With the i5 6600k Ring Max is at 3500MHz and system agent is at 800MHz, just wondering what speeds of the i7 6700k is?

VCCSA and VCCIO have been variously described to have safe maximums of either {1.20V, 1.20V} or {1.25, 1.20V}, and some OC'ing guide I'd encountered in the last couple days suggested that VCCIO could safely go as high as 1.25.

I can't speak for either Gigabyte board or the brand of your DDR4-3200 RAM.

On my Sabertooth Z170 S -- a mid-range of 12 phase-power-design and price -- and with G.SKILL TridentZ DDR4-3200 2x8GB 14-14-14-34 CR=2, I don't have to do anything with the VCCIO or VCCSA for error-free stability at 4.5, 4.6, or even 4.7 Ghz.

Some of the online guides suggest boosting VCCIO and then trimming it carefully if you're having trouble OC'ing RAM. Personally, since you can buy XMP memory at speeds I know of up to 3466 or thereabouts, there should be no need to try and squeeze more out of them.

Also, the indications I have are that you should never, never increase your RAM voltage above its XMP 1.35V spec, but I'm new to the Z170 chipset, and just getting familiar with the i7-6700K.

I MYSELF WOULD BE INTERESTED in the Ring or Cache voltage specs. I've seen a lot of folks don't want to mess with it. So the question is: how much can you improve the system by further tuning the cache speed and voltage? I thought I had seen where it didn't matter that much. If you know or think differently, I would like you to present your case for it so I can entertain a different view of things.

Like I said -- I'm new to 6700K and Z170 . . . .

I was looking for information on what is Ring Max seed in MHz and system agent Max speed in MHz of a Stock i7 6700k?

Sorry -- I misunderstood. Can I climb on this bandwagon and partake of the knowledge that may come along with someone else's replies?

Oh, hey. I'm sorry. I misread your initial question. Just a minute and let me boot up my own Skylake-in-progress and I'll report back. Somebody else might have the answer before I get back.

OK. I was using HWInfo64 for real-time monitoring, and summary report was unchecked. But the i7-6700K values you seek:

Ring Max 4,100
System Agent 1,000

Thanks!:smiley: I was wondering why clock for clock i7 6700k was so much faster than the i5 6600k at 4.2GHz overclocked, I can't change my ring max from 3500MHz or my system Agent 800MHz. Intel has me by the balls LOL, with a memory bottleneck to and from the CPU.

With your motherboard can you change Ring Max speed or System Agent speed?

I'm still learning about the chip and the chipset, so I feel unsure of myself. There is a setting in BIOS called FClk which can have values of 400 Mhz, 800 Mhz and 1Ghz. OC guides and info I've dredged up recommend setting it to 1Ghz. Whether or not you can do that, depends on your BIOS options.

And I could be confused myself as to whether Fclk and SA clock are the same. They certainly have the same values.

Nor would I know for sure the differences between the i5 and i7 processors in these matters with any precision.

I just read what you are asking. With XMP overclocking memory to 3200 speed the motherboard manufactures set the Vccio original 0.960v changed to approximately 1.165v Vccsa (System Agent) original 1.060v changed to approximately 1.275v

So from what I know talking to G.SKILL and motherboard manufactures increase the IMC voltage because the memory is running faster than stock 2133 speed, to make stronger channel communication with the IMC to carry the signal. So all you need to do is test your memory with pas mark memtest86 and if XMP setting works fine your done with those settings. If you want to reduce the voltage you can try that and test however I don't bother.

FClk is the PCI-E Bus don't mess with that it will crash your storage.
Vccio, Vccsa, Ring, is all memory controller (IMC)on the CPU.

Well one thing we know now with your help is the system memory controller is faster on the i7 6700k vs i5 6600k. The i7 6700k has Hyper thread also more Cache memory, also called CPU memory, is random access memory (RAM) that a computer microprocessor can access more quickly than it can access regular RAM. This memory is typically integrated directly with the CPU chip http://searchstorage.techtarget.com/definition/cache-memory

Do you have any other questions?
