My power supply doesn't have 12 pins for the CPU, only 8 as 4+4. To be honest it's made no difference to me since I am not overclocking anyway.
Either way I've been playing around with this build and it's a beast! My only tweaks so far are as follows:
Enabled EXPO for RAM so that it runs at...
Finally was able to put it together and it works just fine with only the 8-Pin EPS-12V connector. I set the CPU to run in 105W ECO mode and undervolted the 3080 a touch, now I need to spend some time tweaking this beast. Thanks for the suggestions and help everyone!
My older PSU doesn’t have the extra 8 pin tagged for the CPU, I only have a single 8-pin that can be broken up into 4+4, I suppose I can use another PCIe connector as the 8-pin and use 4 of the 8 CPU pins as the 4-pin if I had to.
This is the max 8 pin connectors for my 650W power supply which...
There may be an obvious answer to this but my power supply only has a single 8 pin CPU power cable while the motherboard has 8+4 pin sockets, I can't imagine that a standard 7900X needs 12 pins of +12V but the manual isn't very helpful (connect 4+4, or 8, or 8+4). Is there any reason to use 8+4...
Just picked up the rest of the pieces after seeing the release of the timing and price for the X3D, here are the remaining picks:
RTX 3080: Installed it temporarily in my old rig, it runs great with a reduced Vcore curve and a lowered power target. Plan is to sacrifice a bit of performance in...
Re:Intel, the main reason I want to go AMD is that I can run the CPUs in 140W mode and retain most of the performance. I could save a few bucks by going Intel but then I would have many years of sitting next to a space heater!
Good point regarding the PSU: mostly I put that model as a stand-in...
Good catch on the RAM, I will make the change!
I guess the other option is to look at the 12GB AMD cards (6700xt or 6800), the problem is that all AI/ML runs on CUDA.
I could also take the RX 470 from my current system temporarily. I'm just not seeing GPU prices going down much farther from...
Interesting, would 8GB VRAM matter at 1440p though or is it only a concern at 4k?
V-Cache should be interesting but I suspect it will push me out of my budget for marginally better performance The 7900X3D also looks like it will have a wonky configuration where the the extra cache is on the...
Edit: I can't believe I have been an AT Forum member for nearly 22 years!
Currently running an i7 3770 (non-k) that has served me fine since forever but is definitely getting long in the tooth. I had been wanting to upgrade in 2020 but prices spiked and I decided to make due with what I have...
4.5 dB less sensitivity is a huge difference in a receiver (2.8x less sensitive). Path loss is quadratic to distance so to have 2.8x as much power, you need to be ~ 7.8x closer to the receiver for equivalent performance. There's possibly some issue with the specific phone they have or their...
I just found this thread as I had posted something very similar in the memory and storage forums.
I can definitely see something like some near-future platform that would have 8-16 GB of on-package HMC, 128-512 GB of XPoint and TBs of spinning rust or SSD depending on how much you're willing to...
Yup, you're right about that, my mistake.
Nonetheless, I would think that they could make some significant changes to the memory hierarchy in the near future. Smaller amount of HMC on-package for lower latency and higher bandwidth than DRAM, then put some 3D-XPoint a bit farther away in larger...
