***The Official E4300 Overclocking Thread***

3.4 on stock sounds abit high but 3-3.2 is easily made you will porbally need a aftermarket cooler
any way the reason for the multi down clocking is becuase you have intels speed step on turn that off in the bios and it should run at full speed

Even with Intel Speed Step seemingly turned off in the Bios, the multiplier still fluctuates. In fact, it doesn't seem to matter which setting I have Speed step on. It has two settings; Automatic and Disabled. Automatic is supposed to let the operating system adjust things, and disabled should be OFF. But both settings seem to keep Speed Step on.

On a new topic, I've been tweaking the bios settings a bit today, and after all the different combinations of voltages and frequencies, the best I've come up with is 2.79GHz with EVERYTHING in the Bios set to Default settings. The only thing I've changed is the FSB speed, to 310MHz (310x9=2.79GHz) Anything above that, and it all goes to pot. Even with numerous combinations of voltages, anything above 310MHz FSB causes boot failure.

I'm totally confused as to what settings to have. If I can just get to 3.0GHz, I'll be happy.

How are you spotting the multi going up and down? Does the processor speed flicker up and down under load in CPUz? If it does then it's throttling because it's overheating. You may also have to separately turn off C1E which is like Speedstep, but different.

I'm pretty sure Big.Wayne has done rather better than 2.8GHz with a P5B/E4300 combination, so maybe he can help.

Thanks for that. I've turned off C1E in the Bios, and the multi doesn't flicker anymore. I was spotting it in ASUS AI Suite and in CPU-Z. As for it overheating and throttling back, I don't reckon that was the reason. Under load, it does not flicker, it goes up to and stays at max. It only flickers when idle. And according to Core Temp Beta 0.94, the temp is 43-45C under load. Interestingly, ASUS AI Suite, which is software which comes with the mobo, reports a load temp of 52C (7 degrees more). Which one should I trust?

So if you think BigWayne can help me with the overclock, how do I get hold of him?

Thanks,
Fraser.

You don't, he finds u! :cool:

Hi Fraser I suggest you start a new thread in the overclocking section, would probably be helpful if u snapped a few shots from your BIOS so we can see where you are at?

God I feel like such a noob when I'm in these forums. Please tell me how to upload an image into a post. I clicked on the "Insert Image" button, but it tells me to enter the text for formating? What on earth does that mean? Just upload a picture, don't ask me for formatted text.

Computers, eh?

Ok it's the weekend so I'm pushing mine further.

Currently at 3402MHz (378x9FSB) with 1.5v
Been running Orthos for 30 minutes without issue.

I'll get you guys an 8-12 hour stable screenshot overnight.

Is it possible you could take the screenie with your memory settings and Speedfan (Beta version) open? Also, what BIOS are you using?
 
Noob here - be gentle ;)

Just set up my DS3 / E4300 combo and was about to start overclocking.

CPU-Z reports FSB as 200 and multiplier at x6 (???) = 1200 core speed
Bios reports FSB as 266 and multiplier as x6.

Neither of those seem right to me - i thought E4300 was 200 x 9 (???)

Anything wrong here - or am I reading the info wrong?

Thanks,

Dez

p.s. CPU-Z also says RAM running at 4-4-4-18. I've Geil DDR2 800 that should be 4-4-4-12, so looks like the DS3 is wrong there t0o?

p.s. Update - seems E4300 may drop to 6 multiplier when idle(?) I ran SP2004 Orthos on both cores and then started CPU-z and it still reported x6 multiplier. Strange!

Hi,

Your kit is working fine, because it's idling, and you have not turned off the power saving features, the chip reduces it's multiplier to 6x and the voltage is reduced to make it run cooler, more quietly and at a reduced power consumption.

Have a look here for a fairly foolproof methodology for setting up a DS3 for overclocking.

As for the RAM, if you set the speeds manually, they should show up correctly in CPUz. On AUTO, they could be anything ;) .

Thanks WJA - much apperciated. Will have a go at overclocking tonight ;) Fingers crossed!

I ordered one of these E4300's from OCUK yesterday to replace my E6300, arrived this morning, and been playing with it for a few hours.

My sensible RAM limit is 714mhz, which gave my E6300 a 2.5Ghz everyday run rate. I didn't fancy changing my RAM, as I know this set to be reliable and trustworthy, so thought that maybe I could get the E4300 to 3.2Ghz with the same RAM limit.

My first attempts were not too great, couldn't get it above 2.0Ghz at stock voltage, so I started to ramp that up and see how it went.

Currently, I'm at my target speed of 3.2Ghz with 1.5v. It booted at 1.4v, but fell over when I tried a bit of video coding! I'd read on here that these chips needed a bit more voltage than the E6XXX series, and that's certainly my experience so far.

One thing I've noticed though is that this E4300 idles and loads a good 10c cooler than my old E6300. (E6300 idle/idle = 37/52c E4300 idle 26/41c are the temps I've seen so far). Not sure why that would be, but maybe my old chips heatsink wasn't flat?

I'm going to give it a bit of Orthos this afternoon, I've only run it so far for about 20 mins as a quick check.

I'll have to do all that screeny stuff later too! :)

What are you using to measure temps?

TAT?
