**The ASrock 939dual-SATA2 (ULi M1695) thread**

I`m trying to trawl through the thread to find out why my DDR400 memory is registering as 333 instead of 400 and failing... anyone care to save my soul and a nights sleep for a quick answer? :D

x2 GeIL 512MB PC3200 DDR400 ram

its not recomended to install the usb drivers from asrock you should stick to the standerd Windows XP ones

It said it before i installed any usb driver. I thought it was saying this because i diddnt install a driver for USB because i was told sp2 has its own.

But i still get this yellow message with or without the asrock driver.

USB 2.0 is enabled in my BIOS :confused:
 
With a little more fiddling and a new BIOS version, I've got my A64 3000 up to 2.35GHz on this board (9*260, but the board slightly overshoots the mark on the HTT base speed setting). My cheap and cheerful Crucial is taking the overclock to 217, though I've had to drop it to 2T because it wasn't completely stable with 1T.

With my cooler on minimum speed, a single case fan (intake - my CPU cooler doubles as case extract) on minimum speed and a stock 7900GT cooler dumping heat inside the case (I don't trust 7900 cards, so I'm leaving the stock cooler on until the guarantee expires), my CPU still idles at 36C. A good result.

I want to fiddle some more, particularly with memory settings, but the new BIOS hasn't fixed the one problem that is really bugging me with this board:

My HDD is not detected after a reboot or shortly after my PC has been on. I have to power down, leave the PC off for at least 10 minutes and then power back up.

I have a Samsung Spinpoint P SP2004C, which is set to act as an IDE drive because I couldn't get the SATA drivers to install with this board. It's connected to the SATA2 connection on the board and the BIOS settings are set to IDE mode for SATA2 controller and strong driving strength.

Any ideas?
 
I recently installed the latest build of Vista on this board, well impressed so far, smooth and solid, only one unknown device with an exclamation mark needs investigating, hopefully wont be going back to XP :)
 
Slight change, I picked up a 4000+ SD from the members market and with a bit of fine tuning have managed to hit 3GHz on air!! 250 x 12 @ 1.55v.

I've got G.Skill PC3200ZX 2x1gig in there running 3-3-3-8 at 1t at 200MHz. As soon as I go over 200MHz for the RAM it doesn't want to know though, which I figure is probably a vdimm problem. It's a shame about the vdimm on this board, my Abit NF7s can offer up 2.9v but this struggles to offer 2.7v at high setting.

Got some PC4000HZ on the way, hoping that can manage to work at 250MHz. Fingers crossed.

SuperPI 1M is now 29.2s. :D

your PC3200ZX sticks with there Infineon CE-6 chips should be running 2-3-2-5 at 400ddr 2.5-2.7 Vdimm, you should loose 2 seconds off your 1m pi score with those better latencies.
1.55 vcore, is that after a voltmod?
 
Yeah, condictive paint voltmod. Was running a 3700+ at 2.75GHz, I know it's not much of an increase but it's one of those milestone targets.

I'll give those timings a try, thanks for those.
 
Those timings should be set by SPD with your low latency ZX sticks, so im unsure how they managed to get set so slack on your mb in the 1st place. Anyway you should get better results with those HZ sticks you have on the way, mine run at 250mhz with just 2.4 vdimm, Samsung uccc run real well on low voltages.
 
SuperPI 1M now 28.902s using those timings.

Reason I'm not using SPD is it wouldn't boot with timings set to auto for some reason. So I set some slack timings to get it running.

I'm hoping for a decent result with the HZ, which if they run as expected will mean the ZX are surplus to requirements.
 
tbh the zx and hz sticks will perform around the same, if you can keep those zx nice and tight, there gonna give just as high bandwidth as the hz which struggle to do CL2.5 at anythin higher than 230fsb
 
as i said, the zx's run much better latencies than the hz's, i recon high frequencies will win out but not by much, running on a divider does nothing detrimental to performance with these a64 cpus also. worth trying though
