Frame buffer :)

please friend
what voltage i have to set to FB OCP mod (set a 20K trimpot to 10K???)

Thanks for share

:clap:

are these tested? I did the OCP mod and my card is now dead :(

I did do the GPU OCP mod on mine and it is fine. But I ran into other temp issues :(
I did not do the mem FB OCP mod :shrug: Only Vdimm mod as shown....worked fine.

As to my problem, I was getting artifacting even with stock clocks in 2D (on desktop) below about -80C :confused:
I tried both of the modded BIOSes that Hipro posted :-/

I'll test again when I have more LN2. :)

Very weird results mia, waiting on more news on this.

mia pics of pcb without the resistors?

You don't believe me :shrug:

I'll have to get them later, I'm going to bed :confused:

i just wanted to see it

@Kinc : On the FB OCP mod, wich SMD is more appropriated : 10k or 20k ? :confused:

I measured the SMD that Kinc is showing in the photo and I get 20KOhms resistor.... :)

Had the same thing here.

Check Vdimm readout. What type of insulation do you have?

Where you messure vmem? on caps leg I have 1.67 :| I thought that stock voltage for it it's below 1.6...

I've just measured that "Frame Buffer OCP SMD" too and I get only 5k :shrug:

So mine is 5k and yours 20k, maybe I should replace with 10k :ROTF: :confused:

conformal only ;)

Also, 252CFM blowing ambient air on the ICs :confused:

One time I did see wierd fluctuations on the DMM...but I readjusted my read lead and didn't think anything of it....you thinking mem OCP?

me too
so who took off the 3resisters and still has the card living?
i have a few to try to put back on but after the xannax kicks in lol

Test with the 5k that is there. If you have issues where the card will enter 2D during load it is mosy likely the memory ocp issue.

If you have a card with 20k stock as hipro5 has there is ofc no need to change.

Many thanks for the advices and infos :up:

Just an FYI.

I needed to flash the card with Hipro's coldslow bios before I got the Vdimm upto 1.6V. Without the bios, I got stuck at 1.2V for some weird reason. With all mods (kinc's and hipro's), this new card is flying like crazy ...

Which BIOS did you use, #1 or #2? Is there still issues with memory clocking with #2 BIOS?

Use #1. You don't need #2.

What setting to FB OCP Mod???
5K works fine (LN2)....
Thanks in advance

What brand card are you running Massman?

MSI, both.

Card brand doesn't matter, all these PCBs are reference.

very good
