    Default 8g memory stability issues with EP45-UD3P

    I have built a new system to just mess around with and have no intention of overclocking. This system ran flawless for about 3 weeks and out of no where I get BSOD with memory dumps.

    It sarted as just one BSOD one week and then by the next week I was having one daily for about 3 or 4 days. The first error was a driver error, second was a bios clock error and the third was something else (sorry for not having these exact but the screen was quick).

    So first thing is I test the memory and its fine. So I boot up some more only to see that i have a black screen that blinks where I should see a splash screen or POST. After a couple reboots, sometimes it doesnt show my PCI list. I called Gigabyte and they said just RMA and newegg return was out so I bought another one. I get it all put together and same exact thing only now it BSOD right as I get into windows instead of letting me use it for a little while. I tested my PSU and all is good. I swap the graphics card just for the hell of it and still BSOD at startup.

    I now leave this with a memory issue so I take 2 sticks out of board and everything seems fine. I take those two out and put the other two in, it works fine and passes Intelburntest(Dual channel). The timings and voltage are what GSkill calls for so its not that I dont think???? I have also loaded Optimized each time.

    EP45-UD3P rev 1.1 on both boards, tried with two diffeent bios but currently with F7 on the new board, old board had up to F8 on it.

    I grabbed this template out of another thread so hope it helps. If it is blank then it isnt on the screen i was on or have no clue where or what it is. I just find this weird that it seems fine unless I put all 4 sticks in and it worked fine for several weeks with no problems. Btw, motherboard says 34 degrees for CPU and 38 degrees in case (that is all 4 sticks when it ran)

    Well I see some issues, especially for 8GB

    Please post your Full specs and a link to your ram or the model # so I can best advise. For now I advise you to change these things >>>
    Performance Enhance ...................... [Turbo] <<< Set to standard

    MCH Core ............................. 1.100v [Auto] << More is often needed with 4+ GB, so try 1.2-1.34 and if you have no luck with that also try 1.05.

    The performance enhance setting on turbo may be your main issue. But I would advise you set a few other things at least when using 8GB, or all of them if you would like. But I cannot advise until I have your specs and the settings you are using now

    Those settings in the template you grabbed are for a X58 board, that is why you could not find things right. Here is a template for your board, if you give me your full exact settings I can better advise. Please also post me a screenshot of this program running so I can see what you are getting for some values if you are using Auto >>

    Sorry about the memory part number, I am using a temp computer and didnt have language pack installed and then their site is down otherwise I would have linked it.

    F2-8500CL6D-4GBNQ is the memory i am using. Which I swear was on the list of memory for that board, something I always do before I buy it and I know I looked it up (maybe clicked the wrong board). Also noticed that the GSkill site said 2.0v but the tag i got on the memory says 2.0-2.1v.

    Please note that I still have only 4g in that computer and is running stable so I have posted all my settings as they are without changing any of them like you bolded below. Figured you might want to see all them first plus do I need to put in the 8g before changing these settings, becuase half of the time when the 8g is in, i do not get a post screen to hit del to get into BIOS which I thought was weird. I also bolded some stuff that was different than what you posted.

    I know this is a lot on Auto and you asked me to change some stuff but I want to be sure you know what my settings are. I can always refer back to your original post for changes. I thought about the turbo being turned on but it says put on standard if OCing which I am not (although it is 1066). Sorry my attachment is so big =(

    Somewhere here I guess I screwed up, to me it looks like I should have just gone with 4g of memory or not get 1066. I dont mind changing all this stuff to get it to work but I still feel this is me doing something I shouldnt.

    What caused it to "break" tho and get gradually worse .Since you replaced everything except memory and cpu.
    Did you reinstall vista 64sp1 on the pc with just 4 G running,and then go for 8.
    Do you still have the 4 sticks in their matched pairs or are they all jumbled up now?
    The 38* sys,34* cpu sounds a bit high for stock.
    Were those the temps shown using "pchealth" in bios?
    What sort of temps do you get while running under load with the 4 G?
    Did you boot up at all into windows with the new mbrd and 8G?
    Possibles:
    Mount a 120mm fan over/angled on to the memory slots and northbridge chip.Connect it up to the sys2 header?.
    they dont cost much and even if you stick with 4G it wont do any harm.

