Manually Setting Your Memory Timings and Voltage!!

I have the same issue as Teej with OCZ ddr2-8500. It will only go as high as 800mhz. And most of the settings in this PDF are not in my 750a's bios.

Do you have a Phenom or Phenom II? If your using a old X2 then it will only go to 800.

Now that makes sense. Yeah, I'm running a Phenom 9500 Agena with the old B2 stepping. oops

I thought that CPU did support 1066 RAM?

MitchSchaft · 05-17-2009, 03:20 AM

So did I. Something's amiss

**Blacksmith1** · 05-19-2009, 03:04 PM

did you flash your bios to the new one that supports the Phenoms?

We fixed this yesterday in that other thread :D

I'm not sure how to enter the correct values for my ram...

i've got 4g ddr2 pc8500 (2x2g modules) 1066mhz, 2.3v

motherboard = 750a SLI

cpu = phenomII dualcore 3.1hmz 550 black.

could this be why i can't boot (unless i hit CMOS reset switch then press f2 to lead default settings + continue)?

can't replace my BIOS to resolve compatibility issues either, checksum error. Could incorrect ram settings be causing this?

I started a thread on it, but this seems a better spot (+ i added more info)

you have the xfx 750a .you need to find out your timings to set them manually. you can set your voltage to 2.1 volts but that's as high as this board goes.
in the just woot settings in bios there is a cpu configuration you need to go in there set the timing to both, t2 (IIRC), 533, and the set the cas, trp and such to whatever is on your mem.
the voltage settings are additive. turn it all the way up, and you will reach 2.1

what brand you have is as important as any other info you give on your hardware.

hi just got a member of these boards as well
bougth some new memory for my nforce mainboard

geil 1gb quad kit
timing 5-5-5-15
voltage req 2.2-2.4

the problem i now face is the pc wont boot with more then 2 cards
on default settings as soon as i put int eh 3th i get the error message

tried reading that pdf file but didnt make me any wiser
