Great! Post how you did it (include things like did you remove the old compound from the chips, what you put on, screw torque amounts, etc) so other people can do this as well.
The Ebay coolers are a bargain....

I have two Monarchs that seem to have faulty temperature sensors and they stop hashing very quickly after bootup. Any way to fix the problem?
I have another with 15% HW error rate, any ideas on this?
15% error rate is not a big deal, a few engines are screaming but they don't really pull power. As long as it hashes well let it be.I have another with 15% HW error rate, any ideas on this?
As for the faulty temp sensors, are you sure the water blocks are running? Listen for the water at the radiator top, then check around to see if there are any signs of leaks around the water blocks/pumps.

I believe you are correct, sir.
I can hear fluid when I shake it, but I can't hear any fluid moving when I turn it on. I can tell at least one of the pumps initiates, but the copper blocks heat up immediately, some shares are accepted and then when the temp reaches 85 they shut down. Too little fluid perhaps. I have ordered new cooling units, I'll see if that fixes the issue.
Another issue, I have a 700gh unit that only hashes at 320gh with bfg 4.10 and 400 with BFL custom bfg 4.2. Could this be another cooling issue with one of the units shutting down?
I am having the exact same issue with my 700gh unit. What time s the other cooling unit u are ordering? Do you have a killawatt attached to see wattage draw? Mine seems to spike over 750 watt usage when I turn it on
Good news. Lightfoot was correct, the issue was the coolers. I replaced the two non-functioning units and the monarchs are now hashing along nicely. I am going to try replacing the cooler on the 700GH unit tomorrow.

that is what i am getting. Just looks like it overheats. Fans are working and feels like the water is pumping around.
Stupid question, do you have a separate fan blowing on them? I used a floor fan and it made a big difference. Test the direction to be sure you're not blowing the hot air back into them. If you find another solution please post it.

Does the code for the cfminer coding transfer 100% to bfgminer?
Does awesome miner work with monarch BFl 700? In order To do cryptomining auto switching

I got my two 500ghs monarchs running off the BFG 4.2 provided in this thread but only pulling 280 watts at 350 ghs. My 700 ghs keeps erroring out with the 4.2 bfgminer
When you say erroring out do you mean the "sanity check" or it stops?
Mine did a lot of sanity checks then it would warm up and run ok. Kept a fan on it so it wouldn't overheat but made some coin on it...

I'm having major issues with my 750GH/s Monarch. When i plug my 500GH/s versions into my PSU, they work fine. But when i plug my 750GH/s model in, nothing happens. I have to turn the PSUoff and on again to get it working with my 500GH/s model. Please help!
Can you check the resistance across the pcie pins to see if it's shorting out? One failure mode on the Monarchs is the high side FETs short due to overheating which crowbars the power supply.C
I don't have a multi-meter to check for resistance, however i have discovered that its plugged in and i attempt to powered it up, it smells of burnt plastic and i even thought that i saw a little smoke from one of the pumps or something.

I have a couple that are doing weird things as well, I will try underclocking based on Kuschelweich's post and report back.

Error rate is only this high with the custom BFL bgfminer 4.2. On 4.10 it seems better and hashrates are higher. However, I'm getting a "failed to find work for queue results" on one Monarch and the two with temp monitor issues do not show up at all.

Don't open the loop unless you have a spare heat sink set (some guy is selling them on Ebay for $20 each, if your Monarch had a leak in the cooling system that's a nice fix). Those things run the chips quite warm (60c) and any disruption in cooling will blow the chips since it is *very* thin (which really helps with heat dissipation).
Use the V3X and FBX values to slow it down, remember the second digit is hexidecimal but voltages above 4 are locked out) and have fun with it.

do we put the V3X and FBX in the .conf file? Trying to find the syntax, but struggling to find the answer.
BFL had a underclocking manual for these, it's somewhat brief but does explain this a bit. I'll see if I can post the manual here, but here's some excerpts from it:
Passing commands:
Code:
bfgminer--set bfl:_cmd1=F0D --set bfl:_cmd1=V5X
Setting Frequency:
To set the regular frequency, command: ‘F’,’
For example, to set the frequency to index 3 in regular mode, ‘F3X’ must be submitted. To set the frequency index to 1 at 2x mode, ‘F1D’ should be used. Once either command is issued, the on-board controller recalibrates all the engines on the board to decommission the ones that can’t operate with the new frequency setting. It is HIGHLY recommended to set the core-voltage to proper value before changing the frequency.
Since the on-board ASICs use Ring-Oscillators, frequency index cannot be accurately mapped to any number (variance could be as high as 40%). Temperature and core voltage will affect the frequency as well.

Has anyone tried using the BFL Monarch in the PCIE slots in their PC?
I've ordered 3 BFL Monarchs that are arriving on Thursday to try out for fun and was wondering if anyone had actually tried putting them into their motherboard. I'm getting the 500Gh/s versions so just one will be pulling about 290w from my computer's PSU (I've plugged an Antminer S1 (350w) into it in the past with no issues but it was sketchy af
). I couldn't find anything online about someone trying it out so i thought that i would ask, if not ill be sure to try it out
It should work: Use the BFGMiner 4.20 code on them and it will pick up the PCIe slot. There is no performance difference and you still need to mount the radiator but it will work.I've ordered 3 BFL Monarchs that are arriving on Thursday to try out for fun and was wondering if anyone had actually tried putting them into their motherboard.
