There are plenty of mods for this board. Because it uses the P5K Deluxe PCB the mods are the same.

Vmods

VDroop Pencil Mod





Well seeing as I just got this board and could not find an "Official" thread I thought I would start one!

Through various forums there's a little confusion about this board. The P5K-E is a P5K Deluxe PCB. The main differances include one less ethernet controller and not as much copper heat-pipeing.

At this time the 0602 Bios seems to be the most reliable with the recent batch bringing volt issues.

Benching my E6600 tonight and will hopefully have my Crucial 8500's here tomorrow :)

First board I got today didn't boot up, but the replacement seems great so far.

Make sure to cool the vregs well, the stock cooling barely makes contact and if you overvolt at all, they get REALLY hot.

Is it worth taking it off and putting a layer of Artic Silver on there?

Nice to finally see an official thread about this mainboard, there are plenty of users here at XS with this board.

Any word on a new 45nm supporting bios?

It seems the later ones with 45nm support are well bugged regarding voltages.

I like this board a lot, very stable, good overclocking potential but the NB heatsink runs blistering hot with 1.7V on it, i mounted a 40mm fan on it.

Yea, but I would use ceramique or something similar for this kind of application.

What I really want to see in here is how much perfomance is added when you throw another 3870 in for crossfire. I want to get a second one but I'm worried that the x4 will rob it of so much performance it won't be worth it.

Since I'm new to this forum, greetings to all the members :)

It's good to see an official thread for this mobo. I'm just one of (hopefully) happy owners. Bought that one about a week ago and just started OCing (my previous gigabyte had a "no-oc-at-all" syndrome...).

Look out for a new BIOS. A new one (0901) has been provided for a "naked" np-wifi P5K-E recently. Should be a matter of days for us to get an update from ASUS... As for me - I'm still using the one originally flashed (0503) and feel satisfied (knowing about all the problems reported for 0806).

As for the mods... I might not be a keen overclocker (only a modest OC in progress), but with a voltage damper enabled, I haven't noticed any drop so far. On the other hand - voltage on desktop differs from the one set in BIOS by 0.025 (default 1.325 set, for some reason only 1.3 on desktop). I've not tested the voltages with damper disabled (might be a question of that feature?).

And by the way... PECI enabled. BIOS temperature readings look realistic, but PC Probe shows lowered CPU temps (seems to be a common problem reported by a lot of users). Dunno whether it might be accurate for all of you, but it seems that the correct offset for a CPU Temp in SpeedFan (TCase, not cores - these looks to be reported correctly by CoreTemp and require a +15 offset in SpeedFan) should be about 7 +/- 1 degrees.

So far I like the board.
I have it paired with a Q6600

One thing i dont like is where they put the IDE plug.
I like to put my Haupauge PVR-500 in this slot but it is very long and sits right on the cable.

My results from dampner and the pencil mod.

No Mod/No Dampner
1.45 bios
1.41 idle
1.36 load


No Mod/Dampner
1.45 bios
1.424 idle
1.408 load

Mod/No Dampner
1.45 bios
1.424 idle
1.408 load

Mod/Dampner
1.45 bios
1.424 idle
1.424 load



As you can see, Mod + Dampner = no droop at all. It sometimes does move slightly. For example last night when I began Orthos the voltage actually went UP. This may be due to the mod not being done propertly. I'm going to buy a 2B pencil and will reapply today.

New bios 0901 release, anyone tested it, hope it good :D

Is anyone else having issues with onboard sound and headphones? Everything was working perfect whilst listening to music. I just booted up a game and the sound stopped.

Now everytime I stuff around with the jacks the PC freezes. Although I am putting the jacks in the holes it suggests for the headphone profile nothing works.

This is annoying :(

As per this thread, the 0901 was released a few days ago and has the same vdroop issues as the 8 series :(

As far as the Pencil mod... how heavy to shade it, what lead?

I'm asking because I'm considering doing it, but not sure about these parts. Also.. I've seen two different resistors people talk about shading... which one is it?

Guys,

Be carefull with doing Vroop mods.

Vdroop isn't designed to tease the Asus users it there to make up for the lack of a big number of xtra capacitors.

In other words, Vdroop has to there in order to have voltage spiking within specs.

Let me elaborate:

When going from heavy load back to little load or even idle, a voltage spike occures.
Whenever the Vcore droops a bit, the spike will be within specs and do no damage to components like PWM mosfets.

Now doing a Vdroop mod takes away the ability to let the voltage droop under load, causing a voltage spike when going from full load to little or no load that will be out of spec.

The best way to cure this spiking is using caps but since the space around the PWM area on a mobo is limited, there's simply not enough space to place sufficient capacity of caps, that's why Asus came up with this compromis.

Having no droop can cause a mosfet to burn as seen on several occasions here.

Just be aware. ;)

Having said that, i also see there some confusion on Vdrop and vdroop.

Vdrop -- setting for example 1.5V in bios results in 1.45V in windows.
vdroop -- having for example 1.5v idle but dro(o)ps to ~1.45 under load.

Here u are Cf on P5K-E, cards are @ stock:

Does this board clock the same as the P5K premium. I am stuck to a budget and its either the P5K-E the P5K "Basic"

Go with this P5K-E wifi/AP, this one does have the voltage damper function that the vanilla P5K lacks.

Thanks, The P5K-E is basically a Premium without a heatsink then?

Why is that ?

I've had a customer contact me about this board not booting to SATA optical. Has anyone encountered the problem, and do you know what the workaround is? If I can't get an answer I'm probably going to end up pulling a board and testing it to see if I can reproduce the problem, so if anyone knows, please fire me a PM :(

P5K DLX without 1 LAN and some heatsinks...

I've heard of it.. also had some issues. It ended up being boot priorities and what SATA port I had it in.

Had to put it in one of the black SATA ports and then select some crazy HD 2i2w3525 to boot from.. Hitting boot from CD-Rom didn't work.. guess it looked for IDE on that. Having it in the red SATA port when I had RAID configured made it not boot.

Yup boot setting and what sata connector your on.
I believe the black ones are considered slave.

Thanks for the help fellas. I'll see if this clears things up for him.

I've run into these kinds of weird problems before, but I'm not familiar enough with this board to give him a solid answer having not used it.

I also have this board and I'm very satisfied with it. I'm using the 0401 bios, but I think I will try 0602 tomorrow... Anyone know how it works with a Xeon 3060? :)

For some odd reason I get vdroops with my Xeon cpu and 0401 bios. I didn't when I used a E6400..?!

And C0ncrete, thx a lot for your mod/damp results! I'm now considering doing the mod myself! :)
