Got a new 5960X from the tuning plan. 4.7Ghz on the core at 1.275v, 4.7ghz on the cache at 1.4v, might be able to lower it to 1.375v, needs more testing.

very nice, you've got to be happy with that!!

I've just made the jump to x99 from my trusty old 2500k because it was running flat out in some games at 1440p and I couldn't be happier with the 5820k. I was honestly expecting not to see much difference in games as my 2500k was running at 4.7GHz but it's a massive improvement and my system is running quieter and cooler.

Yep, huge improvement over my last chip which was an absolute stinker! 4.3Ghz needed almost 1.4v.

Can you run cinebench for me please at 4ghz?

No worries :)

Anyone know anything about the LGA-2017-A Asus x99-e ws motherboard? Only x99 board to support upcoming Skylake cpu's? Seems it is a workstation board so i'm guessing it would be expensive for compatible ram and stuff?

Does skylake not support x99 then?

Different socket i think, but that board i mentioned is apparently made to support Skylake as well.

So others would need a new board for Skylake, would you expect any less from Intel? :p

Link here : http://news.softpedia.com/news/ASUS...Motherboard-with-Skylake-Support-458632.shtml

"it has six extra pins, which allow it to accept Haswell-EP Xeon CPUs as well. More importantly, it will supposedly let the mainboard accept Intel Skylake CPUs. The ones set for July 2015 release.

According to a source that will remain anonymous, the socket is called LGA 2017-A, unofficially at least. In essence, this all means that the motherboard won't become obsolete in 9 months (when Broadwell gets replaced by Skylake). Instead, it should be good for 18 months to 2 years."

Right. Been messing with this offset voltage business to get idle temps down without sacrificing any load temps or performance. (5820k, X99 Deluxe). I am using 125 strap which is very important. I believe the processor has a VID/multiplier table built in that it uses to request voltages as it ramps up and down. These multipliers assume 100 straps though so the 36 multi assumes 3.6GHz not 4.5GHz. By that logic I know I'm going to need a +ve offset to keep it happy and make up for the 25% increase in clock.

Goals

4.5GHz @ 1.27V @ 100% load (my previous result with fixed clock)
As low as possible frequency/voltage at idle
Stable

Approach

Step 1. Go back to a low multiplier. I chose 125 x 28 (3.5GHz).

Step 2. Enable Enhanced C States (not C4 or C6 until i read up what they are).

Step 3. Switch voltage to offset from fixed. I figured I'd try my luck at +0.2V.

Unfortunately this crashed as soon as I loaded realbench so I upped the offset to +0.3V. This then gave a voltage low of 1.032V @ 1.5GHz and a high of 1.212V @ 3.5GHz. Stability was fine as this is a hefty voltage for this clock speed.

Step 4. I dialled up the multiplier a few increments at a time as I didn't know the value I was offsetting from and didn't want to end up putting 1.4V+ into the CPU by mistake. I now know a few values from my VID table by working backward (i assume these are cpu specific?):

Multi / VID
12 / 0.825V
28 / 0.9V
32 / 0.98V
34 / 1.012V
36 / 1.048V

So at 125 x 36 I was putting in 1.348V which is far higher than I knew the chip needed.

Step 5. Dial the offset voltage down. I eventually settled on +0.235V which gives 1.283V peak and 1.271V @ 100% load due to vdroop with LLC7 enabled.

TL;DR

Offset voltage of +0.235V instead of fixed 1.27V allows me to maintain all the power saving features and the healthy overclock (125 x 36 = 4.5GHz). Idle power draw has reduced from >50W to <25W, it's cooler and quieter and cheaper to run :)
 
This is my first Gigabyte board since my X58 UD4 and the bios is the biggest POS. So disgusted with this board. The beta bios i had installed failed so the dual bios flashed the old bios back thankfully. Should have bought an OC Formula like i had planned. Done with you Gigabyte

Bah Humbug - you've got a better chip than mine - swine !!! Lol :p
No not really - glad you got a good un this time round Matt.

Thanks Mark. Knowing i have a good chip makes me want to nurture it and take care of it. The last chip i had was a hussy so i treated it mean. :D
