Intel Core 2 Duo E2140/E2160 Overclocking Results

[Bobsama]

Well, I didn't do it directly but I was the primary source of information for the overclock.

Without further ado... I do bring you... Lew Blu's... E2180.

Processor: Intel Pentium Dual-Core E2180
CPU Cooler: Scythe Katana 2 with stock fan
Motherboard: Asrock 4CoreDual-SATA2
RAM: Kingston 1GB DDR2 667
Graphics Card: Geforce MX 4000 128MB
Hard Drive: Hitachi Deskstar 7K160 80GB (iirc) and Seagate (something-or-another)
OS: Micro$oft Windows XP w/o SPs install yet

So here are some results...
Maximum frequency (no stability tests yet): 2640MHz

SuperPi 1M - CPU-Z Dump
2.0GHz - dump
2.44GHz - dump
2.64GHz - dump

There ya go--any tips? I need some info on setting the timings for the RAM on the Asrock board--everything (except CAS) comes up as like 2T, 4T, 6T, &c. I'd like to loosen them up a little bit to see if it's still RAM limited or if it's board limited.

Thanks,
Bobsama (on behalf of Lew Blu)

Nice results here, my 2140 goes at 3.2GHz with 1.375V. Now 2 questions:
-what is the max core temp that i should watch for?(now its standing at 59-60degrees celsius with Orthos running)
-how much should i test it with Orthos to see that is really stable
-how much vcore can i pump into him?
Currently running on P35-DS3L from Gigabyte and 4x1Gb Teamgroup Xtreem Dark(DDR800,4-4-4-12 at 2-2.2V)

Lower the voltage on the RAM default voltage according to JEDEC DDR2 specifications is 1.8v. Runnning it at DDR800 with 2.2v just because its "rated" at 2.2v is idiotic. Not saying u are an idiot, just Ive been noticing alot of users happy to dial in the maximum Vdimm before even testing default speed at 1.8v. U might need a little extra due to 4 dimms and tighter timings but only raise it if u discover instability.

Test for 24hrs to see if its stable, bear in mind that what is stable in winter might not be stable in summer. I wouldnt put more than 1.45v through CPU with aircooling. Temperatures look good. I'd be tempted to leave it like that or test if u can overclock further without more voltage and hence higher temps.

I set the ram voltage higher then the 1.8 mark because it wasnt stable in Orthos(cpu&ram test failed but cpu test ran flawless) at over ddr800 and 5-5-5-15.
I will test with Orthos longer to see that its stable.
Now the ram is at 5-5-5-15 2x400 and 2V.
