Should the lack of VRM temp sensors be an issue for air OCs?

I'm asking since the OP wants to WC and is upset with lack of VRM temp sensors.

ekwb lists MSI R7950 Twin Frozr 3GD5/OC BE Radeon HD 7950 Boost Edition 3GB GDDR5 (V276-031R) as AMD reference PCB design checked by EK. definitely should have VRM temp sensors and unlocked voltage. you can also check with the creator of the first thread i posted

Thanks for sharing the photos.

Any photos underneath the VRM heat sinks?

Because they have quality control issues, i.e., fan problems, TIM application. Otherwise I'd lean towards the Sapphire 7950 3L if VRM temp sensors aren't an issue for air OCs. I'm sort of in pickle here.

I can get you those pics in a few days. I have decided NOT to watercool this card since will do me no good. I cannot overvolt the RAM and the cooler does a decent job at keeping the GPU cool. I gain nothing from going water on this card.

The 2L card is the way to go if you don't want to spend the extra cash on the Vapor-X.

I'll prolly go with the MSI coz neither the 2L or Vapor-X fit my case.

As per recommendations, I bought the Swiftech spring steel bracket for my 2L version. When I dismantled it, I was surprised by the vast amount of thermal paste Sapphire applied; the stuff was everywhere. After cleaning up the core and all the surrounding circuitry I applied some NT-H1 and installed the mounting bracket. These changes kept the card at a nice cool 60C max through a 4 hour Skyrim session. Considering that my old 6870 would hit temps of 78C in the same configuration, I'm really impressed. I didn't do a before and after temp reading as I prepared the 7950 while waiting for my PSU RMA to return.

On a side note, when I first tested the Sapphire with the bracket, the GPU wouldn't draw images although the monitor did switch off standby. I suspected that there was too much pressure or the steel had made contact with a circuit. Sure enough, after backing the screws half a turn, the GPU fired right up and was very cool.

ASIC quality image (Click to show)

Wow, in terms of ASIC, is Sapphire using the WORST GPU's they can find? Even my launch day 7950 has an ASIC quality of 74.2%.

Either way, I'm jealous of some of the memory clocks being hit here... my mem tops out at 1650MHz, can't push it past that at ALL. You also have better coolers then I did as a stock card, Kuhler 620 mod is awesome though.

Does ASIC really matter? I can hit 1150/1800 at stock voltages on my 3L. My ASIC is 60.5%.

Hi guys, because our cards doesn't have a sensor for the VRM temperatures, i wonder if the core temp is 68 - 70, how much is the VRM temp ?
