32m Low Clock Challenge

[eva2000]

Finally broke sub 12min at <4000Mhz !

11m 59.656s @3996.7Mhz = 2864259.04 efficency

Used Maxmem = 615 with my custom fresh WinXP Pro SP2 nLite install

Finally I think it's time for you to move to DDR3......

not much use right now when my DDR3 Blitz Extreme is limited to 485-493FSB for cpus that can do 530FSB on Blitz Formula/Commando hehe

DDR3 needs high FSB capable cpus to really shine!

i thought i had my 32M SPi OS down to be as good as anyone but clearly i have a good couple seconds worth of work to do. time to start from scratch and try to find those last couple of seconds. my hats off to BA and gandalfone. all three of us with the same setups pretty much but they are clearly better than me at this point

Just when I caught up to your previous 12m 53.9xx run lol

System:

• Intel Core 2 Duo E6600 L709A958
• Corsair Nautilus 500 H20
• Asus P5K3 Deluxe 0604 official bios
• 128MB Gainward FX5200 PCI
• 2x1GB Crucial Ballistix PC3-12800 DDR3-1600 8-8-8-20 at 1.8v rated dual channel kit
• 74GB WD Raptor 8MB
• LiteOn 165H DVD Burner
• Sony FDD

• WinXP Pro SP2 Luna Royale Blue themed with nLite + RyanVM updates

7x514FSB 3:5 856Mhz 7-6-5-15 1T at 2.00v bios set
I finally broke the sub 13min Super Pi 32M barrier at <3600Mhz and when I mean broke, I mean I slashed 8.25 seconds of my previous personal time of 13min 02.094s!

I needed 2.0v vdimm as 1.95v vdimm resulted in memtest86+ v1.70 errors (4 errors at test #5 looping).

How's 12m 53.844s for 32M with WinXP Pro SP2 fully updated with no maxmem tweaks at all!





Now I wonder if I can go sub 12m 50s for 32M at <3600Mhz ?

[eva2000]

For now set RAS to CAS Write delay in memset from 6 to 3 and squeezed out 0.906 seconds faster 32M time

You see!.....I told you to go to DDR3.....

now do it properly and go for 509*7 under 13m...you should be mighty close if not already there. i expect an update in 12min 59sec

yeah DDR3 helped for sure

something to aim for I guess

[dinos22]

nice work george

[3oh6]

dusted off the phase this afternoon and went straight for the sub 11min category. there is still plenty of time left to shave off with this setup. i couldn't get 550*8 to run with the 3:5 ratio (200 strap) for 913MHz so i had to settle for the 5:8 (333 strap) and 875MHz. on top of that...my P5K3-Dlx won't be running 550FSB PL7 until it receives some 'help' so PL8 would have to do for now. be sure that i will be back in this category after some mods at PL7

I did vmch mod, maybe it will help for higher Mhz with PL7 ,but not

Great job

[dinos22]

was just studying Gautam's runs and it is very interesting to see how big the CPU MHz gaps start to emerge as you push into categories past sub 13m



we are talking about ~550-580MHz difference for 9.xx category and probably 650Mhz for 8.xx category wow


it would be so nice if someone smarter or less lazy than me could figure out the efficiency formula that has no bias so we can compare relative performance on any clock

[dinos22]

improved my 12.xx time a little






i am VERY CLOSE to a nice 9.xx category entry (CPU FSB is preventing me from clocking higher so i will have to tweak out those last few seconds )

[eva2000]

Good stuff dinos

my fastest sub 12min time to date @3959.9Mhz

[dinos22]

nice going there george

i will give you a run for your money on Gigabyte with 650+ on RAM for 11.xx category

Yep, since its inverse proportional, you'll always need more and more MHz for the same absolute time difference. I don't think there's any way to have such a formula. We can compare efficiencies at a given set multiplier/ratio/timings, but once those variables are changed, the efficiency will as well. When I was doing those runs I usually eyeballed efficiencies at the next multiplier step by adding the difference in performance product between the previous two, but that turns out to be too optimistic and is better for nothing but a rough rough estimate.

You guys are all making me damned jealous, nice to see all this action going on. Love seeing 3ho6 right at the 59.984 mark for 12.xx--that's the sign of a totally squeezed setup. I wish I had the time to do 32m runs on P35, you'd crap if you saw the kind of mem speeds I was seeing. DDR3 is def where its at now tho...keep defending DDR2's honor nonetheless dinos.

hello, i'm newbie here..this is my result

Hey Gautam,

Give us a taste of what rediculous memspeeds you're looking at atm, please?

[before]

Here's my humble contribution for the 9.xx club. Did it this afternoon while testing the cascade. Guess it could be faster; but it's not a too bad one actually.

[Gautam]

Hey Gautam,

Give us a taste of what rediculous memspeeds you're looking at atm, please?

Was looking at is appropriate...all I have saved from about a month ago is this. :-/ Bear in mind that 05 is quite a bit harder to pass than 32M, I was around 675 5-5-4 and 660 give or take 5-4-4 but both of them were lacking in perf so I didn't bother with them and didn't take screenies...now that I think about it it would've looked nice. 1M was around 700 5-5-5 in dual channel. Of course voltage was about 2.8v for everything. Right now I have nothing but a couple of sets of ram, a video card, a hard drive and a psu. No CPU or mobo.

Very nice my friend, seems like 5075MHz or so could've done the job.

[dinos22]

determined here to open up a 8.xx category

fingers crossed if everything works out to plan on Atomic Live our team will have a nice little time for some droolage action....my E6700 can do the clocks we need : , got plenty of capable mobos and RAM so just luck necessary now

more to come soon fellas

[Zeus]

What do you reckon it takes on your E6700? At least 5.5GHz i'd say with 600 on the rams or am i wrong?
