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

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:

This will allow CPU-Z to report the correct VID where it normally reports the core voltage. I think CoreTemp fixed this in version 0.99.
dose this chips degrade once only ? or they keep degrade for ever ? :p i could ran @ 4.2 with 1.35Volt and now only with 1.41 :(
if the cpu has degraded then what voltage can we give to them for 24/7 ?
lets say we need it 1.41 for 4200 can i feed him with 1.5V now for more Mhz ? how safe is this ?
ok just got 2 more E8400's so to whoever is keeping track which is doing better
batch# q814 or q817 ?
thanks;)
newer batch seems better most of the times :) try the q817 first
great ! thanks for thr fast reply !
will try in an hour or so (still folding ...at 93% now )

well i'd figured my first post (IIRC) on this forum should be about my latest endeavor in overclocking
been dabbling around since AMD 939 Days - MSI Neo4 Plat FTW :up:
but i've been using a Asus P5N-e SLI board for a while now (yes I know bloody old) but she's treated me well and allowed me memory options not avail to you Intel chipset users
*actually on my 2nd of these boards)
I got the pencil vdroop mod finished up on her and have just started using a TRUE (Ninja before that)
here is my basic system
E8500 - testing
TRUE120
ASUS P5N-E SLI
2x2 Mushkin Redline DDR2-1000 - TESTING
Zalman 600w
Audigy 2ZS PLAT
XP PRO SP2
Highest I've been hitting stable on my E8500 is 4037mhz (thats kinda a lie as 4275mhz had been semi stable for 1-3 hours OCCT on 1.33v but it would vary how long it'd be stable for - never 6+ hours though - never long term stable regardless of cpu voltage or NB voltage)
here is a screen shot (1900x1200) and cluttered desktop
http://johndoe.hotlightbulb.com/7%20...e%20orthos.JPG
seriously thinking about going to a new board as i think my cpu has alot more in it and i think i need to do a remounting on the TRUE as I think temps are kinda on the high side (but I could be wrong on that...)
looking for advice & opinions on getting a bit further :confused:http://johndoe.hotlightbulb.com/7%20...e%20orthos.JPG
I used v0.99 and it is still below 1v (0.9750).Quote:

and ya my sys shows 1.22 for vid on both :down: hope your right and thats wrong
havent had time for screenies yet will put up after finnished

CoreTemp 0.99 shows 1.1625 volts for max and 0.9500 volts for the minimum.
If VID can change depending on what motherboard you're using and how it's set up then is there any point in comparing VID?
VID might only have some meaning if you plug two different E8400 chips into the exact same motherboard and use the same software and version to compare with.
I'm a bit of a newbie to overclocking. At the moment I have a E8400 batch Q810A237 which I purchased from Newegg about a month ago. I'm only able to overclock it to 3.40ghz anything beyond that occt produces errors in a matter of minutes. Is it my ram that's holding me back? I'd appreciate any advice on how I could at least overclock it to 3.6ghz or more with it passing occt. Below are pics of my current cpu-z. Thanks in advance. :)
No, its your vcore.Quote:

In my way of benching, Prime95 Small FFT's for, at least 12+ hours, and then Blend test, for another 12+ hours, show you stability!:cool:
Just for the record!:welcome:
That was just because you said heavy load :)
Of course that 5-6 hours are not enough to see is your system really stable. We understod each other I hope ;)

after wasting all night on that E8400 batch #817 !! it sucks wouldnt go past 3.8 stable at 1.365 volts !!
MY new gem is E8400 batch #814 took less than 15 min to get stable at 4.0 would work at 1.22 volts for 100% stable used 1.285 volts
didnt have time to play with it ... (in a compition for a Q6600 had to get back to folding each w/u is a ticket in the drawing)
but with further tweeking hope to get it down to 1.25 or so:)
told you so you were in for a treat HDCHOPPER :up: mess with them GTL volts and get that baby rockstable mate !!! at loooooooooow volts... I can get mine stable now at 1.27volts with 8 x 500

janjan: A lot of temp monitoring software is using the wrong TjMax. Download RealTemp and see what it says. Here's some software temp testing of an E8400.
Run CPU-Z and make sure your core voltage isn't too high. Some Asus motherboards when the core voltage is set to AUTO get way too generous with additional voltage when you start to overclock which only creates extra heat. Most E8400 chips can run 3.6 GHz with about 1.20 volts and many of the better chips can do it with less than that.
Absolutely true. When i installed my e3110 yesterday both coretemp and everest were returning a wrong temp for the cores. RealTemp was instead getting too low. Setting a tjmax at 95c is giving believable results.Quote:

Curious how many of you guys went from a Q6600 to one of these? Any complaints?
I do. Complains... not really, on multi thread apllications only and for sure, I may say. The rest is at the advantage of the E8x00. My opinion of not so noob but not very experimented clockerQuote:

FYI damaged one core at 4500 MHz at 1.6250 when one core went to 102c, realtemp. Still runs ok but will not complete a stability test.
you'll be so glad moving from 650i man ;) wolfies do not OC so good on those nforce chipset because of the "little war" between Nvidia and Intel.Quote:
