Kyro 2 problem, PLEASE HELP!

[Adrian]

Hi guys,
I have a small problem with my Kyro II from (Prophet 4500 from Hercules).

Well let me get right to the point.

I kind of messed around with my card applying some additional heatsinks on the mem. And by misstake damaged one of the components badly, not the memory. The component is located on the upper righthand side. It's a yellow one with the component number of C39. I would appreciate if someone could tell me what the component number is, that is the one right ON the component, or even better if you know what kind of component it is, please tell me.

Many thanks Adrian

I'm looking at the same component on my card right now. I did some searching but couldn't come up w/ a board trace diagram or something with some real detail.

I would suggest calling Hercules. There should be a phone number on your original paperwork somewhere. I've tried sending them emails a few times and never received a reply. The board design is theirs so they would have the info you need.

By the way do you have the number which is written on the component cause i kind of addad a hs on it so i cant really read what it sais?

And another thing has all of the three yellow components the same number on them?

Cheers

Yes, all three are the same. Here you go:

107A
M0542

I tried to get a good macro shot so you can see the placement. The chip sits with the writing at the same orientation as the C39 marker. Good luck. Keep us posted on your progress!

Thanx for the s/n WillysNut. =)

I managed also to get the s/n from a friend who bought the kyro from the same store as me an his s/n is:
a107am2871

i mean it has to bee the same component, them why do they have different s/n? Cuz your pic. look exacly the same way mine did before modding it,

I will try to get a hardware engineer to look att it later today or tomorrow...

I'll keep you informed

[Adrian]

Back from the engineer with good info =)

Ok, from the beginnig.
the number 107 from a107Am2871 stands for 100 uF on the capacitator. This capacitator is used to balance the Vout of the regulator above (the one you solder the 18kOhm resistor to if you want to OC).
In my case this capacitator was damages which result in overcharging the regulator, and thats the explanation why my computer lock after 2 hours.
the other part of the s/n a107Am2871 is't really important

My system is now up and running :) yippiiieee
While waiting for my 100uF capacitator I replaced the damaged one with a 120uF no problems, atleast no instabilities because of the videocard. Well at the same time as I replaced the capacitator I solded a 18kOhm resistor on to R37 but still it wont OC higher than 183 Mhz. Well I think i have enough cooling on the card, what do you think? As for the GPU i have a Copperfoot BlueOrb (http://www.overclockers.com/tips465) , and for the memory (on both sides of the card) i have 1.5 cm high aluminum heatsinks. And a case with massive airflow, 2 80mm intake fans, 2 80mm blowing out (over the PSU) , the PSU itself and 2 60mm fans blowing out beneth the PSU.

Any tips?
