Ok, I have a P4 1.7 Willy oc'ed to 2040 mhz.
Runs stable there but hot. core voltage at 1.8v.
This is on a Abit BD7 raid, raid enable (0).
My biggest problem is my ram.
I've tried three types of ram so far.
Crucial 2100 CAS 2.5 , PowerMem with Samsung 2700 chips, and OCZ which I'll admit wasn't any good (I won't count it in the rest of my story below).
Problem is my Crucial and PowerMem will both do 128 fbs if my fsb divider is set for DDR 200 (or 100 fsb) and I oc from there.
BUT if I change my fsb divider for DDR 266 (133 fsb) and oc from there I have NEVER been able to go past 120 with a stable system; WHY? (OCZ was so bad, I won't even count it!)
I have been using the Crucial 2100 CAS 2.5 DDR for several months now, and it works fine up to 120 at 266 fbs divider. But it won't at all past it, hanging my system at startup or as WinXP loads. Get GPF's and all kinds of stuff.
This past weekend I tried the PowerMem 2700, hoping I could get to 128 oc, starting at my 266 fbs divider, but I couldn't get it past 120 regardless to how I set the timings and or the ram voltage! Actually I trashed WinXP twice and had to reload a backup because the ram caused WinXP to produce some kind of error that I couldn't recover from.
My question is why can't I get my ram, any ram to oc my Willy P4 to 128 fbs oc, which I KNOW it will do if I start my ram at the 200 fbs divider? Why does it always stop at 120 mhz oc? I am using the Fixed PCI and AGP setting so my busses won't be oc'ed!
Also I am getting ready to order a P4 Northwood. (I have just ordered some Corsair 3200 DDR tonight.) So do you suppose I will encounter these same problems with my ram and mobo and with a P4 Northwood?
Finally about the cpu voltage: Since my Willy P4 runs at a little higher core voltage than the Northwood, and the mobo shows the higher voltage for the Willy; What does the mobo do to correct this and lower the voltage when I install my Northwood? I have read some about the Northwoods needing the extra voltage; But am I right to assume that the mobo will automatically lower my voltage choices, so I will still be stuck with having to mod my Northwood if I want higher voltages from it?
Any help is greatly appreciated!
Cheers,
Mike
PS BTW, can somebody tell me again, exactly how to figure what my actuall DRR oc would be running, oc'ed, if I start oc'ing it from a 266 fbs divider?
