No problem. i wish you the best in your search.

i have 4 of the 61xx ES chips.

i'm talking about Piledriver "ES" chips. Not standard Piledriver Opterons.

i've seen some overclockers using SuperMicro boards overclock via an additional board which taps into the bus that controls the voltage controllers. Specifically it was an Elmor Labs I2C board. Unfortunately i don't have time to look into it now. i think i saw it on Der8auer's videos...

They aren't easy to find. Rare as hens teeth.

i still run two of the Piledriver Opteron ES chips in my SuperMicro H8QGi-F. i also have 4 of the Opteron 61XX ES chips which i am not currently using.

here is the OCNG utils. hope it helps

Have you run memtest86 or memtest86+ on the ram? i would do this first to determine if you happen to have a bad stick(s). Is all the ram the same brand and type? If you find that you have a bad stick then its going to be trial error to find which one. Not a fun experience, after i flashed...

i am not sure that voltage is limiting you too much. i found that the voltage requirements to increase the GHz really starts climbing after about 3.8 GHz. i run with this TPC script: cd C:\tpc TurionPowerControl -fo 2 TurionPowerControl -set node all core all pstate 0 freq 4400 vcore 1.3250...

How is the optimization going? i haven't been able to run the NB at more than about 205 with stability. i still have the issue where under stress testing the machine will just shut down, but at this point i am thinking that it is a matter of the motherboard simply not being able to supply...

It is not so bad with only 16 cores going full chat. About 480 watts for the entire system using the Kill-A-Watt. Idle is around 260 watts. This is with all pb1 (all core turbo) set to 3.9 GHz, and pb2 (single core turbo) set to 4.4 GHz (which is 4.0 GHz and 4.5 GHz after multiplying by the...

hi Folks, i've been running a quad socket SuperMicro H8QGi-F motherboard with Opteron 61xx ES chips since 2015 as my home PC. 48 K10 cores overclocked to 3.0 GHz. The thing has been a tank, and solid as a rock (and it should be since the internals plus the SC748 case weigh about 80 lbs). The...

[EDIT] i found out after a bunch of further stability testing, that the lowered speed HT setting just kept the stability from manifesting itself (ie it hid the instability for longer during my Prime95 runs). The problem actually was the Node Interleaving setting in the BIOS. For some reason...

Update: With the processors still set at "Compute Unit" downcore mode i spent some time focusing on the voltage curve and pstate 1 (pb1) since that is where the CPUs spend most of their time. 3.9 GHz required 1.2125 volts 4.01 GHz required 1.2375 volts i stopped at 4.0 GHz since i don't want to...

i thought i would post some preliminary results. Using OCNG the processors seem to have hit a limit at current settings at ref clock 213. Beyond that is not stable at current settings (and i don't want to up voltage to CPU-NB due to increasing heat). RMMT really stresses out the CPUs more in...

Perhaps i should not be amazed by this, but to properly overclock this, i am having to *reduce* voltages. refclock of 210 would not work when running rightmark multi thread benchmark saturating all memory cores. The memory was not the problem, but i noticed when i reduced the CPU-NB voltage...

i thought i would add some initial impressions. Initial attempts at overclocking with all 16 cores were not so promising. But that was compounded by the fact that i was switching to the wrong pstate prior to setting the processor voltages. This screwed up the windows timer causing all manner...

Just installed the 6380ES chips in my H8QGi-F tonight. Haven't really played with them much. Just set OCNG to the same settings for memory that i had with the 6328s. Temps stabilize at around 43C with psmax -1 set, with Cinebench R20. The 6328s would top out at around 27C. Ram bandwidth...

i just recieved my 63xx Extra Spicy chips today. Will be putting them in over this coming weekend. In the meantime my 6328s have been running just fine (ie completely stable at 211 ref clock) - 3.7 GHz all core turbo, and 4.0 GHz turbo. Will report back later.

For me the Noctuas worked much better than expected. Back when i was running confirming stability by running IntelBurnTest for hours and hours on end, with all 48 cores of the 61xx ES at 3.0 GHz, IIRC power draw at the wall was around just under 1000 watts. Temps stabilized at around 55-56...

i have some 63xx ES chips coming to me in a few days. i will report the differences in temps between these and the 6328s that i'm currently running. When i was running 61xx ES at full bore, temps stabilized at around 55C.

