From what ive heard Prime95 isnt really good for the 45nm chips well even the 65nm, Will not see me using it for stablity testing
Heard is damages the chip in some sense. From what ive heard tho.
10°C is the difference between TJcase max 105°C for coretemp (can be altered) and 95°C for Realtemp... for more info on the matter search for the Realtemp and coretemp thread.... I have no clue which one is correct so I alter coretemp at 100°C Tjcasemax to be somewhere in the middle....
I think OCCT loads the CPU more but it's test is more limited run in time : 1 or 2 hours unless you select infinite...I don't like peeps doing 24hours plus prime... as it continues it's stress test even when one or more cores (quad) fail... OCCT aborts in that case... I run prime for an hour or 2max (small FFT's for CPU test) cool down... OCCT blend test and then it's off to folding@home... if that passes overnite I'm pretty happy... 3D stability is another thing
Use Real Temp for 45nm CPU's and do the calibration test when it is idle to get better (real) temps.
RT is showing correct Tj.Max (95°) so you can set it in CT at 95° and you'll get the same temps as Real Temp showing you.

Q813A199
Found I had to keep vcore above 1.3v under load to hit 4.0 stable. My board has some bad vdrop/droop, so I think it was around 1.365 in bios to hit 1.344 idle and 1.312 load. Will try to push it higher sometime, but I can't stand listening to the fan on my OCZ vendetta on high. It does a good job on low setting for a 92mm hsf, but it is way too loud on high. I'll be getting a quieter fan soon enough, and I will see how far I can push it on air.
edit- signature didn't show so here is my specs:
E8400@4.0
Mushkin 2x2gb PC2-6400@890 5-5-5-15 2.1v 1:1
Gigabyte ep35 DS3l
EVGA 8800GT 730/1825/1952
OCZ Vendetta 92mm hsf
Corsair TX650w
CM 590
Samsung 220WM, 22" widescreen
Vista HP64
I am in the process of reviewing the vendetta 1 and 2 for OCZQuote:

Vendetta 1= 4.22 gigs
Vendetta 2 -4.34 gigs
Agreed Vendetta 1 gives you headaches after a while===OUUUUUUUCH
oh and...............

This is in DFI's budget x48 Dk board
Bit dissapointed on the amount of cpu volts used, but shrugs on a 4 phase=hmmmmmm

My temps never read below 36c as far as I can see. While at 3.6Ghz and 1.52v full load the temps are in the mid 40's, and it was rock solid stable for a month and a half.Quote:

Also, I have a 120mm fan on the Ultima 90 and it is locked at 1500 RPM, so the air cooling is helping those temps somewhat as well I think.
Which Batch sir Gilgamesh ?Quote:

There are variables, such as PSU and MB, but ultimately, the batch (production) determines how good the CPU is.
Normally it's the reverse... a higher multi with a lower FSB to achieve the same final speed should be obtained with less Vcore...Quote:

Agreed, it would be sweet to have an unlocked E8400/E8500. Did I hear (read) correctly, there is an E8600 10x coming out? If so, that will be a train I want to board.
Yep E8600 is on the way, there's an ES test already in the Intel section together with a Biostar mobo... will be easier on some to get eg 10 x 400 stable on some mobo/ram combos....
Well I was doing some testing trying to find a good daily clock which revealed some weird results on my end.
9 x 433 (1733fsb) using 1.296 load = orthos fail at 3min 51sec
8.5 x 459 (1837fsb) using 1.296load = orthos stable for 2hrs 30min ( I stopped)
Could well be ram limitation here, which mobo ram combo ?Quote:

Help decide what E8400 choose:
Q813A518
or
Q807A463
What box to open?
Q807 same one I have in use too, its ok ~1,33v 4,0Ghz but im interesting how good is Q813?
I would go for the Q807 but if you are curious for Q813
Q813A199 4Ghz 1.32 Vcore Jacke231 Gigabyte EP35DS3L
Q813A499 4Ghz 1.28 Vcore The[R]eaper DFI Lanparty LT X38 T2R
does anybody have infos about Q816 ?

Look at my list Toyten and continue the search !!

thank you leeghoofd, but as I'm very happy with my Q807A367 http://pix.nofrag.com/7/0/d/cab98df7...4820b449tt.jpg , stable Occt priority normal on cpu 1h for 1.38vcore(CPU-Z & Occt readings 1.4 vcore bios) for 525x8, with a 1.2 VID(CPU-Z v1.45 reads 1.176v) I stopped the search on that CPU.Quote:

I'm thinking more like a nice easy 10x450 :DQuote:
