Weak Overclocking Potential with RTX 4090 Gigabyte Gaming OC

[Super panda]

Hi,

 

I recieved my RTX 4090 Gigabyte Gaming OC yesterday and started playing with overclocking. I noticed I can't push the memory more than 1000 Mhz on Msi afterburner before I start noticing artifacts and crashes. The maximum stable core clock with this card is 3015 Mhz. Did I lose the sillicon lottery with this card ? I remember I was able to Overclock my Gigabyte RTX 3090 Gaming OC much better. I can still return this product. If I return this product, which RTX 4090 should I buy that has good overclocking potential ? My guess Asus Rog Strix RTX 4090 OC ? I wish everyone a good holiday and look forward to get some answers !

 

Thanks

Different architecture. Clockspeeds are only comparable on the same arch, with the same core/CU count.

Thanks. Yeah while that's true, I remember it Oc'd the memory much higher.

Offset? Or actual clock? The 3090 Gaming OC starts with a 1219Mhz clock for 19.5Gbps effective, the 4090 starts with 1313Mhz for 21Gbps effective. 3090 spec here and 4090 spec here.

1000 Mhz offset on memory on my rtx 4090 is the max stable memory OC I can get.

My OC results seems a little bit weak compared to what I expected myself

The days of significant overclocking headroom on GPU's are over and done.

Yes, but they seem to have quite a bit left in vram and headroom to undervolt without losing a ton of performance.  Being said +1000 is really good anyway.  I get 1.1TB/s on my 4090 at +1000 memory.

Thanks for your answer. How about your core clock on your 4090 ?

Haven't really pushed it I undervolted and did a lower power target.  It's about as fast as it was out of the box but at about 380W.  I believe it is just a bit over 2800Mhz.

The 4090 Gaming OC is about as good as it gets. Actually I think its the most popular choice in the overclock.net forums. You might get a card that clocks slightly better but I wouldn't bother with that because there is very little performance difference between them. If you are someone that is chasing clocks, I believe at the very least you should look at a water block for the card.

Thank you for your answer. I see that you have a tuf oc 4090. How is that card for overclocking ?

It is used for work so no OC on that thing. I also have a gaming OC and I would give it the edge since the memory cooling is better but I wouldn't worry about the mem temps on the tuf either way. 

 

You should post your questions on the 4090 owners club thread in overclock.net. They have members who have multiple overclocked 4090s so they'll probably be able to give you a better answer. You'll also find high power limit bios for the 4090 there.

This isn't the brand you just didn't hit the lottery is all, all cards will perform differently. My gaming oc does 270/1600 stable, the memory does go to 1800 but I pulled it back for everyday use, however this is nothing more than I got a better card. Memory clocking seems to average for most cards between 1000 and 1500, more you got the lottery, but the performance difference is not much anyway, higher scores in benchmarks but that's really it. No point in returning and chasing as the same could happen on a strix oc for example
