Hello everyone,

i am new to the world of overclocking and was wondering if it is possible to push my CMH32GX4M2D3600C18 sticks any further even if it is just tightening the timings of XMP if that is even possible?
my rating for xmp is 18-22-22-42 for 3,600myhz at 1.35v
ive been playing around, I have XMP Disabled and set the Frequency to 3,866. (highest i could boot into windows with was 4,300mhz)
I have enabled Round Trip Latency, Disabled Power Down Mode and and set CPU SA and IO to 1.350 (max for now so i can lower later on after finding timings right?)
my DRAM Voltage is set to 1.50 also (Will lower this to) I am able to boot into windows with these settings, used Testmem5 on these ratings and passed.
18-20-20-40 3,866mhz passed on testmem5
17-20-20-39 3,866mhz passed on testmem5
16-20-20-38 3,866mhz passed on testmem5

Is what I'm doing on the right track? any direction would be most appreciated.
I only use my PC for Gaming and sometimes streaming also with OBS.
My pc Specs are
MOBO - MSI MAG TOMAHAWK z490
CPU - i9 10850k
PSU - GameMax 1000w gold rated
GPU - RTX 3060 ti oc edition gigabyte
RAM - Corsair Vengeance RGB PRO SL 32gb 3,600mhz 18-22-22-42
COOLER - Corsair h115i Platinum 280mm
Two Corsair LL120 Fans as Exhaust Fans.
AIO Is mounted to top of case
4 Fans at front of case also.
 
I have got my settings at
DRAM Frequency - 3,866mhz (XMP DISBALED)
DRAM VOLTS - 1.450 (cant get any lower or TestMem5 shows errors)
CPU SA volt 1.150
CPU IO volt 1.100
Timings ive went down from 18-22-22-42
to 16-20-20-38 command rate 2N
tRFC set to 550 (lowest i can go with out BSOD or errors on TestMem5)
tREFI set to 65535 (not to sure what to set this to but works with this)
I have Disabled Power Down Mode and Enabled Round Trip Latency.

IS THIS A SAFE AND OKAY OVERCLOCK FOR DAILY USE? and is this even worth using over my stock xmp profile at 3,600mhz 18-22-22-42?

Was 4300 not stable?

No, i couldn't lower the timings from 18-22-22-42 that much think i got 17-21-16-40 lol but to me that sounded wrong... and i think it errored on TestMem5 i did that two days ago, i was up all last night testing with just 3,866mhz and ive got it all stable i think been on warzone for 5 hours aint BSOD yet i stress tested on aida for a hour before hand.
does my timings ive set for 3,866 look okay? could i improve
 
Whats the version number of the ram? should be in the format vX.XX where X are numbers. 1.5v might be too much depending on the die- but focus on subtimings and frequency first rather than primaries. Set 1.35vccio, 1.45 vccsa and see how far it goes frequency wise running an imc stress test such as ycruncher n32/n64 or occt large avx2. Then you should start tightening timings.

Where would I check for version number?
And I have set my sa and io to 1.350 each then was lowering them down and testing each time for stability.
With 3,866 I got sa and io down to 1.150 and 1.100.

I'm able to get to 4,200mhz with my normal timings of 18-22-22-42 and passed testmem5.
4,300 would throw me errors, should I try see if I can lower 18-22-22-42 with 4,200mhz? And what should I try lower them to.

Version number is the box outlined in red, on a good IC your cpu should be able to handle 4400Mbps+. Also testmem5 alone isnt good enough, you need to test your memory controller too. Are you using any specific configuration or just the default by Serj config?

I have just been running default config on testmem5.
i ran memtest64 for 5 hours on my profile using 4,200mhz at 18-22-22-42 tRFC 550 and tREFI 65535 with command rate at 2N , Power Down mode disabled , Round Trip Latency Enabled.
CPU SA at 1.180 and CPU IO at 1.240 and DRAM voltage at 1.490. is 5 hours on MemTest64 enough?
what are free programmes i can use to further test for stability with 4,200mhz ( i don't think i can do any higher with my sticks) Thaiphoon says my sticks are 8gb E-Die (z11-b/ 19nm) / 1 die ( aint got a clue what that means lol)
Is what i already have applied safe ? or will i **** my sticks up :( haha i have spare 2x8gb sticks same sticks they say the version is 8.31 ( i need to open my pc case to see the sticks inside but they are the same vengeance pro sl 3,600mhz 18-22-22-42 1.35v cl18 )
