FPO Q740A553T 12/20/07
VID 1.1125

if you are prime/orthos stable you`re great M8..
As someone posted in another thread, Intel designed these core sensors to read extremley high core temps to throttle down the cpu when overheated. They apparantly were not designed to be used as thermometers or necessarily be accurate at lower temperatures. While some enterprising software designers have brought out programs to read these core sensors, Intel is probably not obligated to ensure their accuracy at low temps. Intel's own Thermal Analysis Tool does not work with the Wolfdale cpus.Quote:
I do think, as mentioned, that those core T are false.
My e6320 in the same system, idle core T were @ 20sss (1.4v)
Q743A748 @ 4Ghz with 1.288v 30mins OCCT Stable.

mobo: DFI Blood Iron
memory: Crucial Ballistix DDR2-667 2x1GB
gpu: eVga 8800GT 512MB
cooling: water
psu: Corsair HX620
hd: WD250
vid: 0.8750
This is somewhat of an adventure. I had the latest BIOS from DFI but it would not allow me to disable EIST and the other CPU protection options. I would set vcore, multi, and FSB in bios but only the FSB would hold. When I launched CPUz it would tell me 6x multi and 456FSB. So I flashed to a beta bios found on T-Mod's DFI CD (give that guy a cigar). Now I can run the E8400 without any issues other than the temp discrepency.
My WC system needs a kick in the ass and my memory timings need some work but I will address those next.
Anyhow, here are 2 quick SS. This SMOKES the E6750 it replaced.
sofarfrome nice vid.Whats the batch?
Is this the lowest we've seen so far?Quote:

I figured I would ask you fine people if anybody knows what the average Intel specifications for the E8400 Thermals are under idle and load and the core temp (if its different)?
I've been looking around but all I can find is people talking about their temps, not the actual recommended guidelines.

you got the exact same vid and batch as i do, may i know your waffer #?Quote:

What do you think is the best, cheapest P35 board for these?
I want to order a E8400 off the egg tomarrow, but i don't want to spend the $200 on a X38 that i had planned.. :(
Would rather have a stacker + P35 :up:
Im wonder which mobo is best, im thinking the blood iron is awesome
Go for the P35 + stacker because X38 is not much improvement from P35.Quote:

These should OC well with 4 sticks of ram and good FSB?
I hate to ask all the questions, but i might be ordering in the morning :up:
Look at the description, it said 45nm ready, but sometimes you do need to flash the bios.Quote:

Edit: E8400 @ 4.32ghz with 1.4v
http://i31.photobucket.com/albums/c3...l_w/432ghz.jpg
Oh man all these great results and I'm stuck with my Q740A523 taht I can't for the life of me get stable on my P5N-E SLI board.
I know there isn't an official bios yet, but there are some guys on here that have gotten it stable, so I'm willing to give it another go.
One note. I noticed when my system crashes from not being stable with the E8400 instead of your typical black screen of nothing, or just frozen screen, or bluescreen of death, mine is black with yellow text.
The yellow text being to blurred out to read. So it's like a BSOD, but black with yellow text that can't be read.
Anyone else?
I will give this another try tomorrow or something.
Wish a bios would come out for my P5N-E SLI
1.45v is about the max voltage for 24/7 use right?
I have a 746A328 here, going to try it this weekend :up:
Let's see what my P5K and this chip can do...
Dunno know but I will check when I swap my WC block this weekend and let you know.Quote:

It is a sick board, but like so many DFI products it is allot of work at the begining. I Personally love the board as much, if not more than my Ultra-D, but am having issues with GTL Ref adjustment past 4.3Ghz. I am sure I will get it ironed out.Quote:

cool:up: . ive read quite a bit on the dfi p35 thread and it seems like a very solid board. im hoping for a 3.6 to 4.0ghz 24/7 with this chip. im kinda new to overclocking but would like to get more into it. thx again.
anything conclusive on what sort of voltage these chips can handle for 24/7 (similar to ~1.6v being about the maximum acceptable voltage for 65nm chips)
I'm saying 1.40v AIR -1.5v WATER.
Anyone popped an IHS on these yet?
You will also be quite pleased with performance per clock compared to your 680i. I had my Quad @ 4Ghz on my 680i and I went to the DFI and beat my 3DMark06 Score by 700 points at 3.85Ghz :rolleyes:Quote:

