Wondering where vrms are on my card

[Guest]

Hi, I have been overclocking my gtx 460 whdi card and I was just wondering where the vrms were? Are they all under that heatsink to the right (Red)? And is the blue my ram?

I'm wondering for educational purposes and also because I've heard the vrms on graphics cards are the thing to worry about when overvolting. Currently I am currently using msi afterburner running 1.15v, 900/1800 and 2340 Ram. I modded my bios from the original 1.087V limit.

The ram runs flawlessly at that speed with 0 artifacts. It took me that much volatage to get it stable at 900mhz, and I want 900mhz because it allows me to get my perfect 60fps in one of my favorite games

I only play games about 10% of the time and will only run this profile when needed. The card has two case fans blowing on it and my GPU temp never breaks 57C under full load. That being said would this still be a safe voltage to play at in your opinion?

My Specs (24 hour prime stable):
Corsair Carbide 400R Case
Asus P8Z68-V Motherboard
Intel i5 2500k @ 1.41v, 5.2ghz
Corsair H100 Watercooler
16 GB Corsair Vengence 1600 CL9 @ 1.575V 1866mhz 10-10-9-24-1
600W Corsair PSU
256GB Crucial SSD and 3TB WD HDD

the blue circle is VRAM. i believe the one with heatsink is VRM

I think the heatsink is for the VRM. So the VRM is below it. And the one around the GPU is I think the RAMs.
