Help with getting this pc up to speed

post #1 of 18
Thread Starter 
just put together a new machine.

intel 2500k
asrock z75 pro3
8gb 4x2 gskill ripjaws 1866
msi hd 7970
rosewill 500w psu
visiontek 450w dedicated graphics card psu
500gb hdd

ok so on first boot i entered the bios, was able to set the dram frequency to 1866 and it ran fine for two days. today i was going to take my first dab at overclocking the cpu. this is my first intel build and asrock board. anyway, after entering the bios, i noticed my ram running at 1333. when i select the dram frequency tab, only auto, 1066, and 1333 are able to be selected. doesnt even display 1600 and 1866 anymore. i'd like to get this memory issue fixed before i start asking questions about overclocking the cpu. this new bios is weird. any help would be much appreciated.

enable XMP profile and it should set the correct memory speed & timings.

Are you familiar with the asrock bios? I cant find anything related to xmp. Just the dram frequency, which doesnt list the rated ram speed. This bios is new to me and intel settings are new as well so some things im not sure what im looking at.

Ok i remember seeing those settings. Thats what i set before. The thing is now they are not even listed in the bios. They just disappeared. When i get off work, ill see if i can update tne bios and clear tne cmos. Hopefully that does the trick. Any reason why they would disappear from bios menu?

bios is already up to date. clearing cmos did nothing. load xmp profile option is completely missing from my bios menu.

can you go into your Bios and then 'OC Tweaker' then 'Dram Settings' and take a snap picture & post it?

yes. i set the timings to 888 since i cant get to my rated speed. also one more thing to mention, i also cant overclock. cpu ratio can only be set to auto and "allcore." if the multiplier is set to anything over 37, it will revert back to 37 as seen in the last pic. even at 37, cpuz shows it clocking at 3.4 when prime is ran. super frustrated.

done a lot of reading on this and it is a bit unsual. Officialy, your board supports up to 2800MHz memory speed and it supports overclocking the CPU as much as the Z77 chipsets......
Which Bios did you update? 1.4 is the last one available, is that what you flashed?
post #10 of 18
OP, could you please link the specific memory kit you are using? I'm downloading your MB manual in the meantime and will edit this post in a few.

Edit: Needless to say I own a Z77 board and not a Z75, but I can't seem to reproduce this in anyway. Did you load UEFI defaults after flashing the new bios? Again it would be helpful if you listed your specific memory kit.

Edit2: I'd reflash and do so within the UEFI via Instant Flash (Rom). The reason I say this is because your last screenshot looks nothing like the ones I've seen on Tweaktown and elsewhere. They were on 1.40 and it would seem they have an XMP setting that you currently don't have.



Edit3: Can you see if it works with only two sticks of memory? (Make sure you use Dimm A1 & B1)
