Please, could someone give me some brief info about what the differences are between the different boards in the P5K series? I know that some have 2 x pci, and some 3, and that the P5KC supports both DDR2 and DDR3 RAM, but that’s about as far as I’ve gotten after hours of reading and comparing. :/ 

Also, what does the various letters stand for? (You don’t have to explain ”WIFI”, I understand that one.) ;) 

Anyway, here are the boards:

P5K (has 3 x PCI )
P5KC - (both DDR2 & DDR3 RAM)
P5K/SE (2 pci)
P5K/WS (2 pci2.2)

Thanks for reading. Hope someone will help.

Ok from basic board through to more complex.

P5K-SE - Basic 1 x PCI-E x16, 3 x PCI-E x1, 2 x PCI
P5K - has two 16x PCI-e , one 1x PCI-e and 3 pci
P5KR - Adds more Raid options with Intel matrix storage
P5K-WS - Removes a x16 slot for a PCI-X slot
P5KC - Same as P5K except support DDR2 and DDR3
P5K64-WS - Same as P5KR except 4 x PCI-E x 16 slots, 2 x PCI 2.2
P5K-E/WIFI - Same as P5KR Adds Wifi, Firewire, optical out, and more copper
P5K-Deluxe/WIFI - Same as P5K-E Adds another RJ-45, and more copper
P5K-Premium/WIFI - same as P5K-Deluxe
P5K3 Deluxe/WiFi-AP - Same as P5K-Deluxe except has DDR3 NOT DDR2
P5K3 Premium/WiFi-AP - Same as P5K3 Deluxe/WiFi-AP except 2 more USB's and HEAPS of COPPER
Blitz Extreme - Same as P5K-Premium/WIFI except no Wifi 2 more USB and COPPER with ocing ffeatures - ROG

The Premiums are supposed to use better materials: capacitors, mosfets, etc.

It was my first choice but I had to return it because of SAYA-2 issues. Apparently this is still not fixed and no words from Asus so far.
You can read the complaints from this Asus Forum:

Strange that these issues are confined to the Premium boards... you would think they would be able to fix it quick.

Too bad, I really like the P5K-Premium. I checked everyday for the fix.

This is not a small problem because many of us could not even install OS. The facts that this has been going on for a few weeks and Asus still has not given any official words make me think that this is not a simple BIOS fix. This looks like a hardware issue and Asus has not decided how to deal with it. Imagine the number of RMA and what it does to its good name!

the only board i am surprised about is ASUS P5KE PREMIUM ,it has onboard 2GB DDR3 RAM but has no expansion slot for any other ram(it is limited to 2GB ! )

i love my P5K-E too , very nice board :D  )

I am not familiar with the P5K-E but many people around here really likes this MB. Does this P5K-E use high quality material, like the P5K-Premium?

How does this compare to IP35-Pro in term of stability and reliablity? After building the PC, I will not upgrade for a few years.

All the capacitors on both boards are the same. So there cant be too much difference

Besides i here the P5K-Premium has issues with SATA HDD

Yes, I am one of the victims who bought P5K-Premium and spent 12 hours to install Windows but failed. I ended up returning the MB.

This is why I have to look a new MB. I like my new build to be quiet so lots of heat pipes would be nice. Depending on the availability of the X38 MB, I may end up with IP35-Pro.

Going back to the original subject.

What are the differences between P5K-Premium and P5K-Deluxe? Features of the boards like the same to me.
September 22, 2007 10:16:58 PM

The only ones i know of are listed in my first post
September 23, 2007 3:08:07 AM

Strange. Why would Asus sells the same board (or similar in all ways) under different names, different packaging in the same market?

I am asking because since P5K-Premium did not work out for me, maybe the Deluxe would fit the bill.
