Discord overlay seemingly crashing my gaming PC. Have turned off and will see if this fixes it.

Reviewers have started getting the 4090FE. It'll be interesting once benchmark videos come out to see if they are as good as advertised.

Jay got his hands on a ROG Strix 4090 and it is massive. Almost as long as a PS5. Dunno how many people are actually going to have cases big enough to fit it.

That was nuts when I saw it. You can just about rule out any mid tower. Looks like my h710 is fine but may look at a Lian Li or something next time that has not only more room but more fan options.

First thing I think when I see how ridiculously big those cards are is that you'd probably want a custom loop instead

Does anyone else find Ed to be a bit of a vapid knob?

I watch him a bit but more out of bemusement.

Fractal Define R5/6/7 has plenty of room for them

Thanks for sorta reminding me, going to keep an eye on the Meshify S2 XL which I couldn't get my hands on last time.

Moving house next week so have been doing some clean up. Found my old GTX680. Nothing to really do with it these days but felt weird throwing it in the bin.

I done that afew years ago, found my 480 with all the parts. 3 card sli adaptors lol

Yeah finding boxes of parts, cables and adaptors of sorts that I'm sure seemed worthwhile to hold onto at the time lol

Hey, I KNOW I'm going to find a use for that Geforce 2 GTS I have in a box somewhere one of these days

i still have one of these bad boys in my computer parts box

The size of standard desktops in 2032 with the 8000 series.

Spent the day actually fine tuning my 6900XT OC.

Found that just blindly increasing the Power limit just means the card overheats and does nothing with the power.

Sweet spot for me turned out to be increase power limit by 5% and undervolting by 100mv.

Higher power limit gets me an extra 0.5/fps and 5-10c hotter card.

Which 6900XT do you have?

My XFX Black seems to relish a bit more power and hasn't looked like overheating. Will shut down with instability if I push it too hard. Can't recall what settings I have at the moment.

I've got the Powercolor 6900XT.

Current settings are

Max Freq: 2600mhz
Voltage: 1080mv
VRAM: Fast Timing @2150
Power limit: +5%

What are your fan settings?

This seems to be stable enough and I can game at around 66-71C.

EDIT: If I push the voltage to 1150 and keep the power limit the same at +5% I lose about 2.5fps and have a 2c hotter card

4090 4k bench results are crazy

 

[gaskin]

Watching Jayz video now and will watch HUB's game benchmarks after it. I thought they were exaggerating when talking up the performance jump from the 30 series but the difference between the 4090 and 3090 is ****ing massive to put it bluntly. These are only the FE cards as well since the AIB reviews are still under embargo.


Edit: I'm watching HUB's game benchmarks and it seems to be at 1440p the gains aren't as drastic when there is CPU bottlenecking and/or games like AC: Valhalla that were much better with AMD cards than Nvidia. It is really at 4k where the 4090 comes into its own.

Probably not long until TDP is measured in Dyson spheres.

Got an ad email from cablemod advertising their 4090 compatible cables. As usual I cringed at the "support up to 600w" description but I thought I'd do some working to get an idea of the headroom they're looking to cover. Power is voltage*current. We know the power and the voltage so to get the current you can swap the formula around to 600w/12v to get 50amps. They're advertising 16AWG wire which is a stupid American wire standard. In metric 16AWG is between the 1.25mm and 1.32mm wire sizes. Usually when I'm determining cable sizes to weld to the wire I have a chart that tells me the full load current rating of the cable sizes and I match the sq/mm of the cable to the wire. 16AWG is 1.308sq/mm and good for about 12amps. These cablemod cables are 12 wires of 16AWG and since current splits over parallel paths you're looking at a potential maximum full load carrying capacity of around 144amps which is waaaaayyy overkill. Not to mention this would also exceed the full capacity of the 12v rail of a 1200w PSU. I think these cards are looking at a 40-50amp draw as per the "600w" reference.

So long story short, rating wires/conductors to a power rating is useless and the whole thing is just really just marketing.

I imagine you sitting in your lounge room with a Mig welder, trying to attach power cables to a 4090 in a microATX case.

If anyone is after quality local custom cables I highly recommend Yokai Customs from Melbourne.
