Crosshair IV F + Mushkin 2x4gb Black Frostbyte 1600mhz CL9

[x3style]

Hi everyone,

i've been helping people out around here and now i guess its my time to ask for some help on my end

I've recently purchased some components to upgrade my system.


Here's my new specs.

New Components:
Crosshair Formula IV
AMD Phenom II 1090T x6 Black Eddition
Mushkin 2x4GB Black Frostbyte 1600mhz CL9
Sapphire HD5870 1GB Vapor-X
NZXT Phantom Case Black

Old Components:
Cooler Master V8 - Replaced Fan
Cooler Master Silent Pro 1000W PSU
2x2TB Samsung Spinpoint F3 5400rpm
1x2TB Samsung Spinpoint F4 5400rpm
1x1TB Samsung Spinpoint F1 7200rpm
1x120GB OCZ Vertex 2E (System Drive) - W7 64bit

My Problem:

The memory defaults at 1333Mhz and boots up perfectly i use CPUZ and it shows XMP to have the folowing config:

-800mhz(1600Mhz Dual Channel) 9-9-9-24-33 @ 1.65v

If i set bios to 1600Mhz and let auto voltage windows does not boot it freezez at Starting Windows (No Moving lights on the windows logo)
Same goes if i manually type the voltage to 1.65V

The only way it boots is if i let it at 1333mhz or under.

Any ideas on this how i can get my memory to boot up, i willeventually get memtest and start testing it but i would like to know how to tackle this, maybe increase of voltage? I dont wanna burn my modules. What are your past experiences?

Thank you in advance!

There's some sort of "profile" settings in the BIOS. This has to be set to "Standard". If yours is "Turbo", or even "Extreme" it could be the cause of instability.

If i remember there is the OC thing to get ram to 1600mhz but it didnt work either i will check to see.

Also i don't have instability problems, i just cant boot with my 1600mhz ram set to 1600mhz. I can only run the system if i have them set to 1333mhz, and this is frustrating as i payed a premium to have them 1600.

Everything is set to default, standard or w/e they just don't wanna go to 1600Mhz anyone else got any ideas on what the problem is i could send back my ram.

Ah I see.
My experience also this. When I increased my motherboard's FSB from 266 to 400, my computer freezes at that point too. I guess it was lack of CPUvoltage (VID). Also my guess is that there's somewhere in the BIOS that "sync"-ed your motherboard's FSB to memory speed (DRAM). This sync-ing makes it into ratio, like, 1:1, 1:2, or something else.

So it's probably caused by increased motherboard's FSB, direct or indirect way. You can try to upping voltage on CPU (VID) for this to compensate increased FSB. Push it notch by notch, but not exceeding the safe voltage level. I forgot what the safe level is, but maybe 1.4V? You can search the forum or google about safe VID level. Also try to to try to turn-off this "sync" option somewhere in BIOS to "break" the ratio of FSB : DRAM.

Pff, i've checked the manufacturer's website on memory compatibility as i suspected something and it turns out they have a very small text with a * that states "* for LGA 1156 motherboards only!"

I'm talking right now to return my memory and purchase better ones.
