***The Official E4300 Overclocking Thread***

I got my E4300 and an Asus P5B today.

I'm using the stock heatsink as I can't find the LGA-755 mounting brackets for my Scythe Ninja, I'll have another look over the weekend.

Currently got it sitting at 3GHz, I increased the vcore to 1.4v in the bios as it was falling over at 1.325v but it's drooping down to 1.36v under load, so can afford to wack up the voltage a bit further later on.
 
Well, I'm kinda bored of this now... it seems to work fine at 3.4GHz, I'm happy with that. Doesn't seem much point going after the last 100MHz or so.

with all these overclocks has the FSB voltage been increased ??

or is that voltage left at stock ?

In most cases the voltages are significantly above stock. FSB Voltage is specific only to a few motherboards, so you'd need to get that info from those users. I don't touch it on DS4's.

I'm stable 3.2GHz, gotta keep the pace though, next stop 3.4GHz stable. :D

That's not Dual-Prime/Orthos Stable? That app is testing only one core? I can run that test at 3.6GHz but as soon as you start testing both cores at the same time it fails . . .

I can run 2 copies of SP2004 stably, but the new two core beta version fails for me too. I'm not entirely certain that it's completely stable itself. Not only that, but it tends to fall over rather than stop cleanly.

Is there anything else we could use for stability testing? It seems a bit carp that I can run F@H 24/7 and play games and just generally mooch about the internet without problems, but I can't claim the overclock is stable because Orthos fails after 20 minutes.

Yup, not Orthos'in with the BETA version. Ran the old version for 4 hours. Typical. :D

What memory do you guys have and what do you have it running at, timings, etc?

Yeah there is something funny going on with Orthos, If I start it and stop it again quickly it hangs?

There are other options, you can run two instances of SP2004/GO thingy (two different folders) or run proper 'Dual-Prime'

  • Install Prime95 (once)
  • Copy shortcut and ammend the path with -A0 and -A1
  • Open both shortcuts and set CPU affinity (Core0 on first and Core1 on second)
  • Start Dual Priming

The only disadvantage of this method is there is no obvious way to keep track of how long the test has been running, so flick open Windows Task Manager, click on the Processes tab, then [VIEW] >> [Select Columns] and put a tick in the [v]CPU Time checkbox.

Do you guys run with a +.1 offset, or do you just add the extra .1 to your vcore in the BIOS?

Ended up happy with the following results stable, each with a few hours of blend, small and large FFT's to their name.

Just installed a T'right SI-120 cooler and when AS5 settles, i'll try again with 1.6v and see if it'll let me stabilise 3.4GHz. :p
-----------------------------------------------
350x9=3.15GHz, 1.425v, 2.2vDIMM, 1.5NB, 450(900DDR), 4-4-4-10 - 18.047 SPi 1MB, 75C load temp
(notes: reduced to 63C load with new cooler)

360x9=3.24GHz, 1.5v (+.1 offset), 2.2vDIMM, 1.5NB, 440(880DDR), 4-4-4-10 - 17.906 SPi 1MB, 80C load temp
(notes: won't do 900DDR with highest vDIMM)

375x9=3.375GHz, 1.55v, 2.2vDIMM, 1.5NB, 400(800DDR), 4-4-4-10 - 17.328 SPi 1MB, 85C load temp
(notes: need to test higher memory freq, as Pi scores are worse than at 3.24GHz, temps not tested with SI-120 either)
-----------------------------------------------

As you can see, the climb from 3.15GHz to 3.24GHz and a 0.75volts difference for just over 100MHz is just not worth it at all.

At 3.15GHz and a max load of 63C with my trusty SI-120 however, i'm sitting pretty with plenty of speed with a 75% overclock over stock.

I can probably get to 1.6v with the SI-120 (albeit at an estimate of 75-80C) and try for 3.4GHz, but it wouldn't be feasible over a lengthened period due to temps and the obvious amount of volts i'll need for under 200MHz more.

So yeah, that about covers me, time to start using this machine for what it was built for; pr0n and games. :D

Please help a noob.

Hello everyone.

I'm trying to overclock my E4300, but I'm having trouble finding the right combination of settings to get it stable. At this very moment in time, I've overclocked it slightly, to about 2.6GHz (vCore 1.352, NB vCore 1.55v, Memory Voltage 2.15v). I've not yet tested this configuration using Orthos. However, my CPU speed is constatntly fluctuating, when idle, between 1.74GHz and 2.61GHz. So I'm not sure what the true speed of the CPU is. Also, the multiplier fluctuates between 6 and 9; 6 when at 1.74GHz and 9 when at 2.61GHz. This is all based on CPU-Z. But this is beside the point.
I've heard that the E4300 can be easily overclocked to 3.4Ghz using the stock cooler. I would like to do this, but have little idea of how.

My setup is:
Intel E4300 CPU with stock cooler,
ASUS P5B-E PLUS Motherboard,
2x1GB PC6400C5 800MHz 5-5-5-15 Geil RAM.

I know that my motherboard can be considerably overlcocked also, but I'm not sure if I need to overclock the motherboard in order to get the CPU to 3.4GHz.

Any help at all would be very much appreciated, as I'm a bit of noob in overclocking.

Thanks,
Fraser.
 
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

On a side note, I just passed 10,000MB read with my memory without breaking 3.4GHz! Hooray! :D



Unfortunately i'm hitting 80C temps load, so i'm gonna have to wait till my SI-120 bracket comes for the P5N-E, so I can test stability further at 3.4GHz with better cooling.

80*C :eek: good thing intel chips are built like bricks then :p
