Can a weak CMOS battery prevent detection of a drive
Norm Why wrote:
I read that weak CMOS battery can prevent detection of a drive. I have two SSD drives. One an old Samsung 500GB boots reliably. Drive D: is a new Seagate Barracuda, 500GB that is not detected reliably. I've done everything conceivable with the cables. I've read bad reviews on the Barracuda. BIOS program says CMOS battery is 3V whereas 3.3V might have been when it was new. Is it worth my time to buy a new CMOS battery? Thanks Glad you got it figured out. To answer your question though, a 3.0 volt CMOS battery is fine. If the battery was too low, you'd simply lose your settings. I did *once* have a battery around 2.6 volts that would not allow the machine to post. Thanks for your reply. Unfortunately, no matter what fiddling I could do, the Seagate Barracuda continued to show unreliable symptoms. Read/write errors and failure to detect at boot up. I ran Seagate tools that said the drive was slow, at one time. I read a bad review of Barracuda. We decided it's a bad drive. I have a one year warranty. I bought a 3 TB WD HDD and installed it. I am now doing a backup. Then I will return the drive for a replacement Barracuda SSD. High SSD drives are very nice for instantaneous response, when they work. I plan to run some large programs for medical imaging. When it comes to medical diagnostic imaging, one needs to do it oneself. And you'll need a totally reliable drive for that. Speaking of medical imaging, when I was at my dentist....when they tried to take an x-ray, their computer crashed. After a few attempts, I told them to try a different USB port. All worked fine. I should have had them deduct my technical services from my bill. More than that Philo, Further back in this thread I thought I said I replaced the Seagate Barracuda with a good one. I also bought a 3TB WD HDD for backup. Prior to swapping out the bad Barracuda, I made a backup to the 3TB WD HDD. When I tried to restore, I ran into CPU overheating problems. Not every thermal grease is OK. Second try was "Kryonaut Ultra High Performance Thermal Grease" from thermal grizzly. Overheating problem was solved and restore is working. The CPU I have may be heat damaged. I checked, the best CPU for this Gigabyte main board is Intel Q9650. I had an Intel Q9650 CPU but it burned out. Temperature reached 126C. then screen went blank. I ordered another Q9650 CPU from a reputable supplier. I'll start again. Heat death of a CPU is slow. During slow death, Win10 is a bugger. If you see RunTimeBroker in Task Manager, you know you're in trouble. While it looks like a software problem it is more likely to be a cooling problem. I have a gaming case. I could install two more fans. I ordered 4 RAM heat spreaders. I'll do a before and after check with my IR Laser temperature gun. The screen went blank ? The CPU has THERMTRIP. If the temperature goes high enough (implying the heatsink fell off the CPU), the CPU sends THERMTRIP to the motherboard and THERMTRIP causes PS_ON# to be deasserted. That shuts off the power and removes +12V running VCore. The fans should go off. The CPU protects itself. I have an E8400, which is 1/2 of a 9650. It draws 11W at idle and 43W flat out. Your processor would be double that amount. Maybe your VCore is a bit too high ? The joint between CPU and heatsink would have to be absolutely dry, for it to get that hot. Even with a tiny heatsink with fan running, it should do better than that on cooling. For one thing, the CPU uses throttling to try to avoid a temperature that high. And that's one reason why it shouldn't be hitting 126C. It has one defense mechanism, that reduces CPU capability as a tradeoff for temp. To hit 126C, you really need an air gap between CPU and heatsink. Like if the push pins aren't fastened or something. Paul |

Currently a Quad Q8400 is plugged into Gigabyte MOBO. For convenience I connect using RDP. CPU use is 3%. Temperatures are 40C., 36C., 32C. and 36C. I think core#1 shows heat damage. Electromigration occurs when things get too hot. |

Let's compare specs: Halnziye: HY710 10g Silver Thermal Paste. Halnziye HY710 10g Silver Thermal Paste has decent level of thermal conductivity at 3.17W/mk.

Now I will have a Q9650 in a GIGABYTE main board, 6 SSD ports, 2x 500GB SSD drives and one 3TB WD HDD. Also a bunch of other stuff that is not part of this discussion. Why such a proliferation of inadequate thermal grease products? Gresham's law is a monetary principle stating that "bad money drives out good". Likewise, so many people settle for bad grease.

I've spent a lot of money on bad grease. The good grease worked for me. On the new Q9650 all the cores are below 40C. It can take two weeks for grease to 'set'. That means the idle state gets cooler and cooler. Typical low CPU load core temperatures of the Q9650 a 31C., 31C., 28C. and 32C. Thermal Grizzly Kryonaut thermal grease works great! However, the MOBO manual suggests that optional fans be installed to avoid overheating. The manual can be found by Google'n 'Gigabyte GA-EP45-DS3L .PDF' I have a Cougar MX330-X gaming case whose manual can be found he https://cougargaming.com/fileadmin/d...usermanual.pdf Note that 5 optional fans can be installed. CPU and Fan N are installed and their 4-pin fan headers are occupied. According to the MOBO manual there are 2 3-pin fan headers up for grabs. I am confused. How do I get support for maximum number of fans. Where to buy? Thanks According to the BIOS, installed fans can be set to sound an alarm if fans fail or CPU exceeds 80C. However, the beep speaker has been silent for a long time. There is an little known beep code. The absence of a beep confirmation at boot time indicates something is wrong. Maybe what is wrong is the beep speaker? |

Switched fan power would not so report. The question is which fans should be connected to the 2 3-pin fan headers and which should be power switched? And where to get the power? Thanks. A motherboard can have fan headers that only provide power (+12V and GND). Check your manual for details like that. A motherboard will have at least three channels with RPM counters. (+12V, GND, RPM). The RPM signal is 2ppr, two pulses per revolution. THe most exotic headers, are ones with speed control. In the old days, the three pin connector could have voltage control of the +12V pin. There would be a 100uF cap next to the fan header plus a transistor. On modern motherboards, the header is a four pin, and has +12V GND RPM PWM. The PWM is a pulse width modulation control that sets the fan speed. The RPM has the 2ppr thing. The +12V in this case stays at +12V. You save the fan headers with working RPM pin, for the fans that have an RPM signal :-) The cheapest case cooling fans, have no RPM signal. They just have +12V and GND. You connect them to unmonitored headers, or get a Molex to fan adapter and power the fan that way, The next level of fan has an RPM signal. You can plug those to a three or four pin header equipped with RPM. The CPU fan header pretty well always has RPM. The CPU cooler has the third wire with the RPM signal on it. The more modern CPU fans have all four wires +12V GND RPM PWM, even if you're not using the PWM and have decided to run the fan at full speed. Based on the above, you have a pool of electromechanical devices, you have your various fan headers, you have molex connectors, now you head off and do your planning. Nothing says you need seven fans, to have a "lucky" computer. My newest machine, has one fan on the back (to establish a low delta_T between inside case air temp and external ambient). It has a second fan positioned as a blower over VCore, as VCore doesn't have proper cooling and runs at 65C surface temp. The CPU cooler is huge, and it has a fan with both RPM and PWM. And that's it. If the case air is getting too hot (warm cloud around CPU cooler), then I use the 37.5mm thick fan and put it in the back of the computer for exhaust. Generally you aim for a "direction" of airflow. Like input on the front, exhaust on the back. And arrange the fans so they're not working against one another. For example, it's pretty hard to install a "side" fan in the door, and arrange it so it has a deterministic airflow. I did do a seven fan setup once, and one of the fans, if you held a tissue next to the fan, there was zero airflow, which tells you the fans were working against one another. Paul |
