3770k z77 sabertooth + 1866 memory??? help plz

post #1 of 15
Thread Starter 
looking to build a sabertooth z77 with a i7 3770k the onboard memory controller for the 3770k states it is certified or rated up to 1600 my question is will running 1866 memory at native speed on a sabertooth burn out the cpu since the memory controller is only rated to 1600 yet the motherboard runs native speed up to 1866. i already own the 1866 ram just wondering if there is a problem running at that speed or if i should punch it down to 1600 when i build the machine. i read a scary review on newegg since the 3930 and the 3770 have the same memory controller specs i was horrified when someone stated they fried the chip due to running their memory at 2133 or something high like that...... kk thanks for replying anyone that does..

It's very safe because the motherboard makes it work safely. All you will have to do is manually select "DDR3-1866" in the UEFI BIOS (in the Ai Tweaker tab) and you'll be good to go. I would also recommend manually entering in the rated voltage for your memory in the DIGI+ VRM section as well because it otherwise might use a voltage like 1.65V on Auto even if the memory is rated for 1.50V.

 

The person who fried their chip was probably doing something wrong (that's typical of Newegg reviewers who have problems). They were probably also powering their system with a low-quality PSU. I've been on OCN for over 4 years and I've never heard of anyone hurting their CPU by doing this.

don't worry about it, i'm running a G-skill 16g 1866mhz with a 2700k on my Sabertooth Z77. and everything running fine, you could even run a 2133mhz memory also with the sabertooth. just put your ram to 1866mhz and have fun thumb.gif.

Listen to TwoCables. 100% correct.

I run 1866 with no issues. If it wouldn't work, they wouldn't sell it.

these are the answers i was optimistically hoping for. . the only thing that makes me skeptical is why would intel cap their on-chip controller at 1600 it makes me very question face of the processor because i don't comprehend this but if those settings in the bios will make everything mesh then. it is what it is.. i have been ocing amd's for roughly 6 years and am going back to intel since they are stomping amd currently and there is nothing in sight as a response from amd. thank you for helping me with a lil homework on the setup i'm gonna build. well with everyone's response i can only conclude that that person probly tried to oc and upped the vid too high on the cpu. and the issue had nothing to do with there memory speeds. thank you for all your responses.

p.s. if anyone has a link for in depth knowledge on the memory controllers in the i7's i'd be really interested i have looked all over and it doesn't seem like i'm using the right search criteria cus i'm not getting any explanations

What precise model of RAM are you using?

If anything, the RAM voltage matters more than its speed in terms of Intel's specifications. Intel really goes out of their way publicly to insist that 1.5v (plus or minus .075) is the way to go, despite results to the contrary.

They also cap their chips at 3.9GHz, but that doesn't stop people from running them faster - same idea with the memory. They have to pick a "stock" speed to support, and they picked DDR3-1600 for Ivy, but that doesn't mean it can't safely run faster RAM speeds. The speed isn't going to damage anything (although high voltages might) at worst you'd get memory errors.

given the intense upgrade this system will be once built i see no reason to overclock it so with my crucial mem volts stock at 1.5 running at 1866 i should be golden since that is the factory setting and my greatest reason for the upgrades is i want full pci-e 3.0 support and full sata3 throughput my ssd is being bottlenecked twice over. it's a sata three connector p[lugged into a sata 2 port and the nvidia chipset is limiting the throughput to sata 1 speeds. also the only cpu's with pci-e 3.0 standard that i have read are currently the i7 3rd generation. would love to grab a 3930k but thats only 2nd gen and the pci-e instruction set is for 2.0. are there any rumors on when there will be 3rd generation i7 hex core releases??

Yeah, 1866 @ 1.5v shouldn't be a problem at all for your hardware.

I have had my i7 3770K since they where released running 2133MHz ram with no problems. I've now moved to 2400MHz ram at 1.65v, And it's still running fine thumb.gif
