***The Official E2140/E2160 Overclocking Thread***

Hey all.

Got myself a 2140 for an HTPC build with 2gigs of the 6400 geil low latency ram on offer. Its all been put in an Antec Fusion V2 Black with 2x 500 gig aaks WD drives. Im using the F190HD Abit board due to the HDMI port.

Im mucking about with the FSB and reading reports it tops out at 350 ish. I can only seem to get 320ish out of it at the moment.

I have the ram timings at 4.4.4.12 and bumped up the voltages all across the board a little bit. It seems stable at 2.6ghz which isnt quite good enough for my movie files I will be playing (1080p) and judders slightly, enough to annoy me. I am using a retail heatsink.

Does anyone have an idea as to what I can do to make it play ball? Another heatsink is certainly an option but I am also thinking perhaps changing the CPU for one with a slightly higher multiplier. My desktop (e6600) at stock struggled too - thats now running perfectly at 3.3ghz and is ample for 1080p.

That is unless one of the boffins here knows something I dont? (highly likely). Surely the e2140 and an F190 is a popular choice here?
 
this is where i'm at with my E2180...

52 degrees after 12 hours stress testing seems good to me. although it was 55 degrees after only an hour.

I'm dead chuffed with this cpu!

Doomy, sure it isn't a graphics card problem rather than a processor speed issue ?
Playing video's (even high res ones) isn't all that stressfull on the cpu.
Checked its not a graphics card issue ?

And nice duvet, now get it to 3.4 :)
The red"paging" is always irritating, makes me think its failed.

wow nice, what cooling do you use for that?

That's Vapo LS :)

I was trying to get max stable FSB; 475x6 or 465x8 seems to be the limit at 1.5v vcore in the BIOS (I have a 32m screenie at 465x8, got pretty good stability there). The overclock was about the RAM as much as the CPU, CellShock DDR3-1800 8-7-6-21 running at DDR3-1860 7-6-5-18, 1.9v. Really, really nice sticks. Want to get 500 FSB and DDR3-2000, need to try my Q6600.

No suicide there - I was using it like that for an hour or two no probs. It's happy with a dozen ordinary apps open, haven't tried Orthos or UT3 yet though.

Edit: 10 minutes of Orthos before it keeled, but I was browsing in Firefox at the time to relieve the boredom lol.

E2180 M0 bought from OcUK at about mid day 27/10/07

Asus Blitz Formula

Small two stage r404a/ethylene cascade

1.8v core, voltage doesn't help that much, 1.9v made no difference, it's FSB limited :(

~10 miles from OcUK:

Posts up to about 475MHz but keels over loading Windows instantly. I think we have a WPrime at 4550MHz, not entirely sure, we definately have a CPU-z verified. Pretty good chip for £55, would have been nice to suicide 5GHz but can't grumble :)

If i can get a big cascade on it we might be able to run 4700MHz but at the end of the day the packaging substrate on the E4000 series just wasn't meant to run at high frequencies...

It was pretty stable at that speed, didn't try 3DMark tho. Could have probably got off a 2001 run at 4550MHz, would have definately passed at 4500MHz...

What is your Vcore setting for that speed, I know what Speedfan and CPU-z are reporting but I'll assume that they aren't right..?

Very impressive clock there with that £60, or less, CPU :)

vcore is set at 1.325 in bios IIRC. i'm led to believe that cpu-z reports the actual voltage being supplied to the cpu because of motherboard vdroop/vdrop... i forget the difference between the two... i'm new to this sort of stuff.

i'm going for 4.5GHZ next!!! :D

4.5ghz.......thats mental. what temperatures was it getting too ?

You said that about a 3.2ghz but not the 4.5ghz ? lol

Yeah because for us mere mortals that can only afford a cheapo cooling system I know that 3.2 can be achieved on air :D

That doesn't mean that 4.5 isn't impressive, it is, but just not achievable for me.

That really is impressive with such a low Vcore :)

Well done, don't stop until it melts :D
 
vdrop is the difference between whats set in bios and is reported in the OS idle.
vdroop is the difference between whats reported in the OS at idle and what it drops too under load.

IIRC anyhow. Id say 3.2 is to almost be expected on E2160 +, sure you can atleast manage that :p
My E2140 is @ 3.2ghz stable atm, cant seem to handle over 400mhz fsb tho.
 
I agree in that it does seem to be often reported that the E21x0 is running at 3Ghz or above but I must admit it does still amaze me at the performance of these CPU's against the cost. I'm not sure though how common it is to hit 3.2 at such a low Vcore..?
