thx to my great new Alu_pot, my x68 max suicide clk=5.2G, but 5.1G pi_32m benchable :D

Told you you`d manage it! I knew there`d be 625MHz on the RAM :p: :fact:
Congrats!! :toast:
Congrats :toast:
Sick speed. :slobber:
today is just for brief LN2 testing of my new x68 (1.65v 4G sp2004 on Air :eek: ).Quote:

I've tried 393*13=5109mhz, ram=1179 4445, but only 1sec faster than my 5Ghz, 9min55s, so I decided not to post that :p:
higher ram_clk is always preffered for 32m running as I told long time ago.
even 500mhz 3-3-3-8 is slower than 1200 4445 ;)
You have really nice CPU there, nice results ;)

wow Vic I got same batch cpu too

Thanks :D
which line is that # ? 2nd line ?
mine is #1746 - bought cpu new locally and got their last one in stock .... runs extremely cool at 3808mhz at 1.55v prime at 59-62C load and at 4092mhz at 1.65v idles at 43-45C and load no more than 62-65C!
why hard for 965 ? due to strap change at 400fsb for decent times ?
yup, mine 1.65v sp2004, watercooling, ambient=16c.Quote:

don't know why, but... 4.1G chip on 975x can only run about 4G on 965.
especially e67 , x68 and qx67.
maybe asus' 965 mobo needs GTL mod like master The Stilt done :D
Oh looks so good! Now I want to play with LN2 bad :D
yeah my ambients between 24-34C lolQuote:

Same as you all my E6600/E6700 B1 did 40-90mhz better on 975x than Asus P5B DX
Oh god! Victor, you've just taken my own aim... after getting the lowest clock ever to break 10s barrier @1M, I wished to achieve the lowest clock ever to break 10mins barrier @32M :D
Congrats! With such a hell of memory kit, you'll own this WR for ages... no doubt about that! :toast:
625MHz 32MB is very nice at 4-4-4-5!
I hope you got a fan on those RAMs though!
2.8v = :slapass:
great pi score vic , nice rams 2
hhhmmm btw switch from a 965chipset to a 680i will this gain some mhz 2 ?
hope so :D .
hopefull ul get great clocks with LNē on ure rest off cpu's
nice performance/clock..;)
Awesome result, especially for 965P :)
Great benching as always, big clocks are nice but to bench those speeds with efficiency is all the more impressive. :toast:
How do we calculate the clock for clock efficiency?
Is it (MHz) x (seconds) and the lower the result the better?
eg:- (taken from hwbot top 5)
1. OPB - 5504 x 578.810 = 3185770.24
2. oc_windforce - 5455 x 580.17 = 3164827.3
3. VictorWang - 5000 x 596.810 = 2984050
4. hipro5 - 5328 x 599.56 = 3194455.6
5. Memoryextreme Team - 5240 x 612.14 = 3207613.6
Shouldn't that be (seconds) / (MHz) ??Quote:

I know they were using (MHz) x (seconds) to see efficiency in 1m so would it be the same for 32m I don't see why not... but I'm no mathematician/statistician.:p:
No, MHz*seconds. Pi times and clock speeds do not follow a linear relation, rather an inverse one.Quote:

thx guys!
for this 5Ghz result,
I've done lots of Warming-up excersices :D
my Geil can run at lower volt. @ 1200mhz but... not good when > 1233mhz even if I flash Team's SPD to Geil...
so...maybe "Good Ram" needs to be re-defined : higher clk with good timing is preffered but not "lower volt".
I think it's same with "Good CPU", good on air not means good under cold.
here are some more reults for ur refference:
1. 3.75Ghz=12min30
http://www.xtremesystems.org/forums/...1&d=1170760953
2. 4.95Ghz=10min13sec
http://vic.expreview.com/attachment/1170757033_0.jpg
3. 5.1Ghz=9min55sec
http://vic.expreview.com/attachment/1170776747_2.jpg
so u guys can figure out how important RAM clk is to achieve such efficiency.
all timings I set in bios, no more tweak and no optimized OS.
maybe one day, break 9min50s with 5Ghz is prossible :p:
2:3 on 965 must be the fastest combo possible (except 2:3 on 975 if anyone can swing it at such clocks :p:)
Great times Victor, and you're absolutely correct in saying that good air CPU's aren't always good subzero CPU's, and memory that does well at low voltage doesn't always do so well at higher ones.
heheh funny you say that because people were claiming without proof of course that 4:5 ratio is the fastest :DQuote:

Great speed for that setup, keep it up :clap:
Many Japanese benchers used the 2:3 on i975X since the early Conroe days. Even with the memory in the mid-550 range, it's still extremely fast.
And if it were just Asus' fault, wouldn't we see more 4:5 clocking on other boards? ;)
is this win xp or 2003 ?
tks
More proof that 4:5 divider on P5B Deluxe is alot tighter wound than 2:3. Only ~2 seconds faster with 11x372FSB and 2:3 for 558mhz 4-4-4-4 memory clocks vs 10x409FSB 4:5 511mhz 4-4-4-4 mem clocks.Quote:

http://fileshosts.com/intel/Asus/P5B...2m18s172ms.png
4091.3 x 738.172s = 3,020,083.104
4092 x 736.282s = 3,012,865.944
To hit 558mhz on 4:5 divider you'd need 446FSB .. now stock P5B DX boot up at 446FSB would be slower due to strap change, and from what most users like Bachus and I have experienced stock max vMCH on P5B DX only allows clockgen from 400FSB to around 432-440FSB. So you'd need vMCH volt mod for 4:5 to hit 558mhz memory.
Congrats:p: 到XS 来日一下V.W :toast:
4:5 on p5b is really hard to run but sure it's faster perclk than 2:3 < 1200mhz.Quote:

it may be the case but the problem is that it just doesn't clock high enough to be able to be the real contender......my Hz sticks do 543Mhz 4-4-4-x 2.4v on 2:3 and sub 480MHz on 4:5.....even if 2:3 takes it out by a handful of seconds it's still faster overallQuote:
