Anyway to tell what RAM modules my 7950s have?

post #1 of 11
Thread Starter 
So if I remember correctly my 7950s have 2 possibilities for ram options and that one overclocks beyond the stock of 1250mhz and one does not. Is there a way without having to pull my cooler off to tell what modules are on there?

I think what your saying is the difference between the eplida and the Hynix ram modules. The Eplida ram tends to clock lower, while the Hynix ram modules tend to have higher OC's. This can usually be seen on the PCB of the GPU, so I recommend taking out your gpu and checking the RAM, it usually is written right ontop of the ram modules. You may have to cooler on the GPU if it blocks your way.

Either take the cooler off, or search your model number 7950 and see if there is a review on it somewhere where they show the inside pcb of the card.

Within the same revision of the card would they always use the same modules, my cards are all Revision 2, like this one

Is there a speed they should run at, iirc those were the modules that were rated for higher than 1250?

Elpida has both 1250MHz and 1500MHz modules, which means any modules that fail to pass 1500MHz will end up in the weaker pile.

This pile ends up being the Elpida ram in 7950s almost every time. Rarely will they go beyond 1500MHz.

Hynix does not have two sets available, so very rarely do they fail to go beyond 1500MHz.

My Elpida ram clocks to 1700 at 1.5v, so it's not always a bad thing to have it lol.

Not bad at all. You aren't going to bottlenecked by that at all at that core clock.
