Are you all using ES chips or is the multi unlocked on retail processors too?

Great i was hoping for this, if I set my fsb at 7x433 what will i need to put my ram at?

Its Gskill NR 6400 at the mo im at fsb 333 x9 (3ghz) on my E6600 and ram is @ 833.

mmm i am not shure better perfomance, but my p5wdh is coming monday. :D

it's downward locked on retail and ES just using crystalmarkcpuid to drop multiplier for me as i am on 1101 bios and haven't tried 1402 yet

you can can't go higher on fsb try loosening trfc, trd, and other memset timings.. if you can gain a few fsb by loosening them, then your memory is partially holding back your fsb.. try increasing vMCH and vdimm as well

mines retail, tried all voltages on max and still cant ge over 421, at least its a start... hopefully asus will have a working almost perfect bios by christmas!

ok this bios allows multi but in strange ways couldn't boot over 390 fsb whatever ram settings ( spd or manual )

does anyone get the same issues ?

:confused:

if i try anything over 421 the bios post looks all strange, anything over 423 and i get my video card bios is corrupt, that is with the pci-express on auto or locked at 100, or locked all the way up to 110, no differnce, tried the 7x multi thinking i could go higher than 420 with that, but still the same thing, anything over 421 and the bios is all screwy, seems they might still have some bugs in this bios version. also running the fsb at 420, my rams at 840, trying to use a divider to get 1050, makes the computer not boot, i dont think its the ram i relaxed the timings and every cranked the voltage and still no post, but now i get when it posted and it didnt do this the first few times, cpu ucode error... whats that mean.. anyone else able to get over 421??:confused:

Well, If I'm correct based on this thread, http://www.xtremesystems.org/forums/...d.php?t=114998 you lowered your multiplier and raised your FSB to 421, you are stressing your chipset more than you think.

9/8 x 421 = 473.6 mhz or 1894.5 mhz on your chipset clock.

hence more vMCH needed :)

no probs on my P5W DH with E6700

@9x460fsb = 10/9 x 460 = 511.11mhz on chipset
@8x450fsb tested so far = 10/8 x 450 = 562.5mhz on chipset

vMCH = 1.85v water cooled

more vdimm helped me tighten the memset timings otherwise i need to loosen tRFC from 35 to 42 for >452fsb.

it has to do with 975 tmings.

i dont bealive 975 can go much more than +- 420 FSB unless you guys could have access to that timings .

Is that a geniune retail board though eva2000? I don't know what to believe on these forums anymore.

Paid £200 for a P5W64 that arrived today on the strength of stuff I've read on here and it doesn't go over 420FSB 1:1 (6x420) regardless of vMCH. And this is on a CPU that I know does 3.6Ghz dual Prime stable, and memory that does 500Mhz (G.Skill PC2-6400 2GB HZ).

And you base this on what?

thats more than proved that 965 have more relaxed times than 975 and thats the main reason they can run much more FSB but the results are also worse , like in Superpi ate same CPU Speed you have less +- 1 second with a 975 than with 965 .

and it looks like the new revision of 965 (C2) have even more relaxed times than the actual revision 965 (c1) cause can run even more FSB but the results are even worse than the 965 (c1)

well it is from Asus direct but it's straight off the production line ... on stock out of the box it won't do >440-445fsb without loosening memset timings - once loosened 450fsb was fine and 1M pi 473fsb was fine on E6600 ...

Water cooled MCH helped, pencil mod vdimm increase from 2.4v vdimm max to 2.51-2.54v vdimm helped, phase change cooling helped...

Biggest change i think was vMCH cooling/voltage and increased vdimm available.

vMCH cooling/voltage = help increase max fsb and help increase max mem clocks

vdimm increase = help allow memory to handle tighter memset timings thus higher fsb max - you can confirm this by trying to run downclock mem divider 4:3 etc and see if max fsb improves - if it does, chances are more vMCH/vdimm volts will help increase max fsb.

I remounted the stock passive heatpipe on P5W DH when i first got it several times, each time got a different max fsb with a variance of 5-11fsb! Worst mount limited me to 432fsb max hehe

Right contact on MCH/NB core helps too!

thats the reasons you are the only one getting more than 420 FSB .

i bet a regular 975 Mobo with NO MODS can get Highs FSB cause the reason i already said --- chip7 timings that we dont have access

So, currently I'm @ 400x9 1:1.
Is it even possible for my OCZ Plat 6400 REV. 2 to do 450x8 1:1?
Am I high

I didn`t see a p5w doing 7 x 535 on air ( http://valid.x86-secret.com/show_oc.php?id=120669 ) , I think the p5b Deluxe get`s the hot board crown.... :D

I've booted into windows @ 9x423FSB. 1:1 4-4-4-8

I guess it's time to break out the soldering iron and NB WaterBlock....LOL 500FSB here I come!! LOL :toast: :banana:

Edit: I do have a fan blowing on the NB, maybe that helped get over the 420 FSB wall???? I don't know.

Sorry, this is the same old garble that's been posted here for weeks. A little less speculation and a little more fact is in order... Now if we let people that actually own the 975 product test the theory now that they have downward multipliers rather than have 965 owners who don't have clue continue to speculate, we might finally have an anwser... :)

Thanks for that. :)

One thing I can't understand at all...

I've seen people on here talking about getting 470FSB "no mods". I'm assuming they mean they haven't touched anything. Then I read the Hexus review of the P5W64 where they say they got 500FSB just by changing vMCH to 1.7.

I get my P5W64 today, hook it all up - haven't touched a thing except change voltages in the BIOS (all the obvious things like HyperPath 3, etc disabled) and I cant Clockgen over 410 reliably whether my memory is SPD or manual, or my vMCH is Auto or 1.8v.

I'm seriously missing something I guess.... does the board change the strap after 400FSB?

im not speculat nothing , are facts .

why do you think new revison C2 965 can run 600 FSB???? >>> i bet its because have even more relaxed times than the previous revison 965 C1 , but for example results in super pi 965 C2 its even worse than 965 C1 ;)

if you think this is only BS and teory keep with your teory ;)

Now that ppl can try low multis lets see if im wrong or not ( im not saying i am right ) .

you can count with 3 or 4 fingers of one hand the ppl who can run more than +- 420 FSB in regular 975 mobos with NO MODS and most of them with ES chips .

at least i have a " theory" for that, let us hear yours , its also wellcome .

???????????????????????????????

what the heck that post have to do with my theory about ppl cant get over 420 FSB with P5WDH ?????

ok you dont have a theory , thnks i already knew it

and if you read the thread i never get OFF topic , are you sure your feeling OK???

whatever , keep the bicycle .

guys if you can find a way to beat the 420 FSB wall post it , we apreciate

On my P5W without Vmch V-mod at 1.65V is maximal frequency 419MHz. After V-Mod and Vmch 1.75V is my max stable FSB 440MHz. For better FSB frequency than 420MHz you need raise Vmch voltage.

I just realised how pointless it is for me to have this in bios LOL..

I'd much prefer to be able to set tRFC and tRD in the bios, that's what I REALLY want asus to implement..
