ok so ive had the board because previously i had a PD805 at 3.8 GHZ but i know C2D is better, so when the 4300 dropped i was excited cause it had a higher multi and this board i have hits a wall on the FSB but no matter i know i can get something out of it. more performance than my d805.

so i went and bought one from frys' however im having a problem. when i put that chipp in and i have my latest bios revision mind you(603). i cannot change the FSB in the tuning options in the bios, instead its stuck at 2745 and whenever i make a attempt to change it, it just pops back to 2745. so i thought this board is only capable of 1600 atleast as advertised. so i let it boot. well when i let it boot like this, i expected it not to but it did but it did not boot with this crazy high FSB it booted the proc at 1.56GHZ and the FSB at around 693 or 173 external clock. so wtf is wrong? i called asus they want nothing to do with it. i just want to know. did i buy a bad proc? because it works fine on auto at 1.8GHZ 800 FSB or has anyone else tried this board and processor. also i know this board isnt great and its Nforce4

Was this one of the OEM chips that came bundled with a free motherboard for around $149? If so, many people have been seeing less than stellar results. This really does sound like a bios issue though. That bios is dated from November 24th of 2006. The e4300 only came out 2 weeks ago. My guess is they will need to release another bios update. For example, their P5LD2 Rev 2 board was designed to accept Core 2 Duo chips but they had to release another bios on January 16th of this year to make it fully compatible with the e4300.
 
no it wasnt the bundle i didnt know about the deal and when i went they didn thave that deal any more, i paid 180, but im taking it back, and im gonna get it from a local etailer, or somewhere i can get it in the intel retail box. but i think im just gonna wait till my next pay check and get a newer board with a 680i chipset. fucken asus.
 
this sounds like the old sl2q (i think that was particular one) celeron 300a. If you bought the OEM it was from a different manufacture and hence less quality and you couldn't get it to 450. But if you bought it retail the chances were better that it was from costa rica with the sl2q designator. This is kinda sounding the similar.
 
To get beyond 3.2 orthos stable I needed CRAZY voltage. So! 3.2 it is. Also running 400 x 8 did not work for me. But my memory is OC'd at this point. - G

I had the Fry's chip (tray with combo, did'nt use the board) stable @ 345 x 9. Returned it. Ordered the retail E4300 from the egg now stable @ 375 x 9.

does OC'ing the chip past 3.0 drop the life of the chip? i'm looking at getting this and OC'ing it to 3.0 w/ a tuniq tower but am hesitant to go past that because i need it to last

Overvolting the chip reduces it's lifespan, period. Additional cooling might offset this affect. This core is supposed to support 333mhz FSB so if you were able to get it up to 2.99ghz with stock or lower voltage and extra cooling it should theoretically last as long as any allendale core at 333mhz FSB. Most people are reporting small voltage bumps as necessary to get to 333mhz FSB with stability though. No one has run these chips for long periods of time to tell by how much lifespan is reduced when OCing them.

When OCing Northwoods was all the rage it was discovered that you could overvolt them like crazy and achieve very impressive OCs, but even with very good cooling some users reported chips that were perfectly stable and running cooler than a stock OEM machine would be would suddenly stop working (Sudden Northwood Death Syndrom or SNDS as it was called. Appearantly some people had very maternal feelings towards their Northwoods) within 1 year.

OCing an e4300 past 3ghz will certainly comprimise the life span of motherboard and processor but no one knows by how much. A CPU/mobo that "only" lasts 3-5years is hardly a concern to most people. As a rule of thumb: If you *need* your investment to last more than 3 years don't OC. This doesn't ussually apply to gaming rigs since in 3 years you'll likely be wanting to upgrade anyway. However, with a good temps the highest stable OC you can achieve on an e4300 without raising voltage should be pretty safe which should put you somewhere in the range of 2.4ghz to 2.9ghz based on the reports that I've seen so far.

My k6-2 450mhz has been running at ~600mhz for 5.5years now, but I did that with stock voltage (which was like 2.4v lol).

