Pro Overclocker der8auer calls Intel X299 a "VRM Disaster"

Which board are you testing Tom?

I also notice you have the board in a case with fans above it drawing/sucking. Any airflow at all improves the situation as he pointed out. It was similar with my old Asrock 4+1. No fan, throttle, add a fan blowing over the VRM cooler I could overclock.

Any way, what concerns me more (and why I was laughing) is 300w through the 8 pin. That is woefully short of power. If you think back to the days of X58 and 24 pins literally melting because the GPUs were drawing too much power through the board (dual 5970 or tri sli 480s as an example) then I would see that as far more dangerous. Drawing 300w through 4 quite thin wires is outright dangerous and why his cables got hot. One tiny spike and you have a fire on your hands.

And THAT is the problem when you make motherboards for a platform that is all over the bloody place. Quad cores, 10 cores, 18 cores... That's pretty bloody stupid.

It was the same story on Bulldozer and Piledriver. Companies (laughs at MSI, whose boards caught fire) were making 4+1 boards with no VRM cooling whatsoever and they were burning up. Why? because AMD decided to release their BD CPUs on a single socket so you could go from 2 cores all the way to 8 and the boards were mostly the same.

So now not only do you need to find a board for your X299 CPU you also need to find an appropriate board.

Which let's face it is quite complicated and tricky. Especially since mobo manus do not outright tell you how many phases a board has and whether it's suitable. They don't tell you anything of the sort unless they are boasting about it so the only way to usually find out is to take off the sinks and count the fets.

That's madness. Utter, utter madness.

Also, who is going to brag about their fets when they are crap? look at the MSI 370 Tit board. 6 phases. Can't see MSI bragging about that, especially on such an expensive board.
 
Ive tried the X299-A - Gigabyte Gaming 7 and MSI Carbon today....

If an overclocker isnt cooling other parts of the board in an open test bench its not the boards fault

Also I dont think my normal airflow from a case would slash 30c off of temps, I think there is a bit more to it tbh.

That's what i think Tom... not 30C...
AMD is paying someone imo since that guy (a famous overclocker) should know better if this was in fact a PSU issue.

I dont for a second think this is a paid troll and he will have achieved those temps. The questions should be how and why - I dont think in all honesty the boards are as bad as he is making out or IF they are its in a very limited configuration that didnt really require all the hype.

At least I know what people will be trying to post on every X299 motherboard review though.

I heard that he has a high leakage ES CPU. He's also questioning his PSU...

It will all depend on power draw on actual retail samples. I still don't think it's a good idea to run a single 8 pin into an overclocked 10 core CPU, though. That will be very risky.

This is what you get though when you release two or three separate platforms onto one motherboard.
 
I agree with that tom said that being "well it's going to be in a case and have fans blowing at it"
Problem is, shouldn't the heatsinks looks a bit more heatsink-y ? Der8auer is right on that thing "I don't know if they are heatsinks or thermal insulators" Putting a slab of metal on the vrms and calling it a heatsink (giving it 5mm of "fins") doesn't cut it.


I know that efficiency has come a long way but we are talking big chips that have a tonne of cores and a great amount of current to run. Take a look at the x58 TuF, the crosshair IV extreme, or the X99 WS from asus (something modern), beeing a motherboard manufacturer and thinking "hey there are going to be fans around the vrms so it's fine" it's a bit half-arsed isn't it? Especially if you are paying that amount of money, you want everything to be perfect


That all if that's the case, if it is indeed his PSU then he's made a half arsed "Experiment" lol

Ive done all of mine with a single 8 - adding more got me nothing but more cable mess tbh. Made no difference to the PSU what so ever
 
Thanks Tom for your investigation and sharing your ideas in this and the original thread. I'll make some links in other fora to yours.
 
You went off on a huge tangent....

Mine are not getting that hot. Warmer than X99 sure, but its drawing more power so it will.

I think if you get a 10C cpu youll get a decent motherboard if you want to overclock anyways

The video is about temps and insufficient VRMs and cooling. Like how some boards only have a single 8 pin, yet the wires get hot running a 10c OC.
 
Tom, any chance of you making a video with your testing and results and thoughts (or maybe incorporating it into an upcoming video) or would you rather keep it to the forums and stay away from doing such videos (which would be understandable)?

Right. His wires are getting hot because tbh the PSU design isnt that great. That could also be cause the fet issue

Ive only run a single 8pin and its be absolutely fine - adding in a second made no difference to temps or clocks. My wires never got hot and Ive checked too.

Get off the hype train - Ive looked - Ive tested - Im expecting him to make some kind of statement about his kit and/or testing

Strix X299 review - its next and its in there. (ive delayed the review to go back test and include it)
 
So, as Tom knows, I tested this same PSU with a 300W load on a single EPS12V connector.

Temperatures of the connector pins never got near 40°C. Voltage only dropped .22V despite having only three 20 AWG wires going to a four pin EPS12V. With that said, I go back on what I said and will say that I would GLADLY use this PSU's, or any decent PSU's, EPS12V connector to push 300W of power.

I don't doubt the guy believes his results... but something is wrong with either a piece of his kit or his thermometer.

This explains a lot to me I have never heard anything negative about a Superflower PSU and I must say it had me questioning his video. I own a Leadex 750W and trust it fully.

Well... Not every Super Flower is perfect and this PSU still has negatives. Three 20g wires split into four isn't a great design. All I'm saying is it doesn't contribute to anything this guy is reporting in his video.
