KFA2 GeForce RTX 4090 SG 1-Click OC 24GB PCB design

[cinderman]

Hi guys I’m getting cross signals here, on this forum they state the kfa2 has 18+3 power phase, however I just saw this picture with 14+3 from Alphacool which makes me think this is a worse design than the palit card Even zotac.

https://www.alphacool.com/download/compatibility%20list%20Nvidia.pdf

I just ordered this from Overclocked and it hasn’t been shipped yet, so I’m a bit worried whether I should cancel this order today.

edit : on the official website it said 22 power phase. The picture given by alpha cool may be referring to the pcb design itself as I went through and clicked on several ‘Nvidia reference board’ on the spreadsheet and it had the same image…

 

[cinderman]

Power phase on the 4090 does not make a huge difference.

For example Palit GameRock is like the worse and MSI Suprim is the best yet @LtMatt has a Gamerock on this forum pretty much out performing all other 4090s so I’d still not be overly worried.

yeah I was initially scared off by https://youtu.be/9I7U4kdc0V4. When he talked about pcb designs of the nvidia 4090s. But had my opinions changed a bit after checking framechasers etc.

As I said though (in the edit at least), it is a 22 phase card, Alphacool was using the pcb reference design picture which many of the INNO3D,PNY & Palit subsidiaries like Galax/kfa2 , Gainward all use!

it’s actually a very good card, but the lacking warranty is the only bad side for me.

 

[cinderman]

Not familiar with this card but yeah the GameRock having a supposedly bad PCB meant very little in real world terms if you know how to tune a graphics card.

Yeah I’m planning to underclock it with MSi after burner.

Did you end up getting this card and if so how is it?

I almost bought one myself yesterday but the price jumped up £100 so I decided to leave it.

Looks to have been a cracking deal at £1599 IMO. Is it going back to the original price anytime soon @Gibbo ?

Yes I did, it’s a visually stunning card. The pictures doesn’t do it justice.

i haven’t started running it yet as I had some issues getting it in my case as it had stated it was 336mm and 357mm with ARGB stand on their website. In fact it’s 357mm so I had to take My computer apart (corsair 5000x) to make it work well.

The picture is a bit janky, I’m going to run it for awhile in its current form to make sure there’s nothing wrong with it. I’ve also ordered Corsair’s white sleeved Premium 600W 12VHPWR PSU cable.

I’ll update you when it’s done.

I personally think this card is definitely worth the money and out performs most of the other manufacturers (based on reviews and reading up about the Galax/kfa2 brand)

it’s a shame you missed out when it was only £1599

 

[cinderman]

i would suggest not to use the app or software that comes with it windows does not like it. when i used it the memory got stuck and would not go back to default until i completely nuked my os :/
does anyone know if the galax bios can be flashed to these kfa2 cards ?

I was thinking of just using the nvidia drivers and msi afterburner tbh, with Aida64 to monitor everything.

 

[cinderman]

You think £1,600 is a good deal for a graphics card?

It’s a flagship product! Why do people buy a Lamborghini if a ford fiesta will do?

Anyways comparatively company’s and especially scalpers are selling the ASUS Strix models for over £2000.

I was initially going to get a 4070ti but the limited memory and bandwidth ruled it out for me, then I set my eyes on a 4080 and the AIBs were selling it too close to the MSRP 4090 price And 30% slower at that. Prices will go down eventually, so what do I wait for 5 months without a computer for that ?

 

[cinderman]

That's exactly what I'm using to monitor it all now.
Trying to configure my AIO for the osd and custom overlay now pita
I don't get me started on configuring argb lighting took me longer to figure that out than build my pc in first place.

Not to mention all the tinkering to get Aida64 just right. It’s all fun and games, I’ll take my time

 

[cinderman]

Because you can buy a seriously cool car like an Alfa Romeo Giulia Quadrifoglio for a fraction of the price and gives nearly all of the performance and has all the practicality that comes with a saloon.

In that case no one would drive a Lamborghini as everyone is in the same financial situation!!! Everyone will move from their mansions to a 3 bedroom house as it’s more practical and you get the same results. People would all move from luxury goods as normal goods does the same thing….

Anyways I’m going on, it’s up to the individual to decide what’s good and what’s not. As long as you’re able to enjoy yourself without harming anyone else! No one should judge or care!

 

[cinderman]

Curious to know how you fellas get on with it, looks pretty decent and perhaps a worthy competitor to the GameRock OC.

I ended up going with the Gigabyte AORUS XTREME WATERFORCE myself.

what persuaded you to pay 600 more to get that card btw? Wouldn’t an ASUS strix be better At that price point?

Gamerock is a Palit card, KFA2/Galax is the high end subsidiary of Palit, as is Gainward and a few others.
Galix/KFA2 make the the ridiculously over specced Hall of Fame cards which beat even the best EVGA series cards.

Finally installed the last 3 fans so im off to play minesweeper

I’m not sure if your system is capable of playing that yet though. it’s an easy fix though, just get more RGB

 

[cinderman]

The extra fan you get that clips on the back is a bit tacky.
I have not installed it to try the temps but I have adequate airflow so won't bother.
Cinderman what have you done with the monstrosity of the glow stick?

Yeah it’s really tacky, if I really want to use one I’ll place my spare QL120 there. But from what I’ve seen there’s virtually no gain.

I‘m still waiting for some things to arrive (white ATX+GPU sleeved cables, USB headers) until I can test the card & close my system. I’m just going to test everything works with the GPU and it’s accessories.

You can see the the glow stick behind the janky hose leading to the CPU. I haven’t decided yet if I’m going to get rid of it & use a riser on the setup, I’ll use either the Corsair 4.0 or LINKUP if I do do it, but for at least for my return window I’ll make sure everything is working 100% with no reasons to blame faults on anything else in my system.

 

[cinderman]

I know, but the GameRock is renowned round these parts for being god tier, mainly used by high skill level operators.

Sorry did an edit but you replied before I did it.

I asked what persuaded you to pay 600 more to get the gigabyte water force card? Wouldn’t an ASUS strix be better at that price point?

 

[cinderman]

no matter where i place the support stick it would somehow drop slip or move and the last thing i wanted is a cracked pcb through the weight of it.
i decided to see if vertically mounting would help with not only allowing me to put my side panel on but also to easily inspect the 600w cable but to alleviate the weight on the pci e slot.

Maybe you got a faulty one, mines fully adjustable and holds fine.

was the base of your case metal btw ? It’s also magnetic!. Also there’s plenty of 3rd party ones if you weren’t happy with it.

[cinderman]

I don’t think you had a choice but to vertically mount it. If the fans weren’t there, it would have worked and the fans themselves are plastic so no way to get a strong grip.

Anyways I have the weekend now, so I can finally get to work on my own rig, I haven’t even switch it on yet !
