Overclocking

Default Clocks

racing cpu-z

Again we see, the default clock on the Ryzen 7 3700X is 3500MHz. It seemed to down clock from the normal default of 3600. A lot of the Ryzen 3xxx chips run at this base clock. Now let’s see what we can get this chip up to on this motherboard.

racing cinebench stock

As we can see from the above Cinebench R23 picture, at the stock clock of 3.6 GHz we were able to score 13018. It boosted up to 4.242 GHz on all of the cores. Not too bad for being at the stock clock.

Next, we decided to manually overclock this chip and voltage. We figured we would start by trying an achievable 4.4 GHz. Unfortunately, it would not boot at this clock speed. We tossed 1.45 volts at the CPU and it still wouldn’t boot.

What I was able to achieve with this board, was 4.3GHz. I tried 4.35 and no matter what I tried, it would not boot and/or be stable at anything more than 4300 even.

racing cinebench 4.3

At the best we could do, 4.3GHz, we received a Cinebench score of 13,357 which was close to 400 points below the recently reviewed MSI B550 GAMING EDGE WIFI.

Was the lack of a better overclock due to the phases or cooling on the MOSFETS? Without BIOSTAR “bragging” about their cooling, one can only guess.

Keeping VRM’s Cool

Keeping VRMs cool in any enthusiast’s motherboard is an important aspect of how well an overclock will hold up and how well the system will run. The BIOSTAR RACING B550GTA Ver 5.0 seems to have an adequate cooler over the VRM’s, however, not knowing what type of heatsink or what thermal pads they used, only leaves all of us to guess how adequate the cooling really is. With an overclock of 4.3GHz when we have seen over 4.4 on the other two boards I’ve reviewed, leaves a big question in my mind. At the current price point of $159.99 I would think that they would have boasted about the VRM cooling and the overclocking capacity of a board with a “RACING” brand.

  1. Very nice review, also nice seeing BioStar covered. I have yet to be disappointed with them.

    I bought an Open Box BioStar B550GTA from NewEgg, awaiting for delivery. Somehow I thought the last slot was a 3rd pcie slot, turns out to be a pci slot which is most likely I will never use (I usually end up using every slot on a board or close to it). I have a BioStar B350GT3, bought very early with the Ryzen 1 launch, what a stable motherboard, problem free, what was so odd at the time with that motherboard was it was able to run Hynix ram @ 3200mhz with 1.45v (virtually all boards at the time were 2933mhz or less if you were lucky even with B-Die ram). Except I broke the first slot pcie x16 slot lock plus worn out the socket -> Time for a new board.

    Will be using a Ryzen 3900x, will see if 4 dims also work for 32gb of ram with the 5700 XT AE.

  2. Commenced testing system, I normally do this outside the case for ease of motherboard testing, B550GTA, Ryzen 3900x, 32gb of ram here. Here it is CPU, Cooler, Ram and video card. Goal is to maximize memory speed by using a self bootable form of MemTest86 using a USB flash drive. 4 dims, 32gb, passing 3200mhz XMP profile, Vram 1.37v, Soc set to 1.1v, had to set ProcODT to 36.9ohms (XMP without that would not post).

    Cooler clearance was very tight and is slightly pushing on the dim closest to the CPU. This is actually the first AMD motherboard that this CPU cooler would fit with first dim slot used. Biostar B350GTA and ASUS CrossHair VI Hero cooler did not allow first dim slot to be used.

    Once I get the memory tested and maximize initial speed for the ram, I will install the M2’s/SSDs and eventually an operating system. So far all slots filled and 3200mhz Cas 14 memory passed without issue, currently testing at 3600mhz.

  3. We are trying to ensure we get a little variety on the brand front.

    That is good.

    Well the motherboard tested good for 3600mhz ram timings, 16,16,16,16,36 with all 4 slots filled. 1:1 ratio. 3733mhz also tested good, installed SSDs and installed Win 10 Pro and found that it was 2:1 ratio so have to redo 3733mhz testing. Current ram Aida64 benchmark. Will optimize timings further and speed. ZenTimings indicate VDim is 1.2v but actually is 1.4v in the bios. HwInfo or Aida64 does not read the voltage of the Dim at all.

    Installed WiFi card, loaded latest bios, so far all is working good, still more testing needed. Deciding which case it will get to be installed in, have several spare empty ones laying around.
