Hey everyone, I used to do some overclocking years ago but then moved onto laptops and forgot all about it, recently I built myself a server for the house, it was really just a file server/torrent downloader so I just used the cheapest stuff I could find, lucky enough most of it turned out to be pretty good.
Intel Celeron E3300 chip
Gigabyte G31m-es2l (Reason I went for this board was it was the cheapest board with gigabit lan on it.
Cheap case (£10 although good quality cases we use all the time in work, has room for 120mm fan front and back and has a air duct on the side panel which sits over cpu, this can be changed for an 80mm fan, it is also very sturdy with no sharp edges and does not rattle.
Cheap psu, evo labs 600watt psu, cost £15 and has a 120mm fan
2 x 1GBTeam PC800 memory
When I first got it I had a play about with overclocking, all I did was up the FSB to 320, locked the pci-e bus at 100, changed the ram divider to 2.66 (I think) and leave the vcore at stock (auto controlled?) this turned my 2.5ghz intel celeron into a 4ghz chip which ran very nicely, temperatures where very good even with the stock cooler, I tried booting at 4.3ghz and it worked but bluescreened straight away, this was on stock vcore, I didn't dare change this at that point because of the cooling.
Yesterday I managed to get hold of an all copper zalman cooler which looks to be a very nice cooler, I got that mounted on last night with some AS5 paste, I also re did the northbridge heatsink with AS5 just incase.
The paste hasnt properly cured yet so temperatures have only went down by about 5c or so.
Anyway, now I have the new cooling I want to try and get more out of the chip so last night I had a little play and I managed to get it running at 4.25ghz stable with a vcore setting of 1.45 in the bios, but the bios shows it as 1.39v when I check the system monitor.
The machine will not boot if I try any more, I have tried dropping the multiplier to see if the motherboard/ram could handle the FSB and it wouldnt post, even at a much slower clock speed than 4ghz. I also tried dropping the FSB back a bit and changing the ram divider and then ran ram pefectly fine at 1066mhz.
Any help would be appreciated, I think I might need to up the vcore some more but I want to know what a safe setting is although to be honest I am not all that bothered with damaging the chip as it is so cheap (£30 through our suppliers in work)
I would love more out of the chip but I know a 70% overclock is already very nice.
Also for those doubting its performance because its a celeron (dual core), it does a super PI 1M in 15.834s which I understand is pretty good it is also able to transcode 1080p mkv files with 6 channel audio to my PS3 without any buffering and can do scene selection pretty well although the scene selection not as smooth as I would like.
Current overclock

Old vs New (Yes I managd 4ghz on that stock cooler with stock vcore)
