Overclocking Intel E5300

[Driftmonkey]

So, I'm trying to overclock this CPU. Currently disabled speed step - have it set at 3.20ghz with 1:2 fsb : dram.


However - I have a couple of problems - when idle - multiplier keeps droppin to x6 instead of staying at x13.

Also - when I go to Prime95 test - it errors and stops straight away - could this be the 1:2 fsb : dram?

Mobo : ASUS P5KPL-AM/PS
CPU : E5300 @ 3.20ghz with Xilence Cooler
PSU : Two 350w Thermal master run together
RAM: DDR2 2GB

Found that it was failed ram. Will get some more in near future - however for now - will get some new thermal paste. Idle temp are 37 degrees. Multiplier also now locked at 13x 260

My fsb is at something like 960 (correct me if I'm wrong?). I'm guessing this is why my RAM failed, it was DDR2 800mhz...

Currently can't go past 3.27ghz. Not sure why... can anyone shed some light on this?

That sounds about right for that chip. I would throw the chip and put a Q6600 in then clock that. Your ram ratio is far too high. Your ram speed should be under 400x2. Alter the ratio untill it is under 800.
Do some reading before you start blowing things up, eh?
If the ram doesnt work now its probs because you have blown it.

 

[chrisso]

At 1;2 fsb /ram ratio, you have reached 800 meg ram max speed at stock cpu clocks.
Start overclocking with all the memory functions set on auto. I have one of those boards, it will do it all for you as you raise the bus. There is no cpu voltage control. You are near the max overclock.

What BIOS version are you on? I can see many CPU voltage controls..? Vcore - north bridge - south bridge.

I've also seen many people go way beyond 3.3ghz on these cpu's. What's bottlenecking me from going any further?

The frequency drop is caused by intel speedstep reducing the cpu multiplIer when the chip has no load.
It is to save electricity. In the bios it is called EIST; ' Enhanced Intel Speedstep Technology'.
You can choose on or off, it wont affect your performance at all.

 

[chrisso]

Dunno. Not using it as it has faulty ps2 ports and I struggled to get windows on it. I used it for a while.
It was really fast. I might give it a bash one day.

It was actually caused by an option named "C1E Support" which was dropping the multiplier to x6. I've always had speedstep disabled and disabling C1E support is what stopped the multiplier from dropping.

That chip is so weak it isnt worth the bother. You wont notice any difference between say 3.2 and 3.4 gig.
You have the lions share of free performance.

Yeah, this computer isn't important to me at all - hence the dual powersupply - excessive overclock with everything on auto. Got everything for free so it doesn't bother me (bar the new cooler).

Was hoping to get it faster than my only other computer (2.4ghz dual core laptop, onboard gpu). Which is pretty damn useless.

 

[chrisso]

The problem with instructions in bios is they are translated by chinese . They are often wrong and can vary.
At the least, they are unclear.

 

[chrisso]

If you put A Q6600 in that board it will make a good midrange games rig with say a gts 450 graphics card and will rip all over the laptop. Its worth doing. Only cost you about 75 £.

 

[Driftmonkey]

So, no idea on why it won't go past 3.27ghz specifically? Other than the obvious fact that ram is - bad.. lol.

It won't even post. If I put it to 250 , it will post - 251 - won't post - will have to turn off power supplies and then turn it on 10seconds later - it will be at 2.61ghz again.

 

[chrisso]

You can run 3 gig of ram as well. The bios will even run it in assymetric bank interleave.
It will go like snot. I know. I tried with an E6600 and it was fast.

Problem is - as I said before. I have no cares for this computer - therefore no want/need to spend money on it. Using what I've got - again - hence the dual psu.

Only going to be buying a gpu and ram - that will most likely be it for this computer.

Will overclock it to 3.8ghz when I have ram then will call it done.

Run 1 psu, you dont need 2 to clock without a graphics card, esp with vcore control. Its only a low level twin core. Start again. If the ram is no good wait untill you get more. Seriously, dont mess that bored up, its a good cheap games funbox waiting to happen. You will need to lock the pci-e bus at 100 meg. Just dont mess it up yet.

 

[chrisso]

Well, do that then. You can wait for a gift cpu, theres a lot about.

Yep, and I understand that - especially as it came from a friend as he was about to throw it out the window lol. I've wired the two psu to run in line - can't pull them apart. Yep - ram is definitely bad - tested with ram tester and it error'd straight away.

Will wait around for a cheaper Q6600 to come up and will most likely grab that. 1066mhz ram and gpu will be first however.

Funny - dropped DRAM frequency to 667mhz instead of auto and now everything works completely fine - running ram test and it hasn't found any errors as of yet. Interesting.
