Memory speed depends on how much memory you have. For me with all 8 slots populated and maxed at 128GB I can barely hang around 3000 with the rated 14-14-14-34. Anything higher would require some serious bump in VCCSA which I am not comfortable with at all. Maybe my 6950X has weak IMC.

Decided to go with a 3600 samsung B-die kit F4-3600C17Q-32GTZR - for future upgrade of the cpu/mobo. It is Samsung in cpu-z.
There is also a 4000 kit, but that kit has Samsung and Hynix versions and more than likely would end up with Hyjinx kit realistically due to the price of it.
Did a 3200 run but VCCSA melts the cpu on auto settings (1.4 V)
Having done any tweaking yet. Not overly concerned anymore, this is a 6 year old platform.

Guys is there someone who mixed memory modules on haswell-e.
I would like to mix a 2666MHz c16 four stick modules with a 3000mhz four stick modules with a total of 8 stick.

I will run the memory at 2666 c16.

Do you think that can it work?

Hi,
Never know until you try
Do the two different corsair kits have the same Ver# on them ?

Thanks for the answer. No I don't think so.
Kit will arrive tomorrow. Will see. :)
Hi,
Different Ver# means different chips which corsair is famous for even at the same speed and if so they may not play well with each other.

A bit dusty, a bit old but I still love my Haswell-E.
It drives my 2080ti well in 4k and it will drive my next 3080 until the arrive of DDR5.
I know that DDR5 will have few sense at launch but I refuse to buy a new pc now with DDR4. 😂

Said that.
I had 4 sticks of Corsair Vengeance 3000mhz cas 16, but my 5930K don't want to run memory higher than 2666MHz so I bought another 4 sticks of Vengeance 2666MHz and paired them with the 3000MHz sticks.
Now running 8 sticks @ 2666MHz CAS15 and it seems to work great

Hi,
Did you take note of the ver # on the old and new sticks ?

no I don't know the old version, newer one is 5.22 but I bought the first kit in 2014 so I think that the version differs.
Hi,
I had a set of 2666c16 ver 4.23 that were pretty good and another 2666c15 ver 3.21 that were total garbage.

my 5930K can't really handle good memory since it can't handle anything better than 2666MHz so every sticks is good for that CPU :D
Hi,
I thought that too but then got some 3200c14 4x8gb kit and boom worked like a charm on my 5930k.

Testing 3200mhz 2T 13-13-13-33 1.35v.
Passed 2 different memtests so far, and an hour of quake champs for some random processing. Will leave it running for a week or so and wait for a freeze up.
Wondering if it will do 2T 12-12-12-32 1.35v.... can only try i guess.

Hi,
Memtest 86 or 64 are to test for bad sticks not stability of oc'ing or xmp profiles.
AIDA64 is okay and just general gaming.

It ended up bluescreening ntfs.sys
Probably needs more volts than 1.35
Reverting back to cl14
