CrayZ1 is the computer I personally use at work for CAD, Excel, email, etc.

Antec 300 case w/430w powersupply
MSI 890GXM-G65 AM3 mini-ATX motherboard
4 GB DDR3-1333 ram
AMD Phenom II X6 1090T 3.2ghz CPU stock fan
MSI GTX460 Twin Frozr II
Window XP Home 32-bit

Settings:

Base speed changed from 200 -> 220, 16x multiplier = 3.6 ghz 50°C.
GTX460 set to 825 mhz for GPU, and memory speed 1800mhz. 40°C.

GPU3 client installed normal, with -advmethods option flag. ~13500 PPD

Console SMP2 client with "big" and -smp flags entered during configuration. PPD for 6701/6702 jobs is ~6,000, with a 11:30 TPF.
PPD for 6065 jobs is ~10,000 with a 4:30 TPF.

It should be past the "10 units" by tomorrow, and I'll let it run a week then make further adjustments. Note, it will run Starcraft 2 on ultra at 1920x1200. Not that I would play games or anything ...

That was clocked at 4.0ghz, and got 1/2 way through the job, then "Core Unstable, quit job". :(

It didn't blue screen or hang. It just dropped the job and restarted another one.

Most aftermarket motherboards for desktop computers sold in the last 5 years support some form of overclocking.

AMD actually acknowledges it, and helps motherboard mfr's and buyers with overclock info.

A good read for AMD is

http://game.amd.com/us-en/content/pdf/AMD_Dragon_AM3_AM2_Performance_Tuning_Guide.pdf

Basics:

There is a core clock that feeds your CPU, I'll call this the base clock.

For my computer, it's 200mhz.

From that clock, the signal is multiplied to drive the CPU core(s), this is called a CPU multiplier, mine is 16x.

200 x 16 = 3200 mhz. This is my factory speed. If I up the base clock 10%, it is 220 x 16, or 3520mhz. If I leave the base clock alone, and change the multiplier to 17, then it's 200 x 17 = 3400.

Usually you are pretty safe just changing the base 10% with no downside. I went 220 x 18, and it was too much.

10-4 I see what you are saying...thats funny mine is running 200mhz but is only x12...I think I'll try cranking it up some what program are you using to overclock it...its a laptop if that matters...I downloaded CPU-Z and that told me alot I forgot what speed stuff I got

ty for the info

can you do the folding with the GPU and CPU?

I'm not sure how you would turn up a notebook. I just barely started learning modern overclocking, so I'm certain no expert, and based on my "crash", I suppose I'm not exactly a good source for info. :D

The new 6800/6811 WU's aren't "work friendly" and generate too much heat. They are perhaps aimed at dedicated FAH systems. I have to take it off-line to work.

CrayZ1 only had the GTX460 GPU3 client aimed at it.

All the teams are taking a big hit in PPD due to the 6811/6800. I had a home computer fry the 450w powersupply last night because of them. This computer had been running 24/7 for a year, and a couple days into these WU, it died.

I guess that I have been lucky with them. I have taken a hit in PPD prediction (11561.6 PPD) but I have only crashed and lost one WU out of ~50 6800s so far. I thought I had stopped the client, didn't, declocked, and applied it. Of course, that caused a crash. The only reason I slowed it down was that the temp had jumped 20°C over normal.

Currently, the one 460 is running at 851/1702/4298 and staying around 47°C with 65% fan.

Sorry to hear about the PSU. Hate when stuff dies and I have to. . . UPGRADE! :joker:

I removed the GTX460 from this machine to build my son's game computer.
I'm replacing it with a ATI 5450. Starting today, this computer will be SMP only under the CrayZ1 name. It is now 18x and 200mhz using the AMD Overdrive utility (free). This does not require BIOS changes.
