Intel X299 (Socket 2066) VRM thread

Hello

In regards to Additional Turbo Mode CPU Core Voltage yes. Going back to the voltage values you posted and doing the math you will arrive at the same conclusion as well as the approximate value of the default core voltage. The word "Additional" in the Turbo field is very descriptive in this instance.

You were right. I set the BIOS field back to auto and it stayed the same value when checking elsewhere. Thanks for the advice.

I found the picture of the back of the Gigabyte X299 UD4 VRM and X299 Ultra Gaming on Newegg

So question? MSI Xpower vs waiting till August for the Asus rampage extreme?

Thoughts......

Wait for reviews.

It comes down to the heatsinks and board design at this point.

Nice, so most likely it's a IR35201 running in 7+1 mode for both while the powIRstage for the VCCSA is a IR3553.
The only thing we need to guess about now are the powIRstages for VCCIN but I'd expect them to be IR3556 parts too.

Got an MSI X299 Xpower Gaming AC board but only had time to take some quick pictures so far. 1x 8-pin + 1x 4-pin. Not looking great, most plastic board yet.


VRM heatsink, plastic cover on top restricting heat dissipation. Most likely 12+1 phase configuration (6x2+1). Best guess for power stage would be IR3555.




Back of the VRM heatsink. Very thin bottom metal plate contacting to the heatpipe.




The heatsink by the I/O cover which connects to the heatpipe. Half of it is covered by the plastic I/O cover which really limits how much heat it can dissipate.




6x doubler ICs. No backplate.

IR3598 or IR3599 doublers? Will you pull of the heatsink later on?

Yes, hopefully this week.

Edit: IR3599, doublers without drivers.

Anyone here have experience with how ASRock's OC Formula series boards tend to compare to ASUS' "Extreme" and "Apex" series? The VRM cooling and design on the Apex looks wonderful, but the board won't fit in my case. I'm skeptical of ASRock because they were traditionally a "budget" brand, but they seem to have genuine high-end offerings now - and the Z77 Extreme4 I've had for several years is still going strong, so I guess the skepticism may be unwarranted.
