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

[eva2000]

Commando takes on Wolfdale 45nm - E8500 -> 5104Mhz at 1.60v !

Let's see how the old 965P C2 chipset holds up for E8500 Wolfdale

Asus Commando takes on 45nm Wolfdale E8500 cpu. I decided to go back to Asus Commando as the motherboard was already prepared and insulated for Kayl Black FrozenSS 1/4HP phase change cooling.

First I installed my E6700 cpu on Asus Commando, so I could flash the bios using biso Ez Flash from 1501 bios to 1605 bios. Then I installed E8500 but system wouldn't boot - stuck on CPU INIT on LCD display. Then I decided to reinstall E6700 cpu, and flash from 1605 bios to 1604 bios, then reinstalled E8500 and now it booted up!

Not sure if it's bioses issues with E8500 but when I play with high FSB, only the first reboot from setting high FSB in bios will load into windows, subsequent bios exits result in system boot hanging with DET DRAM displayed on LCD display ? Never had such an issue with E6600 or E6850 on Asus Commando with 1501 bios. Definitely, bios and/or memory related I think as I got a higher FSB with 5-5-5-x than 4-4-4-x.

Anyway down to fun stuff

Some CPUZ max capture screens

570FSB not stable, still have to figure it out - memory or bios related issues.



@4800Mhz at 1.480v idle



@4940Mhz at 1.528v idle



@5003Mhz at 1.560v idle



Kayl Black Frozen SS 1/4HP power! Bios says -25C evap says -42.2C heh

@5104Mhz at 1.600v idle



Loose memory 5-5-5-18 Super Pi 1M



Kayl Black Frozen SS 1/4HP power! Bios says -21C evap says -40.2C heh

--------------------------
Some Super Pi 32M action

@4850Mhz at 1.584v idle

Bios says around -24C while evap says -41.4C idle and -39.8C Super Pi 32M load. Speedfan 4.32 takes too long to load, but did do a Systool dual 32M Pi load test and reported cpu temp as -37C idle and -10C load.



Not bad for 1:1 on 965P C2 chipset compared to my E8500 @4791Mhz - 9.5x504FSB 4:5 630Mhz 5-5-4-9 run @9m 48.360s

[eva2000]

E8500 @5007Mhz at 1.68v idle

First time ever Super Pi 32M at >5Ghz with a Core 2 cpu! Best 1M & 32M time I've done personally as well

Nice work as always. What was maxFSB of this chip on air and on SS Phase?

[eva2000]

On water around 535-555FSB for 32M to cpuz validation on Asus Blitz Formula P35 board. On SS is what you see above but could be bios issues holding me back on Asus Commando 965P C2 chipset.

Nice job eva

I love my Commando one more time

[before]

Very nicely done George! Did you mod MCHBAR registers?

[eva2000]

Thanks guys..

before, yup did the usual tweaks of mchbar unless you have some new ones to share ?

E8500 @5282Mhz at 1.704v idle / 1.696v load

E8500 managed max CPUZ Validation of 5282Mhz at 1.704v idle! Bios set vcore was 1.75v. 1.7625v and above vcore jumps in vcore alot i.e. 1.7625v bios set = 1.808v vcore and scales up from there so dangerous territory for E8500 i suppose ??





Max 1M @5104Mhz at 1.704v idle / 1.696v load



Max 32M @5033Mhz at 1.704v idle / 1.696v load

Lookin' good Eva... I have no idea how the results looks compared with P35 I must admit, but the 32M seems quite fast I belive.

[Viss]

Very nice Eva, Commando is stil good fun. Im using bios 1605 with E8400, maybe that one wil help you for FSB. We want sub 9 in 1M

Thanks - yeah probably a good 8-16 seconds slower than P35 DDR2 ?

That has to be the cpu talking 590FSB! nice!

1605 bios won't boot my E8500 for some reason stuck on CPU INIT, 1604 works though

[Viss]

Thanks for that bios info, wil try E8500 soon and wil let you know if i get same thing with 1605.

[Oliver]

Good job George and not bad at all...

Keep pushing it.

[PcCI2iminal]

nice again George

Commando ftw

[eva2000]

Thanks for that bios info, wil try E8500 soon and wil let you know if i get same thing with 1605.

let us know how that goes

Good job George and not bad at all...

Keep pushing it.

thanks

nice again George

Commando ftw

Yup saw your results on Blitz Formula + DI ...130Mhz PCI-E! nice

[dnldnt]

nice clocks eva, keep it up. can u check your pm pls?

[eva2000]

nice clocks eva, keep it up. can u check your pm pls?

not hard to find - use search for keywords = scythe infinity mount mod

4th or 5th result listed is it

[Viss]

let us know how that goes

No problems here with 1605

[nachthymnen]

This time you have found a very good cpu!
I remember your bad QX9650.
Simply amazing!
Congratz

[s0lid]

Insane results and clocks!
These Wolfdales have just insane overclocking abilities

I just wish than i would have a SS :/

[dinos22]

how does this FSB compare to newer chipsets
there seems to be something odd going on with this C2 revision chipset as per loco's thread

try that 1605 bios again
maybe second time lucky since it works lol

great results and fairly decent speeds i must say

what's this MCHBAR stuff you guys are talking about again heh

[Viss]

Pmem id guess.

[eva2000]

No problems here with 1605

Yeah might try 1605 bios and and see if it helps.. according to memset my commando is 965P C2 chipset too

thanks.. yeah QX965O not that great compared to these E8500!

Thanks to Kayl's Black FrozenSS 1/4HP to think this unit was originally created for FX-60 s939 days to be tuned for high heat loads but not too low temps to combat FX-60 s939 cold bug hehe

So far FSB for me hasn't changed much actually a bit lower on Commando than Blitz Formula for max bootable cpuz validation 540FSB vs 555FSB on Blitz Formula. Mchbar tweaks been documented on i4memory.com for past 6 months dinos http://i4memory.com/showthread.php?t=4268 thanks to JP's research

Not really; I'm focused on P35's. http://www.xtremesystems.org/forums/...1&postcount=48

BTW, I'm sure you know that, but offset FED1403Fh set to 23 is the most important; and still is on newer chipsets.

x38/x48 too?

what benefits do you get from it performance wise
