[ASRock] - ASRock X299 Taichi XE + X299 Professional Gaming i9 XE introduced - Page 8

post #71 of 109
Currently have the Fatality i9 XE for testing, along with an Asus Rampage and Apex. Looking for the best board for OC on the 7980 18-core beast, and will be checking temps on these boards with an AIO cooler and case fans.

Already, I'm baffled by a few of Asus' choices. Whereas the Asrock XE boards give you 128gb and 8+8 power, Asus put a 128gb limit on the flagship Rampage, yet it only has 8+4 power. The Apex has 8+8 power, but is limited to 64 gb ram. Ostensibly this was for overclocking purposes, but most are saying the memory overclocks easily, even on Rampage. It isn't a X399 situation where anything above 3000 was rare as a dodo.

Just setting up the Fatality XE today after a successful (it posts, so?) delid of the 7980XE last night. That Conductonaut liquid metal is a major PITA, but I managed to keep it off the delicate parts.

Updated soon!

Is the mounting holes for the OCF / Taichi XE the same? The latter might have a slightly bigger heatsink it seems.

Thank you for this. Currently deciding between the rampage extreme and fatal1ty ex. Please keep us posted.

Only had a chance for a quick set up of the Fatality XE tonight, but I like what I saw overall:


- no VRM temperature issues at a 45x multiplier and rest on defaults, even when HWINFO showed CPU draw of over 500 watts
- I need to verify I have the right sensors, but VRM temps appear to only change by 25 degrees, or the high 50's.

- several back to back Cinebench runs produced scores consistently in the 4200-4300 range.

BUT...

- HWINFO showed that several times, the CPU thermal throttling was tripped, with temps listed at 102C.


I'm not going to fret too much about these results yet, because the cooling situation when this was run was very poor. No case fans were active, and the case was set on its side, with only the Kraken 62 providing cooling. And even then, it appears there was no ramping up of pump or fan speed to counter the temps. Very strange.

As a side note, is it really unusual to have an AIO cooler with separate 4-pin connectors for the pump and the fan array? Virtually every one that I have tried ether ties them all into one connector, or has the fans plug into the rad (Fractal Design units). I really liked the way Enermax made their Liqtech TR4 360, probably the best non-custom cooling solution for Threadripper. There were separate fan and pump wires that you could plug into CPU FAN and CPU OPT, depending how you wanted things to go.

Granted, I'm not sure how much flexibility we lose with the one wire arrangement, but I did like the ability to change pump and fan settings separately.

did you get your 7980XE from SL or retailer?

I guess same info as Taichi XE.

Retailer, Newegg a few weeks before the boards started being stocked again.

Yep, delidded. I love how it corrects that to "deluded". Perhaps? smile.gif. I was a little nervous working on a $2000 CPU with the liquid metal stuff, so practiced on a few old chips. It has a certain way of interacting with metal that's very different from standard paste, and could lead to using too much at first.

I filled the Corsair 740 with fans, and a Fractal Design Celsius S36 as the AIO mounted in front. Going to set up just a standard front to back, bottom to top flow, and see what happens.

First step will be to drop in the Asus and Asrock boards and test them at BIOS defaults, mainly temps and VRM loads!

What I don't really like about the newer ASRock boards is their wifi speeds hat's capped to 433 mbps unlike the standard 867 mbps. I guess the difference between the Taichi XE and the Pro Gaming i9 XE is one has 10Gb port.

Just did a quick face off between two boards, the Asus Rampage 6 Extreme (R6E) and the Asrock Fatality XE (FXE). I was mainly looking at "out of the box" extreme conditions with an 18-core 7980XE chip pushed to 44x multiplier.

Both boards were set to "Sync Core / All Core" multiplier of 44, and multiplier shifts of -3 for AVX and AVX512.

On the Asus board, voltages were set to .001 adaptive in all fields. On the Asrock, I left voltages at Auto.

All hardware was ported over to be exactly the same:

EVGA 1600 Watt PSU
128 GB Gskill RAM
Samsung 960 Pro 1 TB SSD
Fractal Design S36 360 AIO cooler
Corsair Air 740 Case (Note: Asus board allowed for 5 case fan power, Asrock only allowed for 3, so I disabled bottom two fans, farthest from the heat)

7980XE CPU delidded with Rocket 99 tool and Conductinaut liquid metal applied

Results:

The R6E maintained an idle CPU temp of 28-32C, and the FXE was 8-10 degrees cooler at 13-16C. Under no load whatsoever, this could be due to calibration of thermometery or slight differences in surface airflow on the boards.

Both boards easily completed Cinebench runs with scores in the 4300 range, utilizing all 18 cores at full capacity. CPU temps bolted to 73C on the Asus, and 65C on the Asrock, and there was no thermal throttling of CPU or VRM.

A different story emerged with the Prime 95 run. with maximal heat settings. Very quickly, both boards were pulling nearly 400 watts from the wall, and both began the Prime95 chugging along at a 41 x multiplier. (Remember that Prime95 has AVX on, and I had set the offset to -3). After about 10 minutes however, I began observing an oscillation in the HDINFO multipliers on the R6E. I scrolled down to see that none of the CPU thermal flags were tripped, and CPU temps were still around 70+C. Then I noticed that VRM temps (via the Asus EC sensor in HDINFO) were at 109C, which is near the listed amount for VRM throttling to begin. Touching the Asus board, the heatsink was uncomfortably hot to the touch, along with the heat pipe extending around. I had left the shroud on per stock config, and noticed very little heat transfer to the exposed metal.

Running the same test on the FXE produced mid-60C temps in the Prime95 run, but the VRM's never throttled. All cores remained at 41x with temps stable and no thermal flags tripped in HDINFO for 60 minutes. The heat sink on the FXE board was hot, but noticeably not as hot as the Asus board. Also, the heat pipe and IO heatsink on the FXE were warm, with the IO heatsink warmer than the R6E, and the heat pipe cooler. Overall, it seemed like the FXE was moving the heat around the back of the board slightly better than the R6E.

Conclusion: Out of the box, using AIO cooler and stock fans, the Asrock FXE will hold a 7980X at 41x AVX, when an R6E will not. For whatever reason, the VRM/heatsink system on the Asrock FXE is superior to the R6E. The FXE also has 8+8 power, versus the R6E 8+4. That isn't to suggest things couldn't be improved by the addition of a fan onto the Asus board, but I was just testing stock for grins.

I'll be deciding which way to go in the next few days. Despite the advantages, the Asrock board has some quirks I don't like.
