Sandra shows the bandwith the CPU can handle. Thats why IMHO you won't get any better result with 2 channel testing.Quote:

Only the max. bus bandwith would increase!

Where is the VDD mod posted?
Found it:

The P4 can accept more bandwidth than the Athlon XP, that is what i ment. As a consequence of that, the efficiency of DC for P4 is much higher than DC for Athlon XP's
Is there any efficiency of DC 4 the XP?
Thats up to you to decide :)
but i dont see that much of a performance gain
I don't know if anyone has tried tweaking in the voltage with the vdd mod, so I wanted to see really what voltages I needed for the fsb I was running. Less voltage with the vdd mod to me means less chance of killing my parts. I was looking for a stable system with no screen flicker.
Stock mobo mem 195fsbx10.5 2.63v vdd 1.58v
Run prime, no screen flicker
10x205fsb 2.77v vdd 1.58v
Will not run prime, screen flicker
10x205fsb mem 2.77v vdd 1.70v didn't go lower
run prime for an hour, no screen flicker
9.5x215fsb 2.9v 1.70vdd
prime error, screen flicker
9.5x215fsb mem 2.9v vdd 1.79v
Prime running about 2hrs., no screen flicker
I would try tweaking in my voltage, you may not need as much as you maybe running for a stable system.
Used 2 sticks of memory dual channel , mem timing

Same opinion! It was a not-2-b-answered questionQuote:

;) or what u guys call this in english.
What's about that screen flickering? I believe it's a kind of overheat. Maybe also the mosfets? I can run Prime @ 224 but only 221 is workable because of this f***ing flickering.
Its a retorical question i think :)
dc gives me another 50mb'S in sandra membench.
Al ittle bit of improvement...burning in goes a long way :)
