Commando owns E8500 Wolfdale -> 5320Mhz! SS 1/4HP

nice results eva2000! such a high FSB on this board ;)

old Commando still pwn :up:

This offset is often automatically set to 23 on the latest chipsets. BTW sometimes it doesn't... :shrug: It looks like FSB/dividers related. IIRC, I've tried it with the X38-DS5 and memory read bandwidth was improved by 100MB/s and stability wasn't affected.

New thread for a new bios :) Old 1604 bios results at http://www.xtremesystems.org/forums/...d.php?t=174868

Flashed to 1605 bios from 1604 this time it worked. Asus Commando vcore options only allow next vcore option up from 1.75v = 1.704v idle is 1.7625v = 1.808v idle. So this is it 1.808v vcore on E8500 and this E8500 Q740A493T continues to scale with vcore on Kayl Black FrozenSS 1/4HP!

Bios temps = -9C
Evap idle = -40C
Evap super pi 32M load = -34C
Evap wprime 1024M load = -30C

Room temp = ~29C

System Power Meter load = 265 watts

Woot! You're on fire! Great results! :D

Ouch , impressive E8500 !! what is the fsb max please ?

Congratz for your oc old school "commando" :D

thanks.. definitely on fire!

helps to have cooler room ambients at 29C room temps evap was -40C idle, but at 33C room temps evap was hover just over -34C idle !

E8500 530-535FSB 32M on water with 555FSB max cpuz validation on water. On phase with 1604/1605 bios, Commando is weird past 540FSB. It only is stable on first bios save/exit at high FSB could cpuz validate at 570FSB but on subsequent bios exit/saves - it hangs on DET DDRAM :confused:

Wow, revival of the 965!

The commando seems to play nice with those wolfies, even better than P35.

Yeah Commando seems to like it to a certain extent.. wish my FSB was higher though heh

Go 965 :D

So this CPU clocks higher with Commando than with your Blitz Formula?

Nice results Eva200, but please do not create 2 threads with same setup, dont make anysense you improve a few Mhz and create a new thread :confused:

I merged the threads for you ;)

nah Blitz Formula clocks FSB higher than Commando. I only used Commando as I'm too lazy to prepare and insulate a fresh board. Commando was already prepared and insulated from prior phase change sessions way back heh

Considering with only 9.5x multi, cpu will be clocked to high FSB, either P35/X38 or Commando would need 1:1 divider and Commando is no slouch on 1:1 when properly tuned.. only 8-16 seconds slower for super pi 32M on P35/X38 DDR2 boards i guestimate :)

no worries :)

Nice E8500 George!

From the retail results here at XS, I think I have to get one too, sooner or later :)

The speed on just single stage is impressive.

Ok i see , this 965p is good yet for the 45nm , maybe not the best but good overclocking :)

Yup I'm amazed at what this E8500 is doing on 1/4HP SS!

Yeah oc'ing is nice :D

Super Pi @5155Mhz

Tonight room temps were a bit lower at 25C so decided to push this E8500 Q740A493T a bit more to see how it goes at 1.775v bios set vcore which equals 1.824v windows idle and 1.816v windows load :)

Bios temps = -10C
Evap idle = -41C
Evap super pi 32M load = -35C
Speedfan 4.32 CPU Idle = -32C

Room temp = ~25C

System Power Meter load = 290 watts

Very nice set of screenshots! You need a cascade George...:yepp:

thanks .... yeah colder temps would help hehe

getting awfully close to sub 9min George...congrats but you better not beat me to it :D

oh thats right...my first round of E8400s were terrible, you will have no problem beating me to it :up:

Definitely will be sub 9min once i move to Asus Blitz Extreme + Cellshock PC3-14400 DDR3 :D

9.5 x 542FSB 3:5 903mhz 6-x-x-x DDR3 :)

hehe, that sounds like the correct recipe. i wish i had 900MHz CL6 memory though, i have to puddle through wtih CL7 past 860MHz'ish.

i'm fighting to get sub 9m 30sec with this E8400 on the phase right now with that same recipe just a pinch lower at 530x9 on the P5K3-Dlx, CL7 of course. doesn't look like 9m 30 is going to happen for me tonight though.

P5K3 Deluxe need 0.05v more vcore than Asus Blitz Formula or Commando for oc'ing and prime95 on my E8500 cpus... so maybe P5K3 Deluxe not the best to get max clocks out of for cpu end ?

hicookie did a quick time with a Gigabyte X48T-DQ6

http://www.hwbot.org/result.do?resultId=685943

maybe something to work towards

Utlimately will depend on the max FSB my cpu can handle on 1/4HP SS heh

who knows...it is a monster for SPi at high FSB and i have never had a problem with it at 500FSB+. the maximus extreme on the other hand...is quite the handful north of 500, and doesn't really out perform the P5K3 in SPi from what i have tested. plus the maximus extreme is busy working. plenty of memory to get through this weekend and then it has a stack of GPUs waiting to get their turn ;)

@eva

For Commando & E8400 1604 or 1605 BIOS which one is better?

I have a problem with Det Dram signal on LCD Poster after 500 fsb:S

:(

nice resaults guys i'm happy commando can handle 45nm. How you manage to flash a backward bios? because i tryed too from award flash and afudos, and they didn't let me do it. They post a message when they read the bios version that is older than the one i use and the operasion stops. :confused:
