ATI X1900XTX 512MB

Danger Phoenix · 13 Aug 2007 at 21:20

I was just wondering if the HIS X1900XTX 512MB can be flashed to the BIOS of the X1950XTX to make it faster?

No as they have different memory, tho its easy to clock the 1900's faster than the x1950.

Hmm... because I made a thread in the Wanted Forum, and I got this reply from a seller:

card is A1 condition. bios has been flashed to to that of an x1950xtx. zero issues with that. comes in original box with all cd's, flatout game.

Well its BS cos it just wouldn't work.

Once overclocked the X1900XTX is a better card.

I asked him about it and this is what he said:

well this one has. it has the toxic bios settings.

Well there was a toxic X1900XTX, I nearly got one instead of the IceQ one.

But i really doubt the G-DDR4 X1950XTX BIOS works on a X1900XTX, maybe it does but im 99% sure the BIOS wouldn't work, or wouldn't work to its full potential, maybe it does work but uses G-DDR4 timings but then only rare good cards reach 1000mhz mem.

So I call BS.

Its probably been flashed with the Saphire x1900xtx toxic bios, could even be my old his Card, sold mine with a toxic bios

CB666 · 14 Aug 2007 at 06:09

Right my mistake guys, i knew the guy had done something to the x1900xtx to make it better, just completely forgot about the toxix cards that came out. so I assumed that it been flashed to that of a x1950xtx.

sorry my mistake.

Danger Phoenix · 14 Aug 2007 at 07:23

Come to think of it, are you sure it is not a X1900XT flashed to X1900XTX?

Could you give me exact model/product codes?

CB666 · 14 Aug 2007 at 08:54

defo xtx. will send ya pic when i get home tonight if you wish.

Really... and what about the memory, not just the core. x1950xt's (GDDR3) can go to 2000 (1000mhz) with no voltage changes to the memory. My core went to 702 with only a miniscule voltage increase and stock cooling. Please explain how the x1900 is better.

Sincerly,

Errr, X1950XT is G-DDR4, thats why it can hit 1000mhz mem.

X1900s are G-DDR3, and G-DDR 3 @ 825-850mhz > 1.1ghz G-DDR4.

Tighter timings ***.

Cores are the same, so its all down to mem.

No G-DDR4 car has passed 1.15ghz mem. While G-DDR3 cards have regularly passed 850, and some passed 900mhz.

Thats why the single X19x0 records are held by X1900s.

Shocky-FM · 14 Aug 2007 at 13:32

Can't you just flash the card with the max stable overclock ? Doesnt really matter if it says x1900 or x1950 now does it.

X1950xt's are normally GDDR3 (hence me writing it in my post *crazy*

)

X1950XTX's are GDDR4 (hence the extra expense).

hah! Never noticed that.

I wanna see some proof over 1000mhz tho, cos they aint gonna be using 1ns chips on cards like them, I bet they are 1.3 or even 1.4ns so 1600mhz is the most your gonna get....

Scougar · 14 Aug 2007 at 16:09

My sapphire x1950xt (that I sold last week), did 702/2048 with very little effort. 1.475 on the core instead of 1.45, and the *very slight* of memory voltage increases as I haven't really played with memory volts before so was

It came with the memory set at 900mhz (1800ddr), but is 1.1ns memory, so should really be set at 1000(2000ddr).

Instead of increasing freq you can also drop the timings so allow faster speeds as the memory works with the old 1900xtx timings

I didn't try pushing anything with voltage as I wasn't sure if I was going to keep it or not.

This is why I get confused as to why people keep saying the x1900xtx is better for clocking than the x1950xt. with the 50xt you can push the memory speed that much faster and still get the core high.

the x1950xt is ddr4, diffrent memory from x1900xtx

um.. no. 1950xtx is gddr4

x1950xt is gddr3

Err, cos its only 256mb? LOL

SO yea, X1900XTX is a better card

Once overclocked:
X1900XTX> X1900XT* > X1950XTX > X1950XT > X1950 PRO

* depending on if its a good clocker.

At stock:
X1950XTX, X1900XTX, X1900XT/X1950XT > X1950 Pro

Well guys, I paid £95 for the HIS X1900XTX 512MB

Hopefully I can sell my old X800GT with Arctic Cooling for £25, and the whole transaction will cost me around £73 (counting postage costs)

Excellent choice.

Out of all the cards thats the one to go for with the IceQ cooler I assume?
