LynX measures the CPU performance in Gflops. (It's something i havent heard of apart from the more familiar Lucas-Lehmer test.)
This pretty popular among russian overclockers.
LynX stressed the cpu way more than Orthos and Prime95.
It is claimed that LnyX saves more time bcoz 1 hour of LynX stressed test is equivalent to 6 hours of stressed test performed by prime95.
Bcoz of this, it is known that LynX raised up more higher temps than u get when running 'Large FTT's' on prime95. e.g 10c-15c more!
So u have to be careful when leaving u'r PC unattended when running this software.
(Large FTT's on prime95 already makes my cpu really hot, i will expect this software to raise my cpu temps up to 80c, even with my Artic Cooling Freezer Xtreme.) 

Here's a thread on Lynx from the original creator:

I'm gonna try this 'linpack interface' soon...

wow.. is it? not aware of tat.. I din use prime95 cz i noe its time consuming and straight using LinX..

I stress my E7400 @3.2Ghz for about half an hour and hit the max temperature of 58°C at night..

Maybe those people who got their temps very high because:
1. using stock cooler.
2: OC more than 3.6ghz on C2D
3. OC'ing Quad proc up to 3.4ghz+
4. Set their Vcore more than 1.45v+ (Increase in temp relevantly due to increase in voltage/vcore.)

Your e7400@3.2ghz doesn't get really hot bcoz you still can use stock vcore @ 3.2ghz. My E7400 does.
It's when u OC up to 3.6ghz+ is where u'r in business.  
I used set my vcore on 'AUTO' when i was still OC'ing @ 3.5ghz (334 x 10.5) a month ago.
(now maintain around 1.3625v @ 3.6ghz~3.8ghz, can topup to 4.0ghz+ if i want, but somehow i luv my proc too much to push it that high)

Have you encounter any bugs/problem in LynX? Unless u have the latest version: LinX 0.6.2.1
(I will download LinX soon to try it out later)

Nywayz, there's a thread on LYN about LinX:

i got 90C..

90c    
Buying a proc at the shop really like playing blackjack or lottery,
its all starts when the salesperson picks up your proc randomly among other processors on the shelf.
It seems in this game of "processor lottery", u looked unlucky bro...
Statistically-wise, some say the probability to get the 'unlucky' chip from Intel is less than 2/10.
I read some people(usually highly superstitious geeks) up north in mainland China will choose a proc by their serial number,
apparently they want the s/n which has a lot of '8's in it to avoid getting the 'unlucky' chip. You tell me...

mine also using linx 0.6.2 today to stress my E7200 @4.0ghz 1.32v

hahaha..the result temp so high for both core...reach 92'C then auto shutdown...using thor's hammer cooler...

yup.. i OC to 3.2Ghz and stop there last time bcz i was still using stock cooler.. and yes @ stock Vcore..

now i'm planning to push it to 3.6Ghz when i'm free.. not going for 4.0Ghz anyway..

can share yr settings for 3.6Ghz?

i just downloaded 0.6.2 today and will giv it a try later tonite..
I'm using 0.5.9 before this and never encounter any bugs so far.. (or i din notice it  )

wow.. tat's insane.. what's the temperature before using LinX? how long u stress yr proc?

stress about 5 minute..then auto shutdown...before stress idle 40'C

normally i'm using Prime95 to stress my proc...maximum 75'C

The Thor's Hammer is Xiggy's finest cooler, and u got auto shutdown from reaching TJ max?!!
Man I start to think LinX is somewhat of a monster..

Probably Linx is equivalent to Crysis in comparison to gaming...in the form of cpu stress test
maybe i gotta plan for watercooling for this test 

maybe my mobo bios setting...i enabled auto shutdown when cpu reach 90'C in bios..by default it's set 85'C

actually i wanna to try 2nd hand CoolIT Domino ALC...but no luck because the seller lost backplate for 775 socket...

Yes, @ 3.6ghz:
400 x 9 fsb; 1.336v~1.344v
IDLE : core0 = 31c            core1 = 34c
LOAD: core0 = about 60c  core1 =  about 58c   
No OC on Dram bcoz the increase is minor in terms of performance.
(but sometimes I increase my 800mhz by 20mhz and 400fsb by 10 to keep that 1:1 ratio, e.g 410 x 8.5 fsb @820mhz DDR2 =3.485ghz,
fairly stable depends on the mobo and cpu) 

Make sure u disable most of these settings when OC'ing the cpu:
Intel® Virtualization tech, CPU TM function, C1E, and more importantly disable Intel SpeedStep ™ tech

And of course I got aftermarket cooler: AC Freezer Xtreme

I recommend that 1.336v~1.344 is enough for 3.6ghz on a E7400 chip. If not, then just increase OR decrease in increments.
(Make sure it's 1.336v-1344v in CPU-Z, in BIOS u might need to set the vcore slightly above 1.336v)
Remember this is only my opinion based on my e7400. I hope your E7400 is not that different. 

Addtional info:
@3.8ghz
400 x 9.5 fsb; 1.352v~1.3625v

@4ghz
400x10 fsb; 1.3600v ~ 1.3625v (i try not to go above 1.3625v since its not recommended by Intel when OC on 45nm chips)
Even at 1.3625v@4.0ghz its seems quite stable

ModernoPC got stock if im corect

btw how about Corsair H50 ?

Make sure u disable most of these settings when OC'ing the cpu:
Intel® Virtualization tech, CPU TM function, C1E, and more importantly disable Intel SpeedStep ™ tech

Don't ever2 disable CPU TM function... unless you want to fry your procs...
