Overclocking RAM?

Hi.
I've had a 3770k, ASUS P8Z77-V deluxe and Mushkin 1600mhz 1.35v RAM for a couple of weeks. Had the Processor at 4.5ghz at 1.185v for most of that time, and I've been wanting to try and squeeze a little bit more out of it, as I feel I do have around 20 degrees with temps, and quite a lot of CPU voltage to play with.

I can push to higher clocks, but have to go to around 1.35v to get stable at 4.7ghz so I dont really see that being worth it for the increase of heat and voltages.

So, I've been trying to overclock the RAM. The RAM is rated at 1600mhz, and from trying to push it up to 1866mhz, it just goes straight into boot loops.

Anyone have any ideas how to get anything stable higher than 1600mhz? At 1800mhz it boots to desktop then bluescreens, so it is kind of managing that, but I have no idea how to get anything stable.

Anyone any ideas? Or is 1600 the most it will do? and then is tightening latencies the most I can do?
 
You need to increase ram-voltage and maybe also vccio and vccsa.
1.35v at 1600mhz is very low,and should give headroom for higher bandwith.

Thanks for the reply. I have increased the voltage up to 1.5v but it still doesnt let me go higher. I'll try the others.
Thats what I thought about the headroom too, also why I bought the LV version, but it doesnt seem to want to go higher :/

If it's a little TL;DR then i'll sum it up here; I too thought that the low voltage modules would overclock well because of their voltage headroom, but it was mentioned how such memory modules are more than likely binned for their lack of overclocking potential but their ability to run at low power.

Hope it works for you, though :(
 
1.65v on ram.If that doesnt work try 10-10-10-28 also at 1.65v.
Maybe it would be better to try to tighten timings instead at 1600mhz.
 
I have Ivybridge so I dont really want to push the RAM over 1.5v tbh.

Is it better for performance to get 1866 or tighter timings?
 
Both IB and SB likes bandwith,but it looks like your ram wont play above 1600mhz.Tightening timings will give a better overall performance.
Maybe you could try 8-9-8-24,1600mhz at 1.5v.
 
If youre lucky,try 8-8-8-24 or 8-9-8-24-1T(N) at 1.5v
You could also try to lower volts on vccsa and vccio to get better temps.
What is the default(auto) cpupll voltage?
 
1T(N) is that 'DRAM COMMAND Mode'? If so, that's already on 1.

I think i'll go for the lower voltages though, not that it matters too much, as temps arent high at all.
The PLL voltage is 1.816v on Auto?
 
Yep thats the one.
Lower cpupll could in some cases get some better temps,but to low will also affect stability.
1.816v is good enough though.
