Overclocking 8200 and 8500 - any difference?

[amdbuilder]

Hi guys,

I've searched a lot online and in forums and am too stupid to work out what might be a very simple question but I've never overclocked before so am only just getting my head round it all...

QUESTION:

Seeing as the only difference between a E8200 and E8500 seems to be the multiplier, am I right in thinking that maybe if I'm gonig to overclock it makes absolutely no difference which one I buy as I'm going to be overclocking the multiplier to max on both anyway? The 8500 doesn't cost that much more but still, if it's basically exactly the same chip but they've just chosen to multiply it a bit more isn't it a total waste of money to get it?

This really confuses me because something tells me there MUST be more to the more expensive 8500 than simply just it being multiplied slightly more i.e. is it inherently faster/ more stable and therefore is it actually inherently more overclockable....

AARGH!!!!!

Please help a total overclocking newbie!!!

THanks!! 😀 😀 😀

Intel CPU all have locked multiplier unless you buy the overpriced Extreme versions ...

that's what you with the more expensive E8500, faster stock speed due to a higher multiplier, and higher OC-capability.

e8500= 9.5 multi
e8200= 8 multi

Say you want to run 4.0.
You need a 500FSB x8 to get 4.0 with the e8200.
You need a 421FSB x9.5 to get 4.0 with the e8500.

With the e8200 you will need a motherboard that can handle 2000FSB AKA x48 or P45.

Also if you get the e8500 you might get the new E0 stepping that can OC to 4.5ish on air. The C0 steppings will be a tad hot at 4.0 on air.

Also to OC the e8200 that high you need 1066 ram and you would be fine with 800 mildly OCed for the e8500.

Furthermore, when you take binning into account, the E8500 is more likely to hit a top speed than the E8200.

When they were first released, there definitely seemed to be quite a bit of binning going on with the E8200 not hitting the same speeds.

I'm not sure if its as much of an issue as before.

Thanks guys I thought it was a simple case of increasing the multiplier*blush* but now I see not!

As I thought the 8500 is innately faster then and can go higher. I shall spend the little bit more for that then instead. Thanks guys!

PS I searched a bit on "binning" and I guess that means chips that don't make the grade to run at 8500 speeds are branded as 8200?

Ok just read the excellent CPU guise which explains binnig perfectly.

Thanks guys!

Ok, I've read a bit more on this stuff and am thinking of getting a 8500 but can only find the C0... I've read that the E0 is actually slower because of slower cache so although it clocks faster the overall speed is the same.

What do you think of this?

I always say buy the highest multiplier you can afford (when getting non extreme) when planning to OC. I have a E8500 C0 stepping and it took a bit of effort to get 4.37 stable because of heat. Then again there is now the E8600 with a 10 multiplier Apples to apples an E8600 might get you 4.6+ on good air cooling.

^but what about Q6700 vs Q6600? multi is not the limiting factor in a Q6600 overclock, it has a stock FSB of 266 which when put to 400FSB is pretty much the max if using the highest multi... the slightly higher multi on the 6700 is kinda wasted because anyone who has a Q6600 puts the multi lower anyway...
