Does anyone know where to put red line of multimeter on my motherboard to measure vCore? I've got EVGA 750i FTW. Asked on EVGA forum but nobody answered me...

It will be awhile before we see E8400 and E8500's with E0 steppings. Probably 1-2 months I'd say before you can get one gurrentied. Best bet would be going to someone that lets you pre-order said CPU's with the stepping.
It cools my CPU and GPU. The NB on the p5q doesn't really get very hot as it uses a smaller 65nm process.Quote:

One great Wolfie you got there! :up: Gratz. ;)
^^^^ nice. 4ghz for me is 1.256 so im close lol.. i can pass orthos at 4.3 now with 1.348 temps are about 75c though. my vendetta 2 came in today damaged (they sent me open box crap i called and screamed and a new one is coming all the fins were bent parts missing ripped box etc sucks) so hopefully when i get that ill be better or i know i said i wouldnt but maybe water will be next lol i still have most of my stuff from my 478 setup so i would just need new blocks.. rad, pump and res, are still fine

SmallFTT loads the cpu, while Blend loads the ram and cpu, I believe. So if you're failing Blend, you should try upping the vDimm, especially if you are running 4-4-4 timings overclocked. I use 2.0v @ 1190 MHz with my Ballistix, but with 5-5-5 timings.Quote:

But why did my computer pass prime Blend before with all the same motherboard settings, except with lower vCore (smaller CPU speed)?Quote:

Not only vdimm, Blend do have to do with Memory and MCH, so upping the vMCH is also an option not only vdimm. Try upping MCH first, then vdimm. One notch in vMCH can do the trick sometimes :)Quote:

Tried this morning LagunaX pencil mod.:D Shame I still can't find the right settings for 4000 but I'm happy with this OC for the moment. :) Before pencil mod my cpu could do 3600 at 1.25(bios)-1.2(cpu-z). Now 1.75(bios)-1.6(cpu-z), still some drop. Should I put more graphit? And it is mandatory to put nail "thingy" or it will do the job without it?

RealTemp 2.70 is available for download. It looks like Ovidiu's post above.
It's more efficient than the last version and has a few more features like proper core reporting based on APIC ID for the Quad processors, the reporting of both Minimum and Maximum VID as well as a high temperature alarm feature and the ability to save the log file in .csv format so it can be directly imported into Excel for analysis.
Here's a 9 hour run of RealTemp and it's competition with both minimized to the SystemTray. The CPU Usage Time speaks for itself.

If you double left click on RealTemp you'll get a nice small window with just the basics. Perfect addition to a screen shot.

Back on topic. Here's the Intel sSpec numbers you should be looking for if you are trying to get a new E0 stepping CPU. This number is on the outside of the box if you have your hands on one or can find a retailer willing to have a look.
Revision C0
E8400 - SLAPL
E8500 - SLAPK
Revision E0
E8400 - SLB9J
E8500 - SLB9K
thanks for that info, very useful.
10x for the link to RealTemp, nice one, it is a lot better than the prevision one...:D
The start minimized now works in vista when putting a link in the startup folder :)Quote:

4.1+ with 1.31v (this can run all day long like this with 0 issues) i think i can go to 4.2 on the same voltage (benching now at 4.2 with the same voltage so far 28 min orthos stable!!!) though with the vendetta 2 made a really good difference over the 1283 almost 7c overall!!!:
my second e8500 is pretty good, this failed after a while, trying 500x8.5 now.

It's still luck of the draw though. There isn't enough evidence yet to say for sure but generally when Intel updates a processor, the overclocking abilities increase as well. There are some nice Revisoin C0 chips in this thread that are better than X-Bit's E0 at the same voltage.
my e3110 at 4.1 with 1.3375 bios would load out about 10c higher easily.Quote:

Im buying E8400 and I found one quite cheap. Only problem is that VID is 1.225V (that looks quite high for me)
Batch is Q748A and it looks like quite different OC (from 4.2 with 1.3V to 4ghz with 1.4V) Owner told me that he overclocked it on 3.4Ghz with 1.225V (he isnt a very good overclocker) What should I do? Should I risk it?

