Testing / comparing : Intel D975XBX2 / Asus P5B DX ***56K WARNING***

[argylesocks]

C1E should be OFF - (not sure what it does)

EIST- OFF ( this is speedstep)

ALSO- WATCHDOG has to be off. It screws up overclocking (you get to the watchdog function but changing the bios jumper to get in. Change the watchdog and shut down after the save. Replace the jumper to normal positionn)


Hope this helps, Stan

so, C1E changes the multiplier... does the voltage stay the same?
what does EIST do?

edit: actually, is there a linky that has more info on the bios? it would be nice to see everything with an explanation of what it all does.


edit#2

EIST. that stands for Enhanced Intel SpeedStep Technology.
EIST is a feature, that adjusts your Multiplier, depending on the level of activity of the CPU.
if all your CPU is doing is browsing the internet or typing, then it will default to the lowest available multiplier, since its basically doing nothing.

this is to do many things, save on CPU power, save on actual power used, and to save on heat put out by the CPU.
theres no reason to have a CPU at full speed... if your only doing little mundane things like listening to a MP3, or browsing the net...

theres also... C1E.

C1E is a feature, then when it first came out, drove me absolutly nuts, cause no where was it explained what the feature was or even what CPU had it, for awhile after it started being used in processors.
so I'd be overclocking, run super PI, and get some great run... then C1E would kick in, and my voltage would drop from 1.5 volts, to 1.2 and my OC would stay the same... and this would always lead to instant CPU freezes.
this one single feature drove me so nuts trying to figure out what was going on, when about a year ago it started being used, and my Abit AS8 had no option to disable it, and I had no idea what it was...
I got to the point where I almost took the board outside, and smashed it from being screaming mad.
had I done that, I would have killed a perfectly fine board... cause this is a CPU feature.
a realllyyyyyyyyyy annoying CPU feature.

what C1E does, is lower the Voltage of the Processor, when at Idle, to save on heat output.
remember, a CPU is meant to only be run at stock.
Intel designs these CPU's to be stable at thier stock speed, with C1E active.

however, C1E for a overclocker, can leave you going nuts if you dot know what it is.
especially if you have a older LGA processor, that doesnt have EIST on it, but does have C1E.

C1E. if used with EIST, is actually a handy feature to have, if you want to keep your CPU temps low while at idle.
but if you choose to disable EIST, I strongly suggest you disable C1E at the same time, otherwise, this feature may drive you bonkers too, just like it did with me.

after searching this thread, i then check the stick guide (duh, should have check this first)...

so what is changing the multipliers? the C1E or the EIST? does the voltage ever get dropped with the new bios 'bug'?? if so, is it causing stability problems? or does it work hand-in-hand & drop the multiplier down at the same time?

with it enabled, how quick is it to know when the cpu is under load? is there any lag while playing games, etc??

thanks
