HeyItsChris

I took some more pics including the damaging of the case to fit the larger than typical ATX power supply, the Dell Precision T7500 1,100W PSU. It's an amazing power supply for the money providing very solid 12v rail capabilities & 16 AWG thick wires ensure stability, continuously under load. I know it's an eye soar but later on I'll take it to a shop & have them cut out the metal & weld a brace to reinforce the chassis. So far I'm waiting on my 12" Molex Extension for my PCIe x1 USB 3.0 adapter with front panel 3.0 header & my 12" 24-pin power supply EPS power extension for the short 24-pin on the Dell Precision T7500 or it's only because the motherboards power connectors are at the very top & the PSU is at the very bottom of a standard ATX case so it just can't quite reach.

To be perfectly honest I plan on using it to light a cigarette. I already created a coil wire & connected it to the 5v & ground on a molex connector on a psu & it works just fine. Just turn it on for 2 seconds & its lit & turn it off & its all good. I just wanted a smaller simpler psu that provides only 5v so I can connect the positive & negative to the leads then connect a 2-prong ac power outlet wires with 2 wires to the 5v power supply. All I would do is plug it in for 2 seconds, light the cigarette & unplug it. Do I need to buy a 3-prong ac power cable instead with positive, negative, and earth ground? As you stated, I'm guessing the answer is absolutely yes. Thanks again

@ArchStantonSo is that earth ground required to get power to the device? It won't be operating continuously, only a few seconds at a time. Thanks

Nice yeah the 3550h vega 8 had a clock of 1200mhz but the 2500u is 1100mhz. By the way cool mod bro! I wanna buy your laptop model & do the same mod! Whats the exact model number? Here are my results comparing the RX 550 at 1250mhz core & 1375mhz (not much so ill leave it under volted and at 1250mhz for safety purposes). Against my 3550h mini pc & my 2500u laptop. Looks like the Ryzen chips surpass the Opteron 4386 on the CPU test. Result WWW.3DMARK.COM This one I overclocked the RX 550 to 1400mhz core & this is the result. 3dmark.com WWW.3DMARK.COM

Interesting. Yeah my eGlobal AMD Ryzen 5 3550H Mini PC has Vega 8 GFX as well & its way faster than my HP ENVY X360 AMD Ryzen 5 2500U. My eGlobal AMD Ryzen 5 3550H Mini PC has an unlocked BIOS so you can tweak the memory speed & timings. I run DDR4-2933 on the AMD Ryzen 5 3550H with 3200mhz module's. Not to mention they replaced the motherboard & put in a T-Bao motherboard with unlocked TDP settings in the BIOS so I set it to 54W & added a copper shim to the Core Diode to cool it down at 54W TDP. It performs amazing now. It holds 1200Mhz core on the GPU Vega 8 & 3.7Ghz on the AMD Ryzen 5 3550H. Which smokes the AMD Opteron 4386 on Cinebench R15. It scores almost 800 points on Cinebench R15, while the 4386 scores 511 points. I'm happy with the performance of the 4386 though it's amazing & cool running too only 48°C max temp. Can you post pictures of your modded heatsink on your Acer Aspire with the Acer Nitro heatsink? That's really cool.

In my opinion though I think this RX 550 BIOS modded smoked the Vega 8 graphics which would throttle the gpu core clock all day well below 1100mhz peak, down in the 600-700mhz range with only 8 ROPs, it was pushing 4.8GPixel/s or so maybe a little more & the RX 550 @ 1250mhz core pushes a solid throttle-free 20GPixel/s with 16 ROPs. Plus I overclocked the GDDR5 from 1500mhz 96GB/s to 1875mhz 120GB/s & added super-tight memory timings to the BIOS. It appears to run much much faster than the AMD Radeon Vega 8 gfx but I will test it & compare & post the results. Thanks for your amazing advice though buddy! I love these Forums & this Community a lot. Even as much as Overclock.net which I been a member on for years & years.

Here is some benchmark data of my new AMD Opteron 4386 8-core up to 3.8Ghz, which beats out my AMD Ryzen 5 2500U which is great. The Dell OEM Low Profile AMD Radeon RX 550 4GB under-volted down to 950mV & 1250mhz core 1875mhz memory with 75w tdp & reduced hot spot down to 84°C from 105°C. Only 5 fps less than 1375mhz core with 105°C. It also runs 20°C cooler at 950mV from 1050mV but set to 1075mV via stock vga bios.

