ASRock 939 and Athlon 3700 problem

[jarvo]

I am currently running:

Athlon 3700+ San Diego
ASRock 939 Dual SATA II
512x2 OZC PC 3200 2.5-3-37

I have my CPU at 245 x 11 giving me 2.7GHz. This thing absolutely screams but my memory is letting me down because it wont boot unless I cut the ratio to .83 making it run at 192mhz X 2 (DDR384). I figured I would try to set the multiplier down to 10 and the FSB to around 260 making the Memory run a little over 200mhz. When I set the multiplier down in BIOS it boots up fine and reads the correct clock frequecy..but when I get into windows, CPU-z says I still have the 11x multi and my CPU is running at 2.86ghz. The system is way to unstable to run at this clock speed. Everest home edition is also saying I am still using the 11x multiplier. When I go back into BIOS the multiplier is set to 10x... This is confusing the hell out of me. Does anyone know what the problem might be?? Am I going to be stuck with a slight performance loss?

Thanks!

a couple questions....you are sure you are setting the multiplier to 10 and not 10.5? and what ram are you using? OCZ value ram? or is it some type of VX ram? or platinum?

Its OCZ value ram..and my mobo does not allow you to set .5 multipliers. Like I said before...the Bios POST screen displays the clock speed it should..but CPUz and Everest display the clock speed with a 11x multi. I know it is still using the 11x multi because it is extremely unstable.

I had the same problem with my system (multi not working in BIOS) until I upgraded my BIOS from 1.2or3 to 1.5.

My Opty 148 stable at 249 (and not a MHz more ) x11, stock Vcore and cooling. You have changed the CPU to North/South bridge down to 800MHz (HTTx4) or 600MHz (HTTx3)? RAM Voltage at high= only 2.7V (but they are 2.6V sticks IIRC and seem to OC well from what I've read).

Unfortunately, with these boards and stock BIOS you don't have many options for your memory speed. I think the OCWB01 BIOS added a couple more but I haven't tried it (no floppy drive ). I don't have the link handy but google is your friend. From memory it added a 1:2 memory speed option so you may get a bit more out of your RAM. There are also VDimm mod how-tos out there to give you 3V+ to RAM if you want to give 1:1 a go.

There are a few forums around with Asrock sections and a few members that really know this board.

I ran into this same problem while overclocking. I tried to bump the multiplyer down to 10 on my 3500+ Venice and when it POSTed it read the proper Ghz but in windows all my utilities said i was still at 11x multi. Havent figured out the problem, but im glad i found this topic. I will be keeping a close eye on here.

I think i may be on the bios that came with the board, i saw a 1.5 out not too long ago, maybe i will update to that and see how things go.
