Hello, this is my first post in this forum, so I was expecting someone could help me...

At the moment im stuck at overclocking my AMD Athlon 64 X2 5000+ Brisbane (2.6Ghz, 1MB L2 cache, 200X13)

This is my rig:
NZXT Tempest case
Asus Crosshair II Formula Motherboard (780a SLI)
AMD Athlon 64 X2 5000+ Brisbane
Gigabyte 9400GT 1GB DDR2
500GB Seagate Barracuda 7200RPM
CoolerMaster GeminII cooler w/ two 120mm LED fans from Coolermaster
Trust 420w PSU
4GB DDR2 800Mhz Kingston

Here is where I am: At the moment it's runnig at 3167Mhz (264X12). If i set it to an x1 multiplier it won't boot. Because this is an extreme mobo, it sets the voltages autommaticaly and thats what scares me. Default voltage is 1.344v and on auto it sets it at 1.6320v :eek: . At idle its sitting at 45ºC and on load it goes as far as 67ºC, so that leaves me thinking that I haven't installed the cpu cooler correctly... I'm using Artic Silver MX-2 thermal paste.

1st: Is this overclock high enough or should i go for some more mhz? I want to squeeze every little inch of performance i can
2nd: Do you think 1.6320v is too much?
3rd: Do I have to reseat the cooler or replace it, because i don't think 67ºC on load is normal, even with 1.6320v...
4th: Would i benefit of switching the two fans on my cooler and putting more powerful ones?
I don't think its lack of airflow because my case has 6 fans on it (that's why its called the airflow king)

Thank you for your time

(Sorry for any spelling mistakes, I'm from Portugal.)

I have a mobo that also sets the cpu voltages automatically as well.

Do you have the "over voltage" option on the mobo? Manually setting the over-voltage instead of letting it be on auto should help you reduce the voltage.

AMD cpus do run on higher voltages than Intel's cpu...but 1.632v is way too much. I think the stock voltage for Brisbanes go up to 1.4v...

Thank you very much for your fast reply.
I decided to set the voltage myself. I won't go further than 1.6v
Note that my 5000+ is the retail version so i can't raise the multiplier.
I have to reseat the cooler because my cpu shuts down at 72ºC. I'm going for the 3.3Ghz mark.
I've also read that mobos that have nvidia chipsets wont overclock very well... Is that true? Because I'm very happy with my mobo. Its very stable, so i have to asume that its just a myth...
Anyway I'm gonna reseat the cooler and then I'll post the results.

Thank you

1.) The Athlon 64 X2s are not big overclockers, at best you'll get 2.8 GHz - 3.1 GHz stable, on the black editions or on the Kuma version you might get around 3.3 GHz if you are lucky. If you can achieve " 3167Mhz" on an Athlon 64 X2 then consider yourself lucky because most overclocks are a lot lower.

2.) Yes 1.6320v is way too high. 1.5v is the highest you should exceed.

3.) It has nothing to do with your cooler, if you put 1.6320v through the CPU the temperature will rise, you might even end up with a burnt out CPU eventually.

4.) No point switching fans, wasting your time. Your overclock limitation is not because of heat, its because the Athlon 64 X2s are not great overclocks

If you are unhappy with your Athlon 64 X2 5000+ replace it with a newer processor, the Athlon II X3/X4 or Phenom II X3/X4 are newer and much faster.

PS. If you are a gamer the 9400 GT isn’t a good video card.

Thank you very much!
I already knew that someone would talk about my 9400GT that's why I put it there. It actually plays almost anything (except crysis obviously). at 30fps 1280X1024. But I'm replacing it with a GTX 275.

About the cpu, i'm going to buy a 955 since they are really cheap now and they're really fast.

Thank you

personally I would bring it down to around 2.9 ghz and as said put the voltage down to 1.45 , otherwise it'll fry not fly

Thank you very much for your suggestions. I'll try them out, though i've managed to put it working at 3.2 at 1.5v.
Because of my motherboard, I'll have to stick with nvidia, since it has an 780a chip. But the 5000 series from ATI may give nvidia a run for its money and price drops. I appreciate your opinions!

:non:

That is a myth, Nvidia chipsets run fine with ATI video cards. Likewise ATI chipsets work fine with ATI video cards.

I have mixed and matched plenty of times, 780a chip supports PCI 16x so the 4000/5000 series will work fine.

Just make sure you uninstall your Nvidia's 9400 GTs drivers before putting in the ATI card, and you'll be fine :)

Yes i know that one ATI card will run perfectly in an nvidia chip, and i'm just saying that i won't be able to run crossfire in this motherboard, and it would a waste... Maybe i'll buy my brother a crossfire mobo and we'l compare benchmarks.

Well, this motherboard has 3 way SLI so i was hoping i could get a good kit for a good price, like i was hoping to get two GTX 275 so i wouldn't need to change anything in a couple of years.

BTW, when i set my vcore to 1.45v it shows up as 1.44. Why? Is this because of my psu? Because i have to set to 1.52v to get 1.5v...

Ah, i see. But what if i hold on to this 9400GT (i don't mind) and buy a GTX300 when they come out. I think they'll be released this Christmas... so its only about one month. What do you think?

But i'd rather stick with nvidia since this mobo supports SLI... Because instead of selling and buying another video card, it's much more easy to simply add another one...

I've been reading reviews about the GTS 250 in SLI, and it seems that 2 GTS250>GTX285... So, do you think its a good option? They also only need one 6-pin power connector. Also, all that i'm missing is the psu. Which one should i pick? I want one that supports SLI. What do you think of the NOX Apex 600w?

In my country, two GTS 250 are WAY cheaper than one 285. And one 955 costs 160 euros (240,783 dollars) and one gts 250 costs about 180,58691 dollars. Well, i'm gonna stick with the OCZ ModXstream pro 600w. Do you think it will handle two gts 250?
Thank you for your support :)

Well, the 720 costs 120. Is it worth the difference? I'ts a black edition so I can play with it.

The Athlon II X4 620: 92,90€ (139,82541 dollars)
Athlon II X4 630: Couldn't find it
Athlon II X3 435: Couldn't find it
Phenom II 945: 155€ (233,29320 dollars)
Phenom II 720: 120€ (180,61409 dollars)
Phenom II 955: 164,90€ (248,19387 dollars)
Phenom II 965: 177€ (266,40579 dollars)
The 965 in my opinion isn't worth it, mainly because there is only a difference in the multiplier, so you can easily convert a 955 into a 965
Hope that clears things out :)
