After setting up my P5K Deluxe the other night, I decided to start off with my old trusty E6600 B1 ES and then move onto my Q6600 Kentsfield quad core cpu so as to be able to compare temps and results with my other motherboard adventures with the same cpu. The P5K Deluxe shipped with 0123 bios but was updated to latest 0304 bios and flashed using USB drive and Ez Flash 2 in bios. You can see the bios screen shots here. Asus P5K Deluxe Photos             Notes: - Will be continually updated as I progress.
Flashing bios on Asus P5K Deluxe: Asus P5K Deluxe uses 2MB sized bios flash ROMs. So best way to flash or update your bios on Asus P5K Deluxe is to use a USB flash drive and the motherboard's own inbuilt EZ Flash 2 function:
  Preliminary conclusions May 13th, 2007: Asus P5K Deluxe is meant to be replacing the 965P chipset motherboards such as Asus P5B Deluxe/P5B-E etc with the flagship 975X chipset being replaced by Intel X38 chipset due out later. I think the Asus P5K Deluxe can potentially end up faster in memory bandwidth intensive tasks than 965P by virtue of the new dividers available 5:6 and 5:8 opens up alot more FSB/MEM combinations  So far i can say, Asus P5K Deluxe has all the good features of Asus P5W DH, Asus P5B Deluxe, Asus 680i Striker extreme, Asus Commando and Asus P5W64 WS Pro rolled into one Asus took alot of feedback into consideration when they designed P5K Deluxe it seems (some suggestions i put forth but I've sure other end user folk have put their 2 cents in too  )Pros:
Cons:
But those are preliminary conclusions.. only had the Asus P5K Deluxe and P5K3 Deluxe board for 4 1/2 days so far The Asus P5K Deluxe isn't officially due out until later in May/June it seems, but alot of Australian retailers have started listing the motherboard just under AUD$400. Some of my favourite retailers include:

| Administrator | Re: Asus P5K Deluxe - Intel P35 Bearlake + Intel E6600 B1 ES CPU Voltage Damper Option The Asus CPU Voltage Damper option in bios when enabled reduces vcore droop under load by alot it seems - ~75% reduction in vcore droop under load when enabled! 1.425v bios set in windows AI Suite reports 1.392-1.400v idle and 1.368v drooped under load by 0.032v. But with CPU Voltage Damper enabled, AI Suite reports 1.4080v idle vcore and 1.400v load vcore - only 0.008v vcore droop! Other bios set vcore options have similar reductions to only 0.008v vcore droop under load when CPU Voltage Damper is enabled CPU Voltage Damper disabled @1.425v bios set vcore = 2.2857% vcore droop under orthos small FFTs load CPU Voltage Damper enabled @1.425v bios set vcore = 0.5682% vcore droop under orthos small FFTs load  |

The P5K Deluxe handled my E6600 B1 ES much like my P5B Deluxe did needing slightly more vcore (1.416v loaded) to run Orthos stable compared to E6600 B1 ES on Asus P5W DH Deluxe motherboard (~1.38-1.39v vcore loaded).

| Administrator | Re: Asus P5K Deluxe - Intel P35 Bearlake + Intel E6600 B1 ES Asus P5K Deluxe Timings/Subtimings 1:1 Memory Divider I went back to look at my usual P5B Deluxe advance timings and decided to see how they relate to what P5K Deluxe offers so as to see what kind of advance timings I can start off testing with. After comparing them, I figured I'd start with same advance timing defaults as P5B Deluxe. For P5K Deluxe:
I'll use Super Pi v1.50 to showcase how much difference adjusting memory timings and subtimings has on bandwidth intensive applications performance. Important to note, when looking at the Super Pi times, is that using E6600 B1 stepping ES cpu the Super Pi times are approximately 10-22 seconds slower clock for clock than retail Core 2 Duo B2 stepping cpus. I'll swap to a retail B2 stepping cpu after I used my E6600 B1 ES cpu to figure out the memory clock/timings behavioural characteristics of the Asus P5K Deluxe. I'll start off with all sub timings being set to AUTO:
 Then we'll tighten just tRAS to 4 but leave everything else the same (largesystemcache disabled in Windows XP Pro SP2):
 Then tighten subtimings to P5B Deluxe default values (largesystemcache disabled in Windows XP Pro SP2):
 Then tighten subtimings even further (largesystemcache disabled in Windows XP Pro SP2):
 How tight can we go still at 2.1v vdimm (largesystemcache disabled in Windows XP Pro SP2):
 Easier chart comparison:  Important to note, when looking at the Super Pi times, is that using E6600 B1 stepping ES cpu the Super Pi times are approximately 10-22 seconds slower clock for clock than retail Core 2 Duo B2 stepping cpus. Edit: It seems I had largesystemcache disabled in Windows XP Pro SP2 which might account for the slower times  I'll rerun the last configuration of 4-4-4-4 3-30-3-3-3 again with largesystemcache enabled in Windows XP Pro SP2.Largesystemcache enabled time is ~25 seconds faster:  From the above Super Pi 1:1 memory divider testing, we see that AUTO subtimings set are at least faster than 6-42-10-10-10-10 (AUTO subtimings 0.955% faster) but slightly slower than manually set 3-30-8-3-6 (AUTO subtimings 0.378% slower) and 3-30-3-3-3 (AUTO subtimings 1.098% slower). I'm guessing that AUTO subtimings' values are a bit looser but close to 3-30-8-3-6 manually set values. Update: May 22, 2007 Use of B2 retail core 2 cpu Here's an update using a retail B2 stepping cpu to show the differences in times compared to my E6600 B1 above.  Using 9x400FSB 1:1 settings below:
@400Mhz 5-5-5-8 at 2.1v  @400Mhz 4-4-4-8 at 2.2v  @400Mhz 3-3-3-8 at 2.3v  Looks like difference was more than 20 seconds more like 40+ seconds! |

