#2 E8500 Q748A212 + Commando under 8" but...

Today i tried my new E8500, the second Q748A212 and another Commando
The OS wasn't the best, an xp pro sp2 OS mid tweaked, i'll try again with ma 2003 server OS.
Anyway i'm happy about this chip, atm i'm vcore limited on Commando, anyone know an OVP mod? I need more than 1.92v :p:

Setup:

E8500 #2 Q748A212 @ 1.92v
Asus Commando #2 Rev C2
Vcore 1.92v, Vfsb 1.55v, Vnb 1.8v, Vdimm 2.6v, Vsb 1.75v, Vsb 1.2v
Crucial Ballistix 2x1024 (5-4-4-12/5-5-5-15) @ 2.6v
Ocz Powerstream 520W (Vio 3.4v)
Ati Radeon 1600 Pro
Cpu Cooling By Little Devil's Pot @ -112/115°C
Nb Cooling Homemade @ -35°C
Bench Table By Dimastech

Cpu-z @ 5890.05Mhz

Spi1m @ 8.000s

http://www.xtremehardware.it/forum/p...php?n=1327&w=o

I was under 8" at least 3 or 4 times....my best was 7.969 but every time that spi finished system was unstable for capture... i'm at limit, i need more than 1.92v but i don't have any ovp mod for my commando...:shrug:
i'll try with 2003 server and i hope to find the mod :up:
See u soon!

you are so lucky :D

good luck with ovp mod :)

You gotta lucky with E8x00 series CPU's and commando. Some CPU's can't even hit 500 Mhz Fsb.

Dont you guys know he always gets lucky :)

VERY VERY nice 1M Time :D
8.000s.... hrhr

Nice results. :)

Take a picture (high res) of the PCB area where you've already done the vCORE mod, and send me it. I'll tell you. ;)

PS: For benching Spi 1M, you may wish to use Windows XP theme (Luna) instead of Windows Classic. ;)

Thank you all guys... i'll be back with 2003 server :D
Thanks Before, you have a PM!

Congratulations Circuit!
Sorry for the sub 8 screenies but I also like the 8.000:D :clap:

Mmm... i'm looking for ADP3198 datasheet... seem that is like on p5k series...
Just bypass resistance between pin #11 and Gnd
Anyone can try it for me? AHAHAH

nice results :up: , why don't you just try with vdoop maybe when u apply vdroop, ovp will disappear (if I read carefully u only applied vcore mod?)

Oh no, maybe i missed to write it... i've vdrop and vcore mod, but my ovp stopped me @ 1.92v
I tried to turn down vdrop vr but nothing changed...
Another strange thing is that till 1.78-1.8 from bios get 1.9 for exaple on windows but if i set more from bios i get less on windows...ex. 1.85 bios = 1.8 on windows :shrug:
So i need to set under 1.8 and go up with vcore vr but when i arrive to 1.92 ovp shutdown income
I'll try with my spotted pin 11 :D i've 2 commando in case i'll remain with one...:ROTF:

WARNING: This's only my idea about possible OVP mod for Commando studying her circuits...is not yet tested so i can't have guarranty that it work...i need only some opinion :D

On p5b-dlx, when you set vcore lower from bios, ovp also drops :) , when i set 1.75 from bios, max vcore is 1.92 but like when i set 1.65, ovp drops up to 1.88v :p: , had not have time to work on 8500 so p5b-dlx still sits there :)

on P5B E Plus OVP mod 2.1 V
max 2.1v
6.067 MHz

Wtf...great cpu-z! But i can't understand how you achieved only 8" at 5900+ Mhz!!!:D

and i cant see how he runs mem's @ cas3 treu 622mhz :D .
got my Q748A212 today testing , 4.15ghz @ 1.3vcore fully stable lol to easy :)

Is there really an OVP on the Commando? This is the first time i´ve heared about it. No chance to avoid it with VDroop Mod?

You're right, i know...maybe is my vdrop trimmer that have somethings...i'll try it with ma multimeter :shrug:
On my other commando i can go more than 2v without problems... i'll try when i'll load my dewar again...2 or 3 days :up:

Very lucky on your stepps :D

Im Priming my Q6600 right now!

3.6 @ 1.32 Stable so far 3 hours

Maybe they have not used jp strap tweak...

Looking forward to updates ;).

timings... what tha hell?

The cause is because the vcore trimmer value is high in the OVP.
The resistance value which is set raise.


In my case set about 9.8Kohm

ex) Bios set 1.75V + vcore trimmer(9.8Kohm) = 1.984V

Also this evening i tried different settings but mobo goes under ovp around 1.93 i seen also 1.95 but only for 5 or 6 seconds just in time to see 5918Mhz:cool: not validated and mobo turned off and was impossible start it again, on off on off on off :rolleyes: damn protection
:shakes:

huh

mig21 what's up with the timings there man

how did you do an OVP mod??

i got a sweet board as well....628MHz FSB screen on air cooling with E8500....i won't need more than 1.9v for 6Ghz but problem is hotness of this CPU :(..........if this second board i have can also manage -140C i should be ok for 6GHz otherwise probably not :(

I'm out of head...give me some ovp for commando! This's an order! :rofl:

Good luck getting OVP under control cb, we want 6Ghz!

Good clock, sp1m 8.000 :clap:

WOW man , 8.00Sec with Commando and E8500 ...
Way to go !!!!
Now you must and you can go under this 8 seconds .

That's a sweet score...though not relevant, even some camera shots of sub 8 sec would have been sweet, but I'm sure you'll get there soon!

This evening i finished my best OS ever...Many thanks to a friend from Microsoft MVP :clap:
See you under LN2 soon! :up:

what do you mean? :)

:rofl: Sorry, i mean that i completed to setting up my best tweaked OS, i gained 0.108s from my last tweaked OS @ 4Ghz, i can hope in something good on next LN2 Session :clap:

Sharing is caring :D

:ROTF:
First i need to try it myself on high freq, after if it work as i hope, i can share without problems ;)

I think it because I didn't tweak the windows + no use JP Pmem strap.

May be it was a ram bug but I think it would be higher (ram bug too),you can see it through my valid link

I ll show you as soon as I can,I get very busy due to full time job and a baby :p:
