SuperPi32m 5Ghz Ivy All Out Challenge!

[andressergio]

Hi AS, should be running 32M

crap lol

[Splave]

only managed to run 2400 6-10-7-24 with psc chip wont do .1 over 2400mhz on the mems imc is weak. now board is dead lol woops

[C-N]

Sergio this is the 5GHz 32M challenge mate....... tweak for 5G 32M & your in

Sheesh and i thought the IMC on this one was so-so...

dino,

those rams arent there for 5ghz fun, stop beating me with my own sticks!!!

get those suckas cold! i wanna see how they react. 2600 c8 air isnt too shabby, and you know you have 50mhz headroom on air

[Splave]

Sheesh and i thought the IMC on this one was so-so...

its in the dishwasher right now, took 2 cans of automotive electronics cleaner to get most of the DOW corning 4 off...stuff is stubborn as hell

I'll attach the jumper cables to revive it like the Frankenstein monster

[cheapseats]

(EDIT: not for update Honda, thanks )

got up to 1276mhz but it only cut 0.14s from 1250mhz run. That includes using Spi Booster on 0086.


cheapseats - 6:19:640 - 47x106.4 - 1276.5MHz - 9-12-8-30-86-1 - ASUS MVG - Exceleram EB3103A 4x2GB/PSC - 1.85V - air

4x2GB




Memtweaker Timing#2

CHB DIMM 0 is tricky .. will only run with different RTL & IOL for ranks 0 & 1.
Sometimes boots with both ranks at 41 & 4 but fails at Loop 6. Only passes 32M if Rank 0 is 40 & 3




----------------------------

awesome run raja!

CL6 with WCL8 is bad combo :P

try CL6 and (if your ram can do it), WCL6 or CL7-WCL7 etc.
PSC dont like WCL > CL

correct, CL values where WCL > CL is wasting time with PSC/BBSE.

this table was for Sandy + PSC, but the CL + WCL combinations for RTL & vDIMM scaling also apply to Ivy with PSC

the Hyper table was just a reference to show the differences in RTL scaling with PSC CL.

here i go again

well im proud to join the club with my old MIVE P67B3 and my patriots 2000 9-11-9-27 1T
W7x64 SP1 no optimizations just classic desktop

yes sorry i just corrected

yay thanks !!! will keep pushing the MIVE

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.

I bet we will have campion 6min16sec soon.

No Saying, but Showing

[Raja@ASUS]

I think this one is more about knowing before showing

[C-N]

Think this about all I got!

[dinos22]

Well done CN, try more vdimm and higher clocks, looks nice

Thanks dino, more vdimm is not helping atm I can go faster but not quicker although I will keep at it.

[Splave]

DRAM-IMC offset on formula is game changer 9-11-9 2550mhz not working on my pi's (it wants 9-12-9) volts not helping fails @ first iteration
Bumped DRAM-IMC offset +.01165 now 32m stable...Im stunned, those asus boys know what they are doing

If I cannot break 6m20s on air with this board then I will quit 2d benching for good lol

[OC Nub]

^ I have 2 kits of pi's now that will do 2550 8-12-7, but for whatever reason my scores are better with the 2x4gb ripjaws at 2666 10-12-11

[Splave]

is it because high tWCL?

[OC Nub]

IDK lol, tWCL is 7, boots fine at 6 but pc shuts off doing waza.

Not sure why my times are so poor with 2x2gb kits. I started off going by cheapseats timings and subs, then went to 8-12-8, then 8-12-7-27.

[Dumo]

Dram-imc +/- in formula bios is awesome

Got another set of blue gskill 2133 c8 and an imc retarded 3770K, hope it will wake up with cold

[OC Nub]

^ LOL

My chip sucks on air/water, but on phase it does ok.

Its humid here this evening, but Im hoping later tonight Ill be able to play some more.

[trans am]

im going to assume everyone in here is using a raptor? Ive been on ssds. is there anyone on ssds? is this why my scores are so bad? ive been on 3 boards. 3 sets of ram, 2 cpus, differnent os, waza manual, waza with ocx. the only thing that hasnt changed is ive been on ssds the whole time.

[OC Nub]

^ Im on an Intel SSD, I think Dumo is also.
