SK Hynix GDDR7 Memory Overclocked to 34 Gbps on NVIDIA GeForce RTX 5070 Ti
As a GPU supply chain gets regularly updated, NVIDIA quietly added a new memory partner to its GeForce RTX 50 series lineup, bringing SK Hynix on board alongside Samsung for GDDR7 modules. Early mentions suggested that SK Hynix memory would appear on standard RTX 5070 cards. Still, the first sightings were on RTX 5070 Ti models, especially in China, where these cards have arrived ahead of other regions. Users on Chiphell and Baidu, verifying their GPUs with GPU-Z, discovered that the SK Hynix chips, which officially run at 28 Gbps, can be safely overclocked to 34 Gbps. This shows that switching to a second supplier does not hurt performance or overclocking headroom, so enthusiasts can expect the same headroom they've enjoyed with Samsung-sourced modules.
That said, some owners have encountered an obstacle when cross-flashing BIOS files with SKUs that use Samsung memory. Flashing an RTX 5070 Ti BIOS from a Samsung-equipped card onto one built with SK Hynix memory sometimes prevents the GPU from booting. However, dual-BIOS designs let users switch back to factory firmware and restore normal operation without too much fuss. As VideoCardz pointed out, TechPowerUp's BIOS database indicates that current firmware versions from various board partners already include support for GDDR7 modules from Samsung, SK Hynix, and even Micron. This suggests that these flashing issues aren't simply a matter of unrecognized memory. It could be related to board-specific power settings or other configuration quirks, with every GPU maker designing their boards differently, yielding possible errors if the firmware is swapped. Since SK Hynix-based cards run fine out of the box, most users won't have any reason to flash different firmware.

spurn it, churn it, burn it.....
Light 'em up if you got 'em, simulate if ya don't...
Shall I continue ?
hahahahahahaha....:D
with GDDR, many time, you have a face value stable overclocking, but it hurts the performance because it uses all the powerful error correction which however have a penalty to pay....
No idea about the normal 3Dmark score ...
Also, didnt we report the hynix chip to be running hot at 28gbps already?
34gbps would be concerning on the long run.
They're all pretty similar nowadays, it all depends of silicon lottery imo.
As for benchmarks I only get around 80 points more in SpeedWay. I am just going to assume the reason I can't get any higher performance with the extra +1000, is because of the 256-bit bus/GPU itself. Or maybe it's just my card. Most people don't push their cards beyond +2000 as they don't know how to unlock the extra +1000, so unfortunately, there is very limited data available to me to compare my results.
All I know is, the drivers are a mess, even 4 months after launch I find so many display issues in-game, stuttering, black screens etc etc, it being so bad, you might just think your GPU is busted until you use Cyberpunk as a baseline because it receives fixes often, all this and they are already prepping Super variants of the 5080/5070, it's beyond disgraceful.
Or both.
What pressure, this was just me being sarcastic,:roll:
