Can someone review this core i5 750 OC?

[cpp214]

This is actually the 1st time I've ever overclocked a processor.
There are various threads here and elsewhere that do a great
job of describing the steps involved in overclocking the i5, and
I've tried to follow them as closely as I can.

I have the following system specs:

Core i5 750
Gigabyte GA-P55-UD3L
4GB Corsair DDR3 1600 RAM--9-9-9-24/1.65v manufacturer specs.
Cooler Master Hyper 212 (just installed today)
Cooler Master Storm Sniper case
HIS 5850
Corsair 650 TX PSU

I've currently got the i5-750 at 3.4ghz.
To get there, I did the following: (not necessarily in this order)

1. Disabled Turbo boost, C1E, and the other power saving features in BIOS
2. Set Bclock to 170 with multiplier at 20.
3. Set QPI to lowest setting--x32
4. Set memory multiplier to 8 (1440mhz)
5. Settled on CPU voltage at ~1.167v (CPU-Z shows it at 1.20)
6. Manually set the memory timings to the rated 9-9-9-24

I left the memory voltage on auto, and it sets it to 1.5v.
This is less than the 1.65 specified by Corsair for this memory.

Here is a screenshot of what CPU-Z, Core Temp and Speedfan
are showing:

The i5 is idling between 30--37c, and after about 20 minutes of
Prime 95 small FFT's, the max temps were 59, 60, 62, 64c.

I guess my main questions are:

1. Am I going wrong by allowing my mobo to undervolt the RAM
to 1.5v, or is that okay since it's only running at 1440mhz?
Should I have manually set the timings, or just left them on auto?
When I left them on auto, they went to 10-10-10-24.
I thought I would just try and tighten them up a bit.

2. Are these idle/load temps reasonable for this type of mild overclock?
(I didn't measure the ambient temps in the room) And will the CPU
temps actually improve over time as the heatsink "wears in?" I'm pretty comfortable with
3.4ghz, and don't really have a desire to go higher. At that speed, I feel
like the i5 won't bottleneck the 5850. (It does bottleneck it a bit at stock/2.66ghz, at
least based on some gaming benchmarks I did for comparison earlier tonight).

3. Does my CPU voltage look too low, or should I even try to lower it some more?

Basically, I'm just wondering if this OC looks okay right now.
I've only just done it tonight, but for now, it seems pretty stable.
Any feedback would be appreciated, and I apologize in advance
for adding yet another thread on such a common topic, but I didn't see
any other threads that addressed my concerns about RAM voltage/timings
as well.

Nice overclock so far!

To answer your questions:

1. There is nothing wrong with lower voltages for your ram, nor is there anything wrong with tighter timings, although i would test it with memtest to makes sure all is well with that drop in voltage.

2. Your temps are great. They will drop 1-2 degrees as the tim settles.

3. Your cpu voltage is fine, like i said before, theres nuthin wrong with to little voltage as long as its stable. You could try to drop the voltage some more if you wanted, or push the overclock a little further.

I hope that clears things up for you.

Hey, thanks so much Overshocked *breathes huge sigh of relief*

I've seen your advice in other threads and it's been really helpful.
I was just a bit nervous about these settings and needed some feedback.
I'll definitely download memtest and run it to make sure the RAM is stable.
Otherwise, I'm just going to leave it where it is

I'm definitely happy for now. And thanks again for the quick reply
