Heads up for folks with PS/2 mouse, these new Asus P5K/P5K3 Deluxe boards removed the mouse PS/2 port in favour of USB mouse devices. So if you have a PS/2 mouse you'd either need to grab a USB mouse or PS/2 to USB adaptor http://www.auspcmarket.com.au/show_p...de]=CB-SKUSBPS. Unfortunately, for me that particular adaptor didn't work with my KVM switch mouse PS/2 connector cable so a USB mouse was needed.
Recovery from failed overclocks seems to be much better on Asus P5K Deluxe. Just turning off from power switch and powering psu off, wait a bit and power psu back on and power up would initiate the recovery mode - I see the bios detecting cpu at default 9x266FSB for my E6600 so i can F1 back into bios to set proper settings. No need for clear CMOS so far
Memory dividers available on Asus P5K Deluxe depend on the FSB Frequency set. Not all FSB Frequencies have all dividers available for them (well for 266FSB at least haven't tested the rest yet).

At 266FSB you have access to DDR2-667 (4:5), DDR2-800 (2:3), DDR2-889 (3:5), and DDR2-1067 (1:2). Photo
At 333FSB there's DDR2-667 (1:1), DDR2-800 (5:6), DDR2-833 (4:5), DDR2-1000 (2:3), DDR2-1067 (5:8), DDR2-1111 (3:5), and DDR2-1333 (1:2). Photo
At 400FSB there's DDR2-800 (1:1), DDR2-960 (5:6), DDR2-1000 (4:5), DDR2-1200 (2:3), DDR2-1280 (5:8), DDR2-1333 (3:5) and DDR2-1600 (1:2). Photo
At 500FSB there's DDR2-1000 (1:1), DDR2-1200 (5:6), DDR2-1250 (4:5), DDR2-1500 (2:3), DDR2-1600 (5:8), DDR2-1667 (3:5) and DDR2-2000 (1:2). Photo
Seems for at least 1:1, 4:5 and 2:3 dividers AUTO subtimings are set pretty tight, performing in Super Pi times just behind manually set subtimings of 3-30-8-3-6.

CPU Voltage Damper option in bios reduces vcore droop by as much as 75%. From approximately 0.032v droop to 0.008v droop! Finally, Asus answers our prayers in regards to vcore droop

Transaction Booster bios option when enabled, seems to boost memtest86+ v1.70 reported memory bandwidth. By default Transaction Booster is set to AUTO, but when Enabled or Disabled a sub menu appears in the form of levels. When enabled, Transaction Booster gives you an option to select 2 Boost levels of 0 or 1. When disabled, Transaction Booster gives you an option to select 3 different Relaxed levels between 0-3 - level 0 at least looks the same as AUTO set Transaction Booster in memtest86+ v1.70 bandwidth.

Interesting to note that for tests at 9x444FSB 1:1 4-4-4-4 2-20-2-2-2 at 2.1v vdimm that Transaction Booster AUTO and TRFC = 20, memtest reports 5383MB/s memory bandwidth compared with TRFC = 25 or 30 at 5201MB/s. But at TRFC = 20 if you enable Transaction Booster with Boost level 1, memtest still reports 5383MB/s. Could it be Transaction Booster Enabled just manipulates a tighter TRFC or other subtimings values ? Without memset for windows we won't be able to see what the subtimings are for real for now though.

Pros:
- CPU Voltage Damper fixes the old vcore droop issue!
- High memory clocking like P5B Deluxe/Commando with upto 2.55v vdimm max
- High Kentsfield quad core fsb - folks been able to get their QX6700 to 480-500FSB compared with P5B Deluxe 400FSB or 450-480fsb with volt mods or 440-480FSB on Asus Commando
- Very good failed oc recovery like Asus 680i Striker extreme, less need for clearing CMOS on failed overclocks
- Cleaner cpu socket area for phase change or extreme cooling users like Asus Commando (my Commando just arrived on Friday so another adventure starting soon - this is for phase change )
- Stock auto performance is very fast on par with moderately tweaked P5B Deluxe in terms of memory bandwidth/super pi. Handles tighter subtimings for memory than P5B Deluxe but performance similar - so maybe loosened up a bit by default for P5K Deluxe.

вот тут вопрос возник - какая просадка напряжения на память? Нигде посмотреть немогу.

ПРО ОТЛИЧИЯ ПЛАТ

раз нигде нет, значит так и есть 2.3V

Один раз после запуска Coretemp0.95 выкунуло BSOD, ни у кого так не было??

точное напряжение можно узнать мультиметром
