E6400 vs E6300

[tran1981]

I'm building new system. I already got OCZ Platinum with P180B case. I can boot with one module and then change the bios for the ram voltage. Which one is better with DS3 or S3? I'm leaning toward the S3 since not much difference. How far can my ram goes if I decide to get 6300? Can the E6400 oc to 3.2ghz easily?

My PSU is an old Enermax EG651P-V(E). Enough power for latest GPU?
+3.3V 40A
+5V 46A
+12V 24A

If you're looking to get 3.2 Ghz, definitely get the DS3, along with a 24-pin power supply, which is required. (20+4 pin works fine, too)

 

[tran1981]

I thought the S3 is almost the same as DS3(better caps) with different ethernet controller. I think my psu has 20+4. Should I get E6300 or E6400?

Unless you want sky high OCs, the E6300 is fine.

You can get sky high with the E6300s too, but you'll need damn good RAM & likely the P5B Deluxe.

The DS3 still hits very high FSBs though.

I heard that the new batch of 6400 doesn't oc well? With 6400 I don't need good ram

With E6400, all you gotta do is set the FSB to 400 and you're ready for 3200 @ 24/7.

FTW.

fyi: with the 1402 bios my P5WDH can go up to 550fsb and it unlocks the multi downwards.

Does higher FSB put more stress on the CPU plus mobo?

Unless you've got the new version, this one: link, then it doesn't. The +4 in 20+4 pin doesn't refer to the white, square "P4" plug that power supplies have had for years now. It means that it's a 24-pin psu, that can power the new motherboards, which require a 24-pin power supply.

The +4 touches the 20-pin plug, when both are plugged in; they go into the same socket, in other words. The only reason that any psu manufacturer is making them that way, is so they can still be used with older motherboards that only require a 20-pin connector, along with newer motherboards.

I don't have the new version. Time to go hot deals to look for a new PSU.

Or I can get a 20pin to 24pin connector. I think my PSU can handle the power.

P5B Deluxe can do 650

Can do & will do are very different.

Also, i believe all 965 mobos have downwards unlocked multis.
At least all OCing ones do.

Should I get E6300 or E6400? Can u lower the multiplier in E6400 and get the same FSB as E6300? I have OCZ ram so I think I can do higher FSB for faster system.

You can run the E6400 in a P5B or a DS3/DS4 with a 6x,7x, or 8x multiplyer.

I can do 510x6 = 3060Mhz CPU

However, with the P5B Deluxe I read that at 400Mhz FSB the strap timings are better than at 401. Some people can't get good stability until they go to 401Mhz or higher because the timings are more loose.

You can just plug your 20 pin connector into the 24pin spot on the DS3. I have an Antec truepower550(20pin) powering my E6300, DS3, 2gb ram, 2 hard drives, x1800 xt

 

[tran1981]

I heard you can do that too if you have a good PSU. I'll try that before running to get a new PSU. Still debating between the two cpus. I don't want to spend a lot of $$, saving for new GPU w/ DX10. Right now I'm using 9700pro w/ P4 2.4C (Dell 8250).

 

[Conky]

I'd say E6400. The price difference isn't that big and you get an extra multiplier. Lots of guys hitting 400fsb easy which gives you 3.2GHz.

I'm running my E6400 at stock right now(my system is loaded with drives and fans) but when I can afford a decent motherboard, DDR2 RAM, power supply, and a PCI-E videocard I will be shooting for 3.2GHz. Heck, it runs so fast at stock it's gonna blow your mind compared to that old 2.4C. :laugh:

I really think that with a good mobo, all you need is the E6300.

But i think the only mobo that can consistently reach 500 right now is the P5B Deluxe.

7x500 = 3500 MHz, which is the most i'd hope for out of an E6300 with any mobo.

Whereas with the DS3 & P5B Deluxe & others hitting around 450 for sure, with an E6400, you have 3.6 GHz guaranteed as long as the CPU can do it.

IOW, no mobo limitations will hold you back with an E6400.

On a budget tho?
Easily i'd recommend the E6300.

 

[tran1981]

new mobo comin out p5b-e is also a good ocer and cheap. Too many choices...

 

[tran1981]

Can 6400 hit 3.6ghz easily? Is it the mobo limit or cpu? 450 fsb doesn't seem high, maybe cpu?

That depends alot on memory too. When you go above 400Mhz FSB every DDR2-800 memory will be in overclocking territory. You'd need either good memory or faster memory.

I think I have the same PSU as you. Mine is an older one, purchased originally with a K7 thunder motherboard. The connector should be 24-pin. Mine had several adapters - one for the K7 thunder motherboard (a custom design) and another adapter to use with 20 pin motherboards. With all adapters removed, it worked perfectly in my current 24-pin Abit motherboard.
