SuperPi32m 5Ghz Ivy All Out Challenge!

Looks like Intel shifted the POST calculation to include WCL from SNB onwards. Previously these two were tied on X58 and P55. IO-L is buffer latency and allows RTL to be shifted to account for any IO delays from the DRAM buffers (there is also a clock skew offset but that value is internal and calculated during POST).


EDIT: I should add that IO-L is an offset, the base value it is added to shifts so adjustment does not always help. The shifting in the base value is due to read/write levelling drift. This manifests at speeds higher than DDR3-2000 depending upon the DIMMs used (some DIMMs are okay to DDR3-2400). Basically you have to get lucky with training for stability.


The effective RTL time is likely close to: 8 X ((1000/Uncore Freq)+ Clock skew)+tCL. The IOL likely moves a pointer at the IMC FIFO buffer for data arrival on top of the RTL time. Uncore freq should be around DRAM Freq on this platform. I had a quick look at SNB last year and it seemed that is what Intel had done, I would assume it is the same here.

Thanks for the explanation Raja hope i'll be lucky again.
Manually changing the RTL & IOL on that rank in Memtweaker (must apply both at same time) hasn't worked very well so far.

Think this about all I got!

fine looking run there C-N .. there is usually something more need to find some of it myself heheh


@trans am
have you disabled 'No Execute' memory protection or whatever it's called on your board ?
Execute Disable Bit on Asus, can't remember for GB.

SSD here as well - an old Intel X-25V.

Any ideas why I can pass 32m but cdt/copy waza gives me bsod lol?

Thanks buddy I was told many times to ditch server 2003 & run XP & for me getting my lazy a** fired up enough to make a skinny XP has made a great improvement.

yes i believe when I was on the asus execute disable bit was default disabled.

I havent done any specific ssd tweaks for this xp install. I googled xp ssd tweaks and found this ocz thread. Are any of you guys using any of the suggested tweaks on ssds?

btw nice run there C-N. I wish I could get this ironed out so I can play. just gimme anything under 6:28 and i'll be happy.

i disabled execute disble bit on the the ud3h. still no gains.
ocnub. I had the waza problem too. I could run 32m but when I ran ocx I would bsod. U need to reinstall os and start from scratch. that was the only way I fixed it.

if I only have 2 dimms populated should I shut bank interleave off?


******EDIT

you nailed it execute disable bit was enabled. I disabled it and i'm doing better. hang on.

[Splave]

what are you using for waza settings and max mem?

[trans am]

what are you using for waza settings and max mem?

670 maxmem
and im using ocx just until i can see some changes. i will do manual waza down the line but i just want to see some quick tests.
ocx is 800
spi drive x
os c
32kb
35s sec
cdt

ran a few 16kb then fussed around 93 jsut guessing. then hit 32m and enter run ocx
then hit pi right after ocx counts down

[trans am]

ooh 6.27

getting better
something good is actually happening.

[gungstar]

using ssd too

[M.Beier]

A little more improvements, 6m 24.xxx, still not satisfying.... But will have to lay it off for now, will try a bit more hw next weekend, have to hit below the 20 barrier, else a kitten will die...

Any ideas why I can pass 32m but cdt/copy waza gives me bsod lol?

Memory is unstable. You might get away with lowering the CPU multiplier during Waza if ROG Connect allows.

Hi all, trying to learning the ropes (again somehow)... No wazaa.

^tRRSR to 4 will give you a healthy boost

[maxxx]

Thanks Splave. Gonna give that try.

I haven't looked here for some time and i can see that there are some many good scores !!

Raja you're a top memory tweaker !

My Asus gene V is dead , so i can't continue . I also lost some screenshots with 6.19.X i had with 2 PSC sticks . I accidentaly deleted them ...

My only option is to wait till next month for the formula V or extreme V.

it does that cauz mem its not stable, if you shoot memtest im sure will fail (memtest win)

True
I find it is way faster to see if 200%-300% coverage passes memtest then it will pass 32m

yes and for a quick revision instead of waiting memtest hyperpi32 will tell you instant

this i just achieved and very happy for my daily setup, will shoot a SPI32 im sure it will drop a bit my score

Just an update on my run. Thanks to Splave's tip plus a little wazaa and bit more memory adjustment (not to mention more voltage).

I kind of figured, but I re-installed windows and had no problem passing 32m with the same settings, so thought it may be something else.
