Hey guys, I am just wondering if anyone comes onto this post and happens to have an e6750 running @ 3.2GHz, if they could post their voltages and whatnot that they were able to get it running stable at. I have aftermarket cooling and really good ram so I know that hardware is not the issue, but settings.
I can get my e6750 up to 3.0 Ghz, and run my RAM at 750Mhz for a 1:1 ratio, but ideally, since I have RAM that is going to be great for a few years (1066 G.Skill), I would like to run my system at 3.2GHz with my RAM at 800Mhz for a 1:1 ratio and a better increase in overall performance.
The problem is that no matter what I do I cannot get 3.2 stable. I have tried upping and downing voltages, and the longest I got it to last at that FSB rate was 30 minutes, but it did not fail due to CPU heat, so I am wondering if I need to up my NB/SB voltages.
I got it stable for thirty minutes @:
3.2 Ghz (400*8) @ 1.29/1.312 Vcore Voltage
RAM @ 800 Mhz, tried both 4-4-4-12 and 4-3-3-10 @ 1.8-1.9v (can run it stable at this voltage @ 750MHz w/ 4-3-3-10 timings, upped it to 2.0v for 800 MHz since I increased the clock and kept the tighter timings).
NB voltage set to 1.35-1.4(1.25 stock)
SB stock voltage (1.5 stock)
I ran a 20 minute Orthos Small FFT test, it was fine and temps peaked at 58 C, but after about ten to fifteen minutes of Wow once I finished the test, I had a total system lockup and had to reset CMOS.
At that point I put everything back to stable @:
3.0 GHz (375*8) @ stock vcore of 1.24, stable @ 57 C full load.
RAM @ 750 MHz (4-3-3-10-23-2t @ 1.9v)
NB stock voltage
SB stock voltage
I will keep this setup for now, just need to know what other people with similar setups are setting their voltages to for NB/SB and CPU Vcore so I can get an idea of what I need to adjust.
