Post your X2 overclocks inside!

[nOx34]

I havent been on this site in awhile but I figured I would post my 3800 X2 OC. I am at 2.95ghz at 1.58v on a TT Big Typhoon. Here is a SS. I am waiting on a Mach1 this week or at least by Tuesday.

Stop making me wanna remove my IHS man !

Impressive.

The X2 processors are awesome because of their low default vcore. I plan to buy a 4400+ by October, and OC it to 2.75 GHz, in par with a second 7800 GTX in SLI & a second Raptor for RAID 0. My PSU & Watercooling are ready to handle them

Are you guys that are over 250FSB running at 3xHTT or 4xHTT?

I always run 3x on anything over HTT-250. I have never seen a performance difference.

I don't care for overclocking but I will do it if I don't have to raise my voltages

Wow, your chip can handle 5x 216FSB? Mine was having problems at that,

Have it pretty stable at 10x255 with 3 HTT. Gonna try and see what I have to give up to get it back over to 4, but 2.55Ghz is about my limit. (My shuttle XPC is no watercooling setup, after all.)

But still, 2.55 Ghz I am quite happy with, espically seeing as how its at 4600 levels?, and in a SFF.

My memory is just not up to the job. Had to back it down to 166 to start (hence the low scores), but the proc is more than up for the chore.
This is pretty much the highest stable OC on this little shuttle. If I had a mobo with more VCore and VMem, I know it could do lots more.

Older version of CPUZ...didn't detect the correct core

I just got my 3800+... so far I'm 100% stable at 2.6ghz w/1.375v on the stock cooler and my ram is at 1:1 w/2.85v 2.5,7,4,4.

And why don't you like some more voltage? If you use a nice watercooler, temperature will be fine and so will the noise. And your PSU can hadle it comfortably.

I'm sitting at 2.5Ghz stable on stock voltage on a 4400+. Stock heatsink on it. Waiting to push more vcore until I get my new watercooling. It's booted up to 2.8Ghz with vcore bumps, but
I decided not to mess with vcore until I can keep it cooler. On the bright side, I ran my memory up to see how it did, I got to 330Mhz and stopped trying, though it errored with those timings at 350Mhz. I figure I won't run it at 330Mhz anyway.

Here are some of mine. i have had this 4200 for some time, but have a 3800 Manchester to try in a few days when i get the time.



This wasn't very stable, but shows what's possible:

At last a report of how Toledo cores overclock. I'm surprised to see little interest in these cores; maybe its the price. Is 2.5 GHz where it tops at stock vcore? Or is it that you decided not to push any further anyway, due to aircooling?

Oh, and by the way, do these CPUs have the overclocking problems that 130nm Athlon 64 cores had? Meaning that increasing their vcore barely made any difference.

[Astaroth125]

I think I'm limited by cooling at this point. It definately scales well with voltage with the limited testing I've done. My theory is that you need to keep load temps below 45-50'C to get effective overclocks. I'm hoping to get it stable at 2.55-2.6Ghz on stock vCore, and 2.8 stable around 1.5-1.55 vCore on water.

I think cooling, mobo type and Psu are going to be important to get the best out of an X2 chip, the Manchester is rated at 89w the Toledo at 110w, after replacing a 3500 Venice with an X2 3800 and running it up to a similar overclock I noticed the Pwm temp around the same as Cpu load temp, with the Venice it was 4-5c cooler, with both chips:

3500 Venice @ 2600 1.525Vore
X2 3800 @ 2600 1.45Vcore

Overclocked the same, the lower Vcore on the X2 means one thing, higher current draw, stock settings have the X2 with lower Vcore but higher heat output (89w) so with power (watts) being a simple P = E x I if you lower the vcore and the watts go up then there has to be more current draw, add the 110w Toledo to that list and the mobo mosfets and power regulation components are taxed far more than with a single Cpu, the extra drain on the 12v rail will find out any weakness in a "boderline" Psu, and all that extra heat has to go somewhere, so optimum cooling will be needed for serious overclocking,
I've had no trouble getting my X2 Manchester 3800 to 2.6g but I already had a good watercooled rig and a new dual 12v rail Enermax Psu, I think pushing to 2.7g is, for me not worth the extra heat and Vcore needed, I've had it Prime stable at 2700 with 1.6v vcore and while the watercooling copes well, it's still spring here, factoring in midsummer room temps I would be pushing the self imposed limit of 50c for overclocking, and worse, at that speed Pwm temps read 2-3c higher that loaded Cpu temps, even though I have the stock Cpu fan fitted directly over the mosfets.
So with the system at it's limit 2.7g Prime and gaming stable,
At 2.6g it's still a fast dual Cpu rig, a cool and only moderately stressed system that I can run 24/7 in the hottest of summers,
While the 1 meg cache per Cpu Toledo will undoubtebly perform certain tasks faster than a Manchester would, overclocking it to the max will need high end cooling or low ambient temps, and top notch mobo and Psu.
