maybe im stupid but i can fill only those

 

RAM CAS# Latency: 10
DRAM RAS# to CAS# Delay: 12
DRAM RAS# PRE Time: 12
DRAM RAS# ACT Time: 31
DRAM READ to PRE Time:
DRAM RAS# to RAS# Delay:
DRAM WRITE to READ Delay:
DRAM CAS# write Latency:
DRAM WRITE Recovery Time:
DRAM REF Cycle Time: 313
DRAM Row Cycle Time: 43
DRAM READ To WRITE Delay:
DRAM WRITE To READ Delay(DD):
DRAM WRITE To WRITE Timing:
DRAM READ To READ Timing:
DRAM Refresh Rate:
DRAM Command Rate: 2

 

if you understand where the others go can you write them

 

now im trying to figure out where those go 

RRD: 6
WR: 16
WTR: 9
RTP: 9
FAW: 26
WCL: 7

Sorry didn't see you already mentioned the manual. Yeah it's kinda hard. Haven't seen this kind of bios in a loong time 😄 

 

tRC = DRAM Row Cycle Time: 43

tRFC = DRAM REF Cycle Time: 313

CR = DRAM Command Rate: 2

tRRD = DRAM RAS# to RAS# Delay: 6

tWR= DRAM WRITE Recovery Time: 16

WTR= DRAM WRITE to READ Delay: 9

tRTP = DRAM READ to PRE Time:9

tFAW = N/A but should be calculated by motherboard in this case (maybe)

tWCL = DRAM CAS# write Latency: 7

 

i think my motherboard puts wrong timing even when i enable xmp, so i want to put the timings manually but i don't understand where to put some of them:

 

AIDA64 Extreme shows that my DDR3 XMP v1.3 timings are those:

XMPv1.3: @ 1200 MHz 10-12-12-31  (CL-RCD-RP-RAS) / 43-313-2-6-16-9-9-26-7  (RC-RFC-CR-RRD-WR-WTR-RTP-FAW-WCL)

 

And those are my motherboard timings:

 

DRAM CAS# Latency:
DRAM RAS# to CAS# Delay: 
DRAM RAS# PRE Time:
DRAM RAS# ACT Time:
DRAM READ to PRE Time:
DRAM RAS# to RAS# Delay:
DRAM WRITE to READ Delay:
DRAM CAS# write Latency:
DRAM WRITE Recovery Time:
DRAM REF Cycle Time:
DRAM Row Cycle Time:
DRAM READ To WRITE Delay:
DRAM WRITE To READ Delay(DD):
DRAM WRITE To WRITE Timing:
DRAM READ To READ Timing:
DRAM Refresh Rate:
DRAM Command Rate: 

 

since i couldn't do it my self, i thought maybe someone else understands where they should go

even with this guide i couldn't do it... https://www.overclock.net/threads/ram-timings-explained.381699/

 

System:

motherboard: asus crosshair v formula z(990fx am3+)

cpu: amd fx 8350

ram: g.skill trident x(F3-2400C10D-16GTX): https://www.gskill.com/product/165/173/1532068057/F3-2400C10D-16GTX

the motherboard might not support certain settings. You can try setting the values provided in AIDA64 Extreme and leaving the rest on auto. While it might be possible to achieve 2400 MHz with overclocking, you might experience instability or other issues.

i tried 1200MHz(2400MT/s) at 1.65v with first 4 timings 10-12-12-31 2T and its stable, without issues

but i want the rest of the xmp timings to be right aswell

 

i don't know where the rest of the timings go (RC-RFC-CR-RRD-WR-WTR-RTP-FAW-WCL)

Its short for this, including, CL-RCD-RP-RAS, some of them is in the same order.

nvm i will put only those

 

RAM CAS# Latency: 10
DRAM RAS# to CAS# Delay: 12
DRAM RAS# PRE Time: 12
DRAM RAS# ACT Time: 31
DRAM REF Cycle Time: 313
DRAM Row Cycle Time: 43
DRAM Command Rate: 2

 

rest auto from motherboard

 

i think i saw worse performance when i change WR from 14(auto) to 16 and WTR from 7(auto) to 9
