Im trying to find a stable overclock for my xeon e3110 without increasing any voltage. just wondering what other people have gotten on stock voltages. im not sure if the xeon e3110 has a different voltage but on idle its 1.136v and under full load in prime95 its 1.192v. currently at 3.555ghz 395fsb (1580 rated) only tested in prime 95 for 30 mins but will test more tomorrow.

i know for a fact i cant keep a rated fsb of 1590 stable at stock voltages.

edit: intel speedstep is enabled so it goes down to 2370mhz in idle.

max temps with prime95 ffts is 56 core0 51 core1 not much different than at 3.4ghz which i had previously been using for months.

I have no idea what the hell you are trying to ask.

Im asking how high other people with a c2d 8400 or xeon e3110 have gotten with overclocks on stock voltages.

what IS a xeon e3110 lol? i thought it was some obscure C2D when i read the thread title... how many cores, stock frequency and what cooler have you got??

xeon e3110 is practically identical in every respect save name to the e8400. I got my e8400 (e0 stepping) stable at 3.8ghz without bumping the vcore. My next try, was 4.0ghz and that required a very slight vcore increase. I suspect that I could probably push it a little higher than 3.8 without bumping voltage. Intel's rated specs go up to 1.3625v. As long as you don't exceed that (and keep temps low), you should be fine.

yeah i hit a wall when i close in on 3.6ghz on stock voltages. not sure what stepping i have. cpuid says stepping 6 then revision c0.

ive had very little luck overclocking when increasing voltage was necessary. 3.6ghz wasnt even stable with a 0.0875 v increase on cpu core. which is like 6 steps of voltage. (i think it was around 1.2-1.25v total). increased heat by alot but wasnt even stable for 30 mins in p95

the only difference between e8400 and xeon e3110 is the voltage range vid:
E3110 vid is 1.225V-0.956V
e8400 is 0.85V – 1.3625V


so i guess i cant raise the voltage as high as the 8400 on mine.

There seems to be confusion on what VID and ABSOLUTE MAX voltages are:

VID: Is the voltage range that Intel gives it's CPUs to operate at stock speeds. This is the voltage that the BIOS uses to boot the CPU at stock.

ABSOLUTE MAX VOLTAGE: Max voltage is NOT the VID range given in the Intel CPU Finder.

For 65nm: 1.5v.
For 45nm: 1.45v

ABSOLUTE MAX is the point where permanent damage to the CPU can happen.

Shadow, would you mind posing your source for those numbers? I've heard of lots of folks going upwards of 1.45v on their wolfdales. Thing is, I think that if you exceed the 1.3625v spec you void your warranty.

Even still, hitting vcores that high, you're bound to run into major heat issues if you're on air. I was hitting 62c on 1.344v (after vdroop at load) at 4.27 ghz (474x9) with my e8400 (e0). I'm using the second gen Thermaltake Big Typhoon and AS5.
