im currently on 2.7ghz and its stable volts 1.5... HTT 4x multi 11x think im gonna try for 2.8 later

A64 SD 3700 @ 3080 mhz 280x11 @ 1.52v last November.
-19 to -21 deg idling. Got to around 5 deg under load when stress testing.
Did have the stepping written down somewhere but cannot find it.
This CPU is going on the bay once my Opty 170 arrives

Wow YooEnt, nice speeds there. According to CPU-Z it says you have the E4 stepping... from what I've heard these are the best clockers.

It's done me good. Have tried to get it to 3.2ghz but I think the mem controller is flaking out at that speed.
May try for 3.2 again before I get shot of it.
Of course that's under an evap head.

Not really, Saturday evening I went out to eat with my family and sunday I went to see Ajax pummel RBC 6-0 and going to the pub afterwards so sunday evening was spent being drunk and now I'm back at work.TiZoR said:
First I have to look for a good stable DFI BIOS that is better than the one I currently have.

Finally some success, I might be rambling a bit but here goes.
I had all kinds of instability until I figured I need to run at the default 11x multi, anything else is unstable, also I can't run a memory divider so that has to be 1:1 I also found that the tRAS needs to be 10, the only memory settings I changed are 2.5-2-2-10-1T and the rest is on auto, not even tweaked yet
Knowing that I concentrated on seeing how fast my memory would run and so far I got to 260Mhz [email protected]
The CPU is running at [email protected] this might be a bit too much but I want to see if it is Prime95 stable, so far it's been running a couple of minutes on small FFT's stable, load temperature is ~37C with watercooling.
Bummer, Prime95 failed after 4 minutes, looks like I need to lower it to 11x250Mhz (2750Mhz) and test some more, I'll be right back
These are the voltages my CPU needs to be Prime95 stable: (for now, further testing required)
2200Mhz = stock 1.35V
2400Mhz = 1.35V
2500Mhz = 1.45V (not 100% sure, might be stable with 1.40V)
2750Mhz = 1.50V (25 minutes Small FFT's, 15 minutes Blend)
2860Mhz = >1.625V
failed after 4 minutes in Prime95 small FFT's)
Tomorrow I will see how fast I can run with 1.60V, looks like it will be ~2800Mhz

Hmm,
I got 2900 Mhz out of my cpu the other day..
But it was with 1.6 Volts.. Which i didnt like to do,, so in the end i dropped it back down to 2805 Mhz..
These chips realy do seem great value
Mine has been game stable on counter strike source for months.
Realy Great chip IMO CAB2E BTW

hi all
i have just purchased this chip (retail) and the X1800XT....
cant wait to get it all sorted and to overclock....
i am a complete noob when it comes to this so could someone point in the right direction in how to go about it....
i also have bought the MSI RD480 neo 2 along with 2GIG geil value ram....
only want a basic upgrade and will not want to really push it....
cheers
