X1900 to 5750 on a 4800 X2 (939)

[Pederv]

Turned my 4800 X2 (939) over to my wife. It's configuration is:
4800 X2 (939)
Epox 9NPA+SLI
4GB Mushkin 3200@2700
X1900 AIW

The benchmarks I ran scored:
3DMark2001SE - 25458
3DMark2003 - 14525
3DMark2005 - 9070
3DMark2006 - 4508


I decided to upgrade the X1900 because it wasn't up to par when playing NFS:Shift, so she got a 5750. The benchmarks I ran on it scored:
3DMark2001SE - 28676
3DMark2003 - 32897
3DMark2005 - 12823
3DMark2006 - 8963

I was curious so I pulled two sticks of RAM, so that it could run at full speed, and the benchmarks scored:
3DMark2001SE - 29788
3DMark2003 - 33050
3DMark2005 - 13088
3DMark2006 - 9069

I just setup a 620 with a 5750 over here:

So it looks like my old system is holding the 5750 back. So much so that my nephews system:
5000 X2 (2.6GHz)
Gigabyte 770 AM2+
4GB DDR2 1066@800
ATI 3850

His benchmark scores and my wifes, are pretty close:
3DMark2001SE - 30786
3DMark2003 - 30353
3DMark2005 - 13679
3DMark2006 - 8678


I did have a problem, when I was installing the 5750 in the 9NPA. The 5750 doesn't work in the primary PCI-E slot but it works in the secondary. The information that I've seen so far says that either slot is capable of 16X. If that's not true then that might explain the big difference between the 620/5750 scores and the scores I got here, these benchmarks are pretty much single threaded. If it is true then this system is just about maxed out, a blueray player is all it needs (and a new chipset fan).

3d mark 06 with 5750 and system in signiture = 15,000+
But that benchmark is just too old and depends on your cpu too much.

If you have windows Vista or 7, try 3d Vantage.
I scored like 10,000+ with my 5750 on that.

Don't worry about the PCI-E speed, even at 4x won't bottleneck your card, not even an HD 5870 significantly.

You're getting killed by the CPU, pure and simple.

I did 7800GT -> HD4850 @ 1680x1050 (almost similar cards to yours) with an X2 4200+ and got better performance in some cases (Bioshock) but no real difference in others (Fallout 3).

Then I did X2 4200+ -> E5200 @ 3.4GHz. Really unlocked the new card and let me run pretty much anything that I wanted with reasonable settings at 1920x1200 (I upgraded the monitor at the same time as I upgraded CPU). Obviously some things (e.g. Crysis) weren't so happy, but everything else I can think of was.


No idea about synthetics, since I didn't bother with them. Real world impact is much more important.

After I posted this thread I took a look at Happy Medium's thread.

I checked the Catalyst Control Center and the card is running at X1. I can try reseating it in the primary PCI-E slot a couple more times but I think the card is where it's going to stay.

Might need to do some fiddling in the BIOS to make both slots run at 8x or so.
It might be that one is at 16 and the other 1, and in the BIOS you can switch them to 8/8 (or there is a switcher card on the mobo that you need to fiddle with).

Thanks for the idea Lonyo, I put the motherboard in SLI mode and it brought the speed of the secondary PCI-E up to 8X (the 5750 still won't work in the primary). The benchmark scores look like they'll come up a bit but not as high as the 620/5750 system that I put together.

It's just something with the 5750 because my 4890 works in the Primary PCI-E slot.

 

[Pederv]

After putting my 9NPA into SLI mode, so that the secondary slot is working in 8X instead of 1X, the system returned benchmark scores of:
3DMark2001SE - 30612
3DMark2003 - 37598
3DMark2005 - 13110
3DMark2006 - 9254

A modest increase that may never get utilized, but better to be prepared.

3DMark 06, 05, etc are just not that great of metrics to compare one system to another. The score is meaningless. The actual framerates you get in the individual tests of 3DM06, for example, matters more.
