Hi 8 Pack or anyone else for that matter can help,
Recently got a new system (see sig) and i love it:D it's my first intel system after using AMD for a long time and the performance difference coming from my fx4100 system is insane.
The issue i have is that i've never overclocked an Intel rig before..
After having a look in the bios there's plenty that i recognise but i guess i'm a little scared on where to start.
Can you help me with establishing a base to start for please?
Current cooling is an arctic freezer 13 but i do plan on getting a water loop setup after upgrading my Gpu when the new AMD cards hit.
I'm not after crazy speeds but 4.4 would be great until i sort better cooling;)

Thanks
David

The simplest start is to set the vcore to 1.25v, change the LLC setting to something near the maximum, and set the multiplier to 46. The chances are this won't be stable, so drop the multiplier until it is. You may well need more than 1.25v to get 4.4GHz stable (mine needs 1.31v), but you'll get temp problems quickly without high end cooling.
 
Which Vengeance Pro RAM??

Good starting point for around 4.5 is 1.25 Vcore.
So into bios. Set XMP on the first setting. This sets up your RAM.
Then set turbo ratio by all cores and key in 45 to give you 4.5ghz.
Set cache Ratio to 43 for the best possible perf stability option. Lower to 42 if needed for more stability.
Move down now to Vcore and set manual and key in 1.25v,
On Cache Volts set 1.25v also.
Depending on your RAM will depend on what SA, IOD and IOA are needed. Often auto is fine but with high speed RAM and low latency adjustment may be needed.
This should be enough to start you off.

For stability testing just use the machine!!!!
 
Well i tried a fair bit of gaming, everything went well tbh, tried arma 3 but even with a full server and the view distance up full, i found that it hardly uses this 4770k.
So switched to BF3 and a full server, played a couple of games and again went well.
My only concern is temps, max temp was 77c? whats the max safe temps of these cpus?
Thanks again 8 pack.
Oh one last thing, was that a "no" to dropping the vcore or leaving the ram @1866?

Edit-Does this score and associated pics look correct?

Just set max. This is what kicks in when windows boots. NB speed is not linked to speed step its constant. NB at 8 constantly will cripple perf. For 4.5 set 42 as max. Done!!

Temps are fine as is core dont worry about em.

They can handle up to about 90c-95c, at which point they start throttling. I wouldn't want to run it that hot 24/7 (I'd be worried about degradation over time, though I'm not entirely sure at what point a chip does start to degrade) but you shouldn't see those temps under regular load anyway. Benchmarks and stress testing tools can easily get you to those temps, but you wouldn't be running those 24/7 anyway.

77c is fine anyway, it can handle it.

If its stable at 4.5 on both should I leave it there or will 4.5 cpu and 4.2 cache still be a better oc in the long run?
 
Well after a long session gaming today i'm happy to report that i've had zero crashes thus far:D
stable at 4.5, my cache ratios are (min 39) (max 43) vcore @1.232.
that ok 8 pack?
There's so much more settings in the bios that i don't have a clue about like extreme tweak etc anything else i can change for more performance?
Tbh i've not really noticed much gains in gaming, but i guess my gpu is the bottleneck now as it's constantly maxed at 99% usage.
Edit- things like speedstep, all powersaving settings etc are enable, should i disable these?
And is it better to use adaptive voltage rather fixed?
 
Me again,
After watching a few Asus north america vids he recommend running the cache frequencies in sync if possible with the core for max performance?
Well i have not sync'd the core and caches to 4.5 and everything seems fine.
can you confirm this 8 pack?
Thanks
david
 
For sure 100% cache ratio is absolutely the best for performance but it can cost stability and diminiishing returns are seen after a certain value. At 45 ratio your normally very very close to max at 43 cache. But yes full cache is best.

A good e.g of this is 6.5ghz 32m with 5.6 Cache is nearly 3 seconds slower than with 5.8 Cache. Which in 32m is quite alote How ever 6ghz cache is then like 0.3 seconds faster than 5.8.

All your settings are fine nothing to worry about and temps for Haswell are fine also. Most clocked Haswells are higher.

i have my cache at min 8 max 45 and it downvolts the cache when it clocks down to 8 (at idle). less power used, less heat

theres no performance loss, as with regular speedstep, when its needed it ramps back up.
 
I'm jealous of these results, I need 1.31v just for 4.4GHz (though I can run 4.3GHz at 1.2!). I've found for me that higher cache speeds definitely cause problems, even with the voltage raised, e.g. cache at 4.2GHz is 100% stable, at 4.3GHz I get crashes under high load.

I'm guessing i've just got lucky tbh, although i've not tested on anything like prime95 etc.
All my games run great without crashes so fingers crossed, temps have altered too where i think the AS 5 needs time to cure so chuffed to bits really.
I did try changing the Dram command rate to 1t instead of 2t and got a crash on arma 3 mind so that's gone back to 2t.
I don't know how different are boards are, maybe that's it? i don't know.
 
It's the CPU - some 4770Ks will only manage 4.3GHz no matter what you throw at them, others can get to 5GHz fairly easily. You've definitely got one of the best though.
