Maybe bios related?
this is the same as F3 biosQuote:

but i guess it could be bios related for Wolfdales donno
This thing really is bios related, can't go past that. There are only three (DDR2) motherboard/bios combinations I have seen hit 45k or even sub 45k and those are:
Gigabyte X38-DQ6 - Bios: F2
Asus Maximus Formula SE - Bios: 0401
Asus P5K-E - Bios: 0503
Just checked cpu compatibility of those bioses: none of these bioses support 45nm chips as support has been added in later revisions.
You can add P5E3 WS with 0124 Bios. Hipro was this your BIOS during spi benches ? Me yes (7,891s @ 5733Mhz)Quote:

There seems to be a difference between DDR2 and DDR3 motherboards, though.
Massman they don't need an update because they already support them
Not officially :).
Those three DDR2 boards give awesome 1M performance with biosses before the micro-code update of the 45nm cpu's. With other biosses it seems to be less performant (or I haven't payed attention to it, which could very well be)
gigabyte does not have a single decent bios aside from first release for both DDR2 and DDR3 boards :( (as in poor FSB performance and very buggy RAM dividers)
i can do similar efficiency with DDR3 GB board too so you can add that to the list lol
and i used two bioses this F2 0115 and F3 on DDR2 board
btw massman F2 0155 bios is basically F3 bios with yorkfield/wolfdale support massman ;)
same efficiency
with F6j bios 32M SuperPi is quicker with QX9650 :S

Its bios related, not supporting bios is fast @1m and slow @32m so newer bios give you better performance on 32m .
@massman
Blitz extreme ddr3 has the same issue....45k on DDR3 :)

BTW We are looking for dumps done with other motherboards than the P5E3 WS Pro which is the one we actually use. Making comparison with several different boards can help saving so much time.
If you're using Gigabyte X38-DQ6 - Bios: F2; Asus Maximus Formula SE - Bios: 0401; Asus P5K-E - Bios: 0503; or any other one with which the phenomenon occurs... Could you please save CPU-Z registers dumps (.txt) and then send them to me? What we need are 2 dumps, (1) with pre-45nm bios and (2) with post-45nm bios; both done under the same conditions (I mean the same bios settings).
If you wanna help but still have some questions, please feel free the ask me in pm... :up:
i'll help out next time i bench
i will also use X38T-DQ6 (DDR3 board) early bios to see it does the same
Same here with Blitz Extreme :) I was also going to investigate mchbar registers, could be on of the reasons
Thanks guys :toast: Any help will be greatly appreciated! :up:

You need to shave of 0.145 before :D
dumps coming up,have new cpu and try te get you dumps of maximus formula/blitz extreme/striker II formula
Yeah; thx for your help!
An hardware tweak is needed :) Actually, it looks quite improbable to get sub-45k @ nearly 5.7GHz.
Nobody wants to help? :(
What you guys can get in term of lowest pp with a post-45nm post? Any sub-46k out there?
so far my lowest was around 46.2
Mine was 45900pp; dunno if that's because I've started to play with the right MCHBAR offset, or if that's thx to a well tweaked OS.
45900 with which multi and clock?Quote:

hmmm hard to tell, you are on the edge, I can go 460xx, maybe even 46 flat with DFI, but not under it, and can make 449xx with 45k BIOS with Asus on 600fsb 1:1 ddr2. What does runs say if u just playing with mchbar? (leave some win setting and tweaks and just play with mchbar, any different scores?)Quote:

When I was doing 32M low clock @ 8x500 833 6-5-5 I also did quick 1M (time 11.500) and it was flat 46K or slightly less because cpuz read 3 values - 3999.9, 4000.0 and 4000.1.
Yeah; but 500FSB is very helpful. Anyway; I can't test it more because my cooler master PSU have just died killing my VGA + P5E3 WS Pro... :mad:Quote:
