4770K CPU Cache Ratio ?

[Dicehunter]

I was recently watching a video on the tube and it explained to try and get the "CPU Cache Ratio" close to the multi for best results, Sort of a 1 to 1 ratio, I had a look and couldn't find it.
Should I just leave it alone ?

Generally leave it to auto. Auto should set the min and max cache ratio to the same multiplier as your CPU. So if you are setting a x46 clock the cache mins and max should be set to 46 too.

If you are having trouble getting to the next CPU multi then you can try dropping the cache a little. E.g. if you were trying to get x47 and you were just adding voltage with no benefit then drop the cache down to 46 and see if that makes a difference. You can try dropping it further than that (generally between x1 to x3 lower than the CPU multi may be beneficial but dropping the cach multi will lower the overall system performance slightly).

TO Almost everyone: STRAIGHT UP:
Someone put in the manual and in the GBT BIOS that the Uncore should be equal or higher than the CPU Ratio, that is NOT, i repeat that is NOT going to help you in any way. Lower it in fact, lower it to 35x or even 30x to be safe, then OC the CPU and then start raising it once the CPU is stable. Most of you can probably boot into windows at 5ghz and in windows OC the multiplier with GTL to 52x or even higher, I can, but the issue is I can't increase my uncore over 4.7ghz on air at all. That is a 500mhz less OC I can do on the Uncore than I can on the CPU ratio. The Uncore helps performance because it controls the speed of pat of the cache, however what I stated in my guide and what others don't really realizes is that the cache has double the bandwidth of sandy bridge and ivy bridge caches, which means that there is no reason to match 1:1, I recommend 300-500mhz lower on the uncore to unbottleneck it on air/water, on Ln2 it is better to keep it closer or on benching use the 300mhz if you can cool it. This uncore is not the same as it was on X58, it has a HUGE impact on system stability so watch out. Also only the recent GBT BIOSes can actually change the uncore(raise it over 39x) so if you have been setting high uncore before it wasn't actually setting that uncore. Thank you for reading this, now I don't have to repeat myself 20 times.

Yea...much of the stuff they do is on LN2 @ 6GHz+. Most people are Ocing on air to a mid 4GHz clock and won't need to touch the uncore/cache ratio much. A few multipliers under a 24/7 clock is all you need.
