hi, please could you help me ? i've been trying for a couple of weeks to get a stable overclock, but cant, i've only got it stable @ 2.8ghz, i go into forums with little or no sucess. (i'm new to overclocking). i have a asus p5n32-sli plus with 1502 bios, core 2 duo E6750 with artic freezer pro hsf, 2gig corsair xms2 pc2-6400 @ 5-5-5-12 1.9v, nvidia geforce 9600 gso 1 gig and vista premium 32bit sp1. im told that my system should be capable of at least a stable 3.8ghz overclock. i would like a 3.4ghz as i cant afford to upgrade just yet. any help i would be gratful
I used to have the same setup, I killed the motherboard by overclocking the CPU. I upped the frequency, it seemed stable, went to the pub leaving the PC folding, came home and it had bluescreened and refused to boot. After getting a replacement, which then wasn't stable even at std clocks, it would crash under heavy load I managed to get a Abit IP35 pro as a replacement. CPU is currently at only 3GHz because too much vDroop. From my experience I'd recommend staying at what you have already.
There's no guarantee with overclocking, even master OC'ers can't do anything with a bad chip. Don't be lured into the trap of keep overvolting stuff. I got close to killing a chip by getting the "I must get to the next hurdle" blinkers on, fortunately it lasted.
the chips not the prob i've now tried it in a msi neo 3 board and it runs perfect @ 3.36ghz, tested with prime95 for 4 and a bit hours and sweet ! i think i'll have to get this board from a friend
Thought I'd pipe in here, also had the same board running an E6600 year or 2 back, couldnt get it stable above 2.7Ghz, went from that to a P5K and managed 3.5Ghz. That board must just be a bit duff for overclocking in general by the looks of things.
i had a p5n32e -sli a few years back and it was turd at overclocking, the 680i chipset on the whole was very unpredictable, some would massively overclock, others would chew on your memory and make you buy new sticks...i think you summed up your problem in your response, in another board the cpu overclocked, in this board it does not and that right there is your limiting factor. when you are overclocking so many things are affected that any one of them can make an overclock unstable, and imo that board is a nightmare so i'd just live with it, and scour the forums for a cheaper upgrade when someone sells and intel chipset based board like p45 as they generally overclock alot better. thats my ten cents worth, and i know you asked for help and i just gave my opine so i do apologize but krikkit has already told you not to go crazy with the overvolting and thats all you can do when it isnt stable, more volts more volts more volts but that doesnt always work. peace fatman
IMHO, looks like your ram could be undervolted a bit. If you volt it higher check the spec's and see what the manufacture says for a setting. Like people have said already though, be aware of your volts and such. Also want to point out that a sync can be more useful then cpu speeds. An odd sync will make the system perform like crap, but a decent ratio will provide quite good performance, even at slower speeds (I have my Q6600 sitting at 3.01 ghz and its speedy as hell under a 3:2 ratio). When I OC'ed my board (evga 680i) it was recommended to pop the heatsinks on the top of the board and replace the thermal paste with something better too. So even a bit of research on your board alone could provide details that others have delved into, especially in the OC world. Hope that helps some
that's good advice outlaw on re-doing the tim on the mosfets.. the 680i is very picky on it's voltages- you can't auto volt anything like intel chipsets it's not that it can't overclock.. it does very well despite having fsb holes- you just have to know what your doing right down to the northbridge/mcp voltages.. too much or too little and you get instability memory it's not recommended you go over 2.1v on that board either- it will eat it.. there's a vdroop pencil mod if you want to look that up and it seems intel chips are ok with the spike it creates (vdroop is there by design)
I concur, had this board for a bit and when and if you want 1.9v you really need to dial in 2.0v. But overall its a poor overclocker.
