ATI 5970 Blocks

[jaredpace]

Hey guys, Your blocks are doing a great job keeping the cores cool, however I suggest you make efficient, direct contact with VRMs for these 5970 cards and get some flow over them (since vrm temp is your/ati's limitation):



1 - 3× Volterra VT1157SFs feed the GPU silkscreened as "U1" (vddc phase 1,2,3 of first 5900 gpu).
2 - 3× Volterra VT1157SFs feed the GPU silkscreened as "U2" (vddc phase 1,2,3 of second 5900 gpu).
3 - 2× Volterra VT1157SFs feed RV870 GPU "uncore" I/O (GDDR5 ctrl?), 2 phases shared for both GPUs. (vddci phase 1 or 2)
4 - 1× Volterra VT232WF feeds the GDDR5 chips their VDD or VDDQ (no way to tell which just by looking).
5 - 1× Volterra VT232WF feeds the GDDR5 chips their VDD or VDDQ (no way to tell which just by looking).
6 - 2× Infineon n-channel MOSFETs (042N03LS + 119N03S) located on the bottom edge of the PCB, for the PLX bridge chip.
7 - 1× AOSMD (AO)Z1024DI low-power integrated buck regulator

Groups 6 & 7 don't report data to monitor temperatures, but these overheating could still cause the card to throttle.
