Nice Patch, it definitely fits as Pizza has a cap section in the OP that needs to be filled out. I cant wait to dice out so I can try these caps out. I was trying to get that NB pot off of Doc from the bloodrage before he left but I was too late and he left for the service. He's going to hold it for me until then and then Im going to throw it on the Katana if it will fit

I dunno... strange though. I too have been to their site before.

*off topic.. Voltera BIOS updates for 5850 and 5870 to unlock GPUv editing :

1. Use these or create your own CCC limits in RBE to allow for more OC headroom


5850 Asus BIOS edited OC limit for CCC

5870 Asus BIOS edited OC limit for CCC


2. Use beta, custom BIOS found here-> http://www.people.freenet.de/BAGZZlash/RBE_124beta.exe

***??????????????
THATS IT!
I was googling for uP semicon and the damn search engine didnt find the upi-semi??????????????
Thanks man!!!!

EDIT:
Here is the datasheet for the 5770 PCB: LFR84FH v1.0

http://www.upi-semi.com/ProductFiles..._DataSheet.pdf

I found the FB and i ll try vmod sometime soon,currently applying vmem mod on my card.
I just hope there will be support for this chip on next MSI...It has I2C interface!

EDIT:I am working on vmod for this PCB so be ready for thank you s!!!


HOLY CRAP!!!
I was so unlucky today!!!While i was modding my card i shorted the resistor responsible for the vMEM voltage...I tried to remove the solder but i have no solder sucker and while i was at iti think i cracked the little resistor...
CRAP!!The new resistance was 6,84kohm.
but GOD was with me today!!!!
I knew the def resistance was 3,52 so i figured the only way to repair the card was to COMPLETE THE MOD!!!!!!I calculated i needed 7,25 kohm VR in parallel so i grabbed a 20k and soldered VERY CAREFULLY!!!!!!!!!
I measured and TADAAAAAAAH!3,52k!!!!!!!
Then i though why waste the effort so i made it 3,38 result is 0.05volts more on SAMSUNGS and 50MHz or more OC!!!!!!!!!!!Now stressing as we speak!!!!

btw i played CO4 no problems!But these SAMSUNGs dont seem to like going over 1400MHz.How much volts should i give them?1,55v is stock.
Would 1,7-175 be safe?

OK, got us updated.

Theo, I just clicked on one of the uP IC listed in OP to find the site.

Also, have you got any progress on the DFI mods? I'm just waiting on you, so the thread can have the privilege of hosting your pics and mod points.

Hi guys I've looked at the vmod you've done on here for the non-ref XFX4890:



But mine is a slightly different setup. The chip on mine is a uP62204NJ VCB99H and where the resistor should be for the mod (shown by arrow) is missing; just the holes in the PCB are there. Thought mine was the same. It is a XFX 4890 ZSFC. Bought it thinking it would easily clock to 900mhz but can't even reach 890 without it locking up.

Any suggestions?

Post up some pics of your IC. Try to get close and clear pics if you can.