Ok, I have a few thoughts/questions. I have a Q6600 (GO), a Q9450 (CO) and an E8500 (CO) that I have been benchmarking against each other. My q6600 was my first quad, however I was able to get a Q9450 for $170 after the live.com rebate. The Q6600 is capable of running 3.725Ghz (416x9) 24/7 with no issues. The Q9450 has been able to hit 3.7Ghz (8x463) @1.44v, again, no stability issues. I got the E8500 because I knew I could overclock it even higher, in fact I had no problem doing 500x9, although the voltage was at 1.51v for stability, hadn't tweaked it yet, so I am sure I could come off of that. Temps on all three are no issue since I have watercooling, in fact under load the highest I hit was 63c (ambient is 27c) on one of the quad cores. Anyway, I am suprised by some of the results from benchmarks that I ran, keep in mind this was some limited testing, but still suprised me. I ran PI, 3DMark06, Vantage and did a conversion of a 4gb HD MPEG2 video to DIVX using Divx6.8 converter. I was expecting that the E8500 would blow the quads out of the water due to being able to hit almost a 1Ghz faster speed, but it didn't. Sure PI was faster, but for instance on 3DMark06 the Q9450 had a better score at 3.6Ghz than the E8500 at 4.5Ghz, only a couple of points mind you, but still. The biggest difference when you break down the score was the cpu score was much higher on the quad, same thing on Vantage, although the overall score wasn't even close. On PI the E8500 killed the two quads easily, but in the Divx conversion it wasn't until I hit 4500 on the E8500 before it overtook the Q9450. I know Divx 6.8 takes advantage of the multiple cores and the new instruction set, but I would have thought the higher FSB/CPU speed would have been able to take the Q9450 out. So I guess I have two questions for everyone here:
1 - Why wouldn't you get a Q6600 for the same price as the E8500 instead of an E8500? Yes, I do realize that the newer Q6600 don't overclock like the older ones, but just from reading in this thread I haven't seen too many folks willing to push their chips further than 4Ghz, so a Q6600 at 3.2Ghz (the new Par for them) should be just as good as the E8500 and it future proofs you.
2 - Is there a reason why many people are not pushing their chips pass the 4Ghz limit? I get the "keeping the voltage low" idea, but isn't the reason that everyone wants the E8400/E8500 is for the overclocking capabilities?
Maybe I am missing something as I had high hopes for the E8500, especially since I could probably run it on far less voltage than my Q6600 and have lower temps, but I am just not seeing it. My point is not to bash the E8500, so don't take it that way, I am just trying to find a reason to go to the E8500 from the quads and I can't find it.
Convince me, please. :)

I got the same Q746A535 batch as you, gurusan, but my VID is listed as 1.125v in CoreTemp, the same as my previous E8400 (I returned as it had stuck temp diodes).Quote:
Thanks. THe batch is Q746A535 . 1.225 VID. Not amazing but certainly not bad either!
I was surprised yours was at 1.225 VID coming from the same batch as mine? But RealTemp shows my VID as 1.225?? At stock my voltage reads as 1.128v in CPU-Z...but I forgot I had C1E enabled! When I disabled C1E at stock settings, sure enough my voltage was at 1.20v, which is more like 1.225v with VDrop. My Xeon 3110 clocks to the exact same 4620MHz maximum as my previous E8400 did with 1.125 VID, (with 1.60v cpu and 1.2v VTT in bios.)
You must be using the older version of Coretemp to view your VID. The latest version 0.99.1 detects it correctly.Quote:

W/C system is in my Sig. As far as cost, I stopped counting a long time ago, but if you look at retail on the items, then I guess....OMG.... :shocked: I have an addiction, crap. Well, a lot.
Anyway, I will probably try out a few games instead of just 3Dmark06 and Vantage. I like the idea of saying "My system runs at 4.7Ghz, nah nah!" :D but seriously, I am having a hard time justifing it. Anyway, thoughts and opinions welcomed.

Mine needs 1.376V under load to run stable at 4,0 GHz. Maximum temperatures under load while stress testing are 64 C. Is this OK for 24/7, or I should run it at lower voltage?
to hot ? thats a hard question the limit eye believe is 72c
but 50c to hot for me
1.376 and 64c does not sound at all bad for benching or stress testing. While those numbers would be a bit much 24/7 keep in mind that you will rarely attain those temps during normal usage and then not for long. The consensus on vCore seems to be to not exceed 1.4v.
So, I'm fine with 4,0 GHz. Anyway I have strange proccessor batch. For 3,6 GHz it needs 1.232V under load, for 3,8 GHz it needs 1,304V under load, and for 4,0 GHz needs 1,376V under load... it has big gaps for little change in speeds...Quote:

The more heat it absorbs and the less heat it dumps out to your radiator. Your 71C core temperature makes a little more sense now. :yepp:Quote:
