Z370 / Z390 VRM Discussion Thread - Page 116

post #1151 of 1372
The Z370 segment is so confusing for me. There are now Taichi "sinopower" variants. The K6 and Extreme4 have apparent Load Line issues. The Gaming 7 is great but you might have a loose VRM heatsink.

What board is the go-to if you want good quality control, consistent parts (VRM), and don't want to worry about needing to "add parts" to the heatsink so the VRMs don't overheat?

Gigabyte Gaming 5 brother. VRM temps with turbo to 4.7 and all cores 4.3ghz stock settings with xmp profile for ddr4 3200 16-18-18 16gb dual kit, 30-40c idle in room with 20-21c ambient temps and 50-60c under full load in aida64 stress test and realbench so far.

Corsair spec 02 case with two 120mm front fans at 800rpm and 1 120mm fan rear 800rpm with dust covered open top and PSU facing up with fan which is a 140mm on an evga 850W B2. Stable so far. Using memtest 7.2 uefi boot to test ram yet system appears stable thus far.

Next overclocking time starting with a higher uncore. Stock on gigabyte for 8700k is 3.7ghz. On msi boards it's 4.4.

So I'll bench and compare numbers setting it at 4.4ghz since it should auto down clock with the CPU at set p states from windows 10.

Next it's CPU clock and voltages hoping for 5ghz around 1.36v - 1.4. (Got average 8700k silicon lottery because I got the worst luck, my 7700k is even worse!)

Probably the Infineon 35A DrMos suspected on the Z370 FTW. (Page 120 of manual) However the Z370 Micro seems to have an additional 4 pin power connector so I don't even know if the shot is applicable.
lots of compromises here, all fan headers are just 1a output...lagging behind than the average standard...
if this evga matx cant overclock well, it is totally suck.

I see, that's a bummer! Pricing of high-end parts in my country is also higher than the US so I'm used to buying stuff from the US.

Lol yeah, Asus can afford IR3555M for mid high range board, why Gigabyte cannot do that for top of the line OC board.
Even their X399/X299s have IR3556 which are only a bit glorified 3553s
post #1158 of 1372
If it is true Gigabyte used IR3553 instead of a 50A IR3556 or 60A IR3555, perhaps it is due to space constraints. At the same time I'm skeptical since SOC Force LN2 has multiple world records.

Buildzoid didn't get a picture of the board without heatsinks, so it could be inaccurate.

I guess the true 8 phase has lower switching delays than using the doublers as on APEX / Godlike.

This board probably won't be getting a monoblock due to low volume so it's literally a LN2 only board.

I have this same problem, I can not decide between GIGABYTE Z370 AORUS Gaming 5 (temperature/quality VRM?) / Asrock TAICHI z370 (audio problems? ), / GIGABYTE z370 gaming 7 (vrm temp) / ASrock extreme 4 - K6 (audio problems?) ASUS xtrix E ( vrm temp ).

ASROCK TAICHI vs GAMING 5 vs STRIX E vs ASUS PRIME Z370-A vs ASrock Extreme.

I think the taichi would be the most balanced but I have doubts because of its two variants -sinopower and a user in newegg mentioned audio problems, lately I have seen complaints about the audio on the asrock line - k6/extreme4 / taichi.
