Not bad for an old Q6600 B3 ES that couldn't get more than 400-425FSB on Asus P5B Deluxe, limited at 350FSB on Asus 680i Striker, limited at 345FSB on Intel D975X Bad Axe 1, and 350FSB on DFI ICFX3200 at 9x and 400FSB at 7x or 8x.

so I guess I should rip out the supertalents and drop in the Crucial Ballistix 8500.......??
hahaha.....when will this madness ever end

Easy solution ripout all your memory and shove them in MY rigs That should end your madness

Re: Asus P5K Deluxe - Intel P35 Bearlake + Intel E6600 B1 ES / Q6600 Kentsfield / X68

Thanks to Asus P5K Deluxe, my Q6600 B3 ES is in the running for this 32M low clock challenge...







I can't wait to pluck in my X6800 B2, knowing that core 2 duo B2 stepping cpus are clock for clock faster than B3 quad core cpus in Super Pi

Pushing Gautam down the ranks was very close @3311Mhz only needed 0.423s faster time hehe

The Stilt has figured out the strap changes for P5K Deluxe/P35 chipsets http://www.xtremesystems.org/forums/...9&postcount=17

By The Stilt View Post
On Asus P5K-series there are two strap changes:

At 293FSB the board changes FSEL strap to 1333FSB to make more memory dividers available. This doesnīt have any effect to performance.

The performance level is also changed for following dividers:

1:2 Performance level changes from level 2 to level 1
Level 1 is the tightest possible, so expect some huge bandwidth

Dividers 3:5 & 1:2 are FSEL strapped to 800FSB.

At 500FSB the performance level of all dividers are set more loose.

1:1 Performance level changes from level 6 to level 10.
Level 10 is the loosest one. Usually the chipset can handle level 5 just fine

5:6 Performance level changes from level 5 to level 8.
Setting level 4 should not be a problem.

4:5 Performance level changes from level 4 to level 7.
Setting level 4 - 3 should be fine.

Since the memory frequency would get a bit high at bigger dividers I donīt have actual values for them. But I recon the values would be following:

2:3 Level 3 -> Level 6
5:8 Level 4 -> Level 7
3:5 Level 2 -> Level 5
1:2 Level 1 -> Level 4

Re: Asus P5K Deluxe - Intel P35 Bearlake + Intel E6600 B1 ES / Q6600 Kentsfield / X68

Anyway tried 2x1GB Team 6400C3 D9GMH + 2x1GB G.Skill 6400PHU2 HZ D9GMH @490mhz 4-4-4-9 2-25-2-2-4 on P5K Deluxe to compare with 2x1GB OCZ PC2-9200 FlexXLC @490mhz 4-4-4-9 2-25-2-2-2 on same board (FlexXLC handles tight tRTP like a champ!).

Probably not as huge a difference due to tightness of the subtimings ?

Re: Asus P5K Deluxe - Intel P35 Bearlake + Intel E6600 B1 ES / Q6600 Kentsfield / X68

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
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

CPUZ Validation


Super Pi 1M


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!

By bingo13 View Post
The black slots are required for high memory clocks or stable low latency settings on either P5K board, in fact on the P5K3, the only way to get above 1800 in dual channel mode is to use the black slots. ASUS has the official explanation coming shortly...
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!
