Regarding the maximum VCore you can feed the 45nm cpu's for 24/7 usage :
Dualcore : 1.325V max
Quadcore : 1.375V max

In a normal PC used to play, surfing internet, doing some Office, etc., you can push a little more the voltages.
I also like to play safe with voltages.
My E3110(Q807A091) runs @4,5G with 1,4V stable.Temps under full prime max 54°C (NV120 Premium cooling)
I only run my machine about 3-5hours a day.Thus I have heared Xeons can take a little more vcore than e.g. E8400 due to the longer binning.Is this correct and is 1,4V for my low per day usage okay?
Read what I wrote a couple of posts above.
I'm not making this up, this info came from someone at Intel.
yea i sure read your post.However i ain't running 24/7 only 3-5hrs/day and you only wrote about 45nm cpus.Is it now true or not that the "longer binned" Xeon cpus can take a little more vcore?
I don't think that, because they're a bit better binned than the E8400, that they can take more voltage for a longer period of time compared to the E8400.
It applies to all 45nm cpu's, being it Wolfdales or Yorkfileds.
Maybe that in your case, as you'll be running it 3-5 hours a day, you might go a little over the recommended 1.325V, but I personally wouldn't let it run at 1.4V.
But that's my opinion. :)
Here's 4.2 on a Q807.

Memory is 1:1, 5-5-5-15-54
Unfortunately, my board's NB HS height will not allow me to orient the HSF (xigmatek HDT-1283) so that air is exhausted out of the back of the case.
I'll be replacing that with this...

Then turning the cooler to blow out the back of the case instead of @ the powersupply. Should net at least a few degrees C cooler @ these settings.
Case I have is this...

Why can the Quad take more V than the Dual? A Quad is just 2xWolfdale DIE's, so why are the Quad's rated at higher Volt?Quote:

Batch is: Q805A165
which mobo mate ?
Foxconn Mars ;)
Good day... some update for yah ^_^

what best batch for E3110?
my batch Q746A541 but in 4.5Ghz is need high Vcore
q807 looks like a good one based on the posts here. Mine is still new in the box so i can't say yet though. :cool:Quote:

Look at my list mate to search for a good batch :

Hey new here just was checking how you guys did with your overclocks and all.
I got a q745a784 batch of xeon e3110 and it isn't all that good. I need like 1.46v in bios * cpu z showing 1.4l load to get 4ghz stable at 500 x 8 *ram synched * Load temps like 60c (52 real temp). Its good enough for me and i am running this 24/7.
But I am wondering what are the chances that it could affect the other components of my system if the chip decide to go in say 6 months? *all the mobo voltages in the green* ^ I don't really plan on it lasting much longer then that, as it is exceeding the 1.25v by a bit :rolleyes:
Yep pretty bad batch mate, damn unlucky plus the bad PWM of the 780i also doesn't help much here.... 2 other results of the same batchQuote:

at default idle temps are very good (+6/7 over ambient). I'm a bit worried on the difference of 8-9c between the two cores. Somebody says thats normal. The TRUE is well seated.
I had one of the first 8400 produced that has 20° of difference between the two cores.Quote:

Cool* thanks :)
[* I wish it was, 30°C here]
mine needs high 1.4's set in bios to get anywhere over 4G's also. just built this xeon with gigabyte ep35c-ds3r and 2x patriot ddr3 1866to see how the board would handle ddr3. doesn't get a tick over 1600, but still has impressive numbers throughout the range of dividers and is much cheaper than most other ddr3 boards. threw box away and didn't save batch:( but nothing stellar anyway. even the not so good xeons make ya wonder why people mess with the 8400 and 8500's. zerotherm nirvana nv120 cpu cooler, no agua here
Pff my Q802 is BAD. 1.3V to go to 3.6, and 4GHz is just a voltage-hell. I have noo screens, no net on the Xeon.
