My spec : -

P55 GD65
Hey guys, I tried some overclocking based on this guide. Note: this is the first time for me to overclock, so please forgive my noobness
So as I tried yesterday, I changed my multiplier to x12 and gradually increasing my bclk to isolate my highest bclk. But apparently the only stable bclk I can reach is only 200 x 12 = 2400 MHZ which is lower than the stock spec...
When I tried increasing the bclk beyond 200 it fails to boot with the "Overclocking Failed! message". I then tried increasing the VTT with a small amount and still it failed. I tried gradually increasing both bclk and VTT but still fails. However, there are occasions of me successfully booting in to windows, but as I initiate stress test (prim95) the whole system hangs in less than 5 secs. No BSOD, just freezes.
So now I'm clueless of the multiplier, as mentioned in the above guide the multiplier is set to 12 to isolate the highest reachable bclk. But no mention of other multiplier. So my question to you guys is, can I use other multiplier? I did some googling and found out the stability offered by x20 multiplier is rubbish ?
added note : my VTT is 1.2 (+/-)
hey there, the purpose of lowering the multiplier to x12 is to find the max blck, as u found ur max bclk, for ur case, its should be 200, next thing u can try is lower down the max blck, say 180 then start playing with the multiplier and the vcore, to find the max cpu freq, cpu freq = bclk x multiplier... if u just want to find the max freq, u shd lower down ur mem multiplier to x8 to avoid instability caused by the ram speed... btw the guide u are reading is a very good guide.... i5 750 Lynn

as mention in the guide,
VTT = the voltage supply to the IMC (internal memory controller)
vcore = cpu voltage that used to stabilise the cpu frequency
all mobo manufacturer using diff naming for the voltages... hope this helps =)
