When I run the GTS450 solo, it gets 9200ppd in either slot. When paired with a GTX460, it drops to 7900 regardless of how much I overclock. Gotta be a PCI conflict somewhere. When I ran the GTS450 with 3x GTX460's, all hell broke loose in Afterburner with fans and clocks all over the place. In the infamous words of Dexter Holland of "The Offspring"...."Gotta keep em' separated"

Hmmm, when I get a chance I will see if there is any difference running the GTS 450 by itself, the 470 by itself, both without WCG running, and each solo without WCG running and post back the results. Ill try to get it done this week or weekend.

I have a Palit GTS450 that I acquired through a trade. I have it on my kiddo's rig and here is a sample screenshot:

[TeXBill]

Here is the 2 Gigabyte 450's running together in the 655K rig. Once I put them together it dropped in point's by about 1.5K PPD each, plus my OC was not stable any more. I plan on sepearating them again and OC them back to the 1000/2000/2000 I had them before I paired them up.

[TeXBill]

Here is the new bigadv rig. I put 2/460's in it and found that was a mistake, lost almost another 1.5K PPD each with them also. I've found out pairing same cards together is not the right choice. I will be separating the pairs and mixing them up and see what results I get. I know my OC's will be stable again. I'm not sure if the PPD will go back up.

What the processor thats doing the bigadv? And how are 6900 WUs compared to 2684s?

After much waiting, and many hiccups, I'm finally folding at my max capacity (well, almost).

My bigadv is now folding with a 470. My main rig is folding SMP, and on a 470 and a 8800. I still have one 8800 I need to figure out where to put. I'll call Asus Tech Support tomorrow and figure out why I get no display with two GPUs in my P8P67 board.

On, normal days, I should be netting around 30k points, and days I drop bigadvs, I'll be a little over 90k. Add another 5k to that once my second 8800 finds a home.

Very impressive, I'm glad to have you

[thebluebumblebee]

Well, I'm back, empty handed. I swear that random.org does not like me.

May I inquire what you were trying to accomplish?

[xbonez]

So, i have an 8800GT I'm trying to OC. Upto clocks of 700Mhz, it folds fine. Any more, and it fails WU. Temps are not the problem, as I'm in early 70s. MSI Afterburner doesn't allow me to push more voltage to the card (Voltage control unlocked in settings). Is there any way to control the voltage to an EVGA 8800GT, or is it not possible?

I never could find a way to do so on my 8800GT (reference)

[xbonez]

Oh, also, on my 8800GT, should I be check the GPU3 client option?

Don't try to push the core so hard. It's the shaders that count. If you want to get into volt modding, get in touch with P_O_S_PC. My 8800GTS runs at 670/1890. 100% stable, and that's what counts for me.

Ah, yes. I've spent so much time with Fermi's I forget that in the 8800 the core and shaders aren't linked. I'll reduce core and increase shaders.

Also, my 2600K BSODed after about 8 hours of folding @ 4.8Ghz. I decreased it to 4.7, and its been folding good for over 24hrs now.

I also started folding on my 470 on that rig. So, the drop in 100Mhz combined with the overhead of a GPU client increased my TPF on a 2684 from 35:30 to 36:56. I'm not too bothered as I'm getting over 40K from that rig right now.

Also, for a bit this past month I was a little financially tight, but things have worked themselves out. So, it seems I might be able to put my tax returns toward another bigadv rig.

Also, I no longer feel the need to sell my 470 for cash. However, I'm thinking that I might still sell it and pick up two 460s instead. That'll be a good 6-8k PPD more and shouldn't be more than 20-40 bucks cash on my end.

Nah, on all pre-Fermi cards, GPU2 gives better PPD

the cpu is a 875K OC to 4.0GHZ, the WU's I'm not sure of it's still in the early stages and has only finished a couple of them. I will try and look into it and give you more advice about the WU's. I'm still laid up and can not move around like I want to so the rigs have not been attended to like they should be. Once I'm back on my feet I can give you more insight into the WU's.

Great price on a 480 - $240

I just read this on the Folding forums:

2) The minimum amount of RAM is 0.50 GB/Core which turns out to be 4 GB. The recommended is 0.75 GB/Core which equates to 6 GB. The more-than-enough is 1 GB/Core which results in 8 GB. Note that 32-bit OS can't use RAM sizes above 4 GB. (This is the Official requirement for Linux and OSX. There isn't any Official word for Windows yet but RAM Usage for F@H Client is generally <2 GB)

My current bigadv rig is using only 4GB RAM, while I have another 2Gb stick lying around. Should I throw it in too? Will the loss of dual channel make any diff to my PPD?

Assuming you have at least a GB free during normal usage, I'd just leave it as is

[TeXBill]

All of my bigadv rigs have at least 4GB if not more and I'm using Win7 64bit.
I'm not sure that losing dual channel will affect the rigs folding on bigadv, but that would be a question for somebody that knows more than I do about that subject.
That is the first I have read that more than 1GB/core is more-than-enough for folding. I've always went by the rule .50GB/core was the best and more does not matter. Guess I might have to do some testing and see if this true.

I'm limiting 1 bigadv rig to 2GB and will see what happens. I've put 2/1GB in dual channel mode and will test it for a couple of days and see if PPD increase or decrease on that rig.

Nice find let's put it to the test now and see how true it is.

Thanks for the read.

[TeXBill]

WOW Buck kakaostats.com has me passing you in 49,886 days, I just don't see that happening. I don't see myself advancing any more for the next several years if any then. I have to many good PPD people in front of me..

That's certainly quite a while for him to come up with something new

Edit: Exactly what I thought.

Anyone know what PPD the new Sandy Bridge chips get? I mean the 2600k if anyone has one.
