e2180 headaches PLEASE HELP

post #1 of 33
Thread Starter 
Hello friends.... I am trying to get my e2180 to 3ghz stable. I achieved this last evening, and then it failed to boot this morning. I am using a biostar tp35d2-a7, with 4 gb (2x2) of a-data ddr2 800. I am running 333x9, ram at 1:1, (666). It ran prime for an hour with max temp of 61C. I use a rosewill cooler with a 92mm fan running at 2400rpm. I have bumped the vcore slightly. Ram timings are 5-5-5-15. Why would it all of the sudden not boot??? I installed everest last night, but I didnt mess with a single setting. Could this somehow have messed me up?

From my experience, I needed 1.425v to get to 3.0ghz. Maybe give it a bit more voltage and see what happens.
Also are you saying the RAM is running underclocked? - i.e. running at ddr2 667 rather than ddr2 800.

Yeah, I guess they are running underclocked. I am new to DDR2, and my board doesnt seem to have a manual memory divider in bios. I am thinking also of trying to run 350x8 for 2800. Do you think I will have better luck with higher fsb and lower mult?

It depends, as far as the multi I had more luck with 10x, but others find lower multis help, as that is a value motherboard it may not like the higher FSB. You'll just have to experiment, my guess would be you need a tad more vcore.

Thanks for the help.....I guess I will bump the vcore some more. I still am scratching my head at why it all of the sudden doesnt want to boot nicely. I did have one more thing....I noticed the NB heatsink was a little loose. The springs on the clips offer very little tension, and if I lifted slightly, it would come off of the board. I plan on putting new compound on there, and I already have a 40mm blowing right on it, but could unseating/reseating it have somehow lessened the heat dissipation enough to not let me boot at 3ghz as I did before???

I doubt it. Possibly, on some mobos when you do a cold boot (left off for more than 3hours or so) the CPU may need a little more voltage to cover for the voltage regulators not being warmed up (efficienntly). Reseating the NB heatsink would be a good idea anyway IMO but be careful.

That makes perfect sense. I will try giving more vcore to "jumpstart" it and try backing down and rebooting to see if indeed this is my issue. I will post results later. After that, I need to figure out those stupid smartfan settings. Speedfan misreads one of my sensors at 127C, making fan setup through speedfan impossible. Oh well..... thanks again for all the help!!!

No problem. Smartfan in the BIOS is usually better anyway. My system is near silent when idling, but like a turbine under stress

I have my e2180 @ 3.2GHz running stable at 1.375 vcore, see sig for system specs...

Are you sure the cpu is your problem? I know with my build I had to up my memory voltage +0.1 to even POST with more than 1 stick of RAM, and then another up again to 2.1v to pass Orthos tests at my O/C settings. I'm using 400 FSB with 8x multi = 3200MHz, RAM at 1:1 5-5-5-18 rated at stock 800 speed. If I try to manually set the timing to Corsair's specs of 4-4-4-12 I have memory errors during stress tests. Keep in mind when you change the multiplier you can then play around with different memory ratios, and I think it is a good idea to keep the RAM running as close to stock speed as possible. I can confirm that sometimes one of my computers has that cold boot issue where it starts, then stops, then starts again if it has been off for a few hours.

Anyway, best things to try in my opinion are:

Upping CPU VID a bit and see if you can POST properly, OR...
Lower your multiplier and up the FSB a bit and then check stability, OR...
Boot up with only 1 stick of RAM, then up your memory voltage, put the rest back in and try again.

Sometimes everything SEEMS to run fine, and you think you are stable, but actually you are anything but and it just takes some stress before you realize it.

Hope that helps some. Good luck!

So, what options do you have in your BIOS--are you able to increase the FSB voltage and the VDIMM voltage? I know your RAM is running under stock speeds, but go in and make sure it's getting the correct voltage (could be an issue, but I doubt it...). Also, did you go through and find your max stable FSB by lowering the CPU multi to it's lowest and ratcheting through the FSB's, 5 or so at a time? Could be you're above your board's FSB limit, or near a FSB hole...

Other than that, I'm out of ideas... How old is your 2180--is it from one of the newer batches, 'cause supposedly they don't OC to/past 3GHz as easily as the older ones from a few months ago. Well, hopefully you get things squared away--let us know if you try anything else.

Is this on your DS3L board (or any DS3)? 'Cause I believe that to be a problem with Gigabyte's BIOS and a CPU-placement sensor on the board--mine does the same thing when not at stock settings for some reason--when I start or restart the machine, it powers on for a second or two with the fans running, powers off, then powers back on as normal (not like it's the bios protection feature because all settings are retained). I found a thread on this somewhere...maybe I'll look it up again. Don't really want to update my BIOS to get rid of it though...