    Underclock the cpu/memory a little and see if the 8G will run again?

    Default Re: 8g memory stability issues with EP45-UD3P

    I will answer the questions below then give a little background about the issues.

    What caused it to "break" tho and get gradually worse .Since you replaced everything except memory and cpu. I don't know. Doesnt make sense to me.

    Did you reinstall vista 64sp1 on the pc with just 4 G running,and then go for 8. No it has always had 8g in it until I got to testing the memory sticks by removing them (more on that later).

    Do you still have the 4 sticks in their matched pairs or are they all jumbled up now? All brand new and all the same ones.

    The 38* sys,34* cpu sounds a bit high for stock.
    Were those the temps shown using "pchealth" in bios? Yes

    What sort of temps do you get while running under load with the 4 G? All the temps I have seen have been in the bios, not in the windows enviroment and to tell you the truth, i didnt look when I did the Intelburntest. I do know that anytime it has crashed or even after gaming, the temps have always been pretty close to that number but its in the bois after I restart.

    Did you boot up at all into windows with the new mbrd and 8G? Yes, it worked great for a little while. More below.

    Possibles:
    Mount a 120mm fan over/angled on to the memory slots and northbridge chip.Connect it up to the sys2 header?. My CM case has two fans on the side, one kinda over my CPU fan and one between the memory slots and video card.
    they dont cost much and even if you stick with 4G it wont do any harm.

    Underclock the cpu/memory a little and see if the 8G will run again? This is my next dilemma. I wasnt trying to be all cool with 8g so much with hopes of OCing. I just had to wait for my 64bit disc to come in so I said what the hell and bought 4g more memory cause its not that expensive.


    The system was bought and put together with everything new including HD, OS and 8g memory. Everything installed great and worked without any problems for 3+ weeks with all 8g in the computer. Both windows and the BIOS have always seen all 8g of it. About 4 weeks into using the system I got my first BSOD and it said it was a driver conflict. I checked all my drivers and they were good. It worked fine for about another week then I recieved about 3 BSOD over a coarse of 4 days. All different errors and I was doing something different all 4 times. From playing a game, streaming video, opening IE and a couple other things. I used memtest and everything came bacck fine. About 2 days later the BIOS splash screen/POST did not show at all (black screen that blinked) and the PCI list showed up about half the time but I could boot to windows and use it as normal except the obvious issues above. I flashed the BIOS to F8 and still the same. The computer just turned it self off the next day but would come back up. So I called Gigabyte and they told me to RMA it and since the newegg RMA was up by now I just ordered a new one.

    I installed the new MB again and all 8g. Loaded optimized settings and set the DRAM voltage to 2v. Did the same exact thing except worse now. Now out of about 10 reboots I got into the windows enviroment about once. The rest of the time was about a 1 sec flash of a BSOD as windows was loading. I then tested the PSU (Corsair TX 750) and the voltages are fine. Swapped the video card out (EVGA 280) and still messing up. So now that I am at the point to believe I have a bad memory stick or something, I remove 2 sticks of memory and boot it up. Everything works fine, open a lot of programs, close them, run the windows experience thing then Intelburntest. Everything is fine including the BIOS screens. So now I think I know its got to be one of the other two sticks, well I take the 4g out and put the other 4g in. Guess what, everything is fine on those two sticks. I do a search about 8g memory/4 sticks memory on gigabyte boards and I end up here with what seems to have all kinds of issues but maybe with just OCing because settings and such.

    To come back to the last question you asked about me underclocking the CPU/memory and just in general. It seems to work fine with 4g, is it really worth the 8g especially if I have to underclock stuff to get it to work. I mean it sucks how much time and now some money I have spent. I would hate to see 4g just sit on my shelf especially if I can get it to work. But to have stability issues will just suck, hence why I didnt want to OC in the first place, didnt want to have to mess with all this. But now that I am in it, guess it doesnt really matter unless it isnt worth it, like saying underclocked CPU/memory with be worse than 4g at the speeds I have, or will it degrade again =(.

    I think some one of the other 4 stick memory problem got things resolved ,it should be in the first 2 pages of posts. I cant think of anything else non bios related.
    Have you actually reinstalled vista tho?
    When it crashes it puts the board(my board anyway into a reboot loop).Only way to stop it sometimes is to turn off the psu for 1 min or so and then turn the pc on again.
    Clear out all the old memory error dump reports from the hdd,before each new attempt.
    Try saving the bios setting that works with 2 sticks of ram then load and save optimum defaults then put in the 4 sticksand try loading the bios that worked with just 2?

