CAS 5 is real as long as you set it during Memory Training NOT AFTER
you can tell by perf diff immediately

Good to know, thank you Peter

True , but when u bench PSC or some wired memory chip

u will see difference between CL8 and CL7 in OS immediately

CL6~CL5 u need lower TCWL also . Or the eff will be still the same . Even worse.

CL4 is some kind of BIOS code bug ... It will return back to the value u set in BIOS .

Apacer 32GB kits is awesome . 2854 12 13 13 35 still going ..

vdimm?

1.65 only .. it really awesome kits

damn congrats ...well done

So I can replicate my vdimm issue without a hitch, if I set any vdimm north of 1.8 (1.805+) it reverts back to 1.713v, however every value including 1.8v and below sets correctly, this was tested on the latest bios (1.15B&D).

[emertX]

do you have an ean-code?

[l0ud_sil3nc3]

vdimm?do you have an ean-code?

Not sure I understand?

[emertX]

Sorry...I meant nick...what is the productcode from the stix? I can't find them anywhere!

Strange . did this issue happen to air cooling or LN2 cooling ? I have sent u msg , please check it . hopes it will help u.

well... what wrong on my setup for try to play CL5 & CL6 on this board ??? i have better results from CL6 over CL5 at 2400MHz and PSC chip
and for other subtiming all same setting

2400MHz 5-11-8-24-1T, 1.85V (air )


2400MHz 6-11-8-24-1T, 1.85V


and.... not only on high frequency of RAM to see different but i back to try with normal clock at 1600MHz compared by 5-9-9-24-2T and 6-9-9-24-2T
(used 2T for lower Vdimm ) all subtiming are same and it same case like above CL6 still better over CL5 and big different as well for Spi32M from two time running

CAS5 - Spi32M first run 07.31.044s | second run 07.30.685s


CAS6 - Spi32M first run 07.28.907s | second run 07.27.845s


btw. 1.15D nice one for PSC ram kit Nick

hey bro . U need to set CL5 in BIOS . then u will see CL5 get boost .

TCWL need tight also . This one can be set in OS

[nickshih]

damn ur bbse is awesome -.- ..... i got ty bbse here haha...

Lastest BIOS and Software . bios: 1.15D software : 0917

Yes, i set CL5 in bios and boot direct not set in windows and for TCWL maybe my ram can lower 8 i already try to low
but it crash

TCWL is the key ...if u cant tight it ... then cl5 will be slower ....

u can try to loose some subtiming .. TRRSR TWWSR etc.. some cant be 1 . only 2~3 is proper . it is depends on ur memory .

Nice start, now let's see 32M action iso 1M

I tought tRRSR and tWWSR are lowest value 4 Nick ? Doesn't setting a lower value result in eg value 7 ? Nice work on the DIMM compatibility ASRock ! Top Job !

ha i just mean sort of those subtimings .... TRRSR and TWWSR lowest is 4 when u set higher than 2400 for sure....

[nickshih]

For example , this pic is performance level 5 in bios . U can also choose performance level 4~1 to tight those timing automatically depends on the memory ability.
