abit ic7 latest bios ver 17, 2.4c, komusa pc4000 dual channel hyperram running at spd timings....
Hmm, could be many things...
What I would do:
First: Optimized defaults.
- 800 PSB
- 5:4 FSB:MEM
- AGP/PCI Fixed 66/33
- up vdimm 1-2 steps
Manual timings on RAM:
3 7 3 3
The last options at the same page:
Auto
Auto
Auto
Disabled
Disabled
- disable E1394 and second sata controller (if you don't use them)
- select you boot-order.
Try boot at 200FSB
Then use ClockGen or SetFSB and try upping the FSB.
WCPUID won't recognise the changes, but CPU-z will...
One other thing you could try is to max out the memory at 1:1 first. Up vdimm to 2.8 (safe IMO), then try...

thnx for the input.. Ive tried the first on your list
psd 800
agp fixed
5/4 ratio
vmem/2.8
timings 3844. unfortunately that is a no go but ill try the other stuff when i get home tonite
incidently, this memory really cranks 1-1 ive had it up to 285 (booted) however the reason i want the 5/4 ratio is im trying to isoate the cpu from the memory( suspect its the memory cause it loves hi-voltage). but without isloating the cpu from the memory i cant really be sure what component is failing at very hi frequencies..

Is your komusa ram A-Data? I hear it is.
I bet this is another compatability problem again with the IC7 and ram! Do you have any other ddr to try try out the other ratios with? Even something cheep to see if the other ratios work. I'm thinking of trying the Komusa but if the other ratios don't work it'll really suck.

yep u hit it on the head! the pc4000 &4200 hyperram employs the adata chips. I ultimately plan on runnin this setup at 1-1 but to determine what component is failing ,i have to be able to seperate the ram from the cpu and thats where the 5/4 ratio comes in handy.. no use in doing a vmem mod to ultimately find out its the cpu failing and not the ram.. aside from this issue, im really pleased with this ram. It was inexpensive and runs darn fast. ill bet the pc4200 stuff can really crank..
If abit support cant help then ill guess ill have to get some cheap ram just for testing the cpu... that sux....

finally found the answer. simply changed the auto timings to manual and presto the 3/2 5/4 dividers work. thanks everyone for the input and help
