    Exclamation EP45-ud3r

    hi,

    I just recently got new CPU ram and mobo for my system. I got a E7400, 2gb OCZ SLI ready 1066 ram, and ep45-ud3r mobo. I got this hoping for the clock speeds that i see other people running wolfdale chips at. I wanted to get to 4ghz But can only get stable at 3.6ghz. No matter what try. But thats no the huge deal because 3.6ghz is still really good imo. So i ran occt for 1hr stable and prime95 for 20hrs no problem. So i assume it would be stable. But when i try to play any game (cod:waw gta 4 or battlefield 2142) i get Gfx issues. Textures disapear, and locks the game up but not the system vent still works and i cant ctrl alt delete out of the game. I have also after this started i put bios settings to oopitimized defaults with no luck.

    After all day of trying to solve the issue. I think i might know what it is but cant find any info on it. The CPU power on this mobo is an eight pin. This i think is a problem because my PSU has two 12v rails and each 4pin power connecter it has are on seperate 12v rails. So what i am thinking is that now that my cpu/mobo is takeing up more power on the 12v rails that my gpu is not getting the juice it needs. Nvida says its suppost to have 26a on one 12v rail.

    specs
    2 hds both 7200 rpm
    2 dvd burners
    E7400
    gigabyte ep45-ud3r
    2ghz OCZ SLI ready 1066
    8800gt
    freezer 7 pro cpu cooler
    PSU BFG power supply - 650 Watt Power Equipment reviews - CNET Reviews

    I couldnt find a review site that shows what rails that the PSU has but it has two 12v rails at 20a each.

    Thanks for any help in advance. I am not sure i am on the wrong or the right track. hehe

    Fill out one of the BIOS settings templates you see floating around in every other thread here please. We can't help you unless we've got some solid information.

    This is what i have it at as of right now. But the clocks don't effect the way my GFX freeze up when gaming. I set everything to optimized defaults and games will still artifact within 1hr. the closest i have got to 4ghz was 9x 445fsb cpu vcore 1.40 volts CPU Termination volts up to 1.32 mch core at 1.30v i can get to windows loading screen but freezes when loading. I dont need an overclock tbh this cpu is alot faster then my old 6000+ x2. I just need my games to stop freezing once thats fixed i can try for higher clocks.

    Is it just me or does anyone else think my PSU is to blame.

    Unhappy Re: EP45-ud3r

    update: Running at optimized defaults just change ram volts to 2.1 and timings to 5-5-5-15.

    I have some videos of what it is doing and thought i would post them to see if anyone has any ideas.

    Update: Same settings as above but i switched the GFX card from my 8800gt to my roommates 8800gts. They are similar cards and run about the same. I get the same artifacts/textures as before. I have the side of the case open and card is only running 70c.

    Please post me a image of this program running so I can see what some of those Auto's are giving you. They all look ok, meaning nothing to bad off, I just wanted to really check what tRD Auto is using >>>
    Tweakers.fr ~ Memset


    This is 2x1GB right? If so you can and maybe should leave MCH Voltage to Auto

    Yes, I agree kinda. 20A Rail is pretty weak (And keep in mind that is a MAX Rating, not normal), and if you only have 2 that really is bad as your whole system would only have 14 if that after your GFX card. Now I am not saying that PSU is to blame for sure, or that it is bad or not enough. Just commenting on the rails you mentioned

    Can you test your buddies PSU in your system? I would assume since he has a similar card he may have a better PSU Right?

    Unfortunately he doesn't have a better PSU. His PSU doesn't even have 8 pin CPU power. After i discovered this problem i have stopped all attempts to overclock currently MCH is on auto. And yes my ram is 2x 1gb. Newegg.com - OCZ SLI-Ready Edition 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500) Dual Channel Kit Desktop Memory - Desktop Memory

    I have not ran memtest but if you think it may be an issue i guess i am going to go and download it and see if it comes back clean.

    Post Re: EP45-ud3r

    Lots of testing today!!! Found that it has to do something with the RAM. 1st I ran memtest86 it passed. Then i switched the my CPU with my roommates E8400 problem still there. After 20 mins of playing COD:WAW. Then to just make sure it wasnt the ram i switched it out for two sticks of old RAM 2x1ghz 667mhz ddr2 cheap ram. Ran the ram on auto volts and timmings and played over half the day no problem at all. So is my mobo just not liking the ram or should i leave the volts alone or is there a setting somewhere that is whack see above post for timings and volts.

    I think unless someone thinks different I am just goting to get different RAM and RMA the RAM i do have. Is there any RAM that i should get i should prob spend a little more money then 30 bucks. Does gigabyte have a list of RAM that is known to work well with this mobo.

    Thanks for your help i think i will be back here later when i get some stable RAM for tweaks on how to get a stable overclock above 3.6ghz.

    The simplest thing to try if you think its a system memory problem is to up the ram voltage?
    On the screenie u posted it shows you set v2 at 2.1 yet your hw monitor is showing it goes to a minimum of 2.06.
    I get voltage drop on my memory,I know its very overclocked but if the voltage i set in bios was actually what it received I wouldnt need to set it that high .
    Your memory says 2.1 to 2.3 volts yeh?
    Perhaps putting in 2.2 in bios would help.
    Id like to run my components at the same speed at lower voltages,but I cant find any posts showing them doing that or settings in bios.
