Haswell-E Cache/Ring OC

[thatKingKong]

Have anyone here able to OC the Cache/Ring speed higher than 3.6Ghz on the 5820K, higher than 3.7Ghz on the 5930k and 5960X? Thank you!

Some golden 5960x chips can do a 1:1 cache to core clock speed as high as 4.6ghz. Reading over threads of users results, most seem to top out around 4ghz for cache speed. Setting the cache on my chip to anything over 3.9ghz crashes my system.

If you want to go crazy on cache voltage you can likely get it up to 4ghz and higher though. I had to play with the voltage quite a bit and the cache overclocks a lot better with manual voltage, not using adaptive or offset settings.

Have there been any benchmark results for cache overclocking?

If you want to clock the Cache higher than 3.5Ghz on Haswell-E than you need to buy an Asus Board with the OC Socket.

There are 3 boards available with that Socket in it.
Rampage V, Deluxe & I think the Workstation one is the 3rd one.
I am not sure about the last.

It's nothing about a Golden CPU, its about the Socket.

I wouldn't say I have a golden chip but my 5690x can do 1:1 at 4.5ghz without too many issues. That said, it's not a huge difference in performance, probably in the low single digits, nor is it a huge difference in heat output to turn the ring voltage down.

In short, you're not losing anything so I wouldn't worry about it too much.

It depends on what motherboard you use. I could only get 3.5GHz out of the cache on my 5960X using a Gigabyte X99 Gaming G1. The Asus Rampage V Extreme I'm using now runs it at 4GHz just fine with 1.2V thanks to the Asus OC socket. This matches my core clock speed of 4GHz, so it's a 1:1.

There is not much to be gained outside of a few benchmarks where cache has an impact. There are some games that benefit from more cache, World of Warcraft is one of them. It would be interesting to bench a game that benefits from cache at different cache speeds.

Your core clock is not a golden 5960x, those are the 4.7+ stable chips, but your cache overclock certainly is from everything I've read. The silicon lottery of core overclock vs cache overclock can be independent of one another. But, you may actually have an all round golden chip if you are running that 4.5ghz with something like 1.25V. In which case you probably could get 4.7 or 4.8 stable with 1.35v.

My chip is a poor overclocker all round. 1.35V for 4.5 and getting 4.6 takes 1.42. Maybe I'll get lucky and it will die at some point so I can take advantage of the IPPTP and get a better chip down the road

Any revision 1.1 or 2.0 boards out yet that might do better?
