IC7 and mem at 256??

I fired up the board today and it locks in the exact same spot that Opps does. If I set it at 255 I get into windows no prob. Then using SETFSB I was able to get it up to 268 1:1 with 2.5-7-3-3 and run sandra cpu & mem test.

My board and ram do the same thing as everyone elses. How do I get setfsb to work on my IC7? I tried turning off HT and rebooted but it still was a no go

Steve

serfsb does work, BUT cpuz and wcpuid don't show the correct fsb/mem.

Ok but when i raise the fsb with it my benchmarks go unchanged

It should change 3Dmark scores.

Ah the one test I didn't try :D

Seems to work :D

Does anyone tried four sticks of 256 MB OCZ PC3700 Gold with regard to the thread topic?

You'd need to reinstall WinXP without HT.

But wcpuid can read the correct speed too:

I think you need to re-read the thread topic. It doesn't have anything to do with running 4 sticks of 3700 memory.

I think it is just another parameter. Running two or four sticks on the IC7 in DC mode at 256+ (1:1/5:3) is maybe a hugh difference.

I have tried running 4 sticks, and it doesn't help! I get a more stable and higher clock 1:1 and 5:4 with 2 256 sticks instead of 4-256 sticks.

Thanks for the info. This will prevent me from buying another two sticks. I will wait for mem that's capable of running at 270+ in 1:1 mode.

Just so everyone knows I tried last night to run just 1 stick of ram at over 255Mhz and got the same result. I've also found this board will not run at 300Mhz FSB+ using any mem ratio and 2 sticks of ram but with one stick I can do 318+

I swapped out my IC7 and updated bios, and now I get the 256/ on boot. I can also set to 255 and boot into Windows.

Does this limitation affect the IC7 in 5:4 mode?
ie does someone lucky enough to have a P4 running at 300fsb
have any trouble with memory at 240MHz?

with 4 sticks it doesn't help that real vdimm is 2.76v max

i tried 4x 256MB ADATA PC4000 sticks on

PX865PE PRO2 with 2.85v vdimm max error free so far is 261mhz 3-4-4-8

IC7 with 2.8v vdimm max is 237/238mhz 3-4-4-8

4 sticks sees max oc drop alot compared to 2 sticks max with 2.85v being around 274-277mhz on PX865PE PRO2.. can't go past 255mhz on IC7 still :(

My IC7 wont do over 300FSB using 3:2 or 5:4 unless I use one stick. If I run one stick I can go all the way to 318 with the stock NB cooler
