Undervolting, useless to go for half multiplier CPUs?

Considering undervolting cannot work with half multipliers, therefore underclocking your cpu usually by 100 mhz, is it better to opt for P8600 over P8400 or P9500?

 

So what point are you trying to make?

 

I asked a valid question.

 

Honestly, the difference in clock speeds is not significant. I would still choose the P8400 if upgrading meant higher cost, despite the half multiplier.

 

For the most part, there is no upgrade cost going from P8400 to P8600 when you config dell's business line laptops, which is odd, but anyway, I'm looking at the outlets and wondering if I should filter my processor to P8600. If I were to go for P8400, i'd undervolt to 2.2 ghz i believe, so I lose 200 mhz from p8600 undervolted.

 

P8600 has a full multiplier, you wouldn't lose any speed with that. The max you can lose is 133MHz since it's 1066MHz FSB (quad pumped, so 266MHz per multiplier). If there is no price difference, go to P8600.

 

Undervolting != underclocking

You can undervolt without lowering your clocks/multipliers.

 

But if the processor has a half multiplier (ie. 9.5x), RMClock will only run the processor at the highest whole multiplier (9x), because it doesn't support half multipliers. So in that case you would lose some megahertz.

 

Ah. Then in that case, I would not bother with half multipliers. I've never had a CPU that used them, and I wouldn't really want them anyway.

 

Only on the new Intel and AMD processors this occurs
This is because Rightmark does not fully understand those processors

On my AMD Opteron 185, I can clock it from 5.0, to 5.5x, all of the way up to 13x. Every half multiplier works

K-TRON

 

So am I losing too much if I go from P8600 undervolted to P8400 undervolted? It's not really a price thing, it's just that in the dell outlet, E6400, I can broaden my search if I cannot find one with the specs I want.

 

cpugenie supports half-multipliers for undervolting http://cpugenie.com/

 

P8600 DOESN'T have a half multiplier, therefore you lose no speed.

 

2.4GHz vs 2.13Ghz; your choice if it's worth it. Also, you don't have to undervolt, and in future versions of RMClock, the processors might be supported.

 

I didn't say it did.

 

I would go for the P8600 if the prices are marginal.

Have you tried out CPUGenie? It fully supports new and old C2D cpu's

 

Looks like I might have to pay for it? and no I haven't, i'm just following your guide with RM clock lol.