So far 4.0ghz orthos/occt stable @ 1.33v on a P5K... have no idea what all the BIOS voltage options do but I'm learning lol... 4.1ghz will boot but won't pass orthos for longer than 40 seconds :DQuote:

I throwed some Orthos at it @ 1.55v @ ~4500Mhz. Cores jumped straight to 75C and they we're surely gonna get hotter then that, maybe 80C :D
now the final result..
E8200 @ 4Ghz with 1.216v :up:
http://www.muenster.de/~e30pics/Bild...z-Prime_kl.png
nice with so few Volts for an E8200 :)
I just started to play with this Q748A142 E8400, i think my temp are high, i did try remount but still i idle @ 42c same temp when i tryed to oc some coretemp is wrong i think maybe because om 780 chipset or something... well first try
http://img172.imageshack.us/img172/8...thosaj3.th.jpg
i think my temps i high but cant get good temp:/ im running WC.
So you actually have two premium boards to play with? Damn. I'm wondering if should sell my unused IP35-E for the DFI board. I just haven't seen too many IP35-E results, especially with low vcore. But maybe that's cpu-based, not mobo-based.Quote:

Very nice. Same as my 8400 Vcore under load at that speed. Rare chip.:up:Quote:

Ok, I'm screwed. What BIOS are you using?Quote:

I used the 14 Bios temp didn't seem to move at all and Beta 16.04 bios worked but as mentioned stayed at 42C til I moved past that tempature I think.

Haha guys thats nothing,
Mine is at 58 always, but does not get hot at all, under load it gets 60-65celcius, I think its buggy reading in the chip, does not bother me.

What were your load temps (using what sw?) with a orthos load or something?
CoreTemp is the only program guaranteed to be reading the value of the on die digital thermal sensors (DTS) within the Intel core CPUs. Any change in the version of the bios you are using will not change what CoreTemp reports.
You can use CrystalCPUID to read Model Specific Register (MSR) 0x19C directly. The data contained in bits [22..16] of this register is a 7 bit number which shows you how far you are away from TjMax. CrystalCPUID also lets you select which core you are reading the DTS data from. This same data can also be displayed using CoreTemp when you go into the settings and select "Show Delta to Tjunction max temp."
CoreTemp then takes that data and plugs it into this simple formula:
Absolute Temperature = TjMax - DTS
For the E8x00 series it is assuming 105C for TjMax.
Check out post #210 to learn how to test temperature monitoring software.
In previous testing of the dual core Conroe processors I found CoreTemp to report absolute temperatures very accurately from about 45C to their TjMax of 85C. In my opinion the DTS sensors are not accurate at low idle temperatures and will typically report too low. Intel designed and calibrated the DTS sensor to trigger throttling at TjMax=0 and CPU shut down about 20C after that but has never publicly documented its use for reporting idle temperatures.
Another user reported having a cpu where the DTS on one of his cores was stuck at a fixed value. It could go higher under full load but not any lower. It would be highly unlikely that both cores were stuck at the exact same fixed lower value. If anyone sees that then try turning down the core voltage and MHz to default or lower and see if you can force the temps lower. If it still doesn't go lower at idle then you should return it. If it overclocks like a MOFU then I'd keep it! :DQuote:

What are your other voltage settings and what are your load temps?
As long as you're confident that temperatures are in check, out of the way readings are probably just that. A lot of these chips are reporting erroneous values for temperatures.
Anyone wanting to return their CPU because of temperature readings need to do it through the place of purchase. Intel does not recognize 3rd party software as a valid temperature reporting method for RMA.
What were some of your load temps?Quote:

Thats no benching for me this weekend... arse!
hiya devious i thought i'd get mine today from advancetec as well so its going to be monday then , we hate waiting
It could be your ram? maybe update bios? try to play with it first then attempt to hit home run later?Quote:

Just remember that number is not measured at the same spot as what CoreTemp is reporting. The Intel number is measured at the geometric center of the IHS so CoreTemp numbers can go higher since they are measuring at the hottest points on the two cores.Quote:
