has any1 tested this yet

[bachus_anonym]

Thanks Andre :up: :toast:

I flashed it 10 mins ago. Running SPi32M @ 400x9 4:5 as we speak. Next I will do 450x8 4:5 and post results afterwards.

[Supertim0r]

thanks a lot Andre :toast:

[aggybong]

Is this official or still a beta?

[AndreYang]

Is this official or still a beta?


It's beta.

[thelostrican]

how about temps is it better now than before?

[pcdoc1]

thanks alot Andre :clap: :clap:

[metro.cl]

tomorrow i'll have this mobo shipped :)

hope it ocs well

[shine121]

thanks, will try later

[Supertim0r]

also priming @ 400x9 DDR2 @ 1000
was impossible before
:banana:

[ScottFern]

Is 4:5 a better (faster) memory divider than 1:1 ???

[Kashath]

Yeah

[Raz2133]

how about temps is it better now than before?
I noticed that since BIOS 0607 (maybe 0605?), the temps reported by the Asus Utility are a lot closer to those reported by Coretemp and the Intel Thermal Analysis Tool.

OK, so check this out...

I'm on stock heatsink at this moment and my CPU maxes out at 3.60GHz, 32M stable. So, I first run SPi32M @ 400x9=3600MHz, DDR2-1000 (667MHz ratio, 4:5) and got 13:42.797 (http://www.clockmehigh.com/cooler/screens/965P/0609BIOStesting/400x8=3600MHz_667ratio_32M.png).
Above result is about right, since at 400x9=3600MHz, DDR2-1200 (800Mhz ratio, 2:3) and same conditions I get 13:15.437 (http://www.clockmehigh.com/cooler/screens/965P/6400C3/400x9_DDR2-1200_32M.png).

Then I dropped multi to x8 and it appeared to boot at max 440x8. As it was not very stable, I lowered FSB to 432x8=3456MHz, DDR2-1080 (667Mhz ratio, 4:5) and got 14:40.641 (http://www.clockmehigh.com/cooler/screens/965P/0609BIOStesting/432x8=3456MHz_667ratio_32M.png). Whoa, that's quite drasatic 58s loss! That's at lower CPU clocks, OK, but higher memory frequency (at least, according to CPU-Z). There would be drop, but this is a big one!

Now, this was for a comparison. I upped mulitplier back to x9 and decided to do one more 32M run at the same CPU clocks as above, therefore lower memory clocks. So, I'm at 384x9=3456MHz, DDR2-960 (667MHz ratio, 4:5) and got 14:11.250 (http://www.clockmehigh.com/cooler/screens/965P/0609BIOStesting/384x9=3456MHz_667ratio_32M.png), wth :confused: :confused:

So, now the only thing that came to mind was to run 432x8=3456MHz, DDR2-864 (533MHz ratio, 1:1), which got me 15:11.266 (http://www.clockmehigh.com/cooler/screens/965P/0609BIOStesting/432x8=3456MHz_533ratio_32M.png).

I repeated 432x8 run again and got the same result as the first time... Some more testing must be done, but it appears to me that perhaps past 400MHz and ratio 667Mhz selected from BIOS, performance really goes down the drain :( Would that be possible that internal chipset latency gets altered at this point, causing such a drop in performance?

Maybe past 400 Mhz the bios select the 1333 chipset strap and gives you an effective ratio of 5/6.

[dinos22]

Bachus check memtest bandwidth between the two

if you see a big drop you'll beed to investigate timings (i've noticed Gigabyte DS3 do that)

[Raz2133]

Unfortunately, this BIOS makes my previous dual Super-PI stable 3.4Ghz overclock (E6400 @ 8x425) totally unstable, it errors out within a minute or so.

I can't even get it stable at my previous 24/7 speed of 3Ghz (8x375). :(

I have a feeling that the new timings in this BIOS are messing with my crappy Samsung RAM. Arh well, I guess I will fall back to a previous BIOS, at least until I have some better RAM to try.

I think it confirms loss of memory bandwidth at 667MHz ratio and past 400MHz :(

this bios also alows me 400x8 with 4:5 priming 1 hour now will let it go over night.

ram auto'd at 5-4-4-12 2.25vdimm nice ddr2 1000 :)

ran into some issues with this bios, flashing back to 0507, poor performance as well.

yeap it has to be something to do with >400 FSB

just manually set ALL the RAM timings if you haven't already

maybe they are forcing 1333 strap somehow past XXXMHz fsb

you able to do some 6xmulti tests with different FSBs

[mackanz]

Then the difference should be very visible between 9X399 and 9X400. Do a comparison with SPD enabled to take everything out of the equation. Theoretically, the difference shouldn't hardly be anything in either superpi or latency tests, but sandra might show a huge difference (as usual :rolleyes: )

For now, I flashed back to 0507 becasue I have another OCing Report to finish up first. But I will come back to 0609 in a few days :)

I'm actually now trying to remember If I haven't by any chance seen something similar on 0507 (and I guess earlier BIOSes) when using DDR2-800 ratio. I remember I run 16M @ 400x9 @ 2:3. Then I booted to 404x9 @ 2:3 and time was very noticeably slower than at 400x9... I was very surprised. I'll try to replicate that and post later.

[ent]

So this performance drop happens only with 0609?

[yotomeczek]

As Bachus wrote - with 507
"404x9 @ 2:3 and time was very noticeably slower than at 400x9"
so ... it is propably 1333 strap :( - or mobo set 4/5 div instead 2/3 ... don't know
It's Wired :confused:

[sierra_bound]

Andre, have you tried this bios with Kentsfield? Multipliers up to 12 are available, but when I set it to 11 or 12, it ends up going back to 10.

Unfortunately, FSB is not as good with Kentsfield as some of the earlier bios versions.

Has anyone asked an Asus engineer about NB straps? Maybe they are using just one strap to cover all frequencies. If they were using several straps, why wouldn't they just make it available as bios option like on the Bad Axe? By the way, a 1333 strap would kick in much earlier than 400MHz. I think there is more to this than meets the eye. Also, I think some people are confusing the NB strap and the memory strap. They are not the same thing.

[Pt1t]

Boot @ 400*9

http://users.skynet.be/pt1t/P5BDLX/400X9_4-5.PNG

Boot @ 425*9

http://users.skynet.be/pt1t/P5BDLX/425X9_4-5.PNG

Boot @ 432*9

http://users.skynet.be/pt1t/P5BDLX/432X9_4-5.PNG

Boot @ 425*9 and Downclock to 400 with clockgen.

http://users.skynet.be/pt1t/P5BDLX/400X9_4-5_after_425_boot.PNG

And if i boot to 400*9 and clock to fsb 425mhz, --> Reboot ^^

[dinos22]

i smell a rat

i was wondering why my times were slower with 7* multi on E6300 on P5B Deluxe compared to 8* multi and slower RAM on E6400 on DS3.........well i'm yet to fully tweak the RAM and OS but from initial 32M runs it looks a bit :banana::banana::banana::banana: hmmmmmm

[Krimi 2000]

I have same problem. Bios 0507.
8x450Mhz is slower than 9x400 with same timing.
Everything set manualy in bios.

Is it fixed in 0609?

check my result .... with Bios 0609

[GAR]

its wierd how my memory bandwidth is faster with 400x9 then 425x9.......both with 1:1 mem divider...seems like my sweet spot is 400x9.

[Gambit_2K]

Anybody tried the 0605 bios and checked if it really has the multi that is lower then 1:1, or tested the 0607 bios?

what sort of fsb have you managed to get with the kentsfield with this bios?

thanks

there is no such thing as RAM divider below 1:1 on 965 and will never happen so don't even bother trying to find a bios for it

i use 0607 it's good :)

here is a partial answer..no mention of bios but FSB....

I didn't test 11+ Multipliers, but I test FSB limit is the same other BIOS.

ASUS always cannot promise any overclock FSB higer. They just promise default CPU speed stable. So I only ask ASUS engineer to get me beta BIOS for overclock. Maybe Official BIOS is not good oc to use.



Kentsfield is no problems.

I decided to give 0609 a try today, but I ran into problems with random system freezes, so I reverted back to 0507.

My BIOS flashing history: 0302 -> 0405 -> 0507 -> 0502 -> 0609 -> 0507

[dinos22]

Andre that is one impressive OC on that motherboard :toast:

[Revv23]

just bumped into this thread, subscribed for when i get my p5b on monday

[Absolute_0]

Seems that as FSB increases, so does the Strap, and as speculated this might might kick up to a 1600 Mhz strap, so i'm assuming the 1333 is going to kick in quite early.

High FSB at the price of a high strap and diminished performance.

[sierra_bound]

Performance is somewhat diminished. But if you're running 500+ FSB @ 1:1, the RAM speed helps make up for that. Also, it's fun to run at 525+ FSB every now and then. And the P5B Dlx is the best board for doing that.:)

[astaris]

there is no such thing as RAM divider below 1:1 on 965 and will never happen so don't even bother trying to find a bios for it

i use 0607 it's good :)
I think that with the 1333 strap the 5/4 divider (FSB/RAM) should be available, we'll see.

[pcdoc1]

High FSB at the price of a high strap and diminished performance.Seems like the question is if the high strap is offest by the higher fsb...

[Revv23]

i think bachus's poor performance at 8x is because of the nbcc going higher when at lower then stock multiplier's, as pointed out in tony's thread, whenrunning lower then default the strap changes with your NBCC and not your fsb, which would make the strap change much earlier on lower multi. Perhaps that will explain why 8x440 is so much slower then 9x400.

Damn :( I ordered this board yesterday and I got exactly the OCZ2G8002GK-6400 kit.. So i won't be able to boot with them? That's the only DDR2 sticks i got :(