    Then again maybe its the ram :(

    Have you tried mixing the matched pairs ie one stick from pair A and one stick from pair B to see if they worked in 2x2G.
    There is a thread with some unhappy campers here too..
    http://forums.tweaktown.com/f69/ep45...cks-ram-30024/

    and I have seen some people unhappy with the gskills the 8500 ones.
    Ive posted before that Ive run 4 sticks(2 different brands) ok and even clocked them a little ,but I dont know of a specific soln,Just check thru the posts and maybe Lsd or someone will get back to u with settings to try,
    Or return the memory,I dont suppose they do a 4 stick kit guaranteed to work together for the same price as 2 ,2 stick kits.

    Default Re: 8g memory stability issues with EP45-UD3P

    I think some one of the other 4 stick memory problem got things resolved ,it should be in the first 2 pages of posts. I cant think of anything else non bios related.
    Have you actually reinstalled vista tho? No I havent. Thought about it but the whole bios not showing post or PCI doesnt seem like it would be an OS problem yet it doesnt happen with 4g of RAM.

    When it crashes it puts the board(my board anyway into a reboot loop).Only way to stop it sometimes is to turn off the psu for 1 min or so and then turn the pc on again. I read some on this but on the old board it always worked for a day usually before the next crash. The new board booted up once or twice in between crashes.

    Clear out all the old memory error dump reports from the hdd,before each new attempt. To be honest I havent done this.

    Try saving the bios setting that works with 2 sticks of ram then load and save optimum defaults then put in the 4 sticksand try loading the bios that worked with just 2? I did not try this yet. I used the 4 stick optimized settings with the 2 sticks at a time and it worked.

    Then again maybe its the ram :( To be honest this is what I was wanting it to be cause its easy and cheap. Newegg with not RMa these as it is passed 30 days. Havent checked with GSkill but they seem stable at 2 sticks. Thought about trying another brand but than again, is it worth it?

    Have you tried mixing the matched pairs ie one stick from pair A and one stick from pair B to see if they worked in 2x2G. No, have to try fiddling some tonight.

    There is a thread with some unhappy campers here too..
    EP45-UD3R won't run 2 sticks of ramYeah I have read through there. Still whats weird is I can run two sticks and I can run them dual channel.

    and I have seen some people unhappy with the gskills the 8500 ones.
    Ive posted before that Ive run 4 sticks(2 different brands) ok and even clocked them a little ,but I dont know of a specific soln,Just check thru the posts and maybe Lsd or someone will get back to u with settings to try, Havent seen the ones about issues with 8500 GSkill =(

    Or return the memory,I dont suppose they do a 4 stick kit guaranteed to work together for the same price as 2 ,2 stick kits. Again, Not by Newegg and I havent seen many computer part manufacturers besides EVGA worth a crap =(. Havent tried GSkill YET.

    Still find it weird that it effects both crashes and my bios screen. Plus it worked fine for a little while. Starting to think if there is a performance gain to be made, it might not be worth trying new memory or what not unless it is a setting issue.

    Well I did talk to a buddy that has an R version of this board and he does know a lot more than I do about this. His rig is running 8g at 1066 with his CPU running at 4gig (ofcoarse none of his settings are on auto lol) I hope you can post up some settings for me that work. He agreed with everything you said so far except he said I might try the things you said plus run the memory at 800mhz and see if its stable then push it to 1066 and up my settings.

    Dont think I mentioned this before but I did notice that the memory says on it that the voltage is 2.0-2.1 while the website said 2.0. I guess I should have messed with some of this stuff up front and didnt think 1066 was really OCing for DDR2. Guess I will learn the hard way but seriously anyone know why it would work great for like a month and then just go to crap?

    Maybe you could do some kind of deal/with Gskill even for a guaranteed 4 stick set like Newegg.com - G.SKILL 8GB &#40;4 x 2GB&#41; 240-Pin DDR2 SDRAM DDR2 1100 &#40;PC2 8800&#41; Quad Kit Desktop Memory - Desktop Memory