How do I force the cpu into it's max multiplier all the time? I hate this that it only goes up to 3.3ghz under full load, the 4284. There's this software from Supermicro called SuperO booster but I cannot find it anywhere & I doubt it will work on my board anyway.

Here's my Cinebench R15 results for the 4180 & 4284. They're extra slow processors. Even my FM1 socket AMD A6-3670K surpasses the 4284 in L1 cache performance.

Thanks. I think if I wanna overclock I need to get a PCIe SATA card like a Marvell HyperDuo controller or some such so I can bypass the onboard SATA which is required when overclocking the FSB on these types of non-unlocked CPUs. Anyway, here's my first video of the AMD Opteron 4284 in action at least until I get these fastest C32 Opteron 8-core 4386 CPU. Too bad its not really any faster in game than my AMD A6-3670K @ 3.4Ghz. Using a Dell OEM Low Profile AMD Radeon RX 550 4GB bios modded & overclocked from 1219mhz to 1375mhz core & from 1500mhz memory to 1750mhz & from 32 watts TDP to 75 watts & lowered the max temp to 84°C so the VRM & Core temp don't get too hot but I left the Hot Spot at 105°C so it can talk a little more on the big end. It's a great video card for $95 shipped, I paid.

Thanks man. So what is the best GPU do you think this board can support? AMD in particular. Also yeah I have pretty well given up on the Matrox. I'm waiting on a GPU in the mail for the system since i had to RMA my RX 6600 XT & I had to put my RX 480 in my Ryzen 3700X system for the time being. I plan on turning this Opteron 4386 system into a gaming system. Right now it has a super-weak 2.6Ghz Opteron 4180 which was surpassed by my other FM1 socket system which has a 3.5Ghz overclocked AMD A6-3670K CPU in it. Would you say the Supermicro board, the H8SCM-F is Legacy non-uefi BIOS? Is that the limitation why it cannot accept for instance a 6600 XT? Thanks

Thanks but according to some people on the FreeBSD (Whatever that means?) forums say it could at least output 1920x1080 16 bit color over VGA. Also according to Supermicro it has 16MB DDR2 dedicated video memory. I think it's my operating system causing the issues possibly. VGA Matrox G200eW 16MB DDR2 Change resolution to 1600x1200 on integrated Matrox MGA G200e in D2939 Fujitsu motherboard | Page 2 | The FreeBSD Forums I think they use this command line like this, it says in the thread. However, I wouldn't even know where to begin... Try these in loader.conf(5): Code: screen.textmode="0" vbe_max_resolution="1920x1080" Code: screen.textmode Value “0” will trigger BIOS loader to switch to use VESA BIOS Extension (VBE) frame buffer mode for console. The same effect can be achieved by setting vbe_max_resolution. Value “1” will force BIOS loader to use VGA text mode. If vbe_max_resolution is not set, the loader will try to set screen resolution based on EDID information. If EDID is not available, the default resolution is 800x600 (if available). Code: vbe_max_resolution Specify the maximum desired resolution for the EFI or VBE framebuffer console. The following values are accepted: Value Resolution 480p 640x480 720p 1280x720 1080p 1920x1080 2160p 3840x2160 4k 3840x2160 5k 5120x2880 WidthxHeight WidthxHeight

So I have a question about the VGA output on the Supermicro H8SCM-F Matrox G200eW (Nuvoton) WDDM 1.2. The only driver I could find that would work on Windows 11 x64 was Windows Server 2012 x64 & it only goes up to 1280x1024 & is very laggy video on the desktop. Is there a better driver available? PCI\VEN_102B&DEV_0532&SUBSYS_BA1115D9&REV_0A Maybe I'll try DevID.info

Cool dude, yeah these days I only buy AMD. Once Intel comes out with 3 threads per core is when I'll switch back to Intel. Until then AMD plans on bringing 3-4 threads per core soon enough.

