XMP Profile Help

[TootY]

Hi all,

 

I will try put as much detail into this as possible which I hope makes sense in me the enquiry. I've been tinkering around and never knew my RAM was XMP until speaking with another member on the forum (FACE PALM). I've enabled this open in the BIOS from 'Disabled' to 'Enabled' I don't have any other option like a 'Profile 1'. What my issue is I can't get XMP to work, if I enable the option and restart as normal the system will enter 'Automatic Recovery' screen and freeze at times which I think is similar to the Windows 7 Startup Repair phase, I'm on Windows 10. 

 

What I need to know is what I am doing wrong or what would need setting in order for the XMP to work? In the BIOS I have a DRAM Frequency option, should I just set this to 3200Mhz and leave it that?

 

System Specification: MSI X99S Sli Plus Motherboard, Core i7 5930K, Corsair Vengeance DDR4 RAM, 2X GTX 1080's in SLI

 

RAM I purchased (https://www.amazon.co.uk/gp/product/B01EI5ZH28/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1)

 

My current overclock is at a multiplier of 40 and that's will all auto voltages.

Either overclock or use XMP, never both. It gets unstable otherwise. So set your CPU to stock and leave XMP enabled, if only too verify it fixes your current issue. Or OC the CPU and RAM manually. If you enter the RAM settings manually, the speed isn't the only thing you have to enter. You also need to enter the timings (also called latency) and DRAM Voltage or else the RAM will revert to SPD for the settings you leave at Auto and it'll be very unstable.

See here:

The 3200MHz speed is produced by overvolting the RAM to 1.35V (tested voltage) and alleviating the timings to 16-18-18-36 (tested latency).

The SPD (the default values) for the RAM are 1.20V and 15-15-15-36 at 2133MHz. So if you just punch in 3200MHz and leave the timings tight and the voltage low, I'd be willing to bet a testicle that it's not going to be stable.

I'll raise you a sack!

 

So, if I default all my settings within the BIOS to default and only enable the XMP, that should work - however if I get the same results, what's the next possible solution?

 

Would it require me tweaking it manually to get the XMP working?