| Administrator | Re: Asus P5K Deluxe - Intel P35 Bearlake + Intel E6600 B1 ES Asus P5K Deluxe Timings/Subtimings 4:5 Memory Divider Next up is looking at how 4:5 memory divider behaves on Asus P5K Deluxe using 0304 bios. First feature I noticed was that changing memory dividers also triggers off the the auto shutdown and auto restart process on only the bios exit in which you change the memory dividers. This is normal in order to properly set up the settings and only happens on the first change of memory dividers at exiting bios. Second item I noticed was there might be a bug in that PCI-E Frequency isn't locking properly when set to 100Mhz on first boot up after changing to 4:5 memory divider. Setting PCI-E Frequency to 102Mhz fixed the problem completely though. I've passed this finding onto Asus folks so let's see what they can do for the next bios release. For 4:5 memory divider testing right now, I just wanted to find out what the bios set's for AUTO for the subtimings as memset doesn't support P35 Bearlake chipset as yet there's no way to know from within windows what AUTO values are used for subtimings. I decided to run 2 sets of tests, one at AUTO subtimings and one at 3-30-3-3-3 manually set subtimings.
 Manually set subtimings (largesystemcache enabled from now on):
 Important to note, when looking at the Super Pi times, is that using E6600 B1 stepping ES cpu the Super Pi times are approximately 10-22 seconds slower clock for clock than retail Core 2 Duo B2 stepping cpus. However, even for B1 stepping cpu it seems the 32M times are off a bit from past B1 times at 4:5 on other boards, I'll have to pluck in a B2 stepping cpu latter to see what's happening.  Again a similar pattern emerges as with 1:1 memory divider test in that manually set 3-30-3-3-3 sub timings is only 0.437% faster than AUTO subtimings configuration. In other words, AUTO subtimings values even on 4:5 divider are set pretty tight to begin with. This maybe good if you have a nice pair of Micron D9xxx based DDR2 memory with adequate vdimm memory voltage but might be too tight for other value memory. I'm not sure if AUTO subtiming values are set by the memory's SPD programming ? If that was the case, then how fast or slow AUTO subtimings are would be dependent on your specific DDR2 memory modules' SPD programming ?? For value ram 4:5 divider mode, maybe it might be easier to start off with manually set subtiming values to 6-42-10-10-10 since it's alot looser and work your way down to tighter values ? |

Like the 4:5 memory divider tests, I'll run 2 sets of tests, one at AUTO subtimings and one at 3-30-3-3-3 manually set subtimings.
 Manually set subtimings (largesystemcache enabled from now on):
 Important to note, when looking at the Super Pi times, is that using E6600 B1 stepping ES cpu the Super Pi times are approximately 10-22 seconds slower clock for clock than retail Core 2 Duo B2 stepping cpus.  Again the same pattern as with 1:1 and 4:5 memory dividers in that AUTO subtiming values in 2:3 divider mode are already set pretty tight out of the box. Auto subtiming values are only 0.251% slower than manually set subtimings of 3-30-3-3-3. . |

Just doing some quick screenies at 7x501FSB 1:1 and also checking out Super Talent PC2-8000 memory with the new 5:8 divider available on Asus P5K Deluxe @614mhz 5-5-5-5 at 2.45v 7x501FSB 1:1  5:8 divider @614mhz 5-5-5-5 at 2.45v  That's 9mhz better than on Asus P5B Deluxe with same memory @605mhz 5-5-5-15 6-42-11-10-10-10 at 2.45v IIRC! Important to note, when looking at the Super Pi times, is that using E6600 B1 stepping ES cpu the Super Pi times are approximately 10-22 seconds slower clock for clock than retail Core 2 Duo B2 stepping cpus. . |
