HD7950 revised with reference HD7970 PCB club - Page 34

post #331 of 847
I wouldn't worry about it. Tahiti isn't very memory bandwith constrained. A couple hundred mhz isn't going to make much of a difference either way.

Definitely try with the HIS software and make sure you get the MSI AFterburner cleanly uninstalled.


Not sure what the average is but my card ran well on air with stock voltage right around 1200/1575.


After I water cooled with Heatkiller full cover block with Fujipoly Extreme Thermal pad and Cool Laboratory Liquie Pro I have benched it as high as 1370/1800.

Memory speed does play an important role when you get into high CPU/Memory/and video card over clocking for competitive bench marking. If you are building for speed every component matters and having fast vram does help in benchmark scores and IMO its good for competitive gaming as well.


Some people don't notice the difference between 1600 CL9 RAM in a gaming system and 2133mhz CL9 ram in a gaming system. I do notice it.

Some basics.

It would be great if there was a book on ATIFLash because it has many commands and it is hard to learn them all from experimentation. When you boot into it you will see many commands.

PLEASE post some photos of the PCB. smile.gif

Here you go. Sorry for the poor quality, I just snapped a quick one with my phone. Thankfully there are blocks for this card.

Thanks binormalkilla.

That is the first PCB that the HD7950 TF3 was built on before they changed it to reference HD7970 PCB.

Weren't you talking about GDDR5? I highly doubt that a couple hundred mhz difference in memory clocks make much of a noticable difference either way with Tahiti. Its just not an issue with these cards like it is with Kepler.

I had assumed that you were talking about the GDDR5 on the video card and not the DDR3 on your motherboard.

Going by screenshots it looks like Sapphire Trixx which is a different utility made by Wizzard from techpowerup. He also does Asus' utility iirc.

Just watch out with this tool if you use crossfire, it can crash your pc.

That sucks. I wonder if that is now the norm.

MSI is so inconsistent with what they release. I once received a GTX570 on a GTX470 pcb. It was the same model number as my previous reference MSI GTX570.

Does anyone have the sapphire 950mhz edition on stock clocks? What are you temps when running furmark etc?

My GPU shoots up to 80degrees and VRM1 to ~100-105 just after 5minutes of running the damn thing frown.gif
Also when playing battlefield 3 with high - extreme my temps are ~80.

Case is NZXT Switch 810 with like 10 fans..
