***The Official E4300 Overclocking Thread***

Well I got my build finished last night. Really pleased that everything worked out first time, no problems. I had a few things to do last night so resisted the urge to do any overclocking. Couldn't resist it this morning though since I had a late start, did a little experimentation and left it running a few tests. I tried some various settings but settled on this (from memory):

Vcore 1.425 (but will be trying to knock down if this is stable)
FSB 333
VDimm 2.2 (default for Crucial Ballistix)
RAM x2 (effective 1:1) running at 666mhz (which is below its stock 800)
Fsb overvoltage +0.10
MCH overvoltage +0.10
Tigthened the RAM timings to 4-4-4-12

An effective overclock to 3.0 Ghz which to be honest i'll be happy with (might push it further depending on stability.

Things looked ok when I left for work. Orthos had been running for 30mins without a problem. Temps were upto 59C on both cores, I think they idle at 36C but i'll confirm that. No images yet (should be able to tonight though).

Three Questions:
1. Notice anything that might need minor adjustments, anything i've missed?
2. Are temps at 59C anything to worry about (using Noctua NH-U12F)
3. What should my max temps be before I stop?

Thats a good overclock! The temps are really low too!

Cheer's. :D It was bloody freezing up here then and with the rad in the window and the window open it makes for excellent cooling. I ran Orthos this afternoon to see what temps i am getting at full load now that the weather has turned quite hot, and it still only tops out at 45 degrees. Very happy with that. :D :D
 
Ok ran a 8hr Orthos overnight to test the below setup, an effective overclock to 3.0 Ghz ... no problems so far :p

Vcore 1.425 (but will be trying to knock down if this is stable)
FSB 333
VDimm 2.2 (default for Crucial Ballistix)
RAM x2 (effective 1:1) running at 666mhz (which is below its stock 800)
Fsb overvoltage +0.10
MCH overvoltage +0.10
Tigthened the RAM timings to 4-4-4-12

How the temps look? 32C idle 62C under full load (using Noctua NH-U12F)?

I was thinking of trying a 400x8 to get more out of the RAM. Is thay going to be possible?

Just increase the ram multiplier to make it run faster. It should be ok at 2.50.
 
Thought about that, that WAS going to be my next question :)

What about the temps? They look ok? What's the absolute limit I should be allowing the temp of the CPU to reach?
 
Temps should be fine for air cooling. Not sure what the max is for these. I ran my ram at the 2.50 multiplier when i was at 3ghz, and it's only a slight overclock of 832.5mhz. You should be able to drop the Vcore down to at least 1.4v. Mine would do 3ghz at 1.375v but now it can go down to 1.35v.
 
I haven't had time to do much experimenting, had a lot of work on, so that overclock there is just a first attempt going off other peoples efforts and reading threads. When i have time i'll play with voltages and fine tune it a little more... though it is a little bit too tempting at times :)

I'll knock the RAM up to 2.5 and leave it at that for now. My target is 3.2 from the CPU but I think that will have to wait a day or 2. :rolleyes:
 
It is tempting to play around. So much so that you don't get to use the pc for what it was put together for. Especially when it boots at 3.6ghz. Can't be bothered to run Orthos for 8 hours to test for stability so i have settled at my 3.4ghz clock. I am very happy at that anyway.

My first clock was 3ghz. I just took the settings from the DS3 thread and crossed my fingers. Booted first time no problem. Next was 3.2ghz and eventually 3.4ghz. Easiest clocking rig i have ever had. The 4300 was meant to be a stop gap until the price cuts came in but i am not so sure i want to swap out a good clocker like this for something that may not be a good clocker. A 6600 at £137.99 elsewhere is very tempting though. :D :D
 
Guys i need help :p no really

When I set my FSB QDR to 1300 which sets the FSB to 3Ghz and I have it as 1:1 with my ram I can boot my machine. I have to clear Cimos to get it booting again :confused:

When I set it a 1:1 with my ram the ram also clocks to FSB QDR 1300.

I got in my options

1:1
3:2
5:?
Sync Mode

Someone help plz
 
:eek:

I'm surprised it even booted the first time as it would have been running DDR2 1300!!

The RAM options are strange on the Nvidia 680 / 650:

SYNC - actually 1:1 RAM:FSB
1:1 - actually 2:1 RAM:FSB

Try running it in SYNC mode.

You are highly likely to get "FSB Holes" where you think you've pushed it too far but pushing a bit further or adjusting your voltages will suddenly get it booting again.

I'm having similar problems - can't push my E4300 much over 2.3GHz. I'm sure I'm missing something obvious - and I'm not looking for an uber-overclock! - but I'm sure I should be able to get a little bit more than this...

I'm running the latest/most stable version of the BIOS (1002) for the Asus P5N32-E motherboard. I'm currently got the FSB at 1048 (262), so the CPU is at c.2358MHz, and according to CPU-Z the memory (OCZ 2 x 1GB PC2-8500 SLI DDR2) is running at c.419 MHz (FSB : DRAM 5:8) 5 - 6 - 6 - 16 - 24 - 1T (1T forced in BIOS, other settings left for the moment to AUTO). I've left some of the voltages on AUTO; the exceptions are Memory Voltage (2.250V), 1.2V HT (1.30V), NB Core (1.40V) and CPU VTT (1.40V - it didn't seem to like 1.50V in the slightest).

The CPU's cooled by an Arctic Cooling Freezer 7 Pro, there's a Corsair HX 620W to provide the juice, an 8800 GTS to let me play games, and it's all housed in a very cool Lian-Li PC-60 Plus, so temperatures don't appear to be an issue (I've never seen the CPU hit 50 degrees, and it rarely comes above 40). Oh, and I'm running Vista 32-bit, but I don't even get that far when I try to bump up the FSB/CPU a bit.

I'm sure it's blindingly obvious, so go easy on me, but if anyone can think of something obvious, I'd be delighted. I was hoping to get the CPU running at somewhere between 2.5 and 2.8GHz - or was I being unrealistic?

Many thanks.

try putting the ram 1:1 as it should be able to handle that fine.

I did but its clocks it big time with the CPU, so the Ram will run at 3Ghz lol

I think i will try Sync Mode and see what happens

My FSB hole was between 1200 - 1300, I set the fsb to boot straight at 1333Mhz and it posted at 3Ghz :)

If you can't get it past 1046Mhz try 1150 or 1200 and see if it works.

Thanks. I changed to a 3:2 FSB : memory ratio, fiddled with a couple more voltage settings, and dialled in 1200 - and it booted, and is running fine (2.7GHz CPU, memory at 400 MHz, 5 - 5 - 5 -15 - 22 1T). (FWIW, this pushes both my CPU and memory scores in Vista to 5.9.)

I've tried 1230 - boots but crashes in Vista - and 1240 - which boots, but does not get as far as Vista. 1250 and the thing won't even switch on! So I've either reached the outer limits of this particular chip, or am stuck in another 'hole'. But, for the moment, I'm quite happy with a £80 chip that now runs at the sort of speed a £200 E6700 achieves at stock...

Thanks for your help!