Flasher702,

Well said! Honestly, let's us pretend that it drops your chips life from 10 years to 5. The longest I have ever kept a chip was 3... It was so hard to let go of that 2800 xp Barton. That being said, my voltage for 3.2 is 1.425... which seems reasonable enough... my temps idle are 21-22 on air @ load about 45 or so. - Gazukull
 
Not having any luck lowering voltage on e4300, anything lower than 1.35v and she no posts. Rock solid at 1.35v core though,. Idle temps are at room temp 22c, full load is @ 44c max both cores running Orthos stress and blend. These temps are according to Core Temp (Speedfan, TAT, and Gigabyte Easy tune are not correctly registering temps. TAT says idle at 45c and load at 70c - I dought that - Speedfan registers 50c and -1c - way to funny - Easy tune says 12c, don't know why don't care, all I know is Core temp is the closest to what the bios reads during idle operation in bios). Have fans set 100%, no errors with mem test, or orthos.

Core - 1.35v
FSB - +2v
MCH - +1v (will probably drop this back down to normal since running @ 667)

Hi all, first post and first real O/C attempt so please be nice!

I just had delivered a 4300 (retail) this morning. Its going on a DS3 board with stock cooling and my aim was 3ghz. My memory is only DDR 533, i know this isnt great but i wasnt sure how far you can push it.

However the most i could get the FSB too is 270 no matter what i do. At this speed (2.43 ghz) the temp is 32c idle upto 53c loaded).

The Vcore was set at 1.45 (i tried higher and lower). I loosened memory settings to 5,5,5,15. I tried 0.1 - 0.4 boosts on the memory voltage. I tried +0.1 on the g(mch) voltage (though i dont know what this does).

The Pci-e is set to 100, or 101 and cia2 is disabled. Mem multiplier at 2x.

I guess my memory is running at 540mhz, i thought i could clock it above its rated 533.

Does this sound like the clock i should get off 533 memory?
 
To add to my above post: I have now set the memory voltage to auto. The core voltage to 1.35. Thehe timings are now standard 4,4,4,12.

The fsb is still 270 and it boots.
 
Yes, it is probably your memory.
You will want at least DDR2-667 if you want to hit 3.0Ghz.

While memory may OC, don't expect crazy good results like you can get with your CPU. Memory normally wont OC to the next class up. I must admit that the small headroom you may have is surprising.
 
thanks for the reply, i dont actually think it even wants to run at 5,5,5,15 only its auto 4,4,4,12.

I also tried a 7xmutilpier and tried the fsb at 280 to be sure it was the memory and it would not post at this speed.

Their is absolutley no info i can find on what kind of speeds people can get out of ddr533, anyone have any info? I guess im getting 270mhz out of 266mhz ram is this correct? (mine is out of a dell!!!)


Im looking at some ddr800 memory now, which is annoying as i brought the 4300 to avoid buying memory (there seems to be *very* cheap ebay stuff -rubbish?)

Last point unrelated to O/C, i noticed my fan keeps stopping, at first it would keep beeping at me until i turned off the notification. It is now stopping and starting as i type - i can only think this is because its running too cool at 29c as this doesnt happen when hot.
 
Well, the E4300 will get you from 1.8 to 2.4 on DDR2-533 RAM.
The E6300 will get you from 1.86 to 1.86 on DDR2-533 RAM.

DDR2-667 will get you to 3.0GHZ on the E4300
DDR2-667 will get you to about 2.3GHZ on the E6300

DDR2-800 will likely be more than you can the E4300 push and may get you to about 3.2-3.4GHZ.

DDR2-800 will still really only get the E6300 to about 2.8GGZ which is still less than the E4300 on DDR-667.

DDR2-533 will not let you overclock any Core2Duo significantly except the E4300. The E4300 will yield a 33% overclock which is very nice but is far from pushing the limits of the E4300.

My personal preference with the E4300 would be for DDR2-667 since that takes the CPU to a comfortable 3.0Ghz. Going beyond this yields minimal performance differences that are really noticed but does involve more risks. Of course if you can get teh DDR2-800 for about the same as DDR2-667 go for the faster ram just for leeway.