Thanks so much for running that. Perhaps one of the thermal measurement devices on one/both of my chips is bad. Tear had mentioned that they had run across this before. i will be replacing these 6328s with others in about two weeks. i am running NH-U9DO A3 coolers. Heat was indeed a problem...

Ah, thanks for the memory explanation. i was previously running Opteron 61xx ES (unlocked) chips. The 61xx ES chips were actually more stable that the current stock 6328s. With the stock 6328s, there are programs that will reboot the machine every time. The first one that comes to mind is the...

i'm curious why you are running the ram at ddr3-1333 when OCNG gives you the ability to run at ddr3-1600 with fast timings? PS: as far as being able to run higher frequencies - i'm running Opteron 6328s (these have an all core turbo of 3.5 GHz and single core turbo of 3.8 GHz). If i just run...

hi folks, i've been playing around with some Opteron 6328s as these have the highest frequency for the G34 6300 series. The -psmax 1 trick does help. i've not been able to get it into pstate 0 however to hit 3.8 GHz. When the OS is handling this it occasionally does hit 3.8 however. Any...

i fixed the link to the one on the web archive since that one still works. PS: My Quad Opteron (SuperMicro H8QGi-F running OCNG, and Extra Spicy cpus) is still running strong every day.

hope that helps.

The bios is still downloadable here: https://web.archive.org/web/20191104122812/http://darkswarm.org/sm-bios/ocng5-5.3-20151222.7z i verified that the zip is the same as the one i downloaded in 2018 the ocng utils link is not on the web archive though.

i think i have it on a folder somewhere. i still run it on my Quad Opty. i just took a look over at: http://area51dev.blogspot.com/p/ocng5-step-by-step-usb-drive-setup.html and it doesn't seem the download link works any longer :(

Just thought i'd let you know that they are still running strong and just fine 4 years later :) currently running OCNG, which let me run DDR3-1600 ram. Unfortunately DDR3-1866 did not run at that speed (ran fine at DDR3-1600 at slightly lower latency).

i'm running two SuperMicro PWS-1K41F-1R 1400w power supplies (these come with the SC748 case). Board is H8QGi-F. CPU wise i cannot go any further than around 3.2/3.3 GHz on all cores. Cinebench 11.5 maxed out at 39.82. As you mentioned... over 1000w at the wall socket as well. Temps are a...

VRMs are not heat sinked now. However, i'm running this in a modded SC748 case (drive cage removed replaced with extra 120mm fan, added an extra GPU fan in the back, fan controller controlling all the fans, higher flow fans on the Noctuas)... so plenty of airflow below and above the motherboard...

hi Patriot, i've been attempting to overclock the CPU/NB on my rig to almost no avail. Currently running 4 61xx (2.1 GHz "stock" speed) Extra Spicys at 3.0 GHz and running OCNG 5.3. default MHz on the CPU/NB is 1800 MHz with a voltage of 1.08x volts and i'd like to raise that as much as i...

hi Folks, I'm running OCNG 5.3 on my H8QGi-F running 4 Magny-Cours 61xx Extra Spicys at 3.0 GHz. OCNG allowed my existing G.Skill memory to run at its rated XMP profile at DDR3-1600 (CL9 at 1T) - its set to manual in the bios at 800 MHz. i was wondering if anyone has had success running the...

i was experimenting with upping my ref clock... in order to overclock the northbridge and gain a bit of additional performance on the L3. i was going in small increments. 205 was fine. 210 booted but i was experiencing random shutdowns. i set things back to 209... and Windows would boot but...

yes.

i think for the folks running stock (ie cpu multiplier locked) chips this is not a bad option. On my rig i still use TPC since i clock some of my cores up to their maximum... 3.8 GHz. i wish there was a way to set the CPU-NB multiplier separately... without affecting ram and cpu timings, since...

nvm, turned out to be a single bad stick that would run DDR3-1333 CL8 just fine but not at DDR3-1600 CL9 and 1T... after replacing the bad module the system now runs at DDR3-1600 at the XMP profile timings but at 1T instead of 2T.

hi Folks, i recently flashed OCNG 5.3. After the flashing procedure (after flash and running holes)... all the CPUs came up running at DDR3 1600 just fine. i then booted into windows just fine. Ran OCNG utilities and set XMP etc. Ran fine for a bit... had a shut down. Rebooted (2 beeps...

how's the Win 7 compatible version coming along?
