PPD for a Q6600?

MikeTimbers · 13 Jan 2008 at 18:33

What are you guys getting out of a Q6600 and at what speeds? With what client?

I'm trying to justify an upgrade but need to know how many extra PPD I could get.

A.N.Other · 13 Jan 2008 at 18:36

With my Q6600 at stock, I get around 2600ppd with two winSMP clients.

Pretty decent

I believe Jaric is the top guy for one quad core on between 4.5 and 5k PPD. That's with 4 linux SMP clients though (2 VMWare images with 2 linux SMP clients).

A point to note about the SMP clients, the Linux ones are a lot better processing wise, so even a VMWare image runs faster thana Windows SMP client.

3k ppd with 3.15ghz Q6600 with 2 windows smp clients

Berserker · 13 Jan 2008 at 18:55

3k PPD at stock with 4x Linux SMP clients on 2x VMWare.

Yeggstry · 13 Jan 2008 at 19:00

Oh I believe that jaric is on 3.75GHz

Q6600 at 3.5ghz and four linuxSMP clients spread across two Ubuntu Server VM's is currently getting me -

jesus!

I know nothing and i mean nothing about linux vmware etc etc - but tempted to start if i can increase output by 50%

Q6600 @ 3.7
4 x LinuxSMP in 2 Virtual Machines

*stab stab stab!!!

Very nice!

Wouldn't you get slightly more with two server images instead of one server and one desktop?

Berserker · 13 Jan 2008 at 21:30

Think I may have to try and O/C my Q6600 a little. I've had 'er up to 2.7 before but that was when new. It's a case of not being sure about how best to ensure it's stable and not wanting to lose too much time over it.

I just upped the fsb to 333 on mine running stable crunching two smp clients for 4 days now

Didnt even have to alter any voltage

I also get an average of 3000 ppd.

Does that hold true even with a dual-core? Any how-to's out there?

Yeggstry · 13 Jan 2008 at 22:42

I don't know, I only saw someone talking about the quad in another thread.

I keep meaning to do a fresh server install and then clone it, as I'm still running 7.04, but never seem to get round to it. I've found the difference between server and desktop editions to be fairly small, as you can see, but as the virtual machines are only used to fold I might as well use the server version for maximum crunching.

For dual core machines just use 1 virtual machine running 2 SMP clients. On my E6300 @ 3.3 I used to get around 2000ppd.

For a guide on the setting up the SMP client have a read through SiruisB excellent guide here. It covers WinSMP and LinuxSMP running natively or in virtual machines.

On a side note - ppd can vary considerably depending on the work units being crunched. 4 "bad" WUs on my quad can drop my ppd down to around 3600.

Hmm, I get that under Windows-SMP with a single SMP client on an E6600 @3.3
so maybe there isn't much to be gained. It used to be less until I started using FAH SMP Affinity Changer which helps keep the four clients optimized across the cores. Added a good 5-10%.

gurusan · 13 Jan 2008 at 23:51

hmm I get about 4400-4500 PPD using 2 instances of windows SMP clients with my Q6600 @ 3.56ghz under Vista 64

theheyes · 14 Jan 2008 at 00:28

Pretty impressive PPD's out of 1x Q6600 there guys.

I get the same from one WinSMP and one Linux/VMWare SMP. It's a bit simpler....