@pioneerisloudI love that haha me too I love having the experience of every generation, just to feel out the architecture & what not. I've never built an AM3+ FX-8100 or anything with an unlocked multiplier on AM3+ yet & would love to try it out but it's so much more expensive than going the AMD Opteron route. Soon enough I'll have the rig in a case & on my way to building the 16-core AMD Opteron which I believe scores nearly 1,000 points Cinebench R15 multi on a single CPU which is really nice. *PS - I'm stoked to compare the architectural differences between Opteron 4200-series "Valencia" (32 nm) & Opteron 4300-series "Seoul" (32 nm). Were only talking 0.1Ghz difference between the 4284 & the 4386 but they are so f*ing cheap I had to test them all out. I'll end up building a rig for each individual CPU I bought or I may just build 4 systems with 4386s to sell for fun*

@pioneerisloudThanks man. I'm using Non-ECC unbuffered Micron Desktop RAM in the Opteron system now, just 16 gigabytes since it's all I could afford. I'm building like 3-4 systems all at once on a tiny budget. By the way here's a picture of the setup. I need to order more parts like a PSU & other parts are on the way like the case.

Hi. So I got the Supermicro H8SCM-F board in & it came with a Six-Core 4180 Opteron 2.6Ghz & a copper heatsink free. I barely paid anything for the board which came with a cpu & heatsink. Anyway I cannot get the ram to run at 800mhz or DDR3-1600, it's only working at 1333Mhz. Is that a 4180 limitation? The board support DDR3-1866 from within the BIOS Setup page. I'm loving this C32 Opteron though so far but I need to get the 4386 3.8Ghz Eight-Core chip in soon so I can get much better performance in game.

Thanks man. Yeah I'm first gonna start with C32 to see what it's all about then build a G34 system afterward. PS - I added a PCIe USB 3.0 card with USB 3.0 front panel header but the BIOS doesn't detect flash drives plugged into it so I cannot boot from drives plugged in it. Do you have any experience with this? The BIOS is from a FM1 socket Gigabyte GA-A55M-S2V motherboard from which I am testing it on. thanks Description: Specifications: Type: 2 External USB3.0 Port + Internal 19Pin Header Expansion Card Chipset: for VIA-VL805 Q6 Bus Modes: PCI-E x1 Compatible Slot: PCI-E x1/x4/x8/x16 USB Interface: 2 External USB3.0 Port + 19Pin Header(2 Internal USB3.0 Port) Transfer Rate: USB3.0 5Gb/s

@pioneerisloudThat Dual Xeon rig looks so sick bro. What case is that, is it 4U Chassis or something? I'm not terribly familiar with the server chassis but I do know the 1U & 2U are a bit smaller. By the way, I used to run dual xeons x5675s with 48 gigabytes of ram & it scored 1,505 points on Cinebench R15 multi. I'm sure my Opteron 4386 rig won't touch it on Cinebench but I heard something about the Core's being not the best for integer math or something along those lines. I'm all about #AMD these days so I wouldn't go #Intel ever again likely. I'm loving #AMD so much these days. By the way what's the maximum GPU I can run on this H8SCM-F supermicro board? I hear they won't work with Navi architecture, so I'm stuck with Polaris I guess huh?

Thanks everyone for the replies. I'll update this thread when I get my parts in & start building the C32 8-core Opteron system to start. Thanks again, Chris

@Avacado Thanks buddy. Hopefully @pioneerisloud May chime in here if he gets notified about me tagging him. Maybe I should define the PLL chip on the board & use SetFSB?

To start out I bought the Supermicro H8SCM-F which will be paired initially with 16 gigabytes of DDR3-1600 Micron Non-ECC ram but will later upgrade to 64-128 gigabytes of DDR3-1600 Registered ECC ram. Not to mention the CPU(s) I bought are the AMD Opteron 4122 Quad-Core for initial BIOS flashing purposes to get it working with the other CPU I bought, the AMD Opteron 4284 Octa-Core CPU. I think the BIOS needs to be updated on the Supermicro H8SCM-F before it will work with the 4284 CPU. My question is, how would I go about overclocking this CPU the 4284? Later on I'll buy the Supermicro H8SGL-F Socket G34 board to use with the AMD Opteron 6386 SE 16-cores Hexadeca-Core CPU. I want to overclock these CPU's to get more performance out of them. What kinds of CInebench R15 multi scores can we guess the 4284 will get & the 6386 SE Single-Socket Configuration? Thanks
