    Runs up to 44C when doing the ram tests. Normally under 30C. Zen heatsink with MX-2 paste. Motherboard sensor 46C. External room ~23C

    The only test I'm seeing failures on now is test 8. Not all the time but some times. Not just one chip, sometimes high, sometimes low. Any thoughts on what that might say?


    Edit: 44 was the IT9718F temperature. The cpu0/1 temps could have been 3-6C higher than that.

    Well, just a bit more tweaking I would assume. Did you raise them all one and then go back in lowering one at a time and test after each? I know it may take some time but that is the better way to test things.

    I didn't raise anything ... basically the most conservative combination of the gb auto settings and your settings as per the previous page.

    After it had been off for about 3 hours I restarted it and it crashed ... bios autofallback to F1 again. So I dropped it back to 2G of ram with the standard auto settings. And this morning it started fine. Reloaded F3. Will stay on auto and see if it boots fine tomorrow with 2G.

    At the moment my only conclusion is that the Gigabyte EP35-DS4 won't reliably support 4G of Geil 1G ram sticks no matter how conservative the settings. Would the ASUS boards be better? A new MB would be cheaper than buying another 4G of a different kind of ram.

    Do you have a fan on your NB? If not, have you at least redone the thermal paste? I would try that, I always do all my new boards. And actually my DS4 was partially covered, with WAY to much paste.

    I say that because with 4x1 there is a lot of stress on the NB.

    Post what settings you use that fail for the 4x1 combo just so I can see what we are speaking of here. And how hot is your NB at load (Motherboard on some temp apps). If you do not have any easytune will show you, it is system temp in that

    Lsd,

    The killing thing for me is that with 4x1 I get these failure startups that force a reload of the original bios. My system temp reached 46C when I was doing the ram test. That means it isn't worth trying to tune it or cool anything ... because I get a "complete failure" when its all around the 20C range (ambient this morning was probably about 17C).

    46C is hot!!! My NB/System temp is 30 Idle and 34-36 Load. But yeah I do see your point, post what you are trying setting wise and lemme see

    Just so you know I am being honest

    34C @ 13 Hours load >>>

    Thats an impressively low system temperature Lsd. Without modifying the structure of my fans I won't get my system sensor that cool (assuming its down by my graphics card which is the hottest area in the system). My cpu beats yours though

    My external cpu temp is 23 normally and reached 44 when running at 100% for 5 minutes plus. The internal cpu temp is 3-6C above the external temp. I located the Northbridge itself by the cpu and it's benefiting from my cpu fan. I can rest my finger on the Northbridge heatsink for as long as I want and although it feels warm it doesn't feel hot so I'm guessing its fine.

    My settings with 4G of ram in the system were the conservative settings from this post:
    http://forums.tweaktown.com/f69/ep35...tml#post251676

    It ran well although I still got the odd error in test 8. It had cold started fine a couple of times but yesterday it sucked it big time ... doing the bios reload setup.

    So today I ran with 2G of ram in the Auto settings (both pairs of sticks run with auto or above conservative settings and show NO memory errors if run alone). I will turn the system off soon and turn it on again to see if it cold starts ok. Then I'll leave it off overnight to see if the same applies.

    Thanks for your time on this. If there isn't an "easy" solution I shall use 2 of the sticks in another system thats only got 1G currently and wait until the next drop in prices to buy a couple of 2G 1066 sticks.
    John

    Ya, Kinda HOT though on the Cores, but I only have a Zalman9700. Water parts on the way!!!! Yeah!!!! Nothing special on the NB cept all new TX-2 on mosfets and NB/SB

    Well that does sound cool, since you can put your finger on there. But kinda is still not very convincing being you said 46C that is almost 120F pretty hot.

    Post those settings you are actually using. Conservative can mean a few things tight or loose depending on how you look at things...... and you said you changed a few... So I just wanted to see. When ya get the chance, no biggie

    Ahh no problem about my time, Im here to help when and if I can.

    See you tomorrow I got to get out of here for the night, good luck on things
