GTS450

Looks like overclocked these babies are pulling in 13-14K PPD, for around £100 and only 100W they might be worth switching your older 8800/9800/GTS250 type cards to. Run at 55°C under load as well which can't be bad.

No waterblocks so not for my main rigs, but looking good for any aircooled guys

thats almost the same as a gtx460!! What clock speeds are we talking about?

verbal · 13 Oct 2010 at 13:44

I'm considering one. From what I've read it'd be a fairly hefty OC to get 14k ppd! Looks like I could easily do more ppd than my two 8800GSs combined whilst using less electricity though.

Damn it I've just bought 460s!! I'd better clock them a little more so I feel like I'm getting my moneys worth!

This is a great upgrade option.

Grimgoth · 13 Oct 2010 at 14:06

those must be some hefty overclocks, because the wiki lists the stock GFlops of a 450 as 601.34, whereas the 250 is 705.24?

But then I guess the shader of a stock 250 is at 1836 MHz, whereas the stock 450 is at 1566....

Yeah but the 450 can run GPU3 properly, also the 450 has 192 stream processors vs 128 on the 250.

Are the core and shadders locked as with the other 4xx cards?
very tempting - and info on which cards are the best clockers?

Frozennova · 13 Oct 2010 at 17:30

shaders are locked on all 4 series cards, Asus MSI and gigabyte seem to be the best clockers of the 460s so I'd say the same applies to the 450

looks like asus, with evga & msi in close second (if you inc memory oc's)

How does GFLOPS even relate to Folding? I tend to use it as a guide but I don't know if it's applicable.

Very tempting!
Do the GPU3 wu's give more ppd?
<heat <noise <power than my 260 & more ppd

So if a 768MB 460 is 20% in price do you get +20%ppd?
I suspose the leccy is a factor too.
I wonder if OcUK with increase the range they stock.

Rizo-UK · 13 Oct 2010 at 22:49

Just ordered one of these puppies

OC'd Edition with a 880mhz core

let the folding commence

Biffa · 14 Oct 2010 at 00:24

Make sure you run it with -advmethods and if folding on cpu as well assign it a core to the gpu

AFAIK GPU3 wu on a gtx260 give less ppd than a gpu2 wu

GTX460 cards will not run GPU2 only GPU3

My gtx460s (MSi Cyclone 768MB) run cooler quieter and consume less power than my gtx260s

GTX260 576/1500/999 aprox 7200 - 8500 PPD
GTX460 850/170/1800 aprox 10300 - 14300 PPD

However GPU3 core hogs interrupts and adversely affect CPU folding - my i7 920 will only just complete a bigadv unit and if I remember correctly loses about 6000 PPD

with 2 GPU3 wus running

Is your i7 920 OC'd? If so, to what?

Biffa · 14 Oct 2010 at 08:40

I agree, you need to assign one thread on the cpu for one Fermi, with two that thread has to be a real core not a HT core, and with 4 you need two real cores.

yes, 3.8GHz

Thanks for the info Didgemaster, most helpful.
Not cpu folding at present but with the new Ubuntu out I might try SMP via a virtual machine once again.

Any particular reason for using a VM?

You might find that it will impact on GPU3 depending on priorities. The new (ish) smp2,A3 core windows client does away with the need to run VMs to get points.

Only because that's how I run the Linux SMP in the past but if the Windows version is better, more stable & gives similar points [Linux used to have a points advantage] no reason not to try that.

Upped my shader clock by 100MHz & that has shaved 2-4 seconds off a frame
