That link really interesting and encouraging for CUDA crunching on PCI machines.

Per the Zotac website, there is no fan on the PCI version. That could be a problem for crunching.

My 8500 GT had no factory fan & got rather warm while crunching. So I attached a small, 50 or 60mm, fan to it. It doesn't make any more noise and stays much cooler.

Yep, any fan is better than none at all. A PCI slot exhaust fan might be enough, as long as air is moving over the heatsink.

Does your 8500GT use just a single slot?

Well... it did. The fan sticks out far enough that it would prevent me from using the adjacent slot. This is what the card looks like, except I've got the 256MB version. So it probably has fewer memory chips on it.

Looking at the GeForce GT520 PCI card I see it has 48 shaders, where as the GeForce GT430 PCI (also ZOTAC) here has 96 shaders and should, technically, crunch faster.

Some info about GeForce:

GT430 = 268.8 GFlops / 49 Watts (5.49 GFlops/Watt) - $
GT520 = 155.5 GFlops / 29 Watts (5.36 GFlops/Watt) - $
GTX560 = 1088.6 GFlops / 150 Watts (7.26 GFlops/Watt) - $$
GTX590 = 2488.3 GFlops / 365 Watts (6.82 GFlops/Watt) - $$$$

GTX560 is a good choice for those with a good power supply, and GT430 / GT520 for those with an average PC.

Well if the GT 520 PCI has only got 48 cores i would not touch it with an AMR slot.
My GT 430 PCI @ 96 cores is doing quite nicely,
it is the only thing i am using on seti atm, and rac is still going up if i can get regular work.

<<<<<<<<<< see RAC for details :¬)

I got myself a Zotac PCI GT430 a couple of days ago, i've put it in my E8500 at the moment and set up a 2nd Boinc Installation for just that GPU:

Computer 6199212

Since it's a Fanless GPU, i've set up a Fan pointing at it, temps are ~50°C.

Interesting clive G1FYE's card seems to run normal ~0.42 AR tasks in the 3000-3500s time frame & Claggy's is running 4000-4500s for similar AR tasks.

I wonder if this comes down to how the boards/chipsets are designed, the version of drivers, or the platform.

Clive's clockrates are higher, and i'm running an Alpha diagnostics app that is probably slower than x38g:

Did you get the GeForce GT430 in the UK?

If so, can you recommend an outlet?

The ones I have are German, and I have yet to approach them, so how to pay (kept away from credit cards) may be an issue for me.

I got it from MicroDirect, or you can search the Part Number (ZT-40605-10L) on Google, then click Shopping for others, i hadn't heard of any of the other's so went for MicroDirect,
and payed with Paypal.

I`ve bin spy`d on :¬)

Clive's clockrates are higher

GPU 856mhz
MEM 810mhz
SC 1713mhz
TEMP 55c < 60c
NV DRV 266.58
BM 6.12.33
WIN 7 home 32bit

There is a little bit more left on the memory overclock but i know i am running it close on the GPU / SC, it crashes at 870mhz.
It is a fun little card and easy to set up and use on SETI :¬)

Thanks arkyn and Claggy.

Unfortunately the Microdirect.co.uk link was for a PCI-E bus GT430. I am looking for the PCI (not Express) version, which I can see here.

As you can see from the menu on the LHS this is a PCI (not express) only card and the same as the PCI-E version.

I would need to ring MicroDirect to enquire if they stock the PCI version.

That is the PCI version, check part number, the Specifications on the right is Wrong.

Check Manufacturer's page for PCI GT430, check part Number there: http://www.zotacusa.com/geforce-gt-430-zt-40605-10l.html

Claggy

I also checked the connection and that is definitely the PCI version.

Great reassurance, and thanks for the recheck.

Good to know I can source in the UK when I need to play.

The fan is a must on the ZOTAC GT 430. I shut mine down at 80C and installed one. Happy at 50C now and could probably overclock it some. Completes a work unit in about 85 minutes at stock clock on an old Dell 2400 . Got mine from Newegg.
