Corsair Dominator Platinum 3200MHZ RAM & 5930k Problems!

Hi guys,

So I initially had a 5820k and 32GB of Corsair Dominator Platinum which were rated at 3200mhz, after a very long time of trying to overclock and enable XMP profile to work. I managed to get maximum 4.3ghz on cpu at 1.3v and 2666mhz on the ram with XMP on. Is this normal?

I've recently upgraded to the 5930k and I've found that I'm able to get 4.5ghz at 1.25 and max 2800mhz on the ram before it gives me boot issues and doesn't post. The ram is rated at 3200mhz using XMP, however I cannot post with this enabled and it gives me problems, so my question is will I be able to achieve 3200mhz at all and how exactly? Or is it a case of the actual processor and the memory controller within it being weak? Will the 5960x allow me to have 3200mhz as it's better? Shouldn't the RAM work at 3200mhz if its rated at that on the box?

Or is it a case of silicone lottery between the CPUs?

Also the bios i'm using is the latest 3501 and motherboard is rampage V extreme.

Hope you guys can help.

Thank you! 🙂

There is many newer ram kits what is not in qvl list and should work fine like my g.skill tridentz 4x8gb 3200mhz cl14 kit. What i test 2 ram kits on qvl list xmp not work straight out of box and needs lots of tweaking when ram is over 3000mhz. In your case 100mhz strap is fine try increase vccsa, Cpu core and cache voltages when it stable. Manual adjust your memory timings don't use xmp.

Should, would and could work is not what someone who is looking for plug and play wants to hear. Especially when the example given is not even the same kit.

I tried orange juice in my weetabix this morning, you don't see me mentioning that here.

As i say there is no plug and play when ram is overclocked. Even my one qvl listed 3000mhz memory kit fails with xmp and need lots of tweaking to get stable.

Thanks for your replies guys! I shall try them things and let you know!

Go into DRAM timings and set the very first thing in there to MODE 1. It helps soften up the timings a bit. Also make sure you are running that kit at 1.35 v. I have the same CPU and very similar RAM. I had to go in both DRAM timings and in the Extreme tweeker and manually set the voltage to 1.35 volts.

Hopefully between the voltage and using MODE 1 you should be able to get a post.

There was one version of BIOS that I couldn't get a stable XMP boot and actually had to increase the voltage to 1.38. Like you, my RAM isn't on the 'list', but a little tweaking you should be okay.

Holy F***, thank you so much. This actually worked!

I set the Rampage Tweak Mode to 1 and now finally it works fine with 4.5mhz CPU at 1.25v, 100mhz strap and 3200mhz RAM. For a very long time I figured the RAM was incompatiable, the mode was initially on auto so it went to Mode 2 or Mode 3 which caused it not to boot which is weird. I would have assumed that when enabling XMP it would automatically change the Tweak Mode. Asus should really make this more apparant some how that you can change the Tweak Modes which support compatiablilty and overlclocking etc. I literally searched everywhere online and nobody told me to do this except you.

Again, thank you! I can now run XMP at the advertised rate and not a waste of money.

Also thanks to everyone else who commented or tried to help. 😄

Yeah Mode one is designed for higher HZ RAM kits. Mode 2 is for overclocking.

Glad it worked for you. 🙂

I just wish somebody told me this a lot sooner, I've been searching for an answer for nearly a year... Never even knew this Rampage Tweak setting existed.

Cheers! 🙂

Hello

The board's user manual states that Rampage Tweak Mode 1 is for memory compatibility.

Yeah this is how I found out a bout it. I read the manual looking for an answer, who ever reads the manual tho? 🙂
