but if you want a mobo that supports the Core 2 Quad with 1333 Mhz, I would say to you to go with the new Intel chipset P35 or even wait for the X38, or P38 (I can't remember the name now). It is much more mature chipset, better memory controlling, better performance. And it does support the 45 nm processors.

I'd like to hear about this as well. Is it supposed to reduce Vdroop? I'm getting about 0.05V now at load (set 1.4V in BIOS, get 1.37V actual).

Gramboh,

Dizruptor got the Asus P5B, not the Deluxe model. Just a heads up since you got the P5B Deluxe.
And there is a pencil trick for the vdroop. I can't find here right now. But my friend did it. I will ask him if you are insterested.

I think it's pretty complicated and requires you to pull the board. Please post if it you find it -- I too lost the links I had to it.

I'm having an issue with this board. I don't know if it's bad or if I'm just missing something, but my issue is that I get poor fps in games and my frames drop even more when I OC the cpu.

Here's my setup:

asus p5b deluxe
core 2 duo e6420
corsair dominator ddr2 800 - 4-4-4-12, 2.1v
radeon x1950xt
wd raptor 74gb sata hd
fsp 600w psu

Latest drivers, latest bios, fresh install of xp pro sp2, cpu at stock speed - my 3dmark06 score is 6222. With the cpu oc'd to 3.2ghz (stable) that score drops to 5077.

Memtest ran for 10 hours with no errors. I've tried a different video card, different psu, raising the pci-e frequency to 110, adjusting voltages, tightening memory timings, loosening them and oc'ing the memory, oc'ing the video card, turning various settings off and on (speedstepping, spread spectrum, etc). Still can't oc the cpu without a nasty drop in video performance.

It might be just me being dumb but I'm beginning to suspect that the board is bad. Any ideas?

If you are overclocking your system, probably you are having the x1 problem.
Try to set in the BIOS FSB Termination voltage to 1.40 and the NB voltage to 1.45 I think.
And check with CPU-Z if you getting x16 in the PCI-Ex interface.
And BTW what FSB frequency are you using?

Try that!

Yep, that's it. I've never noticed that before.

Currently I have my PCI-E freq to 112, FSB termination 1.4v, NB 1.45v, SB 1.5v, FSP is at 400mhz with 8x multiplier. PCI-E link width is still showing 1x in cpu-z.

I tried dropping the fsb down to 333. Same thing.

I keep FSB termination , NB , SB at default.
I solve the problem by setting the bios to optimum settings, re-boot. CPU-z will report 16x.
I reboot again and set the bios to my custom settings.

Try to put your pci-e frequency to 105.
Everything @ default should work.
This only happens when you are OCing.
And leave the SB to default. That is how mine is set.
Running 400 Mhz here too.

I have just upgraded an old 939 system to a core 2 duo E6600 with 2 GB of RAM on an ASUS P5B-E MB for a friend whose old MB caught the leaky capacitor disease. He also had to upgrade his video card so he chose the ATI X1950 GTS 256.

Now, I assembled all the components and all that went without hitch but when I turned it on it refused to enter the BIOS setup. All I got was an ASUS splash screen and a few fleeting post messages followed by a blank screen.

I double checked everything but found nothing amiss with my assembly.

I took it up to the store from which my friend bought the components and they found the same thing. I suggested that the BIOS was probably corrupt since I have encountered that on a previous build for another friend so they tried to boot from a floppy to flash the BIOS but it would not even detect the floppy.

He supposedly replaced the Core 2 processor with a P4 of some lower type and got it to boot so that he could flash the BIOS. He re-installed the Core 2 and still it refused to boot. He concluded that the processor was faulty but had to wait a few hours for delivery of some more so that he could replace it.

On replacing it the same problem still existed so it was not the processor at fault.

He then tried to tell me that the power supply, an ANTEC Neo 500 Watt job, was unable to supply the neccessary power for the X1950 which from my experience is a whole lot of rubbish and also he should have realized that it was working with the P4 CPU that he used to update the BIOS.

In a blind stab in the dark he replaced the X1950 with an NV 8600 GT which worked.

It seems that the X1950 will not work on that MB. Therefore my conclusion is that the MB is at fault making the Core 2 incompatible with the ATI video card.

Unfortunately the technician was unwilling to change the MB because it was working with the 8600 and concluded that it was fixed.

My friend argued with him in an endeavor to convince him that the MB was faulty and they should therefore replace it but he is now stuck with it.

I read the following Anandtech article and noted that both P5B-E boards tested used an X1950 XTX video card and used an old BIOS v 0402 so the thing should have worked.

Has anybody struck a P5B-E that refused to run a particular combination of video card and CPU?

This is a new one on me and it really leaves me mystified!

God bless,

Bernie

haha this actually worked. I rebooted, loaded the default settings (via the option in the bios, not the cmos jumper), loaded windows, restarted and set the fsb to 400 and set the memory timings. Works great. Thanks!

I have done it many times with this board. I keep my computer on all the time. But, when I do re boot, The first thing I do is check that. It is a P5B problem. But all you have to do is re-set it.

It happens more if you don't have you PCI X set at 100V. Sometimes when it happens you get 3 beeps then one beep and it re-boots to 1x mode.

I have found no benefit by messing with the Northbridge Southbridge voltage Etc..

Well there is no really benefit, unless your OC is getting unstable. So increasing the NB voltage might help. Otherwise leave alone or you only will get heat!

Can you upload it to a free site like Imageshack and link it here? I remember seeing the picture a few months ago and deciding it was too much of a pain in the ass, I don't want to break down my PC and rebuild it and risk screwing something up (I don't have the most steady hands).

Thanks

I'd like to bring ALL the motherboard (internal) USB ports out out to the back of the machine (bulkhead). Where can I find the correct assemblies for doing this?

Thanks - Jim

Thanks Rafael. It doesn't look so hard afterall. Maybe if I get bored this summer I'll take apart my PC try it, and rebuild it. I want to try reseating the heatsink anyway.
