Hey im having a problem with my new Intel Core 2 Duo e6750 CPU which has got my brain tied in knots
In the past i've overclocked on the same motherboard (Biostar GF7050V-M7) with an Intel Core 2 Duo e4500. I reached a stable core speed of 3.2GHz (up from 2.2GHz) and the Intel Core 2 Duo e2200 prior to the e4500 reached 3.0GHz fine aswell (im slowly upgrading the CPU over time, aiming for q6600 in a couple of months)
I figured to replace my e4500 (now flogged) with the e6750 because it had a larger L2 cache (4MB instead of 2MB) and its FSB was a default 1333MHz rather than the 800MHz the e4500 had. I've also read plenty of reports of the e6750 reaching 3.6GHz, even 3.92 GHz with upped voltages so im in a pickle.
If i increase the frequency of my CPU by changing the FSB it can boot at 2.8GHz but no more
I've also noticed on CPUZ that the details are incorrect - says my multiplier is 6x (when its set at 8x) and therefore the frequency is only 2GHz?! The voltage is only 0.992V so im getting increasingly worried now.
What I've Tried
To tackle the problem I have messed around with the voltages (it only uses percentages of 100, 102, 104 and 106% so thats difficult to judge rather than say, setting it at 1.4V for a 3.8GHz clock but without success. I've also recently bought a 700watt EZcool powersupply.
I was wondering whether my motherboard has finally decided to throw in the towel or whether there are some settings im overlooking which is stopping me from overclocking further?
thanks in advance
