Hi
I just got a Gigabyte P35-DS3R, an E6750 and a Thermalright Ultra120+Scythe sflex fan. I can reach around 3200mhz on the stock voltage, without having to mess with timings or anything else in the Bios (latest F7 revision).
I take it to 3.3ghz but i need to increase the voltage to 1.375v.
Anything beyond that and i need to add some serious voltages all around to get the damn thing stable. My mobo has a bad vcoore drop also btw, it drops like 0.5-0.7v when i hit it with Orthos.
Anyway, to get ~3550mhz (444 x 8) stable i have to set my latencies to 5,5,5,15, add +0.2v on both the Southbridge and the Northbridge and set the voltage in the Bios to 1.518v (this drops to around 1.44 at full load). The temps are fine.
Now i'm running at 3656Mhz (457 x 8), 5,5,5,15; +0.3v on NB and SB and, get this, 1.59v on the CPU
When i hit it with Orthos it drops to around 1.52v but at least it's stable. Temps never go beyond 55-57 deg. Celsius (with Core Temp, 100deg tjunction) and it idles at around 25/31 (1stCore/2ndCore).
My question is... is this a safe thing to use even if it doesn't pass 60deg C? I've heard people say that i can lower the life of the CPU to 6 months or something along those line.
Also, why the crazy vcore? I know people who are getting 3.6ghz 3.75v (0,25 more then stock). Is it just my luck catching a bad chip who needs loads of voltage to get anywhere?
Anything beyond 3656Mhz and windows doesn't want to load. No matter what vcore i set. I haven't increased the PCI-ex voltage btw but doing it makes no difference in stability and max cpu speed.
I was really hoping to hit 3.8-4.0ghz with this chip. That's why i chose it over the Q6600
