[UPDATED] Der8auer States Some X299 Low End boards Have Bad VRM Coolers

Well, it seems der8auer has had issues with the VRM coolers and single 8 pin connectors on X299 boards. In this video, he shows the VRMs get up to 100°C on the board, as he estimates the VRM modules themselves are probably at TJunction max, and the single 8 pin connectors on PSUs can hit 60°C when overclocking the 10 core models, oops.

 

He blames the manufacturers and Intel, which might be fair, since the launch was moved forward, so watch out if picking an X299 board folks. This probably won't be so much of an issue for normal users with 6 and 8 core units, but if you buy the 10 core chip and clock it to 4.5GHz, there is a chance the cooler on the VRM and power connector might overheat, that really isn't good for high end stuff

Does this issue effect all of the cpus or only the higher core ones that are overclocked, i have a skylake x will this effect me in any way?

Throwing 4 dies on one PCB and making the chip the size of pluto, not rushed at all! 

And how does having a scalable architecture where you make all cpus from 1 base die, thus having huge yields and making a large profit at a lower price to the consumer make it rushed? That sounds like a design rather than rushed.

It's the VRMs so all

using more than 1 die isn't rushed at all, in fact it should mean they can pick the best 8 core dies they have and put that on the package instead. It looks like on Thread Ripper at least, half of the cores will be disabled if they go with 4 dies, meaning you really will be getting the best, I'd say only EPYC has the full 4 dies though, no point in wasting dies, 

TR is two dies

having more dies with disabled cores suck because infinity fabric is great but it's not godlike

Hey link me the Threadripper review you are referring to.

does Lisa Su at a conference count as a review?

also I don't think I was referring to any reviews =/

Only the higher core count ones with the lower end boards, I should edit the post to make that clearer, the 6 core chips and to a certain extent the 8 core one should be fine when moderately overclocked and no extended test is used. What board did you buy?

This isn't a 7640X. Kabylake-X doesn't have 2 substrates. This is a 7900X

That makes even less sense. Why the double substrate? Intel STAHP!

No the 7740 and 7640 also have the 2nd subtraight, google it. All LGA2066 have the two substraight package construction. 

edit: although you are right, the kaby Lake X dies are the same size as normal ones, so this isn't a kaby lake X chip

It's easier, because they can use the same substrate for Xeons and Skylake-X CPUs. AMD does the same thing, but instead of using the same substrate, they use the same die

Watch the video smarty pants. Only Skylake-X has 2 substrates

Odd, I seen an earlier one that had a tiny die on the same 2nd package, maybe that was an engineering sample one. It still sucks these aren't indium soldered.

Havent bought any board yet just waiting but i have to get a ATX one

if you have the 6 core chips than sorta any board will be fine, but I'd advise one with an 8+4 or 8+8 power pin and good VRM heatsink just because.

Which one has the 8+4/8+8?

Just get one with a good cooler on the VRM.  The VRM itself isn't the issue.  It's the poor coolers attached to the VRM on the cheaper x299 boards that's allowing the VRM to get too hot.  Find one that uses a quality single heatsink or a dual heatsink setup joined via a heatpipe and you'll be just fine.

 

I'm putting a ridiculous amount of power through mine while testing Cinebench R15 performance at 4.9 GHz on a 7900X 10 core.  I'm talking 500w at the wall for CPU and system draw and my VRM doesn't even get really warm and there damn sure isn't any throttling. 

 

You're going to love how strong these cores are on Skylake-X.

 

Right now I'm at 220cb for single core and 2763cb for multi.

EVGA has 2, of example.  The "Black" and the "FTW-K" versions have 2 x 8.

So which ones have a good heatsink?

ASUS Prime X299-Deluxe, ASUS PRIME X299-A,  ASUS TUF X299 MARK I, ASUS TUF X299 MARK 2, GIGABYTE AORUS X299 AORUS Gaming 7, GIGABYTE AORUS X299 AORUS Gaming 9,, MSI X299 GAMING PRO CARBON AC, MSI X299 GAMING M7 ACK.

All of those boards have more than 1 power connector for the CPU. I'm not sure which is the best. This isn't a complete list either, just the page of Newegg US's online store

Wait, you managed to get 4.9 Jigahertz? How many volts did that require?

Man, you're going to have to do a bit of research.  The dual heatsink design with a heatpipe is optimal.  If you find one that only has one heatsink, then research it and make sure it's up to the task.

 

Most of the cheaper boards will not have good heatsinks.  This is no different then any other platform.  Hell, my son's z170 board throttles 7700K CPUs with high clocks unless you put a fan on the VRM.  It has a cheap cooling design on the VRM.

There arent really "Cheap" boards with x299 though they are all pretty much 250+ usd

I'm still down on the whole LGA 2066 platform, it's too expensive. I'm quite happy with a room full of dual xeon servers for serious work and my i7 7700k PC for playing. For not that much more I could build a rack server with two 10 core CPUs and utterly crush the performance of the 18 core CPU's, they don't entirely make that much sense at this price.
