Bit of overclocking help please....

Hi all I recently got myself a new pc which consists of the following:

E2160 @ 3.0Ghz 340FSB 1.4v
Tuniq Tower 120 CPU Cooler with Artic Silver
4x1GB Crucial Ballistix PC5300 @ 3-3-3-12 667Mhz 2.2v (trying for 4-4-4-12)
Gigabyte GA_P35C_DS3R
Radeon 2900XT
P182 Case
500GB HDD

Now as you can see Ive overclocked a fare bit

Now I can get it running stable with the memory at stock (3-3-3-12 667mhz 2.2v) but with the slightest increase it blue screens. Now i had a little look around in the case and the memory was absolutely roasting :eek:

I take it this is what is my problem. My CPU runs at 60oc at the very most

Another question is that as soon as a stick the CPU up to 3.1Ghz 1.425v I get this in orthos:

1:Test 1, 560000 Lucas-Lehmer iterations of M212991 using 10K FFT length.
1:FATAL ERROR: Rounding was 0.5, expected less than 0.4
1:Hardware failure detected, consult stress.txt file.
1:Torture Test ran 16 minutes 55 seconds - 1 errors, 0 warnings.

I have not stress.txt to view either. Anyone shed any light on this?

Will see how they perform then

3 GHz is the max for a E2140...u wont get 1MHz more.

E2160 max is 3.6GHz. The chips are FSB limited

Its a E2160 running at 340 x9.0 it gives me 3.0ghz and in CPU-Z it shows that the rated FSB is 1380mhz but im sure my board only supports 1333 :confused:

That's the advertised max. They'll do well over 2000mhz.

Excellent news

e2140/e2160 are FSB limited @ 400MHz. E2140 will reach 3GHz (more than likely) and E2160 will reach 3600MHz (more than likely).

What sort of Vcore will i need for 400 FSB ive tryed 1.475 and it wont boot. Thats 400x8 with the ram divide on 2.0 gives 800mhz 4-4-4-12. Just resets the bios to default

Also just tryed 400x8 1.525 and nothing

Eh? I've never heard anything about E2140/2160 being FSB limited to 400Mhz. I think plenty of people have clocked them above that. And the latest Gigabyte boards are pretty good - my DS3 does 460MHz FSB solid as a rock, and some people have hit 500.

Mine seems to be fine at 399 FBS then as soon as a stick it to 400+ it wont boot at all :S
