How much can I overclock with DDR2 533

Hmm... what about OCing a e6600 (stock HSF) on Intel 975XBX with DDR2-533?
How much can you OC that?

The bad axe hasn't been added to Wusy's guide yet :cry: .... hopefully soon :D


Anything to look out for if/when doing this?

Price upgrade to 667 RAM from 533 is negligible. Go with 667, you'll get a much better OC.

I am upgrading my motherboard and CPU, and upgrading RAM is too expensive, a 2.3gh overclock is good enough for me, I might push it up alittle bit with memory overclock.

So with DDR2-533, the 1.86ghz e6300 can hit 2.2 with stock cooling? Go for it OP :D

Sorry to ask again, but with stock HSF, the bad axe board, ddr2-533 (4-4-4-12) and an e6600 how far is possible?
Is this even advisable?

At least 3.0GHz. If it doesn't, I'm shocked.

You're not going to get good performance but you will get that speed.

Hmmm.....and therein lies the problem. OCing here would no longer provide the 1:1 ratio....

Not sure if I should try this or not...any thoughts/suggestions?
How much of a performance hit are we talking about? Is this even worth attemping?

I realize the better idea would be to get some faster ram and then OC, but with 2GB of this nice DDR2-533 I hesitate...well that and the current prices of ram these days... 8O
 
Well with a 3.0GHz OC.... you would be running a 333MHz FSB, which gives you a 1332.5MHz, when divide by two gives you 666.5 or say 667MHz. Thats the RAM you should be running it with. Otherwise you are at least 100MHz from running parallel. The exact performance hit you'd take varies from task to task. I know for sure that your SuperPi scores would suffer.
Gaming or other real world tasks are what would really interest me to see the difference.

Alrighty, thanks for the info......much appreciated.

More things to consider for the future.... 8)
My system's great so far..just was curious.
Thanks again.

I am thinking of using a P180, with Stock fans and Stock HSF on CPU, what is the 1:1 ratio of RAM? I read the RAM FAQ and it didn't say anything about it.
 
A one to one ratio can be calculated by taking the rated FSB, and dividing it by 2. To corroborate that, take the bus speed and multiply by 2. Say you have bus speed of 333MHz, a FSB of 1333MHz and a clock speed of 4.662GHz. You divide 1333 by 2 and you'll get 666 or 667. Multiply 333 by two and you'll get 666 or let say 667. Thats the speed of the RAM you should use.

Well I don't need 4.6GHz overclock, and if thats just 667 RAM then 533 should do fine for a moderate one.

After thinking about it, any performance gain from 1:1 ratio is probably a lot lower then adding a few hundred MHz to the overclock, I will probably just overclock to 2.7-3GHz.

The E6300 is perhaps the best overclocker yet and coupled with a good set of rams and other components, it can get up to 4Ghz! With 533 well pretty much it's running 1:1 ratio and overclocking it depending on that ram you are using you can reach maybe a mid to high 2Ghz. For sure the easiest way is just to lower from 533 to 400 and then just overclock the cpu from then to it's max stable frequency.

o sry....i have a ds3...


i thought i saw a "d"

but u can still get to 3.2 most likely

dude there arent that much difference from the S3, just the capacitors and a couple more features.

Spec whiles for OC'ing is the same
