F4-3200c15q-64gtz and rampage v work together?

[pphx459]

Hi, I'm looking to upgrade my ram to a higher capacity, currently have a competitors set (4x4 3200 cas 15) running flawlessly. Would this set work with rampage?

Yes, no problem with the latest EFI. Of course also considering you have a CPU capable of these specs. Usually a 5960X is required.

[pphx459]

ok great thanks, yea I have a 5960x. Dunno if it can handle 64gb, but it can 16gb.

Ooops, forgot to ask, if XMP is used, what is VCCSA set at? Thanks

[GSKILL TECH]

You should be able to see if when you enable XMP

There are two voltages, one is DRAM Voltage, the other is VCCSA

[pphx459]

Yea, I know, just wondering what it is that XMP will set it as before I purchase.. kinda trying to make an educated guess to see if my CPU can handle it.

Soo... just got this kit this weekend and some initial testing were not positive. For the life of me I can't get 64gb to be recognized at 3200. I've tried VCSSA from 1.1 all the way up to 1.3 in .1 increments.

Here's what I have with 1902 bios (someone suggested using an older 17xx bios?)

5960x @ 4500
Vcore: 1.315
VCache: 1.256
Input: 1.9
Strap: 100
VCCIO: 1.16
VCSSA: 1.1->1.16
DDR Voltage: 1.365->1.375

I haven't tried the different system agent voltages with 3000, but if I back down to 2800, all modules are detected.

Any ideas on what I can try?

I've managed to get this to run at 3000 and it recognized 64gb , but I can't replicate it now. This is with bios 2001. ON the other hand, after testing these all weekend, I realized I can run my 16gb 3200 at .95 VCSSA. Would I be better off with the 8x8gb (Model F4-3200C14Q2-64GTZ) instead? I've read somewhere that lesser density modules may be better for the x99 platform. newegg also has reviewers saying they run at the rated specs.

Either way is good, the motherboard and CPU you have will basically handle everything

What is your VTTDDR Voltage? When you change DDR voltage you should probably manually change VTTDDR to be half of that.

And I'm pretty certain you will need a higher VCCSA than that, 1.25-1.3V, when using 8x8gb kit like that. just for 4x8 3200 vccsa will usually need 1.1-1.2v

And the last part of your post confused me. If you're doing 3000 you probably will need to try a strap/bclk of 125.. but you said you were doing 3200 - which 100 is good for.

Are you manually changing timings?
