Are older motherboards fine for mining?

Hi there guys, I was wondering if there is anything against building a rig with older hardware, I mean Core2Duo 2,3GHz on a P35 chipset motherboard.
What should I worry about? Have you ever had any problems with dated mobos?

Thanks :smile:

    I got couple rigs on very old mb. They mining just the same like H81 pro btc.

    Should work fine, I use an ancient Dell Dimension w core2duo (from 2006 I believe) as a test rig but are limited by it's 3 pci-e slots.

    I would actually say some of the older boards and chipsets are more stable then a lot of the modern mainstream stuff.

    My test MBs Asus P5B Deluxe wifi (P965) and Asus P5K (P35) :) with Xeons 5420L work slightly faster, then H97,H81 with G1840 :)

    @HelloWorld Hi, i know this was last year but I'm struggling with my p5k deluxe: i cant get it to recognise the third GPU in pcie x 16 slot 2, code 12 not enough resources. Did you have this trouble and is there a way round by disabling things that share the same IRQ? Thanks for any hints!

    They work but can be awful at electricity usage. That core2duo probably uses 50+watts at idle. A more modern board and low end cpu use 20-25w at idle.

    AFAIK the second PCIe slot shares line with all the x1's, the manual says you can either use the second x16 or all of the x1's. I do not know of any workaround to make it work.

    Thanks Bro, I used both PCIE x1 and the first PCIE x16 slot in the end, apparently no conflicts as the manual states the first two slots don't share lanes. Appreciate the reply :)

    Hello everyone, I tried making a new thread but it isn't getting approved\spamfiltered

    Hopefully someone will be able to help me:

    I'm a relatively new miner to ethereum

    I dabbled in mining back when bitcoin wasn't profitable, but alas these many years later i now see i could have been rich hadn't i formatted that hard disk a million times since then. But I digress

    Today I'm here asking desperately for help. I've tried every online resource available to no avail

    My miner crashes after OpenCL - this leads me to believe it's a driver issue

    However, when I first hooked up the rig and got all the startup problems resolved, the Win7 that was on the hard drive did a test run and even mined a lucky share, without any crash.

    After hooking up the other cards, I flashed the bios on one of the XFXs (I already have a rig running so I'm pretty sure i did it correctly) and it crashed but i tried again on the default bios, too - crashed again. I tried Win10 then since people online reported less issues with it, same thing.
    Disabled any overclocking in Afterburner - same crash, I tried Win7 again, same crash.



    SPECS:

    Gigabyte EP45-DS4 with latest bios
    E5400 Dual Core 2.7
    2x 1GB DDR2 Kingston (667) RAM
    RealPower 650W > mobo + 1 card + SSD
    Corsair TX750 > 4 cards
    -hooked in series? with a psu connector from ebay, i power them both on at the same time
    5x XFX RX480 8GB
    -three on 1x risers 1 directly on second PCIE 16x on the motherboard and one on 16x risers from the last 16x PCIE slot
    SSD Samsung 60GB
    Win10 Pro Pre-activated [gen2]






    MSI RX470 (inactive)

    So. Why does my miner crash after OpenCL, and what can I do about it?

    I have 16GB Virtual memory set. I tried a wide range of drivers, each one safely removed and reinstalled with DDU in safe mode.
    Before I go into any purchases, I'd like to get some more experienced advice
    Additionally, Win10 also reads only 2 cards, while on Win7 I had all 5 cards detected, but couldn't manage the 5th (options were greyed out)
    I found online that this motherboard's 16x slot shares the lane with 1x (post above) so this might be part of the problem, but then again some russian forum that I translated mentioned a guy plugging in 1 card, having everything work, and then plugging the remaining 5 at once after that and everything worked for him right then and there

    I tried to give as much information as possible. I know my way around computers more than the average Joe, but I'm by no means expert! I don't know much about the inner workings of the motherboards, and I have to admit the electricity part of it i don't perfectly understand so I might have done something wrong (I'm a civil engineer :p )
    Please offer any sage advice or roasts, as preferred.

    I have a pic of the build if it helps
