8KHA+ Dividers (epox tech help)

[{pms}fishy]

Ok I have the 8KHA+ and my stick of mushkin PC3200 that just came back today from RMA. I have been running the system at 195fsb and my Crucial 2100 with my memory speed set to 100mhz (3/4 memory divider).

Anyways I stick the PC3200 in and boot up, go into BIOS and change the memory speed to 133mhz, now I cannot boot into windows, it will post but hangs windows. Im am wondering if the memory divider also effects the PCI bus. If not what is going on here? I cannot get into windows even at 170fsb with the memmory set to 133mhz. Im going to go play around with some settings some more and see if I can do any better. All help will be appericated. Thanks.

what have you got the Vdimm set to ?

try running at 3.2 (may kill things)

My 8KHA+ with PC2100 Crucial won't go past 145 at the 133 setting.
It's my understanding that your pci bus is also running whatever your fsb is set to, as there is no 1/5 divider on this board.

How high can you get to when you set the board to 100MHz?

Was wondering myself if I purchased some PC3000 or so, if I could get any more out of my system...so keep us posted with your trials, eh?

BTW, Welcome to the Fourm !!

Do you have you "jumper" set @ 133 and not 100?

Nah its Mushkin, does not get any better with more than 2.8v Im running 2.7 now. Ive gotten to 170fsb agressive now. Thats still no where near teh 200mhz that its rated at. They also said that they handtested it on my MB to 200mhz 2.5-3-3-6-2 Am I wrong in assuming that it should be able to do 185 2-2-2-6-1 4-bank?

With the memory set to 100mhz I can take the MB up to 197fsb stable BIOS release 5/29/02

Its a setting in the BIOS, and Yes I have it set to 133 thats where I want it to be.

I know it's in the BIOS, I have the same mobo as you if you look @ my sig, BUT ON the Mobo itself is the JUMPER set for 133.

Ok I switched the jummper around and that makes no difference. I still cannot get it to go.

Please try at 3.2v.

Just for a test.

What bios version, you might want to change to 8khal00.bin

I have tried the 8khal00 BIOS but had worse luck with it before. I would really rather not put 3.2v to the memory yet. Ill save it as a last resort.

Now at 3v 180mhz agressive. Shouldn't memory thats rated at 200mhz be able to do 180 on lower voltages whats going on here? Off to e-mail mushkin.

The difficulty is that increasing the VDIMM also boost the voltage to other parts of the board.

My 8kha+ also needed high voltages to run high FSB even though the memory would probably survive on less.

If you use the 3/4 memory devider with 3.2v then id expect you to get a bigger overclock. My board would run 225fsb on 3/4

I had a stick of Mushkin that i returned due to its performance. My Samsung 2700 will run up to 195MHz on the 2312 @ 3v and the Mushkin 3200 wouldn't even do that at 3.2v. If my Samsung could handle that kind of voltage, I'm not sure just how high it would go(craps out over 3v). Oh, and yes, Cas2, 1T, 4-way, the works....everything set to most aggressive.

It does not make sense though. I ran 2.9v for the ram before when I was at 195 fsb. So that should be all that I need to run the MB at 195, but the darn RAM sucks. I sent Mushkin an E-mail, lets see what they say.

You mentioned your mushkin was tested and rated cas2.5.
Some sticks are very sensitive and are unable to run cas2 even tho they run very high at 2.5. I've heard some samsung2700s are this way... they can do 200fsb @2.5 but can't even do 166fsb @cas2 (some, not all).

Tried 185 2.2-3-3-6-2 Froze within 1min @ 3v