The E6300 gets REALLY pricey when you need to start looking at DDR2-1000 to have it hit top speeds since DDR2-800 is not sufficient. This is why I tend to look at the Core2Duo options as sort of E4300, E6400, and E6600 as reasonable. The E6400 will let you push the CPU to the limit with DDR2-800.
 
thanks very much for that replym,, very useful. Ive actually found 1gb of adata ddr2-800 on ebay for £45 which seems ridiculously cheap ($90)
 
well I'm at 3375mhz stable 8 hours of prime. Thats 375fsb. voltages are set on auto now, but I will tweek them over the weekend and set them manualy if I see that they seem to high. CPU highest temp is 41c. I have gone as high as 395fsb, but it fails prime about 18 minutes into it. Anything so far above that has been a no go.
 
Wept great salty tears of grief, did I, when I retired my 2000XP. She and I sailed many a stormy sea together, arr, did we. An' soon I be saying farewell to me 3500 64, I shall, and surely I shall see them both once more, hopes I, in calmer, warmer seas...

I Have DDR2 667 - S3 - E6300 running at 3.25GHZ - 1.28Vcore - +.3V on mem. Can go higher but dont want any more memory voltage increase.

I guess it all depends on how lucky you are with the quality of the DDR2.

Conclussion: The first numbers are just theorethical and very conservative (Or another word I dont know)
 
Have you owned a recent e6xxx series zenmaster. Most of the results now a days at stock voltage achieving 3+ gigahertz, when using ddr 800 ram. A far cry from the 1.4+ volts I am seeing with the e4300 hitting 3ghz +.

Also there are a bunch of crappy overclocks with the e4300. Everyone doesn't get 3 ghz, even when using quality components.

To andrew, 3.0ghz is going to be very very hard on your system. Sorry if people like Taco and others have mislead you, but something like 3.0 ghz is not easy always as cake. Especialy if you have a bad overclocking motherboard.

Zenmaster the e6300 does not need expensive ddr2 1000 ram to hit those clocks. It can do fine with ddr2 800, which is not particularly that much more expensive than ddr 667(20 dollars). People pushing near 1.5 volts on stock cooling regardless of the frequency they reach are idiots that are listening to hype and bad reviews.
 
Might be a little early for this yet...but I am sure everyone wants to know what an E4300 can do, so here's the place to put it. :)

I am personally very interested not only in the highest OC you can do, but also the E4300's capabilities with NO Vcore Adjustments...seeing as the motherboard I am planning on has no Vcore adjustment (but it has everything else...go figure). So, if you can, please post both with and without Vcore adjustments.

Thanks!

Do a GOOGLE 😱

There would be a few tech sites that would have OC'd them.

3rd result in the list brings up this thread :)
 
Do you own a e4300 chip? Whats harder on the system an astronomical FSB or a vcore of <or=1.4? A 6300 needs an fsb of 429 to get to 3ghz!
Come back after your Northbridge flakes out. Compare that to the 333fsb of the e4300 that gets you to 3ghz (thats with 667mhz memory). Run the e4300 at the e6300 native 266mhz fsb and you have hit 2.4ghz (533mhz memory). Now I dont know what people are expecting from this chip. It was touted as an excellent budget overclocker and thats what it is. It was not touted as the end all be all of overclockers
 
Pax2all, I didn't say anything particularly bad about the e4300. I just said particularly that you guys are incorrect about the overclocking ability of the e6300. It very easily reaches 3.0 ghz and noone has comeback about fried northbridges yet( I would also like to note high fsb give better performance than low fsb). I still think a northbridge can take it more so than the chip because alot of people are saying that 3.0 ghz is the very limits that stock cooling can handle. A northbridge for the most part doesn't even need active cooling. If you have a modertately ventilated case it doesn't need it. Especially with p965, most people are rarely blaming their MB for a poor overclock for FSB, because so many are capable of near fsb500 range.

1.4 Voltages can be pretty rough on a stock cooler. But 1.45-1.5 is irresponsible. I seen some 1.55 volts which is going to fry most air units. All these newbies that are overclocking are doing things that will reduce the life of their CPU significantly.

You guys are promoting it as the end all be all overclocking. Not only for budget but for everthinng. THings that people are comboing these with I have see are tuniq towers, Peltier coolers and 8800 gtx and most have your" absurdly expensive" pc6400 ram. Hardly anything budget about that.
