Who tried winchester (90nm) with Phase cooling?

[jinu117]

And got it working okay?
I know you big guns are so into FXs... but some of us underdogs with phasecooling want to try these 90nm which are more affordable to play with So far, I've had no luck of 2 K8N Neo2 booting up with prommy running when evap temp is below -20 or -30c... I believe Same is true with A8V from some other member questioning recently.
Is there any big dogs that have tried these measly 939 3200+, 3000+ or 90nm 3500+ with phasecooling yet?
Would appreciate any tips, helps, etc.

PS) For MSI I tried 4 diff versions of bios... till I gave up. (that was on 2 boards :P)

PPS) If I just attach the exact same setup with air cooling... it will boot up just fine.

I'd like to know the same, seeing as Winchesters are faster per clock.

I think Onepagebook has his at an easy 3 GHz (something like 1.45v) and its ripping off 28s SuperPi's.

im not a big dog by any means but i do own a phase change unit and a few 64 chips so maybe i can help...

have you tried using a sep psu? the system should boot with the promie running seprate from the system so try taking a seprate psu and running the mach unit off that and see if it boots? i use a seprate psu myself and i have zero problems... maybe the reset hold button isnt letting it boot? i know every mb ive owned isnt compatible with this mach unit so it doesnt surprise me that your having troubles... good luck

peace perc,

Hi

I currently am using an A8V Rev2 with a 3200+ and the board will post fine with the evap temp all the way down at -52c (at default clock). I do have a prblem with the Mach2 control board not powering up the mobo however but that is fixed by flashing to the lastest bios which i haven't had time to do yet.

Since stupid XP BSOD's at boot now that i have a new mobo in I need to reinstall before i can flash the Mach2 and try overclocking.

FYI in the bios at default hardware monitor reports the cpu temp as -20c

[jinu117]

So A8V does read - temp... good!
Well, my prommy was on separate PSU to begin with In fact, I am on my 3rd or 4th mobo on A64 with 4th or 5th CPU. (not counting 2 each of K8N Neo2 and 3200 winchester I tried).
Gonna cancel my order for another clawhammer I was gonna fool around with and gonna give 939 a shot .... again... A8V Rev2 eh? Know any place where I can get it not worrying about other revision.

[Psilonaught1]

i'm pretty sure you can run the Mach2 normally with the A8V provided you flash to the latest A64 firmware - no need to use 2 different PSU's

btw, Psilon, welcome to Xtreme.

I got a 3200 that as soon as it hit -20 bang no post this is useless with a prom that starts at -30 I updated the bios everything in the end I sent the 3200 back and dropped a 3500 newcastle into my msi ran no probs at all

[Cashman]

Hey there Fatty,

Did you ever get this sorted mate?

My Mach II GT is working fine but when it cools the 3500 Winchester the PC wont start, same as you!!

Even with the Mach II attatched (but a HSF on the CPU) the PC boots perfectly... either the Neo2 or the Winnie just doesnt like the cold??

This is soooooo ANNOYING!!

[jinu117]

Now countinng 4 boards and 3 CPU, I give up. Until someone fixes bios, I don't think I will look back for a while on winchesters. One thing for sure, it boots up fine when you do cmos reset whichever temp it is at. In the mean time I think I will just get a 939 newcastle and fool around with it. Shortly will be putting bunch of things on sale forum to recover some cost. Not into 15% restocking game.

[fatty]

I have gone back to newcastle 3500 the winchester just wouldnt have subzero on this mobo??

[Cashman]

i think I may have to do the same!

[`schr0et]

did you have a fan plugged into CPU header?

[jinu117]

did you have a fan plugged into CPU header?

Which does absolutely nothing good in all 3 types of mobo.

Okay... I do start sounding bitter.. don't I ?

[`schr0et]

weird my K8N NEO2 wouldn't boot without the CPU fan header having a fan plugged in, when I plugged the CPU fan header it booted fine.

[jinu117]

Hmm... maybe just maybe I will give it another go... but I am so sure I had the fan header connected to real case fan :P (Lian-Li case).
Still didn't end up selling any so I might have few hours to play.

try the lastest bios which has been modded - http://www.lejabeach.com/MSIK8N/k8nneo2.html

[jinu117]

Oh... lord... was just gonna RMA... Okay... there are few options I "might" like... let's give it another go....

[Cashman]

Shroet, how did you get yours going on the mach II GT? I assume yours is a Winchester??


Jinu> any joy mate?

[`schr0et]

Mines was 130nm when I didn't have fan plugged into CPU header = no boot
fan in cpu header = boot

I get my 90 nm 3500+ on monday along with a new K8N NEO2 so I'll report then.

No Go...

[fatty]

Ok bugger the winnies till msi come out with a better bios??? dunno my mach2 gt works a treat on 130nm fan or no fan plugged into the cpu header getting 2860 so far out of my 3500 newcastle maybe i'll push for more???

[jinu117]

My initial impression of 3500+ 90nm on air was 2.55-2.65ghz prime stable on stock air cooling. I remember my 3200+ 130nm did about 2.35-2.5ghz prime stable on stock air.
This 3200 is chugging around 2.75-2.8ghz prime stable depending on ambient on baker modded mach2 (oc-rookie's :P) that is running at normal fan speed :P All things stable (non-prime) is about 2.84ghz or so on this 3200.
Just from guestimation, with our cooling I wouldn't be surprised to see prime stable 3ghz with 3500 90nm if it can boot up :P

I was thinking of get a Winchester to go in my Prommie
Has anybody tried to use a 2nd PSU for the Prommie, then fire it up before it hit's -20 while tapping insert (so the chip boot's at a lower speed) entering Bios and wait for the Prommie temp to drop, save and exit and boot at OC'ed speed or does it not work if you reboot at over -20 as well???

[jjcom]

why not just boot the computer while its not in neg temps? Wouldn't that work? I'm not an expert so this may sound stupid, but hey I'm here to learn
