severe Mach II problem

[serialkiller]

Hi there :p
Well as of today i can call myself a Mach II owner, yet not user :(

After installing everything and connecting all that was needed, i tried to fire up the mach II, which worked but with one problem:

on the LCD i get the message:
'Boot Loading
Waiting'

whilst the compressor is running at full speed...
I dont get any other messages and my pc just wont boot...

When i disconnect the molex from prom -> PSU i see the fans spinning for a quick sec and then nothing (prom still running though)

When i hold the molexes together and try some combo's i get the mobo to start up, but it immediately shuts down and starts up again, and on and on and on....

This process makes the diagnostic led blink about 2times a second and makes my led fans blink aswel instead of making em light up entirely...
Same goes for my keyboard leds...

Now how can i solve this somewhat irritating problem?

im using a TSP 550W

Have you tried updating the firmware? Had the same problem and this fixed it.

[TheDude]

Does the mobo boot ok on air?

[serialkiller]

hehe i figured it all out now
(with the help of xtremesystems :) )

Firmware of the prom had to be updated: the evap head did not heat up (!!) making condensation an easy aftereffect and possibly killing my mobo :(

Mach II now works like it should, only i need a new mobo :p

[serialkiller]

im having this new problem now, the prom just wont startup with overclocked settings or after a restart...

I have a 2500+ that could boot into windows at 2500Mhz and worked rock stable at 2350mhz (never tested beyond that)

Now the prom wont even start when settings are at 11*200!

Anybody has some advice here?

[serialkiller]

Bowman, TheDude or JC still online?
They are the guys that seem to have most experience with the phase change stuff so probably they know what is going on here aswell :)

[JCviggen]

if you're on an EPOX board its a normal temp.... they use in socket reading... especially with the heating element on the back of the mobo!

you can only tell if you have good contact by the OC you can reach ;)
bad overclock usually means bad contact. maybe you should add some spacers to the screws on top?

-47 load seems like a good temp!

[serialkiller]

heh well i tried to fine-tune (woew fancy word there :p) the contact and now i have -47 on evap and -4 on MBM

I think that's fairly normal?

[JCviggen]

-4C sounds a lot better, but you need to get that OC up m8 ;)

basically you just need to play with it a while you know...when i first started i also had a terrible time getting everyting right, especially the contact

after some time you get to like it more ;)

[serialkiller]

hehe i noticed and so did my 'old' 8rda3+ =)

Well i think thats the fun of working with computers though, getting an impossible problem and fixing it yourself (with ofcourse the needed online help eh ;-) )

Think i can manage to cranck the 2500+ up to 2.7 or 2.8ghz though i have a much higher oc'ing proc waiting to be frozen :p

Its a 2700+ AIUGB doing 2500mhz on air with BS cooling and bad ram :)

[TheDude]

Are you saying that the prom will not run at all? It should start before your mobo does...so the clock should not matter until it hits the temp where your mobo switches on. Does the prom evap head get cold when not connected to the mobo?
I'm not too clear on exactly what you mean...sorry...please clarify for me...thanks. ;)

[serialkiller]

basically the probs are somewhat solved right now, all i have to do is optimise the cpu contact :)
Thx for the help though ;)

[TheDude]

OIC....I was called away from PC in mid reply and looking at the post times...it seems I missed a lot! LOL
Glad you got it sorted out. :D

[serialkiller]

hehe no problem and again, thx for offering to help me :)
the only thing im worried about now is the rather high temps i get from MBM.
I know its relatively normal to have higher temps in bios or such than with the evaporator but still...

My Vcore is now 1.90 on 8rda3+ (socket sensor)
Constant 100% load
Evap temp = -30°
MBM temp = 4°

[JCviggen]

You know, I had temps between 5 and 15C load on an 8rda+ with a 404A prom.....the socket reading is just...well...not very accurate. if I added a fan to cool the mosfets my CPU temp dropped 10C :rolleyes:
the ABIT NF7-S gave me a little bit better readings but still no core reading. But about 10C lower than the epox anyway.

Thats one thing in favour of Intel, at least most mainboards have a somewhat reliable temp sensor... which reads the CPU, not the socket

[TheDude]

Yeah...I don't put much faith in those temps at all. It's like the idiot lights on a car dashboard.....by the time you see that something is wrong, it's too late! ;)

serialkiller......

You'll like that AIUGB 2700+. Think you'll find
it has some legs.

I've got one that I bought from Caprid that will knock
right on 3 Ghz stable.

This is under a Mach1 that I purchased from isp.

Using an Abit NF7 Ver2 and TwinMos 3700. This NF7
gave me 250 FSB out of the box (10 X 250) without
mods.

Using air cooling to test it out.

I 'bout peed my pants.

[serialkiller]

hehehe :)
hope it performs well, it did on air though the core is missing a tiny fragment :(

so far i did not succeed in getting it to work properly, mobo is giving me post code FF again :(

With the barton no probs, but now with the 2700+ i get FF all the time and the only problem i can think of is the proc itself

Just hope i didnt ruin the board by putting the 2700 in :p

[Popcicle]

FF is definate CPU code.

If you get this right up front and no POST
sequence at all it means the CPU is failing.

If you can go all the way thru the POST sequence
and FF is the last thing reading on the LED....
it means everything is honky including the CPU.


Pops.

[serialkiller]

well i noticed on the new board that the socket clips are a bit loose a the bottom of the socket...
Had a bit heavy aircooler on it at first :(

I can second this, I had temps over 20*c with my 8rda+

The 8rda3G just reads 0*c the entire time.

[serialkiller]

heh got my 2 8rda3+ into RMA
Think epox already made a fortune out of me, hell i like bought 7 or 8 epox'es :p
Seems to me i better start working soon so i can pay some new ones :p
