Silly sandy to ivy question

post #1 of 12
Thread Starter 
I ran DDR3-2133 on my sandy bridge with just a higher dram voltage

the same voltage / clocks did not work on my ivy

i had to drop to DDR3-2000 on my ivy


Sandy's imc was limited in the amount i could overclock, i see ivy lets me go way further.
while my ram doesn't allow it, on an ivy chip would this ram OC require the cpu to use any additional vcore?

curious to hear some responses, i'd like to know before I set ram to 1333 or 1666 and start lowering vcore

Vcore has nothing to do with RAM overclocking. You're principally going to be adjusting DRAM voltage, and possibly Vccio needs to be tweaked just a little bit. If you were able to run 2133 on your SB platform, you should be able to attain the same on the IB platform.

thanks for clearing that up, some other users confused me a while back

yes unfortunately i can not run the same ram overclock on the IB that i did on the SB, wasn't ever able to find a solution.

loosening timings, more dram voltage, added vtt, nothing allows me to run the same speed. i dropped down to ddr3-2000 because it seemed to work and i had to settle for that.. i couldnt get 2200 or 2400 stable at no cost and after adding alot of volts in many places i gave up

guess im stuck at 1000mhz biggrin.gif still would appreciate if some others share there experience, maybe something similar happened to you

2133Mhz works without any issues for me after going from 2500k -> 3770k.

Same timings and same voltage smile.gif Maybe the memory controller gone wacko?

Just wondering what on earth do you do that scales with increased RAM speed?

Would the difference between 2000 and 2133 even be noticeable?
