2x1GB Twin2X2048-10000C5DF Dominator
Asus P5K Deluxe 0311 bios

I decided to revisit my 2x1GB Twin2X2048-10000C5D Dominator memory rated at DDR-1250Mhz 5-5-5-18 at 2.4v (kindly supplied by Corsair ).

Originally, even with 0311 official bios the 10000C5D Dominators were a bit more than flaky on P5K Deluxe - understandably so as 10000C5D Dominators are validated only on eVGA 680i motherboards. But it seems now that I am retesting them in black dimm slots instead of yellow dimm slots, they're alot more stable particularly at 4-4-4-x timings needing less vdimm and clocking a bit tighter on memory timings in black dimm slots than in yellow dimm slots!

Note, prior to these tests all my 2x1GB memory testing to date on P5K Deluxe has been in the yellow dimm slots.

System

• Q6600 QUPT B3 ES
• Corsair Nautilus 500 3/8" ID
• Asus P5K Deluxe 0311 official bios
• 128MB Gainward FX5200 PCI
• 2x1GB Corsair Twin2X2048-10000C5D in black dimm slots
• 74GB WD Raptor 8MB on SATA 2 port
• Pioneer DVR-08 Burner
• Sony FDD
• 1KW PCP&C SLI psu
• WinXP Pro SP2

I managed to pull off some quick tests for low clock Super Pi Challenge @3600Mhz and managed my fastest Super Pi 1M and 32M times to date for a quad core Kentsfield Q6600 cpu

Super Pi 32M


From my experience on Asus P5B Deluxe, quad core kentsfield B3 stepping is around 10-20 seconds slower clock for clock than core 2 duo B2 dual core cpus. And even my personal best E6700 B2 dual core time on P5B Deluxe @3600Mhz is only 13min 08ish.

Will have to do some more tests with black dimm slots it seems

Edit: okay confirmation from bingo13/Gary from Anandtech here, black dimm slots are designed to do this according to Asus!

Edit 2: Yup can confirm now black dimm slots rule for 10000C5D Dominators on P5K Deluxe

Black dimm slot = 625mhz 5-5-5-15 3-30-3-3-8 at 2.4v memtest able
Yellow dimm slot = 590mhz 5-5-5-18 10-42-10-10-11 at 2.45v semi stable in memtest

Huge difference!

More tests to confirm that indeed black dimm slots on Asus P5K Deluxe seem to clock these 10000C5D Dominators alot higher with tighter timings and lower vdimm than yellow dimm slots.

System

• Q6600 QUPT B3 ES
• Corsair Nautilus 500 3/8" ID
• Asus P5K Deluxe 0311 official bios
• 128MB Gainward FX5200 PCI
• 2x1GB Corsair Twin2X2048-10000C5D in black dimm slots
• 74GB WD Raptor 8MB on SATA 2 port
• Pioneer DVR-08 Burner
• Sony FDD
• 1KW PCP&C SLI psu
• WinXP Pro SP2

Corsair 10000C5D Dominators:

Using memtest86+ v1.70:

Yellow slots = 590mhz 5-5-5-18 10-42-10-10-11 at 2.45v memtest semi stable
Black slots = 625mhz 5-5-5-15 3-30-3-3-8 at 2.4v memtest able

In windows had to loosen the subtimings up and drop the clocks a bit for 2.4v vdimm but still @620Mhz 5-5-5-15 8-30-8-8-8 at 2.4v is much better than Yellow slots @590mhz 5-5-5-18 10-42-10-10-11 at 2.45v which was only semi stable in memtest.

Great George

We all know what your E6600 will do

Now what about FSB and how'd them Supertalents go ?

moloko

That CPU Voltage Damper option sounds like a great addition for this board

I'm with Graham, let the FSB fly and the supertalent's stretch their legs also

I'll be watching this with a keen eye as I hope to make this my next board.

maybe he's having a nap ??!!

Sleep is for the weak

Updated 5th post with some more benchmarks Asus P5K Deluxe - Intel P35 Bearlake + Intel E6600 B1 ES / Q6600 Kentsfield / X6800

Alot more tests to come

moloko

Thanks Eva, consider the information devoured

Please sir, may I have some more?

Jammer

Thoughts so far eva? how does this chipset compare to 965 or maybe even 975? From what I can see, it looks to perform slightly better than 965.
