why X800 XT/FX-53 Poor oveclocking

[blackeye]

Why is the new hardware (X800 XT and FX-53) such poor performers when it comes to overclocking. The most i have seen the socket 939 fx53 get was 2.6 ghz with air cooling. And the x800 xt only 20-30 more mhz then its rated speed. Does this mean that both companies have to move to a new process from the 0.13 to 0.1 or whatever is next. Or does the poor performance have nothing to do with the mircron. When will some better OC parts come out?

 

[blahblahblah]

Where did you get this info from? I haven't heard anything about overclocking the FX-53, but I have read that the X800XT has some overclocking headroom in it.

Why would you even want to overclock them? They're at their peaks as it is. Christ some people are so ****ing performance hungry. OMG I CANT INSTALL WINDOWS XP IN 14 MINUTES IT TAKES 14 MINUTES AND 15 SECONDS WTFZORZ I HATE AMD AND ATI!

guinny i dont want to start a flame war cool down man.

That is a rather large OC for the Athlon64 actually.
Remember you cannot compare GHz with P4 and Athlon.
Each GHz on an Athlon is worth quite a bit more.

Think of what a 2.6GHz actually is.
3400+ is 2.2GHz
3600+ would be 2.4GHz
3800+ would be 2.6GHz
4000+ would be 2.8GHz
4200+ would be 3.0GHz
Of course that is using the Socket 754 single channel platform as an example.
Dual channel would be at least a full model above that.
2.6GHz would be a 4000+ for with dual channel but for both dual channel and 1MB L2 Cache then it would be better...which happens to be the FX55 when it is released.

I can't say about the X800XT...but if this helps, here is a review where they OCed the 6800 to 450MHz core speed and it doesn't really help a whole lot.

But yes, when both of them go to the 'next level', .09 micron, they will be allowed to clock higher.

We didn’t have high hopes about the overclockability of the new Socket 939 processors. As I mentioned above, they are all based on the same CG core revision as the Socket 940 Athlon 64 FX-53 we had tested earlier. Without extreme cooling methods, we had only reached a little over 2.6GHz clock rate for that processor. Considering also that the Athlon 64 3800+ is the last CPU model on the 130nm core, I may venture a supposition that Socket 939 Athlon 64 models should speed up to 2.5-2.6GHz and no more, without any special cooling.

That is an 8% overclock. It doesnt seem like to much when you look at how well some of the older athlons overclocked.

There ya go blahblahblah here is the XT information

x800 xt overclock

An increase of 17 and 24 mhz is not to great.

im not trying to start a flame war but jesus christ man your asking to take the two highest parts in those two fields and push them beyond what companies themselves arent doing. give it a rest man theyre at their peaks theres only so much cutting edge can do.

 

[blackeye]

I didnt say i was going to overclock it i just wanted to know why the increase is so minimul compared to the athlon xps

Over time they improve the cores and how well they can clock. At first you couldn't go much beyond 2.2GHz with the AXP's either. HP had a 2.3GHz AXP desktop part specially made by AMD and that was amazing at the time.

Also, they are using the AXP moble CPUs (Notebook binned CPUs) to OC that high. They havn't really got into the A64 moble CPUs just yet. They are just starting to look into it actually. The boards witht he PCI/AGP locks are just coming out as well. A few ppl have OCed the A64 3200+ DTR (DeskTop Replacement) Notebook CPUs to 2.5GHz.

 

[blackeye]

when will they change from 0.13 micron process though

A few ppl have OCed the A64 3200+ DTR (DeskTop Replacement) Notebook CPUs to 2.5GHz.

I have heard about that. Is it becuae they are able to run at higher temperatures more efficeintly or their wattage is lower?

 

[Asus]

They are going to .09 micron later this year.
Would you rather IM? lol

 

[blackeye]

Whats IM short for. Im confused :frown:

 

[ShinRa]

instant message

 

[blackeye]

lol. To many posts tonight lol

 

[SidewinderX]

well part of the reason is, like has been said, the basic technology hasn't advanced that much. You cna only clock things so high... these retial products are getting there, thus you cna't OC as much.

0.13 micron tech is already bieng pushed to the limits.
