Very promising oc's you guys had.

Waiting for my 4400+ ... if i can hit 2700+ with water im a happy camper.

I'll be getting my X2 in a week or two, I want to see if systool SuperPi times when run in 2 instances are significantly different from just 1 instance. I don't think the Systool SuperPi is a true multithreaded application. Cinebench is a good tool if you want a quick benchmark for a multicore setup, but its not exactly an indication of stability. Now, if only SuperPi + Cinebench could be merged....any coders out there? :)

Just received notification that my X2 4400 is being shipped - should have it tomorrow.

I'll code up something - last time I did that it took 12 hours to complete.. Although it's written in Java it'll use both cores.

You lucky bastage NickK :D

I hope it does work "out of the box" for you :)

Don't forget to get the stepping etc info from the core first before putting it in.

Anandtech have written an article on thier results from overclocking the 4200+ on air. As shown below, thier highest stable OC was 2695MHz

http://images.anandtech.com/reviews/...4200/a64x2.jpg

Performance Test Configuration

Processor AMD Athlon64 x2 4200+ (2.2GHz 512KB cache each) 939
RAM 2 x 512MB OCZ PC3200 Platinum Rev. 2
Power Supply OCZ 520 watt PowerStream
CPU Cooling Thermaltake Silent Boost K8 HeatSink/Fan
Hard Drive Seagate 120GB 7200 RPM SATA (8MB Buffer)
Video AGP & IDE Bus Master Drivers nVidia nForce 6.39
Video Card nVidia 6800 Ultra (PCIe)
Video Driver nVidia nForce 71.89
Operating System Windows XP Professional SP2; Direct X 9.0c
Motherboard DFI LANParty nF4 SLI-DR

Front Side Bus Overclocking Testbed

Processor Athlon 64 x2 4200+ (2.2GHz, 512KB Cache each core)
CPU Voltage 1.55V (default 1.30V)
Cooling Thermaltake Silent Boost K8 Heat sink/Fan
Power Supply OCZ Power Stream 520W
Memory OCZ PC3200 EL Platinum Rev. 2 (Samsung TCCD Memory Chips)
Hard Drive Seagate 120GB 7200RPM SATA 8MB Cache
Maximum OC
(Standard Ratio) 245x11 (Auto HT, 2.5-3-3-7, 1T, 2.8V) 2695MHz (+22.5%)
Maximum FSB
(Lower Ratio) 326x8 (2608MHz) (Auto HT, 2.5-4-3-7, 2.9V) (1:1 Memory, 1T, 2 DIMMs in DC mode) (+63% Bus Overclock)

http://images.anandtech.com/reviews/...4200/326x8.jpg

"In the end the 4200+ appears to be a good-performing dual-core CPU with quite a bit of overclocking headroom. We reached 2.7GHz with a PC Health reported CPU temperature of 61 degrees C at 1.55V. 240 was a breeze at 1.45V, exceptionally stable for days on end, with processor temps generally below 50C with our air cooling. It appears an easy task to reach the highest levels of Dual-Core performance with the cheapest 4200+ if you are willing to overclock a little - and the 4200+ is up to the task." - AnandTech

So far systool gives me a max of 2839Mhz at only 1.5v BIOS :banana: I had to pump 1.7v BIOS into my San Diego to get it stable at 2.81Ghz. I'll probably push her up to 1.6v max.

Nice one NickK! Looking forward to running that

The CPU Overclocking feature in Systool is great, think i'll be using that from now on for OCing. 2839Mhz at only 1.5v uber nice. How many digits were you calculating in SuperPi?

It was a quick test. I ran it with it set to 1million. I've backed down 25Mhz and am trying some benches.

Nice result ewitte!

I think I'll count myself lucky if my 4400 can get 2.7Ghz when it arrives :)

This is odd. It locked up doing multi CPU Cinebench. I upped it to 1.55v and windows will not even finish loading. Went back to 1.5v and it loads fine! Right now trying 2.75Ghz @ 1.475v. That was good enough for Cinebench to complete in 36 seconds (730 score). If I can get this thing to run stable 2.75Ghz 1.45v or so I'll be happier than 2.8Ghz @ 1.7v :) This thing is going to require a lot of testing. I'm off to work right now though.

What's your system specs and BIOS version?

DFI Ultra-D BIOS 5/10-1 (6/18 gave me a LOT of problems). Oddly 5/10 said unknown processor to begin with but after reflashing it now it detects correctly.

2x512MB PQI Turbon PC4000 (TCCD) running 2.7v
ATI X800XL PCIe
Sound Blaster Audigy2 ZS

535W Enermax PSU (new one with two PCIe jacks)

2x200GB Seagate (1 IDE/1 SATA)
8x DVDR burner

Swiftech 6002 Waterblock CPU
MAZE4 GPU Waterblock
Bonneville heater core

Sounds like its time to burn :)

Use a program like CPU Burn as the guide says, but use 2 instances.
Moved my 3500+ from 1.7v down to 1.58v prime stable at 2.75Ghz

Getting that high with such little effort and VCORE is getting me excited. At least of getting a few tests ran at 3Ghz.

Anandtech noted, in thier article on overclocking the 4200+, that heat increased exponentially with voltages over 1.55v. Try find your max stable between 1.55-1.50 vCore and then burnin at those voltages to get everything you can out of the chip before moving onto 1.55+ vCore.

looks like these X2 will need atleast WC to keep them cool at >2.6Ghz

Which is unsupprising as they'll be drawing nearly twice the current.

is there a real world advantage with the dual core? for the price of a 4800toledo you could buy an fx57 and a decent watercooling rig.

In certain apps it will kill an FX57. Although your better off getting a 4400+. They should all clock nearly the same (with the 512KB's having better luck). I don't see a reason why one would want to pay 80% more for nearly the same performance.

Not even close ;) :
TDP of 4600+ (2 x 2.4, 512K) = 110W
TDP of 3800+ (1 x 2.4, 512K) = 89W
X2 draws only ~24% more current

Indeed, and here are XBitlabs' measurements...

http://img260.echo.cx/img260/2834/co...umption9rm.png

Dual core AMD cpus consume less power than the latest single core Intel CPUs :)
