Timings

post #1 of 7
Thread Starter 
Finally happy with my OC vs Temps on my i7.. have never messed with memory timings. Guess this my next phase in OC'n. My question is. How much performance gains can i look at seeing by tighten my timings? Im using, 6gb (2gb x 3) OCZ Gold 2000mhz DDR3 . Which are running at 760mhz, 2:8, 9-9-9-24. Noob in this area so all info will be helpful . Thanks in advance

Can you mess with the divider to get them to run closer to the the full 1000MHz?

im sure i can, i think, my board/bios lets me do about anything.. but is messing with my ram speed gonna cause me to have to tweak my cpu oc to stay at 4ghz? My ram speed right now is on auto based of my cpu Multiplier / bus speed

It might, to run closer to 2000Mhz you would likely have to turn up the VTT voltage a fair bit for stability, & that would make a bit of extra heat.
But just adjusting the memory multi & uncore frequency won't affect your cpu multi or bclk, so if you have a bit of headroom for temps you could be good to do it.

im at 68c max at full load on a hot day in SoCal, so i have head room. what should i start at on the multi & uncore.. and what should i use for stability testing ? like i said straight noob in the mem dept.

The memory divider at 2:10 should put you at about 1920mhz memory, you can leave the uncore on auto it should change to double the memory speed.
The VTT voltage can be the tricky part, some 920s need more than others, for me at 1600Mhz memory I need 1.26V for my 920, for 2000Mhz memory i need 1.44V, you can start at 1.44V & if all is stable try to reduce it, if it needs more I'd go up (in increments) to maybe 1.5V max.
If it needs more (some do) it might be a bit too much for 24/7.
Keep an eye on temps as you go.
