Way too simplistic

Lob some decent Samsung VRAM into the equation that has better timings and can clock higher without running into error correction problems.

Even if you can clock your memory at 1775 this may be slower than using a lower speed where there is no error correction.

Also with the Samsung memory clock for clock it will be faster than other types of memory due to better timings.

Im aware that timings play a role.

And error correction

And error correction

Of course, but that is noticeable in the benchmark graphs and FPS.

Your posts are once again irrelevant because clocking my 290xs RAM from 1300 to 1600 will yield benefits, BECAUSE it is faster.

I think the higher Memory bandwidth helps more at higher res like Multi display and 4K than standard res.

I don't think 320Gb's vs 420Gb's has any effect on 1080P or even 1440P. which matters for an increasing number of people.

Made a large difference in Firestrike and Valley.

Now I don't claim to know much about this, but surely when talking bandwidth it's about more than just the memory, it's also taking into consideration the memory controller or whatever?

I'm running quad channel RAM @ 1866MHz in my RIVE, so bandwidth should be about double that or a board with dual channel RAM. But that doesn't mean that my 1866MHz RAM is faster than 2400MHz RAM does it? Not the actual RAM itself, bu the config/setup it's used in allows for more bandwidth and greater performance.

As I say, not really my area, so may have gotten that wrong, plus it's also arguing over semantics to a degree.

Actually running my Memory @ 1500 vs 1350 helped push my FireStrike score up another 500 Points @ 720P.

So yeah, good point.

Its faster in terms of bandwidth, but some applications might like tight timings over bandwidth.

So what do you think 1250 to 1775 did for me?

Probably about 800 Points, which is a lot.

It's faster to read/write, bandwidth. The ram speed is irreverent without context of the bus width, as 2000mhz ram on 384/256 bus will not be as fast as 'slower' 1750mhz ram on a 512bit bus.

Like googaly said, its arguing over semantics and a waste of time, i'm just pulling your todger as Matt told me you like it.

With all things being equal, then memory type come into play, look at the KPE 780ti, slower ram to a degree but better results clock for clock (was used because worked best in the cold, but still)

Hawaii bios has straps, timing straps. It will increase timings as you increase the RAM clock to maintain a certain latency (higher bandwidth = lower latencies). This is to keep it from crashing and maintain stability .

Its so close to irrelevant that i dont even know why you brought it up Kaap.

Always be wary if Matt gives you a sendspace link, never know what you'll get.
