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

P5B Deluxe & e2140


Cannot for the life of me get over 300FSB stable on the above combination? The motherboard refuse to boot :confused: My AW9D Max took this chip to 3.0GHz stable.


Any body have any ideas? :)

Cob's right. It looks like the problem is with your RAM.

Set the divider to 1:1, make sure you've set the correct voltage for your RAM and if you've got 4 sticks then up the NB voltage to 1.4v.

Set your 'FSB strap to NB' to 333 as well cos Asus boards prefer this.

Let us know how you get on.
 
I'm setting up my E2160, and I was wondering something.

450mhz x7 = 3.15Ghz
400mhz x8 = 3.2Ghz

Which would offer more perfomance, 500mhz more on the cpu, or 50mhz on the ram and cpu?

Or would it be totally negligible?

I was adviced to go for more CPU rather than bandwith. But i think the 50MHz not gonna make much diff anyway. If your ram can take 900 than maybe i'd go for that. Actualy may try myself tonight and run 3dmark and see if it beats my 12800ish.

As long as your cpu will do an fsb that high then that's what I'd go for. Why not 455x7?

Not all E200 series chip will run an fsb that high though. Mine won't do over 380! :(
 
OK, I've got a E2140 and I'd like to get some more speed out of it. Where exactly do I start? Just start upping the FSB and see where I get?

I have a GA P35C DS3R Mobo and 2 x 2gb PC6400 OCZ Gold memory. Thanks. :)
 
Thanks mate. ;)

Ok. Turns out I have a E2160 (cant remember ordering that!), which is 1.8ghz.

I'm up to 2.2ghz on all stock but DDR2 voltage +0.1. That's 245mhz x 9.

Do I now start lowering the multiplier and upping the FSB? Or upping the voltages?
 
Ok, seems I'm just babbling to myself here, but I think I actually udnerstand what I'm doing now.

Up to 2.7ghz stock voltages on everything. How much past the RAM speed of 800mhz will I ultimately be able to go? Is that purely dependent on the quality of RAM?
 
Thanks for the tip guys! :D


Got it to boot at 375 due to setting the memory 1:1 upping the NB and FSB voltage also upping the memory voltage to 2v :)
 
This is weird. I'm on 390 x 8, 3120mhz, not necessarily stable, but it wouldn't boot up on 6,6,6 timings but did on 5,5,5. What's that all about?!

I might try upping the memory voltage as yuou are doing fothsn as otherwise I won't be going any further than this. :(
 
I'm giving up mate. I've a 2160 (thought it was a 2140 but apparently not) and going to stay at 375 x 8 for 3ghz with tight memory. If that's stable then that's good enough for me - that's a solid 60% increase on a £50 chip.

Not sure what it would be though that's keeping me back TBH though. FSB is not even at 400 when it dies, and the voltages are fairly high. Maybe that's just the way it is? :confused:
 
I mean, look at this. I know it's not strictly indicative of true performance, but here's the two setups.

Despiute what it says, the first is 390x8, the second 375x8.

What are safe voltages for these babies?

I am on the following...



It's reporting it wrong - it's a clocl multiplier of 8 giving 3.04 ghz. WOnder why that is?

Speedstep. Intel's method of reducing processing output when the machine is pretty much idle is to reduce the multiplier to the lowest value - in this case 6. Disable it while you are overclocking and reenable it once you are done. It's pretty useful in helping you keep the temps low when not doing anything heavy.

I reckon you can go further than 3Ghz. I'm up to 3.15 on an L2 revision. You should be able to get to 3.2 on a M0.

You've proven that you can hit 380FSB. My wall is 371. What's your cooler?

Try this:

355 * 9
Speedstep off. It's not on the MIT screen, and it's called CIE or something (sorry, doing this off the top of my head).
are under 70C load.
mch +0.2
fsb +0.2
vdimm 2.1 (I think that's +0.3)
divider 2 (1:1)
RAM 5,5,5,15
then up the vcore starting at 1.425 through to 1.50 in .125 steps.
