dude when i posted the 4.5 i thought i was stable..
then i tried to reduce the NB voltage.. and it failed
and the weir part when i leave it at auto it works which is far less than what i was pumping in.

thats y i suspect the nb/pll was faulty..
eventhough the 500 fsb pass a 4x8 for memtest..

thats y i reran it...
and it failed..
so until i do watercooling i cannot guarantee the bus..

3dmark cpu test 5 times run.

[attachmentid=389052]

i will run for u.. orthos blend or small fft.. later at night since u asked...
u can already see my Northbridge temps are freaking hot..
for 500fsb i need 1.8v or pll and northbridge.

how about i post some crysis benchies.. say increase it to 10 runs..

i am just posting all this since i was accused as a faker for the 4.4ghz
so just defending myself..

but for ure problem for games..
if u say it passes 3dmark sp32m.. and fail it games.. usually its not proc.. its ure NB/mem.
since games dont stress the cores much.
and did u know that CPU stress test on 3dmark on loop is equivalent to ORTHOS priority 8 basing on temps.

let me make it clear.. which i will post to ure hearts content later at night..
4.5ghz passed this
3dmark06
3dmark05
aquamark
sp1m
sp32m
OCCT 30 minutes
Prime 95 small fft 15 minutes

but failed memtest windows running two instantaneously 800mb each  in 30 percent only and this was after i posted the remarks and benchies..

nice result...4.1Ghz@1.35v....try to push it more drool.gif

Will do so, now assraep-ing the proc with folding to check stability..

The reading is wrong, its not hot at all fyi.

Btw i did notice about the small fft test at orthos. It should be Min fft - 8k and Max fft 64k, not 8k for both. smile.gif

The setting might go berserk after a while, weird but i noticed the changes of the values while orthos.

Guys WTA i'm currently overclocking my E6300 to 2.67 GHZ....Any Higher ORTHOS/Prime will Hang in 1 hour

Issit my Ram problem ? Because I'm using 2x Corsair 667 Value RAM DDR 2 at 381x7 FSB

Can I OC more if I increase the RAM voltage by 0.2v will This Burn my RAM ? (have the Dominater Cooler on my RAM w/o Heatsink)

What is the default voltage of this Value RAM ?

using A Gigabyte GA-965P-DS3.

Lower your multi to X6 and try again to see if its the ram limiting you. smile.gif

nice clocks at 4.2Ghz, maybe i should try the wolfsdale too. I wonder why wolfsdale is in penryn thread. Is wolfsdale under the penryn family?

Wolfdale and Yorkfield is under Penryn family. smile.gif

Yup, Penryn is the 45nm family. Wolfdale and Yorkfield is not the Penryn's children but Penryn is more like a codename for the 45nm procs. biggrin.gif

Owh, meaning..

vcore - 1.264v
vmch - 1.57v

vmch is quite high and low vcore.. hmm.gif

i wonder the nb can take that much vcore for 24/7 setup... hmm.gif

ya, that's what i was thinking about. too much volts pumped to the nb.. sweat.gif


Btw guys, how much is the max vcore for the 45nm proc can take ?

i need +0.2v on the mch to get it stable at 4.2ghz.

i will try lower vmch and vcore on the e8400 coz i think 1.4v and above is too much for it. hmm.gif

ive slapped a evercool vc-re hsf there. about the high vmch, a few of the wolfdale user need high vmch to get it running higher and i wonder why also.

Bro, one thing i notice is that the small fft setting go hoo haa coz u can only see it at 8k max.

Try custom, Min 8k Max 64k and time to run each fft 1min. That way giving more stress to the proc and faster for 1 round. If Min 8k and Max 8k easy to pass.

okay will do it but do u know the reason y they made the fft run around 8-10 minutes.. because of the priority cycle..
u need to off all the programs..
its like shooting a gattling gun every 8 mins..
what ure asking is not stress dude.. what ure doing is every 1 min off and on the load and restart...

small fft is to just to test ure L1/L2 cache interaction with ure core.. hence y prime states run 8k min to max 4096 on 15 mins interval..
so wolfdale would be 8k to 6132 max.
what ure saying is every 1 min example on real life  on and off a program that stresses ure core... not real world test..
my 2cents.
here is 1 hour pass.

memory stable as hell.. proc also..
perfect.

What i meant for the 1 min per cycle is to make it faster per cycle bro. Read again. It gets the error faster so you no need to wait for quite something.

About stressing it more is the 64k, sorry for the typo.

Yes i get what u mean. This is what i do, find the error first. If no error proceed with longer time eg. 15 minutes. smile.gif

Yeah, its a good test imho. A plus to check the system's stability. For those who have load line it doesnt harm to test it i suppose. lol

The 64k mx fft was the original settings of the orthos for the small fft test, not my method. Just that the settings gone berserk after a while if u stress it then stop for quite some time.

The only thing that i tested was the 1 min per round, since it could detect the error faster saving more time to test it.

Actually it was the default settings for the orthos small fft bro. I know about the 32k for max fft bcoz of the L2 cache. But i am wondering why it is there for default settings ? hmm.gif
