yeah, twisted indeed, but the bios does work reliably 8-)
Just as a quick KNOWN bios guide:
9500np will take: 9500/9500Pro/9700/9700Pro bioses (depending on 2x4 or 4x2 ram configuration, soft/hard mod).
9500Pro will take: 9500Pro bioses.
9700np will take: 9500np/9700/9700pro bioses (depending on soft/hard moded (why would you do that to a 9700np, though? heh)).
9700Pro - Same as 9700.
9800 series - Unknown. Is the core different or is it just bios settings and core revisions that have made it better?
-
thx for the fast replies, so i will have the choice between the 3 9500Pro bioses :
-Warp11 : hynix
-trick : infinion3.3
-Darkmage : infinion 3.0
so far i've tested without any difference in o/c with warp11 and trick , i don't have the balls to flash the Darkmage one, but i'll try if it can work :)
-
Anybody know where you can have this done at ?
-
Not likely to be a difference really, xigfrid.
Most of the effect is seen on 9500np/9700 cards with super hot ram chips..
Napalm - see if you can get a heat gun from an electronics repair shop. Other than that, possibly the tech center at a university...?
Dont do this unless you're ready to end up killing something, though.
-
What's the max temp the BGA mem chip can take ?
I would rather have this done professionally but i got dead card i can practice on.
-
find a lot of radeon bioses at http://www.ocfaq.com/softmod/bios.php
napalm: check the datasheets - samsung ones are easy to find
-
The chips on my Ti4400 are GC2B 214's.. R9700 has GC2A 214's...
hmm...
8-)
I would say about 70c max, but I might be off.

ABSOLUTE MAXIMUM RATINGS
Parameter / Symbol / Value / Unit
Voltage on any pin relative to Vss / VIN, VOUT / -0.5 ~ 3.6 / V
Voltage on VDD supply relative to Vss / VDD / -1.0 ~ 3.6 / V
Voltage on VDD supply relative to Vss / VDDQ / -0.5 ~ 3.6 / V
Storage temperature / TSTG / -55 ~ +150 / °C
Power dissipation / PD / 3.3 / W
Short circuit current / IOS / 50 / mA
~150°C max ???
-
thats storage .. not running
-
That's the temp, not running temp.
Where's that hot air gun now...
-
STEvil. As u see, GC2B and GC2A are pretty switchable - mine works fine, although i haven't tried some serious oc yet... Just today soldered back 2 basic voltmods and have done Vref... Tomorrow will be a great day - first benches with Vapo XE:)
-
I gotta say.. This is THE MOST Xtreme kind of modding I´v ever seen.. I mean.. U got to love it.. Killer work there ALT-F13..
Only proves the europeans are that much greater :-D-............
-
I was just about to looking for my heat gun, but someone messaged me on msn with some cryptic message about a beta of a big ring used to signify angels being really close to the sun...
58 hours remaining...
I'll go find my heat gun now 8-)
EDIT
Whats the difference between the GC2A's and GC2B's in the data sheet? Stick the better chips on my 9700.. hehe.
-
Ive just finished doing some initial experiments that have turned out pretty good.
Ive just been using normall solder to put the chips back on, I think ill get a much higher success rate using liquid solder.
Ive only tested on dead cards so far, but ive got the tequnique down pretty good.
if anybody else in the UK has a potential ram donor or a card missing a ram chip can you PM me as I need some more patients (victims)
I dont want to try any upgrades just yet as it would be a shame to kill a working card (I dont want the blame) but If I can get a few succesfull repairs done ill try some upgrades (my 9700NP needs better ram)
Hehe, this is fun.
-
Man, I wish I had the skillz to try something like this ;). Maybe eventually I will get there, but atm soldering two wires together is the extent of my skills, lol :D.
-
Ok, finally pics of process are here. For now only unsoldering:)

Electric oven - tool we've used.

Removing the chip - it is unseen on the photo but card is literally boiling.
http://alt.modlabs.net/4.jpg
Chip removed. Sorry for bad quality.

Unsoldered chip in the holder.
-
I bet that makes one heck of a burn-in process for the card.. lol 8-)
-
rofl. Since we've resoldered chip cards max mem clocks raised from 380 to 400-402, but i've also done Vref mod up to 1.5V. So dunno what helped:)
-
So after all this talk, has anyone taken 2nS ram and attached to R9800 and been successful????? BTW, Alt F13....this is one of the MOST Xtreme mods I've ever seen...very cool.

hey guys, i got a PNY Gf4 ti4200 , and its like almost dead but not quite, i have ? marks all over the screen. Would this be a memory problem or a GPU problem? i wont to see if you guys knew, thanks
-
I've heard of changing chips back in the Slot 1/A days.. but that was way back when.. 8-)
Peen - core?
-
yeah it probly is the core , unfixable
-
HUmmm..., this kinda pisses me off, since i was already planning to mod my ti42, with some ti46 chips..., but whats been holding me back is that i dont have the tools to unsolder the chips, and the idea that my card is burning up in a oven is just not my kind of fun...
ALT-F13:
But still nice to see that it will work though ;O)
do you have any idea on how to unsolder the chip, with house hold equipment ?, like a regular soldering gun and stuff ?...
i think that the mem chips on the ti cards only have pin's on the sides of the chip, but not sure....
(Typically me not to dare the moves i think of..., ahh its nice with some self-petty *lol*)
cheers all the same...

BGA = square
TSOP = Rectangle with side pins
They've come with bith, I believe.
Heat gun and good tweezers might work...
-
TSOP-modules should be much easier to unsolder, right? Maybe I should switch my crappy clocking modules on my MX440 :) They only do about 530 without vmem-mod, with a couple of modules from a Ti4200 they should do at least 600...
Hehe, well it's a project for the future, must find somebody who's good at soldering, my skill stretches no further than my nose. :)
