After a week testing 32m on Ivy for LLC

This one is new on IB 32m benching.

 

Maxmem = Default Stable (10 runs)

Maxmem = 600 Failed (10 runs loop 1 to 5 )

Maxmem = 620 loop 15 memory Error (2 times passed all loops in 10 runs)

Maxmem = 640 100% stable (10 runs)

 

M4F and M5E with 3 different OS

G.SKILL 2600 Sams default 1.65 to 1.75 same error 23XX Passed

G.SKILL 2666CL11 Hynix Default 1.65 to 1.75 Same error 23XX passed

G.SKILL 2400 CL8 PSC Default 1.65 to 1.75 same error 25XX Passed

G.SKILL 2500 Cl9 PSC Default 1.65 to 1.75 Same error 25XX Passed

G.SKILL 2133 Cl8 BBSE Default 1.65 PASSED with no error , 2400 Failed

 

 

 

 

What about U?

 

Please test if u get Not exact in round error

 

Am i too OLD and found out this to late?

Tried on various mobo various OS?

I've experienced same, but different value.

Didnt bother noting it though.

Tried on only M5F and M5E here, but seems Dinos had the same problem with GBT.

 

EDIT : Dinos said : just kidding man lol. i just use 640 cause i just do, didnt see that before LOL

 

 

So guys try it if it's interesting, all we think it's mem fault.

Hmm, will link John Lam this thread, pretty sure he has tried across a few boards and OS'...

I was testing 32M for 5Ghz LCC with BBSE that is known to run 2600+ c8 and no matter what I was always getting not exact in round every time with maxmem set to 620, I usually use 670-680 but for testing purposes I figured I should try a few different values.

 

I will retry with 640 and see if this changes anything.

i generally just use 640, no i didnt actually see any difference in any value but will try push ram to the edge and see if i can replicate that

I didn't see a difference with different values as well and I usually use 640.

YES,i found that too.I get that error dozen of times,sometimes out of reason.Now i test at 640 and it's huge improvement,only getting not convergent in sqrt when close to limits.Great find hiwa

Interesting find!

 

Anyone who knows why this would happen?

Interesting for sure, I usually use 600-620. A tad more with single thread only or OS gets choppy.

600 at 26xx ?

 

This is less than 640 maxmem, but with this ES I have can run 1m/pf all day 2620mhz but cant bench 32m over 2500mhz not exact in round within the first 4 loops.

This was at 620maxmem. I'll give 640 a shot next time.

So can be CPU problem again? 2 CPUS here have the same problem. but one friends cpu can do it with no error at 600 maxmem.

I run 1300MHz+ mem (Samsung) and 600MB Maxxmem and never a problem... but i've not spent a LOT of time with 32M and ivy yet

Hi,this was at 600 maxmem ,seems to be ok at maxmem (600-680)Could just be cpu related

problems seems to increase when using cw - most of the time can pass 600-680 without cw but as soon as cw is in the game there will be many problems. 640+ improves things but without maxmem at all runs will pass much more often...

Did some testing today...

 

I7 3770k

Asrock oc formula

Gskill pi 2200 cl7

 

Memories 2600 8-12-8-28 and maxmem 600 and 640 passed 100% of the times. Did waza 4times and 3 of 4 times crashed. Some times SQR error, last time it freezed at 8th or 9th loop.

 

Seems that here I didn't have problem with maxmem, only when i run a waza run..

if CW causes your 32M stable mems to crash, try loweing the Vmem or raising the Vccsa

Thanks sam will try!
