MSI HD5670 - Update RBE Hash with ASUS HD5670 - How To?

Hi I'm trying to push past 850Mhz on the HD5670 MSI Low Profile.

I flashed Redwood to 850Mhz Core, 1050Mhz Memory as stock speed and it's great. I did modify the card a bit with heatsinks all over it on all voltage regulators. I used Fujipoly 17w/m K thermal pad on the core and it hits about 39C in game under load at 850Mhz just 25% fan. I have some Graphite thermal material coming in soon at 240W/m K thermal conductance to see 30C under load at his speed.

Anyway I know this card could eat it past 850 on the core and 1050 on the memory.

I pulled the hash from the ASUS HD5670 with increased hash limit from default 775,1000 to 950,1250.

I saved the hash and added it to my original bios to have the increased limits. However when I flash it, it basically soft bricks the card where even ATIFlash doesn't detect it on this rig. I pop the card in my Dell Precision and flash back to stock easy and pop it back in this rig.

So just curious how you guy's do/ did it to push past the limit?

THANKS

Set it to Method 2 - No Hash

Set max Hash Core clock to 1050Mhz Core --- and Max Memory Ram Limit of 1300Mhz

I set the 0 state Boot/ 3d mode to 950Mhz core, 1150Mhz memory to not have to mess with it again.

I think I'll set the fans to 100% Min Duty Cycle because I cannot hear them either way.

So far it seems to be pretty happy with 950Mhz Core and 1150Mhz memory. However I do need to invest in 1 to 1.5mm material for the ram. I'm running low quality pads on the ram.

GPU Core quickly hit 66C at 32% fan so I set a static fan profile in the fan setting to keep it cool at these speeds.

At 100% min duty cycle it's stable at 62C or maybe 67C max but its very stable. I added 3 more heatsinks to chips on front and back of PCB.

I think the Core could handle 1000Mhz or even 1050Mhz with the Graphite Thermal Material at 240W/m K. Which is by the way extremely high.

In the future I may use the extreme 1600W/m K material but that's probably extreme over-kill. Since 17w/m K holds 950Mhz at 32% fan -- the 240w/m K may work even better which is great I don't want this card to die it's quite awesome at this speed.
