i7 930 OC Question

I just recently got a new CPU cooler for my i7 930 and have successfully over clocked it to 3.8 GHz on stock voltage. I don't plan to go any higher b/c I'm right where I want to be as far as temps go, and I am happy with the OC.

My question is whether it matters if you achieve the overclock through increasing the clock frequency or the multiplier. Reason I ask is this. Right now my clock frequency is at 174 and my multiplier is 22. Doing this forces me to use a lower ratio on my RAM frequency as I don't want to use to high of one and overclock my RAM to much. I'm right in the middle with my RAM frequency, so if I could lower my multiplier just a bit and increase my clock frequency a bit I could achieve the OC I'm looking for on my RAM which would be right around 1600 MHz as that's what it's spec'd for.
 
Try both scenarios and see which is best suited for what you want?

To be honest, ram speed doesn't matter a whole lot for real world performance, or not that i've noticed.
 
You should have a mem multi to get you at ~1392MHz which is probably fine. You could lowering the timing on your ram, but I doubt you will see much performance difference from that or by getting to 1600MHz.
 
lower MHz with lower latency sometimes performs even better than higher MHz with higher latency:) but just like the others said, you won't see any difference in most real life apps. only difference you'll see is the benchmark numbers.
 
Gotcha, and that's what I was kind of wondering. Yes, 1392 mhz on my RAM is correct. If jumping that up to around 1600 won't make any difference that I'll be able to tell I'm not going to worry about it.

Thanks for the feedback guys, very helpful.
 
I'd try 200x19=3800Mhz.

Then if you set the RAM multi to 4x it will run the RAM at the rated 1600Mhz. (200x4=800MHz double pumped to 1600Mhz.)

I originally did 23x185=4255MHz (I7 950 though.) but that meant I had to under clock my (1600MHz) RAM to 1480MHz (Works obviously.) or OC to 1850MHz, which it threw a fit with.

I've found my new settings to be very stable compared to the old!
 
With my i7 930 I had to push QPI to 1.4 to get it stable above a 185 Bclock on my P6X58D-E for reference. Im now at 4.2GHz with 1.35 Vcore

@Little_4nic8er what are your temps like with 1.4vcore and the H50?
 
Using CoreTemp to monitor it normally idles at 37-40C depending on the temp in here. (Currently 40C with a 20C ambient room temp.) It goes up to 70C when I stress test it with P95 64. Most games hover around 45-50C.

I want to move to true water cooling but I have to move soon and my rent will double at least, taking away from my toy money. :( Rent is dirt cheap ATM but it wont be when I move.
