Epox 9npa+ultra and ballistix

[bwanaaa]

Just started testing the following setup:
4800x2, epox 9npa+ultra(80405 bios), and ballistix 2x1gb set
memtest + errors in test #4
When i set fsb to 300, then ram freq is 245
when i set fsb to 250, then ram freq is 216
LDT is 3 and RAM is 3-3-3-8
Why does my epox board always set a divider? I tried setting the ram freq to 250 (instead of AUTO) but I get no boot? I know it's something stupid I am overlooking.

That's because of your multiplier. Make sure that you set it down so that the 250HTTxmulti equals your stock CPU clock and that it doesn't go above.

let us know how it goes. im considering the same combo as well and would like to see some result before i tak the plunge;)

air cooled 65degC load dual prime OK
FSB=300 multi=9, +.2v on vcore, 2.7 ghz cpu -> RAM goes to 245

in this case your formula would yield 245x9=2205 - well below the 2400 of the stock cpu. setting the ram freq manually to 250 still yields 250x9=2250. Still below the 2400 'ceiling'

Interestingly, even though it's dual prime ok, memtest errors out in test #4 at fsb 245.

even more odd, when the cmos is cleared and the board is left to auto with everything at stock settings(RAM 3-4-4-8) (200x12), memtest reports that RAM is at 160 mhz (ddr321). What's up with that?

Like I said, that is a conflict of multi/HTT/divider.

But anyways you should consider doing a BIOS update and try to hunt down ones that support X2's even if they are BETA's. Also Balistix are known to take higher Vdimm at high freq so you should try working with that and I would recommend that you active cool them in that case.

tnx for the reply. Obviously, my density exceeds my luminosity - can you elucidate the concept of 'conflict' vis a vis multi/HTT/divider.


multi x FSB gives cpu speed

HTT and divider are ram properties-how does multi conflict with that?

You need to have a multi on par with HTT so that you don't exceed your CPU clocks over it's limits (that's where OC'ing comes in:)) or otherwise it will become unstable unless you do some tweaking.

Once you reach your max HTT with 1:1 that's where dividers come in.

I FIGURED IT OUT!

Ballistix likes 3-3-3-7 not 3-4-4-8

I got my clocks up to 300 x 9 (RAM freq 250) but this required +0.2v on the cpu resulting in a core temp of 45 deg idle and 62 deg load with the fans full on. This config is DUAL prime stable for 18 hours to boot!

Coming down to 295x9 (RAM freq 245) allowed me to reduce voltage to +0.1 v giving a load temp of 51 degrees with the fans only half on and relatively quiet. Amazing difference for 45 mhz. and not worth it for me. Really, if i wanted hot clocks i'd put my storm on it for 2.8 ghz or go for phase change for the holy 3 ghz.

Presently I am at 2655 mhz - an easy 10% overclock that is prime stable and not too hot.

FYI, mushkin's 2x1 gb kit (991434) at 2-3-2-6 got to 250 mhz fsb and bandwidth was equal to the ballistix at 270 fsb. So I am still ahead of the mushkin's tighter timings with the ballistix.

I've heard that the ballistix can do CAS 2.5 so I'll try that next but I think I'll need to tickle all those unusual little parameters like skew and drive strength and that WILL take TIME. Unless someone has a few clues? :)

For Skew Value you can either try 0 or the max of 255 and see which one gives you better results, for me both work the same. As for DRAM Drive Strenght try either 7 or 8.

Try altering the Memory Frequency in "Power BIOS Features"

On my 9NPA+SLI, I've found that you need to play aroudn with the Memory Frequency to get the multipliers to match. Whichever setting gives you a 1:1 ratio between memory frequency and front side bus should be fastest. At least, that is what is fastest for me.

My Memory Frequency is currently set to "DDR400 (200mhz)" but when I boot up, the POST screen shows DDR500 @ FSB speed.

Where are you seeing the Drive Strength option in the BIOS?

Also, when you say 3-3-3-7, you mean Tcl = 3, Trp = 3, Trwt = 3, Tras = 7, right?

drive strength is under dram submenu in the advanced chipset menu of the bios.

yes.

I was trying to go above 300 mhz on the fsb - the crucial doesnt like it. I know my epox can handle up to 340 fsb if i slow the memory freq down to 100 - but no dice at 200 mhz. does anyone have ballistix running at
8 x >300??
