Preview for the cheaper Yorktown procs.

[muddocktor]

Hey guys, I really can't believe how well this QX9650 is at Seti crunching. For all of you that are waiting for the cheaper Yorkies to be released, this is what I have been seeing since I replaced my Q6600 (and old mobo) in my main rig with the QX9650. Basically the biggest differences between the QX and the upcoming Yorktowns is the fact that the new Yorkies will be clocked lower and won't have the totally unlocked multiplier. My QX is at 3700 MHz, for reference. Here's a pic of what I've seen as far as RAC increase since I upgraded:

The part of the graph to the left side was with my older Q6600 was running at around 3050 MHz and it's very easy to spot the upgrade in the graph. If you can overclock the upcoming Q9450 to around 3700, it should do basically the same as this since it has the same amount of L2 cache as the QX9650.

I was wondering about this rig when you posted it had a 4700 RAC in the power thread. That is incredible! I noticed on BOINCstats that this shows up as 2(4) instead of 1(4) like a Q6600 on the CPU (cores) column. I wonder why that is? Either way, :drool::drool::drool:

[donuts]

I can't wait.:drool:

You got a nice RAC :D

[muddocktor]

Yeah, this QX kicks ass on Seti. :D

And I'm not really pushing it hard either. Only running at 3700 to get this RAC. One of these days I will feel motivated enough to really fine tune my overclock on this machine and I imagine I should pick up some more RAC out of it.

[QuietIce]

Nice! What's that plateau in the middle - stock speed ...? :)

[muddocktor]

That was right after I had installed the new mobo and proc and was working up the overclock on it. And the dip happened while I was at work; for some strange reason the client didn't want to transmit the wu results back to Seti. I had to have my daughter reboot the machine to get it to act right. It was like the BOINC client got confused or something. I haven't seen the client do that since then, but I also upgraded to a current client too as the one that was running back then was kind of old.

4GHz should be cake on that chip.

[muddocktor]

Yeah, it should be but not right now with the case I have it in. I'm running the system in a Silverstone TJ-06 case and with the placement of the cpu socket on the board I can't orient my U-120-X to where it points front to back (upside down case orientation). I presently had to orient it to where the fan blows towards the bottom of the case, making for not so good cooling. When I finish paying off this QX I will be in the market for a good replacement case with better layout and maybe something I can watercool with too. I already have an Iwaki pump, dual 120mm heatcore and the tubing; would just need to get me a good waterblock to go with it such as a D-Tek Fuzion.

[Careface]

You wont be disappointed with the Fuzion.. thats a really high quality block there.. ofc you know this, but hey :D.. Im still partial to the ApogeeGT myself for some reason.

Really nice RAC btw mate :thup: Im jealous :(

A Fuzion (and heater core) is what I'm running on my Q6600. 3.4 GHz @ 1.52v under SETI/FaH load and the cores are running 40-45°C. I made a "custom" jet/nozzle using a crimped piece of 3/8" copper tubing, which fit right down through the barb hole and sat flush with the bottom of the middle plate! :D Considering temps vs vCore it seems to be working well but I would like to completely seal the middle hole and see what that does. I'm sure some of the water that should be going out to the corners takes a U-turn there in the middle. But maybe that's not a bad thing since most of the heat is there as well? :shrug:


Is your X38-DQ6 board the one you have mounted upside-down? What kind of chipset temps do have ...?

[Rickdstik]

Well I was going to hold out on the second quad ... but Fry's has the q6600 on sale for $189 ... no way I can pass it up any more. Second quad should be in today.

Yes, the DQ6 is the one I mounted upside down. I didn't load the Gigabyte monitoring program (Easy Tune) on my machine as I had problems with it on my DS3L system at one time, so I monitor with Speedfan 4.34 beta 44, which seems to read the board ok. It is showing two valid temps on the IT8718F sensor and one is at 33 C and the other is at 34 C It also shows a thrid IT8718F reading of -2 C, which is obviously a spurrious reading and also shows a LM75 chip reading of 2 C, which is also some kind of wrong reading too. The last released final version of Speedfan (4.33) wouldn't read hardly anything on this DQ6, even core temps. But it looks like Gigabyte's heatpipe cooling solutions for the nb and sb work well even upside down.

And Rickdstik, that is a hell of a good deal on the Q6600's that Fry's is running right now. I don't blame you a bit for going for it.

[Rickdstik]

Great thing is, since I got the other one two weeks ago, they refunded the price difference I paid on the other, so I ended up getting them both for 189

[muddocktor]

Man, that really worked out good for you then! :thup:

[Rickdstik]

Just a note, MicroCenter's website also has the q6600 listed at $199. Ive got some work to do on the x-qpack. I want to get the same cooler (Asus Silent Knight II) on the new q6600 but there's currently not enough clearance. Oh well, my handy dremel comes out today and part of the support brace that holds the hard drive cage (which has been removed already) goes away. Six heat pipe cooling and blowing right into the 120mm exhaust fan should take care of my slightly high CPU temps (currently sitting at 66C at 3GHz/1.3v)
