Help!! New e8400 keeps locking up on OC Tags: Overclocking Last response: February 4, 2008 3:24 AM in Overclocking Share davidc February 3, 2008 5:05:22 PM e8400 Abit IP35-Pro Crucial Ballistix 4GB (4 x 1GB) DDR2 800 (PC2 6400) Tuniq Tower 120 Vista 64 bit home premium Running latest bios. This is my 1st full-system overclock and I'm not sure what to try next. My computer keeps locking up without any indication anywhere else that something is wrong: Running at 425x9=3825Mhz vcore=1.35v Memory: 5-5-5-15 at 2.2v When I run Prime95, it locks up after only a couple of minutes without any errors. The temp on the CPU is 48c. Any ideas what to try next? Any advice is greatly appreciated. More about : e8400 locking steeda February 3, 2008 5:56:57 PM go with more vcore voltage, its either your cpu or your memory, dont go above 1.5v in cpuz and no more than 2.1-2.2v on your memory in your bios davidc February 3, 2008 6:17:39 PM Is that 1.5v in cpuz load or no load?

Get the answer jimmmm February 3, 2008 8:41:00 PM What our your CPU core temps davidc February 3, 2008 8:50:17 PM Peaked at only 48c full load. Definitely shouldn't be heat. The thing I don't get is why a lockup? No Prime95 error, high temps, etc. Could it be a Vista x64 thing? Evilonigiri February 3, 2008 9:22:30 PM I say ram. Stress test using Prime95's blend test for 8hours. If it fails, your ram is unstable. davidc February 3, 2008 10:02:10 PM What settings? Lock it in at 2.2v 5-5-5-15? It's rated 2.2v 4-4-4-12. The timing table shows: 400MHz 4-4-4-12-24 2T 2.2v 500MHz 5-5-5-15 30 2T 2.2v Evilonigiri February 3, 2008 10:04:48 PM Do 5-5-5-15 2.0V. Just because it says 2.2V, that doesn't mean you should use it at 2.2V. If it fails, reduce or increase voltages. davidc February 3, 2008 10:19:19 PM I thought the theory was start high and lower if you can. Why use 2.0v instead of 2.2v? BTW, thanks for the help Evilonigiri February 3, 2008 10:23:49 PM davidc said:I thought the theory was start high and lower if you can. Why use 2.0v instead of 2.2v? BTW, thanks for the help Sure, anytime. RAM is picky about the voltages. Too much voltage will make the RAM unstable. steeda February 4, 2008 3:24:41 AM he is totally right, my memory is rated at 2.3v but i only do 2.1v, everything is stable, if i go above that, my memory freeks out on me sometimes, and definitely unstable at times. I would do the 2.0 and even 2.1 but never go above 2.2v Can't find your answer ? Ask ! Publish Related resources: ForumOverclocking E8400 on Asus P5G41C-M LX help !!!
