mtruchado Hi

Thanks for sharing your experience with the x470gt8. For me the killing feature of that board is to be able to use your "old" cooling system (I have a zalman reserator 3 MAX), this is saving me some money I can spend in other parts, and if this thing can cool my old FX cpu, I'm sure It can cool whatever ryzen I put on It because Ryzen is more power efficient (my FX consumes 125W).

Apart from that, I have here a 3200Mhz kit from Ballistix (crucial - micron), and It's nice to read that I could be able to run It at almost max speed... when using two of them. I really doubt I can get the 3200Mhz when running four of them, although mines are single rank (usually provides better result), let's see as I have them and I have no motherboard where to try them.

The hardware is impressive, It's even an intel NIC included, really hard to see nowadays where everyone install these cheap realtek solutions. Here I can find It for 177€ (I'm living in Europe, alternate has It at that price), I want to give It a try...

Nighthog Biostar have announced PCIE GEN4 support for their B450/X470 boards.

https://www.techpowerup.com/257515/b...s-motherboards

Just perfect that a BIOS comes out the day after I rebuilt my PC with another board and a Ryzen 3800X.

The new BIOS is X47AG718 with AGESA ComboAM4 PI1.0.0.3AB (beta)

I still have my Ryzen 1700 @ Biostar board around but no memory to test this it out with(MEM in the main system), I'm completely occupied into the new board and it's features for now. Though it would be fun to test the 3rd gen Ryzen on the board as well at some time I fancy.

The same memory could boot 4000Mhz+ @ 1.200V on the 3800X and X570 motherboard that only barely did 3200Mhz on this Biostar X470GT8. 3333Mhz wasn't stable in the end.

Nighthog New BIOS again with AGESA Combo-AM4 1.0.0.1 X470G523.BST

I found no new features in the BIOS but seems MEMORY support has been improved.

Can now for a easy test actually boot 3333Mhz for a beginning and run TestMem5 without unsurmountable errors right away. Seems you can actually run this now. Though it's manual tuning, most auto settings aren't actually really that usable for stability.
Will be slowly working my way up to better results as I find the settings that it likes for best stability.

A bonus is lower ProcODT values seem to boot this time around and are better for memory stability.

miklkit Woot! New bios is out for the X370 GT7 and X470 GT8. It will hopefully give compatibility with Zen2.

miklkit I'm running the X370 GT7 and got my 3200 cl16 ram to 3030mhz.


Nighthog is running the X470 GT8 and got his 3200 cl14 ram to 3200.


Both of us are using 1700 cpus. Memory compatibility is the weak spot on these boards and I'm waiting to see how the X570 version works out.

Cosminnn Any X470 alternative? With the same VRM capabilities and better DRAM overclocking possibilities? I am looking at the board to suit a Ryzen 5 2600, even thou 3200 MHz is a good value from me, not the best, but OK, for G.Skill - Flare X Series 16 GB (2 x 8 GB) DDR4-3200 with 14-14-14-34 on plan.
Keep it into 170-180 EUR value.

miklkit That is why I stopped at 3.925ghz @ 1.356v on my 1700. It just wasn't worth it to go higher. The highest vrm temps I have seen was 68C on a hot day with the usual being 62C. In normal use they sit in the 36-42C range.

My 990FX Sabertooth pushing an FX @ 1.51v would have the VRMs go over 81C if the stress test was left running long enough. I had an air scoop taking some air from a front case fan and directing it behind the board with exhaust slots cut into the back.

Really winning the silicon lottery on this one. (it' great!) /sarc

Oddly enough I haven't really noticed "degradation" per see but time will tell. Gonna be picking up a Ryzen 3xxx series soon enough.
I've pushed 1.400V SoC on my gigabyte to it as well for 3800Mhz memory runs, why I picked up this Biostar with it's 4-phase SoC to be able to push even more voltage but sadly this board won't boot above 3200Mhz MEM as mentioned earlier making that VRM for SoC useless in practice.

On the other hand I'm impressed the VRM didn't reach 80C at all either. Stayed 77C as max with several runs and I don't have a direct airflow on the VRM heatsinks either. Just passive/cross-flow from radiator fans in the chassis.
Room temperature was ~20C I reckon at average if not colder (window open with below 10C outside)

I've been eyeing another WC CPU block but wonder if it's just wasted money in the end, this CPU sample is at it's limits either way.

Nighthog Finally about settled what this Combo will do stable.

Be aware I have a launch day Ryzen 7 1700, they aren't as great as they later ones. Voltage is in danger zone

Was a hassle to nail out the last bit of stability with memory errors but found it in the VDDP voltage to finally settle it. (it mostly affects how low you can go for tRAS & tRC)
Prime95 will overheat with this voltage, my cpu waterblock isn't good enough. (Alphacool NexXxoS XP3 light V.2)
