    Exclamation GA-EP35-DS3L Processor Voltage Problem

    First off i couldn't get this board to raise the voltage on the processor unless i reset the cmos, you could set whatever voltage you wanted but the bios wouldn't raise it, to make sure i just wasn't seeing vdroop i upped it a pretty good amount and checked it with cpu-z to confirm not changing, resetting the cmos fixed it.

    BUT now whenever my system is shutdown for an extended period of time (like overnight) the bios sets the voltage back to default for the processor installed, which in my case means the system will reboot and lower my overclock. If i reset the cmos again i can then set the bios back up and reboot to my hearts content and even shut the system off for like 2 hours and it remembers, but if it's a long period of time then it gets set back to default.

    Current BIOS F4
    C1E and EIST are disabled.
    I didn't install the DES software.
    Processor is E2200
    Super Talent 2x1gig 800mhz
    FSP Group 450w Dual Rail PSU

    PS: Newegg reviews on this mobo show the same problem, so maybe there's a bug in the bios...

    Check In Integrated Peripherals And see if you have Legacy USB Storage Detect Disabled, if not disable it. This may help you there

    You Should also Disable TM2 and C.I.A.2 to do any overclocking.

    Also, whenever you update or clear CMOS and reflash the bios you HAVE TO choose load optimized defaults, then save and apply and reboot. Then go in bios and make your changes. If you do not do this then that could leave parts of the older BIOS code in the eprom, so if you did not do this please reflash to F4 in Qflash NOT @BIOS and do it that way it is a MUST

    If no luck let me know and I will post a template to get you to post back all you MIT settings for me

    Already had it disabled.

    Over the past week i've reflashed all the way back to F1 (using Qflash) and then forward hoping to find one that didn't have this problem, unfortunately they all do; and yes i always load optimized after clearing an saving an exiting then going back in and setting up my config.

    Like i said it does retain the change until system is off for an extended period of time, CPU multi x9, 333 buss, PCIE 100, CIA2 Disabled, Perf. Enhancer Standard, memory x2.4, mem timings 4-4-4-12, mem advanced on auto, system voltage on manual, DDR2 v +0.3v, cpu voltage 1.45 with vdroop to 1.42.

    I'm not gonna mess with it anymore, this is clearly a bios issue, many others are having the exact same problem getting it to retain this one setting on a cold boot.

    I've been building systems since they started letting you purchase your own mobo's off of egghead, this is nothing new to me, only reason i posted here was because someone from Giga reads the posts here and that it might speed up a fixed bios. Didn't mean to imply that i needed help - sorry.

    Ahh I got ya! Just trying to offer some suggestions. Yes there is some BIOS issues for sure

    Good luck

    Exclamation Re: GA-EP35-DS3L Processor Voltage Problem

    Am I frying my core duo with a GA-EP35-DS3L? Bought this new board 5-14-08 & manually set the CPU voltage to 1.3 volts @ 400Mhz x 9.5 = 3.8Ghz on an e7200. Wow!

    Next, I installed SpeedFan (system utility software - google it) and freaked out to see the core voltage on the other 2nd CPU core was elevated to 1.9 volts vs 1.28v on the 1st core!!!! The temp was up 5-7 C on this 2nd cpu core too!!!
    Isn't this 1.9 volts frying my second core and damaging the CPU???
    Overclocking with Auto settings is even worse, because it uses 1.4 to 1.5 volts on the 1st core!!! It had the voltage up to 2 volts on the second core.

    Help!!! Is this BIOS voltage problem destroying my CPU?

    Also, I bought three of these Mboards, so should I try another one? Is this first system build possibly a defective MB or is this an BIOS issue with this MB or is this something else???

    Thanks for your help.

    The system is Vista 64bit with 8gigs of G.Skill 1000Mhz and this PS Rosewill - Price, Quality, Services

    Air cooling with giant CPU heat sink and plenty of fan cooling support.

    Edit: See post 7 just below. I was misinformed about what VCore2 was reading.

    Use RealTemp to see your 45nm cpu temps, everything else just ahs not caught up yet, And I would assume you can disregard that voltage as well. I doubt it is correct. What does CPU-z Show for voltage (I know you say one core, but just asking)

    If it was 1.9 your CPU would shut down instantly so that is just a misreading of a sensor

    You could try another board, but likely will see similar readings, most apps are rarely spot on, and again most of the reporting apps have just not caught up with 45nm processes yet to get them any closer to being correct

    ATTN: SpeedFan Info about VCore2...

    I found out that VCore2 in SpeedFan, which is an excellent freeware/donate program btw, is reading the MEMORY VOLTAGE. So everything was/is fine.

    The FAQ and info at the SpeedFan website was not informative enough about VCore2... and I'm not knowledgeable about the ins-n-outs with overclocking... my mistake.

    Ahh, glad you figured it out, RealTemp is also free. Did you need a link to it? Just ask because the way you worded that sounded like maybe you thought you had to pay for it.

    Here is link and info/calibration page
    Real Temp - CPU temperature monitoring

    Here is the calibration info and calibration page as well
    Real Temp - Documentation

    I had not used speedfan in so long sorry about not knowing that vcore2 was your ram. I do know you usually have to configure them all though, I thought you had and was seeing that issue.

    Either way, good to see you got it squared away

    Hi I have am also experiencing the same problem with the GA-EP35-DS3L - you can set the CPU voltage and it will stick for a while, and then after a few days it will revert back to the default voltge, even though the bios settings show that it should be at a higher voltage.

    It's very annoying, I hope GIGABYTE are working on a solution!!???

    Go to gigabytes website http://www.gigabyte.us/ and at the very bottom click contact, then scroll down again and click technical (it's in blue) and send them a notice about it.

    I contacted them but it fell on deaf ears, they refuse to admit anything is wrong with the bios, they gave me every excuse they could think of then they ended it by stating overclocking results are not guarenteed, but the more people that let them know about it maybe they will atleaste investigate it, it's very easy to reproduce this issue.
