Thread: EX58-UD5 Diagnostic LEDs gone out!!




  1. #1

    Unhappy EX58-UD5 Diagnostic LEDs gone out!!

    Hi,

    I put together my new PC about a week ago just with my stock CPU cooler (i7 920) and booted up and everything ran fine. The voltage/temp LEDs all lit up when I powered on.

    I changed the CPU Heat sink yesterday to the Swiftek GTZ with i7 adapter and since I've used this the LEDs on my UD5 for North Bridge and CPU voltage/temp ceased to light up!

    So my question is to anyone reading this, what could caused this and is it likely to be permanent? Also if it's probably permanent how useful are they anyway, and is it really worth going to the trouble of stripping my system down so I can have some nice LEDs lighting up?!

    Ive been using RealTemp for CPU temps CPU-Z for Voltages but I wasn't sure what to use to monitor North Bridge Voltage/temp. How accurate are these programs anyway, or the MB's LEDs ( as when I put the RAM onto its correct speed I used to get Red for CPU Voltages but I'd actually get 1.18v in CUP-Z!)

    Any help with any of those questions would be appreciated!

    Hmm I don't know, did you ground your self properly? remove power from the board? HWMonitor or everest in the tools thread will accurately show temps for cpu-tcase, system/motherboard and northbridge. try unplugging the power, maybe clear the cmos and see if anything like that could resolve it.

    Thanks for the response DankBuddha, but I feel like a bit of an idiot now! My CPU LEDs do light up, just moving from stock cooling to water cooling meant that the idle temps never got near the threshold! (They did last night when I OC's my CPU though!) But thanks for the info on those programs I haven't tried HWMonitor yet.

    Also when it comes to OC'ing an i7 920 what's the best way to test stability? I can boot to windows with vcore of 1.2 @ 4GHz but I know that this isn't stable, after 15minutes Prime95 and then a bit of Crysis. I found the "official" Gigabyte guide and followed that to start with but vcore 1.4v was giving me 74 degrees at full load after 15minutes! Where the Vcore 1.2 was low 60's - So obviously I want it to be stable but as cool as possible, so any tips would be welcome.

    Thanks

    if the system can do 20 passes of linx, a couple of hours of prime95 and memtest+ then it's rock solid. Again these can be found in the thread "latest overclocking programs..." For better temps just start with some voltages and raise or lower till you find the lowest settings that are stable. Take time but worth it in the end to find the lowest stable for better temps and the hardware to last longer.

    Thanks again DankBuddha I'll spend some time doing that tonight hopefully I can get it stable around 1.25-1.3 so the temps don't get too high. Plus I think I went over the top with the thermal paste so I might reseat and clean my CPU/Waterblock and try and knock a few degrees off once I've got it stable.

    Thanks Again!
