the link there shows only the difference between the bridges and 2.0 and 3.0. not 8x/8x and 16x/16x

but yea I'd need a 5830k at least you are right....

I feel like I'm taking crazy pills here.

Has nobody else noticed these things work with multiples of 7? It occurred to me while staring at a page of voltage sets I've written down how close many of my numbers were to divisibility by 7, so I went full DaVinci code and wrote a list of them out in ranges near my voltages.

7 x 256 = 1792, which is my exact stock VCCIN voltage in millivolts.
7 x 162 = 1134, which is my exact stock 39x core VID
7 x 172 = 1204, exact stock 39x cache VID
7 x 144 = 1008, stock IOD

Scaling VCCIN in 56mv chunks popped out a few I've previously seen islands of stability around like 2.044v and 1.736v. I randomly pulled 1.680v off the list and it turns out my CPU plays just fine with the correct low VCCIN.

Doing some low multi testing, I noticed that cstkl1 was spot on. My CPU runs 41x core stably in prime95 blend at its 39x VID, and testing in 14mv steps proved 42x stable 42mv later. Following the pattern matches previous experiments' required voltages with 43x 1218mv, 44x at 1260mv, and 45x at 1302mv. 46x would be 1344mv if linear scaling holds true, but considering it tends to break down around the 1.3v mark and mine scales poorly from 1.05v on, I'm probably right on the mark rooting around at 1.35-1.36v.

Because 2.0 16x is the same speed as 3.0 8x it's often used interchangeably.

Hi guys, i've been running a 4690K + MSI Z97s Krait motherboard with 2400Mhz ram for a few months now but i've been using the stock cooler (boo!)

I finally got my water loop set up (1x120 rad and 1x240 rad, and I've started some proper overclocking on my chip and from what I can tell, I haven't done well in the Silicon Lotto frown.gif

I can get to 4.7Ghz but to keep it stable i'm running 1.38V. Temps are fine, idle is at around 33C and its topping out using CPUZs stress test (100% multicore load) after 4 hours at 58C.

I would like to get to 5Ghz but i'm expecting to have to dump a lot more voltage into this to get there which I don't want to do, as it would do 4.5Ghz stable at 1.280V and I'm expecting to need 1.45V+ to get to 4.9Ghz

any thoughts what I could do to get it stable without massive leaps in voltage?

U can try lowering uncore and maybe RAM speed to exclude other possible sources of instability, but if everything else is set up right more voltage might be the only way.

what would be deemed the absolute safe limit voltage wise for a 4690K with a custom water loop?

I dont really want to go much past 1.45 if I can help it.

Nobody knows exactly. Chance of chip degeneration probably also depends on each individual chip anyway, just like voltage requirements. In general for 24h, 1.4v is often the recommended max.

I thought that might be the case.

I will try for a 4.8Ghz at 1.4V and see how stable it is, but i'm thinking its going to be a 1.415V or more to get stable.
